New Jersey Tax Calculator: Estimate Your Income Taxes in 2025

Understanding how much of your paycheck goes toward taxes in New Jersey can feel overwhelming. Whether you're a salaried employee, hourly worker, freelancer, or business owner, knowing what you’ll actually take home matters. That’s where a New Jersey tax calculator becomes essential.

In this guide, GTA Accounting Group explains how to use a NJ income tax calculator, what deductions apply, how much tax is taken out of your paycheck, and how to estimate your take-home pay in 2025. If you're looking for expert guidance or professional support, our accounting services in NJ are built to help.

Why Use a New Jersey Tax Calculator in 2025?

A NJ tax calculator helps you figure out how much income tax you’ll owe — whether you’re paid hourly, weekly, biweekly, or annually. With the 2025 tax year bringing possible changes in brackets and deductions, it’s more important than ever to use an updated New Jersey tax calculator.

Using a calculator gives you:

• Estimated net (take-home) pay
  
  
• Breakdown of federal, state, FICA (Social Security & Medicare) taxes
  
  
• Ability to adjust for 401(k) contributions, insurance deductions, and dependents
  
  

How Much Tax Is Deducted From a Paycheck in NJ?

Your NJ paycheck is subject to multiple tax withholdings:

1. Federal Income Tax – Based on IRS tax brackets and your W-4 settings
   
   
2. Social Security Tax – 6.2% of wages (up to the limit)
   
   
3. Medicare Tax – 1.45% of wages (plus 0.9% for high earners)
   
   
4. New Jersey State Income Tax – Ranges from 1.4% to 10.75%
   
   
5. Other Deductions – Includes health insurance, retirement contributions, and local taxes (if any)
   
   

Use a New Jersey paycheck calculator to simulate your paycheck and see exactly how much you'll take home.

Take-Home Pay Calculator NJ: How It Works

A NJ take-home pay calculator estimates your net income after taxes and deductions. Here's what it considers:

• Gross income (e.g., $100,000/year or $30/hour)
  
  
• Filing status (single, married, head of household)
  
  
• Number of dependents
  
  
• Pre-tax deductions (retirement, HSA, insurance)
  
  
• Post-tax deductions (wage garnishments, union dues)
  
  
• Federal + NJ state taxes
  
  
• FICA (Social Security and Medicare)
  
  

Example:
A single filer earning $80,000/year in NJ could expect around $58,000–$62,000 in annual take-home pay after taxes and deductions (estimate varies based on benefit deductions).
