Tax Collection/Water/Sewer

From the Township Finance Department:

The Montclair tax and utilities payment office sees dozens of property owners come in every day to pay their bills.

  • CHECK PAYMENTS may be dropped off into the box located outside, at the front of the building, next to the US Postal Service mailbox.
  • All checks must be in an envelope clearly noting to which department they should go, or what services are being paid for (Clerk's office applications, building department, water/sewer bill, etc.)
  • If you need confirmation of receipt of payment, please call the appropriate department for confirmation but please wait two weeks for processing payment.

Tax Payment Due Dates and Grace Periods

Tax payments are due four times a year: February 1, May 1, August 1, and November 1. Tax payments have a 10-day grace period -- on the 11th day of each quarter tax payments are subject to interest.

The interest on late payments for taxes is calculated at a rate of 8% on the first $1500.00 and 18% for any amount over $1500.00, retroactive to the first of the month.

If you have any questions about tax payments, please call the Tax Department at 973-509-4923, 4922, 4921.
