You must file taxes if your income exceeds the IRS threshold for your filing status, even if all your income is SSDI

Whether you file taxes depends on how much total income you received in the year, not on whether that income came from SSDI. SSDI itself is not taxable income. But if you have other income—wages, self-employment earnings, interest, dividends, or other benefits—you add that to your SSDI and compare the total to the IRS filing threshold for your age and filing status.

The IRS filing thresholds change each year. For 2024, a single person under 65 must file if their gross income was $14,600 or more. A single person 65 or older must file if their gross income was $18,150 or more. If you are married filing jointly, the thresholds are higher. These numbers do not include SSDI in the calculation—only other income sources count.

If your only income in the year was SSDI, you do not have to file a federal income tax return. But if you had any other income at all, you need to check whether your total crossed the threshold. Many people on SSDI have part-time work, rental income, or a spouse's income, which is why filing becomes necessary.

Key Takeaways

  • SSDI payments themselves are never taxable, so they do not count toward the IRS filing threshold.
  • You must file if your total income from all other sources exceeds the IRS threshold for your age and filing status in that year.
  • The IRS thresholds are higher for people 65 and older, and higher still for married couples filing jointly.
  • Even if you do not owe taxes, filing may be worth doing if you had taxes withheld or if you are may have access to to a refundable tax credit like the Earned Income Tax Credit.

How SSDI income is treated differently from other benefits

SSDI is one of the few benefit programs where the payments themselves are never subject to federal income tax, regardless of how much you receive or what other income you have. This is different from Social Security retirement benefits, which can be partially taxable if your combined income exceeds certain thresholds. It is also different from Supplemental Security Income (SSI), which is also not taxable but is a separate program with different rules.

Because SSDI is not taxable, the IRS does not count it when calculating whether you must file. If you received $2,000 per month in SSDI for the full year, that $24,000 does not appear on your tax return and does not push you over the filing threshold. Only income from other sources—W-2 wages, 1099 self-employment income, interest, capital gains, or other taxable benefits—counts toward the threshold.

This rule applies even if you are working while on SSDI. Your SSDI payments stay non-taxable. Your wages are taxable and count toward the threshold. This is one reason the Social Security Administration has work incentive programs: your SSDI does not create a tax burden, so you can earn money without automatically owing federal income tax on the SSDI portion.

When you have earned income alongside SSDI

If you work while receiving SSDI, your wages are taxable income and must be counted toward the filing threshold. The amount of SSDI you receive does not change based on your tax filing status, and your SSDI does not become taxable because you worked. But you do have to report your wages to the IRS if they exceed the threshold.

Many people on SSDI use work incentive programs like the Student Earned Income Exclusion or Plan to Achieve Self-Support (PASS) to keep their SSDI benefits while working. These programs reduce the amount of earnings that count toward the Social Security Administration's benefit calculation, but they do not change the IRS filing threshold. You still must file if your total income—including SSDI (which counts as zero) plus your wages—exceeds the threshold.

For example, if you are 35 years old, single, and received $18,000 in SSDI and $8,000 in wages during 2024, your total income for IRS purposes is $8,000 (SSDI does not count). Since $8,000 is below the $14,600 threshold, you would not have to file. But if you earned $10,000 in wages, your total would be $10,000, still below the threshold. If you earned $15,000 in wages, your total would be $15,000, which exceeds $14,600, so you would have to file.

Income from sources other than work

SSDI recipients sometimes have income from sources beyond wages: interest from a savings account, dividends from investments, rental income, or income from a spouse or household member. All of these count toward the IRS filing threshold, just as wages do.

If you are married and file jointly, your spouse's income counts toward the threshold even if your spouse is not on SSDI. If you have rental property and receive rent payments, that rental income counts. If you have a bank account earning interest, that interest counts. The rule is straightforward: add up all income from all sources except SSDI, and compare the total to the threshold for your filing status and age.

Some SSDI recipients also receive other Social Security benefits—for instance, a spouse or child on the same Social Security record. Those other benefits may be taxable depending on your combined income. SSDI itself is not, but spousal or survivor benefits can be. If you are unsure whether another benefit is taxable, the Social Security Administration will send you a form SSA-1099 showing what portion, if any, is taxable.

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 contact you. The consequences depend on whether you owe taxes. If you had taxes withheld from wages or other income, you may be owed a refund. Not filing means you do not receive that refund. If you owe taxes and do not file, penalties and interest accrue, and the IRS can pursue collection.

For SSDI recipients, the most common scenario is that they had taxes withheld from wages but do not owe any tax because their total income is low. In that case, filing allows them to claim a refund of the taxes withheld. This is especially true if they are may have access to to a refundable tax credit like the Earned Income Tax Credit (EITC), which can result in a payment from the IRS even if no tax is owed.

Filing also creates a record with the IRS and Social Security. If you have questions later about your income or benefits, having filed a return makes it easier to resolve them. For people on SSDI who work, filing is often the clearest way to document your earnings and show that you are complying with work incentive rules.

Using Form SSA-1099 to determine what to report

Each January, the Social Security Administration sends Form SSA-1099 to anyone who received SSDI during the previous year. This form shows the total SSDI you received. It will show $0 in the taxable portion because SSDI is never taxable. You do not report this form on your tax return—it is for your records and for reference.

The SSA-1099 is useful because it confirms the exact amount of SSDI you received, which you can use to verify your records. But it does not tell you whether you must file. To determine that, you need to add up all your other income sources and compare the total to the IRS threshold.

If you also received other Social Security benefits—such as spousal benefits or survivor benefits—you may receive a separate SSA-1099 or a combined form showing both SSDI and other benefits. The taxable portion of non-SSDI benefits will be shown separately. That taxable portion must be included in your income calculation for IRS purposes.

State income tax requirements

Federal income tax and state income tax are separate. Even if you do not have to file a federal return, your state may require you to file a state return. Most states do not tax SSDI, but some states tax other income sources differently than the federal government does.

For example, some states do not tax Social Security benefits at all, while others tax them under certain conditions. A few states have no income tax at all. If you live in a state with an income tax, you should check your state's rules separately from the federal threshold. Your state tax agency or a tax professional can tell you whether you must file a state return.

The state filing threshold is often different from the federal threshold, and the definition of taxable income may differ as well. If you move during the year or live in a state with a local income tax, those rules explore too. This is one reason many SSDI recipients consult a tax professional or use free tax preparation services—the rules vary by location.

Free tax preparation resources for SSDI recipients

The IRS offers free tax preparation through the Volunteer Income Tax information (VITA) program, which serves people with low to moderate income. VITA sites are located in libraries, community centers, and nonprofits across the country. You can find a site near you through the IRS website or by calling 211.

The Tax Counseling for the Elderly (TCE) program offers free tax help to people 60 and older. Both programs are staffed by trained volunteers and are designed for people who cannot afford to pay for tax preparation. If you are on SSDI, your income likely qualifies you for free help.

Some disability advocacy organizations and legal aid societies also offer tax preparation help or can refer you to free resources. If you have questions about how your SSDI interacts with your tax situation, these free services can walk you through the process and help you understand what you must report.

Frequently Asked Questions

If I only received SSDI and no other income, do I have to file taxes?

No. SSDI is not taxable income, so if it was your only income source in the year, you do not have to file a federal return. You would only file if you had other income—wages, interest, rental income, or other benefits—that pushed your total above the IRS threshold for your age and filing status.

I had taxes withheld from my wages. Do I still have to file if my total income is below the threshold?

You are not required to file, but you should file to claim a refund of the taxes withheld. You may also be may have access to to the Earned Income Tax Credit or other refundable credits, which can result in a payment from the IRS. Filing takes a few hours and can put money back in your pocket.

Does my SSDI count as income when I explore for other benefits or programs?

That depends on the program. For federal income tax purposes, SSDI does not count. But for means-tested programs like Medicaid, SNAP, or housing information, SSDI usually does count as income toward the may be able to access limit. Check the rules for each program separately.

What if I am married and my spouse works? Do we have to file?

If you file jointly, you add your spouse's income to yours (SSDI still does not count) and compare the total to the married filing jointly threshold. If the combined income exceeds the threshold, you must file. If your spouse has income but you do not, your spouse may have to file even if you are on SSDI.

Can I file taxes if I am on SSDI and also receiving SSI?

Yes. SSI is also not taxable, so it does not count toward the filing threshold either. But if you have other income from any source, you count that toward the threshold. Some people receive both SSDI and SSI, and the same rule applies: only non-SSDI, non-SSI income counts for tax purposes.
