Whether you must report SSDI depends on your total income

You do not automatically have to report SSDI on your federal tax return just because you received it. Whether you report it depends on how much money you earned from work, how much you received from other sources, and your filing status. The Social Security Administration sends you a form called an SSA-1099 each January showing what you received in the previous year, but receiving that form does not automatically mean you owe taxes on it.

The key question is whether your combined income exceeds a certain threshold. Combined income includes your SSDI payments plus half of your SSDI plus any wages, interest, dividends, or other income you earned. If that combined total stays below the threshold for your filing status, you file a tax return only if you want to claim a refund. If it exceeds the threshold, you must file.

The thresholds are low—often between $12,000 and $25,000 depending on your age and filing status—but most people receiving SSDI alone do not reach them. The risk comes when you also have wages from work, retirement income, or investment income.

Key Takeaways

  • You report SSDI on your tax return only if your combined income (SSDI plus half of SSDI plus other income) exceeds the threshold for your filing status.
  • The Social Security Administration sends you an SSA-1099 in January, but that form arriving does not mean you must file taxes.
  • If you earned wages while receiving SSDI, you almost certainly must file a tax return even if SSDI itself is not taxable.
  • The IRS has a worksheet to calculate whether your SSDI is taxable; you can also contact the Social Security Administration or a tax preparer to confirm.

How the IRS calculates whether SSDI is taxable

The IRS uses a specific formula to determine the taxable portion of your SSDI. Start with your combined income: take half of your SSDI payments, add all your wages, interest, dividends, and other income, and add any tax-exempt interest (such as from municipal bonds). That total is your combined income.

Next, compare that combined income to two thresholds. If you are single and your combined income is under $25,000, none of your SSDI is taxable. If it is between $25,000 and $34,000, up to 50 percent of your SSDI may be taxable. If it exceeds $34,000, up to 85 percent may be taxable. The thresholds are different if you are married filing jointly ($32,000 and $44,000) or married filing separately (usually $0 and $9,000).

The IRS Pub. 915 contains a worksheet that walks you through the calculation step by step. Many tax preparation software programs also calculate this automatically when you enter your SSA-1099.

When you must file even if SSDI is not taxable

Even if none of your SSDI is taxable, you may still be required to file a tax return. The rule depends on your other income. If you earned wages from work—even part-time work—you must file if those wages exceed the standard deduction for your age and filing status. For 2024, the standard deduction is $14,600 for a single person under 65 and $17,550 if you are 65 or older.

This matters because many people receiving SSDI also work. If you earned $15,000 in wages and received $20,000 in SSDI, your combined income is well below the SSDI taxability threshold, but you still must file because your wages alone exceed the standard deduction.

You may also want to file even if you are not required to, because you might be owed a refund. If your employer withheld taxes from your wages, filing allows you to claim that refund.

What happens if you do not report SSDI when you should

If your SSDI is taxable and you do not report it, the IRS may assess penalties and interest on the unpaid tax. The Social Security Administration reports SSDI payments to the IRS, so the agency knows what you received. If your tax return shows income that does not match what the IRS received from Social Security, the IRS will likely contact you.

The penalty for failing to file a required return is usually 5 percent of the unpaid tax per month, up to 25 percent total. Interest accrues on top of that. If you discover you should have filed in a previous year, you can file an amended return (Form 1040-X) and pay what you owe; the IRS often waives penalties if you file the amended return voluntarily.

The safest approach is to file a return whenever you are unsure. Filing when you are not required costs nothing and protects you from penalties.

Using the IRS worksheet to check your own situation

The IRS Pub. 915 contains a worksheet you can complete yourself to determine whether your SSDI is taxable. You will need your SSA-1099 (which shows your SSDI for the year), your W-2 forms or 1099 forms showing other income, and information about any tax-exempt interest you received.

The worksheet takes about 10 minutes if you have all your documents. It walks you through adding half your SSDI to your other income, comparing that total to the thresholds, and calculating the taxable portion if any. If the result shows that none of your SSDI is taxable, you know you do not owe tax on it—though you may still need to file for other reasons.

If the worksheet shows that some of your SSDI is taxable, you can enter that amount on line 5b of your Form 1040 when you file. Many tax preparation programs do this calculation for you automatically.

Getting help from Social Security or a tax preparer

If you do not want to do the calculation yourself, you have two options. The Social Security Administration can answer questions about your SSDI and help you understand how much you received, though they do not provide tax information. You can call 1-800-772-1213 or visit your local Social Security office.

A tax preparer or certified public accountant (CPA) can review your situation and tell you whether you must file and whether your SSDI is taxable. Many offer free or low-cost preparation if your income is below a certain level through the IRS Free File program. AARP also offers free tax preparation for people 60 and older through their Tax-Aide program.

Frequently Asked Questions

Do I have to report SSDI if I did not work that year?

Not necessarily. If SSDI was your only income and it was under $25,000 (or the threshold for your filing status), you do not have to report it. However, if you want to claim a refund of taxes withheld from other sources, you should file anyway.

What if I worked part of the year and received SSDI the rest?

You must file if your wages exceed the standard deduction for your age. Your SSDI and wages are added together to determine whether SSDI itself is taxable, but the wages alone may require you to file.

Can I owe taxes on SSDI if I am below the income threshold?

No. If your combined income is below the threshold for your filing status, none of your SSDI is taxable. You may still owe taxes on other income, but not on the SSDI itself.

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

The SSA-1099 will show only the months you received it. Use that amount (not an annualized figure) when calculating your combined income and checking the thresholds.

Do I need to keep my SSA-1099 if I do not file a return?

Yes. Keep it with your tax records for at least three years in case the IRS asks questions about your income. You do not need to send it to the IRS unless you file a return.
