Welcome to FAQs for your taxes. If you don't find your question answered below please visit the tax collector's page,  or contact our tax collector, Sharon Brown at




1) How is the amount of my property tax determined?

In order for the amount of your tax to be determined, the Office of the Assessor must first assess the value of your property. After the Office of the Assessor has determined the property value, the Office of the Collector applies the appropriate tax rate which includes the following:

            County Rate

            County Library Rate

            County Open Space Rate

            Municipal Rate

            Municipal Open Space Rate

            Local & District Schools Rate


The Office of the Collector prepares the tax bills based on the calculations, distributes the bills, and then collects the taxes.


For more information on how the assessed value is determined, contact the Office of the Assessor at (908) 806-6933

2) Do I have recourse if I disagree with the assessor

Yes, if you disagree with the assessed value of your property you may contact the Office of the Assessor at (908) 806-6933. They can provide you with information on how the value was established.


If you choose to appeal your assessment, you must still pay your property tax in full by the appropriate deadlines, otherwise you will incur penalties while the case is on appeal. If your appeal is granted, an adjustment / credit will be given based on the new assessed value.

3) I have recently purchased property. What are my responsibilities as far as taxes are concerned?

You are responsible for any taxes which were not paid as the time of closing. Even though taxes are prorated between the buyer and seller and proper credit is given to each, the actual taxes may not have been paid to the Office of the Collector. You should read your escrow papers and/or title report to determine if any portion of the annual taxes were paid by the previous owner.


The property tax bill is an annual bill and is mailed once a year in mid-summer. The property tax bill contains 4 payment subs for 4 installments, the 3rd and 4th Qtrs of one year and the 1st and 2nd Qtrs of the next year. Depending on when the ownership change is place on the tax roll, the annual tax bill is sent either to the previous owner or directly to you. If you have not been given the bill, contact the Office of the Collector to obtain a bill for any remaining quarters.


Installments are due on the following dates with a 10 day grace period.


                      February 1, May 1, August 1 & November 1


It is your responsibility to obtain your annual tax bill. Failure to receive a bill does not provide a basis for excusing penalties for late payment.
