Military Buyback and Surviving Spouse Benefits: What Happens After Death

Why Your Spouse's Annuity Depends on Your Military Deposit

When a federal retiree dies, OPM pays a survivor annuity to the eligible spouse — but only based on creditable service that was properly completed before separation. If you retire without finishing your military service deposit, those military years are excluded from your annuity computation. That reduced base annuity is then what OPM uses to calculate your spouse's survivor benefit.

The financial chain is direct: an incomplete military deposit reduces your annuity, which reduces your survivor annuity, which reduces your spouse's income for the rest of their life after you die.

How Survivor Annuity Is Calculated

Under FERS, the standard survivor annuity for a spouse is 50% of the retiree's unreduced annuity (or 25% if the retiree elected the partial survivor benefit at retirement). The annuity used in this calculation is the full earned amount — before any reduction the retiree may have elected for the survivor benefit itself.

Here is a concrete example:

With military buyback (20 years total service, age 62, high-3 of $95,000): Annuity: $95,000 × 20 × 1.1% = $20,900/year Survivor annuity (50%): $10,450/year

Without military buyback (16 years civilian only, age 62, high-3 of $95,000): Annuity: $95,000 × 16 × 1.0% = $15,200/year Survivor annuity (50%): $7,600/year

The difference is $2,850 per year in survivor benefits — every year your spouse outlives you. Over 15-20 years of widowhood, that gap compounds to $42,750-$57,000 in lost income for your surviving spouse.

Under CSRS, the maximum survivor annuity is 55% of the unreduced annuity. The same logic applies: a higher base annuity from credited military service means a higher survivor annuity.

Can a Spouse Complete the Deposit After the Employee Dies?

No. The statutory deadline is absolute: the military service deposit must be paid in full before the employee's date of separation from federal service. If the employee dies while still employed (death in service), the deposit must have been completed before the date of death.

There is no provision in 5 U.S.C. §§ 8334 or 8422 for a surviving spouse, executor, or estate representative to complete an unpaid military deposit after the employee's death. The window closes permanently.

This is one of the hardest rules in the federal retirement system. An employee who was actively paying down their deposit through payroll deductions but dies or is forced to separate before the balance reaches zero does not get partial credit. Either the deposit is paid in full, or the military service is excluded entirely from the annuity computation.

Death-in-Service Scenarios

If a federal employee dies while still employed and the military deposit was fully paid, the military years count toward the annuity used to calculate the survivor benefit. The employee's total creditable service (civilian plus military) determines both eligibility for the survivor annuity and the amount.

For FERS, a surviving spouse is eligible for the basic employee death benefit (one-time lump sum) plus a survivor annuity if the deceased employee had at least 10 years of creditable service — including bought-back military time. If the employee had 8 years of civilian service and 3 years of completed military buyback, the total of 11 years meets the 10-year threshold.

If the military deposit was not completed, those 3 years do not count. The employee's creditable service drops to 8 years, which falls below the 10-year minimum for a FERS survivor annuity. In that scenario, the spouse receives only the lump-sum death benefit — not the ongoing monthly annuity.

Planning for the Worst Case

The interaction between military buyback and survivor benefits creates a planning imperative that goes beyond the retiree's own financial interest. Completing the deposit is not just about your pension — it is about your spouse's financial security if you die first.

Two specific actions reduce the risk:

Start early. The biggest threat is not the deposit amount — it is the processing timeline. If you are making payroll deductions and die or are forced to retire before the balance is cleared, the military years are lost. Starting the deposit process years before retirement gives you time to pay it off completely.

Consider a lump-sum payment. If you have the funds, a one-time payment through Pay.gov eliminates the risk of an incomplete balance. A $5,000 deposit paid in a single transaction is done — there is no outstanding balance that could be caught by an unexpected separation or death.

The survivor annuity impact alone often justifies the deposit cost. Even if you are ambivalent about the annuity increase for yourself, the effect on your spouse's income after your death is a separate, often larger, financial consideration.

The Military Buyback Guide for Federal Employees includes a survivor benefit impact worksheet that calculates the difference in your spouse's annuity with and without the military service credit, so you can see the full financial picture before deciding.
