Andover Borough Tax Collector, Attention: Melissa Caton, 137 Main Street, Andover, NJ 07821
Please be advised that the State of New Jersey does not allow the Tax Collector to acknowledge postmarks, therefore, taxes must be received in the 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. Payments received after the grace period will be assessed 8% interest per annum on the first $1500.00 of delinquency and 18% per annum on all balances over $1500.00. Any balances over $10,000.00 at December 31 will be assessed an additional flat 6% penalty.

- Taxes are due February 1, May 1, August 1 and November 1.
- If you pay your taxes through your mortgage company, the statement will say "This is not a bill, for advice only". If you receive an "advise only" statement, but do not have a mortgage company, please use this statement to pay your taxes
- When selling your property, this bill must be handed over to the new owner at the time of closing
