Pennsylvania has no single statewide property tax appeal deadline. Each of the state's counties sets its own annual deadline.
A typical appeal centers on comparable sales data and documentation showing the assessed value does not match market value.
Property owners who receive a Change of Assessment Notice (for example after new construction or an addition) generally get a separate, shorter filing window tied to that notice date, distinct from the standard annual deadline. The exact number of days varies by county.
