At 73 and Still Working Full Time, Can You Avoid Social Security Taxes?

A 73-year-old worker earning more per week than at any previous point in their career is confronting a financial puzzle that stumps many older Americans: whether continued full-time employment triggers federal income taxes on Social Security benefits — and whether anything can be done to reduce that burden.

The concern is well-founded. Social Security benefits become partially taxable when a recipient's "combined income" — a formula that adds adjusted gross income, nontaxable interest, and half of Social Security benefits — exceeds certain IRS thresholds. For individuals, up to 50% of benefits may be taxable above one threshold, and up to 85% above a higher one. Full-time wages push most working seniors well past both limits.

For someone in this situation, the challenge is especially acute because wage income is largely fixed and difficult to reduce without changing work arrangements. However, financial planners typically point to several legal strategies: maximizing contributions to tax-deferred accounts like a traditional 401(k) or IRA to lower adjusted gross income, reviewing whether any income can be timed or shifted, and ensuring proper tax withholding or quarterly estimated payments are in place to avoid a surprise bill at filing time.

The broader situation reflects a growing reality in the U.S. economy, where more Americans are working deeper into retirement age — either by choice or necessity. As wages rise and Social Security payments increase with cost-of-living adjustments, more seniors find themselves caught in a tax structure that was designed decades ago and has never been updated for inflation. Tax planning, rather than tax avoidance, becomes the essential tool for navigating this landscape.
