Whether you owe federal income tax on your SSDI depends on your total income and filing status
The Social Security Administration does not automatically withhold federal income tax from SSDI payments. Whether you owe tax on those payments depends on how much other income you have—not just SSDI, but wages, interest, pensions, and other sources combined. If your total income stays below a certain threshold, you owe nothing. If it crosses that threshold, a portion of your SSDI becomes taxable.
The threshold is called your combined income, and it is calculated differently depending on whether you file as single, married filing jointly, or another status. The IRS publishes these thresholds each year, and they do not change often. Understanding where you stand requires adding up all your income sources, then comparing that total to the threshold for your filing status.
Key Takeaways
- SSDI is taxable only if your combined income (SSDI plus all other income) exceeds a threshold that depends on your filing status.
- Combined income is calculated as adjusted gross income plus nontaxable interest plus half of your SSDI benefits.
- If you are single and your combined income is under $25,000, you owe no federal tax on SSDI; if married filing jointly, the threshold is $32,000.
- Up to 85 percent of your SSDI can become taxable if your combined income is high enough, but most people with SSDI alone do not reach that level.
- You must file a tax return to report SSDI if your combined income exceeds the threshold for your filing status, even if no tax is owed.
How the IRS calculates combined income for SSDI
The IRS does not straightforward add up your SSDI and other income. Instead, it uses a formula called combined income, which is: your adjusted gross income (AGI) plus any nontaxable interest plus half of your SSDI benefits for the year.
Start by listing all income sources: W-2 wages, self-employment income, interest, dividends, pensions, rental income, and any other money you received. Subtract deductions you are allowed to take (such as educator expenses or student loan interest). That gives you your adjusted gross income. Then add back any tax-exempt interest (such as from municipal bonds) and add half of your annual SSDI. That total is your combined income.
Example: You received $15,000 in SSDI and $8,000 in part-time wages. Your adjusted gross income is $8,000. You have no nontaxable interest. Combined income = $8,000 + $0 + ($15,000 ÷ 2) = $15,500. For a single filer, the threshold is $25,000, so you would owe no tax on SSDI.
Income thresholds by filing status
The IRS sets two thresholds for each filing status. The first threshold determines whether any SSDI is taxable. The second, higher threshold determines whether the maximum amount (85 percent) of SSDI can be taxed. Most people with SSDI do not reach the second threshold.
| Filing Status | First Threshold (Any SSDI Taxable) | Second Threshold (Up to 85% Taxable) |
|---|---|---|
| Single | $25,000 | $34,000 |
| Married Filing Jointly | $32,000 | $44,000 |
| Married Filing Separately | $0 | $0 |
If you are married and file separately, a different rule applies: if you lived with your spouse at any time during the year, all of your SSDI is taxable. This is a strong incentive to file jointly if you are married and receiving SSDI.
These thresholds have remained the same since 1984 and are not adjusted for inflation each year. That means more people reach them over time as wages and other income sources grow.
How much of your SSDI becomes taxable
If your combined income exceeds the first threshold, the amount of SSDI that becomes taxable is calculated using a two-step formula. The calculation is complex, but the result is never more than 85 percent of your SSDI benefits.
For most people whose combined income is between the first and second threshold, the taxable portion is the lesser of: (1) half of the amount by which combined income exceeds the first threshold, or (2) half of your SSDI. Once combined income exceeds the second threshold, up to 85 percent of SSDI can be taxed, but the calculation still follows IRS rules and is not straightforward 85 percent of all benefits.
Because the formula is intricate, the IRS Worksheet for calculating taxable SSDI is included in Publication 915, which you can read from irs.gov. Many tax software programs also calculate this automatically if you enter your SSDI amount and other income.
Reporting SSDI on your tax return
SSDI is reported on Form 1040 (the main federal income tax return) on the line for Social Security benefits. You will receive a Form SSA-1099 from the Social Security Administration each January, showing the total SSDI you received in the prior year. Use this form to fill in the SSDI line on your return.
If you must file a return because your combined income exceeds the threshold for your filing status, you will also need to complete Worksheet 1 or Worksheet 2 in IRS Publication 915 to calculate how much of your SSDI is taxable. The worksheet asks you to enter your combined income, your filing status, and your SSDI amount, then walks you through the calculation step by step.
You must file a return to report SSDI even if the calculation shows you owe zero tax. Filing is required whenever your combined income exceeds the threshold, regardless of whether tax is actually due. Failing to file when required can result in penalties and interest.
State income tax on SSDI
Federal income tax and state income tax are separate. Some states do not tax SSDI at all. Others follow the federal rule and tax SSDI only if combined income exceeds a threshold. A few states tax SSDI more broadly. You must check your state's rules separately.
States that do not tax SSDI include California, Florida, Illinois, Louisiana, Mississippi, New York, Ohio, Pennsylvania, and Texas. If you live in one of these states, you do not owe state income tax on SSDI, though you may owe state tax on other income such as wages or pensions.
States that follow the federal rule (taxing SSDI only above a threshold) include Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont. Contact your state tax authority or check its website to learn the exact threshold for your state, as it may differ from the federal threshold.
What to do if you receive a notice from the IRS
If the IRS sends you a notice about SSDI and taxes, it usually means one of three things: you did not file a return when you should have, you reported SSDI incorrectly, or the IRS is asking you to verify information. Do not ignore the notice.
Read the notice carefully to understand what the IRS is asking. If you did not file because you thought you did not owe tax, but your combined income was actually above the threshold, you may need to file a return for that year. If you filed but made an error, you can file an amended return (Form 1040-X) to correct it. If the IRS is asking for documentation, gather your Form SSA-1099 and records of other income and respond within the important date stated in the notice.
If you are unsure how to respond, you can contact the IRS at 1-800-829-1040 or visit irs.gov. The IRS also offers free tax preparation help through the Volunteer Income Tax information (VITA) program if your income is below a certain level.
Frequently Asked Questions
Do I have to pay tax on SSDI if it is my only income?
No. If SSDI is your only income, your combined income equals half of your SSDI. For a single person, that would have to exceed $25,000, which means your SSDI would have to be over $50,000 per year. Most people receiving SSDI do not receive that much, so SSDI alone does not trigger a tax obligation.
What if I have wages and SSDI—do I have to file?
It depends on the total. Add your wages, half your SSDI, and any other income. If that sum exceeds the threshold for your filing status, you must file. If you earned $10,000 in wages and received $15,000 in SSDI, your combined income is $17,500, which is below the $25,000 threshold for single filers, so you would not have to file.
Can I have taxes withheld from my SSDI to avoid owing at tax time?
Yes. You can request that the Social Security Administration withhold federal income tax from your SSDI payments. Complete Form W-4V and submit 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 25 percent of your benefit. This does not change whether SSDI is taxable; it just spreads the tax payment across the year instead of owing it all at tax time.
Does SSDI count as income for other programs like Medicaid or food information?
SSDI is counted as income for most means-tested programs, but the rules vary by program and state. For Supplemental Security Income (SSI), SSDI is counted but with exclusions. For Medicaid, it depends on your state. For SNAP (food information), SSDI is counted as income. Contact the specific program to learn how your SSDI affects your status.
What if I disagree with the amount of SSDI shown on my Form SSA-1099?
Contact the Social Security Administration directly. You can call 1-800-772-1213 or visit your local Social Security office. Bring your Form SSA-1099 and any records of SSDI payments you received. The SSA can verify the amount and issue a corrected form if needed. Do not file your tax return until the amount is confirmed.
