SSDI is generally not taxable, but some of it may be if your total income crosses a threshold

Social Security Disability Insurance (SSDI) payments are not automatically taxable income. However, if you have other income—from work, pensions, interest, or other sources—a portion of your SSDI may become taxable. The IRS uses a formula based on your "combined income," which includes half of your SSDI plus all other income you received that year.

Whether you actually owe tax on SSDI depends on two thresholds. If you are single and your combined income is under $25,000, none of your SSDI is taxable. If you are married filing jointly, the threshold is $32,000. Above those amounts, up to 50 percent of your SSDI becomes taxable; if your combined income is very high, up to 85 percent may be taxable. Many people with SSDI have no other income and pay no tax on their benefits.

Key Takeaways

  • SSDI is not taxable unless your combined income (half your SSDI plus all other income) exceeds $25,000 for single filers or $32,000 for married filers.
  • Combined income includes wages, self-employment income, pensions, interest, dividends, and certain other sources, but not Supplemental Security Income (SSI).
  • If you owe tax on SSDI, you can pay it when you file your return or request that the Social Security Administration withhold taxes from your monthly payment.
  • You must file a tax return to determine whether any of your SSDI is taxable, even if you normally would not have to file.

How the IRS calculates whether your SSDI is taxable

The IRS uses a specific formula to determine taxable SSDI. Start by adding half of your SSDI benefits to all your other income for the year. This total is your "combined income." The IRS then compares this number to two thresholds.

For single filers, if combined income is $25,000 or less, no SSDI is taxable. If combined income is between $25,001 and $34,000, up to 50 percent of your SSDI becomes taxable. If combined income exceeds $34,000, up to 85 percent becomes taxable. For married couples filing jointly, the thresholds are $32,000 and $44,000. Married couples filing separately face much stricter rules and should consult a tax professional.

The actual calculation is complex because the IRS applies the thresholds in two tiers. Most people do not need to do this math themselves; the Social Security Administration provides a worksheet, and tax software can handle it. If you think you may owe tax on SSDI, a tax professional can walk you through the exact amount.

What counts as income for this calculation

Combined income includes wages from work, net self-employment income, interest, dividends, capital gains, rental income, and distributions from retirement accounts. It also includes certain pension income and distributions from IRAs. Crucially, it does not include Supplemental Security Income (SSI), which is a separate needs-based program.

If you are working while receiving SSDI, your wages count toward combined income. This means that even modest earnings can push you over the threshold and make some of your SSDI taxable. If you receive a pension from a job where you did not pay Social Security taxes—such as some government jobs—that pension counts as income for this purpose.

Tax-exempt interest (such as interest from municipal bonds) is included in the combined income calculation, even though it is not taxable. This is one reason why your combined income can be higher than your taxable income.

When you must file a tax return even if you have no tax liability

You must file a federal tax return if your gross income meets the filing threshold for your age and filing status, even if no tax is owed. For 2024, a single person under 65 must file if gross income is $14,600 or more. A single person 65 or older must file if gross income is $18,350 or more. These thresholds change each year.

If you receive SSDI and have other income, you should file a return to determine whether any SSDI is taxable. Filing also allows you to claim the Earned Income Tax Credit (EITC) if you work and have low income, or other credits you may be may have access to to. Even if you do not owe tax, filing can result in a refund.

The Social Security Administration does not withhold federal income tax from SSDI automatically. If you expect to owe tax, you can request voluntary withholding by completing Form W-4V and sending it to your local Social Security office. This spreads the tax burden across the year rather than requiring a lump-sum payment when you file.

How to report SSDI on your tax return

SSDI is reported on your federal tax return using Form 1040. The Social Security Administration sends you a Form SSA-1099 each January showing the total SSDI you received the previous year. You enter this amount on your return, and tax software or a tax professional will calculate whether any portion is taxable based on your other income.

You do not report SSDI on a separate form; it is part of the standard income calculation on Form 1040. If you use tax software, you will enter your SSA-1099 information when prompted, and the software will explore the IRS thresholds automatically. If you file by paper or work with a tax professional, they will handle the calculation.

Keep your SSA-1099 with your tax records. If you did not receive one by early February, contact the Social Security Administration at 1-800-772-1213 or visit your local office to request a replacement.

What to do if you cannot pay tax owed on SSDI

If you owe tax on SSDI but cannot pay the full amount when you file, you have options. You can request a payment plan through the IRS, which allows you to pay in installments over time. You can also request an offer in compromise if your financial situation is severe, though this is rarely granted.

Before filing, consider requesting voluntary withholding from your SSDI payment. Complete Form W-4V and submit it to your local Social Security office. You can request that 7, 10, 15, or 25 percent of your monthly benefit be withheld for taxes. This reduces your monthly payment but ensures you do not owe a large amount at tax time.

If you have already filed and owe money, contact the IRS at 1-800-829-1040 to discuss a payment arrangement. The IRS can set up a payment plan that fits your budget. Ignoring a tax bill can result in penalties and interest, so it is better to contact the IRS proactively.

State income tax on SSDI

Most states do not tax SSDI, but a few do. As of 2024, Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont tax some or all SSDI under certain conditions. The rules vary by state; some tax SSDI only if your total income exceeds a threshold, while others have different rules for residents over 65.

If you live in one of these states, check your state tax agency's website or contact them directly to understand your state's rules. Some states offer exemptions or deductions for SSDI that reduce or eliminate the tax. A state tax professional can help you determine what you owe.

You will receive a state tax form along with your federal forms if your state taxes SSDI. Follow your state's instructions for reporting SSDI on your state return. The calculation may differ from the federal calculation, so do not assume the same amount is taxable at both levels.

Frequently Asked Questions

If I work part-time and receive SSDI, will my wages make my SSDI taxable?

Possibly. Your wages count toward combined income. If your wages plus half your SSDI plus any other income exceeds $25,000 (or $32,000 if married filing jointly), some SSDI becomes taxable. For example, if you earn $15,000 and receive $12,000 in SSDI, your combined income is $21,000 ($15,000 + $6,000), which is below the threshold, so no SSDI is taxable.

Does SSI count as income for the SSDI tax calculation?

No. Supplemental Security Income (SSI) is not included in combined income for SSDI tax purposes. SSI is a separate, needs-based program, and the IRS treats it differently. Only SSDI, wages, pensions, interest, and similar income count.

Can I request that Social Security withhold taxes from my SSDI payment?

Yes. Complete Form W-4V and submit it to your local Social Security office or mail it to the address on the form. You can request withholding of 7, 10, 15, or 25 percent of your monthly benefit. You can change or stop withholding at any time by submitting a new form.

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

Your SSA-1099 will show only the SSDI you actually received. Use that amount in the combined income calculation. If you started or stopped receiving SSDI mid-year, the form reflects the correct total, and you calculate tax based on that amount.

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

No, not usually. If SSDI is your only income and it is below the filing threshold for your age and status, you do not have to file. However, filing may be beneficial if you are may have access to to tax credits like the Earned Income Tax Credit. Consider filing even if not required to see if you can claim a refund.
