Social Security Disability benefits are taxable income in some situations, but most people who receive SSDI pay no federal tax on their benefits

Whether you owe federal income tax on your SSDI depends on your combined income — not just what you receive from Social Security. Combined income is the sum of your adjusted gross income, nontaxable interest, and half of your Social Security benefits. If that total falls below a certain threshold, you owe no tax. If it exceeds the threshold, you may owe tax on a portion of your benefits.

The thresholds are set by the IRS and do not change with inflation. For 2024, if you file as single and your combined income is $25,000 or less, you owe no federal tax on your SSDI. If you file as married filing jointly, the threshold is $32,000. Above those amounts, you may owe tax on up to 85 percent of your benefits, depending on how far over the threshold you go.

State taxes are separate. Some states tax SSDI; most do not. Your state's tax agency, not the IRS, sets that rule. You can find your state's policy by searching "[your state] Social Security disability tax" or by calling your state revenue office.

Key Takeaways

  • Combined income — not SSDI alone — determines whether you owe federal tax on your benefits.
  • For 2024, single filers with combined income of $25,000 or less and married filers with $32,000 or less owe no federal tax on SSDI.
  • If your combined income exceeds the threshold, you may owe tax on up to 85 percent of your benefits.
  • Most states do not tax SSDI, but a few do; check your state revenue office to know for certain.
  • The Social Security Administration sends Form SSA-1099 each January showing your annual benefit amount, which you use to calculate combined income.

How combined income is calculated

Combined income is not the same as your total income. The IRS defines it as your adjusted gross income (AGI) plus any nontaxable interest you earned plus half of your Social Security benefits. If you have no other income besides SSDI, your combined income is half your SSDI amount, which means you will almost certainly be below the threshold.

Other income that counts toward combined income includes wages from work, self-employment income, pensions, interest, dividends, rental income, and income from a spouse if you file jointly. Income that does not count includes Supplemental Security Income (SSI), workers' compensation, and veterans' benefits.

Example: You receive $1,500 per month in SSDI ($18,000 per year). You also work part-time and earn $10,000 in wages. Your combined income is $10,000 (wages) plus $9,000 (half your SSDI) = $19,000. Since you file as single and $19,000 is below $25,000, you owe no federal tax on your SSDI that year.

When you owe tax on a portion of your benefits

If your combined income exceeds the first threshold, the IRS uses a two-tier system to calculate how much of your SSDI is taxable. The first tier applies to combined income between the first threshold and a second threshold. The second tier applies to combined income above the second threshold.

For 2024, the second threshold is $34,000 for single filers and $44,000 for married filers filing jointly. Between the first and second threshold, up to 50 percent of your benefits may be taxable. Above the second threshold, up to 85 percent of your benefits may be taxable. The actual amount depends on how much you exceed each threshold.

The calculation is complex, and the IRS provides a worksheet in Publication 915 to work through it. Many people use tax software or a tax preparer to determine the taxable amount. You can also call the IRS at 1-800-829-1040 and ask them to calculate it for you.

Reporting SSDI on your tax return

Each January, the Social Security Administration mails you Form SSA-1099, which shows the total amount of SSDI you received in the previous year. You use this form to report your benefits on your federal tax return. If you file Form 1040 or 1040-SR, you report your SSDI on line 5b.

You must report all of your SSDI, even if none of it is taxable. The IRS uses the SSA-1099 to cross-check your return, so reporting the full amount prevents delays or notices. If you do not receive an SSA-1099 by early February, contact Social Security at 1-800-772-1213 to request one.

If you owe tax on a portion of your benefits, you report the taxable amount on your return. Tax software and tax preparers can calculate this for you based on your other income and filing status. You do not pay tax directly to Social Security; you include it on your regular federal income tax return.

Estimated tax payments and withholding

If you know you will owe tax on your SSDI, you have two options: pay estimated quarterly taxes or request that Social Security withhold taxes from your monthly benefit.

To request withholding, you fill out Form W-4V and submit it to Social Security. You can choose to have 7, 10, 12, or 22 percent of your monthly benefit withheld for federal taxes. This is simpler than calculating and paying estimated taxes yourself, and it spreads the tax payment across the year rather than requiring a lump sum at tax time.

You can request withholding online through your my Social Security account, by mail, or by phone at 1-800-772-1213. You can change or stop withholding at any time. If you choose not to withhold and do not pay estimated taxes, you may owe a penalty when you file your return.

State and local taxes on SSDI

Thirteen states tax Social Security benefits in some form: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The rules vary by state. Some tax SSDI the same way the federal government does; others have different thresholds or tax a different percentage.

If you live in one of these states, contact your state revenue office or visit its website to find the specific rules for SSDI. You may owe state tax even if you owe no federal tax, or vice versa. Some states allow you to request withholding from your SSDI the same way you do for federal taxes.

If you live in a state that does not tax Social Security, you owe no state tax on your SSDI regardless of your income level. Most states fall into this category.

What happens if you do not report SSDI income

The Social Security Administration reports all SSDI payments to the IRS. If you receive an SSA-1099 and do not report the income on your tax return, the IRS will notice the discrepancy when it matches your return to the SSA-1099. This can trigger an audit, a notice of underreported income, or a penalty.

Even if you believe none of your SSDI is taxable, you must still report the full amount on your return. The IRS will calculate whether any is taxable based on your other income. Failing to report it creates a paper trail problem that is harder to fix later than simply reporting it correctly from the start.

Frequently Asked Questions

Do I have to file a tax return if my only income is SSDI?

Not necessarily. If SSDI is your only income and your combined income is below the threshold for your filing status, you have no federal tax filing requirement. However, you may want to file anyway if you are due a refund from taxes withheld or if you may have access to for a refundable tax credit like the Earned Income Tax Credit.

Can I reduce my taxable SSDI by earning less money?

Yes. Since combined income determines whether you owe tax, earning less from work or other sources lowers your combined income and may bring you below the threshold. This is a personal financial decision that depends on your situation, and a tax preparer or financial advisor can help you think through the trade-offs.

What if I worked and paid into Social Security before I became disabled?

The tax rules are the same regardless of whether you worked before. Your SSDI is treated the same way for tax purposes as anyone else's Social Security benefits. Your work history affects how much SSDI you receive, but not whether it is taxable.

If I am married and file jointly, does my spouse's income count toward the threshold?

Yes. If you file as married filing jointly, your combined income includes both your income and your spouse's income, even if your spouse does not receive SSDI. This can push you over the threshold even if your SSDI alone would not.

Do I owe tax on back pay from SSDI?

Yes. If Social Security approves your claim and pays you a lump sum for months you were waiting for approval, that back pay counts as income in the year you receive it. This can push your combined income over the threshold in that year. You report the entire back pay amount on your Form SSA-1099.
