You may have to file taxes on SSDI income, depending on your total income and filing status

Social Security Disability Insurance (SSDI) payments themselves are not taxable income at the federal level in most cases. However, if you have other income — wages from work, interest, pensions, or self-employment — you may be required to file a tax return. The IRS uses a formula to determine whether part of your SSDI becomes taxable when combined with other income sources.

The key threshold is your "combined income," which the IRS calculates as your adjusted gross income plus nontaxable interest plus half of your SSDI benefits. If this number exceeds a certain amount based on your filing status, you owe federal income tax on a portion of your SSDI. Even if you do not owe tax, filing a return may be worth doing to claim refundable credits like the Earned Income Tax Credit (EITC).

State income tax rules vary. Some states do not tax SSDI at all; others tax it under the same rules as the federal government. You will need to check your state's specific rules or contact your state tax authority.

Key Takeaways

  • SSDI payments are not taxable by themselves, but combined income from SSDI plus other sources may trigger a tax filing requirement.
  • The IRS uses a combined income formula: your adjusted gross income plus nontaxable interest plus half your SSDI benefits.
  • If your combined income exceeds $25,000 (single) or $32,000 (married filing jointly), part of your SSDI becomes taxable.
  • State tax rules on SSDI vary widely, and some states tax SSDI while others do not.
  • Filing a return even when you owe no tax can result in a refund if you are owed credits like the EITC.

How the IRS calculates whether your SSDI is taxable

The IRS does not tax SSDI directly. Instead, it looks at your total income picture. The calculation starts with your adjusted gross income (AGI) — this includes wages, self-employment income, interest, dividends, and other sources, but excludes SSDI itself.

To this, the IRS adds nontaxable interest (such as interest from municipal bonds) and half of your SSDI benefits. This sum is your combined income. If combined income stays below a threshold amount, none of your SSDI is taxable. If it exceeds the threshold, up to 85 percent of your SSDI may become taxable.

The threshold amounts are fixed and do not change year to year. For a single filer, the first threshold is $25,000; for married filing jointly, it is $32,000. If your combined income exceeds a second threshold ($34,000 for single filers, $44,000 for married filing jointly), the calculation becomes more complex, but the maximum taxable portion remains 85 percent of your benefits.

When you must file a federal tax return

You must file a federal return if your gross income (not counting SSDI) meets the standard threshold for your age and filing status. For 2024, a single person under 65 must file if gross income is $14,600 or more; a single person 65 or older must file if gross income is $18,350 or more. These amounts change annually.

Even if your gross income is below the filing threshold, you should consider filing if you had income tax withheld from wages or if you are owed a refundable credit. The EITC, for example, is refundable — meaning you can receive money back even if you owe no tax. If you work part-time while on SSDI and earned less than the threshold, filing could result in a refund.

To find the current filing thresholds for your situation, visit the IRS website or call the IRS at 1-800-829-1040. The Social Security Administration (SSA) does not determine tax filing requirements; the IRS does.

State income tax on SSDI

Thirty-seven states do not tax SSDI benefits at all. However, thirteen states tax SSDI under their own rules, which may differ from federal rules. Some states follow the federal combined income formula; others use different thresholds or tax SSDI as regular income.

The states that tax SSDI are Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. If you live in one of these states, you may owe state income tax on SSDI even if you owe no federal tax.

Contact your state tax authority or department of revenue to learn the exact rules in your state. Many state websites have worksheets or calculators to help you determine whether you owe state tax on SSDI.

What documents you need to file

To file your federal return, you will need your Social Security number, your SSDI benefit statement (Form SSA-1099, which the SSA mails in January), and documentation of any other income. If you worked, you will need your W-2 forms from employers or a Schedule C if you were self-employed.

The Form SSA-1099 shows your total SSDI benefits for the year in Box 5. This is the amount you use in the combined income calculation, even though SSDI itself is not reported as income on your return. Keep this form with your tax records.

If you file electronically, you can file for free through the IRS Free File program if your income is below a certain threshold (the limit changes yearly). If your income is higher or you prefer to file on paper, you can purchase tax software or work with a tax preparer. The SSA does not provide tax preparation services, but many community organizations and libraries offer free tax help through the Volunteer Income Tax information (VITA) program.

How to report SSDI on your tax return

SSDI benefits are reported on Form 1040, the main federal income tax return. You do not report SSDI in the income section; instead, you report it on the worksheet that determines whether any of your benefits are taxable. The worksheet uses your combined income to calculate the taxable portion.

If you use tax software, the program will walk you through the questions needed to complete this worksheet. If you file on paper, you will use the worksheet in the Form 1040 instructions. The worksheet is not filed with your return; it is kept for your records.

If part of your SSDI is taxable, that amount is added to your other income on Form 1040. You then calculate your total tax owed based on your filing status and tax bracket. Many people find it easier to use tax software or a preparer for this step, since the combined income calculation can be confusing.

What happens if you do not file when you should

If you are required to file but do not, the IRS may assess penalties and interest on any tax owed. However, if you owe no tax and are not owed a refund, the penalty is usually not applied. The risk is greater if you owe tax and do not file.

If you are owed a refund and do not file, you can still claim it, but only within three years of the original due date. After three years, the refund is forfeited. If you think you may be owed a refund from a prior year, you can file an amended return (Form 1040-X) to claim it.

If you are unsure whether you must file, contact the IRS or use the IRS Interactive Tax Assistant tool on the IRS website. You can also reach out to a VITA site in your area for free guidance.

Frequently Asked Questions

Do I have to report my SSDI to the IRS if I do not work?

Not necessarily. If SSDI is your only income and you have no other income sources, you do not have to file a federal return. However, if you have any other income — even a small amount of interest or a part-time job — you may be required to file. Check the IRS filing thresholds for your age and filing status to be sure.

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

No. SSDI benefits are your own income and cannot be claimed as dependent income by a parent or guardian. However, if someone else pays more than half your living expenses and you meet other dependent tests, they may still be able to claim you as a dependent based on other factors. The rules are complex; consult a tax preparer if this applies to you.

What if I work part-time while on SSDI and earn below the filing threshold?

You are not required to file a federal return if your wages fall below the threshold for your age and status. However, you should consider filing anyway if you had income tax withheld from your paychecks, because you may be owed a refund. You should also file if you think you may have access to for the EITC, which can result in a refund even if you owe no tax.

Will filing taxes affect my SSDI benefits?

Filing a tax return does not change your SSDI benefit amount. The SSA does not use your tax return to calculate benefits. However, if you are working and earning above the substantial gainful activity (SGA) threshold, that work activity — not your tax filing — could affect your benefits. Report work income to the SSA, not just to the IRS.

Where do I get my Form SSA-1099?

The SSA mails Form SSA-1099 to you in January each year if you received SSDI during the prior year. If you do not receive it by early February, you can request a replacement by calling the SSA at 1-800-772-1213 or by visiting your local Social Security office. You can also view and print your SSA-1099 online through your my Social Security account.
