A limited liability company (LLC) is a flexible form of enterprise that blends elements of partnership and corporate structures. It is a legal form of company that provides limited liability to its owners in the vast majority of United States jurisdictions. LLCs do not need to be organized for profit.^{[citation needed]}

Often incorrectly called a "limited liability corporation" (instead of company), it is a hybrid business entity having certain characteristics of both a corporation and a partnership or sole proprietorship (depending on how many owners there are). An LLC, although a business entity, is a type of unincorporated association and is not a corporation. The primary characteristic an LLC shares with a corporation is limited liability, and the primary characteristic it shares with a partnership is the availability of pass-through income taxation. It is often more flexible than a corporation, and it is well-suited for companies with a single owner.

LLC members are subject to the same alter ego piercing theories as corporate shareholders. However, it is more difficult to pierce the LLC veil because LLCs do not have many formalities to maintain. So long as the LLC and the members do not commingle funds, it would be difficult to pierce its veil. Membership interests in LLCs and partnership interests are also afforded a significant level of protection through the charging order mechanism. The charging order limits the creditor of a debtor-partner or a debtor-member to the debtor’s share of distributions, without conferring on the creditor any voting or management rights. Limited liability company members may, in certain circumstances, also incur a personal liability in cases where distributions to members render the LLC insolvent.
