Social Security is taxed only if your other income is high enough

Whether you pay federal income tax on your Social Security depends on your combined income — not just what Social Security sends you. The IRS counts half your Social Security benefits plus all your other income (wages, pensions, interest, dividends). If that total exceeds a threshold, you owe tax on a portion of your benefits.

The thresholds are $25,000 for single filers and $32,000 for married couples filing jointly. These numbers have not changed since 1984, so they catch more people each year as wages and benefit amounts rise. If you stay below the threshold, you pay nothing on your Social Security.

State taxes work differently. Most states do not tax Social Security at all. A handful — including Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont — tax it under their own rules, which vary by age and income. Check your state's tax agency website for the exact rules where you live.

Key Takeaways

  • You only owe federal tax on Social Security if your combined income (half your benefits plus other income) exceeds $25,000 single or $32,000 married filing jointly.
  • The IRS taxes up to 85 percent of your benefits if your combined income is very high, but most people who pay tax pay on only 50 percent of their benefits.
  • Most states do not tax Social Security, but eleven states have their own rules — check your state tax agency to know whether you owe state tax.
  • The Social Security Administration sends Form SSA-1099 in January showing what you received; use this to fill out your federal return.

How the IRS calculates what portion is taxable

The calculation has two tiers. If your combined income is between $25,000 and $34,000 (single) or $32,000 and $44,000 (married), you pay tax on up to 50 percent of your benefits. If your combined income exceeds those upper thresholds, you pay tax on up to 85 percent of your benefits.

The math is not straightforward — the IRS uses a worksheet to determine the exact amount. But the practical result is this: if you are just barely over the threshold, you will owe tax on a small slice of your benefits. If you are well over it, you will owe tax on most of them.

Example: You are single, receive $20,000 in Social Security, and have $10,000 in pension income. Your combined income is $20,000 (half of $20,000 Social Security) plus $10,000 = $30,000. You are $5,000 over the $25,000 threshold. You would owe tax on up to $2,500 of your benefits (50 percent of the overage). You would report this on Form 1040 and Schedule 1.

What counts as income for this calculation

Combined income includes wages, self-employment income, pensions, annuities, interest, dividends, capital gains, rental income, and distributions from retirement accounts. It also includes tax-exempt interest from municipal bonds — a rule that surprises many people.

What does not count: Supplemental Security Income (SSI), Medicaid, food stamps, or housing information. These do not push you over the threshold. Likewise, money you withdraw from a Roth IRA (after the account has been open five years) does not count as income for this purpose, though withdrawals from traditional IRAs do.

If you are married and file separately, the threshold drops to zero — meaning you will owe tax on your benefits almost no matter what. The IRS discourages married couples from filing separately for this reason.

Withholding and estimated tax payments

The Social Security Administration does not automatically withhold federal income tax from your benefits. You have to request it. If you want taxes withheld, fill out Form W-4V and send it to your local Social Security office or submit it online through your my Social Security account.

You can choose to have 7, 10, 12, or 22 percent of your monthly benefit withheld. Many people choose 10 percent as a middle ground. If you do not request withholding and you expect to owe tax, you may need to make quarterly estimated tax payments to avoid a penalty.

If you have other income (wages, a pension, rental property), your employer or pension provider may already be withholding enough to cover your Social Security tax. Check your year-end pay stub or 1099 to see whether you are on track.

Reporting Social Security on your tax return

In January, the Social Security Administration mails Form SSA-1099 showing the total you received in the previous year. Use this form to fill out your federal return. You will report your Social Security on Form 1040, lines 5a and 5b, and then use the IRS worksheet to calculate how much is taxable.

If you use tax software (TurboTax, H&R Block, TaxAct), the program will walk you through the calculation. If you file by hand or with a tax preparer, bring the SSA-1099 and your other income documents (W-2s, 1099s, bank statements showing interest).

You do not have to file a return at all if your income is below the standard deduction for your age and filing status. For 2024, the standard deduction is $14,600 for single filers age 65 and older. If your combined income is below that, you have no federal filing requirement — though you may still want to file to claim the Earned Income Tax Credit or other refundable credits.

Planning to reduce taxes on Social Security

If you are close to the income threshold, a few moves can lower your combined income. Delaying Social Security by a year or two reduces the amount you receive annually, which lowers your combined income in the years you wait. This works best if you are still working and can afford to wait.

Roth conversions (moving money from a traditional IRA to a Roth) increase your income in the year of conversion, which can push you over the threshold temporarily. But in future years, Roth withdrawals do not count as income, so the strategy can pay off long-term. This requires careful year-by-year planning.

If you have significant tax-exempt interest from municipal bonds, moving that money to taxable bonds or stocks reduces your combined income for Social Security purposes — though it may increase your overall tax bill depending on your tax bracket.

State tax treatment of Social Security

Eleven states tax Social Security under their own rules. Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont all have state income tax on benefits, though most offer exemptions or deductions based on age or income level.

For example, Kansas taxes Social Security but exempts it for residents age 55 and older. Minnesota taxes it but exempts it for residents age 62 and older. Connecticut taxes it but exempts it for residents age 60 and older with income below a certain threshold. Check your state's Department of Revenue or tax agency website for the exact rules.

If you live in a state that taxes Social Security and you are considering moving, this can be a significant factor. Some retirees move to states with no income tax (Florida, Texas, Wyoming) or states that exempt Social Security (most of the country) to reduce their overall tax burden.

Frequently Asked Questions

Do I have to pay tax on Social Security if I am still working?

Yes, if your combined income (including wages) exceeds the threshold. Wages count as income for this calculation. If you are working and receiving Social Security, your combined income is likely to be high enough that some of your benefits are taxable.

What if I did not request withholding and I owe tax?

You can file an amended return (Form 1040-X) for the year you underpaid, and you may owe a penalty for underpayment of estimated tax. Going forward, request withholding on Form W-4V to avoid the same problem next year.

Can I reduce my combined income by donating to charity?

Charitable donations lower your taxable income, but they do not lower your combined income for Social Security purposes. The IRS counts combined income before deductions, so charity does not help you stay below the threshold.

Does my spouse's Social Security count toward my combined income?

No. Each person's combined income is calculated separately. Your spouse's benefits do not count toward your threshold, and yours do not count toward theirs — even if you file jointly.

What if I receive both Social Security and SSI?

SSI (Supplemental Security Income) does not count as income for the Social Security tax calculation. Only your Social Security benefits count. However, if you receive both, you are likely below the income threshold anyway, since SSI is means-tested.
