Social Security for military retirees

Military basic pay is subject to Social Security tax, so every year of service builds an earnings record exactly as civilian employment does. A military pension does not reduce the benefit — a common worry, and an unfounded one for anyone whose service was covered employment.

What does complicate matters is that military retirees frequently claim at an unusual time, work in a second career while claiming, and have a spouse whose own record was interrupted by repeated moves. Each of those interacts with the rules in a way that is worth understanding before a decision is made that cannot be unmade.

How the benefit is computed

Two features of that formula matter specifically to a military career.

Thirty-five years is the denominator, and it does not shrink. A member who serves twenty years and works fifteen more has thirty-five years of record. A member who retires at forty-two and does not work again has twenty years of earnings and fifteen years of zeros in the average. Those zeros are expensive, and they are the strongest argument for a second career in any form.

The formula is steeply progressive. The first band is replaced at 90% and the top at 15%. That means additional earnings late in a high-earning career add relatively little, while filling in a zero year adds a great deal. A retiree working part-time is doing more for their benefit than the modest salary suggests.

Claiming age: what it actually costs

You may claim from 62. Your full retirement age depends on your birth year. Delaying past full retirement age earns delayed retirement credits until 70, after which there is no further increase and no reason at all to wait.

The earnings test, which catches second-career retirees

Claim before full retirement age while still working, and benefits are withheld above an annual earnings threshold. This routinely surprises military retirees, who are younger at retirement than most claimants and frequently working.

The earnings test disappears completely at full retirement age. From that point you may earn any amount with no withholding whatsoever, which for a retiree in a second career is frequently the decisive fact.

Spousal and survivor benefits

For military families these are often more consequential than the member’s own claiming decision, because a spouse’s earnings record is frequently interrupted — by repeated moves, by overseas assignments, by employment that could not follow the family.

A spousal benefit can pay up to half of the higher earner’s full retirement age amount, if that exceeds what the spouse earned on their own record. Claiming it early reduces it. Note the asymmetry: a spousal benefit does not earn delayed retirement credits, so there is no reason to delay a spousal claim past full retirement age.

A survivor benefit can pay up to the full amount the deceased was receiving or had earned. This is the one that reshapes the whole analysis for a couple.

Two rules that changed, and one that never applied

The Windfall Elimination Provision and the Government Pension Offset reduced benefits for people who had worked in employment not covered by Social Security. They were repealed by legislation enacted in early 2025. Because they applied for decades, a great deal of material written before then still describes them as current — and a retiree reading an older article may believe a reduction applies to them that no longer does.

Neither ever applied to ordinary military service in any case, because military basic pay is covered employment. They mattered to military retirees only where a second career was in non-covered employment, typically certain state and local government roles.

If you were told years ago that a pension would reduce your Social Security, that advice is worth re-checking. It may have been about these provisions, and it may no longer be true.

What to do

Read your Social Security statement at the administration’s own site. It shows your recorded earnings year by year and estimates your benefit at several claiming ages. Check the military years appear — errors are uncommon but not unknown, and they are far easier to correct with pay records you still hold.

Then make the claiming decision as a household rather than individually, with the survivor question explicit. It is the part most often decided by default, and it is the part that determines what one of you lives on for the years after the other is gone.
