You may not have to report SSDI income at all, depending on your total income

Whether you report SSDI on your federal tax return depends on how much money you earned that year from all sources combined. If your SSDI is your only income and you're single, you probably won't owe federal income tax and won't need to file a return. But if you have other income—wages, interest, pensions, or self-employment earnings—you may have to report your SSDI even though it's not technically taxable itself.

The IRS uses a formula called "combined income" to decide this. Combined income includes half of your SSDI benefits plus all your other income. If that total exceeds a certain threshold, you must file a return. The threshold depends on your filing status and whether you're married filing jointly. For 2024, a single person with no other income needs to file only if their combined income exceeds $25,000. A married couple filing jointly has a higher threshold.

The confusing part: even though SSDI itself is not taxable income, you still have to count it when you're doing this math. You're not paying tax on the SSDI, but you are reporting it to show the IRS your full financial picture.

Key Takeaways

  • If SSDI is your only income, you usually do not have to file a federal tax return at all.
  • If you have other income (wages, interest, pensions), you must file a return and report your SSDI amount, even though the SSDI itself is not taxed.
  • The IRS uses "combined income"—half your SSDI plus all other income—to determine whether you must file.
  • Filing thresholds vary by filing status; married couples filing jointly have a higher threshold than single filers.
  • You will receive a form SSA-1099 from Social Security showing your SSDI amount, which you use to complete your tax return.

How the IRS counts your SSDI when deciding if you must file

The IRS does not tax SSDI itself, but it does count half of your SSDI benefits when calculating your "combined income." This is the number that determines whether you cross the filing threshold. Combined income = (one-half of your SSDI) + all other income you received that year.

For example: if you received $12,000 in SSDI and earned $15,000 in wages, your combined income is $6,000 (half of $12,000) plus $15,000, which equals $21,000. For a single filer in 2024, the threshold is $25,000, so you would not be required to file based on this income alone. But if you also had $5,000 in interest income, your combined income would be $26,000, and you would cross the threshold.

The threshold amounts change each year and depend on whether you are single, married filing jointly, married filing separately, head of household, or may have access to widow or widower. The IRS publishes updated thresholds every January. You can find the current year's thresholds on the IRS website or ask a tax preparer.

When you must report SSDI even if you don't owe tax

Some people must file a return even though they will not owe any federal income tax. This happens when you have other income that requires you to file—such as self-employment income of $400 or more, or when you want to claim a refundable tax credit like the Earned Income Tax Credit (EITC).

If you fall into this situation, you will report your SSDI on your return using the form SSA-1099 that Social Security sends you. The SSDI amount goes on your return, but it does not increase the tax you owe. Instead, it is used to calculate whether any of your other income becomes taxable.

This matters most if you have both SSDI and wages. The presence of SSDI can push some of your other income into a taxable range, even though the SSDI itself is not taxed. A tax preparer can walk you through this calculation if you are unsure.

What form Social Security sends you and how to use it

Social Security mails you a form SSA-1099 (Social Security Benefit Statement) by January 31 each year if you received SSDI during that year. This form shows the total amount of SSDI you received. You do not send this form to the IRS; instead, you use the information on it to fill out your own tax return.

If you file electronically or use tax software, you will enter the SSDI amount from your SSA-1099 into the appropriate field. If you file on paper, you report it on your Form 1040 (U.S. Individual Income Tax Return). The exact line depends on your situation and whether any of your SSDI is taxable—which, as noted, is rare.

Keep your SSA-1099 with your tax records. If you lose it or did not receive one, you can request a replacement from Social Security by calling 1-800-772-1213 or visiting your local Social Security office.

State income tax and SSDI

Federal income tax rules do not explore to state income tax. Some states do not tax SSDI at all. Other states tax SSDI the same way the federal government does—meaning they count it in the combined income calculation but do not tax the SSDI itself. A few states have their own rules that differ from federal rules.

If you live in a state with income tax, check your state's tax agency website or ask a tax preparer whether you must report SSDI on your state return. The threshold for filing a state return may also be different from the federal threshold, so you could be required to file a state return even if you do not file federally.

States that do not tax income at all—such as Florida, Texas, and Wyoming—do not require you to report SSDI on a state return because there is no state income tax to file.

What happens if you don't file when you should have

If you were required to file a federal tax return but did not, the IRS may contact you. The consequences depend on whether you owed tax. If you did not owe tax, the IRS typically sends a notice asking you to file. If you file late but owed no tax, you usually face no penalty.

If you owed tax and did not file, penalties and interest accrue. The failure-to-file penalty is usually 5 percent of the unpaid tax for each month the return is late, up to 25 percent. Interest is charged on top of that. If you believe you should have filed but did not, you can file a late return at any time. The sooner you file, the sooner any penalties stop accumulating.

If you are unsure whether you were required to file in a past year, a tax preparer or the IRS can help you determine this. You can also call the IRS at 1-800-829-1040 to ask.

Frequently Asked Questions

Do I have to report SSDI if it's my only income?

No. If SSDI is your only income and you are single, you do not have to file a federal tax return. The threshold for single filers with only SSDI income is $25,000 in combined income for 2024. If you are married filing jointly with only SSDI, the threshold is higher. However, if you want to claim a refundable tax credit, you may want to file anyway.

Will I owe taxes on my SSDI?

Probably not. SSDI itself is not taxable income for most people. However, if you have other income and your combined income exceeds the threshold, up to 85 percent of your SSDI could become taxable. This is rare and usually only happens if you have substantial other income like wages or pensions.

What if I received SSDI for only part of the year?

Social Security will report the amount you received on your SSA-1099, even if it was only for part of the year. Use that amount when calculating your combined income. The filing threshold does not change based on how long you received benefits.

Can I file my taxes without the SSA-1099?

You should wait for your SSA-1099 before filing, since you need the exact amount Social Security reports. If you file before receiving it and the amount is different, you may need to file an amended return. If you did not receive your SSA-1099 by early February, contact Social Security to request a replacement.

Do I need to report SSDI on my state taxes?

It depends on your state. Some states do not tax SSDI at all. Others follow federal rules. A few have different rules. Check your state's tax agency website or ask a tax preparer about your state's specific requirements.
