Reg. § 1.401(m)-3 Safe harbor requirements.

(1) Section 401(m)(11) safe harbor Matching contributions under a plan satisfy the ACP safe harbor provisions of section 401(m)(11) for a plan year if the plan satisfies the safe harbor contribution requirement of paragraph (b) or (c) of this section for the plan year, the limitations on matching contributions of paragraph (d) of this section, the notice requirement of paragraph (e) of this section, the plan year requirements of paragraph (f) of this section, and the additional rules of paragraphs (g), (h) and (j) of this section, as applicable.

(2) Section 401(m)(12) safe harbor For a plan year beginning on or after January 1, 2008, matching contributions under a plan satisfy the ACP safe harbor provisions of section 401(m)(12) for a plan year if the matching contributions are made with respect to an automatic contribution arrangement described in paragraph § 1.401(k)-3(j) that satisfies the safe harbor requirements of § 1.401(k)-3, the limitations on matching contributions of paragraph (d) of this section, the notice requirement of paragraph (e) of this section, the plan year requirements of paragraph (f) of this section, and the additional rules of paragraphs (g), (h) and (j) of this section, as applicable.

(3) Requirements applicable to safe harbor contributions Pursuant to sections 401(k)(12)(E)(ii) and 401(k)(13)(D)(iv), the safe harbor contribution requirement of paragraph (b) or (c) of this section and § 1.401(k)-3(k) must be satisfied without regard to section 401(l). The contributions made under paragraphs (b) and (c) of this section and § 1.401(k)-3(k) are referred to as safe harbor nonelective contributions and safe harbor matching contributions.

(1) General rule A plan that provides for matching contributions meets the requirements of this section only if it satisfies the limitations on contributions set forth in this paragraph (d).

(2) Matching rate must not increase A plan that provides for matching contributions meets the requirements of this paragraph (d) only if the ratio of matching contributions on behalf of an employee under the plan for a plan year to the employee's elective deferrals and employee contributions, does not increase as the amount of an employee's elective deferrals and employee contributions increases.

(3) Limit on matching contributions A plan that provides for matching contributions satisfies the requirements of this section only if—

(4) Limitation on rate of match A plan meets the requirements of this section only if the ratio of matching contributions on behalf of an HCE to that HCE's elective deferrals or employee contributions (or the sum of elective deferrals and employee contributions) for that plan year is no greater than the ratio of matching contributions to elective deferrals or employee contributions (or the sum of elective deferrals and employee contributions) that would apply with respect to any NHCE for whom the elective deferrals or employee contributions (or the sum of elective deferrals and employee contributions) are the same percentage of safe harbor compensation. An employee is taken into account for purposes of this paragraph (d)(4) if the employee is an eligible employee under the cash or deferred arrangement with respect to which the contributions required by paragraph (b) or (c) of this section are being made for a plan year. A plan will not fail to satisfy this paragraph (d)(4) merely because the plan provides that matching contributions will be made separately with respect to each payroll period (or with respect to all payroll periods ending with or within each month or quarter of a plan year) taken into account under the plan for the plan year, provided that matching contributions with respect to any elective deferrals or employee contributions made during a plan year quarter are contributed to the plan by the last day of the immediately following plan year quarter.

(5) HCEs participating in multiple plans The rules of section 401(m)(2)(B) and § 1.401(m)-2(a)(3)(ii) apply for purposes of determining the rate of matching contributions under paragraph (d)(4) of this section. However, a plan will not fail to satisfy the safe harbor matching contribution requirements of this section merely because an HCE participates during the plan year in more than one plan that provides for matching contributions, provided that—

(6) Permissible restrictions on elective deferrals by NHCEs

(1) General rule Except as provided in this paragraph (f) or in paragraph (g) of this section, a plan will fail to satisfy the requirements of section 401(m)(11), section 401(m)(12), and this section unless plan provisions that satisfy the rules of this section are adopted before the first day of that plan year and remain in effect for an entire 12-month plan year. In addition, except as provided in paragraph (h) of this section or in guidance of general applicability published in the Internal Revenue Bulletin (see § 601.601(d)(2)(ii)(b) of this chapter), a plan which includes provisions that satisfy the rules of this section will not satisfy the requirements of § 1.401(m)-1(b) if it is amended to change such provisions for that plan year. Moreover, if, as described in paragraph (j)(4) of this section, safe harbor matching or nonelective contributions will be made to another plan for a plan year, provisions under that other plan specifying that the safe harbor contributions will be made and providing that the contributions will be QNECs or QMACs must also be adopted before the first day of that plan year.

(2) Initial plan year A newly established plan (other than a successor plan within the meaning of § 1.401(m)-2(c)(2)(iii)) will not be treated as violating the requirements of this paragraph (f) merely because the plan year is less than 12 months, provided that the plan year is at least 3 months long (or, in the case of a newly established employer that establishes the plan as soon as administratively feasible after the employer comes into existence, a shorter period). Similarly, a plan will not fail to satisfy the requirements of this paragraph (f) for the first plan year in which matching contributions are provided under the plan provided that—

(3) Change of plan year A plan that has a short plan year as a result of changing its plan year will not fail to satisfy the requirements of paragraph (f)(1) of this section merely because the plan year has less than 12 months, provided that—

(4) Final plan year A plan that terminates during a plan year will not fail to satisfy the requirements of paragraph (f)(1) of this section merely because the final plan year is less than 12 months, provided that the plan satisfies the requirement of this section through the date of termination and either—

(1) General rule

(2) Supplemental notice The supplemental notice requirement of this paragraph (h)(2) is satisfied if each eligible employee is given a notice that satisfies the requirements of § 1.401(k)-3(g)(2).

(1) Contributions taken into account A contribution is taken into account for purposes of this section for a plan year under the same rules as § 1.401(k)-3(h)(1).

(2) Use of safe harbor nonelective contributions to satisfy other nondiscrimination tests A safe harbor nonelective contribution used to satisfy the nonelective contribution requirement under paragraph (b) of this section may also be taken into account for purposes of determining whether a plan satisfies section 401(a)(4) under the same rules as § 1.401(k)-3(h)(2).

(3) Early participation rules Section 401(m)(5)(C) and § 1.401(m)-2(a)(1)(iii)(A), which provide an alternative nondiscrimination rule for certain plans that provide for early participation, do not apply for purposes of section 401(m)(11), section 401(m)(12), and this section. Thus, a plan is not treated as satisfying this section with respect to the eligible employees who have not completed the minimum age and service requirements of section 410(a)(1)(A) unless the plan satisfies the requirements of this section with respect to such eligible employees.

(4) Satisfying safe harbor contribution requirement under another defined contribution plan Safe harbor matching or nonelective contributions may be made to another defined contribution plan under the same rules as § 1.401(k)-3(h)(4). Consequently, each NHCE under the plan providing for matching contributions must be eligible under the same conditions under the other defined contribution plan and the plan to which the contributions are made must have the same plan year as the plan providing for matching contributions.

(5) Contributions used only once Safe harbor matching or nonelective contributions cannot be used to satisfy the requirements of this section with respect to more than one plan.

(6) Plan must satisfy ACP with respect to employee contributions If the plan provides for employee contributions, in addition to satisfying the requirements of this section, it must also satisfy the ACP test of § 1.401(m)-2. See § 1.401(m)-2(a)(5)(iv) for special rules under which the ACP test is permitted to be performed disregarding some or all matching when this section is satisfied with respect to the matching contributions.
