Allegheny County Court Orders Reassessment of 585,000 Properties Using Values Frozen Since 2012
A Common Pleas judge signed an order on August 17, 2026, requiring Allegheny County to replace its 2012 base-year property values through a countywide reassessment starting by July 2027 and completed before June 30, 2032. Pennsylvania law requires taxing districts to set revenue-neutral millage rates in the first year after a reassessment, but individual tax bills can still rise or fall depending on how each property's share of the total revised assessment roll changes. The article explains the court order's timeline, the millage adjustment process under state law, and the existing appeal mechanism available to property owners.
