Understanding NJ Income Tax (Helpful Info)

  • NJ is a progressive tax state: The more you earn, the higher your marginal tax rate.

  • Dependents matter: Each dependent can reduce your taxable income, potentially saving hundreds in taxes.
  • Tax brackets differ: New Jersey’s rates are lower for low-income earners but rise steeply at higher incomes.
  • You may also owe federal tax: This tool estimates NJ state taxes only.
