Most SSDI recipients pay no federal income tax on their benefits

Whether you owe federal income tax on your SSDI benefits depends on your combined income—not just what Social Security sends you. Combined income includes your SSDI payments plus half of those payments plus any other income you have (wages, interest, pensions). If your combined income stays below a certain threshold, you owe nothing. If it exceeds that threshold, you may owe tax on up to 85 percent of your benefits.

The threshold is low: $25,000 for single filers and $32,000 for married couples filing jointly. These numbers have not changed since 1984. Because of this, most people receiving SSDI alone—with no other income—will never owe federal tax on their benefits. The tax applies mainly to people who have both SSDI and other substantial income, such as wages from work or a pension.

State income tax is separate. Some states tax SSDI benefits; most do not. You need to check your specific state's rules, because federal tax rules do not control state decisions.

Key Takeaways

  • You calculate combined income by adding your SSDI payment plus half your SSDI payment plus any other income you receive.
  • If your combined income is below $25,000 (single) or $32,000 (married filing jointly), you owe no federal tax on SSDI.
  • If combined income exceeds the threshold, you may owe tax on up to 85 percent of your SSDI benefits, depending on how far over you go.
  • State tax rules vary—some states do not tax SSDI at all, while others follow federal rules or have their own thresholds.
  • You report SSDI on your federal tax return using Form 1040 and Schedule 1, even if you owe no tax.

How to calculate your combined income

The IRS uses a specific formula to determine whether your SSDI is taxable. Start with your SSDI payment for the year. Then add half of that amount. Then add all your other income—wages, self-employment income, interest, dividends, pensions, rental income, anything else. That total is your combined income.

Example: You receive $15,000 in SSDI for the year and earn $12,000 from part-time work. Half your SSDI is $7,500. Combined income is $15,000 + $7,500 + $12,000 = $34,500. Since $34,500 exceeds $25,000, some of your SSDI may be taxable.

The calculation stops there for most people. You do not subtract deductions or credits when figuring combined income—you use the raw numbers. This is why someone with modest income can end up owing tax on SSDI even though they would not owe tax on that same income if it came from wages alone.

The two-tier tax system for SSDI benefits

Once you know your combined income exceeds the threshold, the IRS applies a two-tier system to determine how much of your SSDI is taxable. The first tier covers the amount between the threshold and $9,000 above it (or $12,000 for married couples). The second tier covers anything above that.

In the first tier, up to 50 percent of your SSDI can be taxable. In the second tier, up to 85 percent can be taxable. Most people fall into the first tier only. You reach the second tier only if your combined income is very high—typically $34,000 or more for single filers.

The IRS publishes a worksheet each year to calculate the exact amount. The worksheet is on Form 1040 instructions or in IRS Publication 915. Because the math is complex and depends on your specific income mix, many people use tax software or a tax preparer to get the number right.

Reporting SSDI on your federal tax return

You report SSDI on Form 1040, the main federal income tax return. The Social Security Administration sends you a Form SSA-1099 each January showing how much you received in the prior year. You use that number on your return.

If you have other income, you also report that on Form 1040 and Schedule 1. Even if you owe no tax on your SSDI, you may still need to file a return if your other income crosses the filing threshold. The filing threshold depends on your age and filing status and changes each year.

If you do owe tax on SSDI, you can pay it when you file, or you can arrange to have Social Security withhold taxes from your monthly benefit. To set up withholding, contact Social Security directly or fill out Form W-4V and send it to your local Social Security office. Withholding does not reduce your benefit amount—it just sets aside part of your payment for taxes.

State income tax on SSDI

Thirty-nine states do not tax SSDI benefits at all. Eleven states tax SSDI under their own rules, which may differ from federal rules. Some of these states follow the federal combined-income test; others use different thresholds or tax all SSDI income.

The states that tax SSDI are Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont. If you live in one of these states, contact your state tax authority or a tax preparer familiar with your state's rules. State thresholds and tax rates vary, and some states offer exemptions or deductions that the federal government does not.

If you move to a different state during the year, you may owe tax to both states for the portion of the year you lived in each. State tax returns are separate from your federal return and have their own filing important date and requirements.

What happens if you do not report SSDI on your tax return

Social Security reports all SSDI payments to the IRS. If you owe tax and do not file, the IRS will eventually contact you. Penalties and interest accrue on unpaid tax, and the debt can affect your credit. If you owe a large amount, the IRS can offset your tax refund or take other collection action.

If you are unsure whether you need to file, use the IRS filing requirement worksheet or contact the IRS directly. Filing when you do not owe tax does not hurt you, and it may help—for example, if you are due a refund from tax credits or withholding.

If you have not filed in prior years and think you may owe tax, you can still file back returns. The IRS generally does not pursue criminal charges for honest mistakes, but the sooner you file, the lower your penalties will be.

Working while receiving SSDI and managing your tax burden

If you work and receive SSDI, your wages count toward combined income, which can push you into taxable SSDI territory. However, SSDI has its own work incentive rules that allow you to earn money without losing your benefit when ready. These work incentives do not change your tax calculation—your wages still count as income for tax purposes—but they do let you test work without losing your entire benefit.

The most common work incentive is the Trial Work Period, which lets you earn any amount for nine months without losing your benefit. After the Trial Work Period ends, your benefit continues for a grace period while the Social Security Administration measures your average earnings. If your average earnings stay below the Substantial Gainful Activity level (roughly $1,550 per month in 2024, though this changes yearly), you keep your full benefit.

Even if you lose your SSDI benefit due to work, you may still owe tax on the SSDI you received during the year. Plan for this when budgeting your work income, especially if you are in a state that taxes SSDI.

Frequently Asked Questions

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

No. If SSDI is your only income and your combined income is below the threshold ($25,000 for single filers), you have no tax filing requirement. However, if you had taxes withheld from your SSDI, you may want to file to get a refund.

Can I reduce my SSDI tax by claiming deductions?

No. The combined-income test uses gross income before deductions. Standard deductions, itemized deductions, and credits do not reduce the amount of SSDI that becomes taxable. However, credits like the Earned Income Tax Credit can reduce the total tax you owe after the SSDI portion is calculated.

What if I receive both SSDI and SSI?

SSI (Supplemental Security Income) is never taxable. Only SSDI is subject to the tax rules described here. If you receive both, only your SSDI counts toward combined income, and only SSDI can be taxed.

If I have taxes withheld from my SSDI, will I get a refund?

You may. If you withhold more tax than you actually owe, filing a return will result in a refund. Withholding is an estimate, and your actual tax depends on your final combined income for the year.

Does my spouse's income affect whether my SSDI is taxable?

Only if you file a joint return. If you file jointly, you combine both spouses' incomes and use the married filing jointly threshold ($32,000). If you file separately, each spouse's SSDI is calculated using only that spouse's income and the single filer threshold.
