Most SSDI recipients do not have to file federal taxes, but some do

Whether you file taxes depends on how much money you received that year and whether you have other income. Social Security Disability Insurance (SSDI) itself is usually not taxable — meaning the SSA does not count it as income the IRS cares about. But if you earned wages, had investment income, or received other benefits alongside SSDI, you may cross a threshold that requires you to file.

The IRS uses a formula called "combined income" to decide. It adds half your SSDI to any wages, interest, dividends, or other income you had. If that total exceeds a certain amount, you owe a tax return. The threshold depends on your filing status and whether you are married.

Even if you do not have to file, you may want to — especially if your employer took taxes out of your paychecks. Filing lets you claim a refund.

Key Takeaways

  • SSDI payments themselves are not taxable income, but they count toward the "combined income" formula the IRS uses to decide if you must file.
  • If your combined income (half your SSDI plus all other income) exceeds $25,000 for a single filer or $32,000 for a married couple filing jointly, you must file a federal tax return.
  • Wages, self-employment income, interest, dividends, and rental income all count toward the threshold and may push you into filing territory.
  • If taxes were withheld from your paychecks or you had a tax credit, filing a return can get you a refund even if you are not required to file.

How the IRS calculates whether you must file

The IRS does not use your SSDI amount directly. Instead, it uses a two-step calculation. First, add half of your SSDI to all your other income — wages, self-employment earnings, interest, dividends, capital gains, rental income, and any other sources. This total is your "combined income."

Next, compare that combined income to the filing threshold for your status. For a single person, the threshold is $25,000. For a married couple filing jointly, it is $32,000. For a married person filing separately, it is $25,000. If your combined income meets or exceeds the threshold, you must file.

Example: You received $15,000 in SSDI and earned $8,000 in wages. Half your SSDI is $7,500. Your combined income is $7,500 + $8,000 = $15,500. Since $15,500 is below $25,000, you do not have to file.

Another example: You received $20,000 in SSDI and earned $12,000 in wages. Half your SSDI is $10,000. Your combined income is $10,000 + $12,000 = $22,000. Still below $25,000, so no filing requirement.

When you must file even though SSDI is not taxable

SSDI itself generates no tax liability. The SSA does not withhold federal income tax from your SSDI check, and you do not owe tax on those dollars. But other income does. If you worked part-time, had a side business, received interest from a savings account, or got rental income, that money is taxable.

If your taxable income alone (not counting SSDI) exceeds the standard deduction for your filing status, you must file. For 2024, the standard deduction is $14,600 for a single person and $29,200 for a married couple filing jointly. But the SSDI formula is stricter — it counts half your SSDI toward the threshold, so you may have to file even if your wages alone are below the standard deduction.

The reason: Congress wanted to may support people with SSDI do not hide other income. The formula casts a wider net than the standard deduction alone.

Why you might file even if you do not have to

If your employer withheld federal income tax from your paychecks, filing a return can get that money back. The IRS will not refund taxes you did not owe unless you file and claim the refund. This is common for people who worked part of the year and then went on SSDI, or who work part-time while on SSDI.

You may also have a tax credit you can claim — the Earned Income Tax Credit (EITC), for example, or the Child Tax Credit. These credits can result in a refund even if you owed no tax. To get the refund, you must file a return.

Filing is free. You can use IRS Free File if your income is below a certain threshold, or you can use tax software or a tax preparer. The effort of filing can be worth it if you are owed a refund.

How to report SSDI on your tax return

If you do file, SSDI appears on your return but does not increase your tax. You will receive a form SSA-1099 from the Social Security Administration by January 31 each year. This form shows how much SSDI you received. You enter this amount on line 5b of Form 1040 (the main federal income tax form), but you do not add it to your taxable income.

Instead, you use the combined income formula described above to determine your filing requirement and tax liability. Your actual taxable income comes from wages, self-employment, interest, dividends, and other sources — not from SSDI.

If you use tax software or a tax preparer, tell them you received SSDI. They will know how to handle it correctly. Do not assume SSDI is taxable just because you have to report it on the form.

State taxes and SSDI

Most states do not tax SSDI either. However, a few states have their own rules. Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont all tax SSDI under certain conditions — usually when your income exceeds a state-specific threshold.

If you live in one of these states and your income is high enough to require a federal return, check your state's tax rules or contact your state tax authority. You may owe state tax even if you owe no federal tax, or vice versa. State rules change, so verify the current rules for your state before filing.

What to do if you are unsure whether to file

Calculate your combined income using the formula above: half your SSDI plus all other income. If that total is $25,000 or more (or $32,000 if married filing jointly), you must file. If it is below that threshold, you do not have to file — but you may want to if taxes were withheld from your pay.

You can also contact the IRS directly. Call 1-800-829-1040 (the main IRS line) and ask whether you must file based on your income. Have your SSDI amount and other income figures ready. The IRS can give you a yes-or-no answer.

If you worked and had taxes withheld, filing is almost always worth your time, even if you are not required to. A refund is money the government owes you.

Frequently Asked Questions

Do I have to report SSDI on my tax return if I do not have to file?

No. If you are not required to file a federal tax return, you do not have to report your SSDI to the IRS. The SSA reports it to the IRS separately, so the IRS already knows you received it.

What if I worked for only part of the year before going on SSDI?

Your combined income for that year includes all wages you earned, plus half your SSDI. If the total exceeds the threshold, you must file. You may also be owed a refund if your employer withheld taxes from your paychecks, since you earned less than the standard deduction for the full year.

Can SSDI push me into owing taxes on my other income?

No. SSDI itself is not taxable and does not increase the tax you owe on wages or other income. However, the combined income formula means SSDI counts toward the threshold that decides whether you must file at all. Once you file, your tax is based only on your taxable income — wages, interest, and so on.

If I am married and my spouse does not receive SSDI, do we file jointly?

You can file jointly or separately. If you file jointly, the threshold is $32,000 combined income. If you file separately, each of you uses the $25,000 threshold. Filing jointly is usually better because it may lower your overall tax, but run the numbers both ways or ask a tax preparer to be sure.

What if I received SSDI for only part of the year?

Use the actual amount you received in that year. If you started SSDI in June and received $10,000 for the rest of the year, use $10,000 in the combined income formula, not the full annual amount. The SSA-1099 will show the exact amount you received.
