Most people do not owe state income tax on SSDI, but your state's rules and your total income determine what you actually owe

Social Security Disability Insurance (SSDI) is not taxable income under federal law. The federal government does not tax it, period. But state tax law is separate. Most states also do not tax SSDI. However, a handful of states—currently Kansas, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont—do tax SSDI as income. Whether you owe depends on which state you live in and, in some cases, how much other income you have.

The reason this matters: if you live in a state that taxes SSDI and you do not know it, you might underpay your state taxes and face a bill, penalties, and interest later. If you live in a state that does not tax it, you do not need to report SSDI on your state return at all. The first step is knowing your own state's rule.

Key Takeaways

  • Eight states currently tax SSDI as income: Kansas, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont.
  • If you live in any other state, SSDI is not taxable income and you do not report it on your state tax return.
  • Some states that tax SSDI have income thresholds or exemptions, so you may owe tax only if your total income exceeds a certain amount.
  • Your state tax return instructions or your state's revenue or taxation department website will tell you whether SSDI is taxable in your state and what threshold applies.
  • SSDI is never taxable under federal law, so you never report it on your federal Form 1040 no matter where you live.

Which states tax SSDI and which do not

Eight states currently treat SSDI as taxable income: Kansas, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont. All other states do not tax SSDI. This list can change if a state passes new legislation, so if you live in one of these eight states, confirm the current rule with your state's revenue or taxation department before filing.

In the states that do tax SSDI, the treatment varies. Some tax it the same way they tax other income. Others have thresholds—meaning you owe tax only if your total income (or income from certain sources) exceeds a set amount. For example, one state might tax SSDI only if your combined income from SSDI and other sources exceeds $25,000 per year. Another might have a lower or higher threshold, or none at all. You need to check your specific state's rules, not just the fact that your state is on the list.

How to find out whether your state taxes SSDI

The fastest way is to visit your state's revenue, taxation, or department of revenue website and search for "SSDI" or "Social Security Disability." Most states post this information clearly on their income tax pages. You can also call your state's tax helpline—the number is usually on your state tax return or on the state website.

If you file with a tax preparer or use tax software, the software should prompt you about SSDI based on your state. However, do not assume the software is correct; verify it against your state's official guidance. Your state's written tax instructions for the year you are filing are also reliable—they usually include a section on what income is and is not taxable.

If you receive a state tax return form in the mail, the instructions that come with it will address SSDI. If you file online, the state's website will have the same information. The key is to use your state's official source, not a third-party site, because state law can change year to year.

SSDI and federal taxes: the rule that applies everywhere

SSDI is never taxable under federal law. You do not report it on your federal Form 1040 or any federal return, no matter which state you live in. This is true even if your state taxes it. The federal government treats SSDI as a non-taxable benefit, similar to Supplemental Security Income (SSI).

This means your federal tax situation and your state tax situation are separate. You might owe state tax on SSDI but zero federal tax on it. Or you might live in a state that does not tax SSDI, in which case you report it nowhere. The federal rule is uniform; the state rule is not.

What counts as income when determining whether you owe state tax on SSDI

If your state taxes SSDI, the amount you owe usually depends on your total income for the year. Some states look at your SSDI amount plus any other income—wages, self-employment income, interest, dividends, pensions, or other benefits. Others may have a threshold that applies only to SSDI itself, or they may exclude certain types of income.

For example, if your state taxes SSDI only when combined income exceeds $25,000, and you receive $15,000 in SSDI plus $12,000 in wages, your combined income is $27,000—above the threshold. You would owe tax. But if you received only $15,000 in SSDI and no other income, you would not owe tax in that state.

Other income that might affect your state tax bill includes Supplemental Security Income (SSI), though SSI is also generally not taxable; Veterans Benefits; workers' compensation; and any earned income from work. Check your state's rules to see which types of income count toward the threshold and which are excluded.

How SSDI affects your federal tax situation even though it is not taxable

Although SSDI itself is not taxable income on your federal return, it can affect your federal taxes indirectly. If you have other income—such as wages, self-employment income, or taxable interest—you may owe federal tax on that income. SSDI does not reduce your tax burden, but it also does not increase it.

One exception: if you are married and file jointly, your spouse's income and your SSDI together may push your household income into a higher tax bracket. This is rare and depends on your specific situation, but it is worth understanding if you file jointly and have significant other income.

Additionally, if you receive both SSDI and other Social Security benefits (such as retirement or survivor benefits), the rules for taxing the other benefits are different. Up to 85 percent of those other benefits may be taxable depending on your combined income. But pure SSDI is never taxable at the federal level.

What to do if you live in a state that taxes SSDI

If you live in one of the eight states that tax SSDI, report it on your state tax return according to your state's instructions. Most states have a line or section on the return where you enter SSDI income. You will need your SSDI statement or your Social Security Administration (SSA) records to know the exact amount you received during the tax year.

You can request a statement of your SSDI benefits from the SSA by creating an account on ssa.gov, calling 1-800-772-1213, or visiting your local Social Security office. The statement will show how much you received each month. Add up the months you received benefits during the tax year to get your total SSDI income for that year.

If you use tax software or a tax preparer, tell them you live in a state that taxes SSDI and provide your SSDI amount. Make sure the software or preparer reports it correctly on your state return. Do not assume it will be handled automatically—verify it before you file.

Frequently Asked Questions

Do I have to report SSDI on my federal tax return?

No. SSDI is not taxable under federal law, so you do not report it on your Form 1040 or any federal return. You only report it if you live in one of the eight states that tax it, and then only on your state return.

What if I move to a different state—do I owe back taxes on SSDI?

No. You owe state tax only for the year and state in which you lived. If you moved from a state that taxes SSDI to one that does not, you do not owe tax on SSDI for the new state going forward. If you moved the other direction, you would owe tax on SSDI only for the months you lived in the taxing state.

If my state taxes SSDI, do I have to file a state return even if I have no other income?

That depends on your state's filing threshold. Some states require you to file if your SSDI income alone exceeds a certain amount. Others do not. Check your state's tax instructions or call your state's tax helpline to find out whether you must file.

Can I deduct anything from my SSDI income on my state return?

That depends on your state's rules. Some states allow standard deductions or other deductions that reduce your taxable SSDI income. Others do not. Your state's tax instructions will explain what deductions, if any, explore to SSDI income.

What if I disagree with my state's decision to tax SSDI?

You can contact your state legislator or your state's disability advocacy organizations to voice your concern. However, you must still pay the tax owed under current law. If you believe your state tax bill is calculated incorrectly, you can file a protest or appeal with your state's revenue department according to the process outlined in your state's tax instructions.
