Most SSDI recipients pay no federal income tax on their benefits

Whether you owe federal income tax on your SSDI depends on your combined income—not just your SSDI amount. For most people receiving SSDI, the answer is straightforward: you will not owe federal income tax on those benefits. The IRS uses a formula that includes your SSDI, other income, and nontaxable interest to determine if any of your benefits are taxable. If your combined income stays below a certain threshold, you pay nothing.

The thresholds are the same in 2025 as they have been for decades. For a single filer, if your combined income is $25,000 or less, none of your SSDI is taxable. For married couples filing jointly, the threshold is $32,000. These numbers do not change year to year, which means most SSDI recipients—especially those with no other income—will never cross them.

The reason most people avoid the tax is straightforward: SSDI is usually the only income they receive. If you have no wages, no self-employment income, and no investment returns, your combined income is just your SSDI amount, which almost certainly stays under the threshold.

Key Takeaways

  • If your combined income is $25,000 or less (single) or $32,000 or less (married filing jointly), you owe no federal income tax on SSDI in 2025.
  • Combined income includes SSDI, wages, self-employment income, interest, dividends, and certain other sources—not just SSDI alone.
  • Most SSDI recipients have no other income and therefore pay no tax on their benefits.
  • If you do cross the threshold, only a portion of your SSDI becomes taxable, not all of it.
  • State income tax on SSDI varies by state; some states tax it, others do not, regardless of federal rules.

When SSDI becomes taxable and how much

SSDI becomes taxable only if your combined income exceeds the threshold for your filing status. Combined income is calculated by adding your SSDI, wages, self-employment income, interest, dividends, and certain other income sources. Nontaxable interest (such as from municipal bonds) counts toward the threshold but does not count as income itself.

If you do cross the threshold, the IRS does not tax all of your SSDI. Instead, it taxes the lesser of two amounts: either 50% of the amount by which your combined income exceeds the threshold, or 50% of your total SSDI benefits. In rare cases where combined income is very high, up to 85% of your SSDI can become taxable, but this applies only to a small number of recipients with substantial other income.

Example: A single person receives $15,000 in SSDI and earns $12,000 in wages. Combined income is $27,000. This exceeds the $25,000 threshold by $2,000. The taxable portion is the lesser of 50% of $2,000 ($1,000) or 50% of $15,000 ($7,500). The taxable amount is $1,000. The remaining $14,000 in SSDI is not taxed.

Sources of income that push you over the threshold

Wages and self-employment income are the most common reasons an SSDI recipient's combined income rises above the threshold. Part-time work, gig economy earnings, or a spouse's income (if filing jointly) can all trigger the calculation. Interest and dividends from savings or investments also count, even if the amounts are small.

Certain income sources do not count toward the threshold. These include Supplemental Security Income (SSI), workers' compensation, veterans' benefits, and some other information programs. Nontaxable portions of pensions and annuities also do not count. If you receive a lump-sum settlement or back pay from a lawsuit, check with a tax professional about how it affects your combined income, because the treatment depends on what the payment is for.

If you are unsure whether a particular income source counts, the IRS Publication 915 (Social Security and Equivalent Railroad Retirement Benefits) lists all sources that factor into the combined income calculation. You can also contact the Social Security Administration or a tax professional to confirm.

How to report SSDI on your tax return

The Social Security Administration sends you a Form SSA-1099-SM each January showing the total SSDI you received in the prior year. You use this form to report your benefits on your federal tax return. If none of your SSDI is taxable, you may still need to file a return depending on your other income, but you will not report any SSDI as taxable income.

If part of your SSDI is taxable, you report the taxable portion on line 5b of Form 1040 (or the equivalent line on your return form). The IRS worksheet in Publication 915 walks you through the calculation step by step. Many tax software programs also calculate this automatically if you enter your SSDI amount and other income.

You do not have to pay estimated quarterly taxes on SSDI, even if some of it is taxable. You can instead have taxes withheld from your SSDI payment if you expect to owe. Contact Social Security to request withholding, and they will reduce your monthly payment by the amount you specify.

State income tax on SSDI varies

Federal tax rules do not explore to state income tax. Some states do not tax SSDI at all, regardless of your income level. Other states tax SSDI the same way the federal government does, using the combined income threshold. A few states have their own rules that differ from both federal law and each other.

States that do not tax SSDI include Alabama, Arizona, Arkansas, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Nevada, New Hampshire, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Virginia, Washington, West Virginia, and Wyoming. If you live in any of these states, you owe no state income tax on your SSDI, period.

If you live in a state that does tax SSDI, check your state's tax agency website or contact them directly to learn the rules. Some states use the federal threshold; others have different income limits or tax rates. Your state tax return instructions will explain how to report SSDI benefits.

What to do if you think you owe tax on SSDI

If your combined income exceeds the threshold and you believe some of your SSDI is taxable, you have two main options: file a tax return and pay the tax owed, or request withholding from your SSDI payment going forward.

To request withholding, contact Social Security by phone at 1-800-772-1213, by mail to your local Social Security office, or through your my Social Security account online. Tell them you want to have federal income tax withheld from your monthly SSDI payment. You specify the dollar amount to withhold each month, and Social Security deducts it before sending you your benefit. This does not change the amount of SSDI you have earned; it straightforward reduces the check you receive.

If you owe tax for a prior year and have not filed, you can file a back return at any time. The IRS does not have a important date for filing, though the longer you wait, the more interest and penalties may accumulate if you owe. A tax professional or the IRS Free File program can help you prepare a return for a prior year.

Frequently Asked Questions

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

No. If SSDI is your only income and none of it is taxable (which is the case for most recipients), you are not required to file a federal tax return. However, if you have other income or if part of your SSDI is taxable, you may need to file. Check the IRS filing requirements based on your total income and filing status.

What if I work part-time and receive SSDI—will I owe tax?

Possibly. Your combined income (SSDI plus wages) determines whether any SSDI is taxable. If the total exceeds $25,000 (single) or $32,000 (married filing jointly), some of your SSDI becomes taxable. The amount taxed is usually much less than your total SSDI. A tax professional can calculate the exact amount.

Can I avoid paying tax on SSDI by not reporting my other income?

No. All income must be reported on your tax return, and the IRS cross-checks your return against reports from employers, banks, and other sources. Failing to report income can result in penalties, interest, and potential criminal charges. If you owe tax, it is better to file and pay than to ignore it.

If I have taxes withheld from my SSDI, does that reduce my benefit amount permanently?

No. Withholding is temporary and applies only to the months you request it. Your SSDI benefit amount itself does not change. You can adjust or stop withholding at any time by contacting Social Security.

Does receiving SSDI affect my ability to claim dependents or other tax deductions?

SSDI does not prevent you from claiming dependents or other deductions you are may have access to to. Your tax filing status and deductions are based on your household situation and income, not on whether you receive SSDI. A tax professional can help you determine what deductions explore to your situation.
