Definition and overview
A Limited Liability Company (LLC) is a hybrid US business structure created by state statute. LLCs combine the personal liability protection of corporations with the tax simplicity and operational flexibility of partnerships and sole proprietorships. The LLC is the most popular business structure for small businesses in the United States. The concept is foundational to US business law and tax practice. Most founders encounter limited liability company (llc) either at formation, during major business changes, or in connection with compliance filings.
History and legal basis
Wyoming created the first LLC statute in 1977, modeling it after a similar entity in Germany. The IRS issued guidance in 1988 (Revenue Ruling 88-76) confirming that Wyoming LLCs would be treated as partnerships for federal tax purposes. By 1996, all 50 states and Washington DC had enacted LLC statutes. The IRS "check the box" regulations in 1997 finalized the modern tax classification system, allowing LLCs to elect their federal tax treatment.
