I’ve sat across from more than a few federal employees who assumed — reasonably — that buying back their military time would somehow reduce their VA disability rating. It doesn’t. And it can’t, because the two programs operate in different lanes and don’t talk to each other the way people sometimes fear they do.
But the assumption isn’t crazy. It comes from the way the federal system handles military retired pay, which doesinteract with VA disability through a separate rule called the VA–DoD offset. A military buyback is a different transaction. The buyback is about crediting your active-duty service toward a federal civilian FERS annuity. VA disability is a separate compensation program for service-connected conditions. The two never offset each other.
The two systems, kept separate.
VA disability compensation is administered by the Department of Veterans Affairs under 38 U.S.C. Chapter 11. The rating is based on service-connected medical conditions, and it is paid to the veteran regardless of whether they are working, retired, or drawing another federal benefit. There is no provision in Title 38 that reduces or offsets a VA disability award because the veteran made a deposit to credit the same period of service toward a civilian retirement.
The military buyback, by contrast, is administered by OPM under 5 U.S.C. § 8334(j) and the corresponding CSRS provision. It is about federal civilian retirement credit, not veteran status, not medical condition, not service-connected disability. OPM does not query VA records to determine a buyback deposit, and the buyback election does not show up on a VA file.
Where the actual interaction lives.
The thing federal employees get confused by is the rule thatdoes affect both pockets: the offset against military retired paywhen a veteran receives VA disability. Under 38 U.S.C. § 5304, a veteran who qualifies for both military retired pay and VA disability for the same period of service must waive the retired pay in order to receive the disability compensation. That’s the so-called “VA waiver” or “CRSC” (Combat- Related Special Compensation) terrain.
This rule applies to military retired pay, not to a FERS civilian annuity. If you are drawing both a military pension and VA disability, the offset rule applies. If you are drawing a FERS civilian annuity and VA disability, the offset rule does not apply — the FERS annuity and the VA compensation sit side by side, and there is no reduction.
Why the confusion is so common
Most federal employees I work with who have prior active-duty service also have a VA rating. Many of them are also eligible for military retired pay (because they served 20+ years or were medically retired). The mental model that “military pay and VA disability interact” is correct, but they map that mental model onto the FERS annuity by mistake. The mental model should be: military retired pay and VA disability interact; FERS civilian annuity and VA disability do not.
The case where the buyback really matters.
If you have already waived your military retired pay to receive VA disability — which is the move many veterans make because VA disability is tax-free — the buyback calculation can become significantly more favorable. The buyback deposit is calculated as a percentage of basic pay; the retired-pay waiver does not change that formula, but it does mean you are not double-dipping from the same service. Many employees who have made the waiver find that the buyback is one of the cleanest federal benefits moves they can make: the service is being used in only one place at that point, and the FERS annuity credit comes from that single use.
