1.401(k)-1—Certain cash or deferred arrangements.

(a) General rules— (1) Certain plans permitted to include cash or deferred arrangements. A plan, other than a profit-sharing, stock bonus, pre-ERISA money purchase pension, or rural cooperative plan, does not satisfy the requirements of section 401(a) if the plan includes a cash or deferred arrangement. A profit-sharing, stock bonus, pre-ERISA money purchase pension, or rural cooperative plan does not fail to satisfy the requirements of section 401(a) merely because the plan includes a cash or deferred arrangement. A cash or deferred arrangement is part of a plan for purposes of this section if any contributions to the plan, or accruals or other benefits under the plan, are made or provided pursuant to the cash or deferred arrangement.
(2) Rules applicable to cash or deferred arrangements generally— (i) Definition of cash or deferred arrangement. Except as provided in paragraphs (a)(2)(ii) and (iii) of this section, a cash or deferred arrangement is an arrangement under which an eligible employee may make a cash or deferred election with respect to contributions to, or accruals or other benefits under, a plan that is intended to satisfy the requirements of section 401(a) (including a contract that is intended to satisfy the requirements of section 403(a) ).
(ii) Treatment of after-tax employee contributions. A cash or deferred arrangement does not include an arrangement under which amounts contributed under a plan at an employee's election are designated or treated at the time of contribution as after-tax employee contributions (e.g., by treating the contributions as taxable income subject to applicable withholding requirements). See also section 414(h)(1). A designated Roth contribution, however, is not treated as an after-tax contribution for purposes of this section, § 1.401(k)-2 through § 1.401(k)-6 and § 1.401(m)-1 through § 1.401(m)-5. A contribution can be an after-tax employee contribution under the rule of this paragraph (a)(2)(ii) even if the employee's election to make after-tax employee contributions is made before the amounts subject to the election are currently available to the employee.
(iii) Treatment of ESOP dividend election. A cash or deferred arrangement does not include an arrangement under an ESOP under which dividends are either distributed or invested pursuant to an election made by participants or their beneficiaries in accordance with section 404(k)(2)(A)(iii).
(iv) Treatment of elective contributions as plan assets. The extent to which elective contributions constitute plan assets for purposes of the prohibited transaction provisions of section 4975 and Title I of the Employee Retirement Income Security Act of 1974 (88 Stat. 829), Public Law 93-406, is determined in accordance with regulations and rulings issued by the Department of Labor. See 29 CFR 2510.3-102.
(3) Rules applicable to cash or deferred elections generally— (i) Definition of cash or deferred election. A cash or deferred election is any direct or indirect election (or modification of an earlier election) by an employee to have the employer either—
(A) Provide an amount to the employee in the form of cash (or some other taxable benefit) that is not currently available; or
(B) Contribute an amount to a trust, or provide an accrual or other benefit, under a plan deferring the receipt of compensation.
(ii) Automatic enrollment. For purposes of determining whether an election is a cash or deferred election, it is irrelevant whether the default that applies in the absence of an affirmative election is described in paragraph (a)(3)(i)(A) of this section (i.e., the employee receives an amount in cash or some other taxable benefit) or in paragraph (a)(3)(i)(B) of this section (i.e., the employer contributes an amount to a trust or provides an accrual or other benefit under a plan deferring the receipt of compensation).
(iii) Rules related to timing— (A) Requirement that amounts not be currently available. A cash or deferred election can only be made with respect to an amount that is not currently available to the employee on the date of the election. Further, a cash or deferred election can only be made with respect to amounts that would (but for the cash or deferred election) become currently available after the later of the date on which the employer adopts the cash or deferred arrangement or the date on which the arrangement first becomes effective.
(B) Contribution may not precede election. A contribution is made pursuant to a cash or deferred election only if the contribution is made after the election is made.
(C) Contribution may not precede services— (1) General rule. Contributions are made pursuant to a cash or deferred election only if the contributions are made after the employee's performance of service with respect to which the contributions are made (or when the cash or other taxable benefit would be currently available, if earlier).
(2) Exception for bona fide administrative considerations. The timing of contributions will not be treated as failing to satisfy the requirements of this paragraph (a)(3)(iii)(C) merely because contributions for a pay period are occasionally made before the services with respect to that pay period are performed, provided the contributions are made early in order to accommodate bona fide administrative considerations (for example, the temporary absence of the bookkeeper with responsibility to transmit contributions to the plan) and are not paid early with a principal purpose of accelerating deductions.
(iv) Current availability defined. Cash or another taxable benefit is currently available to the employee if it has been paid to the employee or if the employee is able currently to receive the cash or other taxable benefit at the employee's discretion. An amount is not currently available to an employee if there is a significant limitation or restriction on the employee's right to receive the amount currently. Similarly, an amount is not currently available as of a date if the employee may under no circumstances receive the amount before a particular time in the future. The determination of whether an amount is currently available to an employee does not depend on whether it has been constructively received by the employee for purposes of section 451.
(v) Certain one-time elections not treated as cash or deferred elections. A cash or deferred election does not include a one-time irrevocable election made no later than the employee's first becoming eligible under the plan or any other plan or arrangement of the employer that is described in section 219(g)(5)(A) (whether or not such other plan or arrangement has terminated), to have contributions equal to a specified amount or percentage of the employee's compensation (including no amount of compensation) made by the employer on the employee's behalf to the plan and a specified amount or percentage of the employee's compensation (including no amount of compensation) divided among all other plans or arrangements of the employer (including plans or arrangements not yet established) for the duration of the employee's employment with the employer, or in the case of a defined benefit plan to receive accruals or other benefits (including no benefits) under such plans. Thus, for example, employer contributions made pursuant to a one-time irrevocable election described in this paragraph are not treated as having been made pursuant to a cash or deferred election and are not includible in an employee's gross income by reason of § 1.402(a)-1(d). In the case of an irrevocable election made on or before December 23, 1994—
(A) The election does not fail to be treated as a one-time irrevocable election under this paragraph (a)(3)(v) merely because an employee was previously eligible under another plan of the employer (whether or not such other plan has terminated); and
(B) In the case of a plan in which partners may participate, the election does not fail to be treated as a one-time irrevocable election under this paragraph (a)(3)(v) merely because the election was made after commencement of employment or after the employee's first becoming eligible under any plan of the employer, provided that the election was made before the first day of the first plan year beginning after December 31, 1988, or, if later, March 31, 1989.
(vi) Tax treatment of employees. An amount generally is includible in an employee's gross income for the taxable year in which the employee actually or constructively receives the amount. But for section 402(e)(3), an employee is treated as having received an amount that is contributed to an exempt trust or plan described in section 401(a) or 403(a) pursuant to the employee's cash or deferred election. This is the case even if the election to defer is made before the year in which the amount is earned, or before the amount is currently available. See § 1.402(a)-1(d).
(vii) Examples. The following examples illustrate the application of this paragraph (a)(3):

Code of Federal Regulations

Example 1. (i) An employer maintains a profit-sharing plan under which each eligible employee has an election to defer an annual bonus payable on January 30 each year. The bonus equals 10% of compensation during the previous calendar year. Deferred amounts are not treated as after-tax employee contributions. The bonus is currently available on January 30. (ii) An election made prior to January 30 to defer all or part of the bonus is a cash or deferred election, and the bonus deferral arrangement is a cash or deferred arrangement.

Code of Federal Regulations

Example 2. (i) An employer maintains a profit-sharing plan which provides for discretionary profit sharing contributions and under which each eligible employee may elect to reduce his compensation by up to 10% and to have the employer contribute such amount to the plan. The employer pays each employee every two weeks for services during the immediately preceding two weeks. The employee's election to defer compensation for a payroll period must be made prior to the date the amount would otherwise be paid. The employer contributes to the plan the amount of compensation that each employee elected to defer, at the time it would otherwise be paid to the employee, and does not treat the contribution as an after-tax employee contribution.
Code of Federal Regulations 311
(ii) The election is a cash or deferred election and the contributions are elective contributions.

Code of Federal Regulations

Example 3. (i) The facts are the same as in Example 2, except that the employer makes a $10,000 contribution on January 31 of the plan year that is in addition to the contributions that satisfy the employer's obligation to make contributions with respect to cash or deferred elections for prior payroll periods. Employee A makes an election on February 15 to defer $2,000 from compensation that is not currently available and the employer reduces the employee's compensation to reflect the election. (ii) None of the additional $10,000 contributed January 31 is a contribution made pursuant to Employee A's cash or deferred election, because the contribution was made before the election was made. Accordingly, the employer must make an additional contribution of $2,000 in order to satisfy its obligation to contribute an amount to the plan pursuant to Employee A's election. The $10,000 contribution may be allocated under the plan terms providing for discretionary profit sharing contributions.

Code of Federal Regulations

Example 4. (i) The facts are the same as in Example 3, except that Employee A had an outstanding election to defer $500 from each payroll period's compensation. The $10,000 additional payment that is contributed early is not made early in order to accommodate bona fide administrative considerations. (ii) None of the additional $10,000 contributed January 31 is a contribution made pursuant to Employee A's cash or deferred election for future payroll periods, because the contribution was made before the earlier of Employee A's performance of services to which the contribution is attributable or when the compensation would be currently available. Furthermore, the exception for early contributions in paragraph (a)(3)(iii)(C)(2) of this section does not apply. Accordingly, the employer must make an additional contribution of $500 per payroll period in order to satisfy its obligation to contribute an amount to the plan pursuant to Employee A's election. The $10,000 contribution may be allocated under the plan terms providing for discretionary profit sharing contributions.

Code of Federal Regulations

Example 5. (i) Employer B establishes a money purchase pension plan in 1986. This is the first qualified plan established by Employer B. All salaried employees are eligible to participate under the plan. Hourly-paid employees are not eligible to participate under the plan. In 2000, Employer B establishes a profit-sharing plan under which all employees (both salaried and hourly) are eligible. Employer B permits all employees on the effective date of the profit-sharing plan to make a one-time irrevocable election to have Employer B contribute 5% of compensation on their behalf to the plan and make no other contribution to any other plan of Employer B (including plans not yet established) for the duration of the employee's employment with Employer B, and have their salaries reduced by 5%. (ii) The election provided under the profit-sharing plan is not a one-time irrevocable election within the meaning of paragraph (a)(3)(v) of this section with respect to the salaried employees of Employer B who, before becoming eligible to participate under the profit-sharing plan, became eligible to participate under the money purchase pension plan. The election under the profit-sharing plan is a one-time irrevocable election within the meaning of paragraph (a)(3)(v) of this section with respect to the hourly employees, because they were not previously eligible to participate under another plan of the employer.
(4) Rules applicable to qualified cash or deferred arrangements— (i) Definition of qualified cash or deferred arrangement. A qualified cash or deferred arrangement is a cash or deferred arrangement that satisfies the requirements of paragraphs (b), (c), (d), and (e) of this section.
(ii) Treatment of elective contributions as employer contributions. Except as otherwise provided in § 1.401(k)-2(b)(3), elective contributions under a qualified cash or deferred arrangement (including designated Roth contributions) are treated as employer contributions. Thus, for example, elective contributions under such an arrangement are treated as employer contributions for purposes of sections 401(a), 401(k), 402, 404, 409, 411, 412, 415, 416, and 417.
(iii) Tax treatment of employees. Except as provided in section 402(g), 402A (effective for taxable years beginning after December 31, 2005), or § 1.401(k)-2(b)(3), elective contributions under a qualified cash or deferred arrangement are neither includible in an employee's gross income at the time the cash would have been includible in the employee's gross income (but for the cash or deferred election), nor at the time the elective contributions are contributed to the plan. See § 1.402(a)-1(d)(2)(i).
(iv) Application of nondiscrimination requirements to plan that includes a qualified cash or deferred arrangement— (A) Exclusive means of amounts testing. Elective contributions (including elective contributions that are designated Roth contributions) under a qualified cash or deferred arrangement satisfy the requirements of section 401(a)(4) with respect to amounts if and only if the amount of elective contributions satisfies the nondiscrimination test of section 401(k) under paragraph (b)(1) of this section. See § 1.401(a)(4)-1(b)(2)(ii)(B).
(B) Testing benefits, rights and features. A plan that includes a qualified cash or deferred arrangement must satisfy the requirements of section 401(a)(4) with respect to benefits, rights and features in addition to the requirements regarding amounts described in paragraph (a)(4)(iv)(A) of this section. For example, the right to make each level of elective contributions under a cash or deferred arrangement and the right to make designated Roth contributions are rights or features subject to the requirements of section 401(a)(4). See § 1.401(a)(4)-4(e)(3)(i) and (iii)(D). Thus, for example, if all employees are eligible to make a stated level of elective contributions under a cash or deferred arrangement, but that level of contributions can only be made from compensation in excess of a stated amount, such as the Social Security taxable wage base, the arrangement will generally favor HCEs with respect to the availability of elective contributions and thus will generally not satisfy the requirements of section 401(a)(4).
(C) Minimum coverage requirement. A qualified cash or deferred arrangement is treated as a separate plan that must satisfy the requirements of section 410(b). See § 1.410(b)-7(c)(1) for special rules. The determination of whether a cash or deferred arrangement satisfies the requirements of section 410(b) must be made without regard to the modifications to the disaggregation rules set forth in paragraph (b)(4)(v) of this section. See also § 1.401(a)(4)-1 1(g)(3)(vii)(A), relating to corrective amendments that may be made to satisfy the minimum coverage requirements of section 410(b).
(5) Rules applicable to nonqualified cash or deferred arrangements— (i) Definition of nonqualified cash or deferred arrangement. A nonqualified cash or deferred arrangement is a cash or deferred arrangement that fails to satisfy one or more of the requirements in paragraph (b), (c), (d) or (e) of this section.
(ii) Treatment of elective contributions as nonelective contributions. Except as specifically provided otherwise, elective contributions under a nonqualified cash or deferred arrangement are treated as nonelective employer contributions. Thus, for example, the elective contributions under such an arrangement are treated as nonelective employer contributions for purposes of sections 401(a) (including section 401(a)(4)) and 401(k), 404, 409, 411, 412, 415, 416, and 417 and are not subject to the requirements of section 401(m).
(iii) Tax treatment of employees. Elective contributions under a nonqualified cash or deferred arrangement are includible in an employee's gross income at the time the cash or other taxable amount that the employee would have received (but for the cash or deferred election) would have been includible in the employee's gross income. See § 1.402(a)-1(d)(1).
(iv) Qualification of plan that includes a nonqualified cash or deferred arrangement— (A) In general. A profit-sharing, stock bonus, pre-ERISA money purchase pension, or rural cooperative plan does not fail to satisfy the requirements of section 401(a) merely because the plan includes a nonqualified cash or deferred arrangement. In determining whether the plan satisfies the requirements of section 401(a)(4), the nondiscrimination tests of sections 401(k), paragraph (b)(1) of this section, section 401(m)(2) and § 1.401(m)-1(b) may not be used. See §§ 1.401(a)(4)-1(b)(2)(ii)(B) and 1.410(b)-9 (definition of section 401(k) plan).
(B) Application of The amount of employer contributions under a nonqualified cash or deferred arrangement is treated as satisfying section 401(a)(4) if the arrangement is part of a collectively bargained plan that automatically satisfies the requirements of section 410(b). See §§ 1.401(a)(4) -(c)(5) and 1.410(b)-2(b)(7). Additionally, the requirements of sections 401(a)(4) and 410(b) do not apply to a governmental plan (within the meaning of section 414(d)) maintained by a State or local government or political subdivision thereof (or agency or instrumentality thereof). See sections 401(a)(5) and 410(c)(1)(A).
(v) Example. The following example illustrates the application of this paragraph (a)(5):

Code of Federal Regulations

Example. (i) For the 2006 plan year, Employer A maintains a collectively bargained plan that includes a cash or deferred arrangement. Employer contributions under the cash or deferred arrangement do not satisfy the nondiscrimination test of section 401(k) and paragraph (b) of this section. (ii) The arrangement is a nonqualified cash or deferred arrangement. The employer contributions under the cash or deferred arrangement are considered to be nondiscriminatory under section 401(a)(4), and the elective contributions are generally treated as employer contributions under paragraph (a)(5)(ii) of this section. Under paragraph (a)(5)(iii) of this section and under § 1.402(a)-1(d)(1) , however, the elective contributions are includible in each employee's gross income.
(6) Rules applicable to cash or deferred arrangements of self-employed individuals— (i) Application of general rules. Generally, a partnership or sole proprietorship is permitted to maintain a cash or deferred arrangement, and individual partners or owners are permitted to make cash or deferred elections with respect to compensation attributable to services rendered to the entity, under the same rules that apply to other cash or deferred arrangements. For example, any contributions made on behalf of an individual partner or owner pursuant to a cash or deferred arrangement of a partnership or sole proprietorship are elective contributions unless they are designated or treated as after-tax employee contributions. In the case of a partnership, a cash or deferred arrangement includes any arrangement that directly or indirectly permits individual partners to vary the amount of contributions made on their behalf. Consistent with § 1.402(a)-1(d), the elective contributions under such an arrangement are includible in income and are not deductible under section 404(a) unless the arrangement is a qualified cash or deferred arrangement (i.e., the requirements of section 401(k) and this section are satisfied). Also, even if the arrangement is a qualified cash or deferred arrangement, the elective contributions are includible in gross income and are not deductible under section 404(a) to the extent they exceed the applicable limit under section 402(g). See also § 1.401(a)-3 0.
(ii) Treatment of matching contributions made on behalf of self-employed individuals. Under section 402(g)(8), matching contributions made on behalf of a self-employed individual are not treated as elective contributions made pursuant to a cash or deferred election, without regard to whether such matching contributions indirectly permit individual partners to vary the amount of contributions made on their behalf.
(iii) Timing of self-employed individual's cash or deferred election. For purposes of paragraph (a)(3)(iv) of this section, a partner's compensation is deemed currently available on the last day of the partnership taxable year and a sole proprietor's compensation is deemed currently available on the last day of the individual's taxable year. Accordingly, a self-employed individual may not make a cash or deferred election with respect to compensation for a partnership or sole proprietorship taxable year after the last day of that year. See § 1.401(k)-2(a)(4)(ii) for the rules regarding when these contributions are treated as allocated.
(iv) Special rule for certain payments to self-employed individuals. For purposes of sections 401(k) and 401(m), the earned income of a self-employed individual for a taxable year constitutes payment for services during that year. Thus, for example, if a partnership provides for cash advance payments during the taxable year to be made to a partner based on the value of the partner's services prior to the date of payment (and which do not exceed a reasonable estimate of the partner's earned income for the taxable year), a contribution of a portion of these payments to a profit sharing plan in accordance with an election to defer the portion of the advance payments does not fail to be made pursuant to a cash or deferred election within the meaning of paragraph (a)(3)(iii) of this section merely because the contribution is made before the amount of the partner's earned income is finally determined and reported. However, see § 1.401(k)-2(a)(4)(ii) for rules on when earned income is treated as received.
(b) Coverage and nondiscrimination requirements— (1) In general. A cash or deferred arrangement satisfies this paragraph (b) for a plan year only if—
(i) The group of eligible employees under the cash or deferred arrangement (including any employees taken into account for purposes of section 410(b) pursuant to § 1.401(a)(4)-1 1(g)(3)(vii)(A)) satisfies the requirements of section 410(b) (including the average benefit percentage test, if applicable); and
(ii) The cash or deferred arrangement satisfies—
(A) The ADP test of section 401(k)(3) described in § 1.401(k)-2 ;
(B) The ADP safe harbor provisions of section 401(k)(12) described in § 1.401(k)-3; or
(C) The ADP safe harbor provisions of section 401(k)(13) described in § 1.401(k)-3; or
(D) The SIMPLE 401(k) provisions of section 401(k)(11) described in § 1.401(k)-4.
(2) Automatic satisfaction by certain plans. Notwithstanding paragraph (b)(1) of this section, a governmental plan (within the meaning of section 414(d)) maintained by a State or local government or political subdivision thereof (or agency or instrumentality thereof) shall be treated as meeting the requirements of this paragraph (b).
(3) Anti-abuse provisions. This section and §§ 1.401(k)-2 through 1.401(k)-6 are designed to provide simple, practical rules that accommodate legitimate plan changes. At the same time, the rules are intended to be applied by employers in a manner that does not make use of changes in plan testing procedures or other plan provisions to inflate inappropriately the ADP for NHCEs (which is used as a benchmark for testing the ADP for HCEs) or to otherwise manipulate the nondiscrimination testing requirements of this paragraph (b). Further, this paragraph (b) is part of the overall requirement that benefits or contributions not discriminate in favor of HCEs. Therefore, a plan will not be treated as satisfying the requirements of this paragraph (b) if there are repeated changes to plan testing procedures or plan provisions that have the effect of distorting the ADP so as to increase significantly the permitted ADP for HCEs, or otherwise manipulate the nondiscrimination rules of this paragraph, if a principal purpose of the changes was to achieve such a result.
(4) Aggregation and restructuring— (i) In general. This paragraph (b)(4) contains the exclusive rules for aggregating and disaggregating plans and cash or deferred arrangements for purposes of this section, and §§ 1.401(k)-2 through 1.401(k)-6.
(ii) Aggregation of cash or deferred arrangements within a plan. Except as otherwise specifically provided in this paragraph (b)(4), all cash or deferred arrangements included in a plan are treated as a single cash or deferred arrangement and a plan must apply a single test under paragraph (b)(1)(ii) of this section with respect to all such arrangements within the plan. Thus, for example, if two groups of employees are eligible for separate cash or deferred arrangements under the same plan, all contributions under both cash or deferred arrangements must be treated as made under a single cash or deferred arrangement subject to a single test, even if they have significantly different features, such as different limits on elective contributions.
(iii) Aggregation of plans— (A) In general. For purposes of this section and §§ 1.401(k)-2 through 1.401(k)-6, the term plan means a plan within the meaning of § 1.410(b)-7(a) and (b), after application of the mandatory disaggregation rules of § 1.410(b)-7(c), and the permissive aggregation rules of § 1.410(b)-7(d), as modified by paragraph (b)(4)(v) of this section. Thus, for example, two plans (within the meaning of § 1.410(b)-7(b)) that are treated as a single plan pursuant to the permissive aggregation rules of § 1.410(b)-7(d) are treated as a single plan for purposes of sections 401(k) and (m).
(B) Plans with inconsistent ADP testing methods. Pursuant to paragraph (b)(4)(ii) of this section, a single testing method must apply with respect to all cash or deferred arrangements under a plan. Thus, in applying the permissive aggregation rules of § 1.410(b)-7(d), an employer may not aggregate plans (within the meaning of § 1.410(b)-7(b)) that apply inconsistent testing methods. For example, a plan (within the meaning of § 1.410(b)-7(b)) that applies the current year testing method may not be aggregated with another plan that applies the prior year testing method. Similarly, an employer may not aggregate a plan (within the meaning of § 1.410(b)-7(b)) using the ADP safe harbor provisions of section 401(k)(12) and another plan that is using the ADP test of section 401(k)(3).
(iv) Disaggregation of plans and separate testing— (A) In general. If a cash or deferred arrangement is included in a plan (within the meaning of § 1.410(b)-7(b)) that is mandatorily disaggregated under the rules of section 410(b) (as modified by this paragraph (b)(4)), the cash or deferred arrangement must be disaggregated in a consistent manner. For example, in the case of an employer that is treated as operating qualified separate lines of business under section 414(r), if the eligible employees under a cash or deferred arrangement are in more than one qualified separate line of business, only those employees within each qualified separate line of business may be taken into account in determining whether each disaggregated portion of the plan complies with the requirements of section 401(k), unless the employer is applying the special rule for employer-wide plans in § 1.414(r)-1(c)(2)(ii) with respect to the plan. Similarly, if a cash or deferred arrangement under which employees are permitted to participate before they have completed the minimum age and service requirements of section 410(a)(1) applies section 410(b)(4)(B) for determining whether the plan complies with section 410(b)(1), then the arrangement must be treated as two separate arrangements, one comprising all eligible employees who have met the age and service requirements of section 410(a)(1) and one comprising all eligible employees who have not met the age and service requirements under section 410(a)(1), unless the plan is using the rule in § 1.401(k)-2(a)(1)(iii)(A).
(B) Restructuring prohibited. Restructuring under § 1.401(a)(4)-9(c) may not be used to demonstrate compliance with the requirements of section 401(k). See § 1.401(a)(4)-9(c)(3)(ii).
(v) Modifications to (A) Certain disaggregation rules not applicable. The mandatory disaggregation rules relating to section 401(k) plans and section 401(m) plans set forth in § 1.410(b)-7(c)(1) and ESOP and non-ESOP portions of a plan set forth in § 1.410(b)-7(c)(2) shall not apply for purposes of this section and §§ 1.401(k)-2 through 1.401(k)-6. Accordingly, notwithstanding § 1.410(b)-7(d)(2), an ESOP and a non-ESOP which are different plans (within the meaning of section 414(l), as described in § 1.410(b)-7(b)) are permitted to be aggregated for these purposes.
(B) Permissive aggregation of collective bargaining units. Notwithstanding the general rule under section 410(b) and § 1.410(b)-7(c) that a plan that benefits employees who are included in a unit of employees covered by a collective bargaining agreement and employees who are not included in the collective bargaining unit is treated as comprising separate plans, an employer can treat two or more separate collective bargaining units as a single collective bargaining unit for purposes of this section and §§ 1.401(k)-2 through 1.401(k)-6, provided that the combinations of units are determined on a basis that is reasonable and reasonably consistent from year to year. Thus, for example, if a plan benefits employees in three categories (e.g., employees included in collective bargaining unit A, employees included in collective bargaining unit B, and employees who are not included in any collective bargaining unit), the plan can be treated as comprising three separate plans, each of which benefits only one category of employees. However, if collective bargaining units A and B are treated as a single collective bargaining unit, the plan will be treated as comprising only two separate plans, one benefiting all employees who are included in a collective bargaining unit and another benefiting all other employees. Similarly, if a plan benefits only employees who are included in collective bargaining unit A and employees who are included in collective bargaining unit B, the plan can be treated as comprising two separate plans. However, if collective bargaining units A and B are treated as a single collective bargaining unit, the plan will be treated as a single plan. An employee is treated as included in a unit of employees covered by a collective bargaining agreement if and only if the employee is a collectively bargained employee within the meaning of § 1.410(b)-6(d)(2).
(C) Multiemployer plans. Notwithstanding § 1.410(b)-7(c)(4)(ii)(C), the portion of the plan that is maintained pursuant to a collective bargaining agreement (within the meaning of § 1.413-1(a)(2)) is treated as a single plan maintained by a single employer that employs all the employees benefiting under the same benefit computation formula and covered pursuant to that collective bargaining agreement. The rules of paragraph (b)(4)(v)(B) of this section (including the permissive aggregation of collective bargaining units) apply to the resulting deemed single plan in the same manner as they would to a single employer plan, except that the plan administrator is substituted for the employer where appropriate and that appropriate fiduciary obligations are taken into account. The noncollectively bargained portion of the plan is treated as maintained by one or more employers, depending on whether the noncollectively bargaining unit employees who benefit under the plan are employed by one or more employers.
(vi) Examples. The following examples illustrate the application of this paragraph (b)(4):

Code of Federal Regulations

Example 1. (i) Employer A maintains Plan V, a profit-sharing plan that includes a cash or deferred arrangement in which all of the employees of Employer A are eligible to participate. For purposes of applying section 410(b), Employer A is treated as operating qualified separate lines of business under section 414(r) in accordance with § 1.414(r)-1(b) . However, Employer A applies the special rule for employer-wide plans in § 1.414(r)-1(c)(2)(ii) to the portion of its profit-sharing plan that consists of elective contributions under the cash or deferred arrangement (and to no other plans or portions of plans). (ii) Under these facts, the requirements of this section and §§ 1.401(k)-2 through 1.401(k)-6 must be applied on an employer-wide rather than a qualified separate line of business basis.

Code of Federal Regulations

Example 2. (i) Employer B maintains Plan W, a profit-sharing plan that includes a cash or deferred arrangement in which all of the employees of Employer B are eligible to participate. For purposes of applying section 410(b), the plan treats the cash or deferred arrangement as two separate plans, one for the employees who have completed the minimum age and service eligibility conditions under section 410(a)(1) and the other for employees who have not completed the conditions. The plan provides that it will satisfy the section 401(k) safe harbor requirement of § 1.401(k)-3 with respect to the employees who have met the minimum age and service conditions and that it will meet the ADP test requirements of § 1.401(k)-2 with respect to the employees who have not met the minimum age and service conditions. (ii) Under these facts, the cash or deferred arrangement must be disaggregated on a consistent basis with the disaggregation of Plan W. Thus, the requirements of § 1.401(k)-2 must be applied by comparing the ADP for eligible HCEs who have not completed the minimum age and service conditions with the ADP for eligible NHCEs for the applicable year who have not completed the minimum age and service conditions.

Code of Federal Regulations

Example 3. (i) Employer C maintains Plan X, a stock-bonus plan including an ESOP. The plan also includes a cash or deferred arrangement for participants in the ESOP and non-ESOP portions of the plan. (ii) Pursuant to paragraph (b)(4)(v)(A) of this section the ESOP and non-ESOP portions of the stock-bonus plan are a single cash or deferred arrangement for purposes of this section and §§ 1.401(k)-2 through 1.401(k)-6. However, as provided in paragraph (a)(4)(iv)(C) of this section, the ESOP and non-ESOP portions of the plan are still treated as separate plans for purposes of satisfying the requirements of section 410(b).
(c) Nonforfeitability requirements— (1) General rule. A cash or deferred arrangement satisfies this paragraph (c) only if the amount attributable to an employee's elective contributions are immediately nonforfeitable, within the meaning of paragraph (c)(2) of this section, are disregarded for purposes of applying section 411(a)(2) to other contributions or benefits, and the contributions remain nonforfeitable even if the employee makes no additional elective contributions under a cash or deferred arrangement.
(2) Definition of immediately nonforfeitable. An amount is immediately nonforfeitable if it is immediately nonforfeitable within the meaning of section 411, and would be nonforfeitable under the plan regardless of the age and service of the employee or whether the employee is employed on a specific date. An amount that is subject to forfeitures or suspensions permitted by section 411(a)(3) does not satisfy the requirements of this paragraph (c).
(3) Example. The following example illustrates the application of this paragraph (c):

Code of Federal Regulations

Example. (i) Employees B and C are covered by Employer Y's stock bonus plan, which includes a cash or deferred arrangement. All employees participating in the plan have a nonforfeitable right to a percentage of their account balance derived from all contributions (including elective contributions) as shown in the following table:
Years of service Nonforfeitablepercentage
Less than 1 0
1 20
2 40
3 60
4 80
5 or more 100
(ii) The cash or deferred arrangement does not satisfy paragraph (c) of this section because elective contributions are not immediately nonforfeitable. Thus, the cash or deferred arrangement is a nonqualified cash or deferred arrangement.
(d) Distribution limitation— (1) General rule. A cash or deferred arrangement satisfies this paragraph (d) only if amounts attributable to elective contributions may not be distributed before one of the following events, and any distributions so permitted also satisfy the additional requirements of paragraphs (d)(2) through (5) of this section (to the extent applicable)—
(i) The employee's death, disability, or severance from employment;
(ii) In the case of a profit-sharing, stock bonus or rural cooperative plan, the employee's attainment of age 59 1/2, or the employee's hardship; or
(iii) The termination of the plan.
(2) Rules applicable to distributions upon severance from employment. An employee has a severance from employment when the employee ceases to be an employee of the employer maintaining the plan. 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. For example, a new employer maintains a plan with respect to an employee by continuing or assuming sponsorship of the plan or by accepting a transfer of plan assets and liabilities (within the meaning of section 414(l)) with respect to the employee.
(3) Rules applicable to hardship distributions— (i) Distribution must be on account of hardship. A distribution is treated as made after an employee's hardship for purposes of paragraph (d)(1)(ii) of this section if and only if it is made on account of the hardship. For purposes of this rule, a distribution is made on account of hardship only if the distribution both is made on account of an immediate and heavy financial need of the employee and is necessary to satisfy the financial need. The determination of the existence of an immediate and heavy financial need and of the amount necessary to meet the need must be made in accordance with nondiscriminatory and objective standards set forth in the plan.
(ii) Limit on maximum distributable amount— (A) General rule. A distribution on account of hardship mus
