Whether you pay taxes on SSDI depends on your total income, not just your disability payments
You may owe federal income tax on your Social Security Disability Insurance (SSDI) benefits if your combined income exceeds a certain threshold. Combined income means your SSDI payments plus wages, interest, dividends, and other income added together. The IRS does not tax SSDI in isolation — it taxes the total.
For most people receiving SSDI, no tax is owed because their total income stays below the threshold. But if you work part-time, have a spouse with income, or receive other benefits, you may cross that line. The calculation is specific and depends on your filing status and household situation.
Key Takeaways
- You calculate tax on SSDI using "combined income," which includes your disability payments plus all other income sources.
- Single filers owe tax on SSDI only if combined income exceeds $25,000; married filing jointly, $32,000; married filing separately, $0.
- If you owe tax, you typically pay tax on up to 85 percent of your SSDI benefits, not the full amount.
- The Social Security Administration sends Form SSA-1099 each January showing how much SSDI you received in the prior year.
- You can request that Social Security withhold federal income tax directly from your SSDI payments to avoid a tax bill at filing time.
How the IRS calculates combined income for SSDI
The IRS uses a formula called combined income to determine whether any of your SSDI is taxable. Combined income is your adjusted gross income (AGI) plus nontaxable interest plus half of your SSDI benefits. That half-benefit figure is the key: the IRS counts 50 percent of what you received in SSDI as part of the income calculation, even though it may not be taxable itself.
Once you know your combined income, you compare it to a threshold that depends on your filing status. If your combined income is below the threshold, none of your SSDI is taxable. If it exceeds the threshold, a portion of your benefits becomes taxable income.
Example: You are single and received $15,000 in SSDI during the year. You also earned $12,000 from part-time work. Your combined income is $12,000 (wages) plus $7,500 (half of SSDI) = $19,500. The threshold for single filers is $25,000, so you owe no tax on your SSDI.
Income thresholds by filing status
| Filing Status | Threshold | What it means |
|---|---|---|
| Single | $25,000 | If combined income exceeds $25,000, some SSDI is taxable. |
| Married filing jointly | $32,000 | If combined income exceeds $32,000, some SSDI is taxable. |
| Married filing separately | $0 | If you file separately and lived with your spouse at any time during the year, all SSDI is taxable. |
| Head of household | $25,000 | Same threshold as single filers. |
These thresholds have not changed since 1984 and do not adjust for inflation. That means more people cross the threshold each year as wages and other income rise.
How much of your SSDI becomes taxable
If your combined income exceeds the threshold, the IRS does not tax all of your SSDI. Instead, you pay tax on the lesser of two amounts: either 50 percent of your benefits, or 50 percent of the amount by which your combined income exceeds the threshold.
In some cases, up to 85 percent of your SSDI can become taxable. This happens when your combined income is high enough that the first calculation (50 percent of excess over threshold) reaches a second threshold. For single filers, that second threshold is $34,000; for married filing jointly, $44,000.
The math is complex, and the IRS worksheet in the tax instructions walks through it step by step. Many people use tax software or a tax preparer to handle this calculation because a mistake can lead to underpayment or overpayment of tax.
How to report SSDI on your tax return
Social Security sends you Form SSA-1099 each January for the prior year. This form shows the total SSDI you received. You enter this amount on your tax return, usually on Form 1040 or Form 1040-SR (for people 65 and older).
You do not file the SSA-1099 with your return — you keep it for your records. But you must report the income it shows. If you received SSDI from more than one source (for example, your own disability benefit and a spousal benefit), Social Security combines them on a single SSA-1099.
If you did not receive an SSA-1099 by early February, contact Social Security at 1-800-772-1213 to request a replacement. You will need it to file your return accurately.
Requesting tax withholding from your SSDI payments
You can ask Social Security to withhold federal income tax directly from your SSDI payment each month. This reduces the amount you receive but prevents a large tax bill when you file. Withholding is voluntary and you can change or stop it at any time.
To request withholding, complete Form W-4V (Voluntary Withholding Request) and mail it to your local Social Security office, or bring it in person. You can also request withholding when you explore for benefits or call 1-800-772-1213 to have a representative help you set it up.
You choose the withholding rate: 7, 10, 15, or 25 percent of your monthly benefit. Many people choose 10 percent as a middle ground. The amount withheld appears on your SSA-1099 as federal income tax withheld, which reduces the tax you owe when you file.
State income tax on SSDI
Most states do not tax SSDI benefits. However, a small number of states — including Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont — tax SSDI under certain conditions. The rules vary by state and depend on your total income and filing status.
If you live in one of these states, contact your state tax authority or a tax preparer familiar with your state's rules. Some states exempt SSDI entirely if your income is below a certain level, while others tax it the same way the IRS does. State tax forms and instructions usually explain the rule for your situation.
Frequently Asked Questions
Do I have to file a tax return if my only income is SSDI?
Not necessarily. If SSDI is your only income and it is below the filing threshold for your age and filing status, you do not have to file. However, if you had federal income tax withheld from your SSDI, you should file to get a refund of that withholding.
What if I work and receive SSDI — how does that affect my taxes?
Your work income counts toward your combined income, which may push you over the threshold and make some SSDI taxable. Additionally, if you are under full retirement age and earn above a certain amount, Social Security may reduce your benefit payment itself (separate from tax). Report all wages on your tax return.
Can I deduct medical expenses related to my disability?
Yes, if your medical expenses exceed 7.5 percent of your adjusted gross income, you can deduct the excess on Schedule A (itemized deductions). This applies to all taxpayers, not just those receiving SSDI. You must itemize rather than take the standard deduction to claim this.
What if Social Security overpaid me — do I owe tax on the overpayment?
No. If Social Security overpaid you and you repaid it, you report only the net amount you actually kept. If you repaid it in a year after you received it, you may be able to claim a deduction or credit for the repayment. Consult a tax preparer or the IRS for your specific situation.
How do I know if I need to file if my income is borderline?
Use the IRS worksheet in Publication 915 (Social Security and Equivalent Railroad Retirement Benefits) to calculate whether any SSDI is taxable. If the result is zero, you owe no tax on SSDI. If you have other income sources or are unsure, a tax preparer can review your situation quickly.
