Whether You Pay Tax on Disability Depends on Your Total Income

Social Security Disability Insurance (SSDI) is taxable only if your combined income exceeds a threshold set by the IRS. Combined income means your SSDI payments plus other income sources—wages, interest, pensions, or certain other benefits. For most people receiving SSDI alone, no tax is owed. But if you work part-time, receive a pension, or have investment income, you may owe federal income tax on part of your SSDI.

The IRS uses a formula to calculate how much of your SSDI is taxable. It is not a flat percentage. The formula depends on whether you file taxes as single or married, and it produces a number between 0 and 85 percent of your benefits that could be subject to tax. The threshold amounts have not changed since 1984, which means more people cross them each year as wages and benefits rise.

State taxes are separate. Some states do not tax SSDI at all. Others tax it the same way the federal government does. A few tax it under different rules. You need to check your state's rules separately—the federal threshold does not explore to state income tax.

Key Takeaways

  • SSDI is only taxable if your combined income (SSDI plus all other income) exceeds $25,000 for single filers or $32,000 for married couples filing jointly.
  • The IRS formula taxes between 0 and 85 percent of your SSDI, depending on how much your combined income exceeds the threshold.
  • Work income, pensions, interest, and certain other benefits all count toward the combined income threshold.
  • State tax rules for SSDI vary widely; some states do not tax it at all, while others use different thresholds than the federal government.
  • You report SSDI on your tax return using the same form as other income, and the Social Security Administration sends you a statement each January showing what you received.

How the IRS Calculates Taxable SSDI

The IRS uses two tiers to determine how much of your SSDI is taxable. The first tier applies to the amount by which your combined income exceeds $25,000 (single) or $32,000 (married filing jointly). If your combined income is below these thresholds, none of your SSDI is taxable, and you owe no federal tax on it.

Once your combined income exceeds the first threshold, up to 50 percent of the excess becomes taxable. For example, if you are single and your combined income is $30,000, the excess is $5,000. Half of that—$2,500—may be taxable SSDI.

The second tier kicks in if your combined income exceeds $34,000 (single) or $44,000 (married filing jointly). At that point, an additional amount of SSDI becomes taxable, up to a maximum of 85 percent of your total SSDI for the year. This second tier is more complex because it involves calculating the excess over the second threshold and comparing it to the amount already taxed under the first tier.

The Social Security Administration sends you a Form SSA-1099 each January showing how much SSDI you received in the previous year. You use this amount to calculate your combined income and determine whether any of it is taxable. If you are unsure whether you owe tax, a tax preparer or the IRS can help you work through the calculation.

What Counts as Income for the Threshold

Combined income includes SSDI plus all other income sources. The IRS counts wages from work, self-employment income, interest, dividends, capital gains, rental income, and pensions. It also includes certain other government benefits, though the rules vary by benefit type.

Some income sources do not count toward the threshold. Supplemental Security Income (SSI) does not count. Veterans benefits do not count. Certain railroad retirement benefits do not count. Gifts and inheritances do not count. The key is whether the IRS considers it taxable income—if it is not taxable to you, it usually does not count toward the SSDI threshold either.

If you work while receiving SSDI, your wages count in full toward combined income. This is important because work income can push you over the threshold even if your SSDI alone would not be taxable. For example, if you earn $20,000 in wages and receive $10,000 in SSDI, your combined income is $30,000, which exceeds the $25,000 single threshold by $5,000.

State Income Tax Rules for SSDI

Thirteen states do not tax SSDI at all: Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Mississippi, Missouri, Oklahoma, and Pennsylvania. If you live in one of these states, you owe no state income tax on your SSDI, regardless of your combined income.

Most other states follow the federal rule: SSDI is taxable only if your combined income exceeds the federal threshold. However, some states use different threshold amounts or different calculation methods. Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont have their own rules that may result in more or less of your SSDI being taxable than under federal rules.

You must check your state's tax agency website or contact them directly to learn the rule for your state. The federal threshold does not automatically explore to state taxes, and assuming it does can lead to underpayment or overpayment of state tax.

Reporting SSDI on Your Tax Return

You report SSDI on your federal tax return using Form 1040 or Form 1040-SR (for people 65 and older). The Social Security Administration sends you Form SSA-1099 by January 31 each year, showing the total SSDI you received in the prior year. You use this amount to calculate whether any of it is taxable.

If you use tax software or a tax preparer, you enter the amount from Box 5 of your Form SSA-1099. The software or preparer then calculates your combined income and determines how much SSDI is taxable. You report the taxable amount on the appropriate line of your return.

If you file by hand, you will need to work through the IRS worksheet in the instructions to Form 1040 or consult IRS Publication 915, which explains the calculation in detail. The worksheet is lengthy, but it walks you through each step. Many people find it easier to use tax software or hire a preparer rather than calculate it by hand.

You must file a return even if you owe no tax, if your income is above the filing threshold for your age and filing status. The filing threshold is separate from the SSDI taxability threshold. For 2024, the filing threshold for a single person under 65 is $14,600 in gross income. If your combined income exceeds this amount, you must file a return.

What Happens if You Owe Tax on SSDI

If you owe federal income tax on SSDI, you pay it the same way you would pay tax on any other income. You can pay when you file your return, or you can arrange to have the Social Security Administration withhold tax from your SSDI payments throughout the year.

To request withholding, you file Form W-4V with the Social Security Administration. You can choose to have 7, 10, 12, or 22 percent of your SSDI withheld for federal income tax. Withholding reduces the amount you receive each month but prevents a large tax bill when you file your return. Many people find this easier than paying a lump sum in April.

If you do not withhold and owe tax, you can pay the full amount with your return, or you can set up a payment plan with the IRS if you cannot pay in full. The IRS charges interest and penalties on unpaid tax, so paying as soon as possible is less expensive than delaying.

If you owe state income tax on SSDI, you report it on your state return and pay it according to your state's rules. Some states allow withholding from SSDI; others do not. Check with your state tax agency to learn your options.

Frequently Asked Questions

Do I have to file a tax return if I only receive SSDI?

Only if your combined income exceeds the filing threshold for your age and filing status. For 2024, that is $14,600 for a single person under 65. If you receive only SSDI and no other income, and your SSDI is below that amount, you do not have to file. However, filing may be worth it if you are owed a refund from taxes withheld or if you may have access to for a refundable tax credit.

Can I reduce my SSDI tax by earning less money?

Yes. If your work income is pushing you over the SSDI threshold, reducing your hours or earnings will lower your combined income and may reduce or eliminate the tax on your SSDI. However, you should consider the trade-off: earning less means less total income, even if it saves you some tax. A tax preparer can help you model different income scenarios.

What if I disagree with the amount on my Form SSA-1099?

Contact the Social Security Administration when ready. You can call 1-800-772-1213 or visit your local Social Security office. Bring your records showing what you actually received. If there is an error, the Social Security Administration will issue a corrected form, and you can file an amended return if needed.

Does Medicare premium withholding count as income for the SSDI tax threshold?

No. The amount withheld from your SSDI to pay your Medicare Part B or Part D premiums does not count as income. Only the amount you actually receive counts. However, the premiums themselves do not reduce your combined income either—they are deducted after the tax calculation.

If I live in a state that does not tax SSDI, do I still owe federal tax?

Yes. State and federal tax are separate. Living in a state that does not tax SSDI saves you state tax only. You still owe federal income tax on SSDI if your combined income exceeds the federal threshold, regardless of where you live.
