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

If SSDI is your only income, you almost certainly owe no federal income tax on it. The Social Security Administration does not withhold taxes from SSDI payments, and most recipients never file a federal tax return because their benefits fall below the threshold where tax is required.

The rule is straightforward: you only owe federal income tax on SSDI if you have other income—wages from work, interest, pensions, or self-employment earnings—that pushes your total above a certain amount. For most people receiving only SSDI, that threshold is never reached.

State taxes are different. A handful of states tax SSDI benefits, though most do not. If you live in one of those states and have other income, you may owe state tax even if you owe nothing federal. The states that tax SSDI are Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont—though even in these states, many recipients pay nothing because of state-level exemptions.

Key Takeaways

  • SSDI is not taxed federally if it is your only income, and the Social Security Administration never withholds taxes from your monthly payment.
  • You owe federal tax on SSDI only if your total income from all sources exceeds a threshold that depends on your filing status and other income.
  • Eleven states tax SSDI benefits, but most people in those states still pay nothing because of state exemptions or low total income.
  • If you work while on SSDI, your wages count as income and may trigger a tax obligation even if your SSDI itself is not taxed.

How the federal tax threshold works

The Social Security Administration uses a formula called "combined income" to decide whether your SSDI is taxable. Combined income includes your SSDI benefit plus half of your SSDI plus any other income you have—wages, interest, pensions, rental income, or anything else.

For a single filer in 2024, if your combined income is under $25,000, none of your SSDI is taxed. If it is between $25,000 and $34,000, up to 50 percent of your benefits may be taxed. If it is over $34,000, up to 85 percent may be taxed. For married couples filing jointly, the thresholds are $32,000 and $44,000.

This means that if you have a part-time job earning $15,000 a year and receive $12,000 in SSDI, your combined income is roughly $18,000 (half of $12,000 plus the $15,000 in wages). You would still be under the $25,000 threshold and would owe no federal tax on either source.

When you do owe tax on SSDI

Tax on SSDI becomes an issue when you have substantial other income. The most common scenario is someone who continues to work while on SSDI, either part-time or full-time. If your wages plus half your SSDI push you over $25,000, the formula kicks in and part of your benefit becomes taxable.

Investment income also counts. If you have interest from savings, dividends from stocks, or rental income, all of it goes into the combined income calculation. Even modest investment income can move you into a taxable range if your SSDI is already substantial.

Pensions and retirement distributions count too. If you receive a pension from a previous job or withdraw money from an IRA, those amounts are included in combined income. Some people are surprised to learn that a small pension can make their SSDI taxable even though the pension itself might not be large enough to trigger tax on its own.

States that tax SSDI benefits

Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont all tax SSDI to some degree. However, most of these states have exemptions that protect low-income recipients.

Connecticut, for example, taxes SSDI only if your total income exceeds $50,000 for a single filer. Minnesota exempts SSDI entirely for most recipients. New Mexico and Rhode Island have income thresholds that exclude many people on SSDI from state tax.

If you live in one of these states, contact your state tax authority or a tax preparer familiar with your state's rules. The exemptions and thresholds vary, and what applies in one state does not explore in another. Some states also offer credits or deductions specifically for SSDI recipients that can reduce or eliminate your state tax obligation.

What happens if you work while on SSDI

Working while on SSDI is allowed, but your wages affect both your tax situation and your benefit amount. For tax purposes, your wages count as income in the combined income formula, which may make part of your SSDI taxable.

Additionally, Social Security has a separate rule called the Substantial Gainful Activity (SGA) limit. In 2024, if you earn more than $1,550 per month (or $2,590 if you are blind), Social Security may consider you no longer disabled and stop your benefits. Below that threshold, you can work and keep your full benefit, though your wages still count toward the tax calculation.

If you are considering work, report your earnings to Social Security promptly. They have work incentive programs—like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS)—that can reduce the income Social Security counts, which may help you keep your benefits and lower your tax burden.

Filing taxes when you receive SSDI

Even if you owe no federal income tax, you may want to file a return. If you had taxes withheld from wages or other income, filing allows you to claim a refund. If you have dependents, you may be able to claim the Child Tax Credit or Earned Income Tax Credit, both of which require filing a return.

Social Security sends Form SSA-1099 in January showing your SSDI benefits for the previous year. You do not need this form to file taxes—it is informational only—but it is useful to have when you sit down to prepare your return or meet with a tax preparer.

If you are unsure whether you need to file, the IRS website has a tool that walks you through the rules based on your age, filing status, and income sources. Many communities also offer free tax preparation through the Volunteer Income Tax information (VITA) program, which serves people with low to moderate income.

Frequently Asked Questions

Do I have to file taxes if SSDI is my only income?

No. If SSDI is your only income and it is below the filing threshold for your age and status, you have no tax obligation and do not need to file. However, if you had taxes withheld from other income during the year, filing a return will get you a refund.

Will Social Security withhold taxes from my monthly payment?

No. Social Security does not withhold federal income tax from SSDI payments. If you owe tax on your benefits, you pay it when you file your return, not from your monthly check.

What if I live in a state that taxes SSDI but my income is very low?

Most states that tax SSDI have exemptions for low-income recipients. Contact your state tax authority or a local tax preparer to find out whether you fall below your state's threshold. Many people in these states owe nothing despite living there.

Does my spouse's income count toward the tax threshold on my SSDI?

Only if you file jointly. If you are married and file a joint return, your spouse's income is included in the combined income calculation. If you file separately, only your income counts toward your threshold.

If I work part-time, will my wages make my SSDI taxable?

Possibly. Your wages count as income in the combined income formula. Whether they push you into a taxable range depends on how much you earn and how much SSDI you receive. Use the formula (half your SSDI plus all other income) to estimate whether you will cross the $25,000 threshold.
