Social Security Disability benefits may be taxable, depending on your total income and filing status

Whether you owe federal income tax on your Social Security Disability Insurance (SSDI) payments depends on your combined income — not just what you receive from Social Security. The IRS uses a formula that includes your adjusted gross income, nontaxable interest, and half of your Social Security benefits. If that combined total exceeds a certain threshold, a portion of your benefits becomes taxable.

The thresholds are fixed and do not change with inflation. For 2024, if you file as single and your combined income exceeds $25,000, some of your benefits are taxable. If you file as married filing jointly, the threshold is $32,000. These numbers have stayed the same since 1984, which means more people cross them each year as wages and other income rise.

The taxable portion is never more than 85 percent of your benefits, even if your income is very high. For most people, the actual amount taxed is much less — often 50 percent or less of the excess over the threshold.

Key Takeaways

  • Your SSDI benefits are taxable only if your combined income (wages, interest, half your benefits, and other sources) exceeds $25,000 for single filers or $32,000 for married filing jointly.
  • Combined income includes wages you earn, interest and dividends, income from a spouse, and half of your Social Security benefits — not the full amount.
  • If you are below the threshold, you owe no federal tax on your SSDI, even if you have other income.
  • You can request that the Social Security Administration withhold federal income tax from your monthly benefit payment to avoid a tax bill at the end of the year.

How the IRS calculates whether your benefits are taxable

The IRS uses a two-step calculation. First, you add up your combined income: your adjusted gross income (wages, self-employment income, taxable pensions, and taxable interest), plus nontaxable interest (such as interest from municipal bonds), plus half of your Social Security benefits.

Next, you compare that total to your threshold. If it is below $25,000 (single) or $32,000 (married filing jointly), you owe no tax on your benefits. If it exceeds the threshold, the IRS taxes the lesser of two amounts: either 50 percent of the excess over the threshold, or 50 percent of your benefits themselves. For higher incomes, an additional 85 percent tier applies, but most people do not reach it.

Example: You are single and receive $1,500 per month in SSDI ($18,000 per year). You also earn $10,000 from part-time work. Your combined income is $10,000 + $0 (nontaxable interest) + $9,000 (half your benefits) = $19,000. This is below $25,000, so none of your benefits are taxable, even though you have earned income.

Another example: You are single, receive $18,000 in SSDI, and have $8,000 in taxable interest from savings. Your combined income is $8,000 + $0 + $9,000 = $17,000. Still below the threshold, so no tax owed.

What counts toward your combined income

Combined income includes more than just wages. It includes:

  • Wages and self-employment income
  • Taxable interest and dividends
  • Capital gains
  • Taxable pensions and annuities
  • Rental income
  • Income from a spouse (if filing jointly)
  • Half of your Social Security benefits

It does not include Supplemental Security Income (SSI), workers' compensation, or certain other benefits. Nontaxable interest — such as interest from municipal bonds — counts toward combined income even though it is not taxable itself.

If you are married and file jointly, your spouse's income counts too, even if your spouse does not receive Social Security. This can push a couple over the threshold even if each person individually would be under it.

Requesting tax withholding from your SSDI payment

If you expect your benefits to be taxable, you can ask Social Security to withhold federal income tax directly from your monthly payment. This prevents a large tax bill when you file your return.

To set up withholding, complete Form W-4V (Voluntary Withholding Request) and send it to your local Social Security office or mail it to the address on the form. You can choose to withhold 7, 10, 15, or 22 percent of your benefit payment. Social Security will begin withholding the following month.

You can change or stop withholding at any time by submitting a new Form W-4V. If you want to check whether withholding is already in place, call Social Security at 1-800-772-1213 or log into your account at ssa.gov.

Filing your tax return when you receive SSDI

You must file a federal income tax return if your combined income exceeds the threshold for your filing status, even if no tax is actually owed. Social Security sends you a Form SSA-1099 each January showing the total benefits you received the previous year.

When you file, you report your Social Security benefits on Schedule 1 (Form 1040). The IRS worksheet in the instructions to Form 1040 walks you through the calculation of how much, if any, is taxable. Many tax software programs calculate this automatically if you enter your benefit amount.

If you did not have tax withheld and you owe tax on your benefits, you can pay it when you file or set up a payment plan with the IRS. If you had too much withheld, you will receive a refund.

State income tax on SSDI

Federal tax rules do not explore to state income tax. Most states do not tax Social Security benefits at all, but a few do. The states that tax SSDI are Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont. Each state has its own income thresholds and rules.

If you live in one of these states, contact your state tax authority or a tax professional to understand your state tax obligations. Some states offer exemptions or deductions for disability income that may reduce or eliminate your state tax liability.

What to do if you cannot pay taxes owed on your benefits

If you receive a tax bill and cannot pay it in full, you have options. You can file your return on time and pay as much as you can, then contact the IRS to set up a payment plan. The IRS offers short-term plans (120 days or less) at no cost and long-term installment agreements for a small setup fee.

You can also request an extension to file your return (not to pay), though interest and penalties will accrue on any unpaid tax. If you are experiencing financial hardship, the IRS has programs to temporarily delay collection or reduce penalties.

Call the IRS at 1-800-829-1040 to discuss your situation, or work with a tax professional or free tax clinic. The IRS Free File program offers free tax preparation for people with income below a certain level, and many community organizations offer free tax help to seniors and people with disabilities.

Frequently Asked Questions

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

No, not unless your combined income exceeds the threshold. If SSDI is your only income and it is below $25,000 (single) or $32,000 (married filing jointly), you do not have to file. However, if you had tax withheld, you should file to get a refund.

If I work part-time while receiving SSDI, will my benefits be reduced?

That is a separate question from taxation. SSDI has work incentives and earnings limits that may affect your benefit amount, but those are different from whether your benefits are taxable. You should contact Social Security about work incentives before starting work.

Can I reduce my taxable income by giving money to charity?

Charitable donations do not reduce the combined income calculation used for Social Security taxation. However, if you itemize deductions on your tax return, charitable donations may reduce your overall taxable income. Consult a tax professional about your specific situation.

What if I disagree with the amount of tax the IRS says I owe on my SSDI?

You can file a Form 1040-X (Amended Return) if you believe the calculation is wrong, or you can dispute the assessment with the IRS. The IRS has a dispute process, and you can also request help from the Taxpayer Advocate Service if you believe you have been treated unfairly.

Does receiving SSDI affect my Medicare premiums?

No. Your SSDI benefit amount does not affect your Medicare Part B or Part D premiums. However, your income (including combined income for tax purposes) may affect your premiums if it is very high — that is a separate calculation called Income-Related Monthly Adjustment Amounts (IRMAA).
