These are some of the Pennsylvania and federal rules a small business with a website runs into:
- Municipal requirements are separate: check with the local municipality about taxes, zoning requirements, local licenses and permits. In Sewickley Heights, that means asking Allegheny County and the Borough of Sewickley Heights. Official source
- Accessibility is a federal matter: the Justice Department’s ADA guidance covers the websites of businesses open to the public. ADA.gov guidance
- The Pennsylvania sales tax rate is 6 percent. Only two local add-ons exist: 1 percent in Allegheny County and 2 percent in Philadelphia. Pennsylvania Department of Revenue
