If the Board Assessment Review grants you a reduction, expect to see your new lower assessment on your December tax bill.

If your Property Tax Grievance is denied, and we believe we can still win you a reduction, we will file an appeal on your behalf. The Critical Dates for the Appeal Process are:

Appeal Deadline  Within 30 days of Grievance Denial
Hearings Call Office for Details
Final Decisions Within 30 days of the Hearing Date

If your case goes to Appeal and we successfully win a reduction for you after the beginning of the tax year:

  • Your 2nd half tax bill will be revised to reflect your new assessment, AND
    credit you with the overpayment you made on the 1st half bill


  • A refund check will be issued if your taxes are paid in full.
