Advance Tax

Print


Advance tax is available November through December. The advance tax program allows you to prepay your property taxes for the next tax year.

In order to participate in advance tax you need to:

  • Fill out and sign The Advance tax agreement and returned it to our office with your check.
  • Pay any outstanding balance by the first installment due date.
  • To correctly identify the property we ask that the Permanent Index Number of all the parcels being paid appear on the form, or a copy of the tax bill must accompany the payment.
  • If you have any questions, please call our office at 815-334-4260.
