You may not have to report SSDI on your taxes, but the IRS requires you to determine this yourself

Social Security Disability Insurance (SSDI) is taxable income only if your combined income exceeds a threshold set by the IRS. Combined income includes your SSDI payments plus half of those payments plus any other income you receive—wages, interest, pensions, or tax-exempt interest. If your combined income stays below the threshold, you owe nothing on your SSDI. If it exceeds the threshold, you may owe federal income tax on up to 85 percent of your SSDI benefits.

The IRS does not automatically tell you whether you must report SSDI. You calculate it yourself using IRS worksheets, or you can contact Social Security to request a calculation. Many people with SSDI and no other income owe no tax at all. Others with wages or pensions alongside SSDI will owe tax on a portion of their benefits. The threshold does not adjust for inflation, so the same dollar amount has applied since 1984.

Key Takeaways

  • You must report SSDI on your tax return only if your combined income—SSDI plus half your SSDI plus other income—exceeds $25,000 (single filer) or $32,000 (married filing jointly).
  • Social Security sends you a Form SSA-1099 each January showing your SSDI payments for the prior year, which you use to calculate whether you owe tax.
  • If you have wages, pensions, or investment income alongside SSDI, you are more likely to owe tax on a portion of your benefits.
  • The IRS provides a worksheet in Publication 915 to calculate taxable SSDI; you can also call Social Security to request they do the calculation for you.

How the IRS calculates whether your SSDI is taxable

The IRS uses a two-tier system. Your combined income is calculated as: your adjusted gross income (AGI) plus nontaxable interest plus half your SSDI benefits. If your combined income is below $25,000 (single filer) or $32,000 (married filing jointly), none of your SSDI is taxable. If it exceeds that first threshold, you move to the second tier.

In the second tier, you may owe tax on up to 50 percent of your benefits if your combined income is between $25,000 and $34,000 (single) or $32,000 and $44,000 (married filing jointly). If your combined income exceeds $34,000 (single) or $44,000 (married filing jointly), you may owe tax on up to 85 percent of your benefits. The actual amount depends on how far above the threshold you are.

Example: You are single, receive $1,500 per month in SSDI ($18,000 per year), and have $10,000 in wages. Your combined income is $10,000 plus $9,000 (half your SSDI) = $19,000. You are below the $25,000 threshold, so none of your SSDI is taxable. You report only the $10,000 in wages.

Example: You are single, receive $1,500 per month in SSDI ($18,000 per year), and have $20,000 in wages. Your combined income is $20,000 plus $9,000 = $29,000. You are above the first threshold but below the second. You may owe tax on up to 50 percent of your SSDI. The exact amount requires the IRS worksheet in Publication 915.

What document you receive and when

Social Security mails you a Form SSA-1099 each January for the prior calendar year. This form shows the total SSDI you received in that year. You use this amount to calculate your combined income and determine whether any of your benefits are taxable. If you do not receive the form by early February, you can request it from Social Security by phone or online.

You do not receive a Form 1099 for SSDI the way you do for wages or interest. The SSA-1099 is informational only—it tells you what you received, but the IRS does not receive a copy automatically. You are responsible for reporting the taxable portion on your Form 1040 or 1040-SR.

How to report taxable SSDI on your return

If you determine that part of your SSDI is taxable, you report it on line 5b of Form 1040 or 1040-SR (the standard federal income tax return). You also complete Worksheet 1 or Worksheet 2 in IRS Publication 915 to calculate the exact taxable amount. These worksheets walk you through the combined income calculation step by step.

If you use tax software (TurboTax, H&R Block, TaxAct, or similar), the software will ask whether you received SSDI and will run the calculation for you. If you file by hand or with a tax preparer, bring your SSA-1099 and any other income documents, and tell them you received SSDI. A tax preparer can complete the worksheet for you.

You do not file a separate form or worksheet with the IRS—you straightforward report the taxable amount on line 5b of your return. Keep your own copy of the Publication 915 worksheet for your records.

When you may not owe tax even with SSDI

If SSDI is your only income, you almost certainly owe no federal income tax. The standard deduction for 2024 is $14,600 (single filer age 65 or older) or $29,200 (married filing jointly, both age 65 or older). Your SSDI would have to exceed these amounts for you to owe tax, and most people do not receive that much in SSDI annually.

You also owe no tax if your combined income falls below the first threshold ($25,000 single, $32,000 married filing jointly). This is true even if you have other income—wages, pensions, interest, or rental income—as long as the total combined income stays below the threshold.

Some states do not tax SSDI at all, regardless of your income level. Check your state tax rules or contact your state revenue department to confirm. If your state does not tax SSDI, you may owe no state income tax on your benefits even if you owe federal tax.

How to request Social Security calculate it for you

If you do not want to use the IRS worksheet, you can call Social Security and ask them to calculate whether your SSDI is taxable. They will ask for your other income (wages, pensions, interest, and any nontaxable interest) and will tell you whether you owe tax on your benefits and how much.

Call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) and say you want a tax calculation or tax information. Have your SSA-1099 and any other income documents ready. Social Security will provide the answer over the phone or can mail you a written calculation. This service is free and takes a few minutes.

You can also visit your local Social Security office in person if you prefer to discuss it face-to-face. Find your nearest office at ssa.gov/locator.

What happens if you do not report taxable SSDI

The IRS does not automatically know how much SSDI you received because Social Security does not report it to them. However, if you file a tax return and your reported income does not match Social Security's records, the IRS may send you a notice asking for the missing income. If you owe tax on SSDI and do not report it, you may face penalties and interest.

If you are unsure whether you owe tax, filing a return that includes the taxable portion of your SSDI is safer than omitting it. If you later find out you did not owe tax on that amount, you can file an amended return (Form 1040-X) to correct it. The IRS is more lenient with taxpayers who report too much income than those who report too little.

Frequently Asked Questions

Do I have to file a tax return if I only receive SSDI?

No, not unless your SSDI alone exceeds the standard deduction for your age and filing status. For 2024, that is $14,600 for a single filer age 65 or older. Most people receiving only SSDI do not file a return. However, if you have other income (wages, pensions, interest), you may need to file even if your SSDI is not taxable.

Does receiving SSDI affect my tax refund?

SSDI itself does not reduce your refund. Your refund depends on how much tax you paid through withholding or estimated payments and how much tax you owe based on your total income. If you have wages alongside SSDI, your employer withholds tax from your wages, which may result in a refund if you withheld more than you owed.

Can I claim SSDI as a dependent on someone else's return?

No. SSDI is not counted as income for dependent purposes. However, if someone else pays more than half your living expenses and you meet other dependent tests, they may be able to claim you as a dependent regardless of your SSDI. The rules are complex—consult a tax preparer if this applies to you.

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

Your SSA-1099 will show only the SSDI you received during the months you were may be able to access. Use that amount to calculate your combined income. If you started or stopped receiving SSDI mid-year, the calculation is the same—use the actual amount shown on your SSA-1099.

Do I need to report SSDI if I live outside the United States?

Yes, U.S. citizens and resident aliens must report SSDI on their federal tax return using the same rules, regardless of where they live. If you live in a foreign country, you may also owe tax to that country. Consult a tax professional familiar with expatriate tax rules.
