An LLC that does not want to accept its default federal tax classification, or that wishes to change its classification, uses Form 8832, Entity Classification Election (PDF), to elect how it will be classified for federal tax purposes. Generally, an election specifying an LLC’s classification cannot take effect more than 75 days prior to the date the election is filed, nor can it take effect later than 12 months after the date the election is filed. An LLC may be eligible for late election relief in certain circumstances. See About Form 8832, Entity Classification Election for more information.
Decide if your LLC will be member-managed or manager-managed. A "member" of an LLC is either an owner of or investor in that LLC. A member-managed LLC affords each member equal rights in deciding how the business will be run. A manager-managed LLC is where the members elect several from their number to be responsible for the company's business affairs.
