Key Takeaways
- FERS and military retirement systems have unique eligibility and benefit structures for federal and military employees.
- Understanding service credit, payout rules, and recent policy updates is key to making informed retirement decisions.
If you’re approaching retirement as a federal employee or military servicemember, your benefit options and eligibility requirements are uniquely shaped by your role. Let’s walk through how special category employees and military personnel can better compare the Federal Employees Retirement System (FERS) with military retirement, so you can plan more confidently for the road ahead.

Retirement System Eligibility
If you’re classified as an SCE, you are generally covered by the FERS retirement system, but with tailored benefits and earlier eligibility windows. Your role must meet strict criteria—defined by federal law and agency policies—to access these unique retirement provisions. Verification involves agency certification that your duties align with the statutory definitions for special categories. Keep in mind, SCE eligibility is about the position, not just the agency or department.
What Is Military Retirement?
Overview of Military Pension Systems
Military retirement refers to the defined benefit pension programs established for servicemembers in the Army, Navy, Air Force, Marine Corps, Space Force, and Coast Guard. The current system, called the Blended Retirement System (BRS), combines a pension (based on years of service) with defined contributions to the Thrift Savings Plan (TSP). Some retired members are still covered under legacy systems, but new entrants fall under BRS.
Eligibility Criteria Explained
To earn a military retirement pension, you typically must serve at least 20 years on active duty or meet equivalent reserve component requirements (known as “qualifying years” for Guard and Reserve). Factors like discharge status, years of creditable service, and type of duty all influence your eligibility. Early separation or discharge for medical reasons may also enable certain limited benefits, depending on the circumstances.
How Does FERS Work for Special Employees?
Key Features for Special Categories
For special category employees, FERS offers several enhanced features. You accrue retirement benefits at a higher percentage rate per year of service than most other federal employees. FERS also provides these employees with immediate annuity eligibility at an earlier age, recognizing the demanding nature of their roles.
In addition to the basic annuity, SCEs may be eligible for a FERS supplement, designed to bridge income from retirement until Social Security eligibility, and have unique options when it comes to unused sick leave credit.
Retirement Age and Service Requirements
Special category employees become eligible for full, unreduced FERS retirement benefits typically at age 50 with 20 years of qualifying service, or at any age with 25 years of service. These thresholds are notably sooner than the standard FERS minimum retirement age (MRA), which ranges from 55 to 57 for most federal staff depending on birth year and does not offer the same accrual rate.
What Are the Differences Between FERS and Military Retirement?
Service Credit Calculations
Service credit—how your work years are counted—differs significantly between the two systems. In FERS, all years of eligible service, including certain types of military time bought back with a deposit, count toward your retirement calculation. Special category status can further enhance credit accrual. Military retirement calculates service based on years of active duty (or qualifying reserve time), with no opportunity to “buy back” time—that time must be served in uniform.
Benefit Payout Structures
Both FERS and military retirement deliver a monthly annuity, but payout formulas vary. FERS benefits for SCEs use a higher accrual rate per year, leading to a larger pension relative to standard federal positions. The military pension, under BRS, is based on a percentage of your average basic pay over your highest-earning 36 months, with the option to draw from the TSP as a supplemental resource.
One important distinction: FERS includes certain survivor and disability benefits tailored for SCEs, while military retirement offers its own programs, including the Survivor Benefit Plan (SBP) and Combat-Related Special Compensation (CRSC), depending on your status and choices at separation.
Can You Combine FERS and Military Service?
Crediting Military Service Under FERS
If you transitioned from military service to federal civilian employment, you may have the option to “buy back” your active-duty military time, making it count toward your FERS service credit. This process involves paying a deposit based on your military earnings. Successfully completing this buyback adds those years to your FERS calculation, which can increase your pension—but you cannot typically receive both a full military pension and full FERS credit for the same years.
Impact on Federal and Military Benefits
Combining service can have tradeoffs. Electing to buy back military time for FERS may require you to waive your military pension for those years, which is a significant decision. Conversely, some Guard and Reserve retirees may be able to earn a FERS annuity and a military pension if their reserve time doesn’t overlap with their credited FERS service. It’s essential to consider how this decision impacts both immediate retirement income and long-term survivor and healthcare benefits.
Which Retirement System Matches Your Career Path?
Factors to Consider
Choosing between FERS and military retirement depends on your service record, eligibility category, and career goals. Key factors include your total creditable years, whether your service is continuous or split between military and federal civilian roles, and which benefit structure supports your long-term financial goals. Assess the survivor, disability, and health benefits offered by both systems as part of your decision-making process.
Long-Term Planning Considerations
For many, the optimal retirement solution involves coordinating benefits to create a holistic plan. Examine the implications of combining service credits, spousal benefits, and opportunities for continued health insurance coverage under federal programs. Ensure your decision aligns with your personal timeline for retirement, current financial needs, and plans for family support.
How Have Recent Policy Updates Affected Retirement Choices?
Windfall Elimination Provision Changes
In 2025, the Windfall Elimination Provision (WEP)—previously affecting how Social Security benefits were calculated for federal retirees—was repealed. This means that, starting in 2026, your Social Security benefits as a FERS participant are no longer subject to WEP reductions. This policy change can make Social Security a larger component of your overall retirement plan if you’re eligible.
Current Federal Guidance for 2026
As of 2026, federal guidance emphasizes flexibility in retirement planning for SCEs and military personnel. Regulations continue to support buyback opportunities for eligible military service and confirm the continued advantages of earlier retirement ages for special groups. The Office of Personnel Management (OPM) regularly updates retirement guidance, so staying informed ensures you make use of the programs that best match your circumstances.
What Questions Do Employees Frequently Ask?
Eligibility for Dual Benefits
Many federal employees with military backgrounds ask whether they can receive both a military pension and a FERS annuity. The answer depends on how your service credit periods overlap. If your credited military service is used toward your FERS retirements (via buyback), you might need to waive the military pension for those years. Otherwise, separate non-overlapping service may allow both benefits.
Healthcare Coverage Options
Another frequent question is about healthcare in retirement. Retired federal employees under FERS can continue Federal Employees Health Benefits (FEHB) if they meet length-of-service and enrollment criteria. Military retirees have access to TRICARE. If you qualify for both—perhaps via service in both the military and federal civilian sectors—you may be eligible for both types of coverage, allowing you some flexibility in your healthcare choices after leaving government service.
