SSDI is taxed the same way in New Jersey as everywhere else in the United States

New Jersey does not have a separate state tax on SSDI benefits. Whether your SSDI is taxable depends on your total income for the year, not on where you live. The federal government decides if you owe tax on your benefits based on a calculation called combined income, which includes your SSDI, wages, interest, and other money you received.

New Jersey residents do pay state income tax on wages and other earned income, but SSDI is treated differently at the state level. If the federal government says your SSDI is not taxable, New Jersey will not tax it either. If the federal government says part of your SSDI is taxable, you report that same amount to New Jersey.

The real question for you is whether your SSDI crosses the federal threshold that makes it taxable. That threshold is the same whether you live in New Jersey, California, or anywhere else.

Key Takeaways

  • New Jersey does not tax SSDI benefits separately—you follow federal rules for whether any of your SSDI is taxable.
  • Your SSDI becomes taxable only if your combined income (SSDI plus other income) exceeds a federal threshold: $25,000 for single filers or $32,000 for married couples filing jointly.
  • If you work while receiving SSDI, your wages count toward the combined income calculation, which may push you over the threshold.
  • You report any taxable SSDI on your federal tax return; New Jersey follows the same information.

How the federal combined income calculation works

The IRS uses a specific formula to decide if your SSDI is taxable. You add up your adjusted gross income, tax-exempt interest, and half of your SSDI benefits. That total is your combined income. If it exceeds $25,000 (single) or $32,000 (married filing jointly), some of your SSDI becomes taxable.

The thresholds have not changed since 1984. They do not adjust for inflation, which means more people cross them each year as wages and other income rise. If you are close to the threshold, even a small amount of additional income—a part-time job, a pension, interest from savings—can push you over.

New Jersey residents follow this same federal calculation. There is no separate New Jersey threshold or different rule. Once you know whether you owe federal tax on your SSDI, you know the answer for the state as well.

What counts as income in the combined income calculation

Combined income includes wages from work, self-employment income, pensions, annuities, interest, dividends, capital gains, and rental income. It also includes half of your SSDI benefit amount. Some types of income are excluded—for example, Supplemental Security Income (SSI) does not count, and neither do certain veterans' benefits.

If you are working while receiving SSDI, your wages are the most common reason your combined income rises above the threshold. Even part-time work can matter. A job that pays $10,000 a year, combined with your SSDI and any other income, might be enough to make your SSDI taxable.

Tax-exempt interest (such as interest from municipal bonds) still counts toward combined income for SSDI purposes, even though it is not taxable income for other purposes. This is a common surprise for people who think tax-exempt means it does not count anywhere.

How much of your SSDI becomes taxable

If your combined income exceeds the threshold, not all of your SSDI becomes taxable—only a portion of it. The IRS uses a two-tier system. Up to 85 percent of your benefits can be taxable, but most people pay tax on a smaller amount.

The exact calculation depends on how far above the threshold you are. If you are just barely over, you might owe tax on 50 percent of the excess. If you are well above, you might owe tax on up to 85 percent of your benefits. The IRS publishes a worksheet each year to help you calculate this, and the Social Security Administration includes it in Publication 915.

Because the calculation is complex, many people use tax software or a tax preparer to figure out the correct amount. If you do your own taxes, the IRS worksheet walks through the steps, but it requires careful attention to detail.

Filing taxes in New Jersey when you receive SSDI

You file your federal tax return the same way whether you live in New Jersey or elsewhere. You report any taxable SSDI on line 5b of Form 1040. Social Security sends you a Form SSA-1099 each January showing your total benefits for the previous year; you use this to complete your return.

New Jersey requires you to file a state income tax return if your income exceeds the state threshold. For 2024, that threshold is $10,000 for single filers and $20,000 for married couples filing jointly. If your only income is SSDI and it is below that threshold, you may not need to file a New Jersey return—but if you have wages or other income, you likely will.

When you file your New Jersey return, you report the same taxable SSDI amount that you reported to the federal government. New Jersey does not recalculate or explore a different rule. You can file both returns electronically through the IRS and New Jersey's tax filing systems, or on paper.

What happens if you work while receiving SSDI

Work incentives exist under SSDI to help you earn money without losing your benefits when ready. The Substantial Gainful Activity (SGA) threshold for 2024 is $1,550 per month. If you earn less than that, SSDI does not count it as work that would end your benefits. However, that income still counts toward the combined income calculation for tax purposes.

This means you can earn money, keep your SSDI benefits, and still owe tax on part of your SSDI if your combined income is high enough. The work incentive protects your benefits; it does not protect you from taxation. Many people are surprised to learn these are separate rules.

If you earn more than SGA, your benefits may stop, but you still report the income on your tax return. New Jersey taxes wages the same way any state does—you owe state income tax on earned income regardless of your SSDI status.

Planning ahead if you are close to the tax threshold

If your combined income is near $25,000 (or $32,000 if married), small decisions about income can matter. Delaying a bonus, timing a pension distribution, or managing when you sell investments might affect whether you cross the threshold. This is not tax avoidance—it is legitimate tax planning that many people do.

Some people in this situation work with a tax preparer or financial advisor to understand the impact of additional income before they earn it. For example, if you are considering taking a part-time job, you can calculate whether the wages will push you over the threshold and how much additional tax you would owe. Sometimes the math shows it is worth it; sometimes it shows you would keep more money by not working.

New Jersey does not offer special deductions or credits for SSDI recipients that would lower your taxable income. Your options are the same as for any taxpayer: standard deduction, itemized deductions if they explore to you, and any other credits you may be may have access to to based on your situation.

Frequently Asked Questions

Do I have to file a New Jersey tax return if I only receive SSDI?

Only if your total income exceeds the state threshold: $10,000 for single filers or $20,000 for married couples filing jointly. If SSDI is your only income and it is below that amount, you do not have to file a New Jersey return. However, if you have wages or other income, you likely will need to file.

Can I reduce my taxable SSDI by making charitable donations?

Charitable donations reduce your overall taxable income, but they do not change the combined income calculation that determines whether your SSDI is taxable in the first place. You would need to reduce your combined income below the threshold to avoid SSDI taxation entirely, which is difficult to do through deductions alone.

What if I disagree with the amount of SSDI the IRS says is taxable?

You can recalculate using the IRS worksheet in Publication 915 to make sure no math errors were made. If you still disagree, you can file an amended return (Form 1040-X) with a written explanation. If the issue involves how Social Security calculated your benefit amount, contact Social Security directly rather than the IRS.

Does New Jersey offer any tax credits for people receiving SSDI?

New Jersey does not have a credit specifically for SSDI recipients. You may be may have access to to other credits based on your age, income, or dependents—such as the Earned Income Tax Credit if you work—but these are the same credits available to any taxpayer, not specific to SSDI.

If my SSDI is not taxable federally, do I still have to report it on my New Jersey return?

No. If your combined income is below the federal threshold and none of your SSDI is taxable federally, you do not report it on your New Jersey return either. New Jersey follows the federal information exactly.
