Per the PA Department of Revenue What taxes are imposed on a local level? webpage:
Local taxes are not administered by the PA Department of Revenue, but by local tax authorities in each area. For a list and brief description of local taxes which can possibly be levied by a municipality (i.e. borough, township, or city), school district, or county, please visit the Department of Community and Economic Development (DCED) website and click the Local Government link.
Another way to find out the specific taxes being levied in your municipality, school district, or county is to contact your local tax authority (check the government pages of your local telephone directory).
Note that any link in the information above is updated each year automatically and will take you to the most recent version of the webpage or document at the time it is accessed.
