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

Summarized from MarketWatch.com - Top Stories

A 73-year-old working professional worries about an unexpected tax bill on Social Security benefits. Here's what the rules actually mean for high earners.

For older Americans who continue working well into their seventies, the financial picture can be surprisingly complicated. When earned income combines with Social Security benefits, the IRS applies a formula that can make a significant portion of those benefits taxable — a reality that catches many retirees off guard, even those who are financially savvy.

The core issue is what the Social Security Administration and the IRS call "combined income" — a calculation that adds adjusted gross income, nontaxable interest, and half of Social Security benefits together. Once that figure crosses certain thresholds, up to 85% of Social Security benefits can become subject to federal income tax. For someone still pulling in a full-time salary at 73, those thresholds are almost certainly being exceeded, meaning the bulk of their benefits are likely taxable.

Unlike some tax burdens, this one does not simply disappear with careful planning. The thresholds — $25,000 for single filers and $32,000 for married couples filing jointly — have not been adjusted for inflation since they were established decades ago, which means a growing share of beneficiaries find themselves caught in the net each year. Working longer and earning more, while financially beneficial, accelerates that exposure rather than reducing it.

That said, strategic use of tax-advantaged accounts, timing of other income sources, and potential Roth conversions in earlier years can soften the blow for future retirees still in the planning phase. For someone already 73 and earning a strong salary, the more realistic goal may be accurate withholding or quarterly estimated tax payments to avoid penalties — rather than eliminating the tax liability entirely. Knowing what to expect, and planning for it, is ultimately more valuable than searching for an escape hatch that may not exist.

Frequently Asked Questions

Q.How much of my Social Security benefits can be taxed if I'm still working?

Up to 85% of your Social Security benefits may be subject to federal income tax if your combined income exceeds IRS thresholds — $25,000 for single filers or $32,000 for married couples filing jointly.

Q.What counts as combined income for Social Security tax purposes?

Combined income is calculated by adding your adjusted gross income, any nontaxable interest, and half of your Social Security benefits together. If that total exceeds the IRS thresholds, a portion of your benefits becomes taxable.

Q.Can a 73-year-old who works full time avoid taxes on Social Security?

It is very difficult to avoid taxes on Social Security benefits while earning a full-time salary at 73, since earned income typically pushes combined income well above IRS thresholds. The more practical goal is accurate withholding or quarterly payments to prevent unexpected tax bills.
