Tax Billing & Payments
Real Estate Property Taxes
The billing and collection of real estate property taxes is governed by state law and applies to every municipality in the State of New Jersey. Your tax bill includes revenues collected by the Township on behalf of the municipality, county and school district. Your tax bill is based on the assessed value of your property, and you pay taxes for every $100.00 of assessed value.
