Social Security payments are subject to federal income tax, but only if your total income exceeds certain thresholds

Whether you owe taxes on Social Security depends on your combined income—not just what you receive from Social Security. The IRS counts half of your Social Security benefits plus all your other income (wages, pensions, interest, dividends) to determine if you cross the taxable threshold. Most people do not pay taxes on Social Security, but those with substantial other income often do.

The thresholds are the same regardless of age. If you are single and your combined income exceeds $25,000, you may owe taxes on up to 50 percent of your benefits. If you are married filing jointly, the threshold is $32,000. Above $34,000 (single) or $44,000 (married filing jointly), you may owe taxes on up to 85 percent of your benefits. These thresholds have not changed since 1984.

Key Takeaways

  • Social Security is taxable only if your combined income—half your benefits plus all other income—exceeds $25,000 (single) or $32,000 (married filing jointly).
  • The IRS taxes up to 50 percent of your benefits if you are slightly over the threshold, and up to 85 percent if you are well over it.
  • You can request voluntary withholding directly from your Social Security check to avoid a tax bill at filing time.
  • State taxes on Social Security vary by state; 13 states tax Social Security income under certain conditions, while 37 states do not tax it at all.

How the IRS calculates whether you owe taxes

The calculation starts with your combined income, which the Social Security Administration defines as adjusted gross income plus nontaxable interest plus half of your Social Security benefits. This is the number that determines whether you cross into taxable territory.

If you are single and your combined income is between $25,000 and $34,000, you may owe federal income tax on up to 50 percent of your benefits. If your combined income exceeds $34,000, you may owe tax on up to 85 percent of your benefits. For married couples filing jointly, the first threshold is $32,000 and the second is $44,000.

The actual amount you owe depends on your tax bracket and how much of your benefits fall into the taxable range. A tax professional or the IRS worksheet in Publication 915 can calculate the exact amount. Many people find it simpler to request withholding directly from their check rather than face a surprise bill in April.

Requesting voluntary withholding from your Social Security check

You can ask the Social Security Administration to withhold federal income tax from your monthly benefit payment. This prevents you from owing a large amount when you file your return. You do this by completing Form W-4V and submitting it to your local Social Security office or mailing it to the address on the form.

On Form W-4V, you choose a withholding rate: 7 percent, 10 percent, 12 percent, or 22 percent of your benefit. You can change or stop withholding at any time by submitting a new form. If you want to withhold a specific dollar amount instead of a percentage, you can request that as well, though the form itself only offers percentage options—call Social Security to arrange a custom amount.

Withholding does not reduce the amount of your benefit; it straightforward sets aside part of each payment for taxes. If you withhold too much, you will receive a refund when you file. If you withhold too little, you will owe at tax time, but you will have paid some of the bill throughout the year.

State taxes on Social Security income

Thirteen states tax Social Security benefits under certain conditions: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The rules vary significantly by state. Some states exempt benefits entirely for people over a certain age. Others tax benefits the same way the federal government does—only if your income exceeds a threshold.

Colorado, Kansas, Missouri, and Nebraska have phased out their taxes on Social Security over time, so fewer residents pay state tax on benefits each year. Connecticut and Vermont tax benefits but offer substantial exemptions based on age or income. Montana and New Mexico tax benefits but allow a deduction. Check your state's tax authority website or a tax professional to understand your specific state's rules.

The remaining 37 states do not tax Social Security benefits at all, regardless of your income level. If you live in one of those states, you only owe federal tax on your benefits if you meet the federal thresholds described above.

What happens if you do not withhold and owe taxes

If you do not request withholding and your combined income exceeds the threshold, you will owe federal income tax on your Social Security when you file your return. You can pay the full amount due, or you can set up a payment plan with the IRS if you cannot pay in full.

Owing taxes on Social Security does not trigger any penalty or loss of benefits. The IRS straightforward treats it like any other income tax debt. If you owe a large amount and expect this pattern to continue, requesting withholding on Form W-4V is usually simpler than managing a payment plan each year.

How to report Social Security on your tax return

The Social Security Administration sends you a Form SSA-1099 by January 31 each year showing the total benefits you received. You use this form to report your benefits on your federal tax return. If you are filing Form 1040, you report your Social Security on lines 5a and 5b, which ask for the total benefits received and the taxable amount.

If you use tax software, it will walk you through entering the information from your SSA-1099. If you file by hand or with a tax professional, they will use the IRS worksheet in Publication 915 to calculate how much of your benefits are taxable based on your combined income. You then report the taxable amount on your return.

Frequently Asked Questions

Can I avoid paying taxes on Social Security by not reporting it?

No. The Social Security Administration reports all benefits to the IRS, so the IRS knows what you received regardless of whether you report it. Failing to report Social Security income is tax evasion and can result in penalties, interest, and criminal charges.

Does working while receiving Social Security change the tax rules?

Working does not change whether your benefits are taxable, but it does increase your combined income, which may push you over the threshold. Wages count toward your combined income just like any other income. If you are under full retirement age and earn above a certain amount, Social Security will also reduce your monthly benefit, though that is a separate rule from taxation.

What if I receive both Social Security and a pension?

Both count toward your combined income. A pension is treated as regular income, and half your Social Security is added to it. If the total exceeds the threshold for your filing status, you will owe taxes on part of your benefits. This is common for people who worked in government jobs that did not pay into Social Security.

Do I have to pay taxes on Social Security if I am over 65?

Age does not matter. The tax rules are the same whether you are 65 or 85. What matters is your combined income. Some states offer age-based exemptions, but the federal government does not.

If I request withholding, will I definitely not owe taxes?

Not necessarily. Withholding is based on the percentage you choose, and it may not cover your full tax liability if you have other income or if your tax situation is complex. However, withholding reduces the risk of owing a large amount at tax time. A tax professional can help you choose a withholding rate that matches your expected tax bill.
