(a) In general. The excess of an individual's elective deferrals for any taxable year over the applicable limit for the year may not be excluded from gross income under sections 402(a)(8), 402(h)(1)(B), 403(b), 408(k)(6), or 501(c)(18). Thus, an individual's elective deferrals in excess of the applicable limit for a taxable year (that is, the individual's excess deferrals for the year) must be included in gross income for the year, except to the extent the excess deferrals are comprised of designated Roth contributions, and thus, are already includible in gross income. A designated Roth contribution is treated as an excess deferral only to the extent that the total amount of designated Roth contributions for an individual exceeds the applicable limit for the taxable year or the designated Roth contributions are identified as excess deferrals and the individual receives a distribution of the excess deferrals and allocable income under paragraph (e)(2) or (e)(3) of this section.

(b) Elective deferrals. An individual's elective deferrals for a taxable year are the sum of the following:

(1) Any elective contribution under a qualified cash or deferred arrangement (as defined in section 401(k)) to the extent not includible in the individual's gross income for the taxable year on account of section 402(a)(8) (before applying the limits of section 402(g) or this section).

(2) Any employer contribution to a simplified employee pension (as defined in section 408(k)) to the extent not includible in the individual's gross income for the taxable year on account of section 402(h)(1)(B) (before applying the limits of section 402(g) or this section).

(3) Any employer contribution to an annuity contract under section 403(b) under a salary reduction agreement (within the meaning of section 3121(a)(5)(D)) to the extent not includible in the individual's gross income for the taxable year on account of section 403(b) (before applying the limits of section 402(g) or this section).

(4) Any employee contribution designated as deductible under a trust described in section 501(c)(18) to the extent deductible from the individual's income for the taxable year on account of section 501(c)(18) (before appying the limits of section 402(g) or this section). For purposes of this section, the employee contribution is treated as though it were excluded from the individual's gross income.

(5) Any designated Roth contributions described in section 402A (before applying the limits of section 402(g) or this section).

(6) Any elective employer contributions to a SIMPLE retirement account, on behalf of an employee pursuant to a qualified salary reduction arrangement as described in section 408(p)(2) (before applying the limits of section 402(g) or this section).

(c) Certain one-time irrevocable elections. An employer contribution is not treated as an elective deferral under paragraph (b) of this section if the contribution is made pursuant to a one-time irrevocable election made by the employee:

(1) In the case of an annuity contract under section 403(b), at the time of initial eligibility to participate in the salary reduction agreement;

(2) In the case of a qualified cash or deferred arrangement, at a time when, under §1.401(k)-1(a)(3)(v), the election is not treated as a cash or deferred election;

(3) In the case of a trust described in section 501(c)(18), at the time of initial eligibility to have the employer contribute on the employee's behalf to the trust.

(d) Applicable limit—(1) In general. Except as provided under paragraph (d)(2) of this section, the applicable limit for an individual's taxable year is the applicable dollar amount set forth in section 402(g)(1)(B). This applicable dollar amount is increased for the taxable year beginning in 2007 and later years in the same manner as the dollar amount under section 415(b)(1)(A) is adjusted pursuant to section 415(d). See §1.402(g)-2 for the treatment of catch-up contributions described in section 414(v).

(2) Special adjustment for elective deferrals with respect to section 403(b) annuity contracts for certain long-term employees. The applicable limit for an individual who is a qualified employee (as defined in section 402(g)(7)(C)) and has elective deferrals described in paragraph (b)(3) or (5) of this section for a taxable year is adjusted by increasing the applicable limit otherwise determined under paragraph (d)(1) of this section in accordance with section 402(g)(7).

(e) Treatment of excess deferrals—(1) Plan qualification—(i) Effect of excess deferrals. For plan years beginning before January 1, 1988, a plan, annuity contract, simplified employee pension, or trust does not fail to meet the requirements of section 401(a), section 403(b), section 408(k), or section 501(c)(18), respectively, merely because excess deferrals are made with respect to the plan, contract, pension, or trust. For plan years beginning after December 3l, 1987, see section 401(a)(30) and §1.401(a)-30 for the effect of excess deferrals on the qualification of a plan or trust under section 401(a). For purposes of determining whether a plan or trust complies in operation with section 401(a)(30), excess deferrals that are distributed under paragraph (e)(2) or (3) of this section are disregarded. Similar rules apply to annuity contracts under section 403(b), simplified employee pensions under section 408(k), and plans or trusts under section 501(c)(28).

(ii) Treatment of excess deferrals as employer contributions. For other purposes of the Code, including sections 401(a)(4), 401(k)(3), 404, 409, 411, 412, and 416, excess deferrals must be treated as employer contributions even if they are distributed in accordance with paragraph (e)(2) or (3) of this section. However, excess deferrals of a nonhighly compensated employee are not taken into account under section 401(k)(3) (the actual deferral percentage test) to the extent the excess deferrals are prohibited under section 401(a)(30). Excess deferrals are also treated as employer contributions for purposes of section 415 unless distributed under paragraph (e)(2) or (3) of this section.

(iii) Definition of excess deferrals. The term “excess deferrals” means the excess of an individual's elective deferrals for any taxable year, as defined in §1.402(g)-1(b), over the applicable limit under section 402(g)(1) for the taxable year.

(2) Correction of excess deferrals after the taxable year. A plan may provide that if any amount is an excess deferral under paragraph (a) of this section:

(i) Not later than the first April 15 (or such earlier date specified in the plan) following the close of the individual's taxable year, the individual may notify each plan under which elective deferrals were made of the amount of the excess deferrals received by the plan. If any designated Roth contributions were made to a plan, the notification must also identify the extent, if any, to which the excess deferrals are comprised of designated Roth contributions. A plan may provide that an individual is deemed to have notified the plan of excess deferrals (including the portion of excess deferrals that are comprised of designated Roth contributions) to the extent the individual has excess deferrals for the taxable year calculated by taking into account only elective deferrals under the plan and other plans of the same employer and the plan may provide the extent to which such excess deferrals are comprised of designated Roth contributions. A plan may instead provide that the employer may notify the plan on behalf of the individual under these circumstances.

(ii) Not later than the first April 15 following the close of the taxable year, the plan may distribute to the individual the amount designated under paragraph (e)(2)(i) of this section (and any income allocable to that amount).

(3) Correction of excess deferrals during taxable year—(i) A plan may provide that an individual who has excess deferrals for a taxable year may receive a corrective distribution of excess deferrals during the same year. This corrective distribution may be made only if all of the following conditions are satisfied:

(A) The individual designates the distribution as an excess deferral. A plan may provide that an individual is deemed to have designated the distribution to the extent the individual has excess deferrals for the taxable year calculated by taking into account only elective deferrals under the plan and other plans of the same employer. If any designated Roth contributions were made to a plan, the notification must identify the extent to which, if any, the excess deferrals are comprised of designated Roth contributions. A plan may provide that an individual is deemed to have notified the plan of excess deferrals (including the portion of excess deferrals that are comprised of designated Roth contributions) for the taxable year calculated by taking into account only elective deferrals under the plan and other plans of the same employer and the plan may provide the extent to which such excess deferrals are comprised of designated Roth contributions.

(B) The correcting distribution is made after the date on which the plan received the excess deferral.

(C) The plan designates the distribution as a distribution of excess deferrals.

(ii) The provisions of this paragraph (e)(3) are illustrated by the following example:

(4) Plan provisions. In order to distribute excess deferrals pursuant to paragraphs (e)(2) or (e)(3) of this section, a plan must contain language permitting distribution of excess deferrals. A plan may require the notification in paragraphs (e)(2) and (e)(3) of this section to be in writing and may require that the employee certify or otherwise establish that the designated amount is an excess deferral. A plan need not permit distribution of excess deferrals.

(5) Income allocable to excess deferrals—(i) General rule. The income allocable to excess deferrals for a taxable year that begins on or after January 1, 2007 is equal to the sum of the allocable gain or loss for the taxable year of the individual and, to the extent the excess deferrals are or will be credited with gain or loss for the period after the close of the taxable year and prior to the distribution (the gap period) if the total account were to be distributed, the allocable gain or loss during that period. The income allocable to excess deferrals for a taxable year that begins before 2007 is determined using the 1.402(g)-1(e)(5) (as it appeared in the April 1, 2006 edition of 26 CFR Part 1).

(ii) Method of allocating income. A plan may use any reasonable method for computing the income allocable to excess deferrals, provided that the method does not violate section 401(a)(4), is used consistently for all participants and for all corrective distributions under a plan for the plan year, and is used by the plan for allocating income to participants' accounts. See §1.401(a)(4)-1(c)(8). A plan will not fail to use a reasonable method for computing the income allocable to excess deferrals merely because the income allocable to excess deferrals is determined on a date that is no more than 7 days before the distribution.

(iii) Alternative method of allocating taxable year income. A plan may determine the income allocable to excess deferrals for the taxable year by multiplying the income for the taxable year allocable to elective deferrals by a fraction. The numerator of the fraction is the excess deferrals by the employee for the taxable year. The denominator of the fraction is equal to the sum of:

(A) The total account balance of the employee attributable to elective deferrals as of the beginning of the taxable year, plus

(B) The employee's elective deferrals for the taxable year.

(iv) Safe harbor method of allocating gap period income. Under the safe harbor method, income on excess deferrals for the gap period is equal to 10 percent of the income allocable to excess deferrals for the taxable year (calculated under the method described in paragraph (e)(5)(iii) of this section), multiplied by the number of calendar months that have elapsed since the end of the taxable year. For purposes of calculating the number of calendar months that have elapsed under the safe harbor method, a corrective distribution that is made on or before the fifteenth day of the month is treated as made on the last day of the preceding month. A distribution made after the fifteenth day of the month is treated as made on the first day of the next month.

(v) Alternative method for allocating taxable year and gap period income. A plan may determine the allocable gain or loss for the aggregate of the taxable year and the gap period by applying the alternative method provided by paragraph (e)(5)(iii) of this section to this aggregate period. This is accomplished by substituting the income for the taxable year and the gap period for the income for the taxable year and by substituting the elective deferrals for the taxable year and the gap period for the elective deferrals for the taxable year in determining the fraction that is multiplied by that income.

(6) Coordination with distribution or recharacterization of excess contributions. The amount of excess deferrals that may be distributed under this paragraph (e) with respect to an employee for a taxable year is reduced by any excess contributions previously distributed or recharacterized with respect to the employee for the plan year beginning with or within the taxable year. In the event of a reduction under this paragraph (e)(6), the amount of excess contributions includible in the gross income of the employee and reported by the employer as a distribution of excess contributions is reduced by the amount of the reduction under this paragraph (e)(6). See §1.401(k)-2(b)(4)(i). In no case may an individual receive from a plan as a corrective distribution for a taxable year under paragraph (e)(2) or (e)(3) of this section an amount in excess of the individual's total elective deferrals under the plan for the taxable year.

(7) No employee or spousal consent required. A corrective distribution of excess deferrals (and income) may be made under the terms of the plan without regard to any notice or consent otherwise required under sections 411(a)(11) or 417.

(8) Tax treatment—(i) Corrective distributions on or before April 15 after close of taxable year. A corrective distribution of excess deferrals within the period described in paragraph (e)(2) or (e)(3) of this section is excludable from the employee's gross income. However, the income allocable to excess deferrals is includible in the employee's gross income for the taxable year in which the allocable income is distributed. The corrective distribution of excess deferrals (and income) is not subject to the early distribution tax of section 72(t) and is not treated as a distribution for purposes of applying the excise tax under section 4980A.

(ii) Special rule for 1987 and 1988 excess deferrals. Income on excess deferrals for 1987 or 1988 that were timely distributed on or before April 17, 1989, may be reported by the recipient either in the year described in paragraph (e)(8)(i) of this section, or in the year in which the employee would have received the elective deferrals had the employee originally elected to receive the amounts in cash.

(iii) Distributions of excess deferrals after correction period. If excess deferrals (and income) for a taxable year are not distributed within the period described in paragraphs (e)(2) and (e)(3) of this section, they may only be distributed when permitted under section 401(k)(2)(B). These amounts are includible in gross income when distributed, and are treated for purposes of the distribution rules otherwise applicable to the plan as elective deferrals (and income) that were excludable from the individual's gross income under section 402(g). Thus, any amount includible in gross income for any taxable year under this section that is not distributed by April 15 of the following taxable year is not treated as an investment in the contract for purposes of section 72 and is includible in the employee's gross income when distributed from the plan. Excess deferrals that are distributed under this paragraph (e)(8)(iii) are treated as employer contributions for purposes of section 415 when they are contributed to the plan.

(iv) Distributions of excess deferrals from a designated Roth account. The rules of paragraph (e)(8)(iii) of this section generally apply to distributions of excess deferrals that are designated Roth contributions and the attributable income. Thus, if a designated Roth account described in section 402A includes any excess deferrals, any distribution of amounts attributable to those excess deferrals are includible in gross income (without adjustment for any return of investment in the contract under section 72(e)(8)). In addition, such distributions cannot be qualified distributions described in section 402A(d)(2) and are not eligible rollover distributions within the meaning of section 402(c)(4). For this purpose, if a designated Roth account includes any excess deferrals, any distributions from the account are treated as attributable to those excess deferrals until the total amount distributed from the designated Roth account equals the total of such deferrals and attributable income.

(9) No reduction of required minimum distribution. A distribution of excess deferrals (and income) under paragraphs (e)(2) and (e)(3) of this section is not treated as a distribution for purposes of determining whether the plan meets the minimum distribution requirements of section 401(a)(9).

(10) Partial correction. Any distribution under paragraphs (e)(2) or (e)(3) of this section of less than the entire amount of excess deferrals (and income) is treated as a pro rata distribution of excess deferrals and income.

(11) Examples. The provisions of this paragraph are illustrated by the following examples. Assume in Examples 1 and 2 that there is no income or loss allocable to the elective deferrals.

(f) Community property laws. This section is applied without regard to community property laws.

(g) Effective date—(1) In general. Except as otherwise provided, the provisions of this section are effective for taxable years beginning after December 31, 1986.

(2) Deferrals under collective bargaining agreements. In the case of a plan maintained pursuant to one or more collective bargaining agreements between employee representatives and one or more employers ratified before March 1, 1986, the provisions of this section do not apply to contributions made pursuant to the collective bargaining agreement for taxable years beginning before the earlier of January 1, 1989, or the date on which the agreement terminates (determined without regard to any extension thereof after February 28, 1986). These contributions under a collective bargaining agreement are taken into account for purposes of applying this section to elective deferrals under plans not described in this paragraph (g)(2).

(3) Transition rule. For taxable years beginning before January 1, 1992, a plan or an individual may rely on a reasonable interpretation of the rules set forth in section 402(g), as in effect during those years.

(4) Partnership cash or deferred arrangements. For purposes of section 402(g), employer contributions for any plan year beginning after December 31, 1986, and before January 1, 1989, under an arrangement that directly or indirectly permits individual partners to vary the amount of contributions made on their behalf will be treated as elective contributions only if the arrangement was intended to satisfy and did satisfy the nondiscrimination test of section 401(k)(3) and §1.401(k)-1(b) for the plan year.
