A Limited Liability Company (LLC) is the simplest form of company in the United States.
While most businesses are companies (or corporations), not all companies are businesses. LLC’s are commonly used for non-business purposes, such as holding an asset, such a piece of real estate - or a vehicle.
Unlike corporations, LLC’s do not need to elect a board of directors, adopt bylaws, hold annual meetings, or create formal financial statements.
Companies are formed at the state level, not the national level. So, there is no such thing as a US LLC. Instead, there are Delaware LLC’s, New York LLC’s, California LLC’s, etc.
