Whether You Must File Depends on Your Total Income, Not Just SSDI
You must file a federal tax return if your total income — including SSDI, wages, interest, and other sources — exceeds a threshold set by the IRS each year. SSDI itself is not taxable income in most cases, but it counts toward the threshold that determines whether you file. The threshold changes annually and depends on your age and filing status.
If you are under 65 and single, you must file if your non-SSDI income (wages, self-employment, interest, dividends) is $14,600 or more in 2024. If you are 65 or older and single, the threshold is $18,150. These numbers shift each year, so you need to check the current year's IRS threshold before deciding.
The key point: SSDI does not push you over the filing threshold by itself. Only other income counts. But if you have even a small amount of wages or self-employment income alongside SSDI, you may cross that threshold and be required to file.
Key Takeaways
- SSDI is not taxable income, but you must file if your other income (wages, self-employment, interest) exceeds the IRS threshold for your age and filing status.
- The IRS threshold for filing changes each year and depends on whether you are under 65, 65 or older, married, or single.
- If you have any wages or self-employment income while receiving SSDI, check the current year's threshold to see if you must file.
- Filing even when not required can result in a refund if taxes were withheld from wages or if you are due the Earned Income Tax Credit.
How to Find Your Filing Threshold for This Year
The IRS publishes filing thresholds on its website each January. You can find them by searching "IRS filing requirements" or visiting IRS.gov directly. The threshold depends on three things: your age (under 65 or 65 and older), your filing status (single, married filing jointly, head of household), and the tax year you are filing for.
For 2024, the thresholds are $14,600 for a single person under 65, and $18,150 for a single person 65 or older. If you are married filing jointly and both spouses are under 65, the threshold is $29,200. These amounts explore only to earned income (wages and self-employment) and unearned income (interest, dividends, capital gains). SSDI does not count toward these thresholds.
Write down the threshold for your situation and your tax year. If your non-SSDI income is below that number, you are not required to file. If it is at or above that number, you must file.
When Filing Is Required Even If You Are Below the Threshold
You must file a return even if your income is below the threshold if you had taxes withheld from your paychecks or if you are self-employed and owe self-employment tax. Withholding happens automatically when you work, and filing allows you to claim a refund of any overpayment.
You must also file if you are self-employed and your net earnings from self-employment are $400 or more, regardless of your total income. Self-employment tax is separate from income tax and applies to income from your own business or gig work.
Additionally, if you received a Form 1099 for any reason — interest, dividends, freelance work, or other income — you should file to report it, even if the amount is small. The IRS matches 1099 forms to tax returns, and not filing when you received one can trigger a notice.
Why Filing Can Benefit You Even When Not Required
Filing a tax return when you are not required to can result in money back. If you had taxes withheld from wages, filing allows you to claim a refund. If you earned less than the threshold but had any withholding, you likely overpaid and are due a refund.
You may also be due the Earned Income Tax Credit (EITC) if you had wages and your income is below a certain level. The EITC is a refundable credit, meaning you can receive money even if you owe no tax. To claim the EITC, you must file a return. SSDI does not count as earned income for the EITC, but wages do.
If you have dependents, you may also be due the Child Tax Credit or other credits that require filing. Filing is often worth doing even when not required, because the refund or credit can exceed what you would owe.
How SSDI Interacts With Other Income on Your Tax Return
When you file, SSDI does not appear as income on your return. You report only your wages, self-employment income, interest, dividends, and other taxable sources. The IRS does not tax SSDI benefits themselves.
However, if you have both SSDI and other income, that other income is reported normally. If you worked part-time while receiving SSDI, you report those wages on your return. If you earned interest on a savings account, you report that. SSDI stays off the return entirely.
This matters because it keeps your taxable income lower than it would be if SSDI counted. Your tax liability is based only on the income the IRS considers taxable, which excludes SSDI.
What to Do If You Are Unsure Whether to File
If you are uncertain whether your income exceeds the threshold, the safest choice is to file. Filing when you are not required does not create a penalty. If you file and owe nothing, you straightforward owe nothing. If you file and are due a refund, you receive it.
Not filing when you are required to can result in penalties and interest, even if you owe no tax. The IRS can assess a failure-to-file penalty if you do not file by the important date, even if you have no tax liability.
If you need help determining whether you must file, you can contact the IRS directly at 1-800-829-1040, or you can use the IRS Interactive Tax Assistant on IRS.gov. Both are free resources. You can also work with a tax professional or visit a free tax preparation site in your area.
Filing important date and Extensions for SSDI Recipients
The federal tax filing important date is April 15 each year, unless that date falls on a weekend or holiday. If you cannot file by that date, you can request an automatic extension by filing Form 4868 with the IRS. The extension gives you until October 15 to file your return.
Receiving SSDI does not change the filing important date or give you an automatic extension. You must request an extension if you need one. Requesting an extension does not extend the important date to pay taxes you owe — only the important date to file the return itself. If you owe tax, you should pay it by April 15 to avoid interest and penalties.
If you file late without requesting an extension, the IRS will assess a failure-to-file penalty. This penalty is usually 5 percent of the unpaid tax for each month the return is late, up to 25 percent. Filing on time or requesting an extension before the important date avoids this penalty.
Frequently Asked Questions
Do I have to report my SSDI income on my tax return?
No. SSDI is not taxable income and does not appear on your federal tax return. You report only your wages, self-employment income, interest, dividends, and other taxable sources. SSDI stays off the return entirely.
What if I worked part-time while receiving SSDI — do I have to file?
You must file if your wages exceed the IRS threshold for your age and filing status. For 2024, that is $14,600 for a single person under 65. Even if your wages are below the threshold, filing may be worth doing if taxes were withheld from your paychecks, because you may receive a refund.
Can I get in trouble with the SSA if I file taxes?
No. Filing a tax return does not affect your SSDI benefits. The SSA and the IRS are separate agencies. Filing taxes and receiving SSDI are independent. However, if you earned wages, you must report that to the SSA if it affects your work incentives or trial work period.
What if I received a 1099 form while on SSDI?
You should file a tax return to report the income shown on the 1099, even if the amount is small. The IRS matches 1099 forms to tax returns, and not filing when you received one can trigger a notice or audit. The income on the 1099 counts toward your filing threshold.
Where can I get help filing my taxes if I am on SSDI?
Free tax preparation is available through VITA (Volunteer Income Tax information) sites in your area, which serve people with low to moderate income. You can find a VITA site by searching "VITA near me" or calling 211. Many libraries and community centers also offer free tax help during tax season.
