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.[1] Establishing such a company in Wisconsin is a rather straightforward process.

After settling on a name, you must prepare and file "articles of organization" with your state's LLC filing office. While most states use the term "articles of organization" to refer to the basic document required to create an LLC, some states call it a "certificate of formation" or "certificate of organization." To learn about the specific requirements of forming an LLC in your state, choose your state from the list below:
After you've completed the steps described above, your LLC is official. But before you open your doors for business, you need to obtain the licenses and permits that all new businesses must have to operate. These may include a business license (sometimes also referred to as a "tax registration certificate"), a federal employer identification number, a sellers' permit, or a zoning permit. For more on business licenses and permits, see the Licenses & Permits for Your Business area of Nolo's website.

File with the appropriate federal, state, and local governmental agencies. Depending on the business purpose of your LLC and the jurisdiction in which you organize, you may have to file additional forms relating to LLCs with certain governmental agencies. Each industry is regulated differently—as is each local jurisdiction—and so it is best to ask an attorney or accountant for assistance in this matter.
The governing document of the LLC is called an operating agreement, and it is within this document that the members lay out all important provisions, such as standards for LLC governance, ownership parameters, and rules around member changes (adding or removing members, or what happens in case of death or incapacity of a member). The operating agreement is an internal document and is an agreement amongst the members or owners, which means it is not recorded with the state.
You must report personal property holdings in detail and as requested or mandated. If nothing has changed from the prior year (no equipment was purchased or sold), then you may refer to your prior year's Business Property Statement filing in order to be consistent in completing the current Business Property Statement. If you failed to keep a copy of the prior year's filing, you may request a copy of it from the Assessor's Office.
