New Jersey Paycheck Calculator
New Jersey runs graduated schedules from 1.4% to 10.75%, exempts the lowest earners entirely, and treats pre-tax benefits differently from the IRS — your 401(k) reduces New Jersey wages, but your health premium usually does not. This calculator applies all of it.

How New Jersey reads your pay
New Jersey's schedules have been fixed in statute since 2020: seven bands for a single filer (1.4% up to $20,000, rising through 5.525% and 6.37%, to 10.75% above $1 million) and eight for joint filers and heads of household, whose middle bands are wider. The state prints each band as "multiply by the rate, subtract the printed amount," and this calculator carries the schedules in exactly that form, so the arithmetic in the results matches the printed page at the Division of Taxation.
Two reliefs matter at paycheck scale. Exemptions: $1,000 for you, $1,000 for a spouse on a joint return, $1,500 per dependent — no standard deduction exists. Filing thresholds: income of $10,000 or less (single or separate) or $20,000 or less (joint, head of household, surviving spouse) owes no New Jersey tax at all, not merely a reduced amount.
The pre-tax rules nobody expects
New Jersey never adopted the federal treatment of cafeteria plans. Your 401(k) deferral reduces New Jersey wages — that one matches federal — but Section 125 health premiums and HSA contributions generally do not: they are taxed by New Jersey even as they escape federal tax. Compare boxes 1 and 16 on a New Jersey W-2 and the difference is usually exactly this. Enter your deductions above and the results keep the two ledgers separate, with a note showing what New Jersey declined to subtract.

What this page does not model
New Jersey paychecks also carry small employee contributions for unemployment, disability, and family leave insurance. Their 2026 rates were not confirmed against the Department of Labor at the time of review, and this site does not publish unverified figures — so those lines are absent here and the total is honest about it. They are typically well under one percent of wages combined. Property tax relief programs and the NJ earned income credit are filing-time matters.

Frequently asked questions
Why are my New Jersey wages on the W-2 higher than my federal wages?
Almost always the cafeteria plan. Federal law excludes Section 125 health premiums from box 1; New Jersey taxes them, so they stay in box 16. HSA contributions get the same treatment. It is not an employer error — it is the state's rule.
I earn under $20,000 filing jointly. Does New Jersey really take nothing?
Correct. At or below the filing threshold ($10,000 single or separate, $20,000 joint, head of household, or surviving spouse) there is no New Jersey income tax liability at all. Your employer may still withhold during the year; filing recovers it.
When does the 10.75% rate actually apply?
Only to taxable income above $1 million, on any filing status. The band below it, 8.97%, starts at $500,000. A $150,000 household never touches either — its top band is 6.37%, and its effective rate sits far lower once the wide low bands do their work.
I live in New Jersey and work in New York. Which state does this page cover?
The residence side. New York taxes the wages you earn there; New Jersey taxes you as a resident and then credits the New York tax, which for most commuters wipes out most of the New Jersey bill on those wages. Run the New York paycheck page for the work-state figure.
What are the UI, DI, and FLI lines on my actual pay stub?
Employee contributions to New Jersey's unemployment, temporary disability, and family leave insurance funds — small percentages on capped wage bases. Their 2026 rates were not verified at the time of this page's review, so this calculator leaves them out rather than guessing; expect the combined lines to trim a little more from each check.
