The school board set property tax rates in 2015–16 at 110.75 mills. A mill is $1 of tax for every $1,000 of a property's assessed value. Irregular property reassessments have become a serious issue in the commonwealth as it creates a significant disparity in taxation within a community and across a region. Pennsylvania school district local revenues are dominated by two main sources: 1) Property tax collections, which account for the vast majority (between 75–85%) of local revenues; and 2) Act 511 tax collections (Local Tax Enabling Act), which are around 15% of revenues for school districts.
