Deadline and where to file
Wilmerding values are set by the local county assessment office. Under state law the annual appeal deadline is September 1, unless the county commissioners choose an earlier date no sooner than August 1 (many counties use August 1). If your assessment changes mid-year, you have 40 days from the date of the notice. Philadelphia is different: the Board of Revision of Taxes deadline is the first Monday in October of the year before the tax year.
Reading this in fall 2026? If you live in Philadelphia, the deadline for 2027 values is Monday, October 5, 2026, which is the day after today, so file immediately with the Board of Revision of Taxes. Everywhere else in Pennsylvania the 2026 annual deadline (August 1 or September 1) has passed. Your next regular chance is August 1 or September 1, 2027 (check your county's date), unless you get a change-of-assessment notice, which gives you 40 days to appeal.
The Allegheny County guide covers the full Pennsylvania appeal process: forms, fees, hearing levels and what happens next.
