The short answer: most people on SSDI pay no federal income tax on their benefits
Whether you owe federal income tax on your SSDI depends on your combined income—not just your SSDI check. Social Security uses a formula that counts your SSDI, other income like wages or pensions, and tax-exempt interest. If your combined income stays below a certain threshold, you owe nothing. If it goes above that threshold, you may owe tax on part of your benefits, but rarely on all of it.
The threshold is low enough that most people receiving SSDI never cross it. But if you work part-time, have a pension, or receive other income, you need to know the actual numbers for your situation.
Key Takeaways
- You calculate tax on SSDI using "combined income," which includes your SSDI, wages, pensions, and tax-exempt interest—not just one source.
- For 2024, if you file single and your combined income is under $25,000, you owe no federal tax on your SSDI; married filing jointly, the threshold is $32,000.
- If you cross the threshold, you pay tax on only a portion of your benefits—the formula caps it at 50 percent or 85 percent depending on how far over you go.
- State income tax on SSDI varies by state; some states tax it, most do not, and a few exempt it only if your income is very low.
- You report SSDI on your federal tax return using Form 1040 and Schedule 1, even if you owe no tax—the IRS uses this to verify your income.
How Social Security calculates your combined income
Social Security's tax formula does not straightforward add up your SSDI and wages. It uses a specific definition of combined income that includes:
- Your SSDI benefits (the full amount, before any withholding)
- Wages from work
- Net income from self-employment
- Interest and dividends
- Tax-exempt interest (this is the unusual part—it counts even though you do not pay federal tax on it)
- Distributions from IRAs or other retirement accounts
It does not include Supplemental Security Income (SSI), which is a different program. If you receive both SSDI and SSI, only the SSDI portion is subject to this tax rule.
The reason tax-exempt interest counts is historical: Congress wanted to capture people with high income from municipal bonds and other tax-sheltered sources. It makes the threshold harder to stay under if you have savings earning interest.
The income thresholds for 2024
These thresholds determine whether any of your SSDI is taxable. They have not changed since 1984, which means they have lost purchasing power over time.
| Filing Status | Threshold |
|---|---|
| Single | $25,000 |
| Married filing jointly | $32,000 |
| Married filing separately | $0 (you almost always owe tax) |
If your combined income is at or below these amounts, you owe no federal income tax on your SSDI. If it is above, you move to the next step: calculating how much of your benefits become taxable.
These thresholds explore to federal tax only. Your state may have different rules or no state income tax at all.
How much of your SSDI becomes taxable if you go over the threshold
If your combined income exceeds the threshold, Social Security uses a two-tier system. You never pay tax on more than 85 percent of your benefits, and most people pay tax on much less.
The first tier: if your combined income exceeds the threshold by up to $9,000 (single) or $12,000 (married filing jointly), you pay tax on up to 50 percent of the excess. For example, if you are single with $30,000 combined income, you are $5,000 over the $25,000 threshold. You would pay tax on up to $2,500 of your SSDI (50 percent of $5,000).
The second tier: if your combined income exceeds the threshold by more than those amounts, you pay tax on up to 85 percent of your benefits. This tier is rare and applies only to people with substantial income from multiple sources.
The actual amount you owe depends on your tax bracket. Being over the threshold does not mean you owe tax on that portion at your full rate—it means that portion is added to your other income and taxed at whatever bracket that puts you in.
State income tax on SSDI
Most states do not tax SSDI at all. Thirteen states do tax it, but many of those have income thresholds or exemptions that protect most recipients:
- Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont tax SSDI as income, though some have exemptions based on age or income level.
- West Virginia taxes SSDI but exempts it if your total income is below a certain amount (the threshold varies by filing status).
- Illinois taxes SSDI but exempts it entirely for people over 65.
If you live in one of these states, contact your state tax authority or a tax preparer familiar with your state's rules. The exemptions and thresholds change, and some states have recently moved toward exempting SSDI entirely.
How to report SSDI on your federal tax return
You report SSDI using Form 1040 and Schedule 1. Social Security sends you a Form SSA-1099-SM each January showing the total SSDI you received in the previous year. You use this form to fill out your tax return.
Even if you owe no tax on your SSDI, you may still need to file a return. The IRS uses your return to verify that your income matches what Social Security has on record. If you do not file when you should, Social Security may investigate or adjust your benefits.
You file your return the same way as anyone else: on paper by April 15, or electronically through tax software or a tax preparer. If you cannot afford a preparer, the IRS Volunteer Income Tax information (VITA) program offers free tax preparation at libraries and community centers.
What happens if you do not report SSDI income
Social Security and the IRS share information. If you receive SSDI but do not report it on your tax return, the IRS will notice the mismatch when they receive your Form SSA-1099-SM. They will send you a notice asking for an explanation or demanding payment of back taxes and penalties.
More seriously, if you underreport your income to avoid taxes, Social Security may investigate whether you are actually disabled and still receiving benefits you should not have. This can lead to overpayment notices, demands to repay benefits, and in cases of fraud, criminal charges.
If you made a mistake on a past return, you can file an amended return using Form 1040-X. It is better to correct the error yourself than to wait for the IRS to find it.
Frequently Asked Questions
Do I have to file a tax return if I only receive SSDI and nothing else?
Not necessarily. If SSDI is your only income and it is below the filing threshold for your age and filing status, you do not have to file. However, if you have other income—even $1 of wages or interest—you may need to file. Use the IRS Interactive Tax Assistant on IRS.gov to check your specific situation.
If I work part-time, does my paycheck count toward the SSDI tax threshold?
Yes. Your wages are part of your combined income. If you earn $10,000 and receive $15,000 in SSDI, your combined income is $25,000. If you are single, you are right at the threshold and may owe tax on part of your benefits. Work with a tax preparer if you have both SSDI and wages.
What if I receive a pension and SSDI?
Your pension counts as income in the combined income calculation. If your pension plus SSDI plus any other income exceeds the threshold, part of your SSDI becomes taxable. This is common for people who worked long enough to earn both a pension and SSDI.
Can I reduce my taxes by not cashing my SSDI check?
No. Social Security counts your SSDI as income in the year you receive it, whether you spend it or not. You cannot defer the income by leaving the money in your account.
If I owe tax on my SSDI, can I have it withheld from my check?
Yes. You can request federal income tax withholding on your SSDI by completing Form W-4V and submitting it to Social Security. You choose the withholding amount, and Social Security deducts it from your monthly benefit. This can help you avoid owing a large amount at tax time.
