Which of the following is NOT a requirement when forming a corporation?

When forming a corporation, stating the business purpose is generally a requirement, but it does not need to be expressed with high specificity. Most jurisdictions allow for a broad statement of the business purpose in the articles of incorporation. For instance, a general phrase like "to engage in lawful business activities" is often sufficient. This flexibility is intended to permit corporations to adapt their activities without needing to amend their formation documents frequently.

In contrast, the other elements listed are more strictly regulated. The incorporation name indeed requires specific words or abbreviations, such as "Corporation," "Incorporated," or their abbreviations, to clarify the entity's status. Filing articles of incorporation with the state is also vital for creating the corporation legally, as this document officially establishes the existence of the corporation. Lastly, including the registered agent and its address is crucial since it provides a point of contact for legal documents and correspondence. Overall, while outlining a business purpose is important, the level of specificity required is not as stringent as the other requirements.
