  1. If a mortgage company is to pay your bill, it is your responsibility to call them and ask if you need to send them a copy of your bill. Many mortgage companies now pay electronically and may not require a bill.

  2. If you no longer own this property, it is your responsibility to mail the bill to the new owner.

  3. Installments equal to one-half the total tax are due on or before the due dates shown on the front of the tax bill, or the entire bill may be paid by the first installment due date. 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 delinquent tax list will be published after the second due date. Additional costs and interest will be added at tax sale or forfeiture. A minimum charge of $30.00 will be added for checks returned to us by a bank and the tax payment will be voided.

  4. 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.
