(2) Plan provision requirement. A plan that provides for employee contributions or matching contributions satisfies this section only if it provides that the nondiscrimination requirements of
section 401(m) will be met. Thus, the plan must provide for satisfaction of one of the specific alternatives described in
paragraph (b)(1) of this section and, if with respect to that alternative there are optional choices, which of the optional choices will apply. For example, a plan that uses the ACP test of
section 401(m)(2), as described in
paragraph (b)(1)(i) of this section, must specify whether it is using the current year testing method or prior year testing method. Additionally, a plan that uses the prior year testing method must specify whether the ACP for eligible NHCEs for the first plan year is 3% or the ACP for the eligible NHCEs for the first plan year. Similarly, a plan that uses the safe harbor method of
section 401(m)(11) or
401(m)(12), as described in paragraphs (b)(1)(ii) and (b)(1)(iii) of this section, must specify the default percentages that apply for the plan year and whether the safe harbor contribution will be the nonelective safe harbor contribution or the matching safe harbor contribution, and is not permitted to provide that ACP testing will be used if the requirements for the safe harbor are not satisfied. For purposes of this paragraph (c)(2), a plan may incorporate by reference the provisions of
section 401(m)(2) and
§ 1.401(m)-2 if that is the nondiscrimination test being applied. The Commissioner may, in guidance of general applicability, published in the Internal Revenue Bulletin (see
§ 601.601(d)(2) of this chapter), specify the options that will apply under the plan if the nondiscrimination test is incorporated by reference in accordance with the preceding sentence.
