Property tax rates in 2014-15 were set by the West Branch Area School Board at: 97.00 mills for district residents in Clearfield County and 10.90 mills for district residents in Clinton County. 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. Clinton County conducted a reassessment in 2008. 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. Pennsylvania school 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. The school district includes municipalities in two counties, each of which has different rates of property tax assessment, necessitating a state board equalization of the tax rates between the counties. In 2010, miscalculations by the board were widespread in the Commonwealth and adversely impacted funding for many school districts.
