You may have to file taxes even though SSDI itself is not taxable

Social Security Disability Insurance (SSDI) benefits are not taxable income — the federal government does not tax the monthly payment you receive. However, you still may be required to file a federal tax return if you have other income, such as wages from work, interest, dividends, or self-employment earnings. The filing requirement depends on your total income from all sources, not on whether you receive SSDI.

The IRS does not count SSDI as income when calculating whether you must file. But if you earned money through work — even part-time or temporary work — that income counts toward the filing threshold. The threshold changes each year and depends on your age and filing status.

Many people on SSDI work part-time or have other income sources. If your earned income or unearned income (like interest) exceeds the annual threshold for your situation, you must file a return, even if no tax is owed. Filing when required protects you from penalties and keeps your tax record current, which matters if you later need to prove income for other programs.

Key Takeaways

  • SSDI payments themselves are never taxable, so they do not count toward the income threshold for filing a tax return.
  • You must file a return if your earned income, unearned income, or both exceed the IRS threshold for your age and filing status in that year.
  • The filing threshold varies by year and by whether you are single, married, or over 65 — check the IRS website or Form 1040 instructions for the current year.
  • Filing a return when required protects you from penalties and creates a record of your income, which some programs and lenders may request.
  • If you work and receive SSDI, you may also need to report your earnings to Social Security to avoid overpayment, which is separate from filing taxes.

How the IRS filing threshold works

The IRS sets a minimum income level — called the filing threshold — above which you must file a return. This threshold is not the same as the tax you owe. You can have income below the threshold and owe no tax; you can have income above the threshold and owe no tax but still must file. The threshold changes each year and depends on your age and filing status.

For 2024, the threshold for a single person under 65 is $14,600 in earned income. For a single person 65 or older, it is $18,350. If you are married filing jointly and both spouses are under 65, the threshold is $29,200. These numbers are adjusted annually for inflation, so the 2025 thresholds will be different. You can find the current year's thresholds in the instructions to Form 1040 on the IRS website or by calling the IRS at 1-800-829-1040.

SSDI does not count toward this threshold. If you earned $10,000 from part-time work and received $15,000 in SSDI, your filing threshold is based only on the $10,000. You would not be required to file in that scenario (assuming you are under 65 and single). But if you earned $15,000 and received $15,000 in SSDI, you would be required to file because your earned income alone exceeds the threshold.

When you have earned income from work

If you work while on SSDI, you must report your wages to both the IRS (through a tax return) and to Social Security (through a work report). These are two separate obligations. The IRS cares whether you earned enough to file a return. Social Security cares about your earnings because they affect your SSDI payment under the Substantial Gainful Activity (SGA) rules and the Trial Work Period.

Earned income includes wages from an employer, net profit from self-employment, and certain other compensation. It does not include SSDI, interest, dividends, rental income, or gifts. If your earned income exceeds the filing threshold for your age and status, you must file a return — even if you will owe no federal tax because of deductions or credits.

Many people on SSDI use the Plan to Achieve Self-Support (PASS) or other work incentives to keep more of their earnings without losing benefits. These programs do not change your tax filing obligation, but they do change what you must report to Social Security. Keep records of all earnings and any work expenses you claim, because you may need them for both your tax return and your Social Security work report.

Unearned income and the filing requirement

Unearned income includes interest, dividends, capital gains, rental income, and certain other sources. The filing threshold for unearned income is lower than for earned income. For 2024, a single person under 65 with only unearned income must file if that income exceeds $1,250. For a single person 65 or older, the threshold is $3,150.

If you have both earned and unearned income, the rules are more complex. Generally, you must file if your earned income exceeds the earned-income threshold for your age, or if your unearned income exceeds the unearned-income threshold, or if your gross income (earned plus unearned) exceeds a combined threshold. The IRS Form 1040 instructions for the current year spell out the exact rules for your situation.

Many people on SSDI have savings or investments that generate interest or dividends. If that unearned income is small — under $1,250 for most people — you do not have to file. But if you have a larger account or receive distributions from a retirement account, you may cross the threshold and need to file, even though SSDI itself remains untaxed.

Filing when you owe no tax

You can file a return and owe no federal income tax. This happens when your deductions and credits reduce your tax liability to zero. Many people on SSDI file returns even when they owe nothing because filing protects them from penalties and creates an official record of their income.

If you are required to file and do not, the IRS can assess a failure-to-file penalty. The penalty is usually 5 percent of the unpaid tax for each month the return is late, up to 25 percent. If you owe no tax, the penalty is zero — but you still violated the filing requirement. The IRS may contact you, and a missing return can complicate future dealings with other agencies that request your tax records.

If you file and owe no tax, you may still benefit from filing. The IRS offers credits like the Earned Income Tax Credit (EITC) that reduce your tax below zero, resulting in a refund. If you work part-time and have low income, you may be may have access to to the EITC even if you owe no tax. Filing is the only way to claim it.

Reporting SSDI on your tax return

You do not report SSDI as income on your tax return. Line 5 of Form 1040 asks for "interest," and line 7 asks for "capital gain or loss" — SSDI does not go on either line. The form has no line for SSDI because it is not taxable income.

However, the IRS may send you a notice if your return shows very low income but you received SSDI. This is not an audit or a problem — it is a routine check. You can respond by explaining that SSDI is not taxable and providing a copy of your Social Security statement (Form SSA-1099) if requested. Keep a copy of your SSDI award letter or your online Social Security account statement as proof that you received benefits.

If you file a joint return with a spouse, only your spouse's income counts toward the filing threshold (unless your spouse also receives SSDI, in which case neither spouse's SSDI counts). Make sure your tax preparer or software knows that SSDI is not taxable, so it does not accidentally appear on your return.

Coordinating with Social Security reporting

Filing a tax return and reporting earnings to Social Security are separate steps. The IRS and Social Security do not automatically share information about your earnings, so you must report to both if you work.

Social Security requires you to report your monthly earnings if you are under full retirement age and working. The amount you earn affects your SSDI payment under the SGA threshold (currently $1,550 per month in 2024, though this changes annually) and the Trial Work Period rules. If you exceed SGA, your benefits may stop, but you enter a grace period where you can test your ability to work without when ready losing coverage.

Your tax return shows your annual earnings. Your Social Security work report shows your monthly earnings. These may not match exactly if you had irregular income during the year. Keep records of when you earned money so you can report accurately to both agencies. If you use a work incentive like PASS, you will also report to Social Security which expenses reduce your countable earnings.

What to do if you are unsure whether to file

Use the IRS Interactive Tax Assistant tool on the IRS website to answer a few questions about your income and filing status. The tool will tell you whether you must file. You can also call the IRS at 1-800-829-1040 and speak to a representative, though wait times can be long.

If you work with a tax preparer or use tax software, tell them you receive SSDI and ask them to confirm that SSDI is not being counted as income. A good preparer will know this, but it is worth confirming, especially if you also have other income sources.

If you are on a tight budget and cannot afford a paid preparer, the IRS offers free tax preparation through the Volunteer Income Tax information (VITA) program. VITA sites are run by nonprofits and community organizations and serve people with low to moderate income. You can find a VITA site near you on the IRS website.

Frequently Asked Questions

Do I have to file taxes if I only receive SSDI and no other income?

No. SSDI is not taxable income, so if it is your only income, you do not meet the filing threshold and are not required to file. However, if you have any earned income (wages, self-employment) or unearned income (interest, dividends) above the threshold for your age, you must file even if you also receive SSDI.

What if I worked part of the year and received SSDI the rest?

You must file if your earned income from work exceeds the threshold for your age and filing status. SSDI does not count toward the threshold. For example, if you are single and under 65, you must file if you earned more than $14,600 in 2024, regardless of how much SSDI you received.

Will filing a tax return affect my SSDI benefits?

Filing a tax return does not affect your SSDI payment. However, the income you report on your return must match what you report to Social Security. If you work, you must report your earnings to Social Security separately, and those earnings may affect your benefits under the SGA rules. The tax return itself does not trigger a benefit change.

Can I get a refund if I file and owe no tax?

Yes, if you have taxes withheld from wages or if you are may have access to to refundable credits like the Earned Income Tax Credit (EITC). Many people on SSDI who work part-time may have access to for the EITC, which can result in a refund even if you owe no tax. You must file to claim it.

What happens if I do not file when I am supposed to?

The IRS can assess a failure-to-file penalty, usually 5 percent of unpaid tax per month, up to 25 percent. If you owe no tax, the penalty is zero, but you still violated the requirement. A missing return can complicate future dealings with lenders, landlords, or agencies that request your tax records. It is safer to file when required.
