What document must be filed to form a domestic corporation in Pennsylvania?

To establish a domestic corporation in Pennsylvania, the required document is the Articles of Incorporation. This document is crucial as it formally lays out the foundation for the corporation, including essential details such as the corporation's name, its purpose, the principal office address, and the number of shares it is authorized to issue. The Articles of Incorporation must be filed with the Pennsylvania Department of State to legally create the corporation.

The other options are relevant to different business structures. The Certificate of Organization is used for limited liability companies (LLCs), while the Certificate of Limited Partnership pertains to forming limited partnerships. Bylaws, while important for providing internal governance for a corporation, do not need to be filed with the state; instead, they are adopted by the corporation after formation and are typically kept as internal documents. Hence, the Articles of Incorporation is the specific requirement for forming a domestic corporation in Pennsylvania.
