Introduction

The New Jersey Paycheck Calculator shows you how much money you actually take home from each paycheck. You enter your pay and a few details, and it calculates your paycheck.

Your gross pay is not what lands in your bank account. Taxes and deductions come out first. This tool subtracts federal income tax, Social Security, Medicare, New Jersey state income tax, and New Jersey payroll taxes like TDI, FLI, and SUI. It also handles pre-tax items such as health insurance and a 401(k), plus post-tax items like Roth 401(k) or union dues.

It works for salary or hourly jobs, any pay schedule, and overtime. You can also switch to an employer view to see the full cost of an employee, including FUTA, employer SUI, and workers' comp.

Every result comes with a clear breakdown, a chart, and a step-by-step solution so you can see exactly where each dollar goes. Use it to check a pay stub, plan a budget, or compare a job offer in New Jersey.

New Jersey Paycheck Basics

Your paycheck has two main numbers. Gross pay is what you earn before anything is taken out. Net pay (take-home pay) is what actually lands in your bank account. The gap between them is made up of taxes and deductions.

What Comes Out of a NJ Paycheck

  • Federal income tax: based on your Form W-4, your pay, and how often you get paid.
  • Social Security: 6.2% of wages, up to a yearly wage cap. Once you hit the cap, it stops for the rest of the year.
  • Medicare: 1.45% of all wages, plus an extra 0.9% on wages over $200,000.
  • NJ income tax: uses New Jersey's own brackets and its own allowance system from Form NJ-W4.
  • NJ TDI (state disability) and NJ FLI (family leave): small worker payments, each with a yearly wage cap.
  • NJ SUI / Workforce Development: a small unemployment payment from workers, also capped each year.

Two helpful facts: New Jersey has no local or city income tax, and workers' compensation is paid fully by the employer, so nothing comes out of your check for it.

Pre-Tax vs. Post-Tax Deductions

Pre-tax deductions come out first and lower your taxable wages, so you pay less tax. Health, dental, vision, FSA, and traditional 401(k) money are common ones. Note that 401(k) money still gets hit by Social Security and Medicare, and NJ still taxes HSA contributions even though the IRS does not.

Post-tax deductions come out after every tax is figured. Roth 401(k), union dues, and garnishments work this way. They do not cut your tax bill.

Why Pay Frequency Matters

Withholding math works by "annualizing" your check. Your pay is multiplied out to a full year, tax is figured on that yearly amount, then divided back down. That is why weekly, bi-weekly, semi-monthly, and monthly checks can show slightly different tax amounts even at the same yearly salary.

How to Change Your Take-Home Pay

The fastest lever is your W-4 and NJ-W4. Claiming dependents or adding deductions lowers withholding. Adding extra withholding raises it, which can help you avoid owing money in April. New Jersey also lets you pick a set withholding percentage on the NJ-W4 if your normal withholding comes out too low.

Year-to-Date Wages

Social Security, NJ TDI, NJ FLI, and NJ SUI all stop once your yearly wages pass their wage base. That is why your paycheck can suddenly grow later in the year. Entering your year-to-date gross wages gives a much more accurate result than starting from zero. Getting a bonus? Withholding on it works differently.

Results are estimates for planning. Your real paystub may differ based on employer settings, benefit rules, bonuses, and multiple jobs.

Frequently asked questions

Why is my calculated take-home pay different from my real pay stub?

Small gaps are normal. Common reasons include:

  • Your employer uses a wage-bracket table instead of the percentage method.
  • Your year-to-date wages are not exactly what you typed.
  • Benefit costs changed mid-year.
  • You had a bonus, commission, or unpaid time off.
  • Your employer rounds differently.

If the gap is large, check your W-4, NJ-W4, and deduction amounts against your stub.

Is New Jersey a high-tax state for paychecks?

NJ income tax starts low. The first $20,000 of taxable wages is taxed at just 1.5% for withholding. Rates climb as income grows, up to 11.8% at the top.

New Jersey also has no city or local income tax, which helps. But NJ does add small worker payments for TDI, FLI, and SUI that many states do not have.

What are NJ TDI, FLI, and SUI on my pay stub?

They are small New Jersey payroll taxes:

  • TDI: Temporary Disability Insurance. Pays you if you cannot work due to your own illness or injury.
  • FLI: Family Leave Insurance. Pays you when you bond with a new child or care for a sick family member.
  • SUI/WFD: Unemployment and Workforce Development. Helps fund jobless benefits and job training.

Each one stops for the year once your wages pass its wage cap.

Why did my paycheck get bigger later in the year?

You probably hit a wage cap. Once your yearly wages pass a cap, that tax stops for the rest of the year.

Social Security stops at the yearly wage base. NJ TDI, FLI, and SUI have their own, much lower caps. When SUI stops, that line disappears from your stub and your net pay goes up.

Can my NJ filing status be different from my federal filing status?

Yes. New Jersey uses Form NJ-W4, which is separate from your federal W-4. You can be Single on one and Married Filing Jointly on the other.

That is why this calculator asks for both. Enter what is actually on file with your employer for each form.

Does a traditional 401(k) lower my Social Security and Medicare tax?

No. A traditional 401(k) lowers your federal and NJ income tax only. Social Security and Medicare are still taken on that money.

Health, dental, vision, FSA, and commuter plans are different. Those usually skip income tax and FICA.

Do workers pay for workers' comp in New Jersey?

No. Workers' compensation insurance is paid 100% by the employer in New Jersey. Nothing comes out of your paycheck for it.

That is why the employee WCI rate shows 0%. The employer rate field only affects the Employer view.

What should I put for the employer NJ SUI rate?

New employers usually pay about 2.80%. Established employers get their own rate based on claims history, often between 0.50% and 5.80%.

Your exact rate comes from the New Jersey Department of Labor notice your company receives each year. Employees can ignore this field.

Should I check the W-4 Step 2 box?

Check it if you work more than one job, or if you are married filing jointly and your spouse also works.

It switches to the IRS higher-withholding schedule, so more tax comes out each check. That helps you avoid owing money at tax time, since a single job's withholding often assumes it is your only income.

How do I get less tax taken out of my paycheck?

A few options:

  • Enter your dependents credit in W-4 Step 3 if you have not.
  • Add extra deductions in Step 4b.
  • Add NJ-W4 allowances you qualify for.
  • Remove any extra withholding in Step 4c.

Only claim what you truly qualify for. Withholding too little means you owe money in April, plus possible penalties.

Why do weekly and monthly checks show slightly different tax?

Withholding annualizes your pay. Your check is multiplied out to a year, tax is figured, then split back into periods.

Rounding at each step causes tiny differences. Switch the results to Annual view and the totals will be nearly the same at the same salary.

What is the percent of net option for post-tax deductions?

It takes a percent of your pay after all taxes and other deductions are removed. Some garnishments and wage orders work this way.

The calculator figures your net first, then applies that percent. Use percent of gross instead if your deduction is based on total earnings.

Are these results good enough to plan a budget or compare a job offer?

Yes, for planning. The math follows IRS Pub. 15-T and NJ-WT withholding methods, so results are close to a real stub.

They are still estimates. Your actual pay depends on your employer's payroll settings, benefit costs, and other income. Use it as a strong guide, not an exact number.
