Special Provisions Retirement: LEO, Firefighter & ATC

Updated June 2026 · Educational only — not financial, tax, or legal advice

If you serve in a federal law enforcement, firefighter, or air traffic control position, you're covered by the FERS Special Provisions — and you have one of the most valuable retirement packages in all of federal service. You also have rules that work very differently from a regular FERS employee's, including a mandatory retirement age that forces the decision whether you're ready or not. This guide pulls the whole picture together.

Who is covered

The special provisions (sometimes called "6(c)" coverage) apply to employees in rigorous covered positions, including:

• Law enforcement officers (LEO) — federal officers whose primary duties are the investigation, apprehension, or detention of suspected or convicted criminals
• Firefighters — in rigorous federal firefighting positions
• Air traffic controllers (ATC)
• Customs and Border Protection Officers (CBPO), Capitol Police, Supreme Court Police, nuclear materials couriers, and certain other covered groups

Coverage attaches to the position, which is why which positions count — and keeping that coverage as you move up — matters so much. See covered positions and the secondary-position rules.

When you can retire

Special-provisions employees qualify for an immediate, unreduced annuity at:

• Age 50 with 20 years of covered service, or
• Any age with 25 years of covered service.

That's years — sometimes a decade or more — earlier than a regular FERS employee, who generally waits for their MRA or age 60/62.

The enhanced computation

Your annuity is computed at a richer rate than regular FERS:

Those first 20 years at 1.7% instead of 1.0% are a 70% larger benefit on that block of service. The full mechanics are in how your FERS pension is calculated, and you can run your own number on the FERS calculator (it handles special provisions as a first-class case).

The mandatory retirement age

The trade for early eligibility is that you generally must retire at a set age — 57 for LEOs and firefighters, 56 for air traffic controllers — with limited exceptions. This caps your planning window and makes timing decisions unavoidable. Full detail in mandatory retirement age for LEOs, firefighters & ATCs.

The supplement and your TSP

Two more advantages stack on top:

• The FERS supplement starts immediately at retirement (not at MRA), and is not subject to the earnings test until you reach your MRA — so you can work a full second career and keep it. See the supplement and the earnings test.
• Your TSP is penalty-free earlier — at age 50, or with 25 years of service — instead of the usual age-55 separation rule. See the TSP age-55 rule.

Add it all up and the special provisions are worth far more than the enhanced formula alone — we quantify the whole stack in the special-provisions advantage.

What it costs you

Covered employees pay a slightly higher FERS retirement contribution (an extra 0.5% of pay) toward the enhanced benefit, and accept a rigorous career and a mandatory early exit. For most who qualify, the math is overwhelmingly favorable — but it's worth understanding both sides.
