(a) Disqualification of plans
(1) In general. Under section 415(g) and this section, with respect to a particular limitation year, a plan (and the trust forming part of the plan) is disqualified in accordance with the rules provided in paragraph (b) of this section, if the conditions described in paragraph (a)(2) or (a)(3) of this section apply. For purposes of this paragraph (a), the determination of whether a plan or a group of aggregated plans exceeds the limitations imposed by section 415 for a particular limitation year is, except as otherwise provided, made by taking into account the aggregation of plan rules provided in section 415(f) and § 1.414(f)-1.
(2) Defined contribution plans. A plan is disqualified in accordance with the rules provided in paragraph (b) of this section if annual additions (as defined in § 1.415(c)-1(b)) with respect to the account of any participant in a defined contribution plan maintained by the employer exceed the limitations of section 415(c) and § 1.415(c)-1.
(3) Defined benefit plans. A plan is disqualified in accordance with the rules provided in paragraph (b) of this section if the annual benefit (as defined in § 1.415(b)-1(b)(1)) of a participant in a defined benefit plan maintained by the employer exceeds the limitations of section 415(b) and § 1.415(b)-1.
(b) Rules for disqualification of plans and trusts
(1) In general. If any plan (including a trust which forms part of such plan) is disqualified for a particular limitation year under the rules set forth in this paragraph (b), then the disqualification is effective as of the first day of the first plan year containing any portion of the particular limitation year.
(2) Single plan. In the case of a single qualified defined benefit plan (determined without regard to section 415(f) and § 1.415(f)-1) maintained by the employer that provides an annual benefit (as defined in § 1.415(b)-1(b)(1)) in excess of the limitations of section 415(b) and § 1.415(b)-1 for any particular limitation year, such plan is disqualified in that limitation year. Similarly, if the employer only maintains a single defined contribution plan (determined without regard to section 415(f) and § 1.415(f)-1) under which annual additions (as defined in § 1.415(c)-1(b)) allocated to the account of any participant exceed the limitations of section 415(c) and § 1.415(c)-1 for any particular limitation year, such plan is also disqualified in that limitation year.
(3) Multiple plans
(i) In general. If the limitations of section 415(b) and § 1.415(b)-1, or section 415(c) and § 1.415(c)-1, are exceeded for a particular limitation year with respect to any participant solely because of the application of the aggregation rules of section 415(f)(1) and § 1.415(f)-1 (taking into account the rules of § 1.415(a)-1(f)), then one or more of the plans is disqualified in accordance with the ordering rules set forth in paragraph (b)(3)(ii) of this section, applied in accordance with the rules of application set forth in paragraph (b)(3)(iii) of this section, subject to the special rules set forth in paragraph (b)(3)(iv) of this section, until, without regard to annual benefits or annual additions under the disqualified plan or plans, the remaining plans satisfy the applicable limitations of section 415.
(ii) Ordering rules
(A) Disqualification of ongoing plans other than multiemployer plans. If there are two or more plans that have not been terminated at any time including the last day of the particular limitation year, and if one or more of those plans is a multiemployer plan described in section 414(f), then one or more of the plans (as needed to satisfy the limitations of section 415) that has not been terminated and is not a multiemployer plan is disqualified in that limitation year. For purposes of the preceding sentence, the determination of whether a plan is a multiemployer plan described in section 414(f) is made as of the last day of the particular limitation year.
(B) Disqualification of ongoing multiemployer plans. If, after the application of paragraph (b)(3)(ii)(A) of this section, there are two or more plans and one or more of the plans has been terminated at any time including the last day of the particular limitation year, then one or more of the plans (as needed to satisfy the applicable limitations of section 415) that has not been so terminated (regardless of whether the plan is a multiemployer plan described in section 414(f)) is disqualified in that limitation year.
(iii) Rules of application
(A) Employer elects which plan is disqualified. If there are two or more plans of an employer within a group of plans one or more of which is to be disqualified pursuant to paragraph (b)(3)(ii)(A) or (B) of this section, then the employer may elect, in a manner determined by the Commissioner, which plan or plans are disqualified. If those two or more plans are involved because of the application of § 1.415(a)-1(f), the employers involved may elect, in a manner determined by the Commissioner, which plan or plans are disqualified. However, the election described in the preceding sentence is not effective unless made by all of those employers.
(B) Commissioner determines which plan is disqualified. If the election described in paragraph (b)(3)(iii)(A) of this section is not made with respect to the two plans described in paragraph (b)(3)(iii)(A) of this section, then the Commissioner, taking into account all of the facts and circumstances, has the discretion to determine the plan that is disqualified in the particular limitation year. In making this determination, some of the factors that will be taken into account include, but are not limited to, the number of participants in each plan, the amount of benefits provided on an overall basis by each plan, and the extent to which benefits are distributed or retained in each plan.
(iv) Special rules
(A) Simplified employee pensions. If there are two or more plans one or more of which is to be disqualified pursuant to paragraph (b)(3)(ii)(A) or (B) of this section, and if one of the plans is a simplified employee pension (as defined in section 408(k)), then the simplified employee pension is not disqualified until all of the other plans have been disqualified. However, if one of the plans has been terminated, then the simplified employee pension is disqualified before the terminated plan. For purposes of this paragraph (b)(3)(iv)(A), the disqualification of a simplified employee pension means that the simplified employee pension is no longer described under section 408(k).
(B) Aggregating medical accounts with defined contribution plans. In the event that aggregating a medical account described in § 1.415(c)-1(a)(2)(ii)(C) or (D) and a defined contribution plan other than such a medical account causes the limitations of section 415(c) and § 1.415(c)-1 applicable to a participant to be exceeded for a particular limitation year, the defined contribution plan other than the medical account is disqualified for the limitation year.
(C) Aggregating section 403(b) annuity contract and qualified defined contribution plan
(1) In general. In the event that aggregating a section 403(b) annuity contract and a qualified defined contribution plan under the provisions of section 415(f)(1)(B) causes the limitations of section 415(c) and § 1.415(c)-1 applicable to a participant under the aggregated defined contribution plans to be exceeded for a particular limitation year, the excess of the contributions to the annuity contract plus the annual additions to the qualified plan over such limitations is attributed to the annuity contract and therefore includable in the gross income of the participant for the taxable year with or within which that limitation year ends. See § 1.415(a)-1(b)(2) for rules regarding the treatment of a contribution to a section 403(b) annuity contract that exceeds the limitations of section 415.
(2) Example. The following example illustrates the application of this paragraph (b)(3)(iv)(C). It is assumed for purposes of this example that the dollar limitation under section 415(c)(1)(A) that applies for all relevant limitation years is $45,000. The example is as follows:
Example.

(i) N is employed by a hospital which purchases an annuity contract described in section 403(b) on N's behalf for the current limitation year. N is also the 100 percent owner of a professional corporation P that maintains a qualified defined contribution plan during the current limitation year in which N participates. (The facts of this example are the same as in § 1.415(f)-1(j) Example 7.) N's compensation (within the meaning of § 1.415(c)-2) from the hospital for the current limitation year is $150,000. For the current limitation year, the hospital contributes $30,000 for the section 403(b) annuity contract on N's behalf, which is within the limitations applicable to N under the annuity contract (specifically, the limit under the annuity contract is $45,000)). Professional corporation P also contributes $20,000 to the qualified defined contribution plan on N's behalf for the current limitation year (which represents the only annual additions allocated to N's account under the plan for such year), which is within the $45,000 limitation of section 415(c)(1) applicable to N under the plan.

(ii) Under section 415(k)(4), the professional corporation, as well as N, is considered to maintain the annuity contract. Accordingly, the sum of the annual additions under the qualified defined contribution plan maintained by professional corporation P and the annuity contract must satisfy the limitations of section 415(c) and § 1.415(c)-1.

(iii) Because the total aggregate contributions ($50,000) exceed the section 415(c) limitation applicable to N ($45,000), $5,000 of the $30,000 contributed to the section 403(b) annuity contract is considered an excess contribution and therefore currently includable in N's gross income. The contract continues to be a section 403(b) annuity contract only if, for the current limitation year and all years thereafter, the issuer of the contract maintains separate accounts for each portion attributable to such excess contributions. See §§ 1.415(a)-1(b)(2).

(c) Plan year for certain annuity contracts and individual retirement plans. For purposes of this section, unless the plan under which the annuity contract or individual retirement plan is provided specifies that a different twelve-month period is considered to be the plan year—
(1) An annuity contract described in section 403(b) is considered to have a plan year coinciding with the taxable year of the individual on whose behalf the contract has been purchased; and
(2) A simplified employee pension described in section 408(k) is considered to have a plan year coinciding with the year under the plan that is used pursuant to section 408(k)(7)(C).
