For 2018-19 school year, the Milton Area School Board raised the local property tax to 67.86 mills for residents in Northumberland County. District residents in Union County were taxed at 16.40 mills. 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 all government property (local, state and federal). 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 75-85%) 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.
