Military buyback and FERS military retirement: what changes?
A FERS military service deposit and military retired pay answer different questions. A deposit may make qualifying service creditable in FERS, but receiving military retired pay can trigger separate crediting or waiver rules. Active-duty and Reserve or Guard records are not interchangeable. Verify the pay authority, service period, and waiver effect with OPM, DFAS, and your agency.
Sources and guidance last reviewed: September 7, 2026
FERS creditA deposit may add service credit
It does not create civilian service or replace the five years of civilian service needed to vest in FERS.
Military payPay type controls the question
Active-duty retired pay and Reserve or Guard retirement authorities need different record checks.
VA compensationKeep it in its own lane
VA compensation is not the same as military retired pay; ask the VA or DFAS about any separate interaction.

The decision boundary
Why do active-duty and Reserve or Guard records branch differently?
OPM’s controlling rule: If you receive military retired pay, the same military service generally cannot receive credit in your FERS annuity computation unless the retired pay was awarded for a qualifying combat or instrumentality-of-war service-connected disability, or under Title 10, Chapter 1223 for a reserve-component retirement. Outside those exceptions, OPM says you may elect to waive military retired pay and must also complete the required post-1956 military service deposit before separating from your agency.
Active-duty retired pay: general rule
Crediting the same service generally requires waiving military retired pay unless one of OPM’s stated exceptions applies.
A FERS deposit and a retired-pay waiver are separate requirements; making the deposit does not itself waive retired pay.
Confirm the exact service periods and retired-pay authority before electing a waiver.
Reserve or Guard retirement: Chapter 1223 exception
OPM lists retired pay under Title 10, Chapter 1223 as an exception to the general retired-pay restriction.
Still separate active-duty orders from drills, inactive duty, and retirement points; the exception does not make every period automatically creditable.
Mixed records require a period-by-period review of what service the FERS deposit would cover.
Disability-retired-pay exception: OPM also lists retired pay awarded for a service-connected disability incurred in combat with an enemy or caused by an instrumentality of war in the line of duty during a period of war. A disability label alone does not establish that exception; verify the award basis.
Five-year vesting reminder: Credited military service may affect an annuity calculation or a service test, but it does not replace the five years of civilian service generally needed to vest in a FERS annuity. Confirm your civilian record with OPM.

What stays separate
What should you keep out of the buyback-versus-waiver shortcut?
VA compensation
VA disability compensation is a separate VA benefit, not military retired pay. This page does not decide how a retired-pay election, CRDP, CRSC, or a VA award applies to your situation. Ask the responsible agency before relying on a general statement.
Survivor and related benefits
A change to military retired pay can raise separate questions about survivor coverage, premiums, health coverage, and other privileges. Include your survivor elections and written plan terms in the DFAS conversation; do not infer them from a FERS deposit.
Worked example: why labels are not enough
Assumptions: A federal employee has an active-duty DD-214, receives a monthly military payment, and has been told “buyback may be available.”
What follows: The employee can ask about a FERS deposit, but cannot infer from the label “retired pay” whether a waiver is required. The next step is to identify the pay authority and have OPM or the agency benefits office review the exact service period. No dollar outcome is shown because neither pay amount nor eligibility is established.
Scope
Who is this page for, and what can it not determine?
For
FERS employees with prior military service.
Veterans deciding which records and agencies to contact.
Reserve or Guard retirees who need to identify the governing authority.
Not for
Replacing OPM, DFAS, agency HR, VA, or legal advice.
Calculating military retired pay or inventing a FERS outcome.
Making an irreversible waiver, survivor, tax, or benefits election.
This page cannot determine: your deposit amount, whether a specific period is creditable, whether a waiver is required, eligibility for military retired pay, VA program interaction, survivor consequences, or the best financial choice for your household.
