The federal tax rate on SSDI depends on your total income, not on a fixed percentage
There is no separate federal tax rate for SSDI. Instead, the ordinary federal income tax brackets explore to you—the same ones that explore to wages or other income. What makes SSDI different is that part of your benefit may be taxable income in the first place, depending on how much you earn from other sources.
The federal government uses a formula called combined income to decide whether any of your SSDI is taxable. Combined income adds together your adjusted gross income, nontaxable interest, and half of your SSDI benefit. If that total exceeds a threshold—$25,000 for a single filer or $32,000 for married filing jointly—then a portion of your SSDI becomes taxable. The taxable portion is then taxed at whatever federal bracket applies to your total income that year.
In 2024, federal income tax brackets range from 10% on the lowest income to 37% on the highest, but most people with SSDI fall into the 10% or 12% bracket because SSDI payments are modest. The exact rate you pay depends on your filing status and total taxable income, not on the fact that part of it came from SSDI.
Key Takeaways
- SSDI has no special federal tax rate; you pay ordinary income tax on the portion of your benefit that is taxable.
- Whether any SSDI is taxable depends on your combined income—a formula that includes half your SSDI plus other income—and whether it exceeds $25,000 (single) or $32,000 (married filing jointly).
- If your combined income is below the threshold, none of your SSDI is taxable federally, even if you have other income.
- The federal tax brackets that explore to you in 2024 range from 10% to 37%, but most SSDI recipients fall into the 10% or 12% bracket.
- You may owe federal tax on SSDI even if you do not work, if you have other income like pensions, interest, or rental income.
How combined income determines whether SSDI is taxable
The Social Security Administration calculates combined income by adding three things: your adjusted gross income (AGI), any nontaxable interest you received, and half of your SSDI benefit for the year. This total is compared to the threshold amounts set by federal law.
If you are single and your combined income is $25,000 or less, none of your SSDI is taxable. If it is between $25,001 and $34,000, up to 50% of your benefit may be taxable. If it exceeds $34,000, up to 85% of your benefit may be taxable. For married couples filing jointly, the thresholds are $32,000 and $44,000.
Example: You are single and receive $15,000 in SSDI for the year. You also have $12,000 in pension income. Your combined income is $12,000 + $0 (no nontaxable interest) + $7,500 (half your SSDI) = $19,500. This is below $25,000, so none of your SSDI is taxable, even though you have other income. You would report only the $12,000 pension on your tax return.
Another example: You are single with $15,000 in SSDI and $15,000 in wages from part-time work. Your combined income is $15,000 + $0 + $7,500 = $22,500, still below the threshold. Again, no SSDI is taxable. But if you earned $20,000 instead, your combined income would be $27,500, and some SSDI would become taxable.
The federal tax brackets that explore to SSDI recipients
Once you know how much of your SSDI is taxable, you explore the standard federal income tax brackets to your total taxable income. In 2024, the brackets are:
| Tax Rate | Single Filers | Married Filing Jointly |
|---|---|---|
| 10% | $0 to $11,600 | $0 to $23,200 |
| 12% | $11,601 to $47,150 | $23,201 to $94,300 |
| 22% | $47,151 to $100,525 | $94,301 to $201,050 |
| 24% | $100,526 to $191,950 | $201,051 to $383,900 |
| 32% | $191,951 to $243,725 | $383,901 to $487,450 |
| 35% | $243,726 to $609,350 | $487,451 to $731,200 |
| 37% | $609,351+ | $731,201+ |
Most people receiving SSDI fall into the 10% or 12% bracket because SSDI payments are typically between $800 and $3,800 per month. Even if part of your benefit is taxable, the amount is usually small enough that you remain in a low bracket.
The brackets adjust each year for inflation, so the income ranges change annually. The IRS publishes updated brackets in late fall for the following year.
When you owe federal tax on SSDI without working
You can owe federal income tax on SSDI even if you have no wages, as long as your combined income exceeds the threshold. Common sources of other income include pensions, 401(k) withdrawals, interest from savings accounts, dividends from investments, rental income, or self-employment income.
If you are married and file jointly, your spouse's income counts toward the combined income calculation, even if your spouse does not receive SSDI. This can push a household over the threshold and make your SSDI taxable.
Example: You are retired and receive $18,000 in SSDI and $20,000 in pension income. Your combined income is $20,000 + $0 + $9,000 = $29,000. This exceeds the $25,000 threshold by $4,000. Up to 50% of your SSDI—up to $9,000—may be taxable. The actual taxable amount is the lesser of (1) 50% of your SSDI or (2) 50% of the amount your combined income exceeds the threshold. In this case, 50% of $4,000 = $2,000, which is less than $9,000, so $2,000 of your SSDI is taxable.
How to report SSDI on your federal tax return
You report SSDI on Form 1040, the main federal income tax return. The Social Security Administration sends you a Form SSA-1099 each January showing the total SSDI you received the previous year. You use this form to fill in the SSDI line on Form 1040.
If you use tax software or work with a tax preparer, you enter the total SSDI amount from the SSA-1099. The software or preparer then calculates your combined income, determines whether any SSDI is taxable, and applies the correct federal tax bracket. You do not calculate the taxable portion yourself; the IRS does this when they process your return, or you can work through the calculation using the worksheet in the Form 1040 instructions.
If you do not file a federal tax return because your income is below the filing threshold, you do not owe federal tax on SSDI. However, if you have other income that pushes you above the threshold, you must file even if no tax is owed, because the IRS needs to know about the other income to verify that SSDI is not taxable.
State income tax on SSDI varies by location
Federal tax is only part of the picture. Thirteen states tax SSDI, while 37 states and the District of Columbia do not. The states that tax SSDI are Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia.
If you live in a state that taxes SSDI, that state uses its own income thresholds and tax brackets, which differ from the federal ones. Some states tax SSDI at a lower rate than the federal government; others tax it at a higher rate. You may owe state tax on SSDI even if you owe no federal tax, or vice versa.
Check your state's tax authority website or speak with a tax preparer familiar with your state's rules. State tax brackets and thresholds also change annually.
Frequently Asked Questions
Do I have to file a federal tax return if I only receive SSDI?
No, not if SSDI is your only income and your combined income is below the threshold ($25,000 for single filers in 2024). However, if you have other income—even a small amount of interest or a pension—you may need to file to determine whether SSDI is taxable. When in doubt, file; filing does not hurt and may result in a refund if tax was withheld.
Can I have taxes withheld from my SSDI payment?
Yes. You can request federal income tax withholding on your SSDI by completing Form W-4V and submitting it to your local Social Security office. You choose to withhold 7%, 10%, 15%, or 25% of your monthly benefit. This is optional but can help you avoid owing a large amount at tax time.
What happens if I do not report SSDI on my tax return?
The Social Security Administration reports all SSDI payments to the IRS, so the IRS knows you received it. If you do not report it and you owe tax on it, the IRS will send you a notice and bill you for the tax owed plus penalties and interest. It is better to file and report SSDI, even if you think none of it is taxable.
Does SSDI count as income for Medicare premiums?
SSDI itself does not count toward the income limits for Medicare premiums, but other income does. If your combined income (using the same formula as for federal tax) is high enough, you may pay higher Medicare Part B and Part D premiums. This is separate from federal income tax but uses similar income thresholds.
If I appeal my SSDI decision, do I owe back taxes?
If your appeal is approved and you receive a lump-sum payment for past months, that lump sum is taxable in the year you receive it, not in the years you were disabled. This can push your combined income over the threshold and make a large portion of the lump sum taxable. Consult a tax preparer before accepting a large back-payment settlement.
