26 U.S.C. § 410
Minimum participation standards
A trust shall not constitute a qualified trust under section 401(a) if the plan of which it is a part excludes from participation (on the basis of age) employees who have attained a specified age.
For purposes of this subsection, the term “year of service” means a 12-month period during which the employee has not less than 1,000 hours of service. For purposes of this paragraph, computation of any 12-month period shall be made with reference to the date on which the employee’s employment commenced, except that, under regulations prescribed by the Secretary of Labor, such computation may be made by reference to the first day of a plan year in the case of an employee who does not complete 1,000 hours of service during the 12-month period beginning on the date his employment commenced.
In the case of any seasonal industry where the customary period of employment is less than 1,000 hours during a calendar year, the term “year of service” shall be such period as may be determined under regulations prescribed by the Secretary of Labor.
For purposes of this subsection, the term “hour of service” means a time of service determined under regulations prescribed by the Secretary of Labor.
For purposes of this subsection, in the case of any maritime industry, 125 days of service shall be treated as 1,000 hours of service. The Secretary of Labor may prescribe regulations to carry out this subparagraph.
Except as otherwise provided in subparagraphs (B), (C), and (D), all years of service with the employer or employers maintaining the plan shall be taken into account in computing the period of service for purposes of paragraph (1).
In the case of any employee who has any 1-year break in service (as defined in section 411(a)(6)(A)) under a plan to which the service requirements of clause (i) of paragraph (1)(B) apply, if such employee has not satisfied such requirements, service before such break shall not be required to be taken into account.
In computing an employee’s period of service for purposes of paragraph (1) in the case of any participant who has any 1-year break in service (as defined in section 411(a)(6)(A)), service before such break shall not be required to be taken into account under the plan until he has completed a year of service (as defined in paragraph (3)) after his return.
If any years of service are not required to be taken into account by reason of a period of breaks in service to which clause (i) applies, such years of service shall not be taken into account in applying clause (i) to a subsequent period of breaks in service.
For purposes of clause (i), the term “nonvested participant” means a participant who does not have any nonforfeitable right under the plan to an accrued benefit derived from employer contributions.
For purposes of this subparagraph, the term “year” means the period used in computations pursuant to paragraph (3).
For purposes of this paragraph, the term “average benefit percentage” means, with respect to any group, the average of the benefit percentages calculated separately with respect to each employee in such group (whether or not a participant in any plan).
The term “benefit percentage” means the employer-provided contribution or benefit of an employee under all qualified plans maintained by the employer, expressed as a percentage of such employee’s compensation (within the meaning of section 414(s)).
For purposes of this paragraph, the term “qualified plan” means any plan which (without regard to this subsection) meets the requirements of section 401(a).
If employees not meeting the minimum age or service requirements of subsection (a)(1) (without regard to subparagraph (B) thereof) are covered under a plan of the employer which meets the requirements of paragraph (1) separately with respect to such employees, such employees may be excluded from consideration in determining whether any plan of the employer meets the requirements of paragraph (1).
An employee shall not be treated as meeting the age and service requirements described in this paragraph until the first date on which, under the plan, any employee with the same age and service would be eligible to commence participation in the plan.
If, under section 414(r), an employer is treated as operating separate lines of business for a year, the employer may apply the requirements of this subsection for such year separately with respect to employees in each separate line of business.
Subparagraph (A) shall not apply with respect to any plan maintained by an employer unless such plan benefits such employees as qualify under a classification set up by the employer and found by the Secretary not to be discriminatory in favor of highly compensated employees.
The term “highly compensated employee” has the meaning given such term by section 414(q).
In the case of contributions which are subject to section 401(k) or 401(m), employees who are eligible to contribute (or elect to have contributions made on their behalf) shall be treated as benefiting under the plan (other than for purposes of paragraph (2)(A)(ii)).
A plan maintained by an employer which has no employees other than highly compensated employees for any year shall be treated as meeting the requirements of this subsection for such year.
The Secretary shall prescribe such regulations as may be necessary or appropriate to carry out the purposes of this subsection.
If the church or convention or association of churches which maintains any church plan makes an election under this subsection (in such form and manner as the Secretary may by regulations prescribe), then the provisions of this title relating to participation, vesting, funding, etc. (as in effect from time to time) shall apply to such church plan as if such provisions did not contain an exclusion for church plans.
An election under this subsection with respect to any church plan shall be binding with respect to such plan, and, once made, shall be irrevocable.
