Tax Bill Explanation:

Tax Bill Explanation

  • Calculated Quarters- On the upper left-hand corner of the tax bill, the amount listed under the property identification is the total taxes calculated for each quarter.
  • Block and Lot- On the upper left-hand corner of the tax bill, above the calculated quarters, is the block and lot number for the property associated with the tax bill. 
  • Net Taxes- On the upper right-hand section, underneath the tax percentage breakdown, is net taxes. This section will list tax deductions such as senior and veteran. (These credits may affect the overall tax amount owed.)
  • Total Anticipated Taxes- The bottom half of the tax bill is dedicated to information on the preliminary tax bill for the next year of taxes. The bottom right-hand section details the total billed tax amount due for Quarter 1 and Quarter 2 , 2023. 

*Please note the top portion of the tax bill is the calculation of the annual current year taxes and preliminary 2023 taxes. Please refer to the payment stubs for amounts due by quarter.

Tax Billing for Calendar Year Municipalities:

Please be advised that our estimated bills are mailed out prior to the certification of the final tax rate.

Our 2023 certified tax rate is $1.956 per one hundred dollars of assessed value. The calculation to determine the annual amount of taxes is as follows:

Annual taxes less first three quarters equal the reconciled fourth quarter. The fourth quarter tax bills will be mailed in the middle of September.

*First half billing (February and May) is half of the prior year tax as an estimate going forward each year. Millburn Township estimates a tax rate to bill the third quarter taxes as Essex County does not have their budget complete at this time.

All successful County Board Tax Appeals are processed as credits to the fourth quarter tax bill. The first half of 2024 will be revised as well based on the new lower value.

Any questions, please call the Tax Office at (973) 564-7084.
