§ 1.410(a)-4 Maximum age conditions and time of participation. ( a ) *Maximum age conditions* — ( 1 ) *General rule.* A plan is not a qualified plan (and a trust forming a part of such plan is not a qualified trust) if the plan excludes from participation (on the basis of age) an employee who has attained an age specified by the plan unless— ( i ) The plan is a defined benefit plan or a target benefit plan, and
( ii ) The employee begins employment with the employer after the employee has attained an age specified by the plan, which age is not more than 5 years before normal retirement age (within the meaning of section 411(a)(8) and § 1.411(a)-7. For purposes of this paragraph, a target benefit plan is a defined contribution plan under which the amount of employer contributions allocated to each participant is determined under a plan formula which does not allow employer discretion and on the basis of the amount necessary to provide a target benefit specified by the plan for such participant. Such target benefit must be the type of benefit which is provided by a defined benefit plan and the targeted benefit must not discriminate in favor of employees who are officers, shareholders, or highly compensated. For purposes of this paragraph, in the determination of the time an employee begins employment, any such time which is included in a period of service which may be disregarded under the break in service rules need not be taken into account.
( 2 ) *Examples.* The rules provided by this paragraph are illustrated by the following examples: Example 1. A defined benefit plan provides that an employee will become a participant upon completion of 3 years of service if at such time the employee is less than age 60. The normal retirement age under the plan is age 65. The plan also provides full and immediate vesting for each of the plan's participants. Under the plan, an employee hired at age 58 would be denied participation on account of service for the first 3 years and on account of maximum age for the remaining years even though the employee was hired more than 5 years prior to the normal retirement date. The plan therefore does not satisfy section 410(a)(2).
Example 2. A defined benefit plan provides a normal retirement age of the later of age 65 or completion of 10 years of service. Because no employee could ever be hired within 5 years of his normal retirement age, the plan could not exclude employees for being over a specified age.
Example 3. Prior to the effective date of section 410, a defined benefit plan with a normal retirement age of 65 contained a maximum age 55 requirement for participation. Because of the maximum age requirement, and employee hired at age 58 was excluded from the plan. This employee is age 61 at the time that section 410 first applies to the plan. The employee cannot be excluded from participation because of age. The exclusion under section 410(a)(2) is not applicable in this instance because the employee's age at the time of hire, 58, was not within 5 years of the normal retirement age specified in the plan.
Example 4. Employee A was hired at age 50 and participated in a defined benefit plan until separating from service at age 55 with 5 years of service and with no vested benefit. At age 61, employee A was rehired within 5 years of the normal retirement age of 65 after he incurred 6 consecutive breaks in service. Because A's consecutive number of 1-year breaks (6) exceeds his years of service prior to such breaks (5), his service before the breaks may be disregarded. Consequently, A's initial employment date falling within such period may be disregarded and the plan could exclude A on account of his age because his employment commenced within 5 years of normal retirement age.
( b ) *Time of participation* — ( 1 ) *General rule.* A plan is not a qualified plan (and a trust forming a part of such plan is not a qualified trust) unless under the plan any employee who has satisfied the applicable minimum age and service requirements specified in § 1.410(a)-3, and who is otherwise entitled to participate in the plan, commences participation in the plan no later than the earlier of— ( i ) The first day of the first plan year beginning after the date on which such employee first satisfied such requirements, or
( ii ) The date 6 months after the date on which he first satisfied such requirements, unless such employee was separated from service and has not returned before the date referred to in subdivision (i) or (ii), whichever is applicable. If such separated employee returns to service after either of such dates without incurring a 1-year break in service, the employee must commence participation immediately upon his return. In the case of a plan using the elapsed time method described in § 1.410(a)-7, such an employee who has a period of absence commencing before the date referred to in subdivision (i) or (ii) (whichever is applicable) must commence participation as of such applicable date no later than the date such absence ended. However, if an employee's prior service is disregarded on account of the plan's break-in-service rules then, for purposes of this subparagraph, such service is also disregarded for purposes of determining the date on which such employee first satisfied the minimum age and service requirements.
( 2 ) *Examples.* The rules provided by this paragraph are illustrated by the following examples:
Example 1. A calendar year plan provides that an employee may enter the plan only on the first semi-annual entry date, January 1 or July 1, after he has satisfied the applicable minimum age and service requirements specified in section 410(a)(1). The plan satisfies the requirements of this paragraph because an employee is eligible to participate no later than the earlier of (1) the first day of the first plan year beginning after he satisfied the applicable minimum age and service requirements, or (2) the date 6 months after he satisfied such requirements.
Example 2. A plan provides that an employee is not eligible to participate until the first day of the first plan year beginning after he has satisfied the minimum age and service requirements of section 410(a)(1). In this case, an employee who satisfies the “6 month” rule described in subparagraph (1) of this paragraph will not be eligible to participate in the plan. Therefore, the plan does not satisfy the requirements of this paragraph.
Example 3. A calendar year plan provides that an employee may enter the plan only on the first semi-annual entry date, January 1 or July 1, after he has satisfied the applicable minimum age and service requirements specified in section 410(a)(1). Employee A after 10 years of service separated from service in 1976 with a vested benefit. On February 1, 1990, A returns to employment covered by the plan. Assuming A completes a year of service after his return, A must participate immediately on his return, February 1. A's prior service cannot be disregarded, because he had a vested benefit when he separated from service. Therefore, the plan may not postpone his participation until July 1.
Example 4. Assume the same facts as in example (3). The plan has the break-in-service rule described in section 410(a)(5)(D) and § 1.410(a)-5(c)(4). Employee B, after he had 5 years of service but no vested benefit incurs 5 consecutive 1-year breaks. Because B's prior service can be disregarded, the plan may postpone B's participation in the plan under the rule described in section 410(a)(4) and this paragraph.
