Key Takeaways
- Not all military service automatically counts toward FERS retirement—eligibility and deposits matter.
- Accurate information about veterans’ benefits and FERS is best sourced from official government channels.
Are you a federal employee with a history of military service, or a retiree looking to understand how your service counts toward your FERS retirement? Sorting facts from myths can be challenging. This guide will help you navigate the most frequent misconceptions using current rules and thoroughly sourced explanations.
What Are Military Service Credits?
Definition and eligibility
Military service credit refers to how your time served in the uniformed services can be counted toward your federal retirement benefits. Typically, this includes active-duty service in the Armed Forces, and in some situations, service with the National Guard or Reserve. To qualify, your service must be considered “creditable,” meaning it isn’t already being used for a military retirement based on active-duty service alone (unless you meet specific exceptions explained in OPM guidance).
How credits apply under FERS
The Federal Employees Retirement System (FERS) allows certain periods of prior military service to count toward your years of federal civilian service, increasing your total creditable service for retirement. However, your service time is not credited automatically. Usually, you must make a military service “deposit,” which is a payment to the federal retirement fund that ensures your military service is included in your FERS retirement calculation.
Impact on federal retirement
If eligible and the deposit is made, this credit can boost your total service years, potentially letting you reach vital retirement milestones (like eligibility for an unreduced annuity) sooner. It may also increase your final annuity amount. However, if you already receive a military retirement (based on active-duty service), you generally cannot count that same service toward FERS unless you waive your military retirement pay.
Common Myths About Veterans’ FERS Eligibility
Myth: All service counts automatically
It’s a widespread misunderstanding that all prior military service is recognized automatically for FERS retirement. In reality, most federal employees must actively make a service deposit for that time to count. If you do not, the service is not credited for your annuity, regardless of length or type of service.
Myth: Military retirements always combine
Some believe an active-duty military retirement and a FERS retirement can always be “stacked,” meaning the same period of service boosts both pensions. In fact, federal law is clear: You can only count military service toward both retirements in very limited circumstances, typically involving reserve retirements or by formally waiving your military retired pay for FERS purposes. The vast majority of military retirees must choose one system for each year of service.
Myth: Service credit waives any FERS requirements
It’s sometimes assumed that buying back military service credits means you can ignore other FERS requirements, like the minimum years of federal civilian service or age benchmarks. This is not correct. All standard FERS eligibility rules—such as the “five years of creditable civilian service” minimum—still apply even if you buy back military time.
Fact or Fiction: How is Eligibility Decided?
Service deposit requirements
To count your military service toward a FERS annuity, you must usually make a service deposit. This deposit is calculated based on a percentage of your military base pay and must be paid in full, with interest, by the time you retire. If you do not pay this deposit, your military service will only count for certain purposes, like leave accrual, but not for retirement annuity computation.
Breaks in service and counting time
Breaks between your military and civilian federal careers can affect your eligibility, but they do not automatically disqualify your service from being credited. The relevant timeframes are clearly defined, and as long as your service periods are verified and all deposits are made, breaks do not necessarily bar you from including military time in your total.
Official sources for eligibility determinations
Your eligibility for military service credit under FERS is governed by federal statutes, Office of Personnel Management (OPM) regulations, and agency guidance. These sources provide the definitive rules. If you are uncertain about your eligibility, reference the current OPM guidance and check with your agency’s human resources officials—they rely on these same statutory sources, and any interpretation should align with official policy.
How Does Buying Service Credit Work?
Process for making a service deposit
To buy service credit, you typically submit a request through your agency’s human resources office. They’ll help you verify documents, such as your DD Form 214, and provide instructions for submitting a deposit. Payments are made directly to the appropriate federal agency—not to private organizations or individuals.
Deadlines and documentation
There are firm deadlines for making your service deposit—usually before you retire or leave federal service for good. You’ll need to provide official documents proving your active-duty service and pay records. Late payments may lead to additional interest or even loss of eligibility, so timely action is essential if you want your service counted.
Potential effects on benefits
Making the deposit allows your military service to be included in your civilian service computation for annuity purposes. This could help you reach retirement milestones sooner and may increase your annuity. However, the cost and financial impact should be reviewed using official OPM estimators and documentation, keeping in mind that the rules are standardized, not individualized.
What If You Receive VA Disability?
Interaction with FERS and CSRS
Receiving a VA disability benefit does not disqualify you from making a deposit for military service credit under FERS or CSRS. You can receive both, provided your service is otherwise creditable and you meet the deposit requirements. However, if you draw both military retired pay and a FERS annuity, the usual rules apply: military retired pay generally must be waived, unless you are a reservist.
Survivor and spousal benefits considerations
Service credit can influence survivor annuity eligibility and amounts under FERS or CSRS. When planning for survivors, ensure that all service—including bought-back military time—is fully credited and properly documented, following OPM survivor benefit rules.
Rules after the Windfall Elimination Provision repeal
As of 2025, the Windfall Elimination Provision (WEP) no longer affects federal employees’ Social Security benefits. This change means your military service credit and any Social Security you earn are not subject to offsets under WEP, simplifying coordination of your benefits.
Which Myths Cause the Most Confusion?
Overlapping federal and military service periods
A frequent point of confusion is whether you can double-count periods of overlapping federal civilian and military service. In general, you cannot get retirement credit for the same periods in both systems. Official rules specify what can and cannot be double-counted.
Effect of partial versus full-time military service
Some believe that even brief or part-time military service counts the same as full-time service for FERS purposes. In fact, only qualifying active-duty service counts, and typically only after a deposit is made.
Misunderstandings about dual eligibility
Dual eligibility—in both military and federal retirement plans—has strict limits. The rules, set by federal law and OPM, define which benefits may be combined and when waivers or deposits are required.
Where to Find Official Benefit Answers?
Government agency sources
Information about FERS, CSRS, and military service credits is available directly from OPM (opm.gov), the Defense Finance and Accounting Service (DFAS), the Department of Veterans Affairs (va.gov), and your federal agency’s human resources office. Use these primary, official sources whenever possible.
OPM and federal statutes
OPM administers the federal retirement systems and issues implementing regulations and guidance. Federal statutes passed by Congress are the foundational law; OPM regulations clarify how these statutes work in real retirement scenarios.
Best practices for validating information
To ensure your decisions are grounded in fact, cross-check what you hear or read with primary government publications, agency resources, and the official OPM website. Avoid informal advice from non-official sources when making decisions about your benefits.
