Tax Collector

The Tax Collector is responsible for the billing and collection of municipal taxes. Warren Township is a calendar year town so bills are mailed annually in July. The bills will have the current 3rd and 4th quarter.

Tax Amounts

Tax amounts are determined by the newest assessment (set in January) and the current tax rate (set in July). The following year’s first half is half of the prior year’s total. Added Assessment bills are sent in October and are due in November for new homes or improvements. They will carry over to the following year 1st and 2nd quarter and should be combined with your original bill. The amounts will be combined on the next annual bill.


The Warren Township Committee would like to advise sewer customers that the 2023 billing cycle will be changing this year.  The bills will not be mailed out in January, as has been the practice, and they will not be due on February 1, 2023.     

As a result of the dissolution of the Warren Township Sewerage Authority in July 2022, the Township now manages the sewer function.  

According to New Jersey finance laws, the Sewer Utility Budget follows the same schedule as the Township Budget, not the schedule of an Authority Budget. 

As a result, the following will be proposed for 2023:

  • The sewer rates will be approved March 2023
  • The sewer bills will be mailed by April 10, 2023
  • The first half will be due on May 1, 2023
  • The second half will be due on November 1, 2023
  • There will be a ten-day grace period for both.

The Township apologizes for any inconvenience this may cause you and appreciates your cooperation.
