He Worked 600 Hours of Wildfire Overtime at 64. He Thought the New Tax Break Would Protect His Social Security Check. He Was Wrong.

Picture a 64-year-old on a seasonal wildfire mitigation crew in the Mountain West. He filed for Social Security at 62 to help cover the mortgage. Then a brutal fire season hit, and the overtime started piling up. By August, he had logged roughly 600 hours at time and a half. A buddy at the fire cache mentioned the new federal “no tax on overtime” deduction. He assumed the extra pay would be protected from Social Security’s earnings test. It was not.

The tax break follows part of his overtime onto his federal return. Social Security follows the entire paycheck.

“No Tax on Overtime” Does Not Mean All Overtime Is Deductible

Public Law 119-21, commonly known as the One Big Beautiful Bill Act, created a temporary deduction for qualified overtime compensation through 2028. Despite the “no tax on overtime” label, generally only the overtime premium covered by the Fair Labor Standards Act qualifies. If someone earns $20 an hour and receives $30 for overtime, the deductible portion is usually the extra $10. The deduction is capped at $12,500 per worker, or $25,000 for a married couple filing jointly, and phases out at higher incomes.

The full paycheck remains subject to Social Security and Medicare payroll taxes. The deduction lowers federal taxable income; it does not reduce the wages Social Security applies to the retirement earnings test.

Social Security Counts the Whole Paycheck

Anyone collecting retirement benefits before full retirement age (FRA) remains subject to an annual earnings limit. In 2026, a beneficiary who stays below that threshold all year can earn up to $24,480. Above that amount, Social Security generally withholds $1 in benefits for every $2 of excess earnings. The agency starts with wages, not taxable income after deductions. Regular pay counts. Overtime counts. A deduction claimed later on the tax return does not reduce either number.

Suppose the firefighter earns $20,000 in regular seasonal wages and another $18,000 from 600 overtime hours at $30 each. Assuming all the premium pay qualifies, his overtime deduction might be $6,000. The IRS gives him a deduction for that $6,000. Social Security still sees $38,000 in wages. That puts him $13,520 above the 2026 earnings limit and can cause approximately $6,760 in retirement benefits to be withheld. The tax break worked exactly as written. It simply worked on a different calculation.

The Withholding Is Temporary, but the Missing Checks Are Real

Claiming Social Security at age 62 can shrink the starting benefit by approximately 30% compared with waiting until FRA. A heavy earnings year can then temporarily interrupt that already-reduced stream of income. The withheld benefits are not permanently forfeited. At full retirement age, Social Security recalculates the monthly amount to credit months in which benefits were withheld. That produces a larger check going forward, not a refund of the missing payments.

Until then, the household has to absorb the lost cash flow. The worker also cannot simply pause his benefits at 64 and begin earning delayed retirement credits. Voluntary suspension generally becomes available only at FRA. Withdrawing an earlier claim is usually limited to the first 12 months and requires repayment of benefits already received.

What to Do Before the Next Overtime Push

Two calculations now matter, and they should be kept separate:

1. Add expected regular pay and the full amount of overtime. Compare the total with Social Security’s current earnings limit, then update the agency if the estimate has changed substantially. That can prevent an unexpected overpayment notice later.
2. Calculate only the qualifying overtime premium for the federal deduction. Confirm that the employer’s records identify the amount and that the work qualifies under the Fair Labor Standards Act.

The new deduction can make overtime less expensive at tax time. It cannot make those wages disappear from Social Security. The IRS gives the premium pay a break; the earnings test still counts the shift.
