The basic rule: most SSDI recipients pay no federal income tax on their benefits

If SSDI is your only income, you almost certainly will not owe federal income tax on it. The Social Security Administration does not withhold taxes from SSDI payments, and most people who receive only SSDI have income too low to trigger a tax filing requirement.

The situation changes if you have other income—wages from work, interest, pensions, or self-employment earnings. In that case, part of your SSDI may become taxable. The amount depends on your "combined income," which is a specific calculation Social Security uses.

State income tax is separate. A handful of states tax SSDI; most do not. If you live in Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, or Vermont, you may owe state tax on SSDI even if you owe nothing to the federal government.

Key Takeaways

  • SSDI by itself is not taxable at the federal level, and the Social Security Administration does not withhold taxes from your payments.
  • If you have other income, part of your SSDI becomes taxable based on a formula using your "combined income"—not just your total earnings.
  • You calculate combined income by adding your SSDI to half your SSDI, plus all other income; the IRS uses this number to determine what portion of benefits is taxable.
  • Ten states tax SSDI benefits, so check your state's rules even if you owe nothing federally.
  • If you work and earn wages, you may owe taxes on both the wages and a portion of your SSDI, and you should file a tax return to report both.

How combined income determines whether your SSDI is taxable

The IRS uses a two-tier system. Your "combined income" is calculated as: your adjusted gross income (or modified adjusted gross income) plus nontaxable interest plus half of your SSDI benefits. That total determines whether any of your SSDI becomes taxable.

If your combined income is below $25,000 (or $32,000 if you are married filing jointly), none of your SSDI is taxable. If it is between $25,000 and $34,000 (or $32,000 and $44,000 for married filing jointly), up to 50 percent of your SSDI may be taxable. If it exceeds $34,000 (or $44,000 for married filing jointly), up to 85 percent of your SSDI may be taxable.

These thresholds have not changed since 1984, so they affect more people now than they did when they were set. If you have modest wages or a small pension in addition to SSDI, you may cross into the taxable range even though your total income feels low.

What counts as income for this calculation

Income includes wages, self-employment earnings, pensions, annuities, capital gains, dividends, interest, and rental income. It also includes income from other Social Security benefits—Supplemental Security Income (SSI) does not count, but Retirement or Survivor benefits do.

Some income does not count. Tax-exempt interest (such as interest from municipal bonds) does count for the combined income calculation, even though it is not taxable. Gifts and inheritances do not count. Neither does money from a reverse mortgage (though interest on it does).

If you are married and file jointly, the IRS combines both spouses' income for this calculation, even if only one of you receives SSDI. If you are married and file separately, the rules are harsher—the threshold drops to zero, meaning virtually all your SSDI becomes taxable.

Working while on SSDI and managing your tax bill

If you work and earn wages, you will likely owe federal income tax on those wages. You may also owe tax on a portion of your SSDI if your combined income crosses the threshold. This means your tax bill can be higher than you expect, because the SSDI portion is added on top of the tax you already owe on wages.

The Social Security Administration does not withhold taxes from SSDI payments automatically. If you think you will owe tax, you can request voluntary withholding by completing Form W-4V and sending it to your local Social Security office. This lets you have a small amount withheld from each SSDI payment, which reduces what you owe when you file your return.

Alternatively, you can make quarterly estimated tax payments to the IRS if you prefer to pay in advance rather than withhold from SSDI. Many people find withholding simpler because it happens automatically.

Filing a tax return when you receive SSDI

You are required to file a federal tax return if your gross income exceeds the standard deduction for your age and filing status. For 2024, the standard deduction is $14,600 for a single person under 65, and $17,550 if you are 65 or older. If your SSDI plus other income exceeds these amounts, you must file.

Even if you are not required to file, you may want to. If taxes were withheld from your SSDI or if you made estimated payments, filing a return is how you claim a refund. You will need your Social Security Statement (Form SSA-1099), which the Social Security Administration mails in January each year, to report your SSDI on your return.

If you have questions about whether you must file or how to report SSDI on your return, the IRS offers free tax help through VITA (Volunteer Income Tax information) sites, which serve people with low to moderate income. You can find a VITA site near you at irs.gov.

State income tax on SSDI

Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, and Vermont all tax SSDI benefits to some degree. The rules vary by state—some tax it the same way the federal government does (using combined income thresholds), while others have their own formulas.

If you live in one of these states and have other income, contact your state tax authority or a tax preparer familiar with your state's rules. Some states offer exemptions or deductions that reduce the amount of SSDI subject to tax, so it is worth checking before you assume you owe.

If you moved to a new state during the tax year, you may owe tax to both your old state and your new state, depending on when you moved and each state's rules. This is another situation where a tax preparer can save you time and money.

What to do if you cannot pay taxes you owe

If you file a return and owe tax but cannot pay the full amount, the IRS offers payment plans. You can request a short-term extension (up to 180 days) at no cost, or set up a monthly installment agreement. The IRS also has hardship provisions if paying would prevent you from meeting basic living expenses.

Do not ignore a tax bill. The IRS can offset your SSDI payments to collect unpaid taxes, meaning money is withheld from your benefits. If you receive a notice of intent to offset, you have the right to request a hearing and explain your situation. Responding quickly gives you the best chance of working out an alternative arrangement.

If you need help, the IRS Low Income Taxpayer Clinic program offers free representation to people with limited income. You can find a clinic near you at taxpayeradvocate.irs.gov.

Frequently Asked Questions

Do I have to file a tax return if I only receive SSDI?

Only if your total income (SSDI plus any other income) exceeds the standard deduction for your age and filing status. For 2024, that is $14,600 for a single person under 65. If SSDI is your only income and it is below that amount, you do not have to file. However, if taxes were withheld from your SSDI, filing lets you claim a refund.

Can the IRS take my SSDI to pay back taxes?

Yes. The IRS can offset SSDI payments to collect unpaid federal taxes. If you receive a notice of intent to offset, you have the right to request a hearing. Contact the IRS or a Low Income Taxpayer Clinic when ready to discuss your options, including payment plans or hardship relief.

What if I work part-time and receive SSDI—do I owe tax on both?

You owe tax on your wages. You may also owe tax on part of your SSDI if your combined income (wages plus half your SSDI, plus other income) exceeds the threshold of $25,000 for single filers. Request voluntary withholding on Form W-4V to avoid a large bill at tax time.

Does my spouse's income affect whether my SSDI is taxable?

Only if you file a joint return. If you are married and file jointly, the IRS combines both spouses' income for the combined income calculation. If you file separately, the threshold drops to zero, making almost all your SSDI taxable. Filing jointly is usually better.

Where do I report my SSDI on my tax return?

You report SSDI on Form 1040, lines 5a and 5b. The Social Security Administration sends you Form SSA-1099 in January showing how much you received. If part of your SSDI is taxable, you will include that amount on line 5b of your return.
