Boomerang Employees: Rehires and Retirement Plans
February 2014 Benefit Insights® Newsletter
A boomerang employee (as we will use that name in this article) is, quite simply, one who leaves and then comes
back to work…a rehire. As is so often the case, the retirement plan rules related to rehires are quite different
than those that apply to other areas of employment and benefits. Whether rehiring a former employee is a rare
occurrence or part of your regular course of business, it is important to understand how these rules work.
First Things First
The first step in this analysis is to determine whether the worker is truly a rehire. You may be thinking that it
is pretty obvious, but there can be some ambiguity about whether there was a termination in the first place. If
there wasn't, there can be no rehire. Let's consider several scenarios.
Leave of Absence
There are many reasons an employee may take a leave of absence, and there are several other laws, including the
Family and Medical Leave Act and the Uniformed Services Employment and Reemployment Rights Act, that may confer
special employment rights on those who are covered. As a result and depending on the specifics, a leave of absence
may not be a termination of employment; therefore, when the employee returns to work, he or she is not truly a rehire.
Inconsistent Work Schedule
Some employees may have inconsistent work schedules, working more hours one month and very few or no hours in
another. This may be more prevalent in industries such as retail sales or hospitality. There are several other
fairly common arrangements that fall into this category:
- “Per Diem” Employees: work a day here and there on an as-needed basis (often in healthcare-related fields);
- Interns: consistently work during each school break but do not work at all while school is in session;
- Seasonal Employees: return to work at the same general time each year, e.g. grounds keepers at a golf course,
but do not work in the off-season.
Are these employees terminated during each gap in their work schedule or are they continuously employed but not on
the schedule? Again, answering that question is a critical first step in determining whether the rehire rules apply.
Another variation is when an employee transfers from one division, location or subsidiary to another. When the
transfer is within the same “employer,” it is not a termination and a rehire, it is continuous employment…even
if the divisions or locations have separate payrolls or financial reporting structures. The same is true for
transfers of employment classification such as a union employee who discontinues his or her union membership
and is reclassified as a non-union employee.
You may be wondering why there are quotes around the word employer. The reason is that there are complex rules
that require multiple companies with certain overlap in ownership or business operations to be treated as a
single employer for retirement plan purposes. An employee who transfers from one such company to another within
the same group is again treated as continuously employed.
Rules of the Road
Once the above determination has been made, there are two general rules we must review. They are known as the
rule of parity and the one-year holdout rule.
Rule of Parity
The rule of parity establishes the requirements that allow an employee's pre-termination service to be permanently
disregarded upon rehire. In short, the employee in question must have been:
- A participant in the plan prior to termination;
- 0% vested at the time of termination; and
- Terminated long enough to incur five consecutive breaks in service.
All three requirements must be met. The first is straightforward; however, keep in mind that someone is a
participant if they are eligible for the plan even if they have not chosen to contribute.
The vesting requirement is a bit trickier and depends on the employee's actual account. Since salary deferrals
must be fully vested at all times, any employee who has made 401(k) deferrals does not meet the vesting
requirement. In other words, there are no circumstances that would allow the company to ignore pre-termination
service regardless of how much time has passed between termination and rehire.
If the employee has never deferred or the plan doesn't allow deferrals, we turn our attention to company
contributions. It is obvious whether a person has vesting credit if a contribution has been made, but what
about an employee who is vested but has no account balance? For example, how would we treat an employee who
has worked for the company for two years and is 20% vested but the company has not made any contributions
during that time frame? The employee is 20% vested in an account with nothing in it.
The rules are somewhat open to interpretation on this point but seem to suggest that such an employee would be
treated as 0% vested in applying the rule of parity. Others argue that such an interpretation seems contrary to
the intent of the law. Should this situation arise, it is a good idea to seek assistance from an experienced
consultant and to make sure that whatever interpretation is adopted is applied consistently.
Breaks in Service
That brings us to five breaks in service. As a general rule, a break in service is a plan year during which an
employee works fewer than 501 hours of service. A couple of quick examples may help here.
Arthur terminates employment on January 31, 2014, having worked 100 hours year to date. Assuming he isn't rehired
before then, he would experience his first break in service at the end of 2014 and his fifth at the end of 2018.
Penelope terminates employment on May 31, 2014, having worked 800 hours year to date. Since she completed at
least 501 hours of service prior to termination, she does not have a break in service for 2014. That means her
first break is in 2015 and her fifth is in 2019.
For plans that use the elapsed time method of counting service, the fifth break in service occurs when the employee
has been terminated for 60 consecutive months.
One-Year Holdout Rule
This rule is much simpler in many ways and allows a company to temporarily ignore a rehire's pre-termination
service. Under the one-year holdout rule, once an employee incurs a single break in service, pre-termination
service is ignored until he or she completes one year of service following rehire. Then all pre-break service
is immediately reinstated retroactive to the date of rehire. A break in service is measured the same way as
described above for the rule of parity, and a year of service generally means a 12-month period in which the
employee works at least 1,000 hours.
Putting the Rules into Play
The above analysis is the hard part. If you've made it this far, putting those results into play is much easier.
There are two main reasons that we care about all of these rules: to determine eligibility and vesting. Let's
take a look at how the results apply to both of these important determinations.
An employee who didn't meet the plan eligibility requirements before terminating is the most straightforward—he
or she must complete those requirements irrespective of breaks in service, etc. Someone who was a participant
prior to termination rejoins the plan immediately on rehire unless either the rule of parity or one-year holdout
A participant who satisfies all three requirements under the rule of parity is treated as a new hire as of the
reemployment date and must satisfy the plan's eligibility requirements that are currently in place in the same
manner as any other new employee. Keep in mind that it is somewhat unusual in a 401(k) plan for an individual
to meet all of the rule of parity requirements, so proceed with caution and double-check your findings if it
looks like a former participant will be treated as a new hire.
The one-year holdout rule can present some unique challenges since it provides retroactive credit for pre-termination
service. Another example will help to illustrate.
Harold is a former participant who is rehired for 20 hours per week on December 1, 2013. Under the one-year holdout
rule, he completes one year of service after his rehire on November 30, 2014, and his pre-termination service is
reinstated retroactively to his rehire date, making him eligible for the plan in 2013.
If the company made a contribution for 2013, Harold is eligible to share in it even though the company could not
have known it at the time they made the deposit. The company is obligated to make a 2013 contribution for Harold,
but they would have to deduct it on their 2014 tax return.
Keep in mind, however, that other plan rules continue to apply. So, if the plan has a separate provision requiring
a participant to work at least 1,000 hours in a plan year to share in a contribution, Harold would not receive a
2013 contribution since he would have only completed 80 hours of service from the December 1st reentry date through
the end of the year.
Another quirk of the one-year holdout rule is whether and how it can be applied to a 401(k) plan. A 401(k) plan,
by its nature, requires a participant to make a deferral election before the pay becomes available. By the time a
participant retroactively reenters the plan under the one-year holdout rule, he or she has already been paid for a
year making it impossible to defer. That could be interpreted as a violation of the terms of the plan. As a result,
it is unusual for 401(k) plans to apply the one-year holdout rule.
Both the rule of parity and the one-year holdout rule are applied in a similar manner for vesting. There is, however,
one very important difference related to the one-year holdout rule: the computation period for determining one year
of service can be different for eligibility than for vesting. Specifically, it is counted from rehire date for
eligibility, but the vesting computation period in many plans is always the plan year. So, using the above example,
although Harold is rehired on December 1, 2013, he will not complete 1,000 hours by the end of the plan year
(December 31, 2013) and would reset the clock on January 1, 2014. That means he would not be given retroactive
credit for vesting until December 31, 2014, one month later than when his service was recognized for eligibility.
Dealing with boomerang employees can be challenging on many fronts. Establishing a procedure to review employment
history will help meet those challenges with regard to the retirement plan. Both the rule of parity and one-year
holdout rule are optional provisions, so it is critical to check your plan document. When questions arise, a call
to an experienced TPA or consultant at the beginning will go a long way to preventing even more daunting challenges
down the road.
