You may have to file taxes even though you receive SSDI, and the answer depends on your total income and filing status

Social Security Disability Insurance (SSDI) payments themselves are usually not taxed as income. However, you still file a tax return if your other income — wages, interest, pensions — crosses certain thresholds. The IRS also taxes part of your SSDI in specific situations: when your "combined income" (SSDI plus half your SSDI plus other income) exceeds $25,000 if you file single, or $32,000 if you file married filing jointly. This means you could owe tax on a portion of your SSDI even if you have no other income, though this is uncommon.

The practical starting point is to add up all your income sources for the year. Then check whether that total meets the IRS filing requirement for your age and status. If it does, you file a return. If it doesn't, you generally don't have to — but some people file anyway to claim refundable tax credits like the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit, which can result in a refund even if you owe no tax.

Key Takeaways

  • SSDI payments are not taxed as regular income, but you must file a return if your other income (wages, interest, pensions) exceeds the IRS threshold for your age and filing status.
  • Part of your SSDI can be taxed if your combined income — SSDI plus half your SSDI plus other income — exceeds $25,000 (single) or $32,000 (married filing jointly).
  • You can use IRS Form SSA-1099 (the statement Social Security sends you) to determine your SSDI income for tax purposes.
  • Even if you don't have to file, you may want to file anyway if you have dependents or earned income, because refundable credits can give you money back.

How the IRS counts SSDI income differently than other income

The IRS treats SSDI income in a way that can seem confusing at first. SSDI itself is not counted dollar-for-dollar as taxable income. Instead, the IRS uses a formula called "combined income" to decide whether any of your SSDI gets taxed. Combined income is calculated as: your adjusted gross income (AGI) plus nontaxable interest plus half of your SSDI.

If your combined income stays below $25,000 (or $32,000 if married filing jointly), none of your SSDI is taxed. If it goes above that threshold, up to 50 percent of the excess can be taxed — and in some cases, up to 85 percent of your SSDI can be taxed if your combined income is very high. This is why someone with no wages or other income might still owe tax on SSDI, though it is rare.

For example: if you are single, receive $15,000 in SSDI, and have $12,000 in wages, your combined income is $12,000 + $0 (nontaxable interest) + $7,500 (half of $15,000 SSDI) = $19,500. Since $19,500 is below $25,000, none of your SSDI is taxed. You would only owe tax on the $12,000 in wages.

When you must file a return even with only SSDI income

If SSDI is your only income and you have no other earnings, interest, or pensions, you generally do not have to file a federal income tax return. The IRS filing requirement is based on your gross income from all sources, and SSDI alone usually does not meet that threshold.

However, you should file if you have any of the following: wages from work (even part-time), self-employment income, interest or dividend income, or if you are claimed as a dependent on someone else's return and have unearned income above a certain amount. You should also file if you want to claim the Earned Income Tax Credit (EITC), Additional Child Tax Credit, or American Opportunity Tax Credit — these are refundable credits that can give you money back even if you owe no tax.

The IRS publishes filing requirement tables each year based on age and filing status. For 2024, a single person under 65 with only SSDI income does not have to file. But if that same person has any wages, they must file if their total income exceeds $14,600. The thresholds are higher if you are 65 or older.

What documents you need to file taxes on SSDI

Social Security sends you Form SSA-1099 each January, which shows your SSDI income for the previous year. This is the document you use to report SSDI on your tax return. You will also receive other income documents if you have them: a W-2 from an employer, a 1099-INT for interest income, a 1099-NEC for self-employment or contract work, or a 1099-R for pension or retirement income.

Gather all these forms before you start your return. If you are missing a form by early March, contact the issuer directly — Social Security, your employer, your bank, or whoever paid you. Do not estimate or guess at amounts; use the actual figures from the forms.

If you file your own return using tax software or a paper form, you will enter the SSDI amount from your SSA-1099 on the appropriate line of Form 1040. If you work with a tax preparer or accountant, bring all your income documents and let them handle the calculation of whether any SSDI is taxable.

How to report SSDI on Form 1040

SSDI income goes on line 5b of Form 1040 (the main federal tax form). You report the full amount of SSDI you received during the year, as shown on your SSA-1099. The IRS then uses that figure, along with your other income, to calculate whether any of your SSDI is actually taxable under the combined income formula.

If you are using tax software, the program will walk you through entering your SSDI amount and will automatically calculate the taxable portion. If you are filing by hand or with a tax preparer, they will use IRS Worksheet 1 (for single filers) or Worksheet 2 (for married filers) to determine the taxable amount. You do not have to do this calculation yourself — the software or preparer does it.

The key point: you report the full SSDI amount on line 5b, not just the taxable portion. The IRS worksheet determines what portion, if any, is actually taxable income.

What happens if you work and receive SSDI

If you work and receive SSDI, you have two income sources to report: your wages (on a W-2 or 1099) and your SSDI (on your SSA-1099). Both go on your tax return. Your wages are taxed as normal income. Your SSDI is then evaluated under the combined income formula to see if any of it is taxable.

Working while on SSDI does not automatically disqualify you from benefits — Social Security has work incentive programs that allow you to earn money and keep some or all of your SSDI. However, if your earnings are high enough, Social Security may reduce or stop your SSDI payments under the Substantial Gainful Activity (SGA) rules. This is a separate issue from taxes, but it affects how much SSDI you actually receive during the year, which in turn affects what you report on your tax return.

For tax purposes, report what you actually received in SSDI during the year (shown on your SSA-1099), not what you were originally may have access to to. If Social Security reduced your payments mid-year because of work earnings, your SSA-1099 will reflect the reduced amount.

State taxes and SSDI

Most states do not tax SSDI income. However, a few states — including Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont — tax SSDI under certain conditions. The rules vary by state: some tax SSDI only if your total income exceeds a threshold, others tax it only if you are below a certain income level, and some have other specific rules.

If you live in one of these states, check your state tax agency's website or contact them directly to find out whether you owe state tax on your SSDI. You may need to file a state return even if you do not owe federal tax. Some states have their own worksheets to calculate the taxable portion of SSDI, similar to the federal formula but with different thresholds.

Frequently Asked Questions

Do I have to file taxes if I only receive SSDI and have no other income?

No, you generally do not have to file if SSDI is your only income. However, you should file if you want to claim refundable tax credits like the Earned Income Tax Credit or Child Tax Credit, because these can result in a refund even if you owe no tax.

Will I owe taxes on my SSDI if I have no other income?

Probably not. You would only owe tax on SSDI if your combined income (SSDI plus half your SSDI plus other income) exceeds $25,000 (single) or $32,000 (married filing jointly). With only SSDI and no other income, you would need very high SSDI payments to hit that threshold, which is uncommon.

What if I lost my job mid-year and started receiving SSDI?

Report both your wages (on your W-2) and your SSDI (on your SSA-1099) on your tax return. Your combined income determines whether any SSDI is taxable. You may owe tax on your wages, and possibly on a portion of your SSDI, depending on the total.

Can I deduct medical expenses related to my disability?

Yes, if your medical expenses exceed 7.5 percent of your adjusted gross income, you can deduct the excess on Schedule A (itemized deductions). This is separate from SSDI taxation and applies to anyone with high medical costs, not just SSDI recipients.

What if I disagree with the amount on my SSA-1099?

Contact Social Security directly to verify the amount. Your SSA-1099 should match your payment records. If there is an error, Social Security will issue a corrected form. Do not file your tax return until you have the correct SSA-1099.
