You must report SSDI on your tax return only if your combined income exceeds a threshold set by the IRS—and for most SSDI recipients, it does not.

The IRS requires you to report SSDI benefits as income only when your combined income crosses a specific line. Combined income means your SSDI plus any other income you receive: wages, interest, dividends, self-employment earnings, or taxable pensions. For most people receiving SSDI alone, combined income stays below the threshold, so no tax return is required and no SSDI needs to be reported.

The threshold depends on your filing status. For a single filer in 2024, combined income must exceed $25,000 before any SSDI becomes taxable. For married filing jointly, the threshold is $32,000. If you fall below these numbers, you do not report SSDI on your return—even if you file for other reasons, such as claiming the Earned Income Tax Credit.

If your combined income does exceed the threshold, you do not report all of your SSDI. Instead, the IRS uses a formula to calculate how much of your benefit counts as taxable income. Up to 85 percent of your SSDI can become taxable, but only the amount above the threshold is subject to tax. This means even high-income SSDI recipients rarely pay tax on the full benefit amount.

Key Takeaways

  • You report SSDI on your tax return only if your combined income (SSDI plus all other income) exceeds $25,000 for single filers or $32,000 for married filing jointly.
  • Combined income includes wages, self-employment earnings, interest, dividends, pensions, and any other taxable income, not just SSDI.
  • If you exceed the threshold, use IRS Worksheet 1 (or Worksheet 2 if you received nontaxable interest) to calculate how much SSDI is taxable—you do not report the entire benefit.
  • Social Security sends Form SSA-1099 by January 31 each year showing your total SSDI for the prior year; use this figure on your return.
  • If you owe tax on SSDI, you can request voluntary withholding from your benefit or make quarterly estimated tax payments to avoid a penalty.

How the IRS Calculates Taxable SSDI

The calculation is not straightforward, but the IRS provides worksheets to walk you through it. You start by adding your SSDI to your other income sources. Then you subtract the threshold for your filing status. That difference is your "excess combined income." The IRS then applies a two-tier formula: 50 percent of your excess combined income becomes potentially taxable, up to a limit. If your excess combined income is very high, an additional 35 percent of SSDI above that limit can also become taxable, up to a maximum of 85 percent of your total benefit.

The worksheets—IRS Worksheet 1 (for most people) and Worksheet 2 (if you received nontaxable interest or foreign earned income)—are published in the instructions to Form 1040 each year. You do not need to submit the worksheet with your return, but you should keep it for your records. If you work with a tax preparer or use tax software, the program usually calculates this automatically once you enter your SSDI amount from Form SSA-1099.

Example: You are single and received $15,000 in SSDI and $12,000 in part-time wages. Your combined income is $27,000. The threshold for single filers is $25,000, so your excess is $2,000. Using the formula, 50 percent of that excess ($1,000) becomes taxable SSDI. You would report $1,000 as taxable income on your return, not the full $15,000 benefit.

What Form SSA-1099 Shows and How to Use It

Social Security mails Form SSA-1099 to you by January 31 each year. This form shows the total SSDI you received in the prior calendar year in Box 5. This is the figure you use to calculate combined income and determine whether you must file a return. The form also shows any federal income tax already withheld from your benefit in Box 6, if you requested voluntary withholding.

Keep your SSA-1099 with your tax records even if you do not file a return. If you do file, enter the amount from Box 5 on your return as instructed by the IRS form you are using. If you received SSDI for only part of the year—for example, you started receiving it in June—the SSA-1099 will show only the months you were paid.

If you do not receive an SSA-1099 by early February, contact Social Security at 1-800-772-1213 or visit your local Social Security office. You can also create a my Social Security account online to view your benefit statements and tax documents.

When You Must File Even If SSDI Is Not Taxable

You may be required to file a tax return even if your SSDI is below the taxable threshold. This happens if you have other income that triggers a filing requirement. For example, if you earned $400 or more in self-employment income, you must file to pay self-employment tax. If you earned wages and your employer did not withhold enough tax, filing allows you to claim a refund of overpaid tax.

You might also file voluntarily to claim tax credits that reduce your tax or produce a refund. The Earned Income Tax Credit (EITC) and the Additional Child Tax Credit are common reasons. These credits can result in a refund even if you owe no tax, but you must file to claim them. If you are unsure whether you must file, use the IRS Interactive Tax Assistant on IRS.gov or contact a tax professional.

Voluntary Withholding and Estimated Tax Payments

If you know your SSDI will be taxable and you do not want to owe a large amount when you file, you can request that Social Security withhold federal income tax from your benefit each month. You do this by completing Form W-4V (Voluntary Withholding Request) and submitting it to Social Security. You choose the withholding rate: 7, 10, 15, or 25 percent of your benefit. Social Security will then reduce your monthly payment by that amount and send the withheld tax to the IRS on your behalf.

Alternatively, if you have other income (such as wages or self-employment earnings), you can adjust your withholding on that income to cover the tax on your SSDI. This is often simpler if you work. If you have substantial SSDI income and little other income, you can also make quarterly estimated tax payments directly to the IRS using Form 1040-ES. Estimated payments are due April 15, June 15, September 15, and January 15.

Requesting withholding or making estimated payments does not change whether you must file a return—it only reduces the amount you owe or owed when you do file. It also helps you avoid penalties for underpayment of tax during the year.

State Income Tax and SSDI

Most states do not tax SSDI benefits, but a few do. As of 2024, Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont tax some or all SSDI income under certain conditions. The rules vary by state: some tax SSDI only if your total income exceeds a state-specific threshold, others tax it only for higher-income recipients, and some exempt it entirely for residents over a certain age.

If you live in one of these states, contact your state tax authority or a tax preparer familiar with your state's rules. You may need to file a state return even if you do not file a federal return, or you may may have access to for a state exemption. State tax forms and instructions are usually available on your state's department of revenue website.

What Happens If You Do Not Report Taxable SSDI

If your combined income exceeds the threshold and you do not report the taxable portion of your SSDI on your return, the IRS may contact you. Social Security reports all SSDI payments to the IRS, so the IRS knows how much you received. If you file a return showing income below the threshold, the IRS will notice the discrepancy and may send you a notice asking you to file an amended return or pay additional tax plus interest and penalties.

The penalty for failing to report income is typically 20 percent of the underpaid tax, plus interest calculated from the original due date. If the failure is deemed fraudulent (intentional), the penalty can be as high as 75 percent. Filing an amended return (Form 1040-X) as soon as you realize the error reduces penalties and shows good faith to the IRS.

Frequently Asked Questions

Do I have to report SSDI if I live on very little and have no other income?

No. If SSDI is your only income and it is below $25,000 (single) or $32,000 (married filing jointly), your combined income does not exceed the threshold, so you do not report any SSDI on your return. You do not need to file a federal tax return unless another requirement applies, such as self-employment income or a tax credit you want to claim.

What if I work part-time and receive SSDI—do I have to report both?

Yes, both count toward combined income. Your wages plus your SSDI determine whether you cross the threshold. If the total exceeds $25,000 (or $32,000 if married filing jointly), you must file a return and report the taxable portion of your SSDI using the IRS worksheet. The good news: your wages may also may have access to you for the Earned Income Tax Credit, which can reduce or eliminate your tax.

Can I reduce my taxable SSDI by reducing my other income?

Not directly, but you can reduce your combined income by maximizing tax-deductible expenses if you are self-employed. For example, if you have self-employment income, deducting business expenses lowers your net self-employment income, which lowers combined income and may reduce taxable SSDI. Work with a tax preparer to identify deductions you may have missed.

If I request withholding on my SSDI, do I still have to file a tax return?

Withholding does not change your filing requirement. If your combined income exceeds the threshold, you must file a return to report the taxable SSDI, even if you requested withholding. Withholding straightforward reduces the amount you owe when you file. If withholding covers all your tax liability, you may get a refund when you file.

What if I made a mistake on last year's return and did not report taxable SSDI?

File Form 1040-X (Amended U.S. Individual Income Tax Return) for that year as soon as possible. Include the corrected SSDI income and recalculate your tax. The IRS will assess interest on any unpaid tax from the original due date, but filing an amended return promptly shows good faith and may reduce penalties. You can file an amended return up to three years after the original due date.
