Key Property Tax Appeal Dates

October - December 2019

Effective property tax appeal representation and pre-acquisition due diligence analyses have never been more critical for owners and prospective buyers of commercial and industrial real estate. Many property owners have experienced dramatic increases in their property tax liability in the past few years and have found themselves at a competitive disadvantage relative to similar properties.

Upcoming appeal deadlines that are quickly approaching are detailed below. In most cases, protests must be filed 30 days after the jurisdiction issues the notice of proposed assessment, or the values become final, and appeal rights are lost.


Appeal Deadline: December 2

Notes: An appeal must be filed between 7/2 and either 9/16 or 12/02 (depending on County). With the exception of Supplemental and Escape, the deadline to file is 60 days from the date of the notice.
