(a) General definition. Except as otherwise provided in this section, compensation from the employer within the meaning of section 415(c)(3), which is used for purposes of section 415 and regulations promulgated under section 415, means all items of remuneration described in paragraph (b) of this section, but excludes the items of remuneration described in paragraph (c) of this section. Paragraph (d) of this section provides safe harbor definitions of compensation that are permitted to be provided in a plan in lieu of the generally applicable definition of compensation. Paragraph (e) of this section provides timing rules relating to compensation. Paragraph (f) of this section provides rules regarding the application of the rules of section 401(a)(17) to the definition of compensation for purposes of section 415. Paragraph (g) of this section provides special rules relating to the determination of compensation, including rules for determining compensation for a section 403(b) annuity contract, rules for determining the compensation of employees of controlled groups or affiliated service groups, rules for disabled employees, rules relating to foreign compensation, rules regarding deemed section 125 compensation, rules for employees in qualified military service, and rules relating to back pay.

(b) Items includible as compensation. For purposes of applying the limitations of section 415, except as otherwise provided in this section, the term compensation means remuneration for services of the following types—

(1) The employee's wages, salaries, fees for professional services, and other amounts received (without regard to whether or not an amount is paid in cash) for personal services actually rendered in the course of employment with the employer maintaining the plan, to the extent that the amounts are includible in gross income (or to the extent amounts would have been received and includible in gross income but for an election under section 125(a), 132(f)(4), 402(e)(3), 402(h)(1)(B), 402(k), or 457(b)). These amounts include, but are not limited to, commissions paid to salespersons, compensation for services on the basis of a percentage of profits, commissions on insurance premiums, tips, bonuses, fringe benefits, and reimbursements or other expense allowances under a nonaccountable plan as described in §1.62-2(c).

(2) In the case of an employee who is an employee within the meaning of section 401(c)(1) and regulations promulgated under section 401(c)(1), the employee's earned income (as described in section 401(c)(2) and regulations promulgated under section 401(c)(2)), plus amounts deferred at the election of the employee that would be includible in gross income but for the rules of section 402(e)(3), 402(h)(1)(B), 402(k), or 457(b).

(3) Amounts described in section 104(a)(3), 105(a), or 105(h), but only to the extent that these amounts are includible in the gross income of the employee.

(4) Amounts paid or reimbursed by the employer for moving expenses incurred by an employee, but only to the extent that at the time of the payment it is reasonable to believe that these amounts are not deductible by the employee under section 217.

(5) The value of a nonstatutory option (which is an option other than a statutory option as defined in §1.421-1(b)) granted to an employee by the employer, but only to the extent that the value of the option is includible in the gross income of the employee for the taxable year in which granted.

(6) The amount includible in the gross income of an employee upon making the election described in section 83(b).

(7) Amounts that are includible in the gross income of an employee under the rules of section 409A or section 457(f)(1)(A) or because the amounts are constructively received by the employee.

(c) Items not includible as compensation. The term compensation does not include—

(1) Contributions (other than elective contributions described in section 402(e)(3), section 408(k)(6), section 408(p)(2)(A)(i), or section 457(b)) made by the employer to a plan of deferred compensation (including a simplified employee pension described in section 408(k) or a simple retirement account described in section 408(p), and whether or not qualified) to the extent that the contributions are not includible in the gross income of the employee for the taxable year in which contributed. In addition, any distributions from a plan of deferred compensation (whether or not qualified) are not considered as compensation for section 415 purposes, regardless of whether such amounts are includible in the gross income of the employee when distributed. However, if the plan so provides, any amounts received by an employee pursuant to a nonqualified unfunded deferred compensation plan are permitted to be considered as compensation for section 415 purposes in the year the amounts are actually received, but only to the extent such amounts are includible in the employee's gross income.

(2) Amounts realized from the exercise of a nonstatutory option (which is an option other than a statutory option as defined in §1.421-1(b)), or when restricted stock or other property held by an employee either becomes freely transferable or is no longer subject to a substantial risk of forfeiture (see section 83 and regulations promulgated under section 83).

(3) Amounts realized from the sale, exchange, or other disposition of stock acquired under a statutory stock option (as defined in §1.421-1(b)).

(4) Other amounts that receive special tax benefits, such as premiums for group-term life insurance (but only to the extent that the premiums are not includible in the gross income of the employee and are not salary reduction amounts that are described in section 125).

(5) Other items of remuneration that are similar to any of the items listed in paragraphs (c)(1) through (c)(4) of this section.

(d) Safe harbor rules with respect to plan's definition of compensation—(1) In general. Paragraphs (d)(2) through (4) of this section contain safe harbor definitions of compensation that are automatically considered to satisfy section 415(c)(3) if specified in the plan. The Commissioner may, in revenue rulings, notices, and other guidance of general applicability published in the Internal Revenue Bulletin (see §601.601(d)(2) of this chapter), provide additional definitions of compensation that are treated as satisfying section 415(c)(3).

(2) Simplified compensation. The safe harbor definition of compensation under this paragraph (d)(2) includes only those items specified in paragraph (b)(1) or (2) of this section and excludes all those items listed in paragraph (c) of this section.

(3) Section 3401(a) wages. The safe harbor definition of compensation under this paragraph (d)(3) includes wages within the meaning of section 3401(a) (for purposes of income tax withholding at the source), plus amounts that would be included in wages but for an election under section 125(a), 132(f)(4), 402(e)(3), 402(h)(1)(B), 402(k), or 457(b). However, any rules that limit the remuneration included in wages based on the nature or location of the employment or the services performed (such as the exception for agricultural labor in section 3401(a)(2)) are disregarded for this purpose.

(4) Information required to be reported under sections 6041, 6051 and 6052. The safe harbor definition of compensation under this paragraph (d)(4) includes amounts that are compensation under the safe harbor definition of paragraph (d)(3) of this section, plus all other payments of compensation to an employee by his employer (in the course of the employer's trade or business) for which the employer is required to furnish the employee a written statement under sections 6041(d), 6051(a)(3), and 6052. See §§1.6041-1(a), 1.6041-2(a)(1), 1.6052-1, and 1.6052-2, and also see §31.6051-1(a)(1)(i)(C) of this chapter. This safe harbor definition of compensation may be modified to exclude amounts paid or reimbursed by the employer for moving expenses incurred by an employee, but only to the extent that, at the time of the payment, it is reasonable to believe that these amounts are deductible by the employee under section 217.

(e) Timing rules—(1) In general—(i) Payment during the limitation year. Except as otherwise provided in this paragraph (e), in order to be taken into account for a limitation year, compensation within the meaning of section 415(c)(3) must be actually paid or made available to an employee (or, if earlier, includible in the gross income of the employee) within the limitation year. For this purpose, compensation is treated as paid on a date if it is actually paid on that date or it would have been paid on that date but for an election under section 125, 132(f)(4), 401(k), 403(b), 408(k), 408(p)(2)(A)(i), or 457(b).

(ii) Payment prior to severance from employment. Except as otherwise provided in this paragraph (e), in order to be taken into account for a limitation year, compensation within the meaning of section 415(c)(3) must be paid or treated as paid to the employee (in accordance with the rules of paragraph (e)(1)(i) of this section) prior to the employee's severance from employment with the employer maintaining the plan. See §1.415(a)-1(f)(5) for the definition of severance from employment.

(2) Certain minor timing differences. Notwithstanding the provisions of paragraph (e)(1)(i) of this section, a plan may provide that compensation for a limitation year includes amounts earned during that limitation year but not paid during that limitation year solely because of the timing of pay periods and pay dates if—

(i) These amounts are paid during the first few weeks of the next limitation year;

(ii) The amounts are included on a uniform and consistent basis with respect to all similarly situated employees; and

(iii) No compensation is included in more than one limitation year.

(3) Compensation paid after severance from employment—(i) In general. Any compensation described in paragraph (e)(3)(ii) of this section does not fail to be compensation (within the meaning of section 415(c)(3)) pursuant to the rule of paragraph (e)(1)(ii) of this section merely because it is paid after the employee's severance from employment with the employer maintaining the plan, provided the compensation is paid by the later of 21⁄2 months after severance from employment with the employer maintaining the plan or the end of the limitation year that includes the date of severance from employment with the employer maintaining the plan. In addition, the plan may provide that amounts described in paragraph (e)(3)(iii) of this section are included in compensation (within the meaning of section 415(c)(3)) if—

(A) Those amounts are paid by the later of 21⁄2 months after severance from employment with the employer maintaining the plan or the end of the limitation year that includes the date of severance from employment with the employer maintaining the plan; and

(B) Those amounts would have been included in the definition of compensation if they were paid prior to the employee's severance from employment with the employer maintaining the plan.

(ii) Regular pay after severance from employment. An amount is described in this paragraph (e)(3)(ii) if—

(A) The payment is regular compensation for services during the employee's regular working hours, or compensation for services outside the employee's regular working hours (such as overtime or shift differential), commissions, bonuses, or other similar payments; and

(B) The payment would have been paid to the employee prior to a severance from employment if the employee had continued in employment with the employer.

(iii) Leave cashouts and deferred compensation. An amount is described in this paragraph (e)(3)(iii) if the amount is either—

(A) Payment for unused accrued bona fide sick, vacation, or other leave, but only if the employee would have been able to use the leave if employment had continued; or

(B) Received by an employee pursuant to a nonqualified unfunded deferred compensation plan, but only if the payment would have been paid to the employee at the same time if the employee had continued in employment with the employer and only to the extent that the payment is includible in the employee's gross income.

(iv) Other post-severance payments. Any payment that is not described in paragraph (e)(3)(ii) or (iii) of this section is not considered compensation under paragraph (e)(3)(i) of this section if paid after severance from employment with the employer maintaining the plan, even if it is paid within the time period described in paragraph (e)(3)(i) of this section. Thus, compensation does not include severance pay, or parachute payments within the meaning of section 280G(b)(2), if they are paid after severance from employment with the employer maintaining the plan, and does not include post-severance payments under a nonqualified unfunded deferred compensation plan unless the payments would have been paid at that time without regard to the severance from employment.

(4) Salary continuation payments for military service and disabled participants. The rule of paragraph (e)(1)(ii) of this section does not apply to payments to an individual who does not currently perform services for the employer by reason of qualified military service (as that term is used in section 414(u)(1)) to the extent those payments do not exceed the amounts the individual would have received if the individual had continued to perform services for the employer rather than entering qualified military service, but only if the plan so provides. In addition, the rule of paragraph (e)(1)(ii) of this section does not apply to compensation paid to a participant who is permanently and totally disabled (as defined in section 22(e)(3)) if the conditions set forth in paragraph (g)(4)(ii)(A) of this section are satisfied (applied by substituting a continuation of compensation for the continuation of contributions), but only if the plan so provides.

(5) Special rule for governmental plans. For purposes of applying the rules of paragraph (e)(3) of this section, a governmental plan (as defined in section 414(d)) may provide for the substitution of the calendar year in which the severance from employment with the employer maintaining the plan occurs for the limitation year in which the severance from employment with the employer maintaining the plan occurs.

(6) Examples. The provisions of this paragraph (e) are illustrated by the following examples:

(f) Interaction with section 401(a)(17). Because a plan may not base allocations (in the case of a defined contribution plan) or benefits (in the case of a defined benefit plan) on compensation in excess of the limitation under section 401(a)(17), a plan's definition of compensation for a year that is used for purposes of applying the limitations of section 415 is not permitted to reflect compensation for a year that is in excess of the limitation under section 401(a)(17) that applies to that year. See §§1.401(a)(17)-1(a)(3)(i) and 1.401(a)(17)-1(b)(3)(ii) for rules regarding the effective date of increases in the section 401(a)(17) compensation limitation for a plan year and for a 12-month period other than the plan year.

(g) Special rules—(1) Compensation for section 403(b) annuity contract. In the case of an annuity contract described in section 403(b), the term participant's compensation means the participant's includible compensation determined under section 403(b)(3). Accordingly, the rules for determining a participant's compensation pursuant to section 415(c)(3) (other than section 415(c)(3)(E)) and this section do not apply to a section 403(b) annuity contract.

(2) Employees of controlled groups of corporations, etc. In the case of an employee of two or more corporations which are members of a controlled group of corporations (as defined in section 414(b) as modified by section 415(h)), the term compensation for such employee includes compensation from all employers that are members of the group, regardless of whether the employee's particular employer has a qualified plan. This special rule is also applicable to an employee of two or more trades or businesses (whether or not incorporated) that are under common control (as defined in section 414(c) as modified by section 415(h)), to an employee of two or more members of an affiliated service group as defined in section 414(m), and to an employee of two or more members of any group of employers who must be aggregated and treated as one employer pursuant to section 414(o).

(3) Aggregation of section 403(b) annuity with qualified plan of controlled employer. If a section 403(b) annuity contract is aggregated with a qualified plan of a controlled employer in accordance with §1.415(f)-1(f)(2), then, in applying the limitations of section 415(c) in connection with the aggregation of the section 403(b) annuity with a qualified plan, the total compensation from both employers is permitted to be taken into account.

(4) Permanent and total disability of defined contribution plan participant—(i) In general. Pursuant to section 415(c)(3)(C), if the conditions set forth in paragraph (g)(4)(ii) of this section are satisfied, then, in the case of a participant in any defined contribution plan who is permanently and totally disabled (as defined in section 22(e)(3)), the participant's compensation means the compensation the participant would have received for the year if the participant was paid at the rate of compensation paid immediately before becoming permanently and totally disabled, if such compensation is greater than the participant's compensation determined without regard to this paragraph (g)(4).

(ii) Conditions for deemed disability compensation. The rule of paragraph (g)(4)(i) of this section applies only if the following conditions are satisfied—

(A) Either the participant is not a highly compensated employee (as defined in section 414(q)) immediately before becoming disabled, or the plan provides for the continuation of contributions on behalf of all participants who are permanently and totally disabled for a fixed or determinable period;

(B) The plan provides that the rule of this paragraph (g)(4) (treating certain amounts as compensation for a disabled participant) applies with respect to the participant; and

(C) Contributions made with respect to amounts treated as compensation under this paragraph (g)(4) are nonforfeitable when made.

(5) Foreign compensation, etc.—(i) In general. Amounts paid to an individual as compensation for services do not fail to be treated as compensation under paragraphs (b)(1) and (2) of this section (and are not excluded from the definition of compensation pursuant to paragraph (c)(4) of this section) merely because those amounts are not includible in the individual's gross income on account of the location of the services. Similarly, compensation for services do not fail to be treated as compensation under paragraphs (b)(1) and (2) of this section (and are not excluded from the definition of compensation pursuant to paragraph (c)(4) of this section) merely because those amounts are paid by an employer with respect to which all compensation paid to the participant by such employer is excluded from gross income. Thus, for example, the determination of whether an amount is treated as compensation under paragraph (b)(1) or (2) of this section is made without regard to the exclusions from gross income under sections 872, 893, 894, 911, 931, and 933.

(ii) Exclusion of non-participant compensation by the plan. With respect to a nonresident alien who is not a participant in a plan, the plan may provide that the compensation described in paragraph (g)(5)(i) of this section is not treated as compensation for purposes of paragraphs (b)(1) and (b)(2) of this section to the extent the compensation is excludable from gross income and is not effectively connected with the conduct of a trade or business within the United States, but only if the plan applies this rule uniformly to all such employees. For purposes of this paragraph (g)(5)(ii), nonresident alien has the same meaning as in section 7701(b)(1)(B).

(6) Deemed section 125 compensation—(i) General rule. A plan is permitted to provide that deemed section 125 compensation (as defined in paragraph (g)(6)(ii) of this section) is compensation within the meaning of section 415(c)(3), but only if the plan applies this rule uniformly to all employees with respect to whom amounts subject to section 125 are included in compensation.

(ii) Definition of deemed section 125 compensation. Deemed section 125 compensation is an amount that is excludable from the income of the participant under section 106 that is not available to the participant in cash in lieu of group health coverage under a section 125 arrangement solely because that participant is not able to certify that the participant has other health coverage. Under this definition, amounts are deemed section 125 compensation only if the employer does not otherwise request or collect information regarding the participant's other health coverage as part of the enrollment process for the health plan.

(7) Employees in qualified military service. See section 414(u)(7) for special rules regarding compensation of employees who are in qualified military service within the meaning of section 414(u)(5).

(8) Back pay. Payments awarded by an administrative agency or court or pursuant to a bona fide agreement by an employer to compensate an employee for lost wages are compensation within the meaning of section 415(c)(3) for the limitation year to which the back pay relates, but only to the extent such payments represent wages and compensation that would otherwise be included in compensation under this section.
