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

Social Security Disability Insurance (SSDI) benefits themselves are not taxable income. However, if you have other income — from work, a pension, interest, or rental property — you may be required to file a federal tax return. The IRS does not care that you receive disability benefits; it cares about your total income from all sources. Whether you must file depends on how much non-SSDI income you earned and your filing status.

The threshold that triggers a filing requirement changes each year. For 2024, a single person with no dependents must file if their gross income exceeds $14,600. If you are married filing jointly and both spouses have income, the threshold is higher. These numbers shift annually, so you need to check the current year's requirement before deciding whether to file.

Many people on SSDI do file taxes anyway, even when not required, because they had taxes withheld from other income sources (like a part-time job) and want a refund. If you fall into this situation, filing is how you recover that money.

Key Takeaways

  • SSDI payments themselves are never taxable, but other income you earn counts toward the IRS filing threshold.
  • You must file a federal tax return if your total income from non-SSDI sources exceeds the annual threshold, which varies by filing status and changes each year.
  • If your employer withheld taxes from wages or other income, you should file to recover that money as a refund, even if filing is not required.
  • You report SSDI income on your tax return in a specific way: it appears on line 5b of Form 1040, but the amount is usually zero because benefits are not taxable.

How the IRS counts income when you receive SSDI

The IRS has a specific definition of "gross income" for filing purposes. SSDI benefits do not count. Wages from work do count, even if you earned them through a work incentive program like Impairment Related Work Expenses (IRWE) or Plan to Achieve Self-Support (PASS). Interest from a savings account counts. Distributions from a retirement account count. Rental income counts. Taxable scholarships count.

If you are married and file jointly, the IRS adds your spouse's income to yours when determining whether you cross the filing threshold. If you are married filing separately, each person's income is evaluated independently, but filing separately often results in a higher tax bill and is rarely advantageous.

Some income is excluded from the gross income calculation. For example, Supplemental Security Income (SSI) is not counted, though SSI and SSDI are different programs. Certain veterans' benefits and workers' compensation payments may also be excluded, depending on the type. If you receive multiple forms of information, you need to know which counts and which does not.

The annual income thresholds and how they change

The IRS updates filing thresholds each January based on inflation. The threshold for a single filer with no dependents has been rising steadily. In 2023 it was $13,850; in 2024 it rose to $14,600. In 2025, it will likely be higher again. You can find the current year's threshold on the IRS website or by calling the IRS at 1-800-829-1040.

Your filing status matters. A married couple filing jointly has a much higher threshold than a single person — roughly double. A head of household (usually a single parent) has a threshold between the two. If you are over 65, your threshold is higher by about $1,850, regardless of filing status. These adjustments exist because older filers and families have different tax situations.

The threshold applies to your gross income, not your net income. If you are self-employed, you count your gross receipts minus certain business expenses, but the calculation is more complex than for wage earners. If you are unsure whether your income crosses the line, it is safer to file; the IRS will not penalize you for filing when not required.

What happens if you do not file when you should

If you are required to file and do not, the IRS can assess a failure-to-file penalty. The penalty is usually 5 percent of the unpaid tax for each month the return is late, up to 25 percent total. If you owe no tax (because your withholding covered your liability), the penalty is smaller or zero, but you still face the administrative burden of the IRS contacting you.

More importantly, if you had taxes withheld from wages or other income and did not file, you will not receive your refund. The IRS will not send you money you are owed unless you file a return claiming it. You have three years to file and claim a refund; after that, the money goes to the U.S. Treasury.

If you receive SSDI and work, your earnings may also affect your SSDI payment amount through a process called the Substantial Gainful Activity (SGA) test. This is separate from tax filing, but it is another reason to track your income carefully. Failing to report work income to Social Security can result in an overpayment that you must repay.

How to report SSDI on your tax return

When you file Form 1040 (the main federal tax form), SSDI appears on line 5b, labeled "Social Security benefits." You enter the amount of SSDI you received during the year. However, because SSDI is not taxable, you will also enter that same amount on line 5c, which is the "taxable amount" of Social Security. In most cases, this results in zero taxable Social Security income.

There is an exception: if you have substantial other income, a portion of your SSDI may become taxable. This happens only if your "combined income" (adjusted gross income plus nontaxable interest plus half of your Social Security benefits) exceeds a threshold set by the IRS. For 2024, that threshold is $25,000 for a single filer and $32,000 for married filing jointly. Very few SSDI recipients reach this threshold, but it is possible if you have significant wages, pensions, or investment income.

If you use tax software or work with a tax preparer, tell them you receive SSDI. They will know how to enter it correctly. If you file by hand, the Form 1040 instructions include a worksheet to calculate whether any of your benefits are taxable.

Work incentives and how they affect your tax filing

Social Security offers work incentives that allow you to earn money without losing your SSDI benefits when ready. Two common ones are IRWE and PASS. These programs reduce the income Social Security counts when deciding whether you have exceeded the SGA threshold, but they do not reduce the income the IRS counts for tax purposes.

For example, if you use IRWE to deduct the cost of a service animal or attendant care from your work income, Social Security will not count that expense when calculating your SGA. However, the IRS will still count your full wages as gross income for tax filing purposes. You may owe taxes on income that Social Security does not count toward your benefit.

This distinction confuses many people on SSDI who work. The two agencies use different rules. Social Security cares about whether you can work; the IRS cares about how much you earned. Both matter, and you need to understand each separately.

When to file even if you are not required to

You should file a tax return even if your income is below the filing threshold if any of the following is true: taxes were withheld from your wages, you are self-employed and earned $400 or more, you received an Earned Income Tax Credit (EITC) or Child Tax Credit that you want to claim, or you had a tax-deductible loss you want to carry forward.

The EITC is a refundable credit, meaning the IRS will send you money even if you owe no tax. If you worked part-time while on SSDI and earned less than the filing threshold, you may still may have access to for the EITC. Filing is the only way to receive it. Similarly, if you have dependent children, the Child Tax Credit can result in a substantial refund.

Many people on SSDI who work part-time end up in this situation: they earn too little to be required to file, but filing results in a refund because of credits or withholding. It takes 15 to 30 minutes to file online using free software, and the refund can be $500 to $3,000 or more. It is worth doing.

Free tax filing resources for people on SSDI

The IRS offers free tax filing software through the Free File program if your income is below a certain threshold (usually around $79,000). You can access it through IRS.gov. Many of these programs are designed to be straightforward and walk you through the process step by step. If you have SSDI income and some wages, most free software will handle it correctly.

If you prefer to file by mail, you can read Form 1040 and the instructions from IRS.gov, fill them out by hand, and mail them to the address listed in the instructions. This takes longer and is more error-prone, but it is free.

If your tax situation is complex — for example, you are self-employed, have rental income, or are unsure whether any of your SSDI is taxable — you may want to work with a tax professional. Some nonprofits offer free tax preparation for low-income filers. You can find one near you through the IRS Volunteer Income Tax information (VITA) program by calling 211 or visiting the IRS website.

Frequently Asked Questions

Do I have to report my SSDI to the IRS even if I do not file a tax return?

No. If you are not required to file a tax return, you do not report your SSDI to the IRS. SSDI is not taxable income, and the IRS does not require you to report income that is not taxable. However, if you do file for other reasons (to claim a refund, for example), you will report your SSDI on line 5b of Form 1040.

If I work and receive SSDI, do I file taxes on my wages?

Yes, if your total income (wages plus any other income) exceeds the filing threshold for your status. Your SSDI does not count toward the threshold, but your wages do. If you earned $15,000 in wages and received $12,000 in SSDI, you must file because your wages alone exceed the threshold. The SSDI amount does not change this requirement.

What if I earned money but had no taxes withheld?

You still may be required to file if your income exceeds the threshold. If you earned $16,000 and had no taxes withheld, you owe taxes and must file to pay them. Filing late results in penalties and interest. If you are self-employed, you also owe self-employment tax, which is separate from income tax.

Can I file my taxes online if I receive SSDI?

Yes. Free IRS software and commercial tax software both handle SSDI correctly. You enter your SSDI amount on line 5b, and the software calculates whether any of it is taxable (usually it is not). Filing online is faster and more accurate than filing by mail.

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

You report only the SSDI you actually received during the year. If you started receiving SSDI in June, you report only the six months of benefits you received. The same applies if you stopped receiving SSDI partway through the year. Social Security sends you a Form SSA-1099 each January showing the total you received in the previous year; use that number on your tax return.
