New Jersey Paycheck Calculator — Current Tax Year
New Jersey paychecks carry more moving parts than almost any other state on this site. Beyond federal tax and a genuinely progressive state bracket system, New Jersey is one of the few states that also withholds employee-paid unemployment insurance, disability insurance, and family leave insurance straight from your check. This tool breaks out every single one of those lines so nothing is a mystery.

Why New Jersey Paychecks Have More Lines Than Most States
If you’ve ever compared a New Jersey pay stub to a friend’s from a neighboring state and felt like yours had more going on, you weren’t imagining it. New Jersey is one of the few states where employees, not just employers, contribute directly to the state’s unemployment insurance fund, disability insurance fund, and family leave insurance fund. Most states fund those programs entirely through employer-side payroll tax. New Jersey splits part of that cost onto the worker, which is why you’ll see SUI, SDI, and FLI as their own withholding lines, on top of the federal tax, state income tax, and FICA categories every paycheck has.
The Five Layers of a New Jersey Paycheck
- Federal income tax — based on IRS brackets, filing status, and dependents, identical to every other state.
- New Jersey state income tax — a genuinely progressive system running from a low 1.4% up to 10.75% for income above roughly $1 million, often nicknamed the “millionaire’s tax.”
- Social Security and Medicare (FICA) — the same federal payroll taxes withheld nationwide.
- State Unemployment Insurance (SUI) and Disability Insurance (SDI) — small employee-paid contributions, capped annually, that fund New Jersey’s unemployment and short-term disability programs.
- Family Leave Insurance (FLI) — a separate small employee contribution funding paid family leave benefits.
Individually, SUI, SDI, and FLI are usually modest dollar amounts. Together, though, they’re a genuinely distinct category that most generic paycheck calculators lump into a vague “other deductions” line or skip entirely — which is exactly the gap this tool is built to close.
| Deduction | Rate | Applies To |
|---|---|---|
| Federal Income Tax | 10%–37% | Taxable income after deductions |
| New Jersey State Tax | 1.4%–10.75% | NJ taxable income, progressive brackets |
| Social Security | 6.2% | Income up to the annual wage base |
| Medicare | 1.45% | All earned income, plus 0.9% for high earners |
| SUI + SDI + FLI | ~0.5% combined | Wages up to an annual wage cap, employee-paid |
A Detail Worth Knowing About the “Millionaire’s Tax”
New Jersey’s top 10.75% bracket gets a lot of attention, but it’s genuinely marginal — meaning it only applies to the slice of income above that threshold, not your entire paycheck. Someone earning $150,000 a year isn’t paying 10.75% on all of it; they’re paying New Jersey’s lower bracket rates on most of their income and only the top rate would apply to earnings above roughly $1 million, which is far beyond most salaries. This calculator applies the brackets correctly, layer by layer, the same way New Jersey’s own withholding tables do.
Frequently Asked Questions
What are SUI, SDI, and FLI on my New Jersey paycheck?
These are employee-paid contributions toward New Jersey’s unemployment insurance, short-term disability insurance, and family leave insurance programs. New Jersey is one of the few states that withholds these directly from employee wages rather than funding them entirely through employer taxes.
Is New Jersey’s income tax really progressive?
Yes. New Jersey uses a genuinely tiered bracket system where the rate increases as income rises, ranging from a low starting rate up to 10.75% for income above roughly $1 million.
Does the top tax rate apply to my entire salary?
No. Like federal tax brackets, New Jersey’s brackets are marginal, meaning only the portion of income that falls within a given bracket is taxed at that bracket’s rate.
How accurate is this calculator?
This tool applies New Jersey’s progressive state brackets, standard federal tax formulas, current FICA rates, and an estimated SUI/SDI/FLI contribution to closely match real withholding. Your employer’s exact payroll system may produce minor variations.
Do all New Jersey employees pay SUI, SDI, and FLI?
Most private-sector employees do, though contribution amounts are capped at an annual wage limit, meaning very high earners stop paying into these specific programs once their wages exceed that cap for the year.
How does a 401(k) contribution affect my New Jersey paycheck?
Pre-tax 401(k) contributions reduce your federal taxable income, though New Jersey notably does not allow the same pre-tax treatment for state income tax purposes on traditional 401(k) contributions, which is a quirk specific to New Jersey worth knowing.
Why is my New Jersey paycheck smaller than a similar salary in a no-tax state?
New Jersey combines a progressive state income tax with its unique employee-paid SUI/SDI/FLI contributions, resulting in more total withholding categories than states like Texas or Wyoming that have no state income tax at all.
How often are paychecks issued in New Jersey?
Pay frequency is set by the employer, though New Jersey law generally requires most employees be paid at least twice per month on a regular, predictable schedule.
