A limited liability company (LLC) is a U.S. business structure created under state law that separates the owners’ personal assets from the debts and legal liabilities of the business, while letting the owners choose how the business is taxed. It is sometimes called a “limited liability corporation,” but that name is inaccurate: an LLC is not a corporation. It is a distinct entity type that combines the liability shield of a corporation with the flexible management and pass-through taxation of a partnership or sole proprietorship.

How an LLC works

An LLC comes into existence when its founders file articles of organization (called a certificate of formation in some states) with a state government. From that point, the LLC is a legal person separate from its owners. It can sign contracts, open bank accounts, own property, borrow money, hire employees, and sue or be sued in its own name.

The owners are members, and ownership is expressed as a membership interest rather than shares of stock. An LLC can have a single member or many. Individuals, corporations, foreign persons and other LLCs can generally be members, but banks and insurance companies cannot organize as LLCs. Wyoming passed the first U.S. LLC statute in 1977, and every state now permits the structure, though each writes its own rules.

Member-managed vs. manager-managed

An LLC chooses how it is run:

• Member-managed: the owners run the business directly and can bind the LLC in day-to-day dealings. This setup is typical of small companies whose owners all work in the business.
• Manager-managed: the members appoint one or more managers (who may or may not be members) to handle operations. Members who only want to invest stay passive.

The operating agreement sets these roles out. It is the private contract among members that covers ownership percentages, voting rights, how profits and losses are allocated, what happens when a member leaves or dies, and the duties of each member. It usually stays with the company and is not filed with the state. Without one, the state’s default LLC rules fill the gaps, and those rules may not match what the owners intended.

What limited liability covers, and what it does not

Limited liability means a member’s financial exposure to the company’s obligations is generally capped at what the member has invested in the business. If the LLC fails, creditors can collect from the LLC’s assets but, in most cases, not from the members’ homes, savings or personal accounts.

The shield does not cover everything:

• Personal guarantees. Lenders and landlords often ask small-business owners to sign a personal guarantee. A member who signs one is personally liable for that debt regardless of the LLC.
• Your own conduct. An LLC protects members from liability for the company’s debts and for other members’ actions, not from their own negligence or wrongdoing. A physician who practices through an LLC can still be personally liable for their own malpractice, though not for a colleague’s.
• Piercing the veil. Courts can disregard the LLC and hold members personally liable when the company is used to commit fraud, when personal and business funds are mixed, or when the LLC fails to meet its legal and reporting requirements.
• Certain taxes. Unpaid payroll taxes that were withheld from employees can create personal liability for the people responsible for paying them.

How an LLC is taxed

For federal income tax, the IRS does not treat “LLC” as a tax category. Instead it applies default classifications that the LLC can change by election:

Under pass-through treatment, the LLC itself pays no federal income tax. Each member reports their share of profit or loss and pays tax at their own rate. This avoids the double taxation of a C corporation, where profits are taxed at the corporate level and then taxed again when paid to shareholders as dividends. Losses can offset a member’s other income, but generally only up to the member’s investment (tax basis) in the LLC.

Pass-through members who are active in the business also generally owe self-employment tax (Social Security and Medicare) on their share of earnings. Some owners elect S corporation status partly to manage this, since S corporation owners who work in the business are paid a salary subject to payroll tax and can receive remaining profits as distributions. State taxes are separate: some states charge LLCs an annual fee or franchise tax regardless of federal treatment.

Pay to members depends on the tax setup. In an LLC taxed as a corporation, members who work in the business can be paid wages that the company deducts as operating expenses. In a pass-through LLC, members usually take draws or guaranteed payments rather than W-2 wages.

Worked example (hypothetical)

Assume a two-member LLC with default partnership taxation and an operating agreement that allocates profit 60/40. The company earns $100,000 of net profit for the year and distributes $30,000 in cash.

• The LLC files Form 1065 but pays no federal income tax.
• Member A reports $60,000 of income and Member B reports $40,000 on their personal returns, even though only $30,000 was actually distributed. Pass-through members are taxed on their allocated share, not on the cash they receive.

Now assume the same LLC owes a supplier $250,000 and holds only $80,000 of assets when it closes. The supplier can claim the $80,000. Unless a member personally guaranteed the debt or a court pierces the veil, the remaining $170,000 cannot be collected from the members’ personal assets.

Forming an LLC

Requirements vary by state, but formation usually follows these steps:

1. Choose a name. It must be distinguishable from other registered businesses in the state and usually must include “LLC,” “L.L.C.” or “Limited Liability Company.”
2. Appoint a registered agent. This is a person or company with an address in the state that accepts legal papers and official government notices on the LLC’s behalf.
3. File articles of organization with the state and pay the state’s filing fee. The document typically lists the LLC’s name, address, registered agent, management structure and sometimes members or purpose.
4. Sign an operating agreement. Some states require one.
5. Get an employer identification number (EIN) from the IRS. An EIN is needed for a multi-member LLC, for hiring employees, and in practice for opening most business bank accounts.
6. Handle ongoing compliance: local licenses and permits, state annual or biennial reports, and any state franchise taxes. Missing these filings can lead the state to revoke the LLC’s good standing.

Members fund the business through capital contributions of cash, property or services, and the operating agreement records what each member put in.

Benefits of an LLC

Beyond the liability shield, the choice of tax treatment and flexible management described above, an LLC offers:

• Business deductions. Ordinary business expenses reduce taxable income, on the LLC’s return or the members’ returns depending on the tax election.
• Credibility. Operating as a registered entity can make a small business look more established to customers, lenders and suppliers than an unregistered sole proprietorship.

Limitations of an LLC

• Continuity. Depending on state law and the operating agreement, an LLC may have to dissolve when a member dies, goes bankrupt or leaves, while a corporation can exist indefinitely. A business continuation or buy-sell provision lets remaining members carry on and buy out the departing interest.
• State costs. Filing fees, annual reports and franchise taxes vary widely and recur every year in many states.
• Raising outside capital. Venture investors often prefer corporations, and an LLC cannot list on a stock exchange as an LLC. Founders aiming for an IPO usually form or convert to a corporation.
• Agreement risk. A vague or missing operating agreement can leave roles, voting and profit splits disputed. The agreement may also set penalties for members who fail to make promised capital contributions.

LLC vs. other business structures

LLC vs. partnership. Both can pass profits and tax obligations through to their owners. The key difference is liability: in a general partnership, each partner can be personally liable for the partnership’s debts and for other partners’ actions. An LLC shields its members.

LLC vs. sole proprietorship. A sole proprietorship needs no state filing, but the owner and the business are legally the same, so business debts are personal debts. A single-member LLC is taxed much like a sole proprietorship by default while adding the liability shield.

LLC vs. corporation. A corporation issues stock, is managed by a board of directors and officers, and must follow stricter formalities. A C corporation pays its own income tax. An LLC offers similar liability protection with lighter administration, with no mandatory board, annual shareholder meetings or bylaws in most states, and it can choose to be taxed as a corporation without becoming one.

LLC vs. S corporation. These are often confused because they are not the same kind of thing. An LLC is a legal entity formed under state law. An S corporation is a federal tax status. An eligible LLC can elect S corporation taxation and remain an LLC legally.

LLC vs. LLP and PLLC. A limited liability partnership (LLP) is a partnership form, often limited by state law to licensed professionals such as lawyers and accountants. A professional LLC (PLLC) is a variant some states require for licensed professions. In both, members stay liable for their own professional errors.

Examples of LLCs

LLCs range from one-person freelance businesses to large private companies. Common uses include single-member LLCs for consultants and contractors, multi-member LLCs for small businesses with partners, family LLCs that hold real estate or investments across generations, holding companies that own other entities, and physicians’ groups. Large privately held companies also use the form; The Wonderful Company LLC and Pilot Travel Centers LLC are two examples.

FAQs

The Bottom Line

An LLC suits small business owners, freelancers, partners and families who want personal asset protection without the formalities of a corporation. The protection holds only when members keep finances separate, stay current on state filings and avoid personal guarantees where possible. Founders planning to raise venture capital or go public usually form or convert to a corporation, and every LLC benefits from a clear operating agreement.
