FERS special provisions let covered law enforcement officers, firefighters and air traffic controllers retire at 50 with 20 years of covered service or at any age with 25. Their pension uses 1.7 percent of high-3 for each of the first 20 years and 1 percent after that, and most face a mandatory retirement age.
These jobs are hard on the body. Chasing suspects, running into burning buildings and keeping aircraft apart for hours at a time are young people's work, and Congress built the special provisions so these careers could end earlier without leaving people short. The deal is generous, but it is a deal: earlier retirement and a richer formula, in exchange for a hard stop.
Think of it as an express lane with a fixed exit. You get there faster, and the ride pays more per mile. But the exit comes at a set age whether you are ready or not, so the planning has to start earlier too. This guide covers who qualifies, how the formula works, the mandatory ages, and what the supplement, COLAs and TSP look like on this track.
01Who is covered by FERS special provisions?
FERS special provisions cover law enforcement officers, firefighters, air traffic controllers, and a few other groups named in law, including Capitol Police, Supreme Court Police and nuclear materials couriers (OPM, retrieved 2026-10-11). Coverage depends on the duties of your position as determined by your agency, not on your job title.
- Law enforcement officer (LEO)A position whose primary duties are investigating, apprehending or detaining people suspected or convicted of federal crimes, or a supervisory position over that work.
- FirefighterA position whose primary duties are controlling and extinguishing fires, or a supervisory position over that work.
- Air traffic controller (ATC)A controller actively separating air traffic, or a first-level supervisor of controllers, under the statutory definition.
- Covered serviceTime in a position your agency has approved for special-provision coverage. Only covered service earns the 1.7 percent rate.
- Primary and secondary positionsPrimary positions are front-line jobs; secondary positions are supervisory or administrative roles you move into after primary service, which can keep coverage.
Because coverage is a determination tied to your service record, two people with the same title can have different coverage. If you believe you are in covered service, confirm it in writing with your agency and check that your SF-50 shows the right retirement code. Errors here are much easier to fix while you are working than after you apply.
02When can special-provision employees retire?
Special-provision employees can retire on an immediate, unreduced annuity at age 50 with 20 years of covered service, or at any age with 25 years of covered service (OPM, retrieved 2026-10-11). That is years earlier than the regular FERS combinations.
| Track | Earliest unreduced retirement | Mandatory retirement |
|---|---|---|
| Law enforcement officer | 50 with 20 years, or any age with 25 | 57, or later to complete 20 years |
| Firefighter | 50 with 20 years, or any age with 25 | 57, or later to complete 20 years |
| Air traffic controller | 50 with 20 years, or any age with 25 | 56, or later to complete 20 years |
| Regular FERS (for comparison) | MRA with 30, 60 with 20, or 62 with 5 | None |
Sources: OPM FERS types of retirement (retrieved 2026-10-11); Congressional Research Service report R42631 for mandatory ages (retrieved 2026-10-11).
Someone hired into a covered position at 25 could, under these rules, retire at 50 with 25 years. Someone hired at 37 reaches 20 years at 57, right at the law enforcement and firefighter mandatory age. That is why the maximum entry age for many covered positions is set where it is.
03How is the special-provision annuity calculated?
A FERS special-provision annuity is 1.7 percent of your high-3 for each of the first 20 years of covered service, plus 1 percent for each year of service beyond 20 (OPM, retrieved 2026-10-11). Twenty years at 1.7 percent equals 34 percent of high-3, compared with 20 percent under the regular formula.
The high-3 works the same way it does for everyone else: your highest average basic pay over any three consecutive years, including locality pay. For law enforcement officers, law enforcement availability pay (LEAP) is generally part of basic pay for retirement purposes, which can raise the high-3; confirm how your agency codes it. Overtime outside those rules generally does not count. The FERS annuity guide explains the high-3 in detail.
04What is a worked example?
Here is a law enforcement career figured with the special-provision formula.
In this example the special provisions add $15,400 a year compared with the regular formula on the same high-3 and service. On top of that, this retiree would receive the FERS supplement from 52 until 62. To run your own numbers, use the FERS pension estimator and select the special-provision formula.
The special provisions do not just start the pension sooner. They make each of the first 20 years worth 70 percent more than a regular year.

05What is the mandatory retirement age?
Most special-provision employees face a mandatory retirement age: 57 for law enforcement officers and firefighters, and 56 for air traffic controllers, or later if needed to complete 20 years of service (CRS, retrieved 2026-10-11). Agency heads can grant limited exemptions in some cases.
This is the fixed exit on the express lane. A mandatory age changes planning in three ways.
- Your last day may not be your choice. Plan income for the years after the mandatory age, which usually come years before 62.
- The years from 57 to 62 matter. The supplement covers part of the gap; the TSP and any second career often cover the rest.
- Late entrants need a count. If you entered covered service later in life, check exactly when you reach 20 years.
If you leave covered service before you qualify, your covered years still count as service, but you may end up on the regular FERS formula and eligibility rules. The eligibility guide covers those combinations.
06How do the supplement and COLAs work for special provisions?
Special-provision retirees receive the FERS supplement from retirement until 62, and they receive cost-of-living adjustments before 62, which regular FERS retirees do not (OPM, retrieved 2026-07-05). Both make the early years more workable.
The supplement approximates the Social Security you earned during federal service. For a special-provision retiree, it can run for many years: from 50 to 62 is twelve years. The earnings test, which reduces the supplement $1 for every $2 earned above an annual limit, does not apply to earnings before you reach your Minimum Retirement Age (OPM RI 92-22, retrieved 2026-10-11). Once you pass your MRA, it does. If you plan a second career, that MRA date is worth knowing. The supplement guide explains the test.
Special-provision COLAs follow the FERS diet-COLA rule: when inflation runs between 2 and 3 percent, the FERS COLA is capped at 2 percent, and above 3 percent it is the full figure minus one point. The January 2026 FERS COLA was 2.0 percent (OPM, retrieved 2026-07-05).
07How does the TSP work for special-provision retirees?
Special-provision retirees can take TSP withdrawals without the IRS early withdrawal penalty if they separate in or after the year they turn 50, or at any age with 25 years of covered service (TSP, retrieved 2026-07-05). Regular employees generally need to separate in or after the year they turn 55.
- Penalty-free age. Separation in or after the year you turn 50, or 25 years of covered service, avoids the early withdrawal penalty on TSP money.
- Do not roll it out too fast. That exception generally applies to money withdrawn from the TSP itself. Moving it to an IRA first can change the rules.
- Income tax still applies. The penalty exception does not remove ordinary income tax on traditional balances.
- Plan the drawdown. With retirement possible at 50, the TSP may need to last 40 years or more.
The TSP withdrawals guide walks through the options.
08What should you check before you retire on special provisions?
Before you retire on special provisions, confirm your covered service in writing, check every SF-50 for the right retirement code, and make sure any break in covered service is accounted for. A coverage gap can push you onto the regular formula for those years.
- 01
Request a coverage determination
Ask your agency HR office to confirm which periods are covered service.
- 02
Audit your SF-50s
Look for the special-provision retirement code on each covered period.
- 03
Count your covered years
Know exactly when you reach 20 and 25 years.
- 04
Find your mandatory date
Mark the age you must leave and whether you will have 20 years by then.
- 05
Estimate the supplement
Pull your Social Security statement and estimate the bridge to 62.
- 06
Plan for the MRA
Note when the supplement earnings test starts to apply.
- 07
Pay any military deposit
Military time can count toward the regular-rate service once the deposit is paid before you retire.

Military time does not count as covered service for the 1.7 percent rate, but a paid deposit can add it to the 1 percent portion and to eligibility in some cases. Agency HR can confirm how it applies to you.
09Moving forward on the express lane
The special provisions give you an earlier exit and a richer formula, and they ask more of your planning in return. The mandatory age, the long supplement years, the TSP drawdown and the coverage paperwork all need attention earlier than they would on the regular track.

10Questions federal employees ask
What is the retirement age for air traffic controllers?
Under FERS, a covered air traffic controller can retire at 50 with 20 years of covered service or at any age with 25 years. Controllers face a mandatory retirement age of 56, or later if needed to reach 20 years (CRS, retrieved 2026-10-11).
How is a federal law enforcement pension calculated?
A FERS special-provision pension is 1.7 percent of high-3 for each of the first 20 years of service plus 1 percent for each year after 20 (OPM, retrieved 2026-10-11). With a $110,000 high-3 and 25 years, that is $42,900 a year, as an educational estimate.
What is 6(c) retirement?
6(c) is shorthand for the law enforcement and firefighter retirement provisions, named after the section of the CSRS statute that first created them. Under FERS the same coverage is sometimes called 6(c) coverage by habit, though the FERS provisions are in a different section of law.
Do special-provision retirees get a COLA before 62?
Yes. Special-provision retirees are an exception to the rule that FERS retirees receive no cost-of-living adjustment before 62 (OPM, retrieved 2026-07-05). Their COLAs follow the FERS diet-COLA rule.
Do special-provision retirees get the FERS supplement?
Yes. Special-provision retirees receive the FERS supplement until 62, and the earnings test does not apply to earnings before they reach their Minimum Retirement Age (OPM, retrieved 2026-10-11).
What is the mandatory retirement age for federal law enforcement?
Federal law enforcement officers and firefighters generally must retire at 57, or as soon as they complete 20 years of service if that comes later (CRS, retrieved 2026-10-11). Agency heads can grant limited exemptions.
