Whether You Need to File Depends on Your Total Income

You may have to file a federal tax return even though you receive Social Security Disability Insurance (SSDI), because SSDI counts as income for tax purposes. The IRS does not care that the money comes from a government program — what matters is whether your total income (SSDI plus any other earnings or unearned income) crosses the threshold where filing becomes required.

The threshold changes each year and depends on your filing status and age. For 2024, a single person under 65 must file if their gross income is $14,600 or more. If you are 65 or older, the threshold is $18,350. These numbers include your SSDI benefits plus wages, interest, dividends, rental income, or any other money you received. If you are married filing jointly, the thresholds are higher.

Even if your income is below the filing threshold, you may still want to file — particularly if you had taxes withheld from other income sources or if you are may have access to to refundable tax credits like the Earned Income Tax Credit (EITC). Filing can get that money back to you.

Key Takeaways

  • SSDI counts as income for tax purposes, so you must add it to any wages, interest, or other money you received when calculating whether you owe a return.
  • For 2024, a single person under 65 must file if gross income reaches $14,600; the threshold is higher if you are 65 or older or married.
  • The IRS does not automatically withhold taxes from SSDI payments, so you may owe taxes at filing time even if no money was taken from your checks.
  • You can request voluntary withholding on your SSDI payments through Social Security if you want to reduce what you owe at tax time.
  • If you had taxes withheld from other income or earned less than the threshold, filing may still return money to you through refundable credits.

How SSDI Income Is Counted on Your Tax Return

The IRS counts SSDI as unearned income, meaning it is not wages from a job. You report it on your federal tax return using Form 1040, and it goes into the calculation of your total income. The amount you report is the total SSDI you received during the tax year — Social Security sends you a statement (Form SSA-1099) each January showing exactly what you received in the previous year.

However, not all of your SSDI is necessarily taxable. The IRS has a formula that determines what portion of your benefits count as taxable income. The formula depends on your combined income, which is your adjusted gross income plus nontaxable interest plus half of your SSDI benefits. If your combined income is below a certain threshold (between $25,000 and $34,000 for single filers in 2024, depending on other factors), none of your SSDI is taxable. If your combined income is above that range, up to 85 percent of your SSDI may be taxable.

This means that even if you have no other income, you may not owe tax on your SSDI. But if you have wages, interest, or other unearned income, that money can push you into a range where some of your SSDI becomes taxable. A tax professional or the IRS Free File program can walk you through this calculation.

When You Have Work Income in Addition to SSDI

If you work while receiving SSDI, your situation becomes more complex for taxes. You must report both your wages and your SSDI on your return. Your wages are earned income and are always taxable. Your SSDI becomes taxable based on the combined income formula described above — and your wages count toward that combined income, which can push more of your SSDI into the taxable range.

Additionally, if your work income is high enough, you may trigger the SSDI earnings test, which is a separate rule that reduces or suspends your SSDI payments themselves (not just the tax on them). In 2024, if you earn more than $1,550 per month, Social Security will reduce your benefit. This is a program rule, not a tax rule, but it affects how much SSDI you actually receive during the year — and therefore how much you report on your tax return.

Keep records of all wages you earned, including pay stubs and any 1099 forms from self-employment or contract work. These documents, along with your Form SSA-1099 from Social Security, are what you need to file an accurate return.

The IRS Free File Program and Tax Software Options

If your income is below a certain threshold (roughly $79,000 in 2024, though this changes yearly), you may be able to use the IRS Free File program at no cost. Free File includes tax software that walks you through reporting SSDI income and calculating how much of it is taxable. You can access Free File through the official IRS website — do not use third-party sites that claim to offer "free" filing but actually charge you.

If your income is above the Free File threshold, you can purchase tax software (TurboTax, H&R Block, TaxAct, and others) or work with a tax preparer. Many tax preparers offer reduced rates for people with low incomes. The National Association of Free and Charitable Tax Programs (NFCTP) maintains a directory of free tax help sites in your area — search "VITA" (Volunteer Income Tax information) plus your city or county name to find one near you.

Whichever route you choose, make sure the software or preparer knows you receive SSDI. The taxable portion of SSDI is not always obvious, and mistakes here are common. Having someone familiar with disability income can prevent errors that trigger an audit or delay your refund.

Voluntary Withholding to Reduce Your Tax Bill

Unlike wages, the IRS does not automatically withhold taxes from SSDI payments. This means that even if you owe taxes, no money is taken from your monthly check. You can request voluntary withholding if you want Social Security to hold back a portion of your benefit each month and send it to the IRS on your behalf.

To set up voluntary withholding, you complete Form W-4V (Voluntary Withholding Request) and submit it to Social Security. You choose a withholding rate — typically 7, 10, 15, or 25 percent of your monthly benefit. Social Security then reduces your monthly payment by that amount and forwards the withheld money to the IRS.

This does not change how much you owe in taxes — it just spreads the payment across the year instead of requiring a lump sum at tax time. If you know you will owe taxes and want to avoid a large bill in April, voluntary withholding can help. You can change or cancel your withholding request at any time by submitting a new Form W-4V or by calling Social Security at 1-800-772-1213.

What Happens If You Do Not File When Required

If your income exceeds the filing threshold and you do not file a return, the IRS may send you a notice. The consequences depend on whether you owe taxes. If you owe and do not pay, you will face penalties and interest charges that grow over time. If you are due a refund and do not file, you straightforward do not receive the refund — but you have three years to claim it before the IRS keeps the money.

If you receive a notice from the IRS, do not ignore it. Open it when ready and read what it says. If you believe you did not need to file, you can respond with documentation of your income. If you did owe and did not file, filing late is still better than not filing at all — the penalties for late filing are smaller than the penalties for not filing at all.

If you are unsure whether you need to file or if you have received a notice, contact a VITA site or a tax professional. Many offer free consultations to answer basic questions.

Frequently Asked Questions

Does Social Security send me a form showing how much SSDI I received?

Yes. Social Security mails Form SSA-1099 to you each January. It shows the total SSDI you received in the previous calendar year. Keep this form — you need it to file your tax return. If you do not receive it by early February, call Social Security at 1-800-772-1213 and request a replacement.

Can I claim SSDI as a dependent on someone else's tax return?

No. SSDI is your own income, and you cannot be claimed as a dependent based on receiving it. However, if someone else pays for more than half your living expenses and meets other IRS tests, they may be able to claim you as a dependent — but that is a separate question from your SSDI income.

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

Report only the SSDI you actually received. Your Form SSA-1099 will show the correct amount. If you started or stopped receiving benefits partway through the year, the form reflects that. Use the amount on the form when you file your return.

Do I have to pay state income tax on SSDI?

It depends on your state. Most states do not tax SSDI, but a few do. Check your state's tax agency website or ask a tax preparer whether your state taxes Social Security benefits. If it does, you may need to file a state return even if you do not owe federal tax.

What if I cannot afford to pay the taxes I owe?

Contact the IRS or work with a tax professional to explore payment plans. The IRS offers installment agreements that let you pay over time, and you may may have access to for an offer in compromise (a settlement for less than you owe) if your income is very low. Do not ignore the bill — penalties and interest grow quickly.
