Most people on SSDI pay no federal income tax on their benefits

Whether you owe federal income tax on your SSDI payments depends on your total income for the year, not on the disability payment itself. If SSDI is your only income, you almost certainly owe nothing. If you have other income — wages, interest, rental income, or certain other sources — the IRS counts part of your SSDI as taxable income using a formula that varies by your filing status.

The threshold is high enough that most SSDI recipients never cross it. You only start owing tax if your "combined income" (your adjusted gross income plus half your SSDI payment, plus any tax-exempt interest) exceeds a base amount. For a single filer in 2024, that base is $25,000. For married couples filing jointly, it is $32,000. These thresholds have not changed since 1984, which is why they catch fewer people each year as wages and other income sources rise.

State income tax is a separate question. Some states tax SSDI; most do not. The state where you live, not where you receive the payment, determines this. You should check your state's tax rules or contact your state revenue department to know for certain.

Key Takeaways

  • If SSDI is your only income, you owe no federal income tax on it, regardless of the payment amount.
  • You may owe tax on part of your SSDI only if your combined income (wages, interest, and half your SSDI) exceeds $25,000 (single) or $32,000 (married filing jointly).
  • The IRS uses a two-tier formula: up to 50 percent of your SSDI becomes taxable at the first threshold, and up to 85 percent becomes taxable at the second threshold.
  • State income tax treatment of SSDI varies by state; most states do not tax it, but you should verify your state's rules.
  • The Social Security Administration sends Form SSA-1099 in January showing your annual SSDI payment, which you use to calculate taxable income.

How the IRS calculates taxable SSDI using combined income

The calculation has two tiers. First, the IRS adds up your adjusted gross income, half your SSDI payment, and any tax-exempt interest (such as municipal bond interest). This sum is your "combined income." If it exceeds the base amount for your filing status, some of your SSDI becomes taxable.

At the first tier, up to 50 percent of your SSDI becomes taxable. This applies to the amount by which your combined income exceeds the base. For example, if you are single, your combined income is $28,000, and your SSDI is $12,000, the excess over $25,000 is $3,000. Half of that excess ($1,500) is taxable, but only up to half your annual SSDI payment ($6,000). In this case, $1,500 of your SSDI counts as taxable income.

At the second tier, if your combined income exceeds a higher threshold ($34,000 for single filers, $44,000 for married filing jointly), an additional portion of your SSDI becomes taxable. Up to 85 percent of your SSDI can be taxed under this second tier. Most SSDI recipients never reach this level.

When you receive Form SSA-1099 and how to use it

In January of each year, the Social Security Administration mails Form SSA-1099 to every SSDI recipient. This form shows the total amount of SSDI you received in the previous calendar year. You use this figure to calculate your combined income and determine whether any of your SSDI is taxable.

You do not send Form SSA-1099 to the IRS with your tax return. Instead, you use the amount shown on it to fill out your Form 1040 (the main federal income tax form) or Form 1040-SR (for people 65 and older). If you file electronically, your tax software will ask for this information and calculate the taxable portion automatically.

If you did not receive Form SSA-1099 by early February, contact Social Security at 1-800-772-1213 or visit your local Social Security office. You need the form to file accurately, even if you believe you owe no tax.

State income tax treatment of SSDI varies widely

Most states do not tax SSDI at all. However, some states do include it in taxable income using their own rules, which may differ from federal rules. States that currently tax SSDI include Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont, though state tax laws change and you should verify the current rule.

Even if your state taxes SSDI, the threshold or calculation method may be more generous than the federal formula. Some states exempt SSDI entirely for people over a certain age or with income below a threshold. Contact your state's department of revenue or tax authority to learn the exact rule for your situation.

If you move to a different state during the year, you may owe tax to both states for part of the year. State tax rules for part-year residents vary, so consult a tax professional or your new state's revenue department if you relocate.

What to do if you owe tax on SSDI

If your combined income exceeds the threshold and you owe federal income tax on part of your SSDI, you can pay it in several ways. You can include the tax liability on your annual Form 1040 and pay it when you file. You can also request that Social Security withhold federal income tax directly from your SSDI payment each month, which reduces the amount you receive but ensures you do not owe a large bill at tax time.

To set up withholding, complete Form W-4V (Voluntary Withholding Request) and submit it to Social Security. You can choose to withhold 7, 10, 15, or 25 percent of your monthly payment. This is optional, but many people find it easier than paying a lump sum in April.

If you have not filed taxes in the past and now owe, or if you are unsure whether you owe, the IRS offers free tax preparation services through the Volunteer Income Tax Assistance (VITA) program. VITA sites are located in libraries, community centers, and nonprofits across the country and serve people with low to moderate income. You can find a site near you at irs.gov or by calling 211.

Frequently Asked Questions

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

No. If SSDI is your only income and your combined income is below the threshold ($25,000 for single filers), you have no federal tax filing requirement. However, if you had federal income tax withheld from your SSDI or if you are owed a refundable tax credit (such as the Earned Income Tax Credit), filing a return may result in a refund.

What counts as income for the combined income calculation?

Wages, self-employment income, interest, dividends, rental income, and capital gains all count. Social Security retirement benefits count if you receive them. Supplemental Security Income (SSI) does not count. Tax-exempt interest (such as from municipal bonds) counts for this calculation even though it is not taxable income.

Can I reduce my taxable SSDI by claiming deductions?

Standard deductions and itemized deductions do not reduce the amount of SSDI that becomes taxable. The SSDI taxation formula is separate from the regular deduction process. However, deductions do reduce your overall taxable income, which may lower your total tax bill.

If I work part-time and receive SSDI, how does that affect my taxes?

Your wages count as income in the combined income calculation. This may push you over the threshold and make part of your SSDI taxable. Additionally, if you are under full retirement age and working, Social Security may reduce your SSDI payment itself (not for tax purposes, but as a benefit reduction). Consult Social Security about work incentives and how earnings affect your specific situation.

What if I disagree with the amount shown on Form SSA-1099?

Contact Social Security immediately. Errors on the form are rare but do happen. Social Security can issue a corrected form if the amount is wrong. Keep records of your monthly SSDI deposits to verify the total shown on the form.
