The State of New Jersey does not permit postmark. Taxes must be received in the Collector’s Office on or before the 10th. However, if the 10th falls on a weekend or Legal Holiday, you have until the next business day to make payment without interest.

Please notify Collector of Address change by phone, mail or fax. Tax bills are to be forwarded upon sale of a property between buyer and seller. Failure to receive a tax bill does not relieve the owner from paying taxes. Interest will be applied to all late payments. Please contact this office if you need a copy of your tax bill.
