How does FERS special retirement work for law enforcement and firefighters?

Short answer

Federal law enforcement officers, firefighters, air traffic controllers, Customs and Border Protection officers, nuclear materials couriers, and Capitol and Supreme Court Police can retire at 50 with 20 years of covered service, or at any age with 25. Their annuity is 1.7% of high-3 for each of the first 20 years plus 1% for each year after. Most must leave by 57 (56 for air traffic controllers). In exchange, they pay a half point more of pay into FERS.

Who is covered

The special provisions are written into the FERS law at 5 U.S.C. 8412(d) and (e). They cover service as (5 U.S.C. 8412):

Coverage depends on your position, not just your job title. Your agency decides whether a position is covered, and your personnel records carry a retirement plan code that reflects it. OPM's code tables, for example, list separate codes for law enforcement and firefighter service. If you're not sure, ask HR now, because the difference is worth a lot over a retirement. The law lets service in different covered groups be combined toward the 20 or 25 years, except for air traffic controllers, who count their own service.

When you can retire

GroupUnreduced retirement
LEO, firefighter, CBP, nuclear courier, Capitol or Supreme Court PoliceAge 50 with 20 years, or any age with 25 years
Air traffic controllersAge 50 with 20 years, or any age with 25 years

The years must be in covered positions. If you have a mix of regular and covered service, you can still use the regular FERS routes, such as your MRA with 30 years, but the special formula applies only when you retire under the special provisions. See When can I retire under FERS? for the regular routes, and OPM: Types of retirement.

Mandatory retirement age

Most covered employees must separate at a set age, under 5 U.S.C. 8425 (5 U.S.C. 8425):

GroupMust separate atCan be extended to
LEO, firefighter, CBP, nuclear courier5760, by the agency head
Air traffic controller5661, for exceptional skills
Supreme Court Police5760
Capitol Police57Up to 62, set by the Capitol Police Board

Separation happens on the last day of the month you reach that age, or the month you complete 20 years of covered service if you are already older. Your agency must give you written notice at least 60 days ahead. The extensions are for "the public interest," and they're not automatic.

That second part matters for people who start covered service later in life: someone who is 57 with only 17 covered years isn't forced out until the month they complete 20 years. Ask your agency's HR office how the rules apply to your position and start date.

The annuity formula

OPM's computation page sets out the special formula, which applies when you retire under the special provisions (OPM: FERS computation):

Years of serviceShare of high-3
2034%
2539%
3044%

For comparison, a regular FERS employee with 20 years gets 20% (or 22% at 62 and older). Because years after 20 add only 1% each, the reward for staying longer drops sharply after 20 years, which is one reason many covered employees retire close to 20 or 25 years.

Supplement, earnings test and COLAs

Special provision retirees get three advantages on top of the formula:

The TSP also has a matching rule: public safety employees who separate in or after the year they turn 50 can take TSP payments without the 10% early withdrawal penalty (TSP withdrawal options).

Higher contributions

Covered employees pay 0.5 percentage point more of their pay into FERS than regular employees in the same group (OPM: BAL 13-102 and BAL 14-102):

When first coveredRegularSpecial provision
FERS (generally before 2013)0.8%1.3%
FERS-RAE (2013)3.1%3.6%
FERS-FRAE (2014 and later)4.4%4.9%

Agencies pay much more. For October 2026, OPM set the agency share for law enforcement, firefighters and CBP officers in regular FERS at 37.6% of pay, versus 17.9% for regular employees (OPM: BAL 26-307).

Example

Taylor is a made-up federal law enforcement officer born in 1974 (MRA 57), who retires at 52 with 25 years of covered service and a $110,000 high-3.

  1. First 20 years: $110,000 × 1.7% × 20 = $37,400.
  2. Next 5 years: $110,000 × 1% × 5 = $5,500.
  3. Annual annuity: $42,900, or $3,575 a month, before survivor reduction and taxes.
  4. Supplement: paid from 52 to 62. Taylor can work any job until 57 with no earnings test, then the test applies from 57 to 62.
  5. COLAs: start with the first December after retirement (prorated the first time), not at 62.
  6. Comparison: under the regular formula, 25 years would give $110,000 × 1% × 25 = $27,500. The special formula pays $15,400 more a year.

What to do next

  1. Confirm your coverage. Ask HR to confirm in writing that your position is covered special retirement service.
  2. Count covered years. Know your 20-year and 25-year dates and your mandatory separation date.
  3. Plan your post-retirement work. Look at whether a second career after your MRA would trigger the supplement earnings test.
  4. Get an estimate. Ask your agency for an annuity estimate under the special formula.

Common questions

Can federal law enforcement retire at 50?

Yes, with 20 years of covered service. With 25 years of covered service, they can retire at any age.

What is the mandatory retirement age for federal law enforcement?

57, or when you complete 20 years if you're older than 57 by then. The agency head can extend it to 60 in the public interest. Air traffic controllers must leave at 56.

How is the FERS special provision annuity calculated?

1.7% of high-3 times years of service up to 20, plus 1% of high-3 for each year over 20.

Do special provision retirees get COLAs before 62?

Yes. Their annuities get FERS COLAs at any age.

Is the FERS supplement subject to the earnings test for law enforcement?

Not until you reach your MRA. From the MRA to 62, the normal earnings test applies.

How much more do special provision employees contribute?

Half a percentage point more than regular employees: 1.3%, 3.6% or 4.9% of pay depending on when you were first covered.
