Retirement plan changes for long-term, part-time employees

The Internal Revenue Code (the Code) has historically allowed employers to exclude employees who never worked at least 1,000 hours in a 12-month period from an employer sponsored retirement plan. Because of this, part-time employees who never reach this threshold often miss out on an opportunity to set aside money for retirement. Such employees include individuals who have limited time to devote to work, such as parents, caregivers, and students. Additionally, some people have multiple part-time jobs, due to a need for flexibility. Based on data from the Bureau of Labor Statistics, there were close to 25.5 million people working part-time in 2021.

Congress has long been concerned about increasing retirement savings for individuals and included changes to the Code to benefit long-term, part-time (LTPT) employees with the Setting Every Community Up for Retirement Enhancement Act (SECURE 1.0). In short, effective in 2024, SECURE 1.0 requires that 401(k) plans allow employees with more than 500 hours of service in three consecutive 12-month periods to contribute elective deferrals to the plan.

The SECURE 2.0 Act of 2022 (SECURE 2.0), brought forth enhancements to Secure 1.0’s LTPT provisions, effective for plan years beginning after Dec. 31, 2024, which furthers the goal for more individuals to have retirement savings. The 401(k) plan requirement to allow employees to contribute elective deferrals was expanded to 403(b) plans and the period of service was reduced from three to two consecutive 12-month periods. SECURE 2.0 also added clarity to changes made by SECURE 1.0.

401(k) plan sponsors may believe the SECURE 2.0 provisions override SECURE 1.0 and that they do not need to act until 2025. This is not the case. Employers, plan sponsors, and third-party administrators need to understand how plan operations will be affected for plan years beginning in 2024 and what they must do now to be prepared for the changes. They also should be cognizant that the IRS will likely issue additional guidance on these provisions.

Summarized below is a discussion of how the SECURE 1.0 and 2.0 LTPT provisions apply to retirement plan operations. It should be noted that collectively bargained employees and non-resident aliens with no U.S. source income are excluded from the LTPT provisions.

401(k) plans

Plan eligibility

For plan years beginning in 2024, if an employee has three consecutive 12-month periods with more than 500 hours of service in each, the employee must be eligible to enter the plan. Periods beginning prior to Jan. 1, 2021, are not considered when determining eligibility; therefore, 2024 is the first possible year LTPT employees must be allowed to participate in a 401(k) plan for purposes of elective deferrals. An employee’s initial 12-month period ends on their first anniversary date of employment. Subsequent periods can continue to be based on anniversary year or can switch to the plan year. The LTPT employee rules apply to employees who are at least age 21.

For plan years beginning in 2025, the employee needs only two consecutive 12-month periods with more than 500 hours of

Top heavy rules

Plans that are top heavy must satisfy minimum contribution and vesting requirements. An employer can elect to exclude the LTPT employees from these requirements.

A defined contribution plan is a top-heavy plan if the aggregate of the accounts of key employees exceeds 60 percent of the aggregate of the accounts of all employees under the plan.

In determining whether the plan is top heavy, it will not be considered top heavy merely because employer contributions are not made to LTPT employees.

403(b) Plans subject to ERISA

Plan eligibility

The first year a 403(b) plan must allow an LTPT employee to enter the plan is 2025. For plan years beginning in 2025, an employee must have two consecutive 12-month periods with more than 500 hours of service in each. Periods beginning before January 1, 2023, will not be taken into account when determining if the employee has satisfied the two consecutive 12 month periods requirement. Consistent with 401(k) plans, the employee must be at least age 21.

403(b) plans are subject to the universal availability rules and there are employee exclusions unique to the plans. For example, students enrolled in and working at a school can be excluded from participating in the school’s 403(b) plan. The LTPT provisions will likely result in some students being eligible for the plan. However, we expect additional guidance to be released on how these LTPT requirements will interact with the universal availability rules.

401(k) Plans and 403(b) Plans subject to ERISA

Employer contributions

Employers are not required to, but can, make match or nonelective contributions to the accounts of LTPT employees. This includes contributions under the safe harbor 401(k) plan provisions.

Nondiscrimination testing

An employer can elect to exclude LTPT employees from nondiscrimination testing related to elective deferrals (ADP), employer match (ACP) and nonelective contributions (section 401(a)(4)). Additionally, they can be excluded from coverage testing under section 410(b).

Vesting service

A LTPT employee is credited with a year of vesting service for each 12-month period the employee has at least 500 hours of service. For 401(k) plans, 12-month periods beginning prior to Jan. 1, 2021, are not counted. For 403(b) plans, periods beginning prior to Jan. 1, 2023, are not counted. If an employer chooses to make a non-safe harbor employer contribution for LTPT employees, the plan’s normal vesting schedule will apply.

Other operational considerations

There are many factors that come into play for proper administration of the LTPT provisions, including appropriate tracking of hire dates and hours worked in the employer’s HRIS or payroll system, transmission of the information to the plan’s third-party administrator and recordkeeper, and timely notification to LTPT employees of their eligibility for the plan. 401(k) plan sponsors should have already laid out a strategy for how to handle tracking of the appropriate data since periods beginning in 2021 count towards eligibility. Sponsors of 403(b) plans will now need to do the same.

Employers should evaluate their systems and the additional administrative burden involved with operating their plans under the LTPT provisions. Furthermore, sponsors should review their plan design and consider whether allowing all employees to enter the plan for purposes of deferral contributions immediately upon hire would be worthwhile. All employees could be treated the same, avoiding the need to carve out employees for different purposes.

Service requirements can continue to be applied for purposes of employer contributions. However, employers should consider whether they want LTPT employees to share in employer contributions and, if so, how to track hours for vesting purposes.

Conclusion

The LTPT provisions are only the tip of the iceberg when it comes to retirement plan changes brought about by SECURE 2.0. This is the perfect time for a holistic review of an employer’s retirement plan design and operations against the required changes and discretionary provisions of SECURE 2.0. In any such review, the employer should work closely with their retirement plan advisors as they need to consider if and how recordkeepers and third party administrators can accommodate their desires.
