What is the income limit for the senior deduction?

It phases out at 6% of modified AGI above $75,000 (single) or $150,000 (married filing jointly). It is fully gone at about $175,000 single or $350,000 for a couple both 65+.

Do I have to itemize to get the senior deduction?

No. The senior bonus deduction is available whether you take the standard deduction or itemize, and it stacks on top of the existing extra standard deduction for those 65 and older.

Last updated: June 2026 By the FedCalc Editorial Team · checked against IRC §151(d)(5) & IRS guidance

The short answer: OBBBA did not make Social Security tax-free. It created a $6,000 bonus deduction for each person age 65+ ($12,000 if a married couple are both 65+), for 2025–2028. It lowers taxable income — for many seniors that wipes out the tax on their benefits, but it is a deduction, not an exemption, and it phases out at higher incomes. Confirmed

What the senior deduction actually is

The 2025 One Big Beautiful Bill Act added a temporary bonus deduction for older taxpayers under IRC §151(d)(5). It is $6,000 per qualifying individual age 65 or older, or up to $12,000 for a married couple filing jointly where both spouses are 65+. It applies for tax years 2025 through 2028, then expires.

It is not the same as making Social Security tax-free. Instead it reduces your taxable income, which for many middle-income retirees reduces or eliminates the federal tax they would owe on their benefits. It works whether you itemize or take the standard deduction, and it stacks on top of the existing extra standard deduction seniors already get.

Who qualifies

You (or your spouse) are age 65 or older by the end of the tax year.
You have a valid Social Security number; married taxpayers must file jointly (married filing separately is excluded).
Your income is below the phase-out ceiling for your filing status.

Note: this calculator's "married filing jointly" option assumes both spouses are 65+ ($12,000). If only one spouse qualifies, use the single option to model the $6,000 amount.
