How Disability Checks Are Taxed and What You Owe

Whether Your Disability Check Is Taxed Depends on Your Other Income

Social Security Disability Insurance (SSDI) payments may or may not be taxed. The answer depends entirely on your combined income — not just the disability check itself. If your total income from all sources falls below a certain threshold, you owe no federal tax on your SSDI. If it exceeds that threshold, a portion of your SSDI becomes taxable.

The threshold is calculated using a formula called combined income, which adds your adjusted gross income, nontaxable interest, and half of your SSDI benefit. For 2024, if you file as single and your combined income is under $25,000, none of your SSDI is taxed. If you file as married filing jointly, the threshold is $32,000. These thresholds do not change year to year — they are set by law and have remained the same since 1984.

If your combined income exceeds the first threshold, you may owe tax on up to 50 percent of your SSDI. If it exceeds a second, higher threshold ($34,000 for single filers, $44,000 for married filing jointly), you may owe tax on up to 85 percent of your SSDI. The actual percentage depends on how far above the threshold you are.

Key Takeaways

SSDI is taxed only if your combined income (SSDI plus other income sources) exceeds $25,000 for single filers or $32,000 for married filing jointly.
Combined income includes wages, self-employment income, pensions, interest, dividends, and half of your SSDI benefit itself.
If you are taxed, between 50 and 85 percent of your SSDI becomes subject to federal income tax, depending on how much your combined income exceeds the threshold.
You must file a tax return and report your SSDI to determine whether any is taxable — the Social Security Administration does not calculate this for you.
State taxes on SSDI vary: some states tax it, some do not, and rules differ based on your filing status and income level.

How Combined Income Is Calculated

Combined income is not the same as your total income. The Social Security Administration uses a specific formula. Start with your adjusted gross income (the number from your tax return after deductions like educator expenses or student loan interest). Add any nontaxable interest you received. Then add half of your SSDI benefit for the year.

Example: You received $15,000 in SSDI for the year and earned $12,000 from part-time work. You had $200 in nontaxable interest from a municipal bond. Your combined income is $12,000 + $200 + ($15,000 ÷ 2) = $19,700. Since $19,700 is below $25,000, none of your SSDI is taxed.

Other income that counts toward combined income includes wages, self-employment income, rental income, capital gains, taxable pensions, taxable IRA distributions, and taxable annuities. Income that does not count includes Supplemental Security Income (SSI), workers' compensation, veterans' benefits, and certain railroad retirement benefits.

The Two Tax Thresholds and How Much SSDI Becomes Taxable

The federal tax code sets two thresholds. The first threshold is $25,000 for single filers and $32,000 for married filing jointly. If your combined income exceeds this threshold, you calculate how much SSDI is taxable using a formula: take the lesser of (1) half of the amount over the threshold, or (2) half of your total SSDI for the year. That amount is taxable.

The second threshold is $34,000 for single filers and $44,000 for married filing jointly. If your combined income exceeds this higher threshold, you use a different formula. You calculate tax on the amount between the first and second threshold (using the formula above), then add tax on 85 percent of the amount over the second threshold. The result is the total SSDI that becomes taxable, capped at 85 percent of your total SSDI.

Example: You are single, received $20,000 in SSDI, earned $18,000 in wages, and had no other income. Your combined income is $18,000 + ($20,000 ÷ 2) = $28,000. This exceeds the first threshold of $25,000 by $3,000. The lesser of (1) half of $3,000 = $1,500, or (2) half of $20,000 = $10,000 is $1,500. So $1,500 of your SSDI is taxable.

Filing Your Tax Return When You Receive SSDI

You must file a federal tax return if your combined income exceeds the first threshold, even if you owe no income tax. The Social Security Administration sends you a Form SSA-1099-Soc Sec in January showing how much SSDI you received the previous year. You report this amount on your tax return.

Report your SSDI on line 5b of Form 1040 (the main federal income tax form). On line 5a, you report the full amount from your SSA-1099. On line 5b, you report only the taxable portion. If you use tax software or a tax preparer, they will ask you for the SSA-1099 and calculate the taxable amount for you.

You must file even if you think none of your SSDI is taxable, because the IRS uses your return to verify the calculation. If you do not file and you should have, you may face penalties and interest.

State Taxes on SSDI

Thirteen states tax SSDI: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The rules vary by state. Some states use the same federal thresholds. Others have different thresholds or tax SSDI differently than the federal government does.

Colorado, Kansas, and Missouri do not tax SSDI at all if you are over 59½. Connecticut, Minnesota, and Vermont have income thresholds lower than the federal thresholds. New Mexico taxes SSDI only if your federal adjusted gross income exceeds a certain amount, regardless of combined income.

If you live in a state that taxes SSDI, you will need to file a state tax return and report your SSDI there as well. Contact your state tax authority or a tax preparer familiar with your state's rules to understand your specific situation.

What Happens If You Owe Tax on SSDI

If you owe federal income tax on your SSDI, you pay it like any other income tax — either by paying when you file your return, or by making estimated quarterly tax payments during the year if you expect to owe more than $1,000.

The Social Security Administration does not withhold taxes from your SSDI check automatically. If you want taxes withheld, you can request it using Form W-4V (Voluntary Withholding Request). You can choose to have 7, 10, 12, or 22 percent of your SSDI withheld each month. This reduces the amount you receive but also reduces what you owe at tax time.

You can change your withholding request at any time by submitting a new Form W-4V to your local Social Security office or by calling 1-800-772-1213.

Frequently Asked Questions

Does my SSDI count as income for other benefits?

SSDI counts as income for some programs and not others. It counts toward Medicaid and SNAP (food information) in most states, which may reduce your benefits. It does not count toward Supplemental Security Income (SSI). Check with each program you receive to understand how SSDI affects your benefits.

What if I work part-time while receiving SSDI?

Your wages count toward combined income for tax purposes. If your wages plus half your SSDI exceed the first threshold, part of your SSDI becomes taxable. Additionally, SSDI has its own work rules: if you earn over a certain amount (called substantial gainful activity), your SSDI may stop. These are separate rules from taxation.

Can I reduce my taxes by not cashing my SSDI check?

No. You are taxed on SSDI you receive, not on SSDI you cash. If you do not cash the check, you still owe tax on it. The only way to reduce tax on SSDI is to reduce your other income or request withholding from your check.

Do I have to file a tax return if I only receive SSDI?

If SSDI is your only income and it is below the first threshold ($25,000 for single filers), you do not have to file a federal tax return. However, you may want to file anyway if you are due a refund from taxes withheld or if you may have access to for the Earned Income Tax Credit.

What if I disagree with how much SSDI is taxable?

Double-check your combined income calculation using the formula above. If you believe an error was made, contact the IRS at 1-800-829-1040 or work with a tax preparer or tax attorney. The Social Security Administration does not make the tax information — the IRS does based on your tax return.
