Whether you report SSDI depends on your total income and filing status

You may have to report Social Security Disability Insurance (SSDI) on your federal tax return, but only if your combined income exceeds a certain threshold. The IRS calls this combined income "provisional income," and it includes your SSDI payments plus other money you earned or received that year. If your provisional income stays below the threshold for your filing status, you do not report the SSDI at all.

The threshold changes each year and depends on whether you file as single, married filing jointly, or another status. For 2024, the threshold for single filers is $25,000; for married filing jointly, it is $32,000. These numbers are set by federal law and do not change based on your state.

If you do cross the threshold, you do not report all of your SSDI—only a portion of it. The IRS uses a formula to calculate how much counts as taxable income. In most cases, you will report between 0 and 85 percent of your SSDI payments, depending on how far above the threshold your income goes.

Key Takeaways

  • You only report SSDI on your tax return if your provisional income (SSDI plus other income) exceeds $25,000 for single filers or $32,000 for married filing jointly in 2024.
  • Provisional income includes SSDI, wages, self-employment income, interest, dividends, and certain other sources—but not Supplemental Security Income (SSI).
  • If you do cross the threshold, the IRS uses a two-step formula to determine what portion of your SSDI counts as taxable income, not a flat percentage.
  • You will receive a Social Security Benefit Statement (Form SSA-1099) by January 31 each year, which shows your total SSDI for that year and is required to complete your tax return.

How the IRS calculates provisional income

Provisional income is not the same as your total income. It is a specific calculation the IRS uses to determine whether SSDI becomes taxable. To find your provisional income, you add your adjusted gross income (AGI) plus tax-exempt interest plus half of your SSDI payments.

For example: if you earned $20,000 in wages, received $15,000 in SSDI, and had $500 in tax-exempt interest, your provisional income would be $20,000 + $500 + ($15,000 ÷ 2) = $27,500. For a single filer in 2024, this exceeds the $25,000 threshold by $2,500, so some of your SSDI becomes taxable.

The key point is that half your SSDI counts toward the threshold calculation even if none of it ends up being taxable. This is why someone with modest wages and SSDI can still cross the threshold and owe tax on a portion of their benefits.

The two-tier formula for taxable SSDI

If your provisional income exceeds the threshold, the IRS does not straightforward tax all the excess. Instead, it uses a two-step formula that limits how much SSDI can be taxed. The formula is complex, but the outcome is predictable: you will never pay tax on more than 85 percent of your SSDI in any year.

In the first tier, up to 50 percent of the amount you exceed the threshold becomes taxable SSDI. In the second tier, if you exceed a higher threshold (set by law), up to an additional 35 percent of your SSDI becomes taxable. The two tiers combined cap the taxable portion at 85 percent.

Because the formula is mathematical and depends on your specific income, the easiest way to know what you owe is to use IRS Publication 915 (Social Security and Equivalent Railroad Retirement Benefits) or to have a tax preparer calculate it for you. Many tax software programs also include this calculation.

What counts as income for this calculation

Provisional income includes wages, self-employment income, interest (taxable and tax-exempt), dividends, capital gains, rental income, and distributions from retirement accounts. It also includes certain pension income and distributions from IRAs.

Importantly, Supplemental Security Income (SSI) does not count toward provisional income. SSI is a separate program from SSDI, and SSI payments are never taxable. If you receive both SSDI and SSI, only the SSDI portion matters for this calculation.

Earned income from work—whether W-2 wages or self-employment income—counts fully toward provisional income. This is why someone who returns to work while on SSDI may suddenly owe tax on their benefits even if they did not before.

Form SSA-1099 and what to do with it

Every January, the Social Security Administration sends you a Form SSA-1099 (Social Security Benefit Statement) showing the total SSDI you received in the previous year. This form goes to you and to the IRS. You need this form to complete your tax return accurately.

The form shows your SSDI in Box 5. If you received benefits for only part of the year, the form will show only what you actually received. Keep this form with your tax records and use the amount in Box 5 when you calculate your provisional income.

If you do not receive a Form SSA-1099 by early February, contact Social Security at 1-800-772-1213 to request a replacement. You cannot file your return without knowing your total SSDI for the year.

When you might not have to file at all

Even if you received SSDI, you may not be required to file a federal tax return. The IRS sets a minimum income threshold for filing, and it is separate from the SSDI threshold. If your total income (including SSDI) falls below the filing requirement for your age and status, you do not have to file.

For 2024, a single person under 65 with only SSDI income does not have to file unless their income exceeds $14,600. However, if you have other income (wages, interest, self-employment), the threshold is lower. Check IRS Publication 17 or use the IRS Interactive Tax Assistant to determine whether you must file.

Even if you are not required to file, you may want to file anyway if you paid taxes through withholding or if you are due a refund. SSDI payments do not have taxes withheld automatically, but if you have other income that does, you might be may have access to to a refund.

Requesting voluntary withholding on SSDI

If you know your SSDI will be taxable and you want to avoid a large tax bill at filing time, you can ask Social Security to withhold federal income tax from your monthly SSDI payment. This is voluntary—Social Security does not withhold automatically.

To request withholding, complete Form W-4V (Voluntary Withholding Request) and send it to your local Social Security office or mail it to Social Security. You can choose to withhold 7, 10, 15, or 25 percent of your monthly benefit. Once you request it, the withholding continues until you ask Social Security to stop.

Withholding does not change whether you owe tax; it just spreads the payment across the year instead of requiring a lump sum at tax time. If you withhold too much, you will get a refund when you file. If you withhold too little, you will owe when you file.

Frequently Asked Questions

Do I have to report SSI on my taxes?

No. Supplemental Security Income (SSI) is never taxable, and you do not report it on your federal tax return. Only SSDI is potentially taxable. If you receive both programs, only the SSDI portion matters for tax purposes.

What if I earned money from work while on SSDI?

Wages from work count toward your provisional income and may push you over the threshold, making your SSDI taxable. Work incentive programs like Impairment Related Work Expenses (IRWE) can reduce your countable earnings for SSDI purposes, but they do not reduce the income that counts for tax calculations. Report all wages on your tax return.

Can I deduct medical expenses related to my disability?

You can deduct unreimbursed medical expenses if they exceed 7.5 percent of your adjusted gross income for 2024. This includes costs for disability-related care, equipment, and treatment. Keep receipts and consult a tax preparer to see whether your expenses meet the threshold.

What happens if I do not report SSDI when I should have?

The IRS may assess penalties and interest on the unpaid tax. If the error was unintentional, you can file an amended return (Form 1040-X) to correct it. Contact a tax professional or the IRS if you realize you missed reporting SSDI in a prior year.

Does my state tax SSDI differently than the federal government?

Most states do not tax SSDI at all. However, a few states (including Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont) tax SSDI under certain circumstances. Check your state's tax authority website or ask a tax preparer whether your state taxes SSDI.
