Whether you owe taxes on SSDI depends on your total income
You may owe federal income tax on your Social Security Disability Insurance (SSDI) benefits, but only if your combined income exceeds a certain threshold. The IRS calls this combined income your "provisional income," and it includes your SSDI payments plus other money you receive — wages, interest, dividends, and some other benefits.
The threshold is low: $25,000 for a single filer, or $32,000 for married couples filing jointly. If your provisional income stays below these amounts, you owe no federal tax on your SSDI. If it goes above, you may owe tax on up to 85 percent of your benefits.
State taxes are separate. Some states do not tax SSDI at all. Others tax it the same way the federal government does. A few have their own rules. You need to check your state's tax authority website or ask a tax preparer what your state requires.
Key Takeaways
- You only owe federal tax on SSDI if your combined income (wages, interest, other benefits, and half your SSDI) exceeds $25,000 as a single filer or $32,000 if married filing jointly.
- If you do owe tax, you pay it on up to 85 percent of your benefits, not the full amount.
- State tax rules vary widely — some states do not tax SSDI at all, while others tax it fully or partially.
- The Social Security Administration sends you a Form SSA-1099 each January showing how much you received, which you use to calculate your tax.
How the IRS calculates your provisional income
The IRS does not count all your income the same way. To find your provisional income, start with your adjusted gross income (AGI) — the number from your tax return before deductions. Then add back certain items the IRS subtracted: tax-exempt interest, half of your SSDI benefits, and half of any other Social Security benefits you receive.
That total is your provisional income. If it is below $25,000 (single) or $32,000 (married filing jointly), you stop here — no tax on SSDI. If it is above those thresholds, you move to the next step.
The math gets more complex once you cross the threshold, because the IRS uses a two-tier system. The first tier covers income between the threshold and $9,000 more ($34,000 to $44,000 for married couples). The second tier covers anything above that. Most people pay tax on 50 percent of benefits in the first tier and 85 percent in the second tier, though the exact amount depends on how far over the threshold you go.
What counts as income for this calculation
Wages from a job count. Interest and dividends count. Rental income counts. Pensions count. Self-employment income counts. Half of any Social Security retirement or survivor benefits you receive counts.
Some income does not count: tax-exempt interest (usually from municipal bonds), workers' compensation, Supplemental Security Income (SSI), and certain veterans' benefits. If you are unsure whether a specific payment counts, the Social Security Administration's publication 915 lists the full rules, though a tax preparer can answer faster.
The reason this matters: even a small amount of other income can push you over the threshold and trigger tax on your SSDI. Someone receiving $1,500 a month in SSDI ($18,000 a year) plus $8,000 in part-time wages is already at $26,000 in provisional income and will owe tax on some benefits.
The Form SSA-1099 and how to use it
Each January, the Social Security Administration mails you a Form SSA-1099 showing how much SSDI you received in the previous year. This form goes to you and to the IRS. You use Box 5 (the net SSDI amount) when you file your taxes.
Keep this form with your tax records. If you file electronically, your tax software will ask for the amount from Box 5. If you file by hand, you enter it on your Form 1040 or 1040-SR. Do not ignore the form or assume you do not need to report it — the IRS already has a copy.
If you did not receive a Form SSA-1099 by early February, contact Social Security at 1-800-772-1213 or visit your local Social Security office. You need this form to file accurately, even if you ultimately owe no tax.
State taxes on SSDI vary widely
Thirteen states do not tax SSDI at all: Alabama, Arkansas, Colorado, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Mississippi, Missouri, and Ohio. If you live in one of these states, you owe no state income tax on your benefits regardless of your income level.
Most other states follow the federal rule: you owe state tax on SSDI only if your income exceeds a threshold, and the amount taxed is similar to the federal calculation. A few states have different thresholds or tax a different percentage of benefits. Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont have their own rules that differ from federal law.
The easiest way to find your state's rule is to visit your state's department of revenue website or call their tax information line. Many state websites have a search box where you can type "Social Security" or "SSDI" and find the answer in minutes.
What to do if you think you will owe tax
If your income is close to the threshold, you have options. You can set aside money throughout the year to pay the tax when it is due. You can ask Social Security to withhold taxes from your SSDI payments — fill out Form W-4V and return it to your local Social Security office or mail it to Social Security. Withholding does not reduce the amount of tax you owe, but it spreads the payment across the year instead of requiring a lump sum in April.
You can also make estimated tax payments to the IRS if you prefer. Form 1040-ES walks you through calculating what you owe each quarter and where to send the payment.
If you are unsure whether you will owe tax, a tax preparer or the IRS Volunteer Income Tax information (VITA) program can help you estimate. VITA is free and available in most communities — search for "VITA near me" on the IRS website to find a location.
What happens if you do not pay taxes owed
If you owe tax and do not pay it, the IRS will send you a notice. You will owe the original tax plus interest and possibly penalties. The interest compounds daily. The penalty is usually 0.5 percent of the unpaid tax per month, up to 25 percent total.
If you cannot pay the full amount, you can set up a payment plan with the IRS. Call 1-800-829-1040 or visit IRS.gov to explore options. The IRS also has a hardship program if paying would create a financial emergency — explain your situation when you contact them.
The best approach is to file your return on time even if you cannot pay the full amount. Filing late carries a much steeper penalty than paying late.
Frequently Asked Questions
Can I avoid taxes on SSDI by not reporting it?
No. The Social Security Administration reports your SSDI to the IRS automatically on Form SSA-1099. The IRS knows how much you received. Not reporting it will trigger an audit and penalties. File your return and report the income.
Does working part-time while on SSDI change my tax situation?
Yes. Wages from part-time work count toward your provisional income, which can push you over the threshold and trigger tax on your SSDI. You will also owe income tax on the wages themselves. A tax preparer can show you the exact impact before you take a job.
What if I receive both SSDI and Social Security retirement benefits?
Both count toward your provisional income. Half of your combined SSDI and retirement benefits are included in the calculation. The same $25,000 or $32,000 threshold applies. You may owe tax on either benefit or both, depending on your total income.
Do I have to file a tax return if my only income is SSDI below the threshold?
Not if SSDI is your only income and it is below the filing threshold for your age and filing status. However, if you have any other income — even $1 in interest — you must file. Check the IRS website for the current filing thresholds, which change each year.
Can I claim SSDI as a dependent on someone else's return?
That depends on whether you meet the IRS definition of a dependent. SSDI itself does not disqualify you, but your total income and relationship to the person claiming you matter. A tax preparer can tell you whether this applies to your situation.
