          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.



2019 final/2020 preliminary tax bills have been mailed out.  The 4th quarter tax bill is due November 1st, 2019.  If you received an added/omitted bill, please note this bill is due in addition to your regular tax bill for the next three quarters. 


There is a 10 day grace period counting the 1st.  If the 10th falls on a weekend or a holiday, the due date is exteded until the next business day.
