Most SSDI recipients pay no federal income tax on their benefits

If SSDI is your only income source, you will not owe federal income tax on those benefits. The Social Security Administration does not withhold taxes from SSDI payments, and most people who receive only SSDI have income too low to trigger a tax filing requirement.

The rule changes if you have other income—wages, self-employment earnings, interest, or retirement account withdrawals. Then a portion of your SSDI may become taxable. The threshold is low: for a single filer in 2024, you can have as little as $25,000 in "combined income" before SSDI taxation begins. Combined income includes your SSDI plus half of your SSDI plus all other income sources.

State and local taxes are separate. Some states do not tax SSDI at all. Others tax it the same way the federal government does. A few tax SSDI only if you also receive a pension. You need to check your specific state's rules.

Key Takeaways

  • SSDI alone is not taxable at the federal level, and the SSA does not withhold taxes from your monthly payment.
  • If you have other income, part of your SSDI may become taxable once your combined income exceeds $25,000 (single filer) or $32,000 (married filing jointly).
  • State tax treatment of SSDI varies: some states exempt it entirely, others tax it like the federal government does, and a few have their own rules.
  • You may still need to file a federal tax return even if you owe no tax, because you could be due a refund from taxes withheld on other income.

How combined income determines whether SSDI is taxable

The SSA uses a formula called "combined income" to decide if any of your SSDI becomes taxable. Combined income is calculated as: your adjusted gross income (AGI) plus nontaxable interest plus half of your SSDI.

If your combined income stays below the "base amount," no SSDI is taxable. The base amount is $25,000 for a single filer, $32,000 for married filing jointly, and $0 for married filing separately. Once combined income exceeds the base amount, up to 50 percent of the excess can become taxable. If combined income exceeds a second threshold ($34,500 for single filers, $44,000 for married filing jointly), up to 85 percent of the excess can become taxable.

Example: You are single and receive $1,200 per month in SSDI ($14,400 per year). You also earn $15,000 from part-time work. Your combined income is $15,000 plus $7,200 (half your SSDI) = $22,200. This is below $25,000, so no SSDI is taxable. If you earned $20,000 instead, combined income would be $27,200. The excess over $25,000 is $2,200. Up to 50 percent of that ($1,100) becomes taxable.

What counts as income for the combined income calculation

The SSA counts most money you receive as income for this calculation. Wages and self-employment income are included. Interest and dividends are included. Distributions from retirement accounts (401(k), IRA, pension) are included at their full amount, not just the taxable portion.

Some income does not count. Supplemental Security Income (SSI) is excluded. Workers' compensation is excluded. Certain veterans' benefits are excluded. Gifts and inheritances are excluded. Refunds of taxes you paid are excluded. Railroad Retirement benefits are excluded.

Nontaxable interest—such as interest from municipal bonds—is added back into the calculation even though it is not taxable income. This means you can be pushed into SSDI taxation even if your actual tax-filing income is low.

State tax treatment of SSDI varies widely

Thirteen states do not tax SSDI at all: Illinois, Iowa, Kansas, Louisiana, Massachusetts, Michigan, Mississippi, Missouri, New York, North Carolina, Ohio, Pennsylvania, and Virginia. If you live in one of these states, you will not owe state income tax on SSDI regardless of your other income.

Most other states follow the federal rule: they tax SSDI the same way the IRS does, using the combined income formula. A handful of states have their own rules. Colorado, Connecticut, and Minnesota tax SSDI only if you also receive a pension or other retirement income. Georgia taxes SSDI only if your income exceeds a certain threshold. You can confirm your state's rule by contacting your state's department of revenue or checking their website.

If you moved to a new state during the year, you may owe tax to both states. Some states offer credits for taxes paid to other states, but not all do. If you split the year between two states, file returns in both and check whether either offers a credit.

When you must file a federal tax return despite owing no tax

You may have no tax owed on your SSDI but still need to file a federal return. This happens when taxes were withheld from other income—wages, retirement distributions, or unemployment benefits—and you are may have access to to a refund.

If you worked and had taxes withheld from your paycheck, you should file to claim that refund. If you withdrew money from a traditional IRA or 401(k) and taxes were withheld, file to get back any overpayment. If you received unemployment benefits and had taxes withheld, file to recover that money.

The IRS does not automatically refund you. You must file Form 1040 or 1040-SR (for people 65 and older) to claim the refund. You can file by mail or electronically using free software through the IRS Free File program if your income is below the threshold (which it likely is if SSDI is your main income source).

How to report SSDI on your tax return

If any portion of your SSDI is taxable, you will receive a Social Security Benefit Statement (Form SSA-1099) by January 31 of the following year. This form shows the total SSDI you received and is used to calculate the taxable portion.

You report SSDI on line 5b of Form 1040 or 1040-SR. You do not report it on a W-2 or 1099 form—the SSA issues its own statement. If you use tax software, it will walk you through entering the information from your SSA-1099. If you file by mail, include the form with your return.

If you received SSDI for only part of the year—for example, you started receiving it in June—the SSA-1099 will show only the benefits paid from June onward. The same combined income calculation applies; you just use the actual SSDI amount you received.

What happens if you underreport or fail to report SSDI income

SSDI is reported to the IRS automatically by the SSA. If you file a return that does not include SSDI income that should be there, the IRS will notice the discrepancy and contact you. You will be asked to file an amended return and may owe back taxes, interest, and penalties.

If the underreporting is large or appears intentional, the IRS can assess a penalty of 20 percent of the underpaid tax. Interest accrues from the original due date. If you straightforward made a mistake, contact the IRS when ready and file an amended return (Form 1040-X). The IRS is more lenient with taxpayers who correct errors themselves than with those caught during an audit.

The safest approach is to report all SSDI you received, even if you believe none of it is taxable. If you are unsure whether any portion is taxable, use the combined income formula or contact a tax professional. The cost of a consultation is far less than the cost of penalties and interest.

Frequently Asked Questions

Do I have to file a tax return if I only receive SSDI and nothing else?

No. If SSDI is your only income source, you have no tax filing requirement at the federal level. The SSA does not withhold taxes, and you will owe nothing. However, check your state's rules—some states have their own filing requirements even when federal law does not.

What if I work part-time and receive SSDI—do I still have to file?

Yes. You must file a federal return because you have wages subject to withholding. You will report both your wages and your SSDI. Depending on the amounts, some of your SSDI may be taxable. Filing allows you to claim any refund due from taxes withheld on your wages.

Can I reduce the amount of SSDI that becomes taxable by earning less?

Yes, but only if you are close to the threshold. If your combined income is just above $25,000, reducing other income can push you below the threshold and make all SSDI nontaxable. However, if you are well above the threshold, the tax benefit of earning less may not be worth the loss of income. Consult a tax professional or financial advisor to model your specific situation.

If I live in a state that does not tax SSDI, do I still owe federal tax on it?

State and federal taxes are separate. Living in a state that exempts SSDI does not change your federal tax obligation. If your combined income exceeds the federal threshold, part of your SSDI is taxable at the federal level regardless of your state's rule. You will owe federal tax but not state tax.

What if I received SSDI but then went back to work and my benefits stopped?

Report only the SSDI you actually received during the year. The SSA-1099 will show the exact amount. If benefits stopped partway through the year, that is the amount you report. Your combined income calculation uses only the SSDI you received, not the amount you would have received if benefits had continued.
