Reg. § 1.415(a)-1 General rules with respect to limitations on benefits and contributions under qualified plans.
(a) Trusts Under sections and , a trust that forms part of a pension, profit-sharing, or stock bonus plan will not be qualified under section if any of the following conditions exists:
(1) In the case of a defined benefit plan, the annual benefit with respect to any participant for any limitation year exceeds the limitations of section and .
(2) In the case of a defined contribution plan, the annual additions credited with respect to any participant for any limitation year exceed the limitations of section and .
(3) The trust has been disqualified under section and for any year.
(b) Certain annuities and accounts
(1) In general Under section , an employee annuity plan described in section , an annuity contract described in section , or a simplified employee pension described in section will not be considered to be described in the otherwise applicable section if any of the following conditions exists:
(i) The annual benefit under a defined benefit plan with respect to any participant for any limitation year exceeds the limitations of section and .
(ii) The contributions and other additions credited under a defined contribution plan with respect to any participant for any limitation year exceed the limitations of section and .
(iii) The employee annuity plan, annuity contract, or simplified employee pension has been disqualified under section and for any year.
(2) Special rule for section 403(b) annuity contracts If the contributions and other additions under an annuity contract that otherwise satisfies the requirements of section exceed the limitations of section and with respect to any participant for any limitation year (regardless of whether the annuity contract is a defined contribution plan or a defined benefit plan), then the portion of the contract that includes such excess annual addition fails to be a section annuity contract, and the remaining portion of the contract is a section annuity contract. However, the status of the remaining portion of the contract as a section annuity contract is not retained unless, for the year of the excess and each year thereafter, the issuer of the contract maintains separate accounts for each such portion. In addition, if the benefit under an annuity contract that is a defined benefit plan and that otherwise satisfies the requirements of section exceeds the limitations of section and with respect to any participant for any limitation year, then the contract fails to be a section annuity contract.
(3) Section 403(b) annuity contract For purposes of section and regulations promulgated under section , the term section annuity contract includes arrangements that are treated as annuity contracts for purposes of section . Thus, such term includes custodial accounts described in section and retirement income accounts described in section .

(6) Cross references to special rules for plans maintained by churches For special rules relating to plans maintained by churches as defined in section , see and (providing an exception from the compensation-based limit for participants who have never been a highly compensated employee of the church).
(d) Plan provisions
(1) In general Although no specific plan provision is required under section in order for a plan to establish or maintain its qualification, the plan provisions must preclude the possibility that any distribution under a defined benefit plan or annual addition under a defined contribution plan will exceed the limitations of section . In addition, a defined benefit plan that is subject to the requirements of section must preclude the possibility that any accrual under the plan will exceed the limitations of section . A defined benefit plan may include provisions that automatically freeze or reduce the rate of benefit accrual (or limit the benefit payable in the case of a plan that is not subject to the requirements of section ), and a defined contribution plan may include provisions that automatically limit the annual addition to a level necessary to prevent the limitations of section from being exceeded with respect to any participant. For rules relating to this type of plan provision and the definitely determinable benefit requirement for pension plans, see . Because requires that the operation of such a provision preclude discretion by the employer, if two defined benefit plans that are aggregated under the rules of section would otherwise provide for aggregate benefits that might exceed the limits of section , the plan provisions must specify (without involving employer discretion) how benefits will be limited to prevent a violation of section .
(2) Special rule for profit-sharing and stock bonus plans A provision of a profit-sharing or stock bonus plan that automatically freezes or reduces the amount of annual additions to ensure that the limitations of section will not be exceeded must comply with the requirement set forth in or (as applicable) that such plans provide a definite predetermined formula for allocating the contributions made to the plan among the participants. If the operation of a provision that automatically freezes or reduces the amount of annual additions to ensure that the limitations of section are not exceeded does not involve discretionary action on the part of the employer, the definite predetermined allocation formula requirement is not violated by the provision. If the operation of such a provision involves discretionary action on the part of the employer, the definite predetermined allocation formula requirement is violated. For example, if two profit-sharing plans of one employer otherwise provide for aggregate contributions which may exceed the limits of section , the plan provisions must specify (without involving employer discretion) under which plan contributions and allocations will be reduced to prevent an excess annual addition and how the reduction will occur.
(3) Incorporation by reference
(i) In general A plan is permitted to incorporate by reference the limitations of section , and will not fail to meet the definitely determinable benefit requirement or the definite predetermined allocation formula requirement, whichever applies to the plan, merely because it incorporates the limits of section by reference.
(ii) Section 415 can be applied in more than one manner, but a statutory or regulatory default rule exists Where a provision of section is permitted to be applied in more than one manner but is to be applied in a specified manner in the absence of contrary plan provisions (in other words, a default rule exists), if a plan incorporates the limitations of section by reference with respect to that provision of section and does not specifically vary from the default rule, then the default rule applies. With respect to a provision of section for which a default rule exists, if the limitations of section are to be applied in a manner other than using the default rule, the plan must specify the manner in which the limitation is to be applied in addition to generally incorporating the limitations of section by reference. For example, if a plan generally incorporates the limitations of section by reference and does not restrict the accrued benefits to which the amendments to section made by the Uruguay Round Agreements Act of 1994, Public Law 103-465 (108 Stat. 4809) (GATT), apply (as permitted by Q&A-12 of Rev. Rul. 98-1 (1998-1 CB 249) (see ), which reflects the amendments to section 767 of GATT made by section 1449 of the Small Business Job Protection Act of 1996, Public Law 104-188 (110 Stat. 1755)), then the amendments to section made by GATT apply to all benefits under the plan.
(iii) Section 415 can be applied in more than one manner with no statutory or regulatory default If a limitation of section may be applied in more than one manner, and if there is no governing principle pursuant to which that limitation is applied in the absence of contrary plan provisions, then the plan must specify the manner in which the limitation is to be applied in addition to generally incorporating the limitations of section by reference. For example, if an employer maintains two profit-sharing plans, and if any participant participates in more than one such plan, then both plans must specify (in a consistent manner) under which of the employer's two profit-sharing plans annual additions must be reduced if aggregate annual additions would otherwise exceed the limitations of section .
(iv) Former requirements A plan is not permitted to incorporate by reference formerly applicable requirements of section that are no longer in force (such as the limits of former section ).
(v) Cost-of-living adjustments
(A) In general A plan is permitted to incorporate by reference the annual adjustments to the limitations of section that are made pursuant to section . See for additional rules relating to cost-of-living adjustments under section .
(B) Cost-of-living adjustments not included in accrued benefit until effective Notwithstanding that a plan incorporates the increases to the applicable limits under section by reference, the accrued benefit of a participant for purposes of section and any amount payable to a participant for purposes of are not permitted to reflect increases pursuant to the annual increase under section 415(d) of the dollar limitation described in section or the compensation limit described in section for any period before the annual increase becomes effective. See for rules relating to when the annual adjustments to the dollar and compensation limitations are effective. A plan amendment does not violate the requirements of section merely because it eliminates the incorporation by reference of the increases under section with respect to increases that have not yet occurred.
(C) Application of increase in defined benefit dollar limit to participants who have incurred a severance from employment or commenced receiving benefits If a plan incorporates by reference the annual adjustments to the limitations of section pursuant to this , the plan will be treated as applying the section cost-of-living adjustments to the maximum extent permitted under the safe harbor described in , except to the extent provided in this . Thus, such a plan is not subject to the requirements of (providing special rules for determining the annual benefit of an employee in the case of multiple annuity starting dates) with respect to benefit increases that result solely from an increase in the section limits pursuant to section . If a plan incorporates by reference the annual adjustments to the limitations of section pursuant to this , the annual increase under section 415(d) of the dollar limitation described in section does not apply with respect to a participant if the increase is effective after the participant's severance from employment with the employer maintaining the plan (or, if earlier, after the annuity starting date in the case of a participant who has commenced receiving benefits), unless the plan specifies that this annual increase applies. Similarly, if a plan incorporates by reference the annual adjustments to the limitations of section pursuant to this , the annual increase under section 415(d) of the compensation-based limitation described in section does not apply with respect to a participant for increases that are effective after the participant's severance from employment with the employer maintaining the plan (or, if earlier, after the annuity starting date in the case of a participant who has commenced receiving benefits), unless the plan specifies that this annual increase applies.
(D) Treatment of cost-of-living adjustments for funding and deduction purposes In general, the annual increase under section 415(d) of the dollar limitation described in section and the compensation limitation described in section is treated as a plan amendment, regardless of whether the plan reflects the increase automatically through operation of plan provisions in accordance with this or the plan is amended to reflect the increase (pursuant to ). However, where a plan reflects the annual increase under section 415(d) of the dollar limitation described in section or the compensation limitation described in section automatically through operation of plan provisions pursuant to this , the funding method for the plan is permitted to provide for this annual increase to be treated as an experience loss for purposes of applying sections , , and .
(e) Rules for plans maintained by more than one employer Except as provided in (regarding aggregation of multiemployer plans with plans other than multiemployer plans), for purposes of applying the limitations of section with respect to a participant in a plan maintained by more than one employer, benefits and contributions attributable to such participant from all of the employers maintaining the plan must be taken into account. Furthermore, in applying the limitations of section with respect to a participant in such a plan, the total compensation received by the participant from all of the employers maintaining the plan is taken into account under the plan, unless the plan specifies otherwise.
(f) Special rules
(1) Affiliated employers Pursuant to section and , all employees of all corporations that are members of a controlled group of corporations (within the meaning of section , as modified by section , and determined without regard to section and (e)(3)(C)) are treated as employed by a single employer for purposes of section . Similarly, pursuant to section and regulations promulgated under section , all employees of trades or businesses that are under common control are treated as employed by a single employer. Thus, any defined benefit plan or defined contribution plan maintained by any member of a controlled group of corporations (within the meaning of section ) or by any trade or business (whether or not incorporated) that is part of a group of trades or businesses that are under common control (within the meaning of section ) is deemed maintained by all such members or such trades or businesses. Pursuant to section , for purposes of section , sections and are applied by using the phrase “more than 50 percent” instead of the phrase “at least 80 percent” each place the latter phrase appears in section and in the regulations under section (except for purposes of determining whether two or more organizations are a brother-sister group of trades or businesses under common control under the rules in ).
(2) Affiliated service groups Any defined benefit plan or defined contribution plan maintained by any member of an affiliated service group (within the meaning of section ) is deemed maintained by all members of that affiliated service group.
(3) Leased employees
(i) In general Pursuant to section , except as provided in of this section, with respect to any person (referred to as the recipient) for whom a leased employee (within the meaning of section ) performs services, the leased employee is treated as an employee of the recipient, but contributions or benefits provided by the leasing organization that are attributable to services performed for the recipient are treated as provided under a plan maintained by the recipient.
(ii) Exception for leased employees covered by safe harbor plans Pursuant to section , the rule of of this section does not apply to a leased employee with respect to services performed for a recipient if—
(A) The leased employee is covered by a plan that is maintained by the leasing organization and that meets the requirements of section ; and
(B) Leased employees (determined without regard to this ) do not constitute more than 20 percent of the recipient's nonhighly compensated workforce.
(4) Permissive service credit under governmental plans See section for rules regarding the application of the limitations of sections and (c) where a participant makes contributions (including a transfer described in section or section ) to a defined benefit governmental plan to purchase permissive service credit under the plan.
(5) Definition of severance from employment
(i) General rule For purposes of this section and , , , , , , , and , whether an employee has a severance from employment with the employer that maintains a plan is determined in the same manner as under except that, for purposes of determining the employer of an employee, the modifications provided under section (described in of this section) to the employer aggregation rules apply. Thus, an employee has a severance from employment when the employee ceases to be an employee of the employer maintaining the plan, and an employee does not have a severance from employment if, in connection with a change of employment, the employee's new employer maintains such plan with respect to the employee. The determination of whether an employee ceases to be an employee of the employer maintaining the plan is based on all of the relevant facts and circumstances.
(ii) Multiemployer plans A participant in a multiemployer plan (within the meaning of section ) is not treated as having incurred a severance from employment with the employer maintaining the multiemployer plan for purposes of this section and , , , , , , , and if the participant continues to be an employee of another employer maintaining the multiemployer plan.
(6) Qualified domestic relations orders A benefit provided to an alternate payee (as defined in section ) of a participant pursuant to a qualified domestic relations order (as defined in section ) is treated as if it were provided to the participant for purposes of applying the limitations of section . See .
(7) Effect on other requirements Except as provided in , the application of section does not relieve a plan from the obligation to satisfy other applicable qualification requirements. Accordingly, the terms of the plan must provide for the plan to satisfy section as well as all other applicable requirements. For example, if a defined benefit plan has a normal retirement age of 62, and if a participant's benefit remains unchanged between the ages of 62 and 65 because of the application of the section dollar limit, the plan satisfies the requirements of section only if the plan either commences distribution of the participant's benefit at normal retirement age (without regard to severance from employment) or provides for a suspension of benefits at normal retirement age that satisfies the requirements of section and 29 CFR 2530.203-3. Similarly, if the increase to a participant's benefit under a defined benefit plan in a year after the participant has attained normal retirement age is less than the actuarial increase to the participant's previously accrued benefit because of the application of the section compensation limitation (which is not adjusted for commencement after age 65), the plan satisfies the requirements of section only if the plan either commences distribution of the participant's benefit at normal retirement age (without regard to severance from employment) or provides for a suspension of benefits at normal retirement age that satisfies the requirements of section and 29 CFR 2530.203-3.
(g) Effective date
(1) General rule Except as otherwise provided, this section and , , , , , , and apply to limitation years beginning on or after July 1, 2007.
(2) Governmental plans In the case of a governmental plan as defined in section , this section and , , , , , , and apply to limitation years that begin more than 90 days after the close of the first regular legislative session of the legislative body with authority to amend the plan that begins on or after July 1, 2007. A governmental plan is permitted to apply the provisions of this section and , , , , , , and to limitation years beginning on or after July 1, 2007, provided the plan applies all the applicable provisions of this section and , , , , , , and for such limitation years.
(3) Option to apply regulations earlier A plan may apply the rules in regarding post-severance compensation payments for limitation years prior to the effective date described in and of this section. This early application affects the rules relating to the definition of compensation in and .
(4) Grandfather rule for preexisting benefits A defined benefit plan is considered to satisfy the limitations of section for a participant with respect to benefits accrued or payable under the plan as of the end of the limitation year that is immediately prior to the effective date of final regulations under this section and , , , , , , and (as provided under or of this section) pursuant to plan provisions (including plan provisions relating to the plan's limitation year) that were both adopted and in effect before April 5, 2007, but only if such plan provisions meet the applicable requirements of statutory provisions, regulations, and other published guidance relating to section in effect immediately before the effective date of final regulations under this section and , , , , , , and (as provided under or of this section). Plan provisions will not be treated as failing to satisfy these requirements merely because the plan has not been amended to reflect changes to section made by the Pension Funding Equity Act of 2004, Public Law 108-218 (118 Stat. 596), and the Pension Protection Act of 2006, Public Law 109-280 (120 Stat. 780). In addition, plan provisions will not be treated as failing to satisfy these requirements merely because the plan's definition of compensation for a limitation year that is used for purposes of applying the limitations of section reflects compensation for a plan year that is in excess of the limitation under section that applies to that plan year. If benefits under a plan are accrued after the applicable effective date under or of this section, then the sum of the benefits grandfathered under the first sentence of this and benefits accrued after the applicable effective date must satisfy the requirements of section , taking into account the requirements of this section and , , , , , , and .
(5) Special effective date applies for plan years ending on or after May 4, 2026.
