Tax information available on the Allegheny County Assessment Website includes property tax calculation, school district tax mileage rates, municipality tax mileage rates and a list of county tax collectors. The site has a step-by-step process for taxpayers to follow when looking up their property tax assessments.
Allegheny tax officials use mileage rates to calculate property tax by multiplying an assessment by the mileage for the municipality, school district and Allegheny County. The definition of mileage is the amount per $1,000 used to calculate the assessment. For example, Allegheny County has a mileage rate of 5.69, while Allepo Township has a rate of 5.00, and the Quaker Valley School district has a rate of 4.69.
