OPM Retirement Age: FERS, CSRS, and Special Provisions Rules

The OPM retirement age depends on which system covers you and how many years you’ve served. Under the Federal Employees Retirement System (FERS), the earliest you can retire with a full, unreduced annuity is your Minimum Retirement Age (MRA), which falls between 55 and 57 depending on your birth year, and you need 30 years of service at that point. Under the older Civil Service Retirement System (CSRS), the earliest full retirement is age 55 with 30 years. Both systems also allow retirement at 60 with 20 years, or at 62 with just 5 years of service.¹

FERS Minimum Retirement Age by Birth Year

The MRA is the earliest age at which a FERS employee can voluntarily retire and start collecting an annuity. Congress set it on a sliding scale tied to birth year:¹

Born before 1948: age 55
Born in 1948: 55 and 2 months
Born in 1949: 55 and 4 months
Born in 1950: 55 and 6 months
Born in 1951: 55 and 8 months
Born in 1952: 55 and 10 months
Born 1953 through 1964: age 56
Born in 1965: 56 and 2 months
Born in 1966: 56 and 4 months
Born in 1967: 56 and 6 months
Born in 1968: 56 and 8 months
Born in 1969: 56 and 10 months
Born 1970 or later: age 57

For most of today’s federal workforce, the MRA is 57. Your exact MRA matters because it controls when you can start an annuity, when you become eligible for the FERS Special Retirement Supplement, and in some cases whether you can carry federal health insurance into retirement.

FERS Age and Service Combinations for a Full Annuity

An immediate FERS retirement means your annuity starts on the first day of the month after you separate.² Three combinations qualify you for a full, unreduced annuity:¹

Your MRA with 30 years of service
Age 60 with 20 years of service
Age 62 with 5 years of service

These thresholds are firm. Miss the service requirement by even a few months and you either wait for the next threshold or accept a reduced annuity. Creditable service includes most time in a FERS-covered position, plus military service for which a deposit has been paid.

Age at retirement also drives the annuity multiplier. Retire at 62 or later with at least 20 years of service, and OPM computes your annuity at 1.1% of your high-3 average salary per year of service instead of the standard 1%.³ That 0.1% bump is a real reason to consider working past 62 if you’re close to 20 years.

Retiring Early Under MRA+10

If you’ve hit your MRA but have only 10 years of service, you can retire immediately under the MRA+10 provision. The annuity is permanently reduced by 5% for each year you’re under age 62, prorated to 5/12 of 1% per month.⁴ Retiring at 57 when your MRA is 57 leaves you five years short of 62, which locks in a 25% cut for life. The reduction never lifts, even after you reach 62.

At least five of the 10 years must be civilian service. MRA+10 retirees also do not qualify for the FERS Special Retirement Supplement, which tightens the pre-62 budget further.

Postponed and Deferred Retirement

If you leave federal service before qualifying for an immediate annuity, two separate paths lead to eventual benefits.

Postponed Retirement

An MRA+10 employee who doesn’t want the 5% annual reduction can separate and delay the start of the annuity. Wait until age 62, and the reduction disappears entirely. Wait until age 60 with at least 20 years of service, and it also disappears.⁵ When your annuity begins, you can re-enroll in the Federal Employees Health Benefits program (FEHB), Federal Employees’ Group Life Insurance (FEGLI), and federal dental and vision coverage.⁶ Unused sick leave still counts toward the annuity calculation.

Deferred Retirement

If you leave without qualifying for any immediate benefit and you have at least five years of creditable civilian service, you can claim a deferred annuity at age 62 with no age-based reduction.⁷ The trade-off is significant: deferred retirees lose FEHB, FEGLI, and federal dental and vision coverage permanently, and sick leave doesn’t count toward the annuity. For someone who left at 35 with eight years in, the deferred annuity is a real benefit but rarely the foundation of a retirement plan.

CSRS Retirement Ages

CSRS covers employees hired before January 1, 1984, who did not convert to FERS. It uses fixed benchmarks with no sliding scale:⁸

Age 55 with 30 years of service
Age 60 with 20 years of service
Age 62 with 5 years of civilian service

All three produce an unreduced annuity. CSRS employees who don’t meet any of these combinations before separating may still qualify for a deferred annuity at age 62 if they completed at least five years of civilian service.

Special Provisions Retirement Ages

Law enforcement officers, firefighters, nuclear materials couriers, customs and border protection officers, and air traffic controllers work under separate rules. They can retire earlier, but they also face a mandatory separation age the general workforce doesn’t.

Under FERS, these employees qualify for an immediate, unreduced annuity at age 50 with 20 years of covered service, or at any age with 25 years of covered service.¹ The service must be in a qualifying position; time in a non-covered role doesn’t count toward the 20 or 25. The same age-and-service combinations apply under CSRS.⁸

The other side of the special provisions rules is a hard ceiling. Under FERS, law enforcement officers, firefighters, nuclear materials couriers, and customs and border protection officers must separate by age 57, or upon completing 20 years of service if they’ve already passed 57. Air traffic controllers must separate at 56.⁹ Under CSRS the same ages apply, but agency heads can grant limited exemptions: law enforcement officers and firefighters can be exempted until age 60, and air traffic controllers with exceptional skills until age 61.¹⁰

Voluntary Early Retirement Authority

During reorganizations, reductions in force, or workforce restructuring, agencies can ask OPM to approve Voluntary Early Retirement Authority (VERA). When VERA is in effect, employees can retire at age 50 with 20 years of service, or at any age with 25 years of service.¹¹ These are the same thresholds used for discontinued service (involuntary) retirement.¹²

VERA is not a standing benefit. It has to be specifically authorized for a particular agency or component during a defined window. When it is offered, the annuity uses the standard FERS formula with no age-based reduction, which distinguishes it sharply from MRA+10. Employees who retire under VERA at or after their MRA also qualify for the Special Retirement Supplement.

How Retirement Age Affects the Special Retirement Supplement

FERS employees who retire before age 62 with an unreduced annuity receive a temporary payment called the Special Retirement Supplement, designed to approximate the Social Security benefit earned through federal employment.¹³ It’s payable to retirees who leave under one of these paths:¹⁴

MRA with 30 years of service
Age 60 with 20 years of service
Special provisions retirement
Involuntary or early retirement (VERA or discontinued service) at or after the MRA

MRA+10 retirees and deferred retirees do not receive the supplement. The supplement stops at age 62 or when you first become eligible for Social Security, whichever comes first, and it’s subject to an earnings test similar to Social Security’s: in 2026, the supplement is reduced by $1 for every $2 in wages or self-employment income above $24,480.¹⁵ Investment income, TSP withdrawals, and the FERS pension itself don’t count. For special provisions retirees, the earnings test doesn’t apply until they reach their MRA.

Retirement Age and Federal Health Benefits

To carry FEHB coverage into retirement, you must retire on an immediate annuity (one that begins within a month of separation), and you must have been continuously enrolled in FEHB for the five years immediately before retirement.¹⁶ If you had fewer than five years of service, you need to have been enrolled since your first opportunity.

This is where retirement timing does more than shape your annuity. Deferred retirees lose FEHB access entirely because their annuity doesn’t start immediately. Employees who dropped their FEHB enrollment for even a single pay period during the final five years can be disqualified. OPM can grant waivers in limited circumstances, and the request would go through your agency’s human resources office.¹⁷ Postponed MRA+10 retirees do regain FEHB eligibility when their annuity commences, one reason postponement often beats deferral when both are on the table.
