Pennsylvania’s highest court has awarded a more than two-million-dollar tax refund to a Pennsylvania-based arm of Johnson & Johnson. Reached last week, the decision hinged on whether the company owed taxes in Pennsylvania based on services produced in the state but sold to customers in other states. The answer was clarified in 2014 under a change to Pennsylvania’s corporate tax code, but court watchers say that answer had become murky due to different interpretations of the code.
