No Social Security Tax Changes in Trump’s 'Big Bill'? What Retirees Need to Know
Eliminating taxes on Social Security benefits is missing from President Trump’s tax overhaul. Here’s why and what an alternative offering could mean for retirement taxes.


Now that President Donald Trump's landmark 2025 mega tax bill has become law, you may have noticed that a key campaign promise is noticeably absent.
During last year’s presidential campaign, Trump made several promises. One for retirees was to end federal taxes on Social Security benefits.
In several rallies and interviews, then-candidate Trump assured older adults that “SENIORS SHOULD NOT PAY TAX ON SOCIAL SECURITY!”

After being elected for his second term, he repeated the pledge in his 2025 State of the Union address: “I'm calling for no tax on tips, no tax on overtime, and no tax on Social Security benefits for our great seniors.”
Yet, Trump’s sweeping tax reform bill, dubbed the "One Big Beautiful Bill" (OBBB), makes no mention of eliminating taxes on Social Security benefits.
So, why didn't lawmakers cut taxes on Social Security in the legislation, and what are they offering instead? Here’s more of what you need to know.

Tax on Social Security benefits
Contrary to popular belief, Social Security benefits aren’t necessarily tax-free. Up to 85% of SS income can be subject to tax depending on an IRS formula known as “combined income” (It’s sometimes also called “provisional income.”)
- “Combined income” includes half of Social Security benefits, adjusted gross income (AGI), and any tax-exempt interest.
- If combined income exceeds $25,000 for individuals or $32,000 for couples, up to 50% of benefits can be taxed; above $34,000 (individuals) or $44,000 (couples), up to 85% can be subject to tax.
And…those thresholds haven’t been adjusted for inflation since the 1980s. So, as Social Security benefits and other incomes rise, more retirees each year find that their Social Security benefits are subject to tax to some extent.
According to the Social Security Administration, about 40% of recipients pay taxes on a portion of their benefits, compared to only 10% back in 1984.
The highest earners face the largest tax bills, but for most retiree households with lower income, Social Security benefits remain untaxed.
Why was a SS tax cut left out of Trump’s ‘big bill’?
There are several key reasons why the GOP mega reconciliation bill omits the Social Security tax repeal.
Budget Rules. First, Senate budget reconciliation rules prohibit significant changes to Social Security programs within a tax bill. One key hurdle was the “Byrd Rule,” named after the late Sen. Robert Byrd of West Virginia.
- The rule generally prohibits certain provisions in reconciliation bills.
- Essentially, while Congress can change various spending and revenue measures, it’s limited in its ability to alter Social Security benefits or funding.
So, the Byrd Rule made it procedurally unfeasible to include an SS tax repeal in Trump's “big bill.”
Fiscal Impact: Eliminating taxes on Social Security benefits would reduce federal revenue by an estimated $1.5 to $1.6 trillion over a decade, according to a Penn Wharton Budget Model. Some analyses suggest that such a loss could accelerate the depletion of the Social Security trust fund.
It’s also worth noting that, fresh from the June 2025 Trustees Report, the combined Social Security Trust Funds are now projected to be depleted by 2034, one year earlier than previously forecast.
At that point, incoming payroll taxes would only cover about 80% of scheduled benefits. That could lead to reduced payouts for all beneficiaries unless Congress acts.
The alternative: Bonus 2025 standard deduction over 65
Rather than eliminating taxes on Social Security, as Kiplinger has reported, the GOP’s main offering is a bonus $6,000 standard deduction for those 65 and older.
Regarding the bonus deduction, House Ways and Means Committee Chairman Rep. Jason Smith (R-Mo.) said in a statement, “Republicans are keeping President Trump’s promise to help seniors afford the cost of living through an expanded senior deduction in The One, Big, Beautiful Bill."
Here are some key points on how the enhanced extra standard deduction will work.
- The "bonus deduction" will be available from 2025 to 2028
- The full deduction will be available to those with modified adjusted gross income (MAGI) up to $75,000 (single filers) and $150,000 (joint filers), then phases out above those limits, completely phasing out at $175,000 (single filers) and $250,000 (joint).
- Eligible filers can take the bonus tax deduction whether itemizing or not.
- The bonus tax relief will stack on top of the existing extra standard deduction for those 65 and older.
Tax impact on retirees
But it’s important to note that the impact of any enhanced bonus standard deduction on people’s Social Security tax burden would be mixed. Here’s why:
For Lower-Income Retirees: Many already pay little or no federal income tax on their Social Security benefits, so the extra deduction may not offer much additional relief.
For Middle-Income Retirees: The deduction could help reduce taxable income enough to lower or eliminate taxes on Social Security benefits, especially for those close to the income thresholds. If the deduction brings a retiree’s combined income below the taxable threshold, they may see a reduction in the portion of benefits subject to tax.
Example: Consider a 67-year-old single retiree with $25,000 in Social Security and $18,000 from a retirement account. To determine if any Social Security is taxable, the IRS looks at "combined income." In this case, that’s $12,500 (half of $25,000) plus $18,000, totaling $30,500.
- This fictional retiree’s combined income is just above the $25,000 threshold where Social Security benefits start to be taxed.
- Under normal circumstances, a portion of their benefits would be included in taxable income.
However, the bonus GOP deduction would reduce their taxable income, potentially lowering their combined income calculation as well.
With OBBB changes to the bonus deduction and the regular standard deduction for 2025, their taxable income could drop enough to bring their combined income below the threshold or at least reduce how much of their Social Security is taxed.
For Higher-Income Retirees: Those with incomes above the phase-out limits will see little or no benefit from the deduction. As a result, their Social Security benefits would continue to be taxed at current rates.
Trump One Big Beautiful Bill: Bottom line
Despite campaign promises, the 2025 proposed tax bill hasn't delivered a Social Security tax cut. Instead, Trump’s new bill offers a temporary boost in the form of a bonus deduction for older adults.
In a report from the Bipartisan Policy Center, the proposed bonus deduction is described as “likely to benefit people who earn modest incomes,” but “the lowest-earning seniors already pay no federal income taxes, so they wouldn’t benefit. The highest earners make too much to qualify.”
But ending federal taxes on Social Security benefits would reduce government revenue by about $1.45 trillion over ten years. In comparison, the initially proposed $4,000 bonus over 65 deduction would cost roughly $200 billion in the same period.
So, according to several policy analyses, the deduction approach would save the federal government approximately $1.25 trillion compared to fully eliminating Social Security benefit taxes.
This story has been updated to clarify the phase-out rate for the bonus deduction.
