Whether you pay tax on disability depends on your total income and filing status

Social Security Disability Insurance (SSDI) benefits may be taxable, but only if your combined income exceeds a threshold set by the IRS. The tax applies only to the portion of your benefits above that threshold, and many people with SSDI pay no federal income tax at all. The rules are the same as those for Social Security retirement benefits — the IRS does not treat disability differently once you are receiving it.

Your "combined income" for this calculation includes your SSDI benefits, wages, self-employment income, interest, dividends, and certain other sources. The IRS uses a specific formula to determine how much of your benefit is taxable. If your combined income is below the threshold for your filing status, you owe nothing on your SSDI. If it exceeds the threshold, you may owe tax on up to 85 percent of your benefits.

Key Takeaways

  • SSDI is taxable only if your combined income (benefits plus other earnings) exceeds $25,000 for single filers or $32,000 for married couples filing jointly.
  • If you are taxed on SSDI, the IRS taxes only the amount above the threshold, up to a maximum of 85 percent of your benefits.
  • You can request that the Social Security Administration withhold federal income tax directly from your SSDI payment to avoid a tax bill at filing time.
  • State income tax on SSDI varies by state — some states do not tax SSDI at all, while others follow federal rules.
  • You must report SSDI on your tax return even if none of it is taxable, because the IRS uses that information to calculate the taxable portion.

The income thresholds that determine whether SSDI is taxable

The IRS sets two thresholds. If your combined income falls below the first threshold, none of your SSDI is taxable. If it exceeds the first threshold but stays below the second, up to 50 percent of your benefits may be taxable. If it exceeds the second threshold, up to 85 percent may be taxable.

For 2024, the first threshold is $25,000 for single filers, $32,000 for married couples filing jointly, and $0 for married couples filing separately (with limited exceptions). The second threshold is $34,000 for single filers and $44,000 for married couples filing jointly. These thresholds do not change year to year — Congress set them in 1983 and has not adjusted them since.

Combined income includes your SSDI benefit amount plus half of your SSDI benefits plus any other income. This creates a formula that can feel circular: your SSDI counts toward the threshold that determines whether your SSDI is taxable. If you have no other income, you would need SSDI of more than $50,000 per year to exceed the first threshold — a rare situation.

How the IRS calculates the taxable portion of your benefits

The calculation has two steps. First, the IRS determines how much your combined income exceeds the first threshold. Then it applies a formula that taxes either 50 percent or 85 percent of that excess, depending on how far above the second threshold you are.

Example: You are single and receive $18,000 in SSDI per year. You also earn $10,000 from part-time work. Your combined income is $10,000 plus half of $18,000 ($9,000), which equals $19,000. This is below the first threshold of $25,000, so none of your SSDI is taxable.

Another example: You are single and receive $18,000 in SSDI per year and earn $20,000 from work. Your combined income is $20,000 plus $9,000 (half your benefit), which equals $29,000. This exceeds the first threshold of $25,000 by $4,000. You would owe tax on the lesser of (a) 50 percent of the excess ($2,000) or (b) 50 percent of your benefits ($9,000). In this case, $2,000 of your SSDI is taxable.

Requesting tax withholding from your SSDI payment

You can ask the Social Security Administration to withhold federal income tax directly from your monthly SSDI payment. This prevents a large tax bill when you file your return and is often simpler than making quarterly estimated tax payments.

To request withholding, complete Form W-4V (Voluntary Withholding Request) and submit it to your local Social Security office, by mail, or online through your my Social Security account. You can choose to withhold 7, 10, 15, or 22 percent of your benefit. The amount withheld is sent to the IRS and credited toward your annual tax liability.

You can change or stop withholding at any time by submitting a new Form W-4V. If you expect to owe little or no tax, you may choose not to withhold and instead file your return without prepayment. If you expect to owe a large amount, you might withhold more than the standard percentages by filing Form W-4V and requesting a specific dollar amount.

State income tax on SSDI varies widely

Thirteen states do not tax SSDI at all: Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Mississippi, Missouri, Oklahoma, and Pennsylvania. The remaining states either follow the federal taxability rules or have their own thresholds and formulas.

Some states with income tax — such as California, New York, and Texas — do not tax SSDI even though they tax other income. Others, such as Colorado and Minnesota, tax SSDI the same way the federal government does. A few states have thresholds that differ from the federal thresholds, making it possible to owe state tax on SSDI while owing no federal tax, or vice versa.

You should check your state's tax authority website or speak with a tax professional to understand your state's rules. State tax treatment of SSDI can change, so it is worth verifying the current rule in your state before filing.

Reporting SSDI on your tax return

The Social Security Administration sends you a Form SSA-1099 each January showing the total SSDI you received in the prior year. You must report this amount on your federal tax return even if none of it is taxable. The IRS uses the reported amount to verify that you have calculated the taxable portion correctly.

On your federal return, you report SSDI on Form 1040, line 5b. You also complete a worksheet (included in the Form 1040 instructions) that calculates your combined income and determines the taxable portion. If you use tax software, the software usually walks you through this calculation.

If you file a state return, you report SSDI according to your state's rules. Some states require you to report the full amount; others require you to report only the taxable portion. Check your state's tax form instructions or contact your state tax authority.

What happens if you do not report SSDI or underreport your income

The IRS receives a copy of your Form SSA-1099, so it knows how much SSDI you received. If you do not report it on your return, the IRS will likely send you a notice asking why. Underreporting income can result in penalties, interest, and in some cases criminal charges if the underreporting is deliberate and substantial.

If you made a mistake on a prior return, you can file an amended return using Form 1040-X. The IRS generally allows you to amend a return within three years of the original filing date. Filing an amended return voluntarily, before the IRS contacts you, often results in lower penalties than if the IRS discovers the error first.

Frequently Asked Questions

Can I reduce my taxable SSDI by reducing my work income?

Yes. Because combined income determines whether SSDI is taxable, reducing wages or self-employment income can lower or eliminate the tax. If you are close to a threshold, earning slightly less might move you below it and make your SSDI tax-free. However, you should consider the trade-off: earning less reduces your total income and may affect other benefits like Medicare or housing support.

Do I have to file a tax return if my only income is SSDI?

Not necessarily. If SSDI is your only income and it is below the filing threshold for your age and filing status, you are not required to file. However, if you had federal income tax withheld from your SSDI, you should file a return to claim a refund of the withheld amount.

What if I am married and my spouse works?

Your spouse's income counts toward your combined income for the purpose of determining whether your SSDI is taxable. If you file jointly, you use the married filing jointly thresholds ($32,000 and $44,000). If you file separately, the thresholds are much lower and the rules are more complex — you may want to consult a tax professional.

Does SSDI count as income for Medicaid or other means-tested programs?

Yes. SSDI counts as income for Medicaid, Supplemental Security Income (SSI), and other means-tested programs. The income limits for these programs are separate from the tax thresholds, and they may be lower. Receiving SSDI can affect your may be able to access for other information.

Can I get a refund if too much tax was withheld from my SSDI?

Yes. If you had federal income tax withheld and you owe less tax than was withheld, you will receive a refund when you file your return. The refund is calculated based on your actual tax liability, which depends on your total income and deductions. File your return as soon as possible after receiving your Form SSA-1099 to claim the refund.
