When SSDI Becomes Taxable Income

If you received SSDI benefits in a tax year and also had other income—wages, interest, pensions, or self-employment earnings—the IRS may count part or all of your benefits as taxable income. The calculation depends on your "combined income," a formula that adds your adjusted gross income, nontaxable interest, and half your SSDI benefits. If that total exceeds a threshold ($25,000 for single filers, $32,000 for married filing jointly), you owe federal income tax on up to 85 percent of your benefits.

Many people with SSDI don't realize they owe taxes until after the year ends, because benefits are not withheld automatically. If you had taxes withheld from other income sources but not from SSDI, you may have overpaid and be may have access to to a refund. The refund process is the same as for any other overpayment: you file a tax return showing what you earned and what was withheld, and the IRS sends you the difference.

Key Takeaways

  • You file a tax return using Form 1040 and Schedule 1 (or Form 1040-SR if you are 65 or older), reporting your SSDI income using the combined income formula, not the benefit amount itself.
  • If your employer or bank withheld federal income tax from wages or interest, but you owe less tax than what was withheld, you receive a refund for the overpayment.
  • The IRS does not send you a 1099 for SSDI benefits; you must calculate the taxable portion yourself or use a tax preparer, and keep your SSA-1099 form from Social Security.
  • If you cannot afford to pay taxes owed on SSDI, you can request a payment plan or offer in compromise through the IRS, but these do not reduce the amount owed.
  • Some states do not tax SSDI benefits even if the federal government does, so you may owe federal tax but not state tax.

How the Taxable Amount Is Calculated

The IRS uses a two-tier system to determine how much of your SSDI is taxable. First, add your adjusted gross income (wages, self-employment income, taxable pensions, taxable interest, and other sources), plus any nontaxable interest (such as municipal bond interest), plus half your SSDI benefits. This is your combined income.

If your combined income is below the threshold ($25,000 single, $32,000 married filing jointly), none of your SSDI is taxable. If it exceeds the threshold but is below a second tier ($34,000 single, $44,000 married), up to 50 percent of your benefits above the threshold is taxable. If it exceeds the second tier, up to 85 percent of your benefits is taxable, plus 50 percent of the amount over the second tier.

Example: A single person receives $15,000 in SSDI and $20,000 in wages, with no other income. Combined income is $20,000 + (half of $15,000) = $27,500. This exceeds the $25,000 threshold by $2,500. Up to 50 percent of the excess—$1,250—is taxable. So $1,250 of the $15,000 SSDI benefit is counted as income on the tax return.

Filing a Return to Claim a Refund

To claim a refund, you must file a federal income tax return even if you normally would not have to. Use Form 1040 (or Form 1040-SR if you are 65 or older). You will also need Schedule 1 to report the taxable portion of your SSDI benefits on line 5b.

Gather your SSA-1099 form from Social Security (sent in January), your W-2 forms from employers, and 1099 forms for any other income. If you had federal income tax withheld from wages or other sources, that amount appears on those forms. Calculate your taxable SSDI using the combined income formula, or ask a tax preparer to do it. Enter all income on the return, calculate your tax liability, and compare it to what was withheld. If more was withheld than you owe, the difference is your refund.

You can file on paper by mailing Form 1040 and supporting documents to your IRS service center, or file electronically using tax software or a tax preparer. The IRS typically processes refunds within 21 days of receiving an electronic return, or 4 to 6 weeks for a paper return. You can check the status of your refund on the IRS website using the "Where's My Refund?" tool.

What Documents You Need

Social Security sends you an SSA-1099 form each January showing the total SSDI benefits you received in the prior year. This is not the same as a 1099-MISC or 1099-NEC; it is specific to Social Security benefits. Keep this form with your tax records. If you did not receive one, you can request a replacement from your local Social Security office or online at ssa.gov.

Collect all W-2 forms from employers and 1099 forms for interest, dividends, self-employment income, or other sources. If you had federal income tax withheld from any of these, the withholding amount is shown in box 2 of the W-2 or the appropriate box of the 1099. You will also need proof of any nontaxable income—for example, a statement from your bank showing nontaxable interest from a municipal bond fund.

If you are filing with a tax preparer or using tax software, you can usually upload these documents or provide them in person. If you are filing on paper, attach a copy of your W-2 and 1099 forms to your return; do not attach the SSA-1099, but keep it for your records in case the IRS asks questions.

State Taxes and SSDI

Thirty-seven states do not tax SSDI benefits at all, regardless of your income level. These states are: Alabama, Alaska, Arizona, Arkansas, California, Colorado, Delaware, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Mississippi, Missouri, Montana, Nevada, New Hampshire, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, and Wyoming.

Thirteen states do tax SSDI benefits under certain conditions: Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The rules vary by state—some tax only benefits above a certain income threshold, others tax only a portion, and some have age-based exemptions. If you live in one of these states and owe state income tax, you will file a separate state return and may owe state tax even if you do not owe federal tax, or vice versa.

Check your state's tax authority website or ask a tax preparer about your state's rules. Some states allow you to request a refund of state taxes withheld from other income if you overpaid, just as the federal government does.

If You Owe Taxes Instead of Getting a Refund

If your combined income is high enough that your total tax liability exceeds what was withheld, you owe the IRS the difference. You can pay in full when you file, or request a payment plan. The IRS offers short-term plans (120 days or less) at no cost, and long-term installment agreements for larger amounts, which carry a setup fee and monthly interest.

If you cannot pay the full amount and cannot afford a payment plan, you can request an Offer in Compromise—a settlement for less than you owe. This is difficult to obtain and requires detailed financial documentation, but it is an option if you are experiencing genuine hardship. Contact the IRS at 1-800-829-1040 to discuss your situation, or work with a tax professional or IRS-certified representative.

Do not ignore a tax bill. The IRS charges penalties and interest on unpaid taxes, and these accumulate quickly. Even a small payment toward what you owe stops the penalty from growing, and a payment plan prevents the IRS from placing a lien on your property or garnishing other income.

Frequently Asked Questions

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

No. If SSDI is your only income and you have no other income sources, none of your benefits are taxable and you do not have to file. However, if you had federal income tax withheld from other income (such as a part-time job or interest), you should file to claim a refund of that withholding.

What if I did not have taxes withheld from my wages—can I still get a refund?

A refund occurs only when you have overpaid taxes—that is, when more was withheld than you actually owe. If no taxes were withheld from your wages and you owe taxes on your SSDI, you owe the IRS; you do not receive a refund. You can request a payment plan to spread the payment over time.

Can I amend a return I filed in a prior year to claim a refund I missed?

Yes. You can file Form 1040-X (Amended U.S. Individual Income Tax Return) for any of the past three years. If you discover you overpaid taxes in a prior year, file the amended return with the correct calculation, and the IRS will send you a refund. The IRS typically processes amended returns in 16 weeks.

Will claiming a tax refund affect my SSDI benefits?

No. Filing a tax return or receiving a tax refund does not change your SSDI benefit amount or your may be able to access. The IRS and Social Security are separate agencies and do not share information about tax refunds.

What if I cannot calculate the taxable portion of my SSDI myself?

You can use tax software (many offer free versions for lower incomes), contact a tax preparer or CPA, or visit a free tax clinic run by the IRS Volunteer Income Tax information (VITA) program. VITA clinics are free and available in most communities; find one at irs.gov or by calling 211.
