You may still need to file taxes even though you receive SSDI

Social Security Disability Insurance (SSDI) counts as income for tax purposes, which means you might owe federal taxes on it — even though you didn't pay income tax to receive the benefit. Whether you actually have to file depends on how much SSDI you got, whether you had other income, and your filing status. The Internal Revenue Service (IRS) has specific rules about when SSDI becomes taxable, and those rules are different from the ones that explore to regular wages.

The key number is called your "combined income." The IRS calculates this by taking your adjusted gross income, plus any non-taxable interest, plus half of your SSDI benefits. If that number exceeds a certain threshold — which depends on whether you're single, married filing jointly, or married filing separately — then part or all of your SSDI becomes taxable. For 2024, those thresholds were $25,000 for single filers and $32,000 for married couples filing jointly, though these amounts can change year to year.

Key Takeaways

  • You calculate whether SSDI is taxable using "combined income," which includes half your SSDI benefits plus your other income.
  • If you have little or no other income, your SSDI is usually not taxable, and you may not need to file at all.
  • The IRS sends Form SSA-1099 each January showing your SSDI payments from the previous year.
  • You report SSDI on your tax return using Form 1040 and the Social Security Worksheet, which is included in the IRS instructions.
  • If you owe taxes on SSDI, you can arrange to have the IRS withhold taxes from your monthly benefit instead of paying a lump sum.

Understanding combined income and the taxability threshold

The IRS does not tax all of your SSDI the same way. Instead, it uses a two-tier system. If your combined income is below the first threshold ($25,000 single, $32,000 married filing jointly in 2024), none of your SSDI is taxable. If your combined income is between the first and second threshold ($34,000 single, $44,000 married filing jointly in 2024), up to 50 percent of your benefits may be taxable. If your combined income exceeds the second threshold, up to 85 percent of your benefits may be taxable.

Combined income is not the same as your total income. It is calculated as: your adjusted gross income (wages, self-employment income, interest, dividends, and other sources) plus any tax-exempt interest (such as interest from municipal bonds) plus half of your SSDI benefits. This means that even if you have no other income at all, half your SSDI counts toward the threshold. For most people receiving SSDI with little or no other income, this means the threshold is not crossed and no tax is owed.

The thresholds do not adjust for inflation every year — Congress sets them — so it is worth checking the current year's amounts on the IRS website or in the instructions to Form 1040 before you file.

Getting your SSDI income information from Form SSA-1099

Each January, the Social Security Administration sends you a Form SSA-1099 showing how much SSDI you received in the previous calendar year. This form arrives by mail to the address on file with Social Security. The form shows the total amount paid to you in box 5. You will need this number to calculate your combined income and to fill out your tax return.

If you did not receive a Form SSA-1099 by early February, you can request one by calling Social Security at 1-800-772-1213 or by visiting your local Social Security office. You can also create a my Social Security account online at ssa.gov to view your benefit payment history, which shows the same information.

Keep your Form SSA-1099 with your tax records. You do not send it to the IRS with your return, but you do need it to fill out the Social Security Worksheet that determines how much of your SSDI is taxable.

Using the Social Security Worksheet to calculate taxable SSDI

The IRS provides a worksheet specifically for calculating how much of your SSDI is taxable. This worksheet is included in the instructions to Form 1040, which you can read free from irs.gov. The worksheet walks you through the combined income calculation step by step and tells you whether any of your benefits are taxable and, if so, how much.

You do not file the worksheet itself with the IRS — it is a working document. Instead, you use it to figure out the number you will enter on your Form 1040. The worksheet requires you to list your adjusted gross income, any tax-exempt interest, and half your SSDI benefits, then compare that total to the IRS thresholds for your filing status.

If you have other income sources (wages, self-employment income, interest, dividends, rental income, or pensions), the worksheet becomes more important because those sources increase your combined income and may push you over the threshold. If you have no other income and your SSDI is your only source of money, you can often skip the worksheet because your combined income will be below the threshold.

Reporting SSDI on Form 1040

When you file your federal tax return, you report SSDI on Form 1040, the main individual income tax form. The form has a line specifically for Social Security benefits. You enter the total amount from your Form SSA-1099 on this line, then use the Social Security Worksheet to determine how much is taxable. The taxable amount goes on another line in the income section of the form.

If none of your SSDI is taxable, you still enter the total amount on the Social Security benefits line, but the taxable amount line will be zero. This is normal and does not trigger any issues with the IRS. Many people who receive SSDI file this way every year.

If you use tax software to file (such as TurboTax, H&R Block, or the IRS Free File program), the software will ask you about your SSDI and will run the Social Security Worksheet for you automatically. If you file by hand or work with a tax preparer, make sure you have your Form SSA-1099 and the current year's Form 1040 instructions with the worksheet included.

Deciding whether you need to file at all

Not everyone who receives SSDI has to file a tax return. The IRS has a filing requirement threshold — a minimum amount of income you must have before filing becomes mandatory. For 2024, that threshold was $14,600 for a single person and $29,200 for a married couple filing jointly. These amounts include SSDI counted as income.

If your only income is SSDI and your combined income is below the threshold for your filing status, you are not required to file. However, you may want to file anyway if you are due a refund — for example, if you had taxes withheld from other income or if you are due the Earned Income Tax Credit or another refundable credit.

To know for certain whether you must file, use the IRS Interactive Tax Assistant tool on irs.gov, which asks questions about your income and filing status and tells you whether filing is required. You can also call the IRS at 1-800-829-1040 for help.

Arranging tax withholding from your SSDI benefit

If you owe taxes on your SSDI, you have two options: pay the tax when you file your return, or have the IRS withhold taxes from your monthly SSDI payment throughout the year. Withholding spreads the cost across 12 months instead of requiring one lump-sum payment, which many people find easier to manage.

To set up withholding, you fill out Form W-4V (Voluntary Withholding Request) and send it to your local Social Security office or mail it to the address listed on the form. You choose a withholding rate — typically 7, 10, 15, or 25 percent of your monthly benefit. Social Security will then reduce your monthly payment by that amount and send the withheld money to the IRS.

You can change or stop withholding at any time by submitting a new Form W-4V. If you change jobs, move, or your income changes significantly, you may want to adjust your withholding to avoid owing a large amount at tax time or having too much withheld.

What happens if you do not file when you should

If you owe taxes on your SSDI and do not file a return, the IRS may eventually contact you. However, because SSDI is reported to the IRS by Social Security, the IRS knows you received it. If your income was high enough that you should have filed, the IRS may send you a notice asking you to file or explaining that you owe taxes.

Filing late is better than not filing at all. If you owe taxes, filing late means you will owe penalties and interest on top of the tax itself. If you are due a refund, there is no penalty for filing late, but you can only claim a refund for the past three years — after that, the money goes to the government.

If you are unsure whether you should have filed in past years, you can contact the IRS at 1-800-829-1040 or visit your nearest IRS office. The IRS can tell you which years you should have filed and help you get caught up.

Frequently Asked Questions

Do I have to file taxes if SSDI is my only income?

Not necessarily. If your only income is SSDI and your combined income is below the filing threshold for your status (around $14,600 for single filers in 2024), you are not required to file. However, if you had other income or taxes withheld, filing may get you a refund.

What if I have a job and receive SSDI?

Your wages plus half your SSDI count toward your combined income. This often pushes you over the threshold, making part of your SSDI taxable. You must report both your wages and your SSDI on your tax return. The Social Security Worksheet will show you how much of your SSDI is taxable given your total income.

Can I file my taxes online if I receive SSDI?

Yes. Tax software programs like TurboTax and H&R Block handle SSDI automatically. The IRS also offers free filing through its Free File program if your income is below a certain level. All of these options include the Social Security Worksheet built in.

What if I made a mistake on a previous year's return?

You can file an amended return using Form 1040-X for any of the past three years. If you owe additional tax, you will owe interest and possibly penalties. If you are due a refund, file the amended return as soon as you notice the error to claim it.

Does filing taxes affect my SSDI benefits?

No. Filing a tax return or owing taxes does not change your SSDI payment amount. SSDI is not means-tested, meaning your benefits do not go down based on how much money you have or earn. However, if you work, your earnings may affect your benefits under different Social Security rules.
