Allows certain municipalities to establish lower property tax rate on improvements than land.

This bill allows certain New Jersey municipalities - specifically those in urban enterprise zones (current or former) - to adopt a "land-based property tax system" where improvements (like buildings) are taxed at a lower rate than the land they sit on. Other municipalities may apply for approval to implement this system after seven years, but must meet standards preventing its use in areas primarily dedicated to open space, farmland, or environmental preservation. The system permits gradual phase-in of tax rate differences and allows municipalities to revert to a single tax rate if desired. The goal is to encourage redevelopment of vacant urban land by making property improvements more financially attractive to owners, potentially increasing housing and economic activity in targeted areas.
