Whether You Owe Taxes on Disability Depends on Your Total Income

You may owe federal income tax on your SSDI benefits, but you may not — it depends on how much other income you have. SSI (Supplemental Security Income) is almost never taxable. The rule is this: if your "combined income" exceeds a certain threshold, you have to count part of your benefits as taxable income on your federal return.

Combined income is not just your SSDI payment. It includes wages, interest, dividends, pensions, and other income, plus half of your SSDI benefits. The threshold is $25,000 if you file single, or $32,000 if you file married filing jointly. If you are married filing separately, the threshold is $0 — meaning any SSDI at all may be taxable.

The IRS does not automatically withhold taxes from SSDI payments the way an employer does from paychecks. You have to calculate what you owe and either pay it when you file your return, or request that the Social Security Administration withhold a flat amount from each monthly payment.

Key Takeaways

  • SSDI becomes taxable only if your combined income (SSDI plus other income) exceeds $25,000 single or $32,000 married filing jointly.
  • SSI payments are almost never taxable, even if you have other income.
  • You can ask Social Security to withhold taxes from your SSDI payment each month, or pay the full amount when you file your return.
  • If you have little or no other income, your SSDI is likely not taxable at all.
  • You must file a return and report your SSDI even if none of it is taxable, if your income is above the filing threshold for your age and filing status.

How the IRS Calculates Taxable SSDI

The calculation has two steps. First, add up your combined income: all your non-SSDI income plus half your SSDI benefits. If that total is below the threshold for your filing status, you owe no tax on your benefits.

If combined income exceeds the threshold, the IRS taxes either 50% or 85% of your SSDI, depending on how far over the threshold you are. The exact formula is complex, but the result is that you never pay tax on more than 85% of your benefits, even if your other income is very high.

Example: You are single and receive $1,500 per month in SSDI ($18,000 per year). You have no other income. Your combined income is $18,000 plus half of $18,000 = $27,000. This exceeds the $25,000 threshold by $2,000. You would owe tax on 50% of the amount over the threshold, which is $1,000 of your SSDI. The rest remains tax-free.

SSI Is Almost Never Taxable

Supplemental Security Income (SSI) is a needs-based program for people with low income and few resources. SSI payments themselves are not taxable income under federal law, period. You do not count them toward the combined income threshold, and you do not report them as income on your tax return.

However, if you have other income — wages, interest, a pension — that other income is still taxable and still counts toward your filing requirement. You may have to file a return even though your SSI is not taxable.

Requesting Tax Withholding From Your SSDI Payment

If you know you will owe taxes, you can ask Social Security to withhold a fixed amount from your SSDI each month. This reduces your monthly payment but means you will not owe a large bill when you file your return.

To request withholding, fill out Form W-4V (Voluntary Withholding Request) and mail it to your local Social Security office, or bring it in person. You can also request withholding by calling Social Security at 1-800-772-1213. You choose the dollar amount withheld — it does not have to match what you actually owe, and you can change it anytime.

Withholding is voluntary. If you do not request it, Social Security will not withhold anything, and you will owe the full tax when you file your return.

When You Must File a Tax Return

You must file a federal income tax return if your gross income is above the filing threshold for your age and filing status. For 2024, the threshold is $14,600 for a single person under 65, and $18,150 for a single person 65 or older. These thresholds increase slightly each year.

You must file even if none of your SSDI is taxable, as long as your total income (including half your SSDI) exceeds the threshold. The IRS uses your filing return to verify that you reported all your income correctly.

If your income is below the filing threshold, you do not have to file a return. However, if you had taxes withheld from your SSDI or other income, you may want to file anyway to get a refund.

What Happens If You Do Not File or Pay Taxes Owed

If you owe taxes and do not file a return, the IRS will eventually send you a notice. If you do not respond, they can assess a penalty and interest on the unpaid tax. The penalty is usually 5% per month of the unpaid amount, up to 25%.

If you cannot pay the full amount, you can set up a payment plan with the IRS. Call 1-800-829-1040 or visit irs.gov to discuss options. The IRS is often willing to work with people on fixed incomes, and setting up a plan stops the penalty from growing.

If you are behind on taxes from prior years, the IRS may offset your SSDI payment — meaning they will take part of your monthly benefit to pay the debt. You have the right to request a hearing before this happens.

State Income Tax on SSDI

Most states do not tax SSDI benefits. 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 total income is below a certain level, or if you are over a certain age. Do not assume your state follows the federal rule.

Frequently Asked Questions

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

Only if your combined income (SSDI plus half your SSDI) exceeds the filing threshold for your age and status. For most people receiving only SSDI, this means you do not have to file. However, if you had taxes withheld, you may want to file to get a refund.

Can I get a refund if I had too much tax withheld from my SSDI?

Yes. If you requested withholding and it turns out you did not owe that much tax, you will get a refund when you file your return. You can also adjust your withholding amount anytime by submitting a new Form W-4V to Social Security.

What if I have both SSDI and SSI?

Your SSI is never taxable. Your SSDI may be taxable depending on your combined income. When calculating combined income, you count your SSDI but not your SSI. The threshold remains $25,000 single or $32,000 married filing jointly.

Does receiving SSDI affect my tax credits or deductions?

SSDI does not directly affect most credits or deductions. However, your total income (including half your SSDI) may affect whether you can claim certain credits like the Earned Income Tax Credit. A tax preparer can review your specific situation.

Who do I contact if I disagree with how much of my SSDI is taxable?

Contact the IRS directly at 1-800-829-1040 or visit irs.gov. You can also work with a tax preparer or tax attorney. The IRS Publication 915 explains the calculation in detail and includes a worksheet to verify the amount.
