Social Security benefits tax threshold, Digi Mart USA News: Many Americans expect to collect Social Security in retirement, but once monthly checks begin, some retirees face an unexpected tax bill. According to a 24/7 Wall St.
personal finance article published November 3, 2026, Social Security benefits can be taxable in retirement, even though the benefits are primarily funded through taxes paid on wages.
The article reports that President Trump sought to eliminate taxes on Social Security, but that the limited-time $6,000 deduction included in the One Big Beautiful Bill Act temporarily spared most seniors rather than eliminating the tax. The article states that the thresholds for Social Security taxation have not changed in decades, so more seniors could become subject to these taxes as benefits rise over time.
Social Security benefits are taxed based on provisional income, calculated as adjusted gross income, plus tax-exempt interest income, plus 50% of annual Social Security benefits. For single tax filers, provisional income of $25,000 or more may make up to 50% of benefits subject to federal income tax.
For married couples filing jointly, the figure is $32,000.
According to the article, these limits were set in 1984 and have not been adjusted. A second tier applies at $34,000 for single filers and $44,000 for joint filers, where up to 85% of benefits may be taxed.
The article notes that moderate earners could face these taxes because of the low thresholds, and that annual cost-of-living adjustments may push provisional income higher over time.
The article explains that Social Security relies in part on revenue from taxes on benefits, which is one reason Congress has not updated the formula. The article states that the program faces a major funding shortfall that could lead to benefit cuts, and that changing the provisional income formula could worsen that situation.
It advises retirees who do not currently owe taxes on their benefits to plan for the possibility that they may owe taxes as their benefits grow.
