The One Big Beautiful Bill Act (OBBA) was a massive budget reconciliation bill signed into law by President Trump in July 2025. Ever since, some have claimed that OBBA ended taxes on seniors’ Social Security payments. But the reality is a bit more complex. The Act includes a new $6,000 tax deduction ($12,000 for married filing jointly) that can be claimed by seniors for 2025. However, it does not eliminate Social Security taxes for some high-income seniors.
One reason the deduction may not help high-income seniors is that it begins phasing out when a taxpayer earns over $75,000 in income ($150,000 for married filing jointly (MFJ)). The deduction amount drops to zero for seniors earning $175,000 or more ($250,000 MFJ). The $6,000 deduction is also not available to retirees who begin taking their Social Security retirement benefits before 65. The new tax deduction is also temporary, expiring at the end of the 2028 tax year.
However, the new deduction is expected to eliminate Social Security taxes on retirement benefits for roughly 88% of recipients, according to the White House Council of Economic Advisors. Before the OBBBA, about 50% of recipients paid taxes on their benefits. The remaining 12% of seniors should see smaller federal income tax bills in April, as they may pay at least some tax on their Social Security benefits.
The deduction can be claimed by taxpayers who itemize and those who claim the standard deduction. The $12,000 deduction for married filing jointly (MFJ) can only be claimed if both spouses are age 65 or older.
An Additional Deduction for Seniors
While the new deduction in the OBBBA is often called the “senior deduction,” it is actually an additional senior deduction. Seniors claiming the standard deduction could already claim a higher amount than younger taxpayers under the 2017 Tax Cuts and Jobs Act.
For 2025, the standard deduction for seniors is $17,750, and $34,700 for MFJ who are both 65 or older. Adding the additional senior deduction in the new law to the standard deduction for seniors raises the deduction to $23,750 for individuals and $46,700 for married joint filers.
How Is Social Security Taxed?
While the tax law changes in the OBBBA added a new $6,000 for taxpayers 65 or older, it did not change how Social Security is taxed. Beneficiaries may still be taxed on up to 85% of their Social Security income. That was the rule in place before the OBBBA. The new deduction reduces the total of a senior’s taxable income from all sources (including Social Security).
Whether Social Security benefits are taxable and the tax rate on a tax return is found using the taxpayer’s modified adjusted gross income (MAGI). MAGI is calculated by taking a taxpayer’s adjusted gross income and adding further deductions and exclusions. The IRS uses MAGI to determine eligibility for tax benefits. The taxable amount of Social Security is based on your filing status and calculated using the following thresholds:
Single filers:
- 0% for MAGI under $25,000
- 50% for MAGI of $25,000 up to $34,000
- 85% for MAGI of $34,000 or more
Married taxpayers filing jointly:
- 0% for MAGI under $32,000
- 50% for MAGI of $32,000 up to $44,000
- 85% for MAGI of 44,000 or more
Phase-Out for High-Income Seniors
Taxpayers 65 or older with a MAGI of over $75,000 ($150,000 MFJ) are eligible to claim the entire $6,000 deduction. For every dollar of a taxpayer’s MAGI over that amount, the deduction is reduced by 6%. It phases out entirely for single taxpayers with MAGI of $175,000 ($250,000 MFJ). In other words, for each $1 in MAGI over the threshold, the deduction decreases by six cents. Fortunately, tax software and tax professionals will perform this calculation for you.
Maximizing the Deduction
High-income seniors receiving Social Security and other income may want to restructure their finances so they can take full advantage of the additional senior deduction. Consulting with a local tax attorney can help structure payments from retirement plans or IRAs to stay under the phase-out threshold. Restructuring payment schedules can also reduce your tax rate by placing you in a lower tax bracket.
A tax lawyer is also skilled at identifying tax breaks, tax credits, and tax exemptions that offer additional opportunities for savings. An attorney can help you take advantage of other tax benefits in the OBBBA, such as the deduction for interest on new car loans and Trump accounts.
