Limited Liability Company (LLC)
A Limited Liability Company (LLC) is a U.S. business structure that shields owners’ personal assets from the company’s debts and lawsuits. At the same time, it lets business profits pass through to the owners’ personal tax returns. In short, an LLC blends the liability protection of a corporation with the tax simplicity and operating flexibility of a partnership.
States govern LLC formation, so exact rules vary slightly from one state to the next. However, the core structure stays consistent across the U.S.
Who Owns an LLC?
LLC owners go by the term members, not shareholders. Depending on how many people own it, an LLC falls into one of two categories:
- Single-member LLC: one owner, and the IRS taxes it like a sole proprietorship by default
- Multi-member LLC: two or more owners, and the IRS taxes it like a partnership by default
Members can include individuals, corporations, other LLCs, and even foreign entities. Most states also place no cap on how many members an LLC can have.
How Does Liability Protection Work?
The phrase “limited liability” describes a legal wall between the business and its owners. Because of this wall, creditors generally cannot pursue a member’s house, car, or personal savings if the LLC can’t pay its debts or loses a lawsuit. Instead, members typically risk only the money they’ve invested in the company.
Still, this protection has limits. If members mix personal and business finances, commit fraud, or ignore their state’s basic LLC formalities, a court can “pierce the corporate veil” and hold them personally liable.
LLC vs. Corporation vs. Sole Proprietorship

How Do LLCs Get Taxed?
By default, the IRS treats an LLC as a pass-through entity, which means the following:
- A single-member LLC reports profits and losses directly on the owner’s personal return (Schedule C).
- A multi-member LLC instead files a partnership return (Form 1065) and issues each member a Schedule K-1.
Since the LLC itself doesn’t pay federal income tax, members avoid the “double taxation” that C corporations face, where the IRS taxes profits once at the corporate level and again when the company distributes them to owners.
That said, LLCs aren’t locked into this default setup. For example, an LLC can instead elect to be taxed as an S corporation or C corporation, which may lower self-employment tax exposure for owners who actively work in the business. Because these elections carry real trade-offs, it’s worth consulting a tax professional before making one.
How Do You Form an LLC?
Forming an LLC generally involves these steps:
- First, choose a unique, state-compliant business name.
- Next, file Articles of Organization with the state.
- Then, appoint a registered agent to receive legal documents on the company’s behalf.
- After that, draft an operating agreement that spells out ownership, management, and profit-sharing rules.
- Finally, pay the state’s filing fee, along with any ongoing annual fee the state requires.
