Social Security Disability payments are taxable income in some situations, but most people who receive SSDI pay no federal tax on their benefits

Whether you owe federal income tax on your SSDI payments depends on your combined income — a calculation that includes 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 crosses that threshold, you may owe tax on up to 85 percent of your benefits. The threshold is low enough that most SSDI recipients never reach it, but if you have a job, a spouse's income, or other sources of money, you could.

State and local taxes are a separate question. Most states do not tax SSDI, but a few do. You will need to check your state's rules, because federal tax rules do not apply to state income tax.

Key Takeaways

  • You calculate whether SSDI is taxable using combined income, which includes your benefits plus other income sources and tax-exempt interest.
  • If your combined income is below $25,000 (single) or $32,000 (married filing jointly), you owe no federal tax on your SSDI.
  • If your combined income exceeds those thresholds, you may owe tax on up to 50 or 85 percent of your benefits, depending on how far over you go.
  • Most states do not tax SSDI, but you should verify your state's rules because a few do.
  • Social Security sends you a form SSA-1099 each January showing your benefits for tax purposes.

How combined income is calculated

Combined income is not the same as your adjusted gross income. The Social Security Administration adds three things together: your SSDI payments for the year, your other income (wages, self-employment, pensions, interest, dividends, capital gains), and tax-exempt interest (usually from municipal bonds). That total is your combined income.

Some income does not count. Supplemental Security Income (SSI) is not included. Gifts, inheritances, and returns of your own money do not count. Veterans benefits and certain other payments are excluded. The key is whether the IRS would count it as income — if yes, it goes into the combined income calculation.

The two income thresholds and what they mean

The Social Security Administration uses two thresholds. The first is $25,000 for single filers and $32,000 for married couples filing jointly. If your combined income is at or below that number, you owe no federal tax on your SSDI.

If your combined income exceeds the first threshold, you enter a calculation zone. You may owe tax on up to 50 percent of your benefits. The exact amount depends on how far over the threshold you go. If your combined income exceeds $34,000 (single) or $44,000 (married filing jointly) — the second threshold — you may owe tax on up to 85 percent of your benefits.

The math is complex, and the IRS worksheet in Publication 915 walks you through it. Many people use tax software or a tax preparer to handle this, because the calculation involves multiple steps and the thresholds interact with each other in ways that are hard to do by hand.

When you are most likely to owe tax on SSDI

You are most likely to owe tax if you have earned income — wages from a job or self-employment income. Even part-time work can push your combined income over the threshold. A spouse's income counts too if you file jointly, so a working spouse can trigger taxation of your benefits even if you have no income yourself.

Retirement income, pensions, and investment income all count toward combined income. If you receive a pension from a job where you did not pay Social Security taxes, or if you have significant savings generating interest or dividends, your combined income may exceed the threshold.

The thresholds have not changed since 1984, so they have lost purchasing power over time. This means more people reach them each year, even though the dollar amounts stay the same.

How to report SSDI on your tax return

In January, the Social Security Administration sends you a form SSA-1099 showing your SSDI payments for the previous year. You use this form to report your benefits on your federal tax return. If you file electronically, your tax software will prompt you to enter the amount from box 5 of the SSA-1099.

You report SSDI on line 5b of form 1040 (or the equivalent line on other forms if you file a different return type). If you are required to include part of your benefits as taxable income, that amount goes on line 5b as well. The IRS worksheet in Publication 915 tells you how much of your benefits, if any, is taxable.

If you did not receive an SSA-1099 by early February, contact the Social Security Administration to request a replacement. You need it to file accurately, and filing without it can delay your refund or trigger an audit.

State and local taxes on SSDI

Most states do not tax SSDI benefits. However, a small number of states do tax them, and the rules vary. Some states follow the federal calculation; others have their own thresholds or tax all benefits regardless of income. A few states tax SSDI but not regular Social Security retirement benefits, which creates confusion for people receiving both.

You need to check your state's tax rules directly, because state tax does not follow federal rules. Your state tax agency website or a tax preparer familiar with your state can tell you whether you owe state tax on your SSDI. If you live in one of the states that does tax SSDI, you will report it on your state return using a similar process to the federal return.

What happens if you do not report SSDI on your taxes

If you owe federal tax on your SSDI and do not report it, the IRS can assess penalties and interest. The Social Security Administration reports your benefits to the IRS, so the IRS knows you received them. If your return does not include the income you should have reported, the IRS will likely catch it during processing or in a later audit.

If you are unsure whether you owe tax, it is safer to report your benefits and let the calculation determine whether any are taxable. Filing accurately protects you from penalties and keeps your tax record clear. If you cannot afford a tax preparer, the IRS Volunteer Income Tax Assistance (VITA) program offers free tax help to people with low to moderate income.

Frequently Asked Questions

Do I have to pay tax on SSDI if I have no other income?

No. If SSDI is your only income, your combined income is zero, which is well below the first threshold of $25,000. You owe no federal tax on your benefits. You still need to file a return if you have other filing requirements, but your SSDI itself is not taxable.

If I work part-time, will my job push my SSDI into the taxable range?

Possibly. Your combined income includes your wages plus your SSDI. If your wages plus your SSDI total more than $25,000 (or $32,000 if married filing jointly), some of your benefits may be taxable. The exact amount depends on how far over the threshold you go. A tax preparer can calculate this for you based on your specific income.

Does my spouse's income count if we file jointly?

Yes. Combined income for a married couple filing jointly includes both spouses' income plus the SSDI recipient's benefits. If your spouse works or has other income, that counts toward the threshold. This can result in your SSDI being taxable even if you have no income yourself.

What if I disagree with the amount of tax I owe on my SSDI?

Double-check your combined income calculation using the IRS worksheet in Publication 915. If you believe you made an error, you can file an amended return (form 1040-X) within three years. If you are unsure about the calculation, a tax preparer or the IRS can help you verify it.

Can I reduce my SSDI taxes by earning less?

Yes, if you have control over your income. Reducing wages, investment income, or other sources of income can lower your combined income below the threshold, which would eliminate the tax on your benefits. However, this is a personal financial decision that depends on your situation, and you should consider the trade-offs with a financial advisor or tax preparer.
