Whether you must file taxes on SSDI depends on your total income
You may owe federal income taxes on your Social Security Disability Insurance (SSDI) benefits, but only if your combined income exceeds a certain threshold. The IRS counts SSDI as income for tax purposes, but it is not automatically withheld the way wages are. This means you could owe taxes even if no money was taken from your checks.
The threshold that triggers a tax filing requirement depends on your filing status and whether you have other income sources — such as wages, pensions, or investment earnings. If you are under the threshold, you will not owe federal income tax on your SSDI, even if you file. If you are over it, some of your benefits become taxable.
The exact amount of SSDI that becomes taxable is calculated using a formula the IRS calls "combined income." This is not the same as your total SSDI payment. Understanding where you stand requires knowing both your SSDI amount and what other income you receive.
Key Takeaways
- You must file federal taxes if your combined income (SSDI plus other income) exceeds the threshold for your filing status, which ranges from $25,000 to $34,000 for most people.
- Combined income includes your SSDI benefits, wages, pensions, interest, dividends, and other earnings, calculated using a specific IRS formula.
- If you file and your income is below the threshold, you will not owe tax on your SSDI, but filing may still benefit you if you paid taxes withheld from other income.
- Some states tax SSDI benefits even when the federal government does not, so you may need to file a state return separately.
- The Social Security Administration sends Form SSA-1099 each January showing your annual SSDI amount, which you need to complete your federal tax return.
How the IRS calculates whether your SSDI is taxable
The IRS uses a two-step calculation to determine if any of your SSDI becomes taxable income. The first step is finding your combined income, which is your adjusted gross income plus nontaxable interest plus half of your SSDI benefits. This formula means that even if you have no other income, half your SSDI counts toward this calculation.
The second step compares your combined income to a base amount set by the IRS. For 2024, the base amounts are $25,000 if you file as single, $32,000 if you file as married filing jointly, and $0 if you file as married filing separately. If your combined income exceeds the base amount, up to 85 percent of the excess becomes taxable, though no more than 85 percent of your total SSDI can be taxed in any year.
This means a person filing as single with $30,000 in combined income would have $5,000 of income above the $25,000 base. Up to 85 percent of that $5,000 — or $4,250 — could become taxable SSDI. The actual taxable amount depends on your specific situation and may be lower.
What counts as income for this calculation
Combined income includes more than just wages. The IRS counts wages from employment, net earnings from self-employment, pensions, annuities, capital gains, dividends, interest (including tax-exempt interest), rental income, and royalties. If you receive workers' compensation, some of it may count depending on how it is structured.
SSDI itself is included in the calculation — specifically, half of your annual SSDI benefit amount is added to your other income to determine combined income. This is why someone with no other income source can still have a combined income figure that matters for tax purposes.
Money that does not count includes Supplemental Security Income (SSI), which is a separate program; certain veterans' benefits; and some other specific payments. If you receive both SSDI and SSI, only the SSDI counts toward this calculation.
Filing thresholds for different situations
The IRS sets different income thresholds depending on your age and filing status. For 2024, you must file a federal return if your gross income meets or exceeds the standard deduction for your situation. For SSDI recipients specifically, the threshold at which some benefits become taxable is lower than the general filing requirement.
If you are single and under 65, you must file if your gross income is $14,600 or more. However, you may owe taxes on SSDI if your combined income exceeds $25,000, which is a different calculation. If you are 65 or older, the gross income threshold is higher, but the SSDI taxability threshold remains the same.
If you are married filing jointly and both spouses are under 65, you must file if your combined gross income is $29,200 or more. The SSDI taxability threshold for married filing jointly is $32,000 in combined income. These numbers change each year, so check the current IRS guidelines or Form 1040 instructions for the year you are filing.
When you should file even if you do not owe tax
Even if your SSDI is not taxable, you may want to file a federal return. If you had taxes withheld from wages or other income during the year, filing allows you to claim a refund of that money. You may also be able to claim the Earned Income Tax Credit (EITC) if you had wages and meet the income limits, which could result in a refund larger than the taxes you paid.
Filing is also required if you received a Form 1099 from any source — such as interest income, dividend income, or self-employment earnings — even if the amount is small. The IRS matches these forms to tax returns, and not filing when you received a 1099 can trigger a notice.
Some people file voluntarily to establish a record with the IRS, particularly if they expect their income to change in future years or if they want to document their income for other purposes, such as obtaining a loan or proving income for housing information.
State taxes on SSDI benefits
Thirteen states tax SSDI benefits: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The rules vary by state — some tax SSDI the same way the federal government does, while others have different thresholds or tax all SSDI benefits regardless of income level.
If you live in one of these states, you may need to file a state income tax return even if you do not owe federal tax. Some states allow credits or deductions for SSDI that reduce or eliminate the tax owed. Check your state's tax authority website or contact them directly to learn the current rules for your state.
If you moved to a different state during the tax year, you may owe taxes to both your former state and your new state. Each state has its own rules about part-year residents, so this situation requires careful attention to both states' requirements.
Documents you need to file
The Social Security Administration sends you a Form SSA-1099 each January showing your SSDI benefits for the previous year. This form lists the total amount of SSDI you received and is required to file your federal tax return. You should receive it by January 31, though you can request a replacement if it does not arrive.
You will also need any other income documents: W-2 forms from employers, 1099 forms from banks or investment accounts, 1098 forms if you paid mortgage interest or student loan interest, and records of any other income. If you are self-employed, you will need records of your business income and expenses to calculate your net earnings.
Keep copies of all documents you use to file your return, along with a copy of the return itself. The IRS may request documentation years later, and having records makes it easier to respond to any questions.
Frequently Asked Questions
Can I have SSDI taxes withheld from my monthly payment?
Yes. You can request that the Social Security Administration withhold federal income tax from your SSDI benefit each month. Complete Form W-4V and submit it to your local Social Security office or online through your my Social Security account. This does not change the amount you owe — it just spreads the payment across the year instead of paying it all when you file.
What happens if I do not file taxes when I owe them?
The IRS can assess penalties and interest on unpaid taxes. If you owe a small amount, the penalty may be modest, but it grows over time. If you realize you owe taxes for a prior year, file that return as soon as possible — filing late is better than not filing at all, and the IRS sometimes offers payment plans for amounts owed.
Does receiving SSDI affect my ability to claim dependents or other tax credits?
SSDI itself does not prevent you from claiming dependents or other credits. However, your income level — including the combined income calculation — may affect which credits you can claim. The Earned Income Tax Credit, for example, has income limits that vary by filing status and number of dependents.
If I am married and my spouse works, do we file jointly or separately?
You can file jointly or separately, but filing jointly usually results in a lower tax bill. If you file separately, the SSDI taxability threshold drops to $0, meaning all of your SSDI could become taxable. Consult a tax professional if you are unsure which filing status benefits you most.
Where do I report my SSDI on the tax form?
SSDI benefits are reported on Form 1040, lines 5a and 5b. Line 5a shows the total SSDI you received (from Form SSA-1099), and line 5b shows the taxable portion after the IRS calculation. If you use tax software, it will guide you through entering this information correctly.
