Installments unpaid by the due date will have interest added at the rate of 1.5% per month until they are paid. Property owners who have delinquent taxes remaining after the second due date will be mailed a delinquent bill and a $10.00 fee will be added to the amount due.

A minimum charge of $30.00 will be added for checks returned to us by a bank and the tax payment will be voided.

  8. Failure to receive a tax bill, or receiving one late, for any reason, will not relieve the taxpayer from paying taxes or late penalties. Payments made on a wrong parcel cannot be refunded.
