Trump Promised No Tax on Social Security. Two Years Later, Retirees Are Still Paying It.

Nearly two years after Donald Trump made "no tax on Social Security" a campaign line, retirees are still getting taxed on their benefits. The One Big Beautiful Bill Act, which Trump signed in July 2025, "does not include this provision," according to the Tax Foundation.

What it includes instead is a temporary $6,000 tax deduction for seniors 65 and older, available only from 2025 through 2028, according to the IRS. It phases out for individuals with modified adjusted gross income above $75,000, or $150,000 for joint filers.

That's a deduction, not an exemption. It shrinks taxable income for some seniors enough to dodge or reduce Social Security taxation under the existing formula, but it doesn't touch the underlying tax code provision that makes benefits taxable in the first place, according to FinanceBuzz.

How the actual tax math works

Social Security taxation depends on "provisional income," which is modified adjusted gross income plus half of annual benefits. Single filers with provisional income between $25,000 and $34,000 can owe tax on up to 50% of benefits. Above $34,000, up to 85% can be taxed. Joint filers face the same structure at $32,000 and $44,000, according to FinanceBuzz.

The $6,000 deduction can push some retirees below those thresholds. A single filer at $30,000 in provisional income who claims the full deduction drops to $24,000, clearing the tax entirely. But the Tax Policy Center estimates the deduction will "benefit fewer than half of older adults," because plenty of retirees either don't qualify due to income or don't owe much Social Security tax to begin with.

The math that should worry retirees more

This deduction isn't free. It cuts federal revenue that flows toward Social Security by roughly $91 billion over its four-year run, according to Joint Committee on Taxation analysis cited by the Peter G. Peterson Foundation.

That revenue hit, combined with other OBBBA tax cuts, moved up the projected insolvency date for the Social Security trust fund to 2032, one year earlier than previously projected, according to the Bipartisan Policy Center. The Committee for a Responsible Federal Budget projects that when the trust fund runs dry, benefits could face a roughly 24% across-the-board cut unless Congress acts.

That 2032 date lines up with what Senate Democrats have been hammering. At an August 5 Senate Finance Committee hearing, Senator Elizabeth Warren cited the 2026 Trustees Report showing the trust fund can only pay 78% of promised benefits after 2032, a 22% cut. AARP's Nancy LeaMond told the committee that cut would run about $400 a month for seniors on minimum benefits.

Warren's fix, laid out in a June 2026 op-ed she co-wrote with Republican Senator Bernie Moreno, is lifting the payroll tax cap so high earners pay Social Security tax on 100% of their income like everyone else does. Rebecca Vallas of the National Academy of Social Insurance testified that move would generate enough revenue to protect current benefits and possibly strengthen them.

That's one proposal from one side of the aisle, and it hasn't passed. Nobody in these hearings has offered a bipartisan alternative that's cleared committee. The insolvency clock keeps running regardless of who's right about the fix.

COLA numbers are about to shift the conversation

Separately, the Bureau of Labor Statistics is set to release the July 2026 Consumer Price Index report next week, the first of three inflation readings that determine the 2027 cost-of-living adjustment, according to Newsweek. The Senior Citizens League already projects a 3.8% COLA for 2027, up from the 2.8% adjustment that took effect in 2026.

Alex Beene, a financial literacy instructor at the University of Tennessee at Martin, told Newsweek the CPI-W reading is what actually drives the number, and cautioned that "a larger COLA is not automatically better. It usually reflects higher inflation, and any gain can be offset by rising living expenses."

The Social Security Administration won't announce the official 2027 COLA until October. Only one of three required quarterly readings will be in hand after next week's report, so the 3.8% projection could still move.

None of this changes the tax picture. A bigger COLA means bigger benefit checks, which for many retirees means higher provisional income, which can push more of their Social Security into taxable territory even with the temporary deduction in place. Retirees banking on "no tax on Social Security" got a narrow, temporary carve-out instead, one that expires in 2028, while the trust fund's insolvency date moved closer, not further away.

The open question is whether Congress does anything with either problem before 2028, when the deduction lapses, or before 2032, when the shortfall hits. Right now there's no bill on the floor addressing either deadline.
