You may get a tax refund on SSDI, but only if you had taxes withheld from other income or you owe less tax than you paid

Social Security Disability Insurance (SSDI) itself is not taxable income for most people — you do not pay federal income tax on your SSDI benefit. But if you have other income (wages, interest, rental income, or self-employment earnings), you may owe tax on that income. If you paid too much tax during the year through withholding or estimated tax payments, you get a refund when you file. The refund comes from overpaying on your non-SSDI income, not from the SSDI itself.

The key question is not whether SSDI is taxable, but whether you had enough other income to owe tax in the first place, and whether you paid the right amount. Many people on SSDI have little or no other income and therefore owe no tax and get no refund. Others work part-time or have investment income, and may owe tax on that — and may have overpaid it.

Key Takeaways

  • SSDI benefits themselves are not taxable income for most people, so you do not owe federal tax on the benefit amount.
  • A tax refund comes from overpaying tax on other income you earned (wages, self-employment, interest), not from SSDI.
  • If you have no income besides SSDI, you will not owe tax and will not get a refund.
  • If you work while on SSDI and have taxes withheld from your paycheck, you may get a refund if you withheld more than you owed.
  • You must file a tax return to claim a refund, even if you are not required to file.

When SSDI is taxable and when it is not

SSDI is taxable only if your combined income exceeds a certain threshold. Combined income means your adjusted gross income plus nontaxable interest plus half of your SSDI benefit. For 2024, if you are single and your combined income is under $25,000, your SSDI is not taxable. If you are married filing jointly, the threshold is $32,000. These thresholds have not changed since 1984.

Most people on SSDI fall below these thresholds because SSDI is the only income they have. If you have wages from work, investment income, or self-employment income, you add those to the calculation. If your combined income is above the threshold, up to 50 percent or 85 percent of your SSDI benefit becomes taxable, depending on how far above the threshold you are.

The IRS publishes a worksheet each year to calculate whether your SSDI is taxable. You can find it in the instructions to Form 1040 (the main federal income tax form) under "Are Your Benefits Taxable?" The Social Security Administration also sends you a Form SSA-1099-SM in January showing how much SSDI you received in the prior year, which you use to complete the worksheet.

How work income affects your tax refund while on SSDI

If you work while receiving SSDI, your employer withholds federal income tax from your paycheck. That withholding is what creates a refund if you withheld more than you owed. The amount you owe depends on your total income for the year — wages plus any taxable SSDI plus any other income.

Many people on SSDI who work part-time have little total income and therefore owe little or no tax. If your employer withheld tax from your paycheck but you owed no tax (because your income was below the standard deduction), you get a refund of the full amount withheld. The standard deduction for 2024 is $14,600 for a single person and $29,200 for married filing jointly.

You can adjust your withholding by filing a new Form W-4 with your employer. If you know you will not owe tax, you can claim exemptions on the W-4 so less is withheld, and you keep more of your paycheck instead of waiting for a refund. The IRS has a withholding calculator on its website to help you figure out the right amount.

Self-employment income and estimated tax payments

If you are self-employed while on SSDI, you do not have an employer to withhold tax. Instead, you are supposed to make quarterly estimated tax payments to the IRS. If you underpay your estimated taxes, you may owe money when you file. If you overpay, you get a refund.

Self-employment income also affects your SSDI benefit itself through the Substantial Gainful Activity (SGA) threshold. In 2024, if your net self-employment income exceeds $1,550 per month, Social Security may find that you are working at a substantial level and may suspend your SSDI. This is separate from the tax question, but it is important to track if you are self-employed.

When you file your tax return, you report self-employment income on Schedule C (Profit or Loss from Business) and pay self-employment tax on Schedule SE. You also report any estimated tax payments you made during the year. If you paid more in estimated tax than you owed, you get a refund.

Investment income and other sources

Interest, dividends, capital gains, and rental income all count toward your combined income for the purpose of determining whether your SSDI is taxable. They also affect your total tax liability. If you have investment income, you may owe tax on it even if you have no wages.

Banks and investment firms send you Forms 1099 (1099-INT for interest, 1099-DIV for dividends, 1099-B for sales of securities) in January. You report these on your tax return. If you had tax withheld on any of this income, that withholding counts toward your total tax paid and may result in a refund.

Some people on SSDI have very small amounts of interest or dividend income from savings or inherited accounts. These amounts usually do not push you over the SSDI taxability threshold, but they do count in the combined income calculation, so it is worth tracking them.

Filing a return to claim your refund

You must file a federal income tax return to get a refund, even if you are not required to file. You are required to file if your income exceeds the standard deduction for your filing status. But even if your income is below the standard deduction, if you had taxes withheld, you should file to claim that refund.

You can file on paper using Form 1040 and any schedules you need (Schedule C if self-employed, Schedule SE for self-employment tax, Schedule D if you sold investments). You can also file electronically using tax software or a tax preparer. The IRS offers free filing software through its Free File program if your income is below a certain threshold (usually around $79,000).

You can file as early as January after the year ends. The important date to file and claim a refund is April 15 of the following year, but if you file after that date, you can still claim a refund for up to three years back. If you are owed a refund, there is no penalty for filing late — the IRS will not pursue you for a refund you are owed.

How long it takes to get your refund

If you file electronically and choose direct deposit to your bank account, the IRS typically issues your refund within 21 days. If you file on paper, it takes longer — usually 4 to 6 weeks. You can check the status of your refund on the IRS website using the "Where's My Refund?" tool, which updates every 24 hours.

If you file early in the tax season (January or February), you may get your refund faster because the IRS is processing fewer returns. If you file closer to the April 15 important date, it may take longer. The IRS also holds some returns for additional review, which can delay a refund by several weeks.

Frequently Asked Questions

Do I have to file a tax return if I only get SSDI and no other income?

No. If SSDI is your only income and it is below the taxability threshold (which it will be if it is your only income), you do not owe tax and are not required to file. However, if you had any taxes withheld from other income during the year, you should file to claim your refund.

Will getting a tax refund affect my SSDI benefit?

No. A tax refund is not counted as income for SSDI purposes. It does not affect your benefit amount or your may be able to access. The IRS and Social Security are separate agencies and do not share refund information in a way that changes your benefit.

What if I owe taxes instead of getting a refund?

If your total tax owed is more than what was withheld or paid in estimated taxes, you owe the difference when you file. You can pay by credit card, debit card, bank transfer, or check. If you cannot pay in full, the IRS offers payment plans. Owing taxes does not affect your SSDI benefit.

Can I claim the Earned Income Tax Credit while on SSDI?

Yes, if you have earned income (wages or self-employment income) and your total income is below the limit for your filing status. The Earned Income Tax Credit is a refundable credit, meaning you can get a refund even if you owe no tax. In 2024, the income limit is around $63,398 for married filing jointly. You claim it on Schedule EIC or Form 1040.

What documents do I need to file my tax return?

You need your Social Security number, your Form SSA-1099-SM (showing your SSDI), any Forms W-2 from employers, any Forms 1099 from banks or investment firms, and records of any estimated tax payments you made. Keep receipts for any business expenses if you are self-employed. The IRS does not require you to attach these documents, but keep them for your records in case of an audit.
