Most SSDI recipients pay no federal income tax on their benefits

Whether you owe federal income tax on SSDI depends on your total income from all sources, not on SSDI alone. The Social Security Administration does not withhold taxes from SSDI payments automatically. You only owe tax if your combined income — SSDI plus wages, pensions, interest, and other earnings — crosses a threshold set by the IRS. For most people receiving SSDI, that threshold is high enough that they never reach it.

The calculation is specific and has nothing to do with how much SSDI you receive. It is based on what the IRS calls combined income: half your SSDI benefits plus all your other income. If that number stays below the IRS threshold for your filing status, you owe no federal tax on any of it. If it goes above the threshold, you may owe tax on up to 85 percent of your SSDI benefits.

State income tax is separate. Some states do not tax SSDI at all. Others tax it the same way the federal government does. A few states have their own rules. You need to check your state's tax authority website or ask a tax preparer about your state specifically.

Key Takeaways

  • You owe federal income tax on SSDI only if your combined income (half your SSDI plus all other income) exceeds the IRS threshold for your filing status.
  • For 2024, the threshold is $25,000 for single filers and $32,000 for married couples filing jointly; these amounts change yearly.
  • If you do owe tax, you pay it on up to 85 percent of your SSDI benefits, not on the full amount.
  • State income tax rules for SSDI vary widely — some states do not tax it, others do, and you must check your own state's rules.
  • You can ask Social Security to withhold taxes from your SSDI payment each month so you do not owe a large amount at tax time.

How the IRS calculates whether you owe tax on SSDI

The IRS uses a two-step process. First, it adds up your combined income: take half of your SSDI benefits for the year, then add all your other income (wages, self-employment income, pensions, interest, dividends, rental income, and any other sources). That total is your combined income.

Second, the IRS compares your combined income to a threshold. If your combined income is below the threshold for your filing status, you owe no federal tax on your SSDI. If it is above the threshold, you may owe tax on up to 85 percent of your benefits. The exact amount depends on how far above the threshold you are.

The thresholds are set by law and change each year. For 2024, the threshold is $25,000 for single filers, $32,000 for married couples filing jointly, and $0 for married couples filing separately. These numbers are adjusted annually for inflation, so they will be different in 2025 and beyond. You can find the current year's thresholds on the IRS website or ask a tax preparer.

When you might owe tax on SSDI

You are most likely to owe tax on SSDI if you have other income. Common situations include working part-time while receiving SSDI, receiving a pension or retirement income, or having investment income. Even small amounts add up: if you are single and receive $20,000 in SSDI and earn $10,000 in wages, your combined income is $20,000 (half of $20,000 plus $10,000), which is below the $25,000 threshold, so you owe no tax. But if you earn $15,000 in wages instead, your combined income is $25,000, which meets the threshold exactly, and you may owe tax.

You can also owe tax if you have interest or dividend income, even if you do not work. If you have savings or investments that generate $5,000 or more per year in interest or dividends, that counts toward your combined income.

If you are married and file jointly, both spouses' income counts. If your spouse works and you receive SSDI, the household's combined income includes both your SSDI (half of it) and your spouse's full income. This can push you over the threshold even if neither of you has a large income individually.

What happens if your combined income exceeds the threshold

If your combined income is above the threshold, you do not automatically owe tax on all your SSDI. The IRS taxes you on the lesser of two amounts: either 50 percent of the excess over the threshold, or 85 percent of your total SSDI benefits. In most cases, the first number is smaller, so you end up owing tax on a smaller portion of your benefits.

Here is a concrete example: suppose you are single, receive $20,000 in SSDI, and earn $15,000 in wages. Your combined income is $25,000 (half of $20,000 plus $15,000). The threshold for single filers is $25,000, so you are $0 over the threshold. You owe no tax. But if you earn $20,000 in wages instead, your combined income is $30,000, which is $5,000 over the threshold. The IRS would tax you on 50 percent of that $5,000 excess, which is $2,500 of your SSDI benefits.

The calculation becomes more complex if your combined income is very high, but most SSDI recipients do not reach that point. If you think you might owe tax, a tax preparer or the IRS can walk you through the exact calculation for your situation.

Requesting tax withholding from your SSDI payment

If you know you will owe federal income tax, you can ask Social Security to withhold money from your SSDI payment each month. This way, you will not owe a large amount when you file your tax return. You request withholding by filling out Form W-4V (Voluntary Withholding Request) and sending it to your local Social Security office or mailing it to Social Security.

You can choose to have 10 percent, 15 percent, 25 percent, or 50 percent of your benefit withheld each month. Social Security will then send that amount to the IRS on your behalf. When you file your tax return, that withheld amount counts as a payment toward your tax bill, just like withholding from a paycheck would.

Requesting withholding is optional. You can also pay your taxes in full when you file your return, or you can make quarterly estimated tax payments to the IRS. But withholding is often the simplest approach because the money comes out automatically and you do not have to remember to send a payment.

State income tax on SSDI

Thirty-seven states do not tax SSDI benefits at all, regardless of your income. If you live in one of those states, you owe no state income tax on your SSDI, period. The remaining states have different rules. Some states use the same federal threshold and calculation as the IRS. Others have their own thresholds or tax SSDI differently.

A few states tax SSDI only if your total income (not combined income) exceeds a certain amount, or only if you are above a certain age. Colorado, for example, does not tax SSDI for people over 55. You need to check your state's tax authority website or contact them directly to learn your state's specific rules. A tax preparer in your state can also tell you whether you owe state tax on SSDI.

Reporting SSDI on your tax return

When you file your federal income tax return, Social Security sends you a Form SSA-1099 by January 31 each year. This form shows how much SSDI you received in the previous year. You use this form to report your SSDI income on your tax return. If you use tax software or a tax preparer, you will enter the amount from the SSA-1099 into the appropriate box on your return.

You must report SSDI even if you do not owe tax on it. The IRS uses the SSA-1099 to verify your income, so leaving it off your return can trigger an audit or a notice. If you do not receive an SSA-1099 by early February, contact Social Security to request a replacement.

Frequently Asked Questions

Does Social Security automatically withhold taxes from my SSDI payment?

No. Social Security does not withhold federal income tax automatically. You must request withholding by submitting Form W-4V to your local Social Security office. If you do not request withholding and you owe tax, you will owe it when you file your return.

What if I earn money while receiving SSDI — do I have to pay tax on both?

Your wages are always taxable. Whether your SSDI is taxable depends on your combined income (half your SSDI plus all your other income). If that total exceeds the IRS threshold, part of your SSDI becomes taxable. You may owe tax on both your wages and part of your SSDI.

Can I reduce my SSDI tax by not reporting other income?

No. All income must be reported to the IRS. Failing to report income is tax fraud and can result in penalties, interest, and criminal charges. If you have questions about what counts as income, ask a tax preparer or the IRS.

What if my state does not tax SSDI but the federal government does?

You would owe federal income tax but not state income tax. You would file your federal return and report the tax you owe to the IRS, but you would not owe anything to your state. Your state tax return (if you file one) would not include SSDI as taxable income.

Do I have to file a tax return if I only receive SSDI and no other income?

If SSDI is your only income and your combined income is below the IRS threshold, you do not owe federal income tax and generally do not have to file a federal return. However, you may want to file anyway if you are due a refund from taxes withheld or if you may have access to for the Earned Income Tax Credit or other refundable credits.
