A limited-liability company ("LLC") is commonly referred to as a "hybrid" business structure, meaning that it shares characteristics of both a corporation and a sole proprietorship. It allows its owners to insulate themselves from personal liability for business debts, does not require the payment of separate business taxes (the tax "passes through" to its owners), allows for a great deal of flexibility with regards to its organizational structure, and is subject to fewer regulations and restrictions than are other types of business structures. Establishing such a company in Wisconsin is a rather straightforward process.
Another important component when you are determining how to form an LLC is the creation of an LLC operating agreement. While operating agreements are not required under state law when forming an LLC and do not have to be filed with the state, they are very important documents to create because they help you and any other members of the LLC organize your business, plan for the future, and put all pertinent facts in writing.
