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 what you receive from Social Security. The IRS counts half your SSDI benefit plus all your other income (wages, interest, pensions, rental income) to determine if you cross the tax threshold. For most SSDI recipients, especially those with no other income, the answer is no tax owed.

The threshold is low: $25,000 for a single filer, $32,000 for married filing jointly. If your combined income stays below that line, you file a tax return only if required for other reasons—but you do not owe tax on the SSDI itself. If you cross the threshold, you may owe tax on up to 85 percent of your benefit, depending on how far over you go.

State taxes are separate. Fourteen states tax SSDI benefits under their own rules: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The rules in each state differ from federal rules, so you may owe state tax even if you owe nothing to the IRS, or vice versa.

Key Takeaways

  • You calculate combined income by adding half your SSDI to all other income sources; if the total stays 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 50 percent of your benefit at the first tier, or up to 85 percent at the second tier, depending on how much you exceed the limit.
  • Fourteen states tax SSDI under their own rules, and state thresholds and percentages differ from federal rules.
  • You receive a Form SSA-1099 each January showing your SSDI for the prior year; use this to calculate combined income and determine whether you must file a return.
  • If you work and earn wages, those wages count toward combined income and can push you over the threshold even if your SSDI alone would not.

How the IRS calculates combined income

The IRS formula is specific. Take half of your SSDI benefit for the year. Add every dollar of other income: W-2 wages, self-employment income, taxable interest, dividends, capital gains, pension distributions, rental income, and certain other sources. The total is your combined income.

Example: You receive $14,000 in SSDI and earn $15,000 in wages. Half your SSDI is $7,000. Combined income is $7,000 + $15,000 = $22,000. You are below the $25,000 threshold, so you owe no federal tax on the SSDI. You still owe income tax on the $15,000 in wages, calculated normally.

Some income does not count. Supplemental Security Income (SSI) does not count. Railroad Retirement benefits do not count. Veterans benefits do not count. Gifts and inheritances do not count. The key is whether the IRS treats it as taxable income on a 1040 form.

The two-tier tax structure for SSDI

If your combined income exceeds the threshold, the tax owed is not a flat percentage. The IRS uses two tiers. The first tier applies to combined income between the threshold and $9,000 above it (for single filers; $12,000 for married filing jointly). In this tier, you owe tax on up to 50 percent of your SSDI benefit.

The second tier applies to combined income above $34,000 (single) or $44,000 (married filing jointly). In this tier, you owe tax on up to 85 percent of your SSDI benefit. The actual percentage depends on how far above the threshold you go.

Example: You are single with $14,000 in SSDI and $20,000 in wages. Combined income is $7,000 + $20,000 = $27,000. You are $2,000 over the $25,000 threshold. You calculate tax on the lesser of (a) 50 percent of $14,000 = $7,000, or (b) 50 percent of the $2,000 overage = $1,000. You owe tax on $1,000 of your SSDI. The remaining $13,000 of SSDI is not taxable.

State taxes on SSDI

Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia all tax SSDI benefits. Two additional states—Illinois and Mississippi—tax SSDI only in specific circumstances (Illinois exempts it for most filers; Mississippi taxes it only if you also receive other retirement income).

State thresholds and tax rates do not match federal rules. Colorado, for instance, exempts SSDI entirely for residents over 55. Connecticut taxes SSDI the same way the IRS does. Kansas taxes it as regular income with no special threshold. You must check your state's specific rules or contact your state tax authority.

If you live in a state that taxes SSDI and your income is high enough to trigger state tax, you will owe state tax separately from any federal tax. Some states allow a credit for federal tax paid on SSDI; others do not.

What to do with your SSA-1099 form

Each January, the Social Security Administration mails you a Form SSA-1099 showing your SSDI for the prior year. This is your official record of benefits received. Use this form to calculate combined income and determine whether you must file a federal return.

If you are not required to file a return (because your income is too low), you do not need to do anything with the SSA-1099. Keep it for your records. If you are required to file or choose to file, attach the SSA-1099 to your return and report the SSDI on line 5b of Form 1040.

If you did not receive an SSA-1099 by early February, contact Social Security at 1-800-772-1213 or visit ssa.gov to request a replacement. Do not estimate your benefit amount; use the official figure from the form.

SSDI and Medicare premiums

SSDI itself does not affect your Medicare premiums. However, if you have other income that pushes your combined income above certain thresholds, your Medicare Part B and Part D premiums may increase. These thresholds are different from the SSDI tax thresholds and are based on your modified adjusted gross income (MAGI) from two years prior.

For 2024, if your MAGI exceeds $97,000 (single) or $194,000 (married filing jointly), your Part B premium rises. The increase is called an Income-Related Monthly Adjustment Amount (IRMAA). This is separate from income tax but is another reason to track your combined income carefully.

Work incentives and SSDI taxation

If you work while receiving SSDI, your wages count toward combined income and can push you into taxable territory. However, Social Security offers work incentives that can reduce your SSDI benefit without eliminating it, which may lower your combined income and your tax liability.

The Plan to Achieve Self-Support (PASS) allows you to set aside income and resources for a work goal without affecting your SSDI. The Impairment Related Work Expenses (IRWE) deduction lets you subtract certain disability-related work costs from your earnings before Social Security counts them. These tools can help you keep combined income below the tax threshold.

If you are working or considering work, contact your local Social Security office or a work incentives planning and information (WIPA) project to understand how your earnings will affect both your SSDI and your tax liability.

Frequently Asked Questions

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

No, unless your combined income exceeds the threshold ($25,000 single, $32,000 married filing jointly) or you have other income that requires filing. If your only income is SSDI below the threshold, you have no filing requirement. However, if you are due a refund from taxes withheld on other income, filing gets you that refund.

What if I receive both SSDI and SSI?

SSI does not count toward combined income for SSDI tax purposes. Only the SSDI portion is included in the calculation. However, SSI itself is never taxable, and receiving both programs does not change the SSDI tax rules.

Can I have taxes withheld from my SSDI to avoid owing at tax time?

Yes. You can request federal income tax withholding on your SSDI by completing Form W-4V and submitting it to Social Security. You choose the withholding amount. This does not change whether you owe tax; it just spreads the payment across the year instead of owing a lump sum in April.

If I move to a different state, do I owe back taxes on SSDI?

No. You owe state tax only on SSDI received while you were a resident of that state. If you move from a state that taxes SSDI to one that does not, you owe no tax on benefits received after you move. Your state of residence on December 31 determines which state's rules explore for that tax year.

How do I know if my state taxes SSDI?

Contact your state's department of revenue or tax authority directly. You can also visit the IRS website, which lists states that tax SSDI. If your state does tax it, ask for the specific threshold and percentage, because they differ from federal rules.
