Whether You Owe Taxes on SSDI Depends on Your Total Income

You may owe federal income tax on part of your SSDI benefits, but only if your combined income exceeds a threshold set by the IRS. Combined income is not just your SSDI payment—it includes wages, interest, dividends, and other income sources added together in a specific way. Most people receiving SSDI alone do not owe tax, but if you work part-time, have a spouse with income, or receive other benefits, you could cross the threshold.

The IRS uses a formula called provisional income to determine whether your benefits are taxable. This formula adds half your SSDI to all your other income sources. If that total exceeds $25,000 (single filer) or $32,000 (married filing jointly), some of your SSDI becomes taxable income. The thresholds have not changed since 1984, so they affect more people now than they did decades ago.

Whether you actually owe tax also depends on your filing status, age, and whether you have other income that already requires you to file a return. A person living on SSDI alone almost never owes tax. A person with SSDI plus part-time work, a pension, or investment income may.

Key Takeaways

  • You owe tax on SSDI only if your combined income (half your SSDI plus all other income) exceeds $25,000 single or $32,000 married filing jointly.
  • Most people receiving SSDI alone do not owe federal income tax, even if they receive the full monthly benefit.
  • If you work, receive a pension, or have investment income alongside SSDI, you may cross the tax threshold and owe tax on part of your benefits.
  • You can request that the Social Security Administration withhold taxes from your SSDI payment each month to avoid a large bill at tax time.
  • State income tax on SSDI varies by state—some states do not tax SSDI at all, while others tax it under the same rules as the federal government.

How the IRS Calculates Taxable SSDI

The IRS does not tax your entire SSDI benefit. Instead, it taxes only the portion that exceeds the threshold, and only up to 85 percent of your total benefit. This means even high-income earners do not pay tax on more than 85 percent of what they receive from Social Security.

To find out whether you owe tax, calculate your provisional income: take half your SSDI for the year, add all wages, self-employment income, interest, dividends, and other income sources (but not certain items like municipal bond interest). If that total is under the threshold for your filing status, you owe no tax on your SSDI. If it exceeds the threshold, the IRS taxes the lesser of two amounts: either 50 percent of the excess over the threshold, or 85 percent of your total SSDI, whichever is smaller.

Example: A single person receives $18,000 in SSDI and earns $12,000 in part-time wages. Provisional income is ($18,000 ÷ 2) + $12,000 = $21,000. This is under $25,000, so no SSDI is taxable. If instead they earned $20,000 in wages, provisional income would be $29,000. The excess over $25,000 is $4,000. Fifty percent of that is $2,000. This person would owe tax on $2,000 of their SSDI (not the full $18,000).

When You Must File a Tax Return

You must file a federal tax return if your gross income exceeds the standard deduction for your age and filing status. For 2024, the standard deduction is $14,600 for a single person under 65, and $18,150 for a single person 65 or older. If you are married filing jointly, the threshold is higher.

SSDI counts as gross income for this purpose, but only the taxable portion—the amount calculated using the formula above. If you receive $18,000 in SSDI and have no other income, your gross income is $0 (since none of the SSDI is taxable), and you do not have to file. If you receive $18,000 in SSDI and $10,000 in wages, your gross income is at least $10,000 plus any taxable SSDI, which likely means you must file.

Even if you are not required to file, you may want to file anyway if you paid taxes through withholding or have a refundable tax credit like the Earned Income Tax Credit. Filing allows you to recover money the IRS withheld.

Requesting Tax Withholding From Your SSDI Payment

If you expect to owe tax on your SSDI, you can ask the Social Security Administration to withhold a percentage of your monthly payment. This spreads the tax bill across the year instead of requiring a lump sum at tax time. Withholding is voluntary and does not change the amount of tax you owe—it just changes when you pay it.

To request withholding, complete Form W-4V (Voluntary Withholding Request) and submit it to your local Social Security office in person, by mail, or through your online my Social Security account. You can choose to withhold 7, 10, 15, or 25 percent of your monthly benefit. The withholding begins the month after Social Security receives your form.

If you change your mind or your income changes, you can submit a new Form W-4V at any time to adjust the withholding rate or stop withholding altogether. Keep a copy of the form for your records.

State Income Tax on SSDI

Thirteen states tax SSDI benefits under their own income tax systems: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The other states and the District of Columbia do not tax SSDI at all.

States that tax SSDI generally follow the federal formula—they tax only the portion that is taxable under federal law. A few states have their own thresholds or rules. For example, some states exempt SSDI for people below a certain age or income level. Check your state's tax authority website or contact them directly to learn the specific rules where you live.

If you live in a state that taxes SSDI and you expect to owe state tax, you can request withholding for state taxes separately from federal withholding. The process varies by state, so contact your state tax authority for instructions.

Reporting SSDI on Your Tax Return

The Social Security Administration sends you a Form SSA-1099 each January showing the total SSDI you received in the previous year. Use this form to report your benefits on your federal tax return. The amount on the SSA-1099 is your total SSDI, not the taxable portion—you calculate the taxable amount yourself using the IRS formula or with tax software.

Report your SSDI on line 5b of Form 1040 (the main federal income tax form). If you use tax software, it will walk you through the calculation. If you file by hand, use the IRS worksheet in the instructions to Form 1040 to determine how much of your SSDI is taxable.

Keep your SSA-1099 with your tax records. If you received SSDI in multiple states during the year (for example, if you moved), you may receive more than one SSA-1099. Report the total from all forms.

What Happens If You Do Not Pay Taxes You Owe

If you owe tax on SSDI and do not pay it, the IRS can assess penalties and interest on the unpaid amount. The penalty for not filing a return is usually 5 percent of the unpaid tax per month (up to 25 percent total). The penalty for not paying is 0.5 percent per month. Interest accrues daily at a rate set quarterly by the IRS (currently around 8 percent annually, but this changes).

If you cannot pay the full amount, you can request a payment plan from the IRS. Short-term plans (120 days or less) are free. Long-term installment agreements have a setup fee and monthly interest, but they stop the IRS from taking collection action while you pay. Contact the IRS at 1-800-829-1040 or visit irs.gov to set up a plan.

If you believe you made an error on a past return or did not file when you should have, you can file an amended return using Form 1040-X. The IRS generally allows you to amend returns going back three years.

Frequently Asked Questions

Do I have to pay taxes if I only receive SSDI and no other income?

No. If SSDI is your only income, none of it is taxable, and you do not owe federal income tax. You also do not have to file a federal return unless your state requires it or you want to claim a refundable tax credit.

If I work part-time, how much of my SSDI becomes taxable?

It depends on how much you earn. Add half your annual SSDI to your wages and other income. If that total exceeds $25,000 (single) or $32,000 (married filing jointly), some SSDI becomes taxable. Use the IRS worksheet in Form 1040 instructions to calculate the exact amount—it is not a straightforward percentage.

Can I reduce my SSDI tax by lowering my income?

Yes, but only if you control your income. If you work, earning less would lower your provisional income and potentially move you below the tax threshold. If you have investment income, you could time when you sell investments. However, reducing income solely to avoid taxes may not be worth the trade-off in actual money received.

What if I disagree with the amount of tax the IRS says I owe on SSDI?

You can file Form 1040-X (Amended U.S. Individual Income Tax Return) if you believe the IRS made an error in calculating your taxable SSDI. Include a detailed explanation of why you disagree. If the IRS denies your claim, you can appeal or file a claim in Tax Court, though you may want to consult a tax professional first.

Does receiving SSDI affect my may be able to access for other tax credits?

SSDI itself does not reduce your may be able to access for credits like the Earned Income Tax Credit or the Child Tax Credit. However, your total income (including taxable SSDI) counts toward the income limits for these credits. If your income is high enough that some SSDI is taxable, you may also be above the limit for certain credits.
