You may owe federal income tax on your SSDI benefits, but most people who receive only SSDI do not

Whether you file taxes on SSDI depends on your total income for the year. If SSDI is your only income, you almost certainly will not owe tax. But if you have other income—wages, self-employment earnings, interest, dividends, or distributions from retirement accounts—you may have to count part of your SSDI as taxable income.

The IRS uses a formula to determine how much of your benefit is taxable. You start by adding half of your SSDI benefit to your other income. If that sum exceeds a threshold amount (called your "combined income"), then up to 85 percent of your SSDI becomes taxable. The thresholds are $25,000 for single filers and $32,000 for married couples filing jointly, and they have not changed since 1984.

Social Security sends you a Form SSA-1099 each January showing how much you received in the prior year. You use that figure to calculate whether any of your benefit is taxable. You do not have to file a tax return at all if your income falls below the standard deduction for your filing status—but if you have other income, you may need to file even if you owe no tax, because that is how you report the other income correctly.

Key Takeaways

  • SSDI is only taxable if your combined income (half your benefit plus all other income) exceeds $25,000 for single filers or $32,000 for married couples filing jointly.
  • Most people receiving only SSDI pay no federal income tax because their combined income stays below the threshold.
  • You receive a Form SSA-1099 each January showing your total SSDI for the prior year; use that to calculate your combined income.
  • If you have wages, self-employment income, or retirement account distributions, you must include half your SSDI in the calculation even if none of it ends up being taxable.
  • State income tax treatment of SSDI varies; some states tax it, others do not, regardless of federal rules.

How the IRS calculates taxable SSDI

The calculation has two steps. First, you find your combined income: add half of your annual SSDI benefit to all your other income for the year (wages, self-employment, interest, dividends, distributions from IRAs or 401(k)s, and other sources). Do not include certain items like Supplemental Security Income (SSI), workers' compensation, or nontaxable interest.

Second, you compare that combined income to the threshold for your filing status. If it is $25,000 or less (single) or $32,000 or less (married filing jointly), none of your SSDI is taxable. If it exceeds the threshold, you move to the taxability formula. The formula is complex, but the IRS Worksheet in the instructions to Form 1040 walks you through it line by line. In practice, the amount of SSDI that becomes taxable ranges from just over zero to a maximum of 85 percent of your benefit.

Example: You are single and received $14,000 in SSDI for the year. You also earned $15,000 in wages. Your combined income is $7,000 (half of $14,000) plus $15,000, which equals $22,000. Because $22,000 is below $25,000, none of your SSDI is taxable. You would report the $15,000 in wages on your tax return, but not the SSDI.

Another example: You are single and received $14,000 in SSDI and $20,000 in wages. Your combined income is $7,000 plus $20,000, which equals $27,000. Because $27,000 exceeds $25,000, some of your SSDI is taxable. Using the IRS worksheet, you would find that roughly $1,500 of your SSDI becomes taxable income. You would report both the wages and the taxable portion of SSDI on your return.

When you must file a tax return even if you owe no tax

You are required to file a federal income 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 single filers under 65 and $18,350 for single filers 65 and older. For married couples filing jointly, it is $29,200 under 65 and $30,750 if one spouse is 65 or older.

If you have wages or self-employment income, those count toward the standard deduction threshold. SSDI does not count toward the threshold itself, but it may become taxable once you file. This means you could have $10,000 in wages and $20,000 in SSDI, owe no tax (because $10,000 is below the standard deduction), but still need to file a return to report the wages correctly and calculate whether any SSDI is taxable.

Even if you owe no tax, filing a return may be worth doing if you are may have access to to refundable tax credits like the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit. These credits can result in a refund even if you owe no tax. Many people with SSDI and part-time work may have access to for EITC.

SSDI and retirement account distributions

If you receive distributions from a traditional IRA, 401(k), or other retirement account, those distributions count as income for the combined income calculation. This can push you over the threshold and make some of your SSDI taxable even if you have no wages.

Roth IRA distributions are treated differently: may have access to distributions (those taken after age 59½ and at least five years after your first Roth contribution) are not counted in combined income. Non-may have access to Roth distributions are counted. This is one reason some people with SSDI consider converting traditional IRA funds to a Roth, though that conversion itself creates taxable income in the year it occurs.

If you are under full retirement age and still working, you also need to know about the SSDI earnings test. If your wages exceed a certain amount ($23,400 in 2024, though this figure changes yearly), Social Security will reduce your benefit by $1 for every $2 you earn above that limit. This reduction happens before you file taxes, so your Form SSA-1099 will already reflect the reduced amount. The earnings test does not explore once you reach full retirement age.

State income tax on SSDI

Federal rules do not bind the states. Some states do not tax SSDI at all, regardless of your income level. Others follow federal rules and tax SSDI the same way the IRS does. A few states have their own thresholds or formulas that differ from federal law.

States that do not tax SSDI include Alaska, Florida, Illinois, Iowa, Kentucky, Louisiana, Massachusetts, Michigan, Mississippi, Missouri, Nevada, New Hampshire, New Mexico, North Carolina, Ohio, Pennsylvania, South Dakota, Tennessee, Texas, Washington, Wisconsin, and Wyoming. This list can change, so check your state's revenue or taxation website or ask a tax professional in your state.

If you live in a state that does tax SSDI, you will need to file a state return and calculate your state taxable income separately. Some states use the federal combined income threshold; others do not. Your state tax return instructions will explain the rules for your state.

What to do with your Form SSA-1099

Social Security mails Form SSA-1099 to you by January 31 each year. It shows the total SSDI you received in the prior calendar year. Keep this form with your tax records. You will need it to complete the IRS worksheet that calculates how much of your SSDI is taxable.

If you file taxes yourself using tax software, you will enter the amount from Box 5 of the Form SSA-1099 into the SSDI field. The software will then walk you through the calculation. If you use a tax professional, bring the Form SSA-1099 along with documentation of any other income (W-2s, 1099s, bank statements showing interest, etc.).

If you do not receive a Form SSA-1099 by early February, contact Social Security at 1-800-772-1213 or visit your local Social Security office. You can also create a my Social Security account online and view your Form SSA-1099 there before it arrives in the mail.

SSDI, Medicare, and Medicaid do not affect your tax filing

Receiving Medicare or Medicaid does not change whether you owe tax on SSDI. These are separate programs. Medicare is health insurance you become may have access to to after receiving SSDI for 24 months. Medicaid is a means-tested program that varies by state. Neither one is counted as income for tax purposes, and neither one affects the combined income calculation.

However, if you have income high enough to make some of your SSDI taxable, that same income might affect your Medicaid status in some states. Medicaid has its own income limits, which are usually lower than the SSDI taxability thresholds. If you are concerned about losing Medicaid because of work income, speak with a benefits planner at your state vocational rehabilitation agency or a work incentives planning and information (WIPA) project before you start or increase work.

Frequently Asked Questions

What if I received SSDI for only part of the year?

Your Form SSA-1099 will show only the months you received a benefit. You use that actual amount in the combined income calculation. If you started SSDI in June, for example, you will have six months of benefits on the form, not twelve.

Do I have to pay estimated taxes on SSDI?

No. SSDI is not subject to estimated tax requirements. If you have other income (wages or self-employment) that requires estimated taxes, you calculate those based on that income alone, not on SSDI.

Can I have taxes withheld from my SSDI check?

Yes. You can request federal income tax withholding on your SSDI benefit by completing Form W-4V and submitting it to Social Security. This is optional but can help if you know some of your SSDI will be taxable and you want to avoid a tax bill at filing time.

What happens if I file my taxes late?

If you owe tax on SSDI and file late, you may owe penalties and interest. If you cannot file by April 15, you can request an extension by filing Form 4868, which gives you until October 15. If you do not owe tax, there is no penalty for filing late, but you may lose a refund if you wait more than three years.

Does SSDI count as income for other benefits or programs?

SSDI is counted as income for some means-tested programs (like SNAP or housing information) but not for others. It does not count toward the standard deduction for tax purposes, but it does count toward combined income for the SSDI taxability calculation. Check the rules for any other program you are in.
