The short answer: it depends on how much you earn and what kind of income you have

You may have to file a tax return on Social Security Disability Insurance (SSDI) income, but most people who receive only SSDI do not. The deciding factor is whether your total income — including SSDI, wages, interest, and other sources — crosses a threshold the IRS sets each year. That threshold changes annually and depends on whether you are single, married, or head of household.

The tricky part is that SSDI itself is not automatically taxable the way wages are. But if you have other income, some of your SSDI may become taxable. This is different from how most people think about taxes, and it catches many people off guard.

Key Takeaways

  • If SSDI is your only income and it is below the IRS threshold for your filing status, you do not have to file a tax return.
  • If you have wages, self-employment income, interest, or other earnings in addition to SSDI, you may owe taxes even if your total is modest.
  • Up to 85 percent of your SSDI can become taxable income if your "combined income" (SSDI plus half your SSDI plus other income) exceeds a certain level.
  • Social Security sends Form SSA-1099 in January each year, showing how much SSDI you received; this is not the same as a W-2 and does not mean taxes were withheld.
  • Filing a return even when you do not owe can result in a refund if taxes were withheld from wages or other sources.

When SSDI becomes taxable income

SSDI becomes taxable only when your combined income exceeds a base amount set by the IRS. Combined income is calculated as your adjusted gross income plus nontaxable interest plus half of your SSDI benefits. If you are single and your combined income exceeds $25,000, some of your SSDI becomes taxable. If you are married filing jointly, the threshold is $32,000. If you are married filing separately, it is $0 — meaning any SSDI at all may be taxable.

The IRS then taxes either 50 percent or 85 percent of your SSDI, depending on how far your combined income exceeds the base amount. This is a formula, not a flat rate, and it can feel confusing because you are not taxed on the full amount of your benefits.

Example: You are single and receive $1,200 per month in SSDI ($14,400 per year). You also earn $15,000 in wages. Your combined income is $15,000 (wages) plus $7,200 (half your SSDI) = $22,200. This is below $25,000, so none of your SSDI is taxable. You owe tax only on the $15,000 in wages.

Another example: You are single and receive $1,200 per month in SSDI ($14,400 per year). You also earn $20,000 in wages. Your combined income is $20,000 (wages) plus $7,200 (half your SSDI) = $27,200. This exceeds $25,000 by $2,200. Up to 50 percent of your SSDI may become taxable, which means up to $7,200 of your benefits could be counted as income. The actual amount depends on the IRS formula.

Who has to file a return

You must file a tax return if your gross income is above the standard deduction for your filing status. The standard deduction changes each year. For 2024, the standard deduction is $14,600 for a single person, $29,200 for married filing jointly, and $21,900 for head of household. These numbers increase slightly each year.

If you receive only SSDI and no other income, and your SSDI is below the standard deduction, you do not have to file. However, if you have wages, self-employment income, interest from a bank account, or other earnings, you add those to any taxable portion of your SSDI to see if you exceed the standard deduction.

Even if you are not required to file, you may want to file anyway. If your employer withheld federal income tax from your wages, or if you made estimated tax payments, filing a return can get you a refund.

How to know what counts as income for this calculation

For the purpose of deciding whether your SSDI is taxable, the IRS counts most types of income. Wages from a job count. Self-employment income counts. Interest from savings accounts, money market accounts, and CDs counts. Dividends count. Rental income counts. Pensions count. Other Social Security benefits (retirement or survivor benefits) count.

Some types of income do not count toward the combined income calculation. Tax-exempt interest (such as interest from municipal bonds) does not count. Supplemental Security Income (SSI) does not count — it is a separate program and is never taxable. Veterans benefits do not count. Workers' compensation does not count.

The key is to gather statements from every source of income you received during the year. Your employer will send a W-2. Banks and investment firms send 1099 forms. Social Security sends Form SSA-1099 showing your SSDI. Pension providers send 1099-R forms. Add them all up to see whether you cross the threshold.

Form SSA-1099 and what it means

In January, Social Security mails Form SSA-1099 to everyone who received SSDI during the previous year. This form shows the total amount of benefits you received. It is not a tax bill, and it does not mean taxes were withheld from your benefits — they were not. It is straightforward a record of income, similar to a W-2 from an employer.

You will need this form to file your tax return, because the IRS needs to know how much SSDI you received. Keep it with your other tax documents. If you lose it, you can request a replacement from Social Security by calling 1-800-772-1213 or visiting your local Social Security office.

The amount on Form SSA-1099 is the gross amount you received, before any deductions. If you had Medicare premiums deducted from your SSDI, the form still shows the full amount before the deduction. This is the number you use for tax purposes.

What to do if you think you owe taxes

If your combined income exceeds the threshold and you think some of your SSDI is taxable, you have two options. You can file a tax return and pay the tax owed. Or, if you expect to owe tax in future years as well, you can ask Social Security to withhold federal income tax from your SSDI payments.

To request withholding, you fill out Form W-4V and send it to your local Social Security office or mail it to Social Security. You choose the withholding rate — typically 7, 10, 15, or 25 percent of your benefits. Social Security will then withhold that amount each month and send it to the IRS on your behalf. This does not reduce your SSDI payment; it straightforward sets aside part of it for taxes.

Many people find withholding easier than filing a return and paying a lump sum. Others prefer not to withhold because they want the full SSDI payment each month. There is no right answer — it depends on your situation and your preference.

State taxes on SSDI

Most states do not tax SSDI income. However, a small number of states do tax it under certain circumstances. Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont all tax SSDI in some form, though most have exemptions or special rules for people with lower incomes.

If you live in one of these states, contact your state tax authority or a tax professional to find out whether you owe state tax on your SSDI. The rules vary by state and change periodically, so it is worth checking directly rather than relying on general information.

Frequently Asked Questions

Do I have to pay taxes on my SSDI if I do not work?

Only if your combined income (SSDI plus half your SSDI plus other income like interest or pensions) exceeds $25,000 (single) or $32,000 (married filing jointly). If SSDI is your only income, you almost certainly do not owe federal tax.

What if I work part-time and receive SSDI?

Your wages count toward the combined income calculation. If your wages plus half your SSDI plus any other income exceeds the threshold, some of your SSDI becomes taxable. You may owe federal income tax even if your total earnings are modest.

Can I get a refund if I file a tax return on SSDI?

Yes. If your employer withheld federal income tax from your wages, or if you made estimated tax payments, filing a return can result in a refund even if you do not owe tax on your SSDI.

Do I need to file taxes every year I receive SSDI?

Only if your income exceeds the filing threshold for your status. If you receive only SSDI and no other income, and your SSDI is below the standard deduction, you do not have to file. If your situation changes — you start working, receive a pension, or have other income — you may need to file that year.

What happens if I do not file when I should have?

The IRS may assess penalties and interest if you owed tax and did not file. If you are unsure whether you were required to file, contact the IRS at 1-800-829-1040 or consult a tax professional. If you are owed a refund, there is no penalty for filing late, but you have a time limit to claim it.
