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 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 & 2nd quarter and should be combined with your original bill. The amounts will be combined on the next annual bill.

Payment can be made in the office at 46 MOUNTAIN BLVD. or sent to our lockbox at

PO BOX 1364

Warren Township is a calendar year town so BILLS ARE MAILED ANNUALLY IN JULY. Bills will have the current 3rd and 4th quarters as well as the following year’s 1st and 2nd quarters.

Property taxes are due February 1, May 1, August 1, and November 1. There is a 10 day Grace Period for each quarter.

Please submit any requests for an address change to the collector’s office in writing. We need the block and lot, property location, the new address, and the signature of the homeowner. Forms are also available in the Tax Office. Please mail the request to 46 Mountain Blvd, Warrant, NJ 07059 or fax it to 908-753-7768.

PAYMENTS MUST BE RECEIVED IN THE OFFICE ON OR BEFORE THE 10TH. When the 10th falls on a weekend or legal holiday, you will have until the next business day to pay. After the 10th, interest is charged back to the 1st. The state of New Jersey does not allow the tax collector to acknowledge postmarks. The grace period may be extended by resolution in certain circumstances.

ADDED ASSESSMENTS BILLS ARE SENT IN OCTOBER and due in November for new homes or improvements. They will carry over to the following year’s 1st & 2nd quarter and should be combined with your original bill.

Interest is calculated at 8% on delinquencies up to $1,500.00 and at 18% on the amount over $1,500.00. Once the balance is over the 18% threshold, interest will be 18% until all balances are paid in full.

There is a 6% year end penalty on taxes & accrued interest over $10,000.00 that are delinquent as of December 31st

If you misplace your bill or did not receive the bill, please call the office and we can send a duplicate copy or a printout. As per New Jersey state statute, failure to receive a tax bill does not affect the due date or the date that interest begins to accrue. It is the responsibility of each tax payer to obtain the amount due on their property.

If you have paid off you mortgage or change mortgage companies you should notify the tax office in writing. You can also get a form in the tax office. You will receive a bill marked “THIS IS NOT A BILL FOR ADVICE ONLY” at the time bills are sent out. This is exactly like the bill sent to the mortgage company and can be used once you know the MORTGAGE COMPANY is no longer paying.

If you have a new MORTAGAGE COMPANY please contact them to be sure you know when they will begin making tax payments.

There are two property relief programs available to New Jersey homeowners and there are veteran and senior citizen deductions available. The veteran’s and senior citizen deductions are both $250.00 and will come off your tax bill. There are income restrictions for senior citizens ($10,000 NOT INCLUDING SOCIAL SECURITY) and others for veterans. You can contact the assessor’s office (EXT. 235) for forms and more information.
