The Tax Collector is responsible for the billing, collection, reporting, and enforcement of municipal taxes for the Township of South Brunswick. Property taxes are due on February 1, May 1, August 1, and November 1. Failure to receive a tax bill does not exempt you from paying taxes or the interest due on delinquent taxes.
There is a 10 day grace period; taxes must be received in the tax office on or before the 10th. If the 10th falls on a weekend or legal holiday, you have until the next business day to make a payment. Payments received after the 10th will have interest charged back to the due date. Postmarks are not accepted.
If you recently purchased a property in South Brunswick and do not have a tax bill, please contact our office for the amount due, or click the button below to access your account.
