Is Social Security Taxable? How Your Benefits Are Taxed

Yes — Social Security benefits can be federally taxable, but most people pay tax on only a portion, and many pay nothing at all. Whether yours are taxed comes down to a figure called your combined income. Here is how it works.

The quick answer

Depending on your income, 0%, up to 50%, or up to 85% of your Social Security benefits can be counted as taxable income. Important: "up to 85%" is not an 85% tax rate — it means at most 85% of your benefits get added to your taxable income, which is then taxed at your ordinary rate.

How "combined income" is calculated

The IRS uses a measure called combined income (sometimes "provisional income"):

Combined income = your adjusted gross income (AGI) + any nontaxable interest + half of your Social Security benefits.

The thresholds (2026)

These breakpoints are set in law and are not adjusted for inflation, so they have been the same for decades:

Single / head of household

• Under $25,000 — benefits generally not taxed
• $25,000–$34,000 — up to 50% taxable
• Over $34,000 — up to 85% taxable

Married filing jointly

• Under $32,000 — not taxed
• $32,000–$44,000 — up to 50% taxable
• Over $44,000 — up to 85% taxable

Because the thresholds never rise with inflation, more retirees cross them over time.

The new senior deduction (through 2028)

A 2025 law (the One Big Beautiful Bill Act) added a temporary bonus deduction of up to $6,000 per person age 65 or older ($12,000 for an eligible couple), in effect through tax year 2028. It does not exempt Social Security itself — it is an extra deduction that lowers your overall taxable income, which can keep more households below the combined-income breakpoints and reduce or eliminate the tax on their benefits. It phases out at higher incomes and expires after 2028, so treat it as a planning window, not a permanent change.

State taxes

Most states do not tax Social Security benefits, and the number that do keeps shrinking. A minority still do, often with their own income exemptions — check your state's rules.

How to pay, if you owe

You can have federal tax withheld from your benefits with Form W-4V, or pay quarterly estimated taxes. Withholding can prevent a surprise bill at filing time.
