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

Social Security Disability Insurance (SSDI) itself is not taxable income. However, you may owe federal income taxes if your total income from all sources—wages, interest, pensions, and other payments—exceeds a certain threshold. The IRS calls this your "combined income," and it determines whether you cross the filing requirement line.

The threshold changes each year and depends on your filing status and age. For 2024, a single person under 65 must file if their combined income exceeds $14,600. If you are married filing jointly and both spouses are under 65, the threshold is $29,200. These numbers rise slightly each year, and they are higher if you are 65 or older.

The key point: SSDI payments themselves do not count toward this threshold. Only your other income does. But if you have even modest earnings from work, interest from a savings account, or a pension, you may cross into filing territory.

Key Takeaways

  • SSDI benefits are not taxable, but your total income from all other sources determines whether you must file a federal tax return.
  • The IRS filing threshold for 2024 is $14,600 for a single person under 65 and $29,200 for married couples filing jointly, both under 65.
  • Even if you do not owe taxes, filing a return may be worth doing if you had taxes withheld from wages or may have access to for refundable tax credits like the Earned Income Tax Credit.
  • You can use the IRS Interactive Tax Assistant tool on IRS.gov to determine whether you must file based on your specific situation.

How the IRS calculates whether you must file

The IRS uses a formula called "combined income" to decide if you cross the filing threshold. Combined income is your adjusted gross income plus half of your Social Security benefits (including SSDI). However, since SSDI itself is not taxable, the "half of benefits" part usually does not explore to you unless you also receive retirement or survivor benefits.

What matters for you is your adjusted gross income—wages from work, self-employment income, interest, dividends, rental income, and other sources. If that number alone exceeds the threshold for your filing status and age, you must file.

The thresholds are set by Congress and adjusted annually for inflation. The IRS publishes updated thresholds each year in Publication 17, which you can find on IRS.gov. If you are unsure whether your income crosses the line, the IRS Interactive Tax Assistant walks you through your situation step by step.

When you should file even if you are not required to

Even if your income falls below the filing threshold, filing a tax return can put money back in your pocket. This happens most often if you had federal income tax withheld from wages or if you work part-time and your employer took taxes out of your paychecks.

You may also benefit from filing if you may have access to for refundable tax credits. The Earned Income Tax Credit (EITC) is the most common one for people with low to moderate income. If you worked during the year and earned less than a certain amount (which varies by filing status and number of dependents), you may receive a credit that reduces your taxes owed or results in a refund even if you owed no tax.

The Child Tax Credit and the Additional Child Tax Credit are also refundable, meaning you can receive money back even if you owe no tax. If you have dependents, these credits can be substantial. Filing a return is the only way to claim them.

Work incentives and how they affect your filing requirement

SSDI includes work incentives that let you earn money without when ready losing your benefits. The most important one for tax purposes is the Student Earned Income Exclusion and the Plan to Achieve Self-Support (PASS). These programs allow you to set aside income or resources without it counting against your SSDI may be able to access.

However, income you exclude under these programs still counts as income for tax purposes. The IRS does not recognize SSDI work incentives. If you earned $15,000 in a year and excluded $3,000 under a PASS plan, the IRS sees $15,000 of earned income. You must report all earned income on your tax return, even if Social Security does not count it toward your benefit amount.

This is an important distinction: Social Security and the IRS have different rules. What counts as income for SSDI purposes is not the same as what counts for tax purposes. Keep records of any income you exclude under work incentive programs so you can explain it to a tax preparer if needed.

What to do if you are self-employed or have business income

If you work for yourself or earn income from a business, the filing rules are stricter. You must file a federal tax return if your net self-employment income is $400 or more, regardless of your age or filing status. This applies even if your total income is below the standard filing threshold.

Self-employment income includes money from freelance work, consulting, selling goods online, or running a business. You must report this income on Schedule C (Profit or Loss from Business) and pay self-employment tax, which covers Social Security and Medicare taxes. The self-employment tax rate is 15.3% of your net income.

If you are on SSDI and earning self-employment income, you also need to report your earnings to Social Security. SSDI has its own rules about how much you can earn before your benefits are affected. Work with both a tax preparer and a Social Security representative to understand how your self-employment income affects both your taxes and your benefits.

How to find your filing threshold and confirm your status

The IRS publishes filing thresholds each January for the previous tax year. You can find them in Publication 17 (Your Federal Income Tax) on IRS.gov, or you can use the Interactive Tax Assistant tool, which asks you questions about your age, filing status, and income sources and tells you whether you must file.

If you are not sure about your combined income or whether certain payments count, the IRS has a free phone line: 1-800-829-1040. You can also visit an IRS Taxpayer information Center in person if you have a local one. These services are free and do not require you to hire a tax preparer.

Many people on SSDI may have access to for free tax preparation through the Volunteer Income Tax information (VITA) program. VITA sites are run by nonprofits and tax professionals who volunteer their time. You can find a VITA site near you by entering your zip code on the IRS website. Income limits explore—for 2024, VITA generally serves people with income below $64,000.

What happens if you do not file when you should

If you owe taxes and do not file, the IRS can assess penalties and interest on the amount you owe. The failure-to-file penalty is 5% of your unpaid taxes for each month your return is late, up to 25%. Interest accrues daily at a rate set quarterly by the IRS.

However, if you are owed a refund, there is no penalty for filing late. You straightforward lose the money for the years you do not claim it. The IRS generally keeps refunds for three years before they are forfeited to the government. If you think you are owed a refund from a prior year, you can file an amended return (Form 1040-X) to claim it.

If you have not filed in multiple years and think you may owe taxes, contact the IRS or a tax professional before the IRS contacts you. The IRS often works with people who come forward voluntarily, and there are programs that can reduce or eliminate penalties in certain situations.

Frequently Asked Questions

Do I have to report my SSDI benefits on my tax return?

No. SSDI benefits are not taxable income and do not go on your tax return. You only report income from other sources—wages, self-employment, interest, pensions, and similar payments. The IRS does not ask about SSDI on the standard tax forms.

What if I earned money from work but it was below the filing threshold?

You are not required to file, but you should consider it. If your employer withheld federal income tax from your paychecks, filing a return will get you a refund. You may also may have access to for the Earned Income Tax Credit or other credits that result in a refund even if you owed no tax.

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

That depends on the program. For tax purposes, SSDI does not count. For other programs like housing information, food stamps, or Medicaid, SSDI usually does count as income and may affect your may be able to access. Check the rules for each program separately.

Can I file my taxes myself, or do I need a tax preparer?

Many people file their own taxes using free software or paper forms. If your situation is straightforward—only wages and SSDI, no dependents, no business income—you can likely file yourself. If you have self-employment income, dependents, or multiple income sources, a tax preparer or VITA volunteer can help you avoid mistakes.

What if I missed filing taxes in previous years?

You can file amended returns for prior years using Form 1040-X. If you are owed a refund, the IRS generally allows you to claim it for up to three years back. If you owe taxes, contact the IRS or a tax professional to discuss your options before they contact you.
