The county equalization board normally meets in the months of August and September to hear assessment appeals. Schedule your appointment for appeal with the county clerk prior to this meeting. The last day to appeal to the board is August 20th.
Call your county assessors' office first for an informal appeal. If you are not satisfied with the results then call your county clerk and schedule an appointment with the county equalization board. It is too late to appeal after you have received your tax bill but the assessments for the next tax bill may be appealed.
Taxes may be paid by mail or in person to your local county collector and are due by the 15th day of October. Real estate taxes may be paid in installments: 1/4 due by April 15, 1/4 due by July 15, and the final 1/2 due by October 15.
