(a) Timing of wage inclusion—(1) General timing rule for wages. Remuneration for employment that constitutes wages within the meaning of section 3121(a) generally is taken into account for purposes of the Federal Insurance Contributions Act (FICA) taxes imposed under sections 3101 and 3111 at the time the remuneration is actually or constructively paid. See §31.3121(a)-2(a).

(2) Special timing rule for an amount deferred under a nonqualified deferred compensation plan—(i) In general. To the extent that remuneration deferred under a nonqualified deferred compensation plan constitutes wages within the meaning of section 3121(a), the remuneration is subject to the special timing rule described in this paragraph (a)(2). Remuneration is considered deferred under a nonqualified deferred compensation plan within the meaning of section 3121(v)(2) and this section only if it is provided pursuant to a plan described in paragraph (b) of this section. The amount deferred under a nonqualified deferred compensation plan is determined under paragraph (c) of this section.

(ii) Special timing rule. Except as otherwise provided in this section, an amount deferred under a nonqualified deferred compensation plan is required to be taken into account as wages for FICA tax purposes as of the later of—

(A) The date on which the services creating the right to that amount are performed (within the meaning of paragraph (e)(2) of this section); or

(B) The date on which the right to that amount is no longer subject to a substantial risk of forfeiture (within the meaning of paragraph (e)(3) of this section).

(iii) Inclusion in wages only once (nonduplication rule). Once an amount deferred under a nonqualified deferred compensation plan is taken into account (within the meaning of paragraph (d)(1) of this section), then neither the amount taken into account nor the income attributable to the amount taken into account (within the meaning of paragraph (d)(2) of this section) is treated as wages for FICA tax purposes at any time thereafter.

(iv) Benefits that do not result from a deferral of compensation. If a nonqualified deferred compensation plan (within the meaning of paragraph (b)(1) of this section) provides both a benefit that results from the deferral of compensation (within the meaning of paragraph (b)(3) of this section) and a benefit that does not result from the deferral of compensation, the benefit that does not result from the deferral of compensation is not subject to the special timing rule described in this paragraph (a)(2). For example, if a nonqualified deferred compensation plan provides retirement benefits which result from the deferral of compensation and disability pay (within the meaning of paragraph (b)(4)(iv)(C) of this section) which does not result from the deferral of compensation, the retirement benefits provided under the plan are subject to the special timing rule in this paragraph (a)(2) and the disability pay is not.

(v) Remuneration that does not constitute wages. If remuneration under a nonqualified deferred compensation plan does not constitute wages within the meaning of section 3121(a), then that remuneration is not taken into account as wages for FICA tax purposes under either the general timing rule described in paragraph (a)(1) of this section or the special timing rule described in this paragraph (a)(2). For example, benefits under a death benefit plan described in section 3121(a)(13) do not constitute wages for FICA tax purposes. Therefore, these benefits are not included as wages under the general timing rule described in paragraph (a)(1) of this section or the special timing rule described in this paragraph (a)(2), even if the death benefit plan would otherwise be considered a nonqualified deferred compensation plan within the meaning of paragraph (b)(1) of this section.

(b) Nonqualified deferred compensation plan—(1) In general. For purposes of this section, the term nonqualified deferred compensation plan means any plan or other arrangement, other than a plan described in section 3121(a)(5), that is established (within the meaning of paragraph (b)(2) of this section) by an employer for one or more of its employees, and that provides for the deferral of compensation (within the meaning of paragraph (b)(3) of this section). A nonqualified deferred compensation plan may be adopted unilaterally by the employer or may be negotiated among or agreed to by the employer and one or more employees or employee representatives. A plan may constitute a nonqualified deferred compensation plan under this section without regard to whether the deferrals under the plan are made pursuant to an election by the employee or whether the amounts deferred are treated as deferred compensation for income tax purposes (e.g., whether the amounts are subject to the deduction rules of section 404). In addition, a plan may constitute a nonqualified deferred compensation plan under this section whether or not it is an employee benefit plan under section 3(3) of the Employee Retirement Income Security Act of 1974 (ERISA), as amended (29 U.S.C. 1002(3)). For purposes of this section, except where the context indicates otherwise, the term plan includes a plan or other arrangement.

(2) Plan establishment—(i) Date plan is established. For purposes of this section, a plan is established on the latest of the date on which it is adopted, the date on which it is effective, and the date on which the material terms of the plan are set forth in writing. For purposes of this section, a plan will be deemed to be set forth in writing if it is set forth in any other form that is approved by the Commissioner. The material terms of the plan include the amount (or the method or formula for determining the amount) of deferred compensation to be provided under the plan and the time when it may or will be provided.

(ii) Plan amendments. In the case of an amendment that increases the amount deferred under a nonqualified deferred compensation plan, the plan is not considered established with respect to the additional amount deferred until the plan, as amended, is established in accordance with paragraph (b)(2)(i) of this section.

(iii) Transition rule for written plan requirement. For purposes of this section, an unwritten plan that was adopted and effective before March 25, 1996, is treated as established under this section as of the later of the date on which it was adopted or became effective, provided that the material terms of the plan are set forth in writing before January 1, 2000.

(3) Plan must provide for the deferral of compensation—(i) Deferral of compensation defined. A plan provides for the deferral of compensation with respect to an employee only if, under the terms of the plan and the relevant facts and circumstances, the employee has a legally binding right during a calendar year to compensation that has not been actually or constructively received and that, pursuant to the terms of the plan, is payable to (or on behalf of) the employee in a later year. An employee does not have a legally binding right to compensation if that compensation may be unilaterally reduced or eliminated by the employer after the services creating the right to the compensation have been performed. For this purpose, compensation is not considered subject to unilateral reduction or elimination merely because it may be reduced or eliminated by operation of the objective terms of the plan, such as the application of an objective provision creating a substantial risk of forfeiture (within the meaning of section 83). Similarly, an employee does not fail to have a legally binding right to compensation merely because the amount of compensation is determined under a formula that provides for benefits to be offset by benefits provided under a plan that is qualified under section 401(a), or because benefits are reduced due to investment losses or, in a final average pay plan, subsequent decreases in compensation.

(ii) Compensation payable pursuant to the employer's customary payment timing arrangement. There is no deferral of compensation (within the meaning of this paragraph (b)(3)) merely because compensation is paid after the last day of a calendar year pursuant to the timing arrangement under which the employer ordinarily compensates employees for services performed during a payroll period described in section 3401(b).

(iii) Short-term deferrals. If, under a nonqualified deferred compensation plan, there is a deferral of compensation (within the meaning of this paragraph (b)(3)) that causes an amount to be deferred from a calendar year to a date that is not more than a brief period of time after the end of that calendar year, then, at the employer's option, that amount may be treated as if it were not subject to the special timing rule described in paragraph (a)(2) of this section. An employer may apply this option only if the employer does so for all employees covered by the plan and all substantially similar nonqualified deferred compensation plans. For purposes of this paragraph (b)(3)(iii), whether compensation is deferred to a date that is not more than a brief period of time after the end of a calendar year is determined in accordance with §1.404(b)-1T, Q&A-2, of this chapter.

(4) Plans, arrangements, and benefits that do not provide for the deferral of compensation—(i) In general. Notwithstanding paragraph (b)(3)(i) of this section, an amount or benefit described in any of paragraphs (b)(4)(ii) through (viii) of this section is not treated as resulting from the deferral of compensation for purposes of section 3121(v)(2) and this section and, thus, is not subject to the special timing rule of paragraph (a)(2) of this section.

(ii) Stock options, stock appreciation rights, and other stock value rights. The grant of a stock option, stock appreciation right, or other stock value right does not constitute the deferral of compensation for purposes of section 3121(v)(2). In addition, amounts received as a result of the exercise of a stock option, stock appreciation right, or other stock value right do not result from the deferral of compensation for purposes of section 3121(v)(2) if such amounts are actually or constructively received in the calendar year of the exercise. For purposes of this paragraph (b)(4)(ii), a stock value right is a right granted to an employee with respect to one or more shares of employer stock that, to the extent exercised, entitles the employee to a payment for each share of stock equal to the excess, or a percentage of the excess, of the value of a share of the employer's stock on the date of exercise over a specified price (greater than zero).

Thus, for example, the term stock value right does not include a phantom stock or other arrangement under which an employee is awarded the right to receive a fixed payment equal to the value of a specified number of shares of employer stock.

(iii) Restricted property. If an employee receives property from, or pursuant to, a plan maintained by an employer, there is no deferral of compensation (within the meaning of section 3121(v)(2)) merely because the value of the property is not includible in income (under section 83) in the year of receipt by reason of the property being nontransferable and subject to a substantial risk of forfeiture. However, a plan under which an employee obtains a legally binding right to receive property (whether or not the property is restricted property) in a future year may provide for the deferral of compensation within the meaning of paragraph (b)(3) of this section and, accordingly, may constitute a nonqualified deferred compensation plan, even though benefits under the plan are or may be paid in the form of property.

(iv) Certain welfare benefits—(A) In general. Vacation benefits, sick leave, compensatory time, disability pay, severance pay, and death benefits do not result from the deferral of compensation for purposes of section 3121(v)(2), even if those benefits constitute wages within the meaning of section 3121(a).

(B) Severance pay. Benefits that are provided under a severance pay arrangement (within the meaning of section 3(2)(B)(i) of ERISA) that satisfies the conditions in 29 CFR 2510.3-2(b)(1)(i) through (iii) are considered severance pay for purposes of this paragraph (b)(4)(iv). If benefits are provided under a severance pay arrangement (within the meaning of section 3(2)(B)(i) of ERISA), but do not satisfy one or more of the conditions in 29 CFR 2510.3-2(b)(1)(i) through (iii), then whether those benefits are severance pay within the meaning of this paragraph (b)(4)(iv) depends upon the relevant facts and circumstances. For this purpose, relevant facts and circumstances include whether the benefits are provided over a short period of time commencing immediately after (or shortly after) termination of employment or for a substantial period of time following termination of employment and whether the benefits are provided after any termination or only after retirement (or another specified type of termination). Benefits provided under a severance pay arrangement (within the meaning of section 3(2)(B)(i) of ERISA) are in all cases severance pay within the meaning of this paragraph (b)(4)(iv) if the benefits payable under the plan upon an employee's termination of employment are payable only if that termination is involuntary.

(C) Death benefits and disability pay—(1) General definition. Payments made under a nonqualified deferred compensation plan in the event of death are death benefits within the meaning of this paragraph (b)(4)(iv), but only to the extent the total benefits payable under the plan exceed the lifetime benefits payable under the plan. Similarly, payments made under a nonqualified deferred compensation plan in the event of disability are disability pay within the meaning of this paragraph (b)(4)(iv), but only to the extent the disability benefits payable under the plan exceed the lifetime benefits payable under the plan. Accordingly, any benefits that a nonqualified deferred compensation plan provides in the event of death or disability that are associated with an amount deferred under this section are disregarded in applying this section to the extent the benefits payable under the plan in the event of death or in the event of disability have a value in excess of the lifetime benefits payable under the plan.

(2) Total benefits payable defined. For purposes of paragraph (b)(4)(iv)(C)(1) of this section, the term total benefits payable under a plan means the present value of the total benefits payable to or on behalf of the employee (including benefits payable in the event of the employee's death) under the plan, disregarding any benefits that are payable only in the event of disability and determined separately with respect to each form of distribution or other election that may apply with respect to the employee.

(3) Disability benefits payable defined. For purposes of paragraph (b)(4)(iv)(C)(1) of this section, the term disability benefits payable under a plan means the present value of the benefits payable to or on behalf of the employee under the plan, including benefits payable in the event of the employee's disability but excluding death benefits within the meaning of this paragraph (b)(4)(iv).

(4) Lifetime benefits payable defined. For purposes of paragraph (b)(4)(iv)(C)(1) of this section, the term lifetime benefits payable under a plan means the present value of the benefits that could be payable to the employee under the plan during the employee's lifetime, determined under the plan's optional form of distribution or other election that is or was available to the employee at any time with respect to the amount deferred and that provides the largest present value to the employee during the employee's lifetime of any such form or election so available.

(5) Rules of application. For purposes of determining present value under this paragraph (b)(4)(iv)(C), present value is determined as of the time immediately preceding the time the amount deferred under a nonqualified deferred compensation plan is required to be taken into account under paragraph (e) of this section, using actuarial assumptions that are reasonable as of that date but taking into consideration only benefits that result from the deferral of compensation, as determined under this paragraph (b), and benefits payable in the event of death or disability. In addition, for purposes of paragraph (b)(4)(iv)(C)(4) of this section, present value must be determined without any discount for the probability that the employee may die before benefit payments commence and without regard to any benefits payable solely in the event of disability.

(v) Certain benefits provided in connection with impending termination—(A) In general. Benefits provided in connection with impending termination of employment under paragraph (b)(4)(v)(B) or (C) of this section do not result from the deferral of compensation within the meaning of section 3121(v)(2).

(B) Window benefits—(1) In general. For purposes of this paragraph (b)(4)(v), except as provided in paragraph (b)(4)(v)(B)(3) of this section, a window benefit is provided in connection with impending termination of employment. For this purpose, a window benefit is an early retirement benefit, retirement-type subsidy, social security supplement, or other form of benefit made available by an employer for a limited period of time (no greater than one year) to employees who terminate employment during that period or to employees who terminate employment during that period under specified circumstances.

(2) Special rule for recurring window benefits. A benefit will not be considered a window benefit if an employer establishes a pattern of repeatedly providing for similar benefits in similar situations for substantially consecutive, limited periods of time. Whether the recurrence of these benefits constitutes a pattern of amendments is determined based on the facts and circumstances. Although no one factor is determinative, relevant factors include whether the benefits are on account of a specific business event or condition, the degree to which the benefits relate to the event or condition, and whether the event or condition is temporary or discrete or is a permanent aspect of the employer's business.

(3) Transition rule for window benefits. In the case of a window benefit that is made available for a period of time that begins before January 1, 2000, an employer may choose to treat the window benefit as a benefit that results from the deferral of compensation if the sole reason the window benefit would otherwise fail to be provided pursuant to a nonqualified deferred compensation plan is the application of paragraph (b)(4)(v)(B)(1) of this section.

(C) Termination within 12 months of establishment of a benefit or plan. For purposes of this paragraph (b)(4)(v), a benefit is provided in connection with impending termination of employment, without regard to whether it constitutes a window benefit, if—

(1) An employee's termination of employment occurs within 12 months of the establishment of the plan (or amendment) providing the benefit; and

(2) The facts and circumstances indicate that the plan (or amendment) is established in contemplation of the employee's impending termination of employment.

(vi) Benefits established after termination. Benefits established with respect to an employee after the employee's termination of employment do not result from a deferral of compensation within the meaning of section 3121(v)(2). However, cost-of-living adjustments on benefit payments under a nonqualified deferred compensation plan (within the meaning of paragraph (b) of this section) shall not be considered benefits established after the employee's termination of employment for purposes of this paragraph (b)(4)(vi) merely because the employee does not obtain the right to the adjustment until after the employee's termination of employment. For purposes of the preceding sentence, cost-of-living adjustments are payments that satisfy conditions similar to those of 29 CFR 2510.3-2(g)(1)(ii) and (iii).

(vii) Excess parachute payments. An excess parachute payment (as defined in section 280G(b)) under an agreement entered into or renewed after June 14, 1984, in taxable years ending after such date, does not result from the deferral of compensation within the meaning of section 3121(v)(2). For this purpose, any contract entered into before June 15, 1984, that is amended after June 14, 1984, in any relevant significant aspect, is treated as a contract entered into after June 14, 1984.

(viii) Compensation for current services. A plan does not provide for the deferral of compensation within the meaning of section 3121(v)(2) if, based on the relevant facts and circumstances, the compensation is paid for current services.

(5) Examples. This paragraph (b) is illustrated by the following examples:

(c) Determination of the amount deferred—(1) Account balance plans—(i) General rule. For purposes of this section, if benefits for an employee are provided under a nonqualified deferred compensation plan that is an account balance plan, the amount deferred for a period equals the principal amount credited to the employee's account for the period, increased or decreased by any income attributable to the principal amount through the date the principal amount is required to be taken into account as wages under paragraph (e) of this section.

(ii) Definitions—(A) Account balance plan. For purposes of this section, an account balance plan is a nonqualified deferred compensation plan under the terms of which a principal amount (or amounts) is credited to an individual account for an employee, the income attributable to each principal amount is credited (or debited) to the individual account, and the benefits payable to the employee are based solely on the balance credited to the individual account.

(B) Income. For purposes of this section, income means any increase or decrease in the amount credited to an employee's account that is attributable to amounts previously credited to the employee's account, regardless of whether the plan denominates that increase or decrease as income.

(iii) Additional rules—(A) Commingled accounts. A plan does not fail to be an account balance plan merely because, under the terms of the plan, benefits payable to an employee are based solely on a specified percentage of an account maintained for all (or a portion of) plan participants under which principal amounts and income are credited (or debited) to such account.

(B) Bifurcation permitted. An employer may treat a portion of a nonqualified deferred compensation plan as a separate account balance plan if that portion satisfies the requirements of this paragraph (c)(1) and the amount payable to employees under that portion is determined independently of the amount payable under the other portion of the plan.

(C) Actuarial equivalents. A plan does not fail to be an account balance plan merely because the plan permits employees to elect to receive their benefits under the plan in a form of benefit other than payment of the account balance, provided the amount of benefit payable in that other form is actuarially equivalent to payment of the account balance using actuarial assumptions that are reasonable. Conversely, a plan is not an account balance plan if it provides an optional form of benefit that is not actuarially equivalent to the account balance using actuarial assumptions that are reasonable. For this purpose, the determination of whether forms are actuarially equivalent using actuarial assumptions that are reasonable is determined under the rules applicable to nonaccount balance plans under paragraph (c)(2)(iii) of this section.

(2) Nonaccount balance plans—(i) General rule. For purposes of this section, if benefits for an employee are provided under a nonqualified deferred compensation plan that is not an account balance plan (a nonaccount balance plan), the amount deferred for a period equals the present value of the additional future payment or payments to which the employee has obtained a legally binding right (as described in paragraph (b)(3)(i) of this section) under the plan during that period.

(ii) Present value defined. For purposes of this section, present value means the value as of a specified date of an amount or series of amounts due thereafter, where each amount is multiplied by the probability that the condition or conditions on which payment of the amount is contingent will be satisfied, and is discounted according to an assumed rate of interest to reflect the time value of money. For purposes of this section, the present value must be determined as of the date the amount deferred is required to be taken into account as wages under paragraph (e) of this section using actuarial assumptions and methods that are reasonable as of that date. For this purpose, a discount for the probability that an employee will die before commencement of benefit payments is permitted, but only to the extent that benefits will be forfeited upon death. In addition, the present value cannot be discounted for the probability that payments will not be made (or will be reduced) because of the unfunded status of the plan, the risk associated with any deemed or actual investment of amounts deferred under the plan, the risk that the employer, the trustee, or another party will be unwilling or unable to pay, the possibility of future plan amendments, the possibility of a future change in the law, or similar risks or contingencies. Nor is the present value affected by the possibility that some of the payments due under the plan will be eligible for one of the exclusions from wages in section 3121(a).

(iii) Treatment of actuarially equivalent benefits—(A) In general. In the case of a nonaccount balance plan that permits employees to receive their benefits in more than one form or commencing at more than one date, the amount deferred is determined by assuming that payments are made in the normal form of benefit commencing at normal commencement date if the requirements of paragraph (c)(2)(iii)(B) of this section are satisfied. Accordingly, in the case of a nonaccount balance plan that permits employees to receive their benefits in more than one form or commencing at more than one date, unless the requirements of paragraph (c)(2)(iii)(B) of this section are satisfied, the amount deferred is treated as not reasonably ascertainable under the rules of paragraph (e)(4)(i)(B) of this section until a form of benefit and a time of commencement are selected.

(B) Use of normal form commencing at normal commencement date. The requirements of this paragraph (c)(2)(iii)(B) are satisfied by a nonaccount balance plan if the plan has a single normal form of benefit commencing at normal commencement date for the amount deferred and each other optional form is actuarially equivalent to the normal form of benefit commencing at normal commencement date using actuarial assumptions that are reasonable. For this purpose, each form of benefit for payment of the amount deferred commencing at a date is a separate optional form. For purposes of this paragraph (c)(2)(iii)(B), each optional form is actuarially equivalent to the normal form of benefit commencing at normal commencement date only if the terms of the plan in effect when the amount is deferred provide for every optional form to be actuarially equivalent and further provide for actuarial assumptions to determine actuarial equivalency that will be reasonable at the time the optional form is selected, without regard to whether market interest rates are higher or lower at the time the optional form is selected than at the time the amount is deferred. Thus, a plan that provides for every optional form to be actuarially equivalent satisfies this paragraph (c)(2)(iii)(B) if it provides for actuarial equivalence to be determined—

(1) When an optional form is selected or when benefit payments under the optional form commence, based on assumptions that are reasonable then;

(2) Based on an index that reflects market rates of interest from time to time (for example, the plan specifies that all benefits will be actuarially equivalent using the applicable interest rate and applicable mortality table specified in section 417(e)); or

(3) Based on actuarial assumptions specified in the plan and provides for those assumptions to be revised to be reasonable assumptions if they cease to be reasonable assumptions.

(C) Fixed mortality assumptions permitted. A plan does not fail to satisfy paragraph (c)(2)(iii)(B) of this section merely because the plan specifies a fixed mortality assumption that is reasonable at the time the amount is deferred, even if that assumption is not reasonable at the time the optional form is selected. (But see paragraph (c)(2)(iii)(E) of this section for additional rules that apply if the mortality assumption is not reasonable at the time the optional form is selected.)

(D) Normal form of benefit commencing at normal commencement date defined. For purposes of this paragraph (c)(2)(iii), the normal form of benefit commencing at normal commencement date under the plan is the form, and date of commencement, under which the payments due to the employee under the plan are expressed, prior to adjustments for form or timing of commencement of payments.

(E) Rule applicable if actuarial assumptions cease to be reasonable. If the terms of the plan in effect when an amount is deferred provide for actuarial assumptions to determine actuarial equivalency that will be reasonable at the time the optional form is selected or payments commence as provided in paragraph (c)(2)(iii)(B) of this section, but, at that time, the actuarial assumptions used under the plan are not reasonable, the employee will be treated as obtaining a legally binding right at that time (or, if earlier, at the date on which the plan is amended to provide actuarial assumptions that are not reasonable) to any additional benefits that result from the use of an unreasonable actuarial assumption. This might occur, for example, if the plan specifies that the actuarial assumptions will be reasonable assumptions to be set at the time the optional form is selected and the assumptions used are in fact not reasonable at that time.

(3) Separate determination for each period. The amount deferred under this paragraph (c) is determined separately for each period for which there is an amount deferred under the plan. In addition, paragraphs (d) and (e) of this section are applied separately with respect to the amount deferred for each such period. Thus, for example, the fraction described in paragraph (d)(1)(ii)(B) of this section and the amount of the true-up at the resolution date described in paragraph (e)(4)(ii)(B) of this section are determined separately with respect to each amount deferred. See paragraph (e)(4)(ii)(D) of this section for special rules for allocating amounts deferred over more than one year.

(4) Examples. This paragraph (c) is illustrated by the following examples. (The examples illustrate the rules in this paragraph (c) and include various interest rate and mortality table assumptions, including the applicable section 417(e) mortality table, the GAM 83 (male) mortality table, and UP-84 mortality table. These tables can be obtained from the Society of Actuaries at its internet site at http://www.soa.org.) The examples are as follows:

(d) Amounts taken into account and income attributable thereto—(1) Amounts taken into account—(i) In general. For purposes of this section, an amount deferred under a nonqualified deferred compensation plan is taken into account as of the date it is included in computing the amount of wages as defined in section 3121(a), but only to the extent that any additional FICA tax that results from such inclusion (including any interest and penalties for late payment) is actually paid before the expiration of the applicable period of limitations for the period in which the amount deferred was required to be taken into account under paragraph (e) of this section. Because an amount deferred for a calendar year is combined with the employee's other wages for the year for purposes of computing FICA taxes with respect to the employee for the year, if the employee has other wages that equal or exceed the wage base limitations for the Old-Age, Survivors, and Disability Insurance (OASDI) portion (or, in the case of years before 1994, the Hospital Insurance (HI) portion) of FICA for the year, no portion of the amount deferred will actually result in additional OASDI (or HI) tax. However, because there is no wage base limitation for the HI portion of FICA for years after 1993, the entire amount deferred (in addition to all other wages) is subject to the HI tax for the year and, thus, will not be considered taken into account for purposes of this section unless the HI tax relating to the amount deferred is actually paid. In determining whether any additional FICA tax relating to the amount deferred is actually paid, any FICA tax paid in a year is treated as paid with respect to an amount deferred only after FICA tax is paid on all other wages for the year.

(ii) Amounts not taken into account—(A) Failure to take an amount deferred into account under the special timing rule. If an amount deferred for a period (as determined under paragraph (c) of this section) is not taken into account, then the nonduplication rule of paragraph (a)(2)(iii) of this section does not apply, and benefit payments attributable to that amount deferred are included as wages in accordance with the general timing rule of paragraph (a)(1) of this section. For example, if an amount deferred is required to be taken into account in a particular year under paragraph (e) of this section, but the employer fails to pay the additional FICA tax resulting from that amount, then the amount deferred and the income attributable to that amount must be included as wages when actually or constructively paid.

(B) Failure to take a portion of an amount deferred into account under the special timing rule. If, as of the date an amount deferred is required to be taken into account, only a portion of the amount deferred (as determined under paragraph (c) of this section) has been taken into account, then a portion of each subsequent benefit payment that is attributable to that amount is excluded from wages pursuant to the nonduplication rule of paragraph (a)(2)(iii) of this section and the balance is subject to the general timing rule of paragraph (a)(1) of this section. The portion that is excluded from wages is fixed immediately before the attributable benefit payments commence (or, if later, the date the amount deferred is required to be taken into account) and is determined by multiplying each such payment by a fraction, the numerator of which is the amount that was taken into account (plus income attributable to that amount determined under paragraph (d)(2) of this section through the date the portion is fixed) and the denominator of which is the present value of the future benefit payments attributable to the amount deferred, determined as of the date the portion is fixed. For this purpose, if the requirements of paragraph (c)(2)(iii)(B) of this section are satisfied, the present value is determined by assuming that payments are made in the normal form of benefit commencing at normal commencement date. In addition, if the employer demonstrates that the amount deferred was determined using reasonable actuarial assumptions as determined by the Commissioner, the present value of the future benefit payments attributable to the amount deferred is determined using those assumptions. In any other case, see paragraph (d)(2)(iii) of this section.

(2) Income attributable to the amount taken into account—(i) Account balance plans—(A) In general. For purposes of the nonduplication rule of paragraph (a)(2)(iii) of this section, in the case of an account balance plan, the income attributable to the amount taken into account means any amount credited on behalf of an employee under the terms of the plan that is income (within the meaning of paragraph (c)(1)(ii)(B) of this section) attributable to an amount previously taken into account (within the meaning of paragraph (d)(1) of this section), but only if the income reflects a rate of return that does not exceed either the rate of return on a predetermined actual investment (as determined in accordance with paragraph (d)(2)(i)(B) of this section) or, if the income does not reflect the rate of return on a predetermined actual investment (as so determined), a reasonable rate of interest (as determined in accordance with paragraph (d)(2)(i)(C) of this section).

(B) Rules relating to actual investment—(1) In general. For purposes of this paragraph (d)(2)(i), the rate of return on a predetermined actual investment for any period means the rate of total return (including increases or decreases in fair market value) that would apply if the account balance were, during the applicable period, actually invested in one or more investments that are identified in accordance with the plan before the beginning of the period. For this purpose, an account balance plan can determine income based on the rate of return of a predetermined actual investment regardless of whether assets associated with the plan or the employer are actually invested therein and regardless of whether that investment is generally available to the public. For example, an account balance plan could provide that income on the account balance is determined based on an employee's prospective election among various investment alternatives that are available under the employer's section 401(k) plan, even if one of those investment alternatives is not generally available to the public. In addition, an actual investment includes an investment identified by reference to any stock index with respect to which there are positions traded on a national securities exchange described in section 1256(g)(7)(A).

(2) Certain rates of return not based on predetermined actual investment. A rate of return will not be treated as the rate of return on a predetermined actual investment within the meaning of this paragraph (d)(2)(i)(B) if the rate of return (to any extent or under any conditions) is based on the greater of the rate of return of two or more actual investments, is based on the greater of the rate of return on an actual investment and a rate of interest (whether or not the rate of interest would otherwise be reasonable under paragraph (d)(2)(i)(C) of this section), or is based on the rate of return on an actual investment that is not predetermined. For example, if a plan bases the rate of return on the greater of the rate of return on a predetermined actual investment (such as the value of the employer's stock), and a 0 percent interest rate (i.e., without regard to decreases in the value of that investment), the plan is using a rate of return that is not a rate of return on a predetermined actual investment within the meaning of this paragraph (d)(2)(i)(B).

(C) Rules relating to reasonable interest rates—(1) In general. If income for a period is credited to an account balance plan on a basis other than the rate of return on a predetermined actual investment (as determined in accordance with paragraph (d)(2)(i)(B) of this section), then, except as otherwise provided in this paragraph (d)(2)(i)(C), the determination of whether the income for the period is based on a reasonable rate of interest will be made at the time the amount deferred is required to be taken into account and annually thereafter.

(2) Fixed rates permitted. If, with respect to an amount deferred for a period, an account balance plan provides for a fixed rate of interest to be credited, and the rate is to be reset under the plan at a specified future date that is not later than the end of the fifth calendar year that begins after the beginning of the period, the rate is reasonable at the beginning of the period, and the rate is not changed before the reset date, then the rate will be treated as reasonable in all future periods before the reset date.

(ii) Nonaccount balance plans. For purposes of the nonduplication rule of paragraph (a)(2)(iii) of this section, in the case of a nonaccount balance plan, the income attributable to the amount taken into account means the increase, due solely to the passage of time, in the present value of the future payments to which the employee has obtained a legally binding right, the present value of which constituted the amount taken into account (determined as of the date such amount was taken into account), but only if the amount taken into account was determined using reasonable actuarial assumptions and methods. Thus, for each year, there will be an increase (determined using the same interest rate used to determine the amount taken into account) resulting from the shortening of the discount period before the future payments are made, plus, if applicable, an increase in the present value resulting from the employee's survivorship during the year. As a result, if the amount deferred for a period is determined using a reasonable interest rate and other reasonable actuarial assumptions and methods, and the amount is taken into account when required under paragraph (e) of this section, then, under the nonduplication rule of paragraph (a)(2)(iii) of this section, none of the future payments attributable to that amount will be subject to FICA tax when paid.

(iii) Unreasonable rates of return—(A) Account balance plans. This paragraph (d)(2)(iii)(A) applies to an account balance plan under which the income credited is based on neither a predetermined actual investment, within the meaning of paragraph (d)(2)(i)(B) of this section, nor a rate of interest that is reasonable, within the meaning of paragraph (d)(2)(i)(C) of this section, as determined by the Commissioner. In that event, the employer must calculate the amount that would be credited as income under a reasonable rate of interest, determine the excess (if any) of the amount credited under the plan over the income that would be credited using the reasonable rate of interest, and take that excess into account as an additional amount deferred in the year the income is credited. If the employer fails to calculate the amount that would be credited as income under a reasonable rate of interest and to take the excess into account as an additional amount deferred in the year the income is credited, or the employer otherwise fails to take the full amount deferred into account, then the excess of the income credited under the plan over the income that would be credited using AFR will be treated as an amount deferred in the year the income is credited. For purposes of this section, AFR means the mid-term applicable federal rate (as defined pursuant to section 1274(d)) for January 1 of the calendar year, compounded annually. In addition, pursuant to paragraph (d)(1)(ii) of this section, the excess over the income that would result from the application of AFR and any income attributable to that excess are subject to the general timing rule of paragraph (a)(1) of this section.

(B) Nonaccount balance plans. If any actuarial assumption or method used to determine the amount taken into account under a nonaccount balance plan is not reasonable, as determined by the Commissioner, then the income attributable to the amount taken into account is limited to the income that would result from the application of the AFR and, if applicable, the applicable mortality table under section 417(e)(3)(A)(ii)(I) (the 417(e) mortality table), both determined as of the January 1 of the calendar year in which the amount was taken into account. In addition, paragraph (d)(1)(ii)(B) of this section applies and, in calculating the fraction described in paragraph (d)(1)(ii)(B) of this section (at the date specified in paragraph (d)(1)(ii)(B) of this section), the numerator is the amount taken into account plus income (as limited under this paragraph (d)(2)(iii)(B)), and the present value in the denominator is determined using the AFR, the 417(e) mortality table, and reasonable assumptions as to cost of living, each determined as of the time the amount deferred was required to be taken into account.

(3) Examples. This paragraph (d) is illustrated by the following examples:

(e) Time amounts deferred are required to be taken into account—(1) In general. Except as otherwise provided in this paragraph (e), an amount deferred under a nonqualified deferred compensation plan must be taken into account as wages for FICA tax purposes as of the later of the date on which services creating the right to the amount deferred are performed (within the meaning of paragraph (e)(2) of this section) or the date on which the right to the amount deferred is no longer subject to a substantial risk of forfeiture (within the meaning of paragraph (e)(3) of this section). However, in no event may any amount deferred under a nonqualified deferred compensation plan be taken into account as wages for FICA tax purposes prior to the establishment of the plan providing for the amount deferred (or, if later, the plan amendment providing for the amount deferred). Therefore, if an amount is deferred pursuant to the terms of a legally binding agreement that is not put in writing until after the amount would otherwise be taken into account under this paragraph (e)(1), the amount deferred (including any attributable income) must be taken into account as wages for FICA tax purposes as of the date the material terms of the plan are put in writing.

(2) Services creating the right to an amount deferred. For purposes of this section, services creating the right to an amount deferred under a nonqualified deferred compensation plan are considered to be performed as of the date on which, under the terms of the plan and all the facts and circumstances, the employee has performed all of the services necessary to obtain a legally binding right (as described in paragraph (b)(3)(i) of this section) to the amount deferred.

(3) Substantial risk of forfeiture. For purposes of this section, the determination of whether a substantial risk of forfeiture exists must be made in accordance with the principles of section 83 and the regulations thereunder.

(4) Amount deferred that is not reasonably ascertainable under a nonaccount balance plan—(i) In general—(A) Date required to be taken into account. Notwithstanding any other provision of this paragraph (e), an amount deferred under a nonaccount balance plan is not required to be taken into account as wages under the special timing rule of paragraph (a)(2) of this section until the first date on which all of the amount deferred is reasonably ascertainable (the resolution date). In this case, the amount required to be taken into account as of the resolution date is determined in accordance with paragraph (c)(2) of this section.

(B) Definition of reasonably ascertainable. For purposes of this paragraph (e)(4), an amount deferred is considered reasonably ascertainable on the first date on which the amount, form, and commencement date of the benefit payments attributable to the amount deferred are known, and the only actuarial or other assumptions regarding future events or circumstances needed to determine the amount deferred are interest and mortality. For this purpose, the form and commencement date of the benefit payments attributable to the amount deferred are treated as known if the requirements of paragraph (c)(2)(iii)(B) of this section (under which payments are treated as being made in the normal form of benefit commencing at normal commencement date) are satisfied. In addition, an amount deferred does not fail to be reasonably ascertainable on a date merely because the exact amount of the benefit payable cannot readily be calculated on that date or merely because the exact amount of the benefit payable depends on future changes in the cost of living. If the exact amount of the benefit payable depends on future changes in the cost of living, the amount deferred must be determined using a reasonable assumption as to the future changes in the cost of living. For example, the amount of a benefit is treated as known even if the exact amount of the benefit payable cannot be determined until future changes in the cost of living are reflected in the section 415 limitation on benefits payable under a qualified retirement plan.

(ii) Earlier inclusion permitted—(A) In general. With respect to an amount deferred that is not reasonably ascertainable, an employer may choose to take an amount into account at any date or dates (an early inclusion date or dates) before the resolution date (but not before the date described in paragraph (e)(1) of this section with respect to the amount deferred). Thus, for example, with respect to an amount deferred under a nonaccount balance plan that is not reasonably ascertainable because the plan permits employees to receive their benefits in more than one form or commencing at more than one date (and the requirements of paragraph (c)(2)(iii) of this section are not satisfied), an employer may choose to take an amount into account on the date otherwise described in paragraph (e)(1) of this section before the form and commencement date are selected (based on assumptions as to the form and commencement date for the benefit payments) or may choose to wait until the form and commencement date of the benefit payments are selected. An employer that chooses to take an amount into account at an early inclusion date under this paragraph (e)(4)(ii) for an employee under a plan is not required until the resolution date to identify the period to which the amount taken into account relates.

(B) True-up at resolution date. If, with respect to an amount deferred for a period, an employer chooses to take an amount into account as of an early inclusion date in accordance with this paragraph (e)(4)(ii) and the benefit payments attributable to the amount deferred exceed the benefit payments that are actuarially equivalent to the amount taken into account at the early inclusion date (payable in the same form and using the same commencement date as the benefit payments attributable to the amount deferred), then the present value of the difference in the benefits, determined in accordance with paragraph (c)(2) of this section, must be taken into account as of the resolution date.

(C) Actuarial assumptions. For purposes of determining the benefits that are actuarially equivalent to the amount taken into account as of an early inclusion date, the amount taken into account is converted to an actuarially equivalent benefit payable in the same form and commencing on the same date as the actual benefit payments attributable to the amount deferred using an interest rate, and, if applicable, mortality and cost-of-living assumptions, that were reasonable as of the early inclusion date. Thus, with respect to an amount deferred for a period, the amount required to be taken into account as of the resolution date is the present value (determined using an interest rate, and, if applicable, mortality and cost-of-living assumptions, that are reasonable as of the resolution date) of the excess, if any, of the future benefit payments attributable to the amount deferred over the future benefits payable in the same form and commencing on the same date that are actuarially equivalent to the portion of the amount deferred that was taken into account as of the early inclusion date (where actuarial equivalence is determined using an interest rate, and, if applicable, mortality and cost-of-living assumptions, that were reasonable as of the early inclusion date).

(D) Allocation rules for amounts deferred over more than one period—(1) General rule. The rules of this paragraph (e)(4)(ii)(D) apply for purposes of determining whether an amount has been included under this paragraph (e)(4) before the earliest date permitted under paragraph (e)(1) of this section.

(2) Future compensation increases. Increases in an employee's compensation after the early inclusion date must be disregarded.

(3) Early retirement subsidies. An early retirement subsidy that the employee ultimately receives may be taken into account at an early inclusion date if the employee would have a legally binding right to the subsidy at the early inclusion date but for any condition that the employee continue to render services. Accordingly, an employer may take into account at an early inclusion date any early retirement subsidy that the employee ultimately receives to the extent that elimination or reduction of that subsidy would violate section 411(d)(6)(B)(i) if that section applied to the plan.

(4) Allocation with respect to offsets. In any case in which a series of amounts are deferred over more than one period, the amounts deferred are not reasonably ascertainable until a single resolution date and the benefit payments attributable to the entire series are determined under a formula that provides a gross benefit that in the aggregate is subject to an objective reduction for future events under the terms of the plan, such as an offset for the aggregate benefits payable under a plan qualified under section 401(a), the attribution of benefit payments to the amount deferred in each period is determined under the rules of this paragraph (e)(4)(ii)(D)(4). In a case described in the preceding sentence, the benefit payments made as a result of the series of amounts deferred may be treated as attributable to the amount deferred as of the earliest period in which the employee obtained a legally binding right to a benefit under the plan equal to the excess, if any, of the amount of the gross benefit attributable to that period (determined at the resolution date), over the amount of the reduction determined as of the end of that period. Thus, for example, if an employee obtains a legally binding right in each of several years to benefit payments from a nonqualified deferred compensation plan that provides for a specified gross benefit for the years to be offset by the benefits payable under a qualified plan, the amount deferred in the first year may be treated as equal to the gross benefit for the year, reduced by the offset applicable at the end of the year (even if the offset increases after the end of the year).

(E) Treatment of benefits paid before the resolution date. If a benefit payment is attributable to an amount deferred that is not reasonably ascertainable at the time of payment (or is paid before the date selected under paragraph (e)(5) of this section), and the employer has previously taken an amount into account with respect to the amount deferred under the early inclusion rule of this paragraph (e)(4), then, in lieu of the pro rata rule provided in paragraph (d)(1)(ii)(B) of this section, a first-in-first-out rule applies in determining the portion of the benefit payment attributable to the amount taken into account. Under this first-in-first-out rule, the benefit payment is compared to the sum of the amount taken into account at the early inclusion date and the income attributable to that amount. If the benefit payment equals or exceeds the amount taken into account at the early inclusion date and the income attributable to that amount as of the date of the benefit payment, the benefit payment is included as wages under the general timing rule of paragraph (a)(1) of this section to the extent of any excess, and the amount taken into account at the early inclusion date (and income attributable to that amount) is disregarded thereafter with respect to the amount deferred. If the amount taken into account at the early inclusion date and the income attributable to that amount as of the date of the benefit payment exceeds the benefit payment, the benefit payment is not included as wages under the general timing rule of paragraph (a)(1) of this section and, in determining the amount that must be taken into account thereafter with respect to the amount deferred, the amount taken into account at the early inclusion date, plus attributable income as of the date of the benefit payment, is reduced by the amount of the benefit payment, and only the excess plus future income attributable to the excess (credited using assumptions that were reasonable on the early inclusion date) is taken into consideration. If amounts have been taken into account at more than one early inclusion date, this paragraph (e)(4)(ii)(E) applies on a first-in-first-out basis, beginning with the amount taken into account at the earliest early inclusion date (including income attributable thereto).

(5) Rule of administrative convenience. For purposes of this section, an employer may treat an amount deferred as required to be taken into account under this paragraph (e) on any date that is later than, but within the same calendar year as, the actual date on which the amount deferred is otherwise required to be taken into account under this paragraph (e). For example, if services creating the right to an amount deferred are considered performed under paragraph (e)(2) of this section periodically throughout a year, the employer may nevertheless treat the services creating the right to that amount deferred as performed on December 31 of that year. If an employer uses the rule of administrative convenience described in this paragraph (e)(5), any determination of whether the income attributable to an amount deferred under an account balance plan is based on a reasonable rate of interest or whether the actuarial assumptions used to determine the present value of an amount deferred in a nonaccount balance plan are reasonable will be made as of the date the employer selects to take the amount into account.

(6) Portions of an amount deferred required to be taken into account on more than one date. If different portions of an amount deferred are required to be taken into account under paragraph (e)(1) of this section on more than one date (e.g., on account of a graded vesting schedule), then each such portion is considered a separate amount deferred for purposes of this section.

(7) Examples. This paragraph (e) is illustrated by the following examples:

(f) Withholding—(1) In general. Unless an employer applies an alternative method described in paragraph (f)(2) or (3) of this section, an amount deferred under a nonqualified deferred compensation plan for any employee is treated, for purposes of withholding and depositing FICA tax, as wages paid by the employer and received by the employee at the time it is taken into account in accordance with paragraph (e) of this section. However, paragraphs (f)(2) and (3) of this section provide alternative methods which may be used with respect to an amount deferred for an employee. An employer is not required to be consistent in applying the alternatives described in this paragraph (f) with respect to different employees or amounts deferred.

(2) Estimated method—(i) In general. Under the alternative method provided in this paragraph (f)(2), the employer may make a reasonable estimate of the amount deferred on the date on which the amount is taken into account in accordance with paragraph (e) of this section and take that estimated amount into account as wages paid by the employer and received by the employee on that date (the estimate date), for purposes of withholding and depositing FICA tax.

(ii) Underestimate of the amount deferred—(A) General rule. If the employer underestimates the amount deferred (as determined after calculating the actual amount deferred that should have been taken into account as of the date on which the amount was taken into account in accordance with paragraph (e) of this section, using an interest rate and other actuarial assumptions that are reasonable as of that date), the employer may treat the shortfall as wages paid as of the estimate date or as of any date that is no later than three months after the estimate date. In either case, the shortfall does not include the income credited to the amount deferred after the amount is taken into account in accordance with paragraph (e) of this section.

(B) Shortfall is treated as wages paid on a date after the estimate date. If the employer chooses to treat the shortfall as wages paid on a date that is no later than three months after the estimate date, the employer must take that shortfall into account as wages paid by the employer and received by the employee on that date, for purposes of withholding and depositing FICA tax.

(C) Shortfall is treated as wages paid on the estimate date. If the employer chooses to treat the shortfall as wages paid as of the estimate date, the shortfall is treated as an error for purposes of withholding and depositing FICA tax. Appropriate adjustments may be made in accordance with section 6205(a) and the regulations thereunder; however, for purposes of §31.6205-1(b), the error need not be treated as ascertained before the date that is three months after the estimate date.

(D) Reporting. The employer must report the shortfall as wages on Form 941, Employer's Quarterly Federal Tax Return (and, if applicable, Form 941c, Supporting Statement to Correct Information) and Form W-2, Wage and Tax Statement (or, if applicable, Form W-2c, Corrected Wage and Tax Statement) in accordance with its treatment of the shortfall under paragraph (f)(2)(ii) (B) or (C) of this section.

(iii) Overestimate of the amount deferred. If the employer overestimates the amount deferred (as determined after calculating the actual amount deferred that should have been taken into account as of the date on which the amount was taken into account in accordance with paragraph (e) of this section, using an interest rate and actuarial assumptions that are reasonable as of that date) and deposits more than the amount required, the employer may claim a refund or credit in accordance with sections 6402, 6413, and 6511. A Form 941c, or an equivalent statement, must accompany each claim for refund. In addition, Form W-2 or, if applicable, Form W-2c must also reflect the actual amount deferred that should have been taken into account.

(3) Lag method. Under the alternative method provided in this paragraph (f)(3), an amount deferred, plus interest, may be treated as wages paid by the employer and received by the employee, for purposes of withholding and depositing FICA tax, on any date that is no later than three months after the date the amount is required to be taken into account in accordance with paragraph (e) of this section. For purposes of this paragraph (f)(3), the amount deferred must be increased by interest through the date on which the wages are treated as paid, at a rate that is not less than AFR. If the employer withholds and deposits FICA tax in accordance with this paragraph (f)(3), the employer will be treated as having taken into account the amount deferred plus income to the date on which the wages are treated as paid.

(4) Examples. This paragraph (f) is illustrated by the following examples:

(g) Effective date and transition rules—(1) General effective date. Except for paragraphs (g)(2) through (4) of this section, this section is applicable on and after January 1, 2000. Thus, paragraphs (a) through (f) of this section apply to amounts deferred on or after January 1, 2000; to amounts deferred before January 1, 2000, which cease to be subject to a substantial risk of forfeiture on or after January 1, 2000, or for which a resolution date occurs on or after January 1, 2000; and to benefits actually or constructively paid on or after January 1, 2000.

(2) Reasonable, good faith interpretation for amounts deferred and benefits paid before January 1, 2000—(i) In general. For periods before January 1, 2000 (including amounts deferred before January 1, 2000, and any benefits actually or constructively paid before January 1, 2000, that are attributable to those amounts deferred), an employer may rely on a reasonable, good faith interpretation of section 3121(v)(2), taking into account pre-existing guidance. An employer will be deemed to have determined FICA tax liability and satisfied FICA withholding requirements in accordance with a reasonable, good faith interpretation of section 3121(v)(2) if the employer has complied with paragraphs (a) through (f) of this section. For purposes of paragraphs (g)(2) through (4) of this section, and subject to paragraphs (g)(2)(ii) and (iii) of this section, whether an employer that has not complied with paragraphs (a) through (f) of this section has determined FICA tax liability and satisfied FICA withholding requirements in accordance with a reasonable, good faith interpretation of section 3121(v)(2) will be determined based on the relevant facts and circumstances, including consistency of treatment by the employer and the extent to which the employer has resolved unclear issues in its favor.

(ii) Plan must be established or adopted. If an amount is deferred under a plan before January 1, 2000, and benefit payments attributable to that amount are actually or constructively paid on or after January 1, 2000, then in no event will an employer's treatment of the amount deferred be considered to be in accordance with a reasonable, good faith interpretation of section 3121(v)(2) if the employer treats that amount as taken into account as wages for FICA tax purposes prior to the establishment of the plan (within the meaning of paragraph (b)(2) of this section) providing for the deferred compensation (or, if later, the establishment of the plan as amended to provide for the deferred compensation, as provided in paragraph (b)(2)(ii) of this section). If an amount is deferred under a plan before January 1, 2000, and benefit payments attributable to that amount are actually or constructively paid before January 1, 2000, then in no event will the employer's treatment of that amount deferred be considered to be in accordance with a reasonable, good faith interpretation of section 3121(v)(2) if the employer treats that amount as taken into account as wages for FICA tax purposes prior to the adoption of the plan providing for the deferred compensation (or, if later, the adoption of the plan amendment providing the deferred compensation). For example, awards, bonuses, raises, incentive payments, and other similar amounts granted under a plan as compensation for past services may not be taken into account under section 3121(v)(2) prior to the establishment (or, if applicable, the adoption) of the plan.

(iii) Certain changes in position for stock options, stock appreciation rights, and other stock value rights not reasonable, good faith interpretation. In the case of a stock option, stock appreciation right, or other stock value right (as defined in paragraph (b)(4)(ii) of this section) that is exercised before January 1, 2000, an employer that treats the exercise as not subject to FICA tax as a result of the nonduplication rule of section 3121(v)(2)(B) is not acting in accordance with a reasonable, good faith interpretation of section 3121(v)(2) if the employer has not treated that grant and all earlier grants as subject to section 3121(v)(2) by reporting the current value of such options and rights as FICA wages on Form 941 filed for the quarter during which each grant was made (or, if later, for the quarter during which each grant ceased to be subject to a substantial risk of forfeiture).

(3) Optional adjustments to conform with this section for pre-effective-date open periods—(i) General rule. If an employer determined FICA tax liability with respect to section 3121(v)(2) in any period ending before January 1, 2000, for which the applicable period of limitations has not expired on January 1, 2000 (pre-effective-date open periods), in a manner that was not in accordance with this section, the employer may adjust its FICA tax determination for that period to conform to this section. Thus, if an amount deferred was taken into account in a pre-effective-date open period when it was not required to be taken into account (e.g., an amount taken into account before it became reasonably ascertainable), the employer may claim a refund or credit for any FICA tax paid on that amount to the extent permitted by sections 6402, 6413, and 6511.

(ii) Consistency required. In the case of a plan that is not a nonqualified deferred compensation plan (within the meaning of paragraph (b)(1) of this section), if any payment was actually or constructively paid to an employee under the plan in a pre-effective-date open period and that payment was not included in FICA wages by reason of the employer's treatment of the plan as a nonqualified deferred compensation plan, then the employer may claim a refund or credit for FICA tax paid on amounts treated as amounts deferred under the plan (in accordance with the employer's treatment of the plan as a nonqualified deferred compensation plan) for that employee for pre-effective-date open periods only to the extent that the FICA tax paid on all amounts treated as amounts deferred for the employee in all pre-effective-date open periods under the plan exceeds the FICA tax that would have been due on the benefits actually or constructively paid to the employee in those periods under the plan if those benefits were included in FICA wages when paid. If any benefit payments attributable to amounts deferred after December 31, 1993, were actually or constructively paid to an employee under a nonqualified deferred compensation plan (within the meaning of paragraph (b)(1) of this section) in a pre-effective-date open period, but these payments were treated as subject to FICA tax because the employer treated the plan as not being a nonqualified deferred compensation plan, then the employer may claim a refund or credit for the FICA tax paid on those benefit payments only to the extent that the FICA tax paid on those benefit payments exceeds the FICA tax that would have been due on the amounts deferred to which those benefit payments are attributable if those amounts deferred had been taken into account when they would have been required to have been taken into account under this section (if this section had been in effect then).

(iii) Reporting. Any employer that adjusts its FICA tax determination in accordance with paragraphs (g)(3)(i) and (ii) of this section must make appropriate adjustments on Form 941 and Form 941c for the affected periods, and, in addition, must file and furnish Form W-2, or, if applicable, Form W-2c, for any affected employee so that the Social Security Administration may correctly post the amount deferred to the employee's earnings record. The adjustments may be made in accordance with section 6205(a) and the regulations thereunder; however, for purposes of §31.6205-1(b), the error is not required to be treated as ascertained before March 31, 2000.

(4) Application of reasonable, good faith standard—(i) Plans that are not subject to section 3121(v)(2). If a plan is not a nonqualified deferred compensation plan within the meaning of paragraph (b)(1) of this section, but, for a period ending prior to January 1, 2000, and, pursuant to a reasonable, good faith interpretation of section 3121(v)(2), an amount under the plan was taken into account (within the meaning of paragraph (d)(1) of this section) as an amount deferred under a nonqualified deferred compensation plan, then, pursuant to paragraph (g)(2) of this section, the following rules shall apply—

(A) With respect to benefit payments actually or constructively paid before January 1, 2000, that are attributable to amounts previously taken into account under the plan, no additional FICA tax will be due;

(B) On or after January 1, 2000, benefit payments under the plan must be taken into account as wages when actually or constructively paid in accordance with paragraph (a)(1) of this section; and

(C) To the extent permitted by paragraph (g)(3) of this section, the employer may claim a refund or credit for FICA tax actually paid on amounts taken into account prior to January 1, 2000.

(ii) Plans that are subject to section 3121(v)(2) for which the amount deferred has not been fully taken into account—(A) In general. The rules of paragraphs (g)(4)(ii)(B) through (E) of this section apply if a plan is a nonqualified deferred compensation plan (within the meaning of paragraph (b)(1) of this section) and, with respect to an amount deferred under the plan for an employee prior to January 1, 2000, the employer, in accordance with a reasonable, good faith interpretation of section 3121(v)(2), either took into account an amount that is less than the amount that would have been required to be taken into account if paragraphs (a) through (f) of this section had been in effect for that period or took no amount into account. Thus, paragraphs (g)(4)(ii)(B) through (E) of this section apply both to an employer that treated the plan as if it were not a nonqualified deferred compensation plan within the meaning of section 3121(v)(2) (by withholding and paying FICA tax due on benefits actually or constructively paid under the plan during that period, if any) and to an employer that treated the plan as a nonqualified deferred compensation plan within the meaning of section 3121(v)(2).

(B) No additional tax required. Pursuant to paragraph (g)(2) of this section, no additional FICA tax will be due for any period ending prior to January 1, 2000.

(C) General timing rule applicable. In accordance with paragraph (d)(1)(ii) of this section, except as provided in paragraphs (g)(4)(ii) (D) and (E), the general timing rule described in paragraph (a)(1) of this section applies to benefits actually or constructively paid on or after January 1, 2000, attributable to an amount deferred in a period before January 1, 2000, to the extent the amount taken into account was less than the amount that would have been required to be taken into account if paragraphs (a) through (f) of this section had been in effect before January 1, 2000.

(D) Special rule for amounts deferred before 1994. The difference between the amount that was taken into account in any period ending prior to January 1, 1994, and the amount that would have been required or permitted to be taken into account in that period if paragraphs (a) through (f) of this section had been in effect is treated as if it had been taken into account within the meaning of paragraph (d)(1) of this section. For example, in the case of an amount deferred before 1994 that was not reasonably ascertainable (and which was not subject to a substantial risk of forfeiture), the employer is treated as if it had anticipated the actual amount, form, and commencement date for the benefit payments attributable to the amount deferred and had taken the amount deferred into account at an early inclusion date before 1994 using a method permitted under this section. Thus, with respect to such an amount deferred, the employer is not required to take any additional amount into account when the amount deferred becomes reasonably ascertainable, and no additional FICA tax will be due when the benefit payments attributable to the amount deferred are actually or constructively paid.

(E) Special rule for amounts required to be taken into account in 1994 or 1995. In the case of an amount deferred that would have been required to be taken into account in 1994 or 1995 if paragraphs (a) through (f) of this section had been in effect, an employer will be treated as taking the amount deferred into account under paragraph (d)(1) of this section to the extent the employer takes the amount into account by treating it as wages paid by the employer and received by the employee as of any date prior to April 1, 2000.

(iii) Plans that are subject to section 3121(v)(2) for which more than the amount deferred has been taken into account. If a plan is a nonqualified deferred compensation plan (within the meaning of paragraph (b)(1) of this section) and an amount was taken into account under the plan for an employee before January 1, 2000, in accordance with a reasonable, good faith interpretation of section 3121(v)(2), but that amount could not have been taken into account before January 1, 2000, if paragraphs (a) through (f) of this section had been in effect then, the following rules apply—

(A) The determination of the amount deferred for any period beginning on or after January 1, 2000, must be made in accordance with paragraph (c) of this section, and the time when amounts deferred under the plan are required to be taken into account must be determined in accordance with paragraph (e) of this section, without regard to any such amount that was taken into account for any period ending before January 1, 2000; and

(B) To the extent permitted by sections 6402, 6413, and 6511, the employer may claim a refund or credit for an overpayment of tax caused by the overinclusion of wages that occurred before January 1, 2000.

(5) Examples. This paragraph (g) is illustrated by the following examples:
