A Limited Liability Company (LLC) is a business structure allowed by state statute. Each state may use different regulations, and you should check with your state if you are interested in starting a Limited Liability Company.
Owners of an LLC are called members. Most states do not restrict ownership, and so members may include individuals, corporations, other LLCs and foreign entities. There is no maximum number of members. Most states also permit “single-member” LLCs, those having only one owner.
A few types of businesses generally cannot be LLCs, such as banks and insurance companies. Check your state’s requirements and the federal tax regulations for further information. There are special rules for foreign LLCs.
