What New Jersey tax professionals need to know

Several key considerations make New Jersey's tax landscape complex for 2025:

New Jersey's progressive tax system, with rates from 1.4% to 10.75% creates significant tax planning opportunities. The state offers various deductions and credits that can substantially reduce tax liability for qualifying taxpayers.

Tax System Modernization & Online Filing Downtime

  • Existing tax system: Temporarily unavailable for filing April 26, 2025, through May 13, 2025.
  • New NJ Tax Portal: Becomes operational May 14, 2025. Businesses/filers set up accounts at that time.
  • Automatic 30-day extension for all returns and payments due May 1 – May 30, 2025, for Phase 1 taxes (including sales and use tax); no penalty or interest applied for these periods. For example, a May 20 due date gets moved to June 20.

Real Property Transfer Fee Increases (Mansion Tax)

  • Effective July 10, 2025, property transfer taxes and fees increase for sales over $2,000,000, with graduated rate brackets as described:
    • $1M–$2M: 1.0% (unchanged)
    • Over $2M–$2.5M: 2%
    • Over $2.5M–$3M: 2.5%
    • Over $3M–$3.5M: 3%
    • Over $3.5M: 3.5%
    • These apply to both the “mansion tax” (Supplemental Realty Transfer Fee) and Controlling Interest Transfer Tax (CITT).

Agricultural Provisions, Inheritance Tax, and Other Unique Features

  • Farmers: If at least two-thirds of your gross income is from farming, you may pay all estimated tax by January 15, 2026, or file your returns by March 1, 2026, with full payment, allowing you to skip estimates.
  • Inheritance tax remains: No estate tax has been in effect since January 1, 2018; however, inheritance tax may still apply based on the beneficiary.
  • No local sales tax: The state sales tax is 6.625%, with no additional local charges.

High-income taxpayer considerations

New Jersey's high tax rates create special considerations:

  • The top marginal rate of 10.75% the highest in the nation
  • Millionaire's tax provisions for very high earners
  • SALT deduction limitations may affect high-income taxpayers

New Jersey tax planning opportunities

Available deductions and credits

New Jersey offers various tax benefits:

  • Property tax deduction for homeowners
  • Earned Income Tax Credit for qualifying low-income taxpayers
  • Pension and retirement income exclusions for seniors
  • Child and dependent care credit

Residency planning

Given New Jersey's high tax rates, residency planning becomes crucial:
