  • When paying by check, money order or cashier's check, please make sure the amount is exact or we will be unable to accept the payment.
  • Neither failure to receive a tax statement, nor receiving one late will relieve the taxpayer from paying the taxes or any penalties which may become due.
  • Installments equal to at least one-fourth the total tax are due on or before the due dates shown on the front of this statement, or the full tax may be paid by the first installment due date.
  • State law requires the installments not paid by the due dates shall have interest added at the rate of 1.5% per month or part of a month until paid, sold, or forfeited.
  • No second notice will be mailed covering your second, third, and/or fourth installment, as all four stubs are included with your original tax bill.
  • Payments in-person are also accepted mobile home taxes.
