After you've completed the steps described above, your LLC is official. But before you open your doors for business, you need to obtain the licenses and permits that all new businesses must have to operate. These may include a business license (sometimes also referred to as a "tax registration certificate"), a federal employer identification number, a sellers' permit, or a zoning permit. For more on business licenses and permits, see the Licenses & Permits for Your Business area of Nolo's website.
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.
