Why the rate here is not the whole story
Pennsylvania's state rate is 6 percent and Allegheny County levies a 1 percent local sales tax, for a combined 7 percent that applies at every address in the county. The county's authority comes from the Second Class County Code article that created the Allegheny Regional Asset District, which applies only to a county of the second class, and Allegheny is Pennsylvania's only second class county. No city, borough, township, school district or special district inside the county may add anything further, so 7 percent is both the floor and the ceiling. Act 21 of 2026 moved the local tax from point of sale to point of destination, so the 1 percent now follows where the customer takes delivery rather than where the vendor sits, and the Department is not enforcing that change until October 1, 2026. Most clothing and food that is not ready to eat are exempt from Pennsylvania sales tax, so a grocery or clothing receipt here often shows no tax at all.
