Most people on SSDI do not pay federal income tax on their benefits, but some do — it depends on your total income from all sources.

The Social Security Administration uses a formula called "combined income" to decide whether your SSDI is taxable. Combined income includes your SSDI payment plus half of your SSDI plus any other income you have (wages, interest, pensions, rental income). If that total exceeds a threshold — $25,000 for a single filer, $32,000 for married filing jointly — then part of your SSDI becomes subject to federal income tax.

In practice, most SSDI recipients fall below these thresholds and owe no federal tax on their benefits. But if you have other income — from part-time work, a pension, investment returns, or a spouse's income — you may cross the line. State income tax is separate: thirteen states tax SSDI benefits under their own rules, regardless of the federal threshold.

Key Takeaways

  • You pay federal income tax on SSDI only if your combined income (SSDI plus half your SSDI plus other income) exceeds $25,000 single or $32,000 married filing jointly.
  • Most SSDI recipients have no federal tax liability on their benefits because their total income stays below the threshold.
  • Thirteen states — Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia — tax SSDI benefits under state law regardless of federal rules.
  • If you owe tax on SSDI, you can pay it when you file your return or request that Social Security withhold taxes from your monthly payment.
  • You must file a federal return if your gross income meets the filing threshold, even if none of it is taxable.

How the Combined Income Formula Works

The combined income threshold is the key number. To calculate yours, add: (1) your SSDI benefit amount, (2) half of your SSDI benefit amount, and (3) all other income you received that year. Other income includes W-2 wages, self-employment income, interest, dividends, rental income, pensions, distributions from retirement accounts, and income from a spouse if you file jointly.

If that sum is $25,000 or less (single) or $32,000 or less (married filing jointly), your SSDI is not taxable at the federal level. If it exceeds the threshold, up to 85 percent of your SSDI may become taxable — but the actual percentage depends on how far above the threshold you are. The IRS publishes a worksheet each year to calculate the exact amount.

Example: You receive $1,200 per month in SSDI ($14,400 per year) and earn $15,000 from part-time work. Your combined income is $14,400 + $7,200 + $15,000 = $36,600. You are $11,600 over the $25,000 threshold, so part of your SSDI becomes taxable. You would use the IRS worksheet to find the exact taxable amount, which would be less than the full $11,600 overage.

State Taxes on SSDI Benefits

Thirteen states have their own rules and tax SSDI benefits regardless of whether you owe federal tax. These states are: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. If you live in one of these states and receive SSDI, you may owe state income tax on your benefits even if your combined income is below the federal threshold.

Each state sets its own threshold and tax rate. Some states exempt SSDI entirely for certain age groups or income levels. You should check your state's tax authority website or contact them directly to learn the exact rules for your situation. Your state tax return instructions usually include a worksheet for SSDI taxation.

When You Must File a Tax Return

You must file a federal income tax return if your gross income meets the IRS filing threshold for your age and filing status, even if none of your income is taxable. For 2024, the threshold is $14,600 for a single person under 65, $18,150 for a single person 65 or older, and higher amounts for married filers.

Gross income for this purpose includes wages, self-employment income, interest, dividends, and other sources — but not SSDI itself. However, if you have any earned income (wages or self-employment), you almost certainly must file. Filing is also required if you owe self-employment tax or if you want to claim the Earned Income Tax Credit or other refundable credits.

Even if you do not owe tax, filing may be worth doing: you might be owed a refund from taxes withheld on wages, or you might may have access to for credits that result in a payment to you.

Requesting Tax Withholding From Your SSDI Payment

If you know you will owe federal income tax on your SSDI, you can ask Social Security to withhold a percentage from your monthly payment instead of paying a lump sum when you file. This works like tax withholding from a paycheck and can help you avoid a large bill in April.

To request withholding, fill out Form W-4V (Voluntary Withholding Request) and send it to your local Social Security office or mail it to the address on the form. You can choose to have 7, 10, 15, or 25 percent of your benefit withheld. You can change or stop withholding at any time by submitting a new form.

Withholding does not change how much tax you owe — it just spreads the payment across the year. If you withhold too much, you will get a refund when you file. If you withhold too little, you will owe the difference.

How to Report SSDI on Your Tax Return

SSDI benefits are reported on your federal tax return using Form 1040 and the Social Security Benefits Worksheet. The Social Security Administration sends you a Form SSA-1099 each January showing the total SSDI you received the previous year. Use this form to complete the worksheet.

The worksheet calculates how much of your SSDI is taxable based on your combined income. You then enter the taxable amount on Form 1040 as "Social Security benefits." If you use tax software, it usually walks you through this calculation automatically once you enter your SSA-1099 information.

If you live in a state that taxes SSDI, you will also report the taxable amount on your state return using your state's worksheet or instructions. State rules vary, so follow your state's specific guidance.

What Happens if You Do Not File When You Owe Tax

If you owe federal income tax and do not file, the IRS can assess penalties and interest on the unpaid amount. However, if your only income is SSDI and you are below the filing threshold, you have no filing requirement and no penalty applies.

If you have other income and owe tax but do not file, the IRS will eventually contact you. It is better to file even if you cannot pay the full amount owed — you can set up a payment plan with the IRS, and filing stops penalties from growing. If you need help, the IRS offers free tax preparation through VITA (Volunteer Income Tax information) sites, and many nonprofits offer free tax help for low-income filers.

Frequently Asked Questions

Do I have to pay taxes on SSDI if I live on very little money?

No. If your combined income (SSDI plus half your SSDI plus other income) is below $25,000 single or $32,000 married, you owe no federal tax on your SSDI. Most SSDI recipients fall below this threshold. However, if you live in one of the thirteen states that tax SSDI, you may owe state tax regardless of the federal threshold.

If I earn money from work, does that count toward the combined income threshold?

Yes. Wages from part-time or full-time work count as "other income" in the combined income formula. This can push you over the threshold and make part of your SSDI taxable. However, earning money does not reduce your SSDI payment itself — that is a separate rule called the earnings test.

What if I am married and my spouse has income?

If you file jointly, your spouse's income counts toward your combined income threshold. The threshold for married filing jointly is $32,000. If you file separately, your spouse's income may still count depending on whether they received SSDI. Check the IRS worksheet for your specific situation.

Can I avoid paying taxes on SSDI by not filing a return?

No. If you owe tax, not filing does not erase the debt — it adds penalties and interest. If your income is below the filing threshold, you have no requirement to file. But if you are above the threshold and owe tax, filing is required and is the only way to resolve your tax liability.

Do I need to file taxes if SSDI is my only income?

Only if your combined income exceeds $25,000 single or $32,000 married. If SSDI is your only income and you are below that threshold, you have no federal filing requirement. However, check your state's rules — some states require filing even when federal filing is not required.
