How are property taxes calculated?
Property taxes are calculated by multiplying the assessed value of your property by the current year tax rate.  The Tax Assessor determines the assessed value of your property, while the Morris County Tax Board determines the annual tax rate based on school, municipal and county adopted budgets.

When do I receive my tax bill?
Tax bills are mailed annually in July, and include the third and fourth quarters of the current tax year and the first and second quarters of the upcoming tax year. Residents whose mortgage companies escrow property taxes on their behalf will be sent an ‘Advice Only’ copy of the tax bills that will not contain the payment stubs.  If you misplaced your tax bill or are a new home owner, contact the Tax Office during normal business hours for a duplicate copy.

When are taxes due?
Property taxes are due February 1st, May 1st, August 1st and November 1st. There is a 10 day grace period. Tax payments received after the grace period will accrue interest back to the first. The interest rate for delinquent taxes by state statute is as follows: The first $1500 of delinquency is at 8% (APR) any balance over $1500 is at 18%. The 18% interest remains until the delinquency is brought current. A 6% year-end penalty will be assessed on the last day of the fiscal year on delinquent accounts in excess of $10,000. Per N.J.S.A. 54:4-64(3) the validity of any tax or assessment, or the time at which it shall be payable, shall not be affected by the failure of a taxpayer to receive a tax bill.

What property tax deductions are available?
Eligible Veterans, Senior Citizens (individuals 65 years of age or older), and Disabled individuals may receive a $250 property tax deduction.  Individuals who believe they qualify for a deduction can obtain an application from the Tax Office during normal business hours.  Please be sure to read the back of the application for the necessary documentation that must accompany your completed application.

What is an Added Assessment bill?
Added Assessment tax bills are for new construction or improvements to an existing structure that are sent out once a year in October, and are to be paid November 1, in addition to your regular tax bill.  Mortgage companies do not always include this payment in with your regular tax payment to the township, therefore, it is ultimately the homeowner’s responsibility to be sure that the added assessment taxes are paid in a timely manner.
