How does New Jersey state income tax and unemployment insurance work in 2026?

The single-filer bands start at 1.40% on the first $20,000, then 1.75% to $35,000, 3.50% to $40,000, 5.53% to $75,000, and 6.37% to $500,000. Above that, the rate steps to 8.97% and then the 10.75% millionaire rate above $1,000,001, one of the highest of any US state. Compare that bracket structure with New York state tax and UI or Pennsylvania's flat-tax approach if you hire across the tri-state area.

You remit withholding to the New Jersey Division of Taxation. The trap for first-time New Jersey employer of record arrangements is treating withholding as the whole job. It's the simplest part. The cost and the deadline risk sit in the unemployment, disability, and family-leave programmes that withholding does not touch.

The NJ-W4 matters because an employee can claim a different withholding rate table for state than for federal, and you must keep the form on file. Get the registration wrong and you face late-deposit penalties from the Division of Taxation on top of the federal IRS ones. Employer withholding deposits are weekly, monthly, or quarterly depending on payroll size, so a larger New Jersey team files far more often than a small one. Check the US hiring overview for the federal deposit calendar that runs underneath every state obligation.

New-hire reporting is a separate obligation. You report each new employee to the New Jersey New Hire Reporting Center within 20 days. Miss it and penalties stack per employee. The federal layer runs underneath all of this: Social Security and Medicare under FICA, plus federal unemployment tax, on every New Jersey paycheque.

This is the New Jersey hook: a single hire generates contributions across several funds, some employer-paid, some employee-deducted, on two different wage bases. You pay UI on the first $44,800 of wages, plus an employer disability contribution on that same base. The employee TDI and FLI deductions run on a much higher $171,100 base, so a senior salary keeps contributing well past the UI ceiling. Family Leave Insurance is funded entirely by the employee, which is unusual among US states. Compare how that stacks against Connecticut's UI and leave contributions if you hire across the border.

The employee rates reset every year, which catches payroll teams off-guard. For 2026, employee TDI is 0.19% and FLI is 0.23%, both lower than 2025. Employee UI and disability withholding tops out near $190.40 for the year, with TDI up to $325.09 and FLI up to $393.53. The NJ Division of Temporary Disability and Family Leave Insurance publishes updated caps each autumn.

Earned Sick Leave applies to nearly every New Jersey employer with no employee-count floor. Workers accrue one hour for every 30 hours worked, up to 40 hours a year, and carry forward up to 40 hours. A single New Jersey hire triggers it, so this is not a big-employer rule. Full details are in the paid family and sick leave guide.

The New Jersey Family Leave Act gives up to 12 weeks of job-protected leave in a 24-month period to bond with a child or care for a family member. Its coverage threshold is dropping to far smaller employers in 2026, so the old assumption that only large employers must comply no longer holds. The federal FMLA sits alongside this for employers with 50 or more staff. The $15.92 minimum wage rises most years under a scheduled step-up plus an inflation adjustment, and lower rates apply to seasonal, small, and agricultural employers. Check New Jersey wage and overtime law for worker-category details and the termination clock in New Jersey termination law and at-will exceptions.

Real HR and legal experts handle your New Jersey hires. They know the seven-bracket withholding table, the $44,800 UI base, and the 0.19% TDI and 0.23% FLI employee rates. An actual person, not a chatbot or a pooled queue. You see every cost: state income tax withheld, UI and disability contributions, the employee TDI and FLI deductions, and federal employer taxes pass through at cost, itemised and auditable on every invoice. No setup fee, no exit fee.

Contractor onboarding, EOR payroll, and entity graduation all live on one platform: a New Jersey contractor who converts to W-2 keeps their record, and that same employee can graduate to your own US entity without switching systems. Because New Jersey makes you juggle several separate funds at once, on two wage bases, the administrative load per head is higher than in a no-tax state. That changes the point at which your own entity pays off. Use the Crossover Calculator to find the month the model flips, or the Employer Cost Calculator to price out the full New Jersey payroll bill before you hire. When the model no longer fits, Teamed transitions you cleanly, with no exit fee. Talk to an expert to work through the numbers.
