Returned or insufficient payment
If a property-tax or sewer payment is returned for insufficient funds, Hamilton Township says the replacement must be made with certified funds after the Tax Collector receives the bank notice. The Township FAQ also lists a separate $20 returned-check fee.
Tax sale
Hamilton Township states that unpaid municipal tax, sewer or assessment charges can become subject to tax sale under New Jersey law. Accounts approaching or already involved in tax-sale proceedings should be handled directly with the Tax Collector because acceptable payment methods and payoff requirements can differ from a normal current-quarter bill.
