Section 1.401(a)-1 - Post-ERISA qualified plans and qualified trusts; in general(a)Introduction - (1)In general. This section and the following regulation sections under section 401 reflect the provisions of section 401 after amendment by the Employee Retirement Income Security Act of 1974 (Pub. L. 93-406 ) ("ERISA").(b)Requirements for pension plans -(1)Definitely determinable benefits.(i) In order for a pension plan to be a qualified plan under section 401(a), the plan must be established and maintained by an employer primarily to provide systematically for the payment of definitely determinable benefits to its employees over a period of years, usually for life, after retirement or attainment of normal retirement age (subject to paragraph (b)(2) of this section). A plan does not fail to satisfy this paragraph (b)(1)(i) merely because the plan provides, in accordance with section 401(a)(36), that a distribution may be made from the plan to an employee who has attained age 62 and who is not separated from employment at the time of such distribution.(ii) Section 1.401-1(b)(1)(i) , a pre-ERISA regulation, provides rules applicable to this requirement, and that regulation is applicable except as otherwise provided.(iii) The use of the type of plan provision described in § 1.415(a)-1(d)(1) which automatically freezes or reduces the rate of benefit accrual or the annual addition to insure that the limitations of section 415 will not be exceeded, will not be considered to violate the requirements of this subparagraph provided that the operation of such provision precludes discretion by the employer.(2)Normal retirement age -(i)General rule. The normal retirement age under a plan must be an age that is not earlier than the earliest age that is reasonably representative of the typical retirement age for the industry in which the covered workforce is employed.(ii)Age 62 safe harbor. A normal retirement age under a plan that is age 62 or later is deemed to be not earlier than the earliest age that is reasonably representative of the typical retirement age for the industry in which the covered workforce is employed.(iii)Age 55 to age 62. In the case of a normal retirement age that is not earlier than age 55 and is earlier than age 62, whether the age is not earlier than the earliest age that is reasonably representative of the typical retirement age for the industry in which the covered workforce is employed is based on all of the relevant facts and circumstances.(iv)Under age 55. A normal retirement age that is lower than age 55 is presumed to be earlier than the earliest age that is reasonably representative of the typical retirement age for the industry in which the covered workforce is employed, unless the Commissioner determines that under the facts and circumstances the normal retirement age is not earlier than the earliest age that is reasonably representative of the typical retirement age for the industry in which the covered workforce is employed.(v)Age 50 safe harbor for qualified public safety employees. A normal retirement age under a plan that is age 50 or later is deemed to be not earlier than the earliest age that is reasonably representative of the typical retirement age for the industry in which the covered workforce is employed if substantially all of the participants in the plan are qualified public safety employees (within the meaning of section 72(t)(10)(B)).(3)Benefit distribution prior to retirement. For purposes of paragraph (b)(1)(i) of this section, retirement does not include a mere reduction in the number of hours that an employee works. Accordingly, benefits may not be distributed prior to normal retirement age solely due to a reduction in the number of hours that an employee works.(4)Effective date. Except as otherwise provided in this paragraph (b)(4), paragraphs (b)(2) and (3) of this section are effective May 22, 2007. In the case of a governmental plan (as defined in section 414(d)), paragraphs (b)(2) and (3) of this section are effective for plan years beginning on or after January 1, 2009. In the case of a plan maintained pursuant to one or more collective bargaining agreements that have been ratified and are in effect on May 22, 2007, paragraphs (b)(2) and (3) of this section do not apply before the first plan year that begins after the last of such agreements terminate determined without regard to any extension thereof (or, if earlier, May 24, 2010. See § 1.411(d)-4 , A-12, for a special transition rule in the case of a plan amendment that increases a plan's normal retirement age pursuant to paragraph (b)(2) of this section.T.D. 7748, 46 FR 1695, Jan. 7, 1981, as amended by T.D. 9319, 72 FR 16894, Apr. 5, 2007; T.D. 9325, 72 FR 28606, May 22, 2007
