Retirement Plan Vesting and Forfeitures

Vesting measures ownership. Employee deferrals are always fully vested, while employer contributions may vest under the plan’s schedule unless a rule requires immediate vesting.

What is always vested

An employee’s elective deferrals and related earnings are 100% vested. Safe-harbor required contributions, SIMPLE contributions, and certain other sources also have immediate-vesting requirements.

Common maximum schedules for employer contributions

Years of vesting service Three-year cliff Six-year graded
1 0% 0%
2 0% 20%
3 100% 40%
4 100% 60%
5 100% 80%
6 100% 100%

Service-credit questions

  • Does the plan use hours, elapsed time, or another permitted method?
  • Which computation period applies?
  • Does predecessor or related-employer service count?
  • How do breaks in service and rehire restoration rules operate?
  • Has normal retirement age, death, disability, or plan termination triggered full vesting?

Forfeiture administration

A forfeiture is not free employer money. The plan document must govern when forfeitures occur and how they are used—for example, to pay plan expenses, reduce employer contributions, or provide allocations. The sponsor should use forfeitures timely, reconcile the suspense account, and restore amounts when a rehired participant satisfies the plan’s restoration rules.

Practitioner rule: Calculate vesting from verified service history and the contribution source. Never apply one percentage to the entire account without checking which money source it belongs to.
