You must file taxes if your income exceeds the threshold, even if all of it comes from SSDI

Social Security Disability Insurance (SSDI) is not automatically tax-free. Whether you owe federal income tax depends on your total income for the year, not on whether that income comes from SSDI or wages. The IRS treats SSDI the same way it treats retirement benefits: you may owe tax on a portion of what you receive.

The threshold that triggers a filing requirement is low. For 2024, if you are single and your combined income (SSDI plus other income, calculated a specific way) exceeds $25,000, you must file. For married couples filing jointly, the threshold is $32,000. These thresholds have not changed since 1984, so they catch more people each year as SSDI payments rise.

Even if you do not owe tax, filing a return may benefit you. The Earned Income Tax Credit (EITC) and the Additional Child Tax Credit are refundable credits — they can result in a refund even if you owe no tax. If you have children or earned any wages alongside SSDI, filing could put money in your pocket.

Key Takeaways

  • SSDI is taxable income for federal tax purposes, and you must file if your combined income exceeds $25,000 (single) or $32,000 (married filing jointly).
  • The IRS uses a formula that includes half your SSDI plus all other income to determine whether any SSDI is taxable, not a straightforward dollar threshold.
  • Even if you owe no tax, filing may result in a refund if you have children or earned income, because the EITC and Child Tax Credit are refundable.
  • You receive a Form SSA-1099 from Social Security each January showing your SSDI for the prior year; use this to complete your tax return.
  • If you cannot afford to pay tax owed on SSDI, the IRS offers payment plans and hardship relief options.

How the IRS calculates whether your SSDI is taxable

The IRS does not tax all of your SSDI. Instead, it uses a two-tier formula to determine what portion, if any, is subject to tax. This formula is the reason the income thresholds exist and why two people receiving the same SSDI amount may owe different amounts of tax.

First, the IRS adds half your SSDI to all your other income (wages, interest, dividends, rental income, and other sources). If that sum is below $25,000 (single) or $32,000 (married filing jointly), none of your SSDI is taxable. If it exceeds that threshold but stays below $34,000 (single) or $44,000 (married), up to 50 percent of your SSDI becomes taxable. If it exceeds those higher thresholds, up to 85 percent of your SSDI becomes taxable.

Example: You receive $1,500 per month in SSDI ($18,000 per year) and earn $10,000 from part-time work. Half your SSDI is $9,000. Add that to your wages: $9,000 + $10,000 = $19,000. This is below $25,000, so none of your SSDI is taxable. You report only the $10,000 in wages on your return.

Another example: You receive $1,500 per month in SSDI ($18,000 per year) and have $8,000 in interest income. Half your SSDI is $9,000. Add that to the interest: $9,000 + $8,000 = $17,000. Still below $25,000, so none of your SSDI is taxable.

A third example: You receive $1,500 per month in SSDI ($18,000 per year) and earn $15,000 from work. Half your SSDI is $9,000. Add that to your wages: $9,000 + $15,000 = $24,000. Still below $25,000, so none of your SSDI is taxable. But if you earned $16,000 instead, the sum would be $25,000, and up to 50 percent of your SSDI ($9,000) would become taxable.

What documents you need and where to get them

Social Security mails you a Form SSA-1099 each January. This form shows your SSDI for the prior calendar year in Box 5. You need this form to complete your tax return. If you do not receive it by early February, contact Social Security at 1-800-772-1213 or visit your local Social Security office.

You will also need documentation of any other income you received: a W-2 from an employer, a 1099-INT from a bank (for interest), a 1099-DIV from an investment firm (for dividends), or other 1099 forms depending on your income sources. Gather these before you begin your return.

If you have a spouse and file jointly, you will each receive your own SSA-1099. Both forms are needed to calculate your combined income correctly.

When you might owe tax on SSDI even with low income

The most common scenario is when you have both SSDI and earned income from work. Even modest wages can push your combined income over the threshold. A person receiving $1,200 per month in SSDI ($14,400 per year) who earns $12,000 from part-time work will have a combined income of $21,000 (using the half-SSDI formula), which is still below the $25,000 threshold. But if they earn $13,000, the combined income becomes $20,700 — still safe. At $15,000 earned, the combined income reaches $22,200. At $22,000 earned, the combined income reaches $29,200, and now up to 50 percent of the SSDI becomes taxable.

Investment income also counts. If you receive $1,500 per month in SSDI and have $10,000 in savings that generates $500 in annual interest, that interest is added to the formula. Half your SSDI ($9,000) plus the interest ($500) equals $9,500, still below the threshold. But if you have $20,000 in savings generating $1,000 in interest, the combined income becomes $10,000, and you are still safe. However, if you receive a one-time distribution from a retirement account or sell an asset at a gain, that income counts in the year you receive it, and it can push you over the threshold.

Spousal income also matters if you file jointly. If you receive SSDI and your spouse works, their wages are added to the formula. A couple where one spouse receives $1,500 per month in SSDI and the other earns $30,000 per year will have a combined income of $39,000 (half the SSDI plus the wages), which exceeds the $32,000 threshold for married couples, and some SSDI becomes taxable.

Filing your return and reporting SSDI

You report SSDI on Form 1040 (the main federal income tax form) or Form 1040-SR if you are 65 or older. The SSA-1099 you receive shows your SSDI in Box 5. You enter this amount on line 5b of Form 1040 or Form 1040-SR, labeled "Social security benefits."

If you use tax software (such as IRS Free File, TurboTax, or H&R Block), the software will walk you through entering the SSA-1099 information and will automatically calculate whether any of your SSDI is taxable using the IRS formula. If you file by hand or with a tax preparer, they will perform the same calculation.

You do not need to do anything special to report SSDI. straightforward include the amount from Box 5 of your SSA-1099 on your return. The IRS will determine the taxable portion based on your total income.

What to do if you owe tax on SSDI

If your return shows that you owe tax on SSDI, you have several options. The simplest is to pay the full amount by the tax important date (usually April 15). You can pay online through IRS.gov, by mail, or by phone.

If you cannot pay in full, the IRS offers a short-term payment plan (paying within 180 days) and a long-term installment agreement (paying over months or years). You can set up a payment plan online at IRS.gov, by phone at 1-800-829-1040, or by mail. There is a setup fee, which varies depending on how you explore and how you pay.

You can also request Currently Not Collectible (CNC) status if you cannot pay at all right now. This temporarily pauses collection efforts, though interest and penalties continue to accrue. CNC status lasts up to 120 days and can be renewed.

If you believe you have a genuine hardship, you can request Offer in Compromise, which allows you to settle your tax debt for less than you owe. This is difficult to obtain and requires detailed financial documentation, but it is an option if your circumstances are severe.

Withholding tax from SSDI to avoid owing at tax time

You can ask Social Security to withhold federal income tax from your SSDI payments. This reduces the amount you receive each month but can prevent you from owing a large amount at tax time. You do this by completing Form W-4V (Voluntary Withholding Request) and submitting it to Social Security.

You can choose to have 7 percent, 10 percent, 12 percent, or 22 percent of your SSDI withheld. Social Security will send the withheld amount to the IRS on your behalf. When you file your return, the IRS will credit the withholding against any tax you owe, and you may receive a refund if you withheld more than you owed.

This is optional and is most useful if you know you will owe tax and want to spread the payment across the year rather than paying a lump sum at tax time. You can change or stop withholding at any time by submitting a new Form W-4V.

Frequently Asked Questions

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

Only if your combined income (half your SSDI plus any other income) exceeds $25,000 (single) or $32,000 (married filing jointly). If you receive only SSDI and nothing else, you would need SSDI of $50,000 or more per year to reach the threshold, which is rare. However, filing may still benefit you if you have children, because the Child Tax Credit or EITC could result in a refund.

What if I earned wages and received SSDI in the same year?

Both count toward your income threshold. Add half your SSDI to your total wages (and any other income). If the sum exceeds $25,000 (single) or $32,000 (married), you must file. Your employer will send you a W-2; Social Security will send you an SSA-1099. Report both on your return.

Can I deduct my medical expenses or disability-related costs from my SSDI?

No. SSDI is not earned income, so you cannot reduce it by claiming business expenses or work-related costs. You can only deduct medical expenses if you itemize deductions on Schedule A, and only the amount exceeding 7.5 percent of your adjusted gross income. For most SSDI recipients, the standard deduction is larger, so itemizing does not help.

What if Social Security sends me an incorrect SSA-1099?

Contact Social Security when ready at 1-800-772-1213 or visit your local office. Ask them to issue a corrected SSA-1099. If you have already filed your return with the incorrect amount, you can file an amended return (Form 1040-X) once you receive the corrected form. Do not delay; the sooner you correct it, the sooner any refund will be processed.

Do I need to report SSDI on state income tax returns?

This depends on your state. Most states do not tax SSDI, but a few do. Check your state's tax authority website or ask a tax preparer. If your state does tax SSDI, you will report it on your state return using the same SSA-1099 form.
