Whether your SSDI is taxed depends on your total income, not just the benefit itself

Social Security Disability Insurance (SSDI) payments may or may not be taxed by the IRS. The answer hinges on your combined income—a specific calculation that includes your SSDI, wages, interest, dividends, and certain other money you receive. If your combined income falls below a threshold set by the IRS, your SSDI is not taxed. If it exceeds that threshold, a portion of your benefit becomes taxable.

The IRS does not automatically tax SSDI the way it taxes a paycheck. Instead, you calculate whether you owe tax on it using a formula, and you report the result on your tax return. Many people receiving SSDI owe no federal tax at all because their combined income is too low.

Key Takeaways

  • SSDI becomes taxable only if your combined income (SSDI plus other income) exceeds $25,000 for a single filer or $32,000 for a married couple filing jointly.
  • Combined income includes wages, self-employment income, interest, dividends, and certain other sources—but not all income counts the same way.
  • If you do owe tax on SSDI, you can request that the Social Security Administration withhold federal income tax from your monthly benefit to avoid a large bill at tax time.
  • You must file a tax return and do the calculation yourself; the IRS will not tell you whether your SSDI is taxable.

How the IRS calculates whether your SSDI is taxable

The IRS uses a two-step formula. First, you calculate your combined income by adding half of your SSDI to all your other income sources. This half-SSDI figure is what makes the calculation work—it is not the amount that gets taxed, just the number used to determine whether any of your benefit is taxable.

Second, you compare that combined income to a threshold. For a single filer with no dependents, the threshold is $25,000. For a married couple filing jointly, it is $32,000. For a married person filing separately, it is $0—meaning any combined income at all can trigger taxation. If your combined income is below the threshold, you owe no tax on your SSDI. If it is above, you move to the next step.

Example: You receive $1,200 per month in SSDI ($14,400 per year) and earn $15,000 from part-time work. Your combined income is $7,200 (half of $14,400) plus $15,000, which equals $22,200. Since $22,200 is below $25,000, none of your SSDI is taxable, even though you have other income.

What counts as income for this calculation

The IRS counts most money you receive, but the rules differ slightly depending on the source. Wages from a job count in full. Self-employment income counts in full. Interest and dividends count in full. Pensions and annuities count in full. Rental income counts in full.

Some income does not count toward combined income at all. Supplemental Security Income (SSI) does not count. Workers' compensation does not count. Certain veterans' benefits do not count. Gifts do not count. Loans do not count. Refunds of taxes you paid do not count.

The tricky part: if you are married and file separately, your spouse's income may count toward your combined income even if you do not live together. This is one reason married filers should consult a tax professional before deciding how to file.

How much of your SSDI actually becomes taxable

If your combined income exceeds the threshold, the amount of SSDI that is taxable is the lesser of two calculations. This means you use whichever number is smaller.

The first calculation: take 50 percent of the amount your combined income exceeds the threshold. The second calculation: take 85 percent of your total SSDI for the year. Whichever is smaller is the amount subject to tax.

Example: You receive $14,400 in SSDI and earn $20,000 in wages. Your combined income is $7,200 plus $20,000, which equals $27,200. This exceeds the $25,000 threshold by $2,200. Half of $2,200 is $1,100. Eighty-five percent of your $14,400 SSDI is $12,240. The lesser of these two is $1,100, so $1,100 of your SSDI is taxable. You pay income tax on that $1,100 at your regular tax rate, not on the full $14,400.

Requesting tax withholding from your SSDI

If you know your SSDI will be taxable, you can ask the Social Security Administration to withhold federal income tax from your monthly payment. This way you do not face a large tax bill when you file your return.

To request withholding, complete Form W-4V (Voluntary Withholding Request) and mail it to your local Social Security office or bring it in person. You can specify a flat dollar amount to withhold each month, or you can request that a percentage be withheld. Social Security will begin withholding the following month.

You can change or stop withholding at any time by submitting a new Form W-4V. If you over-withhold, you will receive the excess as a refund when you file your tax return.

Filing your tax return when you receive SSDI

You must file a federal income tax return if your combined income exceeds certain thresholds. For 2024, a single person with SSDI must file if their combined income is more than $14,600. A married couple filing jointly must file if their combined income is more than $29,200. These thresholds are different from the $25,000 and $32,000 thresholds used to determine whether SSDI is taxable.

When you file, you report your SSDI on Form 1040 (the main tax return form). You also complete Worksheet A or Worksheet B (included in the Form 1040 instructions) to calculate how much of your SSDI is taxable. The IRS provides these worksheets free on its website and in the printed instructions that come with tax forms.

If you use tax software or work with a tax preparer, they will ask you for your SSDI amount and your other income, and the software or preparer will do the calculation for you.

State income tax on SSDI

Most states do not tax SSDI at all, even if the federal government does. However, a few states—including Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont—tax SSDI under certain conditions. The rules vary by state.

If you live in one of these states, contact your state tax authority or a tax preparer familiar with your state's rules. Some states exempt SSDI if your income is below a certain level, while others tax it the same way the federal government does.

Frequently Asked Questions

Do I have to file a tax return if I only receive SSDI and no other income?

No. If SSDI is your only income and it is below the filing threshold for your filing status, you do not have to file a federal return. For 2024, a single person with only SSDI does not have to file unless their combined income exceeds $14,600. However, filing may benefit you if you paid taxes or are due a refund.

What if I work part-time and receive SSDI—will I lose my benefits?

SSDI has no earnings limit, so you will not lose your benefit because you work. However, your wages will increase your combined income, which may make your SSDI taxable. This is different from Supplemental Security Income (SSI), which does have an earnings limit and a different tax treatment.

Can I reduce my taxable SSDI by making charitable donations?

No. Charitable donations reduce your overall tax bill, but they do not reduce the amount of SSDI that is subject to tax. The calculation of taxable SSDI is fixed by the IRS formula and does not change based on deductions.

If I did not withhold taxes and now owe money, what happens?

You report the tax owed on your return and pay it with your return, or you can pay the IRS directly. If you cannot pay in full, the IRS offers payment plans. Going forward, you can request withholding on Form W-4V to avoid the same situation next year.

Does my spouse's SSDI affect whether my SSDI is taxable?

No. Each person calculates their own combined income separately. Your spouse's SSDI does not count toward your combined income unless you file a joint return and are married filing separately, in which case different rules explore. Consult a tax professional if you are unsure how to file.
