Depending on elections made by the LLC and the number of members, the IRS will treat an LLC as either a corporation, partnership, or as part of the LLC’s owner’s tax return (a “disregarded entity”). Specifically, a domestic LLC with at least two members is classified as a partnership for federal income tax purposes unless it files Form 8832 and affirmatively elects to be treated as a corporation. For income tax purposes, an LLC with only one member is treated as an entity disregarded as separate from its owner, unless it files Form 8832 and elects to be treated as a corporation. However, for purposes of employment tax and certain excise taxes, an LLC with only one member is still considered a separate entity.
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.
In the United States, a limited liability company is a business entity type that combines the pass-through taxation of a partnership or sole proprietorship with the limited liability of a corporation, creating the best of both worlds for business owners. LLCs have rapidly become one of the most popular business structures for new and small businesses, largely because they are considered to be simpler and more flexible than a corporation.
