Whether you file taxes on SSDI depends on your total income, not just your benefits

You do not automatically have to file a tax return just because you receive SSDI. The Social Security Administration does not withhold federal income tax from SSDI payments. However, you may owe taxes if your total income — including SSDI, wages, interest, or other sources — crosses certain thresholds. The IRS sets these thresholds differently depending on whether you are single, married, or head of household.

The key number is your combined income. This is not the same as your total income. Combined income includes half of your SSDI benefits plus all your other income sources. If your combined income exceeds a certain amount, part of your SSDI becomes taxable. For 2024, if you are single and your combined income is between $25,000 and $34,000, you may owe tax on up to 50 percent of your benefits. If it exceeds $34,000, you may owe tax on up to 85 percent of your benefits. These thresholds change slightly each year.

The safest approach is to calculate your combined income and compare it to the current year's thresholds. If you are unsure whether you cross the line, filing a return costs nothing and protects you from penalties. The IRS publishes a worksheet each year to help you determine whether you owe tax on SSDI.

Key Takeaways

  • SSDI is not automatically taxable, but it becomes taxable if your combined income (half your SSDI plus all other income) exceeds $25,000 for single filers or $32,000 for married couples filing jointly.
  • The Social Security Administration sends you a Form SSA-1099 each January showing how much SSDI you received in the previous year, which you need to calculate combined income.
  • If you have little or no income besides SSDI, you likely do not owe federal income tax, but you should verify using the IRS worksheet.
  • Some states tax SSDI and some do not, so check your state's rules separately from federal rules.

How to calculate whether your SSDI is taxable

Start by gathering your income documents. You will need your Form SSA-1099 (sent by Social Security in January), any W-2 forms from work, and statements showing interest, dividends, or other income. Add up all income except SSDI. Then add half of your SSDI amount to that total. This sum is your combined income.

Once you have your combined income, compare it to the thresholds for your filing status. For single filers in 2024, the first threshold is $25,000. If your combined income is $25,000 or less, none of your SSDI is taxable. If it is between $25,000 and $34,000, up to 50 percent of your benefits may be taxable. If it exceeds $34,000, up to 85 percent may be taxable. Married couples filing jointly use thresholds of $32,000 and $44,000.

The IRS provides a detailed worksheet in Publication 915 to calculate the exact amount of SSDI that becomes taxable. This worksheet accounts for the phase-in of taxation and ensures you do not pay tax on more than 85 percent of your benefits. If the math feels complicated, a tax preparer or the IRS Volunteer Income Tax information (VITA) program can help you work through it for free.

When you must file a return even if you owe no tax

You must file a federal income tax return if your gross income exceeds the standard deduction for your age and filing status. In 2024, the standard deduction for a single person under 65 is $14,600. If you are 65 or older, it is $18,150. These amounts increase slightly each year.

Even if your income is below the standard deduction, filing a return may benefit you. If you paid taxes through withholding on wages or had taxes withheld from other income, filing allows you to claim a refund. You may also be may have access to to the Earned Income Tax Credit or other credits that require a return to claim.

If you are unsure whether your income exceeds the standard deduction, add up all your income sources (including half your SSDI) and compare it to the threshold for your age and status. If you are close to the line, filing is the safer choice.

What form Social Security sends you and how to use it

Each January, the Social Security Administration mails you a Form SSA-1099 showing the total SSDI you received in the previous calendar year. This form lists the amount in Box 5. You use this amount to calculate your combined income and to report SSDI on your tax return if any of it is taxable.

Keep your SSA-1099 with your tax records. If you file electronically, you will enter the SSDI amount from Box 5 into the appropriate line on your return. If you file by mail, you do not send the SSA-1099 to the IRS, but you must keep it for your records in case the IRS asks questions later.

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 will need the form to file accurately, and Social Security can issue a replacement copy.

State income tax rules for SSDI

Thirteen states tax SSDI: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The other 37 states and Washington, D.C., do not tax SSDI at all. If you live in a state that taxes SSDI, you must follow that state's rules in addition to federal rules.

State thresholds and tax rates vary widely. Some states use the same combined income thresholds as the federal government; others use different amounts. Some states exempt SSDI entirely for people over a certain age or with income below a certain level. You need to check your state's tax agency website or call them directly to understand your state's specific rules.

If you live in one of the 37 states that do not tax SSDI, you do not file a state return on SSDI income alone. However, if you have wages or other income, you may still owe state tax on that income.

What happens if you do not file when you should

If you owe federal income tax and do not file a return, the IRS will charge penalties and interest on the unpaid tax. The failure-to-file penalty is 5 percent of unpaid tax for each month the return is late, up to 25 percent. Interest accrues daily at a rate set quarterly by the IRS.

If you file late but owe no tax, you face no penalty. However, if you are may have access to to a refund and do not file, you have only three years to claim it before the money is forfeited to the U.S. Treasury. Many people who receive SSDI and have little other income are may have access to to refunds because of tax credits, so filing is worth doing even if you think you owe nothing.

If you realize you should have filed in a previous year, file that return as soon as possible. The IRS is often willing to reduce penalties if you file late returns voluntarily, especially if you owe little or nothing.

Free tax preparation resources for SSDI recipients

The IRS Volunteer Income Tax information (VITA) program offers free tax preparation to people with income below a certain threshold (usually around $60,000 for SSDI recipients). VITA sites are located in libraries, community centers, and nonprofit organizations across the country. You can find a site near you at IRS.gov or by calling 211.

The Tax Counseling for the Elderly (TCE) program provides free tax help to people 60 and older, regardless of income. If you may have access to, TCE can walk you through calculating combined income, determining whether SSDI is taxable, and filing your return.

Many nonprofit organizations that serve people with disabilities also offer free tax help or can refer you to someone who does. If you work with a benefits counselor or case manager, ask whether they know of local resources.

Frequently Asked Questions

Can I file taxes on SSDI if I have no other income?

If SSDI is your only income, you likely do not owe federal income tax because your combined income will be below the threshold. However, you should still calculate it to be certain. Use the IRS worksheet in Publication 915 or contact VITA for free help.

Do I have to report SSDI on my tax return if none of it is taxable?

No. If your combined income is below the first threshold ($25,000 for single filers in 2024), you do not report SSDI on your return at all. You only report it if part of it becomes taxable.

What if I earned wages and received SSDI in the same year?

Add your wages to half your SSDI to calculate combined income. If the total exceeds the threshold for your filing status, part of your SSDI becomes taxable. You will report both the wages and the taxable SSDI on your return.

Does filing taxes affect my SSDI benefits?

Filing a tax return does not change your SSDI payment amount. SSDI is not means-tested, so your income does not affect how much you receive. However, if you work and earn above the substantial gainful activity limit, that can affect your benefits — this is separate from taxes.

What if I cannot find my SSA-1099?

Contact Social Security at 1-800-772-1213 and request a replacement. You can also create a my Social Security account online at ssa.gov to view and print your SSA-1099 anytime after January.
