PART 1_INCOME TAXES--Table of Contents
 
Sec. 1.410(a)-5  Year of service; break in service.

    (a) Year of service. For the rules relating to years of service 
under subparagraphs (A), (C), and (D) of section 410(a)(3), see 
regulations prescribed by the Secretary of Labor under 29 CFR Part 2530, 
relating to minimum standards for employee pension benefit plans.
    Rules relating to a general rule for a year of service, hours of 
service, and maritime industries apply for purposes of section 410(a) 
and the regulations thereunder.
    (b) Seasonal industries. For rules which relate to seasonal 
industries under section 410(a)(3)(B), see regulations prescribed by the 
Secretary of Labor under 29 CFR Part 2530, relating to minimum standards 
for employee pension benefits plans.
    (c) Breaks in service--(1) General rule. This paragraph provides 
rules with respect to breaks in service under section

[[Page 538]]

410(a)(5). Except as provided in subparagraphs (2), (3), (4), and (5) of 
this paragraph, all of an employee's years of service with the employer 
or employers maintaining a plan are taken into account in computing his 
period of service under the plan for purposes of section 410(a)(1) and 
Sec. 1.410(a)-3.
    (2) Employees under 3-year 100 percent vesting schedule--( i) 
General rule. In the case of an employee who incurs a 1-year break in 
service under a plan which provides that after not more than 3 years of 
service, each participant's right to his accrued benefit under the plan 
in completely nonforfeitable (within the meaning of section 411 and the 
regulations thereunder) at the time such benefit accrues, the employee's 
service before the break in service is not required to be taken into 
account after the break in service in determining the employee's years 
of service under section 410(a)(1) and Sec. 1.410(a)-3 if such employee 
has not satisfied such service requirement.
    (ii) Example. The rules of this subparagraph are illustrated by the 
following example.

    Example. A qualified plan computing service by the actual counting 
of hours provides full and immediate vesting. The plan can not require 
as a condition of participation that an employee complete 3 consecutive 
years of service with the employer because the requirement as to 
consecutive years is not permitted under section 410(a) (5). However, 
such a plan can require 3 years without a break in service, i.e., 3 
years with no intervening years in which the employee fails to complete 
more than 500 hours of service. Under a plan containing such a 
participation requirement, the following example illustrates when 
employees whould become eligible to participate.

------------------------------------------------------------------------
                                            Hours of service completed
                                        --------------------------------
                  Year                    Employee   Employee   Employee
                                             A          B          C
------------------------------------------------------------------------

2......................................      1,000      1,000        500
3......................................      1,000        700      1,000
4......................................      1,000      1,000        700
5......................................      1,000      1,000      1,000
6......................................      1,000      1,000      1,000
------------------------------------------------------------------------
Note. Employee A will have satisfied the plan's service requirement at
  the end of year 3. Employee B at the end of year 4, and Employee C at
  the end of year 6.


    (3) One-year break in service--(i) In general. In computing the 
period of service of an employee who has incurred a 1-year break in 
service, for purposes of section 410(a)(1) and Sec. 1.410(a)-3, a plan 
may disregard the employee's service before the break until the employee 
completes a year of service after such break in service.
    (ii) Examples. The rules provided by this subparagraph are 
illustrated by the following examples.

    Example (1). Employee A completes a year of service under a plan 
computing service by the actual counting of hours for the 12-month 
period ending December 31, 1980, and incurs a 1-year break in service 
for the 12-month period ending December 31, 1981. The plan does not 
contain the provisions permitted by section 410(a)(5)(B) (relating to 3-
year 100 percent vesting) and section 410(a)(5)(D) (relating to 
nonvested participants). Thereafter, he does not complete a year of 
service. As of January 1, 1982, in computing his period of service under 
the plan his service prior to December 31, 1981, is not required to be 
taken into account for purposes of section 410(a)(1) and Sec. 1.410 
(a)-3.
    Example (2). The employee in example (1) completes a year of service 
for the 12-month period ending December 31, 1982. Prior to December 31, 
1982, in computing the employee's period of service as of any date 
occurring in 1982, the employee's service before December 31, 1981, is 
not required to be taken into account for purposes of section 410(a)(1) 
and Sec. 11.410(a)-3. Because the employee completed a year of service 
for the 12-month period ending December 31, 1982, however, his period of 
service is redetermined as of January 1, 1982. Upon completion of a year 
of service for 1982, the employee's period of service, determined as of 
any date occurring in 1982, includes service prior to December 31, 1981.

    (4) Nonvested participants--(i) General rule. In the case of a 
participant in a plan who does not have any nonforfeitable right under 
the plan to his employer-derived accrued benefit and who incurs a 1-year 
break in service, for purposes of section 410(a)(1) and Sec. 1.410.(a)-
3 the plan may disregard his years of service prior to such break if the 
number of his consecutive 1-year breaks in service equals or exceeds his 
aggregate number of years of service prior to such break. In the case of 
a plan using the elapsed time method described in Department of Labor 
regulations, the plan may disregard such years of service prior to such 
break if the period of severance is at least 1 year and the period of 
severance equals or exceeds the prior period of service,

[[Page 539]]

whether or not consecutive, completed before such period of severance. 
The plan may in computing such aggregate number of years of service 
prior to such break disregard any years of service which could have been 
disregarded under this subparagraph by reason of any prior break in 
service.
    (ii) Examples. The rules of this subparagraph are illustrated by the 
following example:

    Example. In 1980, A, who was hired at age 35, separates from the 
service of X Corporation after completing 4 years of service. At this 
time A had no vested benefits. In 1985, after incurring 5 consecutive 
one-year breaks in service, A was reemployed. Under section 
410(a)(5)(D), A's 4 years of service may be disregarded because they are 
exceeded by the number of years of consecutive one-year breaks (5) after 
such service.

    (d) Special continuity rule for certain plans. For special rules for 
computing years of service in the case of a plan maintained by more than 
one employer, see regulations prescribed by the Secretary of Labor under 
29 CFR Part 2530, relating to minimum standards for employee pension 
benefit plans.
