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.
An important part of LLC formation is the registered agent. A registered agent must be a person who is located in the state in which you are forming your LLC. This is the person you designate to receive legal service of process, as well as government forms and notices, on behalf of your LLC. He or she must have a physical street address (not a P.O. box).
