You may owe federal income tax on your SSDI benefits, depending on your total income and filing status
Social Security Disability Insurance (SSDI) is not automatically tax-free. The Social Security Administration taxes a portion of your benefits if your combined income exceeds a threshold set by the IRS. Combined income includes your SSDI payments, wages, interest, dividends, and certain other sources—not just earnings from work.
Whether you actually owe tax depends on two things: how much you received in SSDI that year, and what other income you had. If your combined income stays below the IRS threshold for your filing status, you owe nothing. If it exceeds the threshold, you may owe tax on up to 85 percent of your benefits.
The IRS does not automatically withhold tax from SSDI payments the way it does from paychecks. You are responsible for reporting the income yourself when you file your annual return, or for requesting that Social Security withhold tax from your payments in advance.
Key Takeaways
- You owe federal income tax on SSDI only if your combined income (SSDI plus other income) exceeds the IRS threshold for your filing status.
- The IRS thresholds are $25,000 for single filers and $32,000 for married filing jointly; these amounts have not changed since 1984.
- Social Security sends you a Form SSA-1099 each January showing how much you received in benefits the prior year, which you use to calculate taxable income.
- You can request that Social Security withhold federal income tax from your monthly SSDI payment to avoid owing a large amount at tax time.
- State income tax rules vary; some states do not tax SSDI at all, while others follow the federal formula.
How the IRS calculates whether you owe tax on SSDI
The IRS uses a formula called combined income to determine how much of your SSDI is taxable. Combined income is the sum of your adjusted gross income (AGI) plus nontaxable interest plus half of your Social Security benefits.
For example: if you earned $15,000 in wages, received $12,000 in SSDI, and had $500 in nontaxable interest, your combined income would be $15,000 + $500 + ($12,000 ÷ 2) = $21,500. If you file as single, your threshold is $25,000, so you would owe no tax. If you earned $20,000 instead, your combined income would be $26,500, which exceeds the $25,000 threshold by $1,500, and you would owe tax on a portion of your benefits.
The actual amount of SSDI that becomes taxable depends on how far you exceed the threshold and your filing status. The IRS worksheet on Form 1040 instructions walks through the calculation, but the basic rule is: you may owe tax on up to 50 percent of your benefits if you are only slightly over the threshold, or up to 85 percent if you are significantly over it.
IRS income thresholds for SSDI taxation
The IRS sets different thresholds based on your filing status. These thresholds have remained unchanged since 1984:
| Filing Status | IRS Threshold |
|---|---|
| Single | $25,000 |
| Married filing jointly | $32,000 |
| Married filing separately | $0 |
If you are married and file separately, the IRS treats almost all of your SSDI as taxable income, which is why tax professionals usually advise against this filing status if one spouse receives SSDI.
Combined income includes wages, self-employment income, interest, dividends, capital gains, rental income, and distributions from retirement accounts. It also includes income from a spouse if you file jointly. The threshold does not adjust for inflation, so more people reach it each year as wages and other income sources grow.
How to report SSDI on your federal tax return
Social Security sends you a Form SSA-1099 each January for the prior calendar year. This form shows the total amount of SSDI benefits you received. You use this amount to calculate your combined income and determine whether any of your benefits are taxable.
If you owe tax on your SSDI, you report it on your Form 1040 (the main federal income tax form) along with any other income. The IRS worksheet in the Form 1040 instructions guides you through calculating the taxable portion. You can also use tax software or work with a tax preparer who will perform the calculation for you.
You must file a return even if you owe no tax on your SSDI, if your total income exceeds the filing threshold for your age and status. The IRS filing thresholds are separate from the SSDI taxation thresholds and are higher. For 2024, a single person under 65 must file if their gross income is $14,600 or more; the threshold is higher if you are 65 or older.
Requesting tax withholding from your SSDI payment
If you know you will owe tax on your SSDI, you can ask Social Security to withhold federal income tax from your monthly payment. This reduces the amount you receive each month but prevents you from owing a large bill at tax time.
To request withholding, complete Form W-4V (Voluntary Withholding Request) and submit it to your local Social Security office, by mail, or online through your my Social Security account. On the form, you choose a withholding rate: 7 percent, 10 percent, 15 percent, or 25 percent of your monthly benefit.
You can change your withholding rate at any time, or stop withholding altogether, by submitting a new Form W-4V. Social Security will begin withholding the month after they receive your request. Keep a copy of the form for your records.
State income tax on SSDI
State tax treatment of SSDI varies widely. Some states do not tax SSDI at all. Others follow the federal formula and tax the same portion you owe to the IRS. A few states have their own thresholds or rules.
If you live in a state with income tax, check your state's tax agency website or contact them directly to learn whether SSDI is taxable in your state. Your state tax return instructions usually address this question. If your state taxes SSDI, you report it the same way you do on your federal return, using the Form SSA-1099 Social Security sends you.
Some states that do not tax SSDI still require you to file a state return if you have other income. Filing does not create a tax bill, but it may be necessary to claim a state tax credit or refund.
What to do if you cannot pay the tax you owe
If you file your return and owe tax on your SSDI but cannot pay the full amount, you have options. You can request a payment plan from the IRS, which allows you to pay in installments over time. You can also request an offer in compromise if you believe you cannot ever pay the full amount, though the IRS rarely accepts these.
Contact the IRS at 1-800-829-1040 to discuss your situation. Explain your income and expenses, and ask what payment arrangements are available. The IRS may allow you to pay monthly, and they can set up automatic payments from your bank account.
Do not ignore a tax bill. If you owe and do not pay or make a payment plan, the IRS can place a levy on your bank account or garnish other income. SSDI itself cannot be garnished for federal tax debt, but other income sources can be.
Frequently Asked Questions
Does my SSDI count toward the income limit for Medicaid or other benefits?
Yes. Most means-tested programs count your SSDI as income when determining whether you remain may be able to access. Medicaid, Supplemental Security Income (SSI), housing information, and food information all count SSDI toward their income limits. Check with each program you receive to understand how your SSDI affects your benefits.
If I work part-time and earn wages, do I still owe tax on my SSDI?
Possibly. Your combined income includes both your wages and your SSDI. If the total exceeds your IRS threshold, a portion of your SSDI becomes taxable. You may also owe tax on the wages themselves. Use the combined income formula to calculate whether you cross the threshold.
Can I deduct medical expenses or disability-related costs from my SSDI income?
No. SSDI is not treated as earned income, so you cannot claim the earned income tax credit or deduct work-related expenses. You can deduct medical expenses only if you itemize deductions on Schedule A and your total medical expenses exceed 7.5 percent of your adjusted gross income—a high bar for most people.
What if I disagree with the amount shown on my Form SSA-1099?
Contact Social Security when ready. Call 1-800-772-1213 or visit your local office with your Form SSA-1099 and your payment records. Social Security will investigate and issue a corrected form if an error occurred. You can then file an amended tax return with the correct amount.
Do I need to report my SSDI to the IRS if I do not file a tax return?
If your total income is below the filing threshold for your age and status, you are not required to file. However, if you had tax withheld from your SSDI or other sources, filing a return may result in a refund. Even if you do not owe tax, filing can be worthwhile.
