Social Security Disability Benefits Are Usually Not Taxable
Most people who receive Social Security Disability Insurance (SSDI) do not pay federal income tax on those benefits. The money you get each month is not taxed the way wages from a job are taxed. However, there is a specific situation where part of your benefits can become taxable, and it depends on your other income.
The rule is straightforward: if SSDI is your only income, you owe no federal tax on it. But if you have other income—from work, investments, pensions, or other sources—some of your SSDI may be taxable. This is called "combined income," and it is the only thing that determines whether you owe tax.
Key Takeaways
- SSDI benefits are tax-free unless you have other income that pushes your combined income above a certain threshold.
- Combined income means your SSDI plus half of your SSDI plus any other income you received that year.
- If your combined income exceeds $25,000 (single) or $32,000 (married filing jointly), up to 85 percent of your benefits may be taxable.
- You do not have to file a tax return if SSDI is your only income, even if you receive other forms of Social Security.
- State taxes on SSDI vary by state—some states tax it, most do not, and you need to check your state's rules.
How Combined Income Is Calculated
The Social Security Administration uses a specific formula to determine whether your SSDI is taxable. Combined income is calculated as: your adjusted gross income (AGI) plus nontaxable interest plus half of your SSDI benefits. This number is what the IRS compares against the thresholds.
For example, if you received $15,000 in SSDI and had $12,000 in income from part-time work, your combined income would be $12,000 plus half of $15,000 (which is $7,500), for a total of $19,500. If you are single, this is below the $25,000 threshold, so none of your SSDI would be taxable.
The thresholds are the same every year and do not adjust for inflation. For single filers, the first threshold is $25,000. For married couples filing jointly, it is $32,000. For married people filing separately, it is $0—meaning any combined income at all can trigger taxation.
When Part of Your SSDI Becomes Taxable
If your combined income exceeds the threshold for your filing status, the IRS taxes either 50 percent or 85 percent of your benefits, depending on how far above the threshold you are. The calculation is complex, but the result is that you never pay tax on more than 85 percent of what you received.
Reaching the first threshold ($25,000 for single filers) means up to 50 percent of your benefits may be taxable. Reaching the second threshold ($34,000 for single filers) means up to 85 percent may be taxable. Most people whose combined income exceeds these thresholds still pay tax on only a portion of their benefits, not all of them.
The IRS publishes a worksheet each year to help you calculate the exact amount. If you work with a tax preparer or use tax software, they can run this calculation for you. The Social Security Administration also sends Form SSA-1099 each January, which shows the total SSDI you received the previous year.
Who Must File a Tax Return
You are required to file a federal tax return if your combined income exceeds the threshold for your filing status. If SSDI is your only income and you are single, you do not have to file—your combined income is $0, which is well below $25,000.
However, if you have any other income—even $1 from a part-time job, interest from a savings account, or a pension—you may need to file. The threshold for filing is different from the threshold for taxation. For 2024, a single person under 65 must file if their gross income is $14,600 or more. If you are 65 or older, the threshold is $18,350.
Even if you are not required to file, you may want to file anyway. If your employer withheld taxes from your paycheck, filing allows you to claim a refund. If you had other tax credits available to you, filing lets you claim them.
State Taxes on SSDI
Federal tax rules do not explore to state income tax. Most states do not tax SSDI at all, but some do. The states that tax SSDI benefits are Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont. Even in these states, the rules vary—some tax only a portion, and some have income thresholds of their own.
If you live in one of these states, you will need to check your state's tax rules or contact your state tax authority to understand what you owe. A tax preparer in your state can also tell you whether your SSDI is taxable under state law. The Social Security Administration does not handle state taxes, so the federal rule that SSDI is usually not taxable does not automatically explore at the state level.
What to Do If You Owe Tax on SSDI
If your combined income is high enough that part of your SSDI becomes taxable, you have two options: pay the tax when you file your return, or ask Social Security to withhold taxes from your monthly benefit payment.
To request withholding, you fill out Form W-4V and send it to your local Social Security office. You can choose to have 7, 10, 12, or 22 percent of your monthly benefit withheld. This is voluntary, but it can help you avoid a large tax bill at the end of the year. If you choose not to withhold, you are responsible for paying any tax owed when you file.
Keep in mind that withholding reduces the amount of money you receive each month. If you are living on a tight budget, this may not be practical. Many people choose to set aside money each month instead and pay the tax bill when they file their return.
How Work Affects Your SSDI and Taxes
If you are working while receiving SSDI, your wages count as part of your combined income for tax purposes. This means working can push you over the threshold and make your SSDI taxable, even if the work income itself is small.
Work also affects SSDI in a separate way: if you earn above the substantial gainful activity (SGA) limit, Social Security may determine that you are no longer disabled and stop your benefits. For 2024, the SGA limit is $1,550 per month (or $2,590 if you are blind). This is different from the tax calculation, but both happen at the same time if you are working.
Before you start working, talk to a Social Security representative about how it will affect your benefits and your taxes. Social Security offers a work incentive program called Plan to Achieve Self-Support (PASS) that can help you keep more of your earnings without losing benefits, but you have to set it up in advance.
Frequently Asked Questions
Do I have to file a tax return if I only get SSDI?
No. If SSDI is your only income, you do not have to file a federal tax return, and you do not owe any tax on your benefits. You only need to file if you have other income that pushes your combined income above the threshold for your filing status.
What if I get both SSDI and SSI?
Supplemental Security Income (SSI) is never taxable, but SSDI can be. If you receive both, only the SSDI portion is included in the combined income calculation. SSI does not count toward the thresholds that make SSDI taxable.
Can I reduce my taxes by not working?
If work is pushing your combined income over the threshold, reducing work hours or stopping work would lower your combined income and reduce or eliminate the tax on your SSDI. However, this decision affects your overall finances, not just taxes. Talk to a financial advisor or Social Security representative before making changes to your work.
What happens if I do not pay the tax I owe?
If you owe tax and do not pay it, the IRS can charge penalties and interest, and the debt can grow over time. If you cannot pay the full amount, you can contact the IRS to set up a payment plan. It is better to file your return and work out a payment arrangement than to ignore the debt.
Do I need to report my SSDI to the IRS myself?
No. Social Security sends Form SSA-1099 to both you and the IRS each January, showing how much SSDI you received. You do not have to report it separately. When you file your tax return, you include the information from the SSA-1099.
