Yes, you may owe federal income tax on your Social Security benefits in 2026

Whether you pay tax on Social Security depends on your total income for the year, not on the amount of your benefit alone. The IRS uses a calculation called combined income — your adjusted gross income plus nontaxable interest plus half your Social Security benefit. If that number exceeds a threshold set by Congress, a portion of your benefit becomes taxable.

The thresholds have not changed since 1984. For 2026, a single filer with combined income over $25,000 may owe tax on up to 50 percent of benefits. A married couple filing jointly with combined income over $32,000 may owe tax on up to 85 percent of benefits. Married people filing separately almost always owe tax if they received any Social Security at all.

These thresholds are not adjusted for inflation, which means more people cross them each year. If you are already working, have a pension, or draw from retirement accounts, you are more likely to be taxed on your benefits in 2026 than you were five years ago.

Key Takeaways

  • You may owe federal income tax on Social Security if your combined income (wages, pensions, interest, plus half your benefit) exceeds $25,000 as a single filer or $32,000 as a married couple filing jointly.
  • The income thresholds that determine taxation have remained the same since 1984 and are not adjusted for inflation each year.
  • Up to 50 percent of your benefit may be taxable if you are below the higher threshold, and up to 85 percent if you are above it.
  • Some states also tax Social Security benefits, though most do not; check your state's tax rules separately from federal rules.

How the IRS calculates whether your benefits are taxable

The IRS does not look at your Social Security benefit in isolation. Instead, it adds together three things: your adjusted gross income (wages, self-employment income, taxable interest, taxable dividends, and taxable pensions), any nontaxable interest you earned, and half of your Social Security benefit for the year. That sum is your combined income.

If your combined income is $25,000 or less (single) or $32,000 or less (married filing jointly), you owe no federal tax on your Social Security. If it exceeds those amounts, the IRS taxes the lesser of two figures: either half your benefit, or 50 percent of the amount by which your combined income exceeds the threshold.

If your combined income exceeds a second, higher threshold — $34,000 for single filers or $44,000 for married couples filing jointly — the calculation becomes more complex. You may owe tax on up to 85 percent of your benefit. The IRS publishes a worksheet in the instructions to Form 1040 that walks through this calculation step by step.

Which types of income count toward the threshold

Wages and self-employment income count. Taxable interest, taxable dividends, and capital gains count. Distributions from traditional IRAs, 401(k)s, and other retirement accounts count as ordinary income. Pensions count. Rental income counts.

Nontaxable interest — such as interest from municipal bonds — also counts toward the threshold, even though you do not owe tax on that interest itself. This is one reason a retiree with a modest Social Security benefit can still end up owing tax on it.

Roth IRA withdrawals do not count toward the threshold, because they are not taxable income. Distributions from a Roth are treated as a return of your contributions first, then as earnings; only the earnings portion would count, and only if withdrawn before age 59½. Home sale gains excluded under the primary residence rule do not count. Gifts and inheritances do not count.

State taxes on Social Security in 2026

Most states do not tax Social Security benefits at all. As of 2026, thirteen states tax Social Security to some degree: Colorado, Connecticut, Delaware, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia.

Each state uses its own rules and thresholds. Some states exempt benefits entirely if your income falls below a certain level. Others tax a percentage of your benefit regardless of income. A few states tax only the portion that is taxable under federal rules. You will need to check your state's tax department website or speak with a tax preparer familiar with your state's rules.

Even if your state taxes Social Security, you may not owe state tax if your total income is low enough. State thresholds are often higher than federal thresholds, or the state may offer an exemption based on age or income.

What to do if you think you will owe tax on benefits

If you expect your combined income to exceed the threshold, you have two main options: adjust your withholding, or make estimated tax payments.

You can ask the Social Security Administration to withhold federal income tax directly from your benefit check. Complete Form W-4V and submit it to your local Social Security office or mail it to the address on the form. You choose the withholding rate: 7, 10, 15, or 22 percent of your benefit. This is the simplest method if you want to avoid a large tax bill at filing time.

Alternatively, if you have other income sources, you can adjust the withholding on those sources — for example, by changing your W-4 at work or adjusting estimated tax payments on self-employment income. This gives you more control over how much is withheld from each source.

How inflation affects your tax bill even though thresholds do not change

The $25,000 and $32,000 thresholds have been the same since 1984. Because they do not adjust for inflation, more people cross them each year as wages and other income rise. A person whose combined income was $24,000 in 2020 might have $26,000 in 2026 straightforward because of cost-of-living raises at work, even if their actual purchasing power has not changed.

This effect is sometimes called "bracket creep" or "threshold creep." It means that even if your life circumstances stay the same, you may owe tax on your Social Security in 2026 when you did not in previous years. Congress would need to pass new legislation to raise these thresholds or adjust them for inflation.

Frequently Asked Questions

Do I have to file a tax return if I only have Social Security income?

Not necessarily. If Social Security is your only income and it is below the filing threshold for your age and filing status, you do not have to file. However, if you have other income — wages, interest, dividends, or distributions from retirement accounts — you may need to file even if your Social Security benefit is modest. The IRS publishes filing requirement tables each year.

What if I work and receive Social Security at the same time?

Your wages count toward your combined income, which determines whether your Social Security is taxable. If you are under full retirement age and still working, Social Security also reduces your benefit by $1 for every $2 you earn above an annual limit (the limit changes each year). This reduction is separate from the tax calculation.

Can I reduce my combined income to avoid owing tax on Social Security?

You can lower your combined income by reducing taxable income sources — for example, by contributing more to a traditional IRA or 401(k), or by timing capital gains and losses. However, nontaxable interest (such as from municipal bonds) still counts toward the threshold, so switching to tax-free bonds does not help. Speak with a tax professional about strategies that fit your situation.

Will the thresholds change before 2026?

Congress would have to pass legislation to change the thresholds. As of now, no bill has been signed into law that would raise or adjust them for 2026. You should check the IRS website closer to tax time to confirm whether any changes have been made.
