SSDI is taxable income, but only if your total income crosses a threshold
You may owe federal income tax on your Social Security Disability Insurance (SSDI) benefits, but most people who receive SSDI alone do not. The tax depends on your combined income—not just your SSDI check, but also wages, interest, pensions, and other money you receive in the same year.
The Social Security Administration (SSA) uses a formula called provisional income to determine whether your benefits are taxable. If your provisional income stays below a certain threshold, you owe no federal tax on your SSDI. If it crosses that threshold, a portion of your benefits becomes taxable.
State taxes are separate. Some states tax SSDI; most do not. You need to check your own state's rules because federal tax rules do not explore to state income tax.
Key Takeaways
- You calculate whether SSDI is taxable by adding your SSDI amount to half your SSDI plus all other income sources, then comparing that total to a threshold that has not changed since 1984.
- The federal thresholds are $25,000 for single filers and $32,000 for married couples filing jointly; if your provisional income is below these amounts, you owe no federal tax on SSDI.
- If you have other income (wages, pensions, interest, rental income), that income is what usually pushes you over the threshold, not the SSDI itself.
- Most states do not tax SSDI at all, but a few do; you must check your state's tax rules separately from federal rules.
- The SSA sends you a form SSA-1099 each January showing how much SSDI you received; you use this to file your tax return.
How the provisional income formula works
The SSA uses a specific calculation to decide if any of your SSDI is taxable. This is called provisional income, and it is not the same as your actual income.
To find your provisional income, add these three things together:
- Your adjusted gross income (AGI) from all sources except SSDI
- Tax-exempt interest (interest from municipal bonds, for example)
- Half of your SSDI benefits for the year
Once you have that total, compare it to the threshold for your filing status. If your provisional income is at or below the threshold, you owe no federal tax on your SSDI. If it is above the threshold, a portion of your benefits becomes taxable.
Example: You receive $15,000 in SSDI and $12,000 in wages. Half your SSDI is $7,500. Your provisional income is $12,000 (wages) + $7,500 (half SSDI) = $19,500. If you file as single, the threshold is $25,000. Since $19,500 is below $25,000, none of your SSDI is taxable.
The federal income thresholds that determine taxability
The thresholds have been the same since 1984 and do not adjust for inflation. This means more people cross the threshold each year as wages and other income rise.
| Filing Status | First Threshold | Second Threshold |
|---|---|---|
| Single | $25,000 | $34,000 |
| Married filing jointly | $32,000 | $44,000 |
| Married filing separately | $0 | $0 |
If your provisional income falls between the first and second threshold, up to 50 percent of your SSDI can be taxed. If it exceeds the second threshold, up to 85 percent of your SSDI can be taxed. The exact amount depends on how far above the threshold you are.
Married couples filing separately almost always have SSDI taxed, because the first threshold is $0. This filing status is rarely used for this reason.
When other income pushes you into taxable territory
Most people who owe tax on SSDI do not owe it because of the SSDI itself—they owe it because they have other income. Wages, pensions, interest, rental income, and self-employment income all count toward your provisional income and can push you over the threshold.
If you work while receiving SSDI, your wages are added to your provisional income in full. This is the most common reason SSDI becomes taxable. Even part-time work or a small pension can cross the threshold if your SSDI is substantial.
Tax-exempt interest—money from municipal bonds or certain other sources—also counts in the provisional income calculation, even though it is not taxable itself. This catches some people by surprise.
If you are close to the threshold, you may want to talk to a tax preparer about whether certain deductions or filing choices could lower your provisional income. Some people benefit from filing as head of household instead of single, for example.
How to report SSDI on your tax return
Each January, the SSA mails you a form SSA-1099 showing how much SSDI you received in the previous year. This form goes to you and to the Internal Revenue Service (IRS). You use it to file your federal tax return.
If you received SSDI for only part of the year, the SSA-1099 shows only the amount you actually received. If you did not receive SSDI at all in a year, you will not get an SSA-1099 for that year.
When you file your return, you enter the SSDI amount from your SSA-1099 on the appropriate line. If your provisional income is below the threshold, you report the SSDI but do not owe tax on it. If it is above the threshold, you calculate the taxable portion using the IRS worksheet and report that amount.
The IRS provides a worksheet in the instructions for Form 1040 to help you calculate how much SSDI is taxable. You can also use IRS Publication 915, which walks through the calculation step by step.
State income tax rules for SSDI
Most states do not tax SSDI benefits at all. However, a small number of states do tax SSDI, and the rules vary by state.
States that currently tax SSDI include Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont. Some of these states have thresholds similar to the federal thresholds; others tax SSDI differently. A few states tax SSDI only for higher-income recipients.
If you live in one of these states, you will need to file a state income tax return and report your SSDI. The state's tax rules may differ from the federal calculation, so you cannot assume that if you do not owe federal tax, you do not owe state tax.
Check your state's department of revenue website or talk to a tax preparer who knows your state's rules. State rules change, and some states have modified their SSDI tax treatment in recent years.
What to do if you receive a tax bill for SSDI
If you owe tax on SSDI, you can pay it when you file your return, or you can arrange a payment plan with the IRS if you cannot pay in full. You can also have the IRS withhold taxes from your SSDI check each month so you do not owe a large amount at tax time.
To set up withholding, you file Form W-4V with the SSA. You choose to have 7, 10, 15, or 25 percent of your SSDI withheld for federal taxes. This reduces your monthly check but means you will owe less (or nothing) when you file your return.
If you did not withhold taxes and now owe a bill, you can still file Form W-4V to start withholding going forward. This will not pay your past tax bill, but it will reduce what you owe next year.
If you believe you were taxed incorrectly, you can file an amended return using Form 1040-X. You have three years from the original due date to amend a return and claim a refund.
Frequently Asked Questions
Do I have to file a tax return if I only receive SSDI?
No. If SSDI is your only income and your provisional income is below the threshold, you have no tax filing requirement. However, you may want to file anyway if you are due a refund from taxes withheld or if you may have access to for the Earned Income Tax Credit or other refundable credits.
What if I work part-time and receive SSDI—will I owe tax?
Possibly. Your wages plus half your SSDI plus any other income must be compared to the threshold. If the total is above $25,000 (single) or $32,000 (married filing jointly), some of your SSDI becomes taxable. A tax preparer can tell you whether you will owe based on your specific situation.
Can I reduce my SSDI taxes by changing when I receive income?
Not easily. Provisional income is calculated for the calendar year, so you cannot shift income between years without affecting your SSDI tax status. However, you may be able to time certain deductions or charitable contributions to lower your AGI. Talk to a tax professional about your specific circumstances.
If I do not owe federal tax on SSDI, do I owe state tax?
It depends on your state. Most states do not tax SSDI, but about a dozen do. Check your state's tax rules or contact your state department of revenue. Federal and state thresholds are different, so you could owe state tax even if you do not owe federal tax.
What happens if I do not report SSDI on my tax return?
The IRS receives a copy of your SSA-1099, so they know you received SSDI. If you do not report it and you owe tax on it, the IRS will likely send you a notice. It is better to file a return and report the income, even if you believe none of it is taxable, to avoid penalties and interest.
