Who Must File Taxes on SSDI Income

Whether you file taxes depends on your total income for the year, not on whether you receive SSDI alone. The Social Security Administration does not withhold federal income tax from SSDI payments automatically. You owe taxes only if your combined income — SSDI plus any other earnings or income — exceeds the threshold set by the IRS for your filing status.

For 2024, if SSDI is your only income, you generally do not have to file unless your total income exceeds $14,600 (if you are single) or $29,200 (if you are married filing jointly). These thresholds change each year. However, if you have other income — wages from work, interest, dividends, or self-employment income — you may owe taxes even if your SSDI alone is below the threshold.

The IRS counts SSDI differently than other income. Up to 85 percent of your SSDI benefits may be taxable if your "combined income" (adjusted gross income plus nontaxable interest plus half your SSDI) exceeds certain limits. For 2024, those limits are $25,000 for single filers and $32,000 for married couples filing jointly. If you are married filing separately, the limit is zero.

Key Takeaways

  • You must file taxes if your total income for the year exceeds $14,600 (single) or $29,200 (married filing jointly), even if SSDI is your only source of income.
  • SSDI itself is not automatically taxed, but it becomes taxable if your combined income exceeds $25,000 (single) or $32,000 (married filing jointly).
  • You may owe taxes on part of your SSDI even if you do not meet the filing threshold, so filing can sometimes reduce what you owe overall.
  • Social Security sends Form SSA-1099 by January 31 each year showing your SSDI income; use this to calculate whether you must file.

How to Calculate Your Combined Income

To know whether any of your SSDI is taxable, you need to calculate your "combined income" using the IRS formula. Combined income equals your adjusted gross income (all wages, interest, dividends, and other income) plus any nontaxable interest plus half of your SSDI benefits.

Example: You received $15,000 in SSDI and earned $8,000 from part-time work. Your adjusted gross income is $8,000. Half your SSDI is $7,500. Your combined income is $8,000 + $0 (no nontaxable interest) + $7,500 = $15,500. Since $15,500 exceeds $25,000 for single filers, you do not owe taxes on your SSDI in this case — but you may owe taxes on your wages. If you had earned $20,000 instead, your combined income would be $27,500, and up to 85 percent of your SSDI could become taxable.

The calculation is complex because the taxable portion of SSDI depends on how much other income you have. If your combined income is between $25,000 and $34,000 (single), up to 50 percent of your SSDI is taxable. If it exceeds $34,000, up to 85 percent is taxable. Married couples have different thresholds: $32,000 to $44,000 for the 50 percent tier, and above $44,000 for the 85 percent tier.

When You Should File Even If You Do Not Owe Taxes

You may want to file a tax return even if your income is below the filing threshold. Filing can sometimes reduce the taxes you owe or increase a refund you are may have access to to. This is especially true if you had taxes withheld from wages or if you are due the Earned Income Tax Credit (EITC).

If you worked part of the year and your employer withheld federal income tax from your paychecks, you may be owed a refund. The only way to get that refund is to file a return. Similarly, if you have a dependent child or grandchild and your income is low enough, you may be due the EITC, which can result in a refund of several thousand dollars even if you owe no income tax.

Another reason to file: if you have income that was not reported to the IRS (such as cash tips or self-employment income under $400), filing a return creates an official record and can protect you from IRS inquiries later. Many people on SSDI who work part-time find that filing saves them money overall.

What Documents You Need to File

Social Security mails Form SSA-1099 to you by January 31 each year. This form shows the total SSDI you received in the previous year. You will need this form to file your taxes, whether you file on paper or electronically.

If you had other income, you will also need the forms your employer or financial institution sent you: W-2 forms from employers, 1099 forms from banks or investment accounts, and 1099-NEC or 1099-MISC forms if you did freelance or self-employment work. Gather all these documents before you start your return.

If you are filing on your own using tax software, the software will walk you through entering your SSA-1099 information and calculating whether any of your SSDI is taxable. If you are using a tax preparer or the IRS Free File program, bring your SSA-1099 and all other income documents with you.

Filing Your Return: Paper, Software, or Free Help

You have three main options for filing: use tax software, file on paper, or use free tax preparation help. The IRS Free File program offers free tax software to people with income below a certain level (usually around $60,000 for 2024). You can find participating software providers at IRS.gov.

If you prefer to file on paper, you can read Form 1040 and the worksheets you need from IRS.gov, fill them out by hand, and mail them to the IRS address listed in the instructions. This takes longer to process but works if you have a straightforward return with only SSDI and perhaps one W-2.

Many communities offer free tax preparation through VITA (Volunteer Income Tax information) sites, often run by nonprofits or libraries. VITA preparers are trained to handle SSDI income and can file your return electronically, which is faster than mailing. Search for VITA sites near you at IRS.gov or call 211.

What Happens If You Do Not File When You Should

If your income exceeds the filing threshold and you do not file, the IRS may eventually contact you. However, because SSDI income is reported directly to the IRS by Social Security, the IRS usually knows your income already. If you owe taxes and do not file, penalties and interest will accumulate on what you owe.

More importantly, if you do not file and you are due a refund (for example, because taxes were withheld from wages), you lose that refund. The IRS holds unclaimed refunds for three years, but after that the money goes to the U.S. Treasury. Filing protects you from penalties and ensures you get any refund you are owed.

If you have not filed for previous years and think you may owe taxes, you can file back returns. The IRS generally does not pursue penalties for unfiled returns if you are owed a refund, so filing old returns is usually in your favor. A tax preparer or VITA site can help you file prior-year returns.

SSDI and State Income Taxes

Federal tax rules and state tax rules are different. Some states do not tax SSDI at all, while others tax it the same way the federal government does. A few states have their own thresholds and rules.

If you live in a state with an income tax, check your state's tax website or call your state tax agency to learn whether SSDI is taxable in your state. States that do not tax SSDI include California, Illinois, Louisiana, Mississippi, New York, and others — the list changes, so verify your state's current rules. Even if your state does not tax SSDI, you may still owe state taxes on other income like wages.

Frequently Asked Questions

Will receiving SSDI affect my taxes if I have no other income?

No. If SSDI is your only income and it is below $14,600 (single) or $29,200 (married filing jointly), you do not have to file federal taxes. However, if you had taxes withheld from wages earlier in the year, filing may get you a refund.

Do I have to pay taxes on all of my SSDI or just part of it?

Only part of it, if any. Up to 85 percent of your SSDI may be taxable depending on your combined income. If your combined income is below $25,000 (single) or $32,000 (married), none of your SSDI is taxable. The exact amount depends on your other income.

What if I worked and received SSDI in the same year?

You must count both your wages and your SSDI when calculating whether you owe taxes. Your wages are always taxable. Your SSDI becomes taxable only if your combined income exceeds the thresholds. You may owe taxes on your wages even if your SSDI is not taxable.

Can I file my taxes online if I receive SSDI?

Yes. Tax software and the IRS Free File program both handle SSDI income. When you enter your SSA-1099 information, the software calculates whether any of your SSDI is taxable and prepares your return. Electronic filing is faster than mailing a paper return.

What if I lost my SSA-1099 form?

You can request a replacement from Social Security by calling 1-800-772-1213 or visiting your local Social Security office. You can also create a my Social Security account at ssa.gov and view your SSA-1099 online. The IRS also has a record of your SSDI income, so you can file without the physical form if necessary.
