His Military Pension Didn’t Shrink His Social Security. His New Defense-Plant Paycheck Could.

Explainer article about how Social Security’s retirement earnings test applies to a hypothetical Navy chief who retired at 42, drew a military pension, and now—at age 63—is considering a $30/hour defense-contractor job.

About the rule

Social Security’s retirement earnings test applies only to people collecting benefits before full retirement age (FRA), which is 67 for anyone born in 1960 or later. Beginning with the month FRA is reached, the test disappears and a retiree can earn any amount without benefit withholding.

The test counts only wages from a job and net earnings from self-employment. It ignores pensions, annuities, investment income, interest, dividends, veterans benefits, and military retirement pay.

Impact of a $30-an-hour job

In 2026, someone below FRA all year can earn up to $24,480 before the earnings test begins. Above that limit, Social Security withholds $1 in benefits for every $2 of excess earnings.

• Full-time work at $30/hour for a full year yields approximately $62,400.
• That is $37,920 above the $24,480 limit, producing $18,960 in benefit withholding.
• With a $2,000 monthly Social Security benefit, most of that year’s checks could disappear.

The calendar year in which FRA is reached receives more forgiving treatment: a higher earnings limit of $65,160 applies, and only $1 in benefits is withheld for every $3 earned above it before the birthday month. Earnings beginning with the month FRA is reached do not count at all.

What “withheld” really means

Withheld benefits are not refunded later as a lump sum. At full retirement age, Social Security recalculates the early-claim reduction and gives credit for months when benefits were fully withheld, raising the monthly payment going forward. The new wages may also replace a lower year in the highest-35 earnings record, further increasing the benefit.

Tax considerations

The pension is invisible to the earnings test but may still trigger federal income tax on up to 85% of Social Security benefits once combined income crosses IRS thresholds. This is a separate tax calculation, not a benefit reduction.

Key steps before accepting the job

• Estimate the wages expected during the calendar year; exclude military pension, VA benefits, investment income, and IRA withdrawals from the earnings-test calculation.
• Report the wage estimate to Social Security and update it if hours or pay change to avoid overpayment notices.
• Compare the wages with the benefits temporarily withheld, taxes, commuting costs, and any employer retirement contribution.
