The school board levied a real estate tax of 21.9340 mills in 2014–15. A mill is $1 of tax for every $1,000 of a property's assessed value. Property taxes, in the Commonwealth of Pennsylvania, apply only to real estate - land and buildings. The property tax is not levied on cars, business inventory, or other personal property. Certain types of property are exempt from property taxes, including: places of worship, places of burial, private social clubs, charitable and educational institutions and government property. Additionally, service related, disabled US military veterans may seek an exemption from paying property taxes. On the local level, Pennsylvania district revenues are dominated by two main sources: 1) Property tax collections, which account for the vast majority (between 75 and 85%) of local revenues; and 2) Act 511 tax collections, which are around 15% of revenues for school districts. 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.
