Why the rate here is not the whole story
Pennsylvania's state sales tax is 6 percent and that is the rate at every address in Westmoreland County, because nothing below the state may be added here. Pennsylvania authorises exactly two local sales taxes: 1 percent in Allegheny County under the Second Class County Code article that created the Allegheny Regional Asset District, which defines county as a county of the second class and so reaches Allegheny alone, and 2 percent in Philadelphia under the Pennsylvania Intergovernmental Cooperation Authority Act for Cities of the First Class. No statute lets any other county, city, borough, township, school district or special district levy a sales tax, and the Local Tax Enabling Act separately bars local governments from taxing a subject already subject to a state tax, so there is no local rate to look up in this county. Most clothing and food that is not ready to eat are exempt from Pennsylvania sales tax, which is unusual, so many grocery and clothing receipts here show no tax at all. County hotel room rental taxes are a different tax and are not part of this rate.
