You must file a tax return if your income exceeds the IRS threshold for your filing status, even if all your income is SSDI

SSDI payments themselves are not taxable income. However, you must file a federal tax return if you have other income—wages, self-employment earnings, interest, dividends, or certain other sources—that pushes your total above the IRS filing threshold. The threshold depends on your age, filing status, and whether you are claimed as a dependent.

The IRS does not care that your SSDI is tax-free. It cares about your total income from all sources. If you worked part-time, received a pension, had investment income, or earned money from a side business, you may owe a return even if SSDI is your largest income source.

Additionally, even if you fall below the filing threshold, filing a return can be worth doing if you paid taxes through withholding or if you are may have access to to refundable tax credits like the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit. The IRS will not send you money you are owed unless you file.

Key Takeaways

  • SSDI is not taxable, but other income you receive is, and you must file a return if your non-SSDI income exceeds the IRS threshold for your filing status.
  • The filing threshold varies by age and filing status; for 2024, a single person under 65 must file if their income exceeds $14,600, but thresholds are higher for those 65 and older.
  • Even if you do not owe taxes, filing a return is often worth doing if you paid taxes through withholding or if you may be may have access to to refundable credits like the EITC.
  • You can use IRS Form 1040-SR (for those 65 and older) or Form 1040, and you should report SSDI on your return even though it is not taxable, because the IRS uses that information to calculate whether other income is taxable.
  • If you work and receive SSDI, you must also track your earnings against the Social Security work incentive rules, which are separate from tax filing requirements.

How the IRS filing threshold works when you receive SSDI

The IRS sets a minimum income level below which you do not have to file. This threshold is not the same for everyone. It depends on three things: your age, your filing status (single, married filing jointly, head of household), and whether someone else claims you as a dependent.

For 2024, a single person under age 65 must file if their gross income is $14,600 or more. A single person age 65 or older must file if their gross income is $18,350 or more. If you are married filing jointly and both spouses are under 65, you must file if your combined income is $29,200 or more. These thresholds increase slightly each year for inflation.

The key word is gross income. SSDI does not count toward this threshold. Only your other income—wages, self-employment, interest, dividends, rental income, pensions, annuities, and certain other sources—counts. If you earned $12,000 in wages and received $20,000 in SSDI, your gross income for filing purposes is $12,000, and you would not be required to file (assuming you are under 65 and single).

However, if you are claimed as a dependent by someone else—for example, your adult child claims you on their return—the threshold is much lower. A dependent under 65 must file if their gross income exceeds $1,250 (for 2024). This rule catches many people by surprise and is a common reason SSDI recipients end up owing taxes they did not expect.

When filing a return makes sense even if you do not have to

The IRS filing threshold is a floor, not a ceiling. You can file even if you fall below it, and you often should. The main reason is refundable tax credits—money the IRS will send you if you file, even if you owe no tax.

The Earned Income Tax Credit (EITC) is the most common. If you worked and earned less than roughly $60,000 (depending on filing status and number of children), you may be may have access to to a credit worth hundreds or even thousands of dollars. SSDI does not count as earned income for EITC purposes, but wages do. If you worked part-time while receiving SSDI, you may may have access to for the EITC, and you must file to claim it.

The Additional Child Tax Credit is another refundable credit. If you have children and your income is low, you may be may have access to to a credit that exceeds the tax you owe, resulting in a refund. Again, you must file to receive it.

You should also file if you had taxes withheld from any income during the year. If your employer withheld federal income tax from your wages, or if you made estimated tax payments, filing a return is how you claim that money back if you end up owing no tax or owing less than what was withheld.

How to report SSDI on your tax return

SSDI appears on your tax return even though it is not taxable. You report it on Form 1040 (or Form 1040-SR if you are 65 or older) on the line labeled "Social Security benefits." The IRS uses this number to determine whether any of your benefits are taxable—a calculation that applies to people with very high incomes, not most SSDI recipients.

You will receive a Form SSA-1099 from Social Security each January showing the total SSDI you received the previous year. Use this form to fill in the amount on your tax return. If you did not receive an SSA-1099 but received SSDI, contact Social Security to request one.

Do not leave the SSDI line blank, even though the amount is not taxable. The IRS cross-checks your return against Social Security's records, and discrepancies can trigger an audit or delay your refund. If you received SSDI for only part of the year, report only the amount you actually received, not an annualized figure.

The relationship between tax filing and SSDI work incentives

Filing a tax return and tracking your earnings for SSDI work incentive purposes are two separate things, but they overlap. If you work while receiving SSDI, you must report your earnings to Social Security, and you must also report them on your tax return if they exceed the filing threshold.

Social Security has its own rules about how much you can earn before your SSDI payment is reduced. For 2024, if you are under full retirement age, Social Security reduces your benefit by $1 for every $2 you earn above $23,400 per year. These are not tax rules; they are SSDI program rules. You can owe taxes on earnings without losing SSDI, and you can lose SSDI due to earnings without owing taxes.

The IRS does not care about Social Security's earnings limits. If you earned $30,000 in wages and received $20,000 in SSDI, you owe taxes on the $30,000 (assuming you are single and under 65). Social Security may reduce your SSDI payment because of the earnings, but that does not change your tax obligation.

Keep records of all your earnings—wages, self-employment income, tips, and any other money you made—because you will need them both for your tax return and to report to Social Security. Many SSDI recipients use Social Security's work incentive programs, like Impairment Related Work Expenses (IRWE) or Plans to Achieve Self-Support (PASS), to reduce their countable earnings. These programs do not reduce your tax liability, but they can protect your SSDI payment.

Special situations: Married couples, dependents, and non-citizens

If you are married and file jointly, both spouses' income counts toward the filing threshold, but SSDI received by either spouse does not. If one spouse receives SSDI and the other receives wages, you add only the wages to determine whether you must file.

If you are married but file separately, the rules are stricter. If you file separately and your spouse itemizes deductions, you must also itemize (you cannot take the standard deduction). This can result in owing more tax. Most married couples are better off filing jointly, but a tax professional can advise you on your specific situation.

If you are a non-citizen, you may still receive SSDI, and you must still file a tax return if your income exceeds the threshold. Non-citizens with a Social Security number or Individual Taxpayer Identification Number (ITIN) file the same forms as citizens. If you are not sure whether you need an ITIN, contact the IRS or a tax professional.

How to file: Forms and where to get help

You can file your tax return on paper or electronically. The IRS provides free filing software through its Free File program if your income is below a certain threshold (roughly $79,000 for 2024). You can also use a tax professional or a community organization that offers free tax preparation.

If you are 65 or older, use Form 1040-SR, which is simpler than the regular Form 1040. If you are younger, use Form 1040. Both forms ask for your SSDI amount and your other income. If you have only SSDI and no other income, you do not need to file, and you do not need to do anything.

Many disability organizations and senior centers offer free tax preparation during tax season (January through April). The IRS also maintains a directory of free tax clinics. If you have questions about whether you must file or how to report your SSDI, these resources can help without charging you.

Frequently Asked Questions

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

No. SSDI is not taxable income, so if SSDI is your only income source, you do not have to file a federal tax return. However, if you also received wages, self-employment income, interest, or other income, you may need to file depending on the total amount.

What if I worked part-time and received SSDI—do I have to file?

It depends on how much you earned. If your wages alone exceed the filing threshold for your age and status (for example, $14,600 for a single person under 65 in 2024), you must file. Even if you fall below the threshold, filing is often worth doing if you paid taxes through withholding or if you may have access to for the EITC.

Will filing a tax return affect my SSDI payment?

Filing a tax return itself does not affect your SSDI payment. However, if you earned income that triggered the filing requirement, Social Security may reduce your SSDI based on your earnings under its own work incentive rules. These are separate from tax rules. Report your earnings to Social Security regardless of whether you file a tax return.

What if someone claims me as a dependent—do I still have to file?

If you are claimed as a dependent, the filing threshold is much lower: $1,250 in gross income for 2024 (not counting SSDI). If you have any income above this amount—even $100 in interest—you must file. Check with the person claiming you to confirm they are doing so, because this affects your filing requirement.

Where do I get my Form SSA-1099 to report my SSDI on my tax return?

Social Security mails Form SSA-1099 to you each January showing your prior-year SSDI. If you do not receive one or lose it, you can create a my Social Security account online at ssa.gov, log in, and read a copy. You can also call Social Security at 1-800-772-1213 to request one.
