LEAVING FEDERAL SERVICE
BEFORE RETIREMENT AGE

Quick answer: if you leave federal service before qualifying for an immediate annuity, you may still receive a FERS pension later — a deferred retirement — if you have at least 5 years of creditable civilian service and you leave your retirement contributions in the fund. The deferred annuity generally can begin at age 62 with 5+ years, or at your minimum retirement age (MRA) with 10+ years (with a possible age reduction). Your high-3 average salary is frozen as of separation, unused sick leave is generally not credited, and FEHB/FEGLI coverage generally does not continue into a deferred annuity.

These are general program rules, not a determination for any individual. Which category you fall into depends on your age, service, and MRA at separation — your agency and OPM confirm it from your official records.

• Your service total: confirm creditable civilian service, and whether any military deposit should be completed before separation — deposits generally cannot be made after you leave.
• Your MRA: OPM sets it between 55 and 57 by birth year; it controls the earliest MRA+10-style start point.
• Contribution refunds: withdrawing FERS contributions generally forfeits the deferred annuity for that service.
• Insurance consequences: FEHB and FEGLI generally do not continue into a deferred annuity — a significant, individual consideration to review with your benefits office.
• The age reduction: an MRA+10-style deferred annuity is generally reduced 5% for each year you are under 62 when it begins, unless you delay the start.

There is no separate “DoD retirement system” for civilians: Department of Defense civilian employees, USPS employees, and most other executive-branch employees all retire under the same government-wide FERS or CSRS statutes OPM administers, so the deferred-retirement framework on this page applies the same way. The exceptions are special provisions — law enforcement officers, firefighters, air traffic controllers, and dual-status National Guard/reserve military technicians, who have their own statutory rules (including special treatment for certain technicians involuntarily separated due to loss of military membership). Those cases cannot be safely generalized on a website: if one may apply to you, your servicing HR office and OPM are the responsible sources, and a qualified, licensed professional can help you organize the questions.
