Pennsylvania Annual Tax Assessment Appeal is a process for property owners to contest their property assessment. Property owners can appeal their assessments to the county Board of Assessment Appeals or to the Pennsylvania Board of Tax Appeals if the county board denies their appeal. Property owners can file an appeal to contest their property's value, classification, or exemption status, and may include evidence such as comparable sales data, photos, or other documents to support their case. There are two types of Pennsylvania Annual Tax Assessment Appeals: Class Appeal and Unilateral Appeal. Class Appeal is an appeal on behalf of a group of properties that have similar characteristics and are similarly assessed. Unilateral Appeal is an appeal filed by an individual property owner who believes that their assessment is not fair or correct.
