How to Report SSDI on Your Tax Return

 If you receive Social Security Disability Insurance (SSDI), this guide explains how to report SSDI on your tax return and calculate whether any of your benefits are taxable. The amount you received isn’t automatically taxable income. You might not even owe taxes. 

This article explains how to calculate if any of those benefits are taxable and report your SSDI. If you paid some SSDI benefits back to the Social Security Administration (SSA) or received back pay for an earlier year, you may need to follow special tax instructions. We explain both situations below.

How to Calculate if Your SSDI Is Taxable

SSDI is not always taxed. The calculation uses your filing status, adjusted gross income, and other amounts on the IRS worksheet. Use the Internal Revenue Service’s (IRS) Social Security Benefits Worksheet to calculate how much of your SSDI is taxable. 

The worksheet uses your adjusted gross income, half of your SSDI payments, and other amounts before applying any adjustments that apply to you. 

Depending on your combined income, you may not owe federal income tax on those benefits, or you could owe taxes on as much as 85% of your SSDI income. 

Let’s look at the income brackets that apply to your provisional income and determine how much of your SSDI is taxed. 

How Much of Your SSDI Can Be Taxed?

The taxable amount of your SSDI depends on your filing status and combined income from the worksheet. If you are married and file jointly, combine your income with your spouse’s income when completing the worksheet. If your spouse also receives SSDI or other Social Security benefits, include those benefits too.

If you are married filing separately and lived with your spouse at any time during the year, the income threshold is $0. Up to 85% of your SSDI may be taxable.

The 50% and 85% figures are not tax rates. They are the maximum portions of your SSDI that can be counted as taxable Social Security benefits. 

This table shows income ranges that apply for federal taxes.

Filing Status Total Income How Much of Your SSDI Might Be Taxable?
Single, head of household, or qualifying surviving spouse $25,000 or less None
$25,001 to $34,000 Up to 50%
More than $34,000 Up to 85%
Married filing jointly $32,000 or less None
$32,001 to $44,000 Up to 50%
More than $44,000 Up to 85%
Married filing separately and lived apart from your spouse all year $25,000 or less None
$25,001 to $34,000 Up to 50%
More than $34,000 Up to 85%

How to Report SSDI on Your Tax Return

Your Social Security Benefit Statement, Form SSA-1099, is the main SSDI tax form and provides the information you need to report your SSDI. The SSA sends this statement in January. You should receive it by January 31. You can also view, download, or print it through your online Social Security account starting Feb. 1. You can also request a replacement 1099 by calling the SSA.

Supplemental Security Income (SSI) is not taxable, so the SSA doesn’t issue an SSA-1099 for SSI payments.

Three boxes on this SSDI tax form matter most. 

Box What It Shows
3 Total SSDI benefits paid during the year
4 SSDI benefits you repaid to the SSA
5 Net SSDI benefits after repayments

‍

When you file:

  • Enter the amount from Box 5 on Form 1040 or 1040-SR, line 6a.
  • Enter the taxable amount you calculated on the Social Security Benefits Worksheet on line 6b.
  • If none of your SSDI is taxable, enter zero on line 6b.

Line 6a reports your net SSDI benefits. Line 6b reports your taxable Social Security benefits. 

The line numbers in this article reflect the Form 1040 from 2025 and previous years. IRS forms can change, so check the current Form 1040 or 1040-SR instructions when you file.

If You Repaid SSDI Benefits

Check Box 4 of your SSA-1099 if you repaid SSDI benefits. If the amount you repaid is more than the SSDI benefits you received for the year, the usual worksheet does not apply.

In that situation, you may be able to claim a tax deduction or credit. IRS Publication 915 explains how to calculate the deduction or credit. You might want help from a tax preparer because the calculation is different from the standard SSDI tax calculation. See options for free help below.

How to Report SSDI Back Pay From an Earlier Year

SSDI back pay can include benefits for an earlier year. You report SSDI back pay on the current year’s tax return, even if some of the back pay is for an earlier year. You don’t amend your earlier tax return.

If part of your SSDI back pay is for an earlier year, the lump-sum election lets you use that earlier year’s income to calculate the taxable part of those benefits.

Complete the lump-sum worksheets in IRS Publication 915. Then compare that taxable amount with the amount from the regular calculation.

If the lump-sum election gives you a lower taxable amount, use that result and check the lump-sum election box on Form 1040 or 1040-SR.

If you need help with the worksheets, contact a qualified tax preparer.

When to Get Tax Help

If you are not sure which IRS worksheet to use or think your SSA-1099 is incorrect, you may want help.

Contact the SSA if you think the benefit information is wrong on your 1099. For more questions about how to report SSDI on your tax return, use IRS guidance or ask a qualified tax preparer.
