Does Pennsylvania law require corporations to have more than one officer?

Yes and No. The law requires three offices for every corporation, but the same person may hold all three offices. Pennsylvania requires corporations to have a president, a secretary, and a treasurer. The offices of president and secretary must be natural persons at least 18 years old; however, the office of treasurer may be held by another corporation or a natural person at least 18 years old. Pennsylvania law explicitly allows the same person to hold any number of offices of a corporation.
