Most people on SSDI pay no federal income tax on their benefits

Whether you pay taxes on Social Security Disability Insurance (SSDI) depends on your total income for the year, not just your disability payment. If SSDI is your only income, you almost certainly owe no federal income tax. The tax bill only appears when you have other income — from work, pensions, investments, or rental property — that pushes your combined income above a certain threshold.

The IRS uses a formula called "combined income" to decide how much of your SSDI is taxable. Combined income means your adjusted gross income plus nontaxable interest plus half of your Social Security benefits (including SSDI). Once you know that number, you can look up whether any of your benefits are taxable.

State taxes work differently. Some states tax SSDI the same way the federal government does. Others do not tax it at all, regardless of your income. A few states have their own rules. You need to check your state's tax rules separately.

Key Takeaways

  • If SSDI is your only income, you owe no federal income tax on it.
  • You may owe federal tax if you have other income — from work, pensions, or investments — that raises your combined income above roughly $25,000 (single filers) or $32,000 (married filing jointly).
  • The IRS uses a specific formula to calculate combined income, and you can work through it yourself or ask a tax preparer to do it.
  • State taxes on SSDI vary widely; some states do not tax it at all, while others follow federal rules.
  • You do not have to file a federal tax return if your income is below the filing threshold, even if you receive SSDI.

How the IRS calculates whether your SSDI is taxable

The IRS looks at your combined income, which is not the same as your total income. Combined income includes your adjusted gross income (the income you report on your tax return before deductions), plus any nontaxable interest you earned, plus half of your Social Security benefits.

Here is the actual formula. Add up: (1) your wages, self-employment income, pensions, and taxable interest; (2) any nontaxable interest from municipal bonds or other sources; and (3) half of your SSDI for the year. That total is your combined income.

Once you have that number, the IRS applies a two-tier system. If your combined income is below $25,000 (or $32,000 if you are married filing jointly), none of your SSDI is taxable. If your combined income is between $25,000 and $34,000 (or $32,000 and $44,000 for married filers), up to 50 percent of your benefits may be taxable. If your combined income exceeds $34,000 (or $44,000 for married filers), up to 85 percent of your benefits may be taxable.

The word "may" matters. The actual amount taxed depends on how far above the threshold you go. You do not jump from zero tax to full taxation. A tax preparer or the IRS can walk you through the exact calculation if you think you owe tax.

When you have work income alongside SSDI

If you work while receiving SSDI, your wages count toward your combined income. This is the most common reason SSDI recipients end up owing federal income tax. Even part-time or seasonal work can push your combined income high enough to trigger taxation.

Work income also affects your SSDI payment itself through the Substantial Gainful Activity (SGA) limit. If you earn above that limit (roughly $1,550 per month in 2024, though it changes yearly), Social Security may reduce or stop your SSDI payment. That is a separate issue from taxation, but it matters when you are deciding whether to work.

If you are working and receiving SSDI, you should report your earnings to Social Security and also plan for the possibility of owing income tax. A tax preparer who understands SSDI can help you figure out whether you will owe tax and how much to set aside.

State income tax on SSDI varies widely

Thirty-seven states do not tax SSDI at all, regardless of your income. If you live in one of those states, you owe no state income tax on your disability benefits, period.

Thirteen states do tax SSDI, but most of them follow the federal formula — meaning if your combined income is below the federal threshold, you owe no state tax either. Those states are Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia.

A few states have their own rules. Illinois taxes SSDI only if your income exceeds certain thresholds, but the thresholds differ from the federal ones. You need to check your state's tax authority website or ask a tax preparer familiar with your state's rules.

Whether you have to file a tax return at all

You do not have to file a federal income tax return just because you receive SSDI. The IRS has filing thresholds based on your age and filing status. For 2024, a single person under 65 with less than $14,600 in income does not have to file. If you are 65 or older, the threshold is higher.

However, if you have other income — wages, self-employment income, or investment income — you may have to file even if your SSDI alone would not require it. The threshold applies to your total income, not to SSDI alone.

Even if you are not required to file, you may want to. If you had taxes withheld from wages or other income, filing lets you claim a refund. If you are low-income, you may be able to claim the Earned Income Tax Credit or other credits that require a return.

How to report SSDI on your tax return

SSDI appears on Form SSA-1099-Soc Sec, which Social Security mails to you by January 31 each year. This form shows how much SSDI you received in the previous year. You use this amount to calculate your combined income and determine whether any of your benefits are taxable.

You report the taxable portion of your SSDI on Form 1040 (the main federal income tax return) or Form 1040-SR (for people 65 and older). The IRS worksheet that comes with the form walks you through the combined income calculation step by step.

If you use tax software or hire a tax preparer, you straightforward enter the amount from your SSA-1099 and let the software or preparer do the calculation. Many tax preparers are familiar with SSDI taxation and can handle it quickly.

What happens if you do not pay taxes you owe

If you owe federal income tax on your SSDI and do not pay it, the IRS can offset your future Social Security payments — meaning they deduct the tax debt from your monthly benefit. This is called Treasury offset. The offset can be substantial, so it is worth paying what you owe or setting up a payment plan if you cannot pay in full.

If you think you owe tax but cannot pay, you can contact the IRS to discuss payment options. The IRS offers installment agreements and other arrangements for people who cannot pay their full tax bill at once.

If you are unsure whether you owe tax, a tax preparer or the IRS can help you figure it out. The IRS also has a free tax preparation service for low-income people through the Volunteer Income Tax information (VITA) program.

Frequently Asked Questions

Do I have to pay taxes if SSDI is my only income?

No. If SSDI is your only income, you owe no federal income tax, and you do not have to file a federal return. State taxes vary, but most states also do not tax SSDI.

What counts as "other income" that makes SSDI taxable?

Wages, self-employment income, pensions, taxable interest, capital gains, rental income, and most other sources count. Nontaxable interest (like from municipal bonds) also counts toward your combined income for SSDI tax purposes, even though it is not taxable itself.

If I work part-time, will I owe taxes on my SSDI?

Maybe. It depends on how much you earn. If your combined income (wages plus half your SSDI) stays below $25,000 (or $32,000 if married), you owe no federal tax. A tax preparer can tell you whether your specific situation triggers a tax bill.

Can the IRS take my SSDI payment if I owe back taxes?

Yes, through Treasury offset. The IRS can deduct unpaid federal taxes from your monthly SSDI payment. If you owe taxes, it is worth paying or calling the IRS to set up a payment plan before offset happens.

Where do I find out my state's rules on SSDI taxation?

Contact your state's tax authority or department of revenue. Thirty-seven states do not tax SSDI at all. The others either follow federal rules or have their own thresholds. Your state's website will have the answer.
