One of the most underutilized advantages available to separating Service Members is the ability to count military service time toward federal civilian retirement under the Federal Employees Retirement System (FERS).
This benefit does not activate automatically. It requires deliberate action — and in some cases a payment — within specific windows that close if missed.
This article is an educational overview of how military service credit works in the federal civilian employment system, what the documented process generally looks like, and where to go for current, accurate guidance. It is not financial advice, not legal advice, and not a guarantee of eligibility or outcome. See the full disclaimer at the bottom of this page.
When a federal civilian employee who previously served in the U.S. military applies for retirement, the Office of Personnel Management (OPM) and their employing agency calculate retirement benefits based in part on years of creditable service. Under documented federal law and OPM policy, active duty military service may count as creditable service toward FERS retirement — but only under specific conditions and only if the Service Member takes the required steps to make it count.
The program is governed by OPM regulations and the specific rules of the employing federal agency. The general term for this process is a "military service credit deposit" — a payment made to the federal retirement fund to buy back the military service time so it counts toward the FERS retirement calculation.

This is commonly referred to in federal employment circles as a "military buyback."
OPM's published guidance describes this benefit as generally available to federal civilian employees who:
Veterans who are receiving military retired pay face a separate and important consideration — the interaction between military retirement and FERS credit is governed by additional rules that depend on the nature of the retired pay. Veterans in this situation should review current OPM guidance carefully and consult their human resources office before making any decisions.
Meeting the general criteria above does not guarantee eligibility. Eligibility determinations are made by the employing federal agency and OPM based on individual service records and circumstances.
Deposit percentages, interest rates, grace periods, and program rules are subject to change. Always verify current figures directly with your federal agency HR office and OPM.gov.
There is no universal statutory deadline that permanently closes the military buyback window for all federal employees. However, there are two practical deadlines that make early action critical:
OPM's documented policy establishes that interest begins accruing on the unpaid deposit after an initial grace period. That interest compounds over time. A Service Member who enters federal employment, waits five years, and then decides to make the deposit will owe significantly more than one who initiates the process in the first year of federal employment.
Once a federal employee submits retirement paperwork, the window to complete the military service credit deposit may close. Attempting to initiate or complete the deposit after retirement paperwork has been submitted is often not possible. This means that a federal employee who intended to complete the buyback but never did — and then retires — may permanently lose the benefit of counting that military service time.
The practical guidance published by OPM and most federal HR offices is consistent: initiate the military service credit deposit process as early as possible after beginning federal civilian employment.

Military service credit deposit rules, interest rates, applicable percentages, and program eligibility criteria are subject to change based on federal legislation, OPM regulatory updates, and congressional action. Always verify current requirements and figures directly with your federal agency HR office and OPM.gov before initiating or completing the deposit process.
Valor Path Corporation is a 501(c)(3) nonprofit organization on a mission to eliminate Veteran suicide by ensuring every transitioning Service Member has access to knowledgeable, structured support during one of the most vulnerable periods of their lives.
We are currently developing the Veteran Success Partner (VSP) Certification — the first nationally focused, non-clinical professional credential designed specifically for professionals who support Veterans through military-to-civilian transition. The VSP Certification is being built in collaboration with Dallas College and Workcred, a credentialing affiliate of the American National Standards Institute (ANSI), to ensure it meets rigorous professional standards.
The Transition Intel articles on this page reflect the kind of knowledge a trained Veteran Success Partner will carry — accurate, procedural, and grounded in the real decisions transitioning Service Members face.
