Expert Tax Services for New Jersey Businesses & Individuals

Understanding the New Jersey Tax Landscape

New Jersey consistently ranks among the highest-tax states in the nation. With a top marginal Gross Income Tax rate of 10.75% — one of the highest state income tax rates in the country — and property taxes that average over $9,000 per year statewide, the stakes for proper tax planning are enormous for NJ residents and business owners.

The federal cap on state and local tax (SALT) deductions has had an outsized impact on New Jersey taxpayers. The 2017 Tax Cuts and Jobs Act set the cap at $10,000. For 2026 it is $40,400, phased back down toward $10,000 for very high earners. New Jersey responded by enacting the Business Alternative Income Tax (BAIT) — a mechanism that allows pass-through entity owners to effectively exceed the SALT cap — and understanding how to leverage this election is one of the most valuable things a NJ business owner can do.

Beyond income taxes, New Jersey businesses must also navigate sales tax obligations, payroll taxes, unemployment insurance taxes, and — if they have employees in or customers from other states — an increasingly complex multi-state compliance landscape. The post-Wayfair economic nexus rules have created new sales tax obligations for many NJ-based e-commerce sellers and service businesses that previously had no out-of-state tax presence.

ProAxis specializes in helping NJ businesses and individuals understand this landscape clearly, make smart decisions, and stay compliant — without overpaying.
