The application required for incorporating as a Limited Liability Company (LLC) is called the Articles of Incorporation (also referred to as a Certificate of Incorporation). This document contains basic information about the company, its owners, and its directors. Depending on your state of incorporation, there may also be state-level fees or taxes that must be paid.
The articles of organization also should include information about how your LLC will be managed. You need to indicate whether the members of the LLC will do hands-on management or if there will be hired management. Another requirement is to discuss how long the LLC will be in existence (there is no limit on this, so it is fine to say in perpetuity).
