Disability income is taxable or tax-free depending on which program pays you and your total household income

Whether you owe federal income tax on disability payments depends on two things: which program is sending you the money, and how much total income you have. Social Security Disability Insurance (SSDI) may be taxable. Supplemental Security Income (SSI) is never taxable. Veterans' disability payments are tax-free. Workers' compensation is tax-free. The threshold that determines whether SSDI is taxable is your "combined income," which includes your wages, interest, half your SSDI, and other sources added together.

If your combined income is below a certain amount, you owe no federal tax on your SSDI. If it exceeds that threshold, you may owe tax on up to 85 percent of your SSDI benefits. The IRS publishes the exact thresholds each year, and they differ based on whether you file as single or married filing jointly.

Key Takeaways

  • SSI payments are never subject to federal income tax, no matter how much other income you have.
  • SSDI becomes taxable only if your combined income (wages plus half your SSDI plus other income) exceeds the IRS threshold for your filing status.
  • The IRS threshold changes each year and is higher for married couples filing jointly than for single filers.
  • You can request that the Social Security Administration withhold taxes from your SSDI payment each month to avoid a large bill at tax time.

How the IRS calculates whether your SSDI is taxable

The IRS uses a formula called combined income to decide if any of your SSDI is taxable. Combined income includes: your adjusted gross income from wages and self-employment, your nontaxable interest, half of your SSDI benefit, and certain other income sources. You add all of these together.

Once you have your combined income total, you compare it to the IRS threshold. For 2024, the threshold is $25,000 if you file as single, head of household, or may have access to widow(er). It is $32,000 if you file as married filing jointly. If your combined income is below the threshold, you owe no tax on your SSDI. If it is above the threshold, the IRS may tax up to 85 percent of your benefits.

The calculation is complex because the amount of SSDI that becomes taxable depends on how far above the threshold you are. The IRS worksheet in Publication 915 walks through the exact steps. Many people find it easier to work with a tax preparer who has experience with SSDI.

Why SSI is never taxable

Supplemental Security Income (SSI) is a needs-based program for people with low income and limited resources. Because SSI is a welfare benefit rather than an earned benefit, the IRS treats it differently from SSDI. SSI payments are never subject to federal income tax, regardless of your other income or how much SSI you receive.

This is one of the clearest differences between the two programs. If you receive SSI, you do not need to report it on your federal tax return, and it does not count toward the combined income threshold that would make other benefits taxable.

Requesting tax withholding from your SSDI payment

If you know that some of your SSDI will be taxable, you can ask the Social Security Administration to withhold federal income tax from your monthly payment. This way you pay tax gradually throughout the year instead of facing a large bill when you file your return.

To request withholding, you fill out Form W-4V and send it to your local Social Security office or mail it to the address on the form. You can choose to have 7, 10, 12, or 22 percent of your benefit withheld each month. If your circumstances change during the year, you can submit a new W-4V to adjust the withholding amount.

Withholding is optional. Some people prefer to pay the tax in one lump sum at tax time, or to make quarterly estimated tax payments. The choice depends on your situation and what works best for your budget.

Other disability income sources and their tax treatment

Veterans' disability compensation paid by the Department of Veterans Affairs is never taxable, even if you have high income from other sources. The same is true for workers' compensation benefits you receive for a work-related injury or illness.

Private disability insurance benefits are usually not taxable if you paid the premiums with after-tax dollars. However, if your employer paid the premiums and you did not report them as income, the benefits may be taxable. Check your policy or ask your employer which premiums were paid with pre-tax money.

Long-term disability (LTD) through an employer is taxable if the employer paid the premiums. It is not taxable if you paid the premiums yourself with after-tax money. Again, your employer's benefits office can tell you which applies to your plan.

What to do if you receive a notice from the IRS

If the IRS sends you a notice saying you owe tax on your SSDI, do not ignore it. The notice will explain what income the IRS counted and how they calculated the tax. Read it carefully to make sure the income figures are correct.

If the figures are wrong—for example, if the IRS shows SSDI income you did not actually receive, or if they miscalculated your wages—you can respond to the notice with documentation. If you disagree with the calculation but the figures are correct, you may want to consult a tax professional or contact the IRS directly to discuss your situation.

If you cannot pay the tax bill in full, the IRS offers payment plans and other options. You can also request an installment agreement so you pay over time rather than in one lump sum.

Reporting SSDI on your tax return

Even if none of your SSDI is taxable, you must still report it on your federal tax return. You will receive a Form SSA-1099 from Social Security showing the total SSDI you received during the year. You report this amount on your return, and then use the IRS worksheet to calculate whether any of it is taxable.

If you file electronically, tax software will usually walk you through the combined income calculation. If you file by paper, use IRS Publication 915 or work with a tax preparer. The key is to report the full amount of SSDI you received, even if the final taxable amount is zero.

Frequently Asked Questions

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

Not necessarily. If SSDI is your only income and it is below the standard deduction for your filing status, you do not have to file. However, if you have other income—wages, interest, self-employment income—you may need to file even if your SSDI is not taxable. The IRS has a worksheet to help you determine whether you must file.

What if I receive both SSDI and SSI?

SSI is never taxable. Only the SSDI portion may be taxable, based on your combined income. When calculating combined income, you include the SSDI but not the SSI. Your tax preparer or the IRS worksheet will show you how to separate the two.

Can I deduct medical expenses related to my disability?

Yes, if your medical expenses are high enough. You can deduct medical and dental expenses that exceed 7.5 percent of your adjusted gross income. This includes doctor visits, prescriptions, therapy, and equipment related to your disability. Keep receipts and ask a tax preparer whether your expenses meet the threshold.

What happens if Social Security overpays me and I have to repay it?

If you repay SSDI benefits, you may be able to deduct the repayment from your taxable income in the year you repay it. This is called a Section 1040(a) adjustment. The rules are complex, so discuss this with a tax preparer if you are repaying a significant amount.

Will my SSDI affect my spouse's taxes?

Your SSDI does not directly affect your spouse's tax liability. However, if you file jointly, your combined income (including your spouse's income and half your SSDI) determines whether your SSDI is taxable. Your spouse's income counts toward that threshold even if they do not receive SSDI themselves.
