A limited liability company, or LLC, is a business structure registered with a state that protects its owners’ personal assets from the company’s debts and lawsuits while letting profits flow through to the owners’ personal tax returns without a separate corporate-level tax. It is the most widely formed business entity in the United States because it combines the liability shield of a corporation with the tax simplicity and operational flexibility of a partnership. You create one by filing a short document with your state, deciding how it will be managed and taxed, and then running it with far fewer formalities than a traditional corporation requires.
Who Owns an LLC
The owners of an LLC are called members. The IRS allows members to be individuals, corporations, other LLCs, or foreign entities, and there is no cap on how many an LLC can have.1Internal Revenue Service. Limited Liability Company (LLC) One person can form a single-member LLC. A group of hundreds can form one together.
That openness is part of why LLCs edge out S-corporations for many small businesses. S-corps cap shareholders at 100 and limit ownership to U.S. citizens and residents. An LLC can bring in a corporate partner, a foreign investor, or a trust without restructuring.
How an LLC Is Managed
Every LLC runs under one of two management structures. In a member-managed LLC, all owners share day-to-day control and can bind the company. In a manager-managed LLC, the members appoint one or more managers, who may or may not be members themselves, to handle operations. Most states ask you to pick which structure applies when you file your formation document.2U.S. Small Business Administration. Basic Information About Operating Agreements
The document that actually governs how the business runs is the operating agreement, a private contract among the members. A good one sets ownership percentages, voting rights, how profits and losses are split, what happens when someone wants to leave, and how new members are admitted.2U.S. Small Business Administration. Basic Information About Operating Agreements Most states do not require you to file it anywhere; it stays between the members. Skipping it is still a mistake, because your state’s default LLC rules will fill in the gaps, and those defaults rarely match what the members intended.
Unlike a corporation, an LLC has no legal duty to hold annual board meetings, elect officers, or keep formal minutes. That lighter administrative load is a genuine advantage for small businesses. It also puts more weight on the operating agreement, since it is the one document that controls almost everything about how the company functions internally.
What Limited Liability Actually Protects
The core benefit of an LLC is the wall between the business and your personal property. If the company is sued or cannot pay its bills, creditors can reach the LLC’s bank accounts and assets, but generally not your personal savings, home, or car. Your exposure is limited to what you have put into the business.1Internal Revenue Service. Limited Liability Company (LLC)
That protection is not automatic. Courts can “pierce the veil” and hold members personally liable when the LLC is used as a personal piggy bank rather than a real business. The usual triggers are mixing personal and business funds in one account, failing to keep separate books, and starting the company with so little capital that it could never realistically pay its debts. Separate bank accounts, contracts signed in the LLC’s name, and basic financial records are the practical habits that keep the shield intact.
Charging Order Protection
The protection also runs the other direction. If a member personally owes money, say from a car accident judgment or a credit card debt, that member’s creditors generally cannot seize LLC assets or force the company to liquidate. In most states the only remedy available is a charging order, which lets the creditor collect whatever distributions would otherwise go to that member. The creditor gets no voting rights, no management authority, and no access to the books. One member’s personal financial trouble does not have to pull the whole business down with it.
Why You Still Need Insurance
Limited liability protects your personal assets. It does not protect the company’s. A big enough lawsuit can drain every dollar the LLC owns and effectively destroy the business even though your house is safe. General liability insurance, professional liability coverage, and commercial umbrella policies exist to fill that gap. Treating the LLC as your only line of defense is one of the more expensive mistakes a small business owner can make.
How an LLC Is Taxed
The IRS does not have a dedicated LLC tax classification. It assigns your LLC a tax identity based on how many members it has and whether you have filed an election to change the default.
Default Pass-Through Treatment
A single-member LLC is treated as a “disregarded entity,” meaning the IRS ignores it for income tax purposes. The owner reports all income and expenses on their personal return, usually on Schedule C.3Internal Revenue Service. Single Member Limited Liability Companies A multi-member LLC is treated as a partnership. It files an informational return on Form 1065, and each member gets a Schedule K-1 showing their share of profits, losses, and credits to carry over to their personal Form 1040.4Internal Revenue Service. LLC Filing as a Corporation or Partnership
Either way, the LLC itself pays no federal income tax. Profits are taxed once, on the members’ returns. This is pass-through taxation, and it is what the IRS applies by default unless you file paperwork asking for something different.1Internal Revenue Service. Limited Liability Company (LLC)
Electing Corporate Tax Treatment
An LLC can opt out of pass-through taxation. Filing Form 8832 with the IRS classifies the LLC as a C-corporation, which means the company pays corporate income tax on its profits and members are taxed again on any distributions.5Internal Revenue Service. About Form 8832, Entity Classification Election A qualifying LLC can instead file Form 2553 to elect S-corporation status, which keeps pass-through taxation but changes how the owners pay themselves and run payroll.6Internal Revenue Service. About Form 2553, Election by a Small Business Corporation
Self-Employment Tax
Pass-through taxation has a sting. Members of a pass-through LLC owe self-employment tax on their share of the company’s net earnings. The rate is 15.3%, split between 12.4% for Social Security and 2.9% for Medicare.7Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) For 2026, the Social Security portion applies to the first $184,500 of combined wages and net self-employment income. The Medicare portion has no cap.8Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security
This is the main reason some LLC owners elect S-corporation treatment. Under an S-corp election, members who work in the business pay themselves a reasonable salary subject to payroll taxes, and take additional profits as distributions that are not subject to self-employment tax. Whether it saves money depends on how much the business earns and what a reasonable salary looks like for the work being done. The payroll complexity has its own costs.
How You Form an LLC
Formation happens at the state level. There is no federal LLC registration. The steps are largely the same from state to state, though form names, fees, and small requirements vary.
Pick a Name
Your LLC name has to be distinguishable from other business entities already registered in your state. Nearly every state also requires the name to include a designator like “LLC,” “L.L.C.,” or “Limited Liability Company” so the public knows they are dealing with a limited liability entity. Check your state’s business name database before you file; most secretaries of state offer free online search tools.
Appoint a Registered Agent
Every LLC must have a registered agent, a person or company authorized to accept legal documents and official government notices for the LLC. The agent needs a physical street address in the state of formation, not a P.O. box, and has to be available during normal business hours to accept service of process. Many LLCs hire a commercial registered agent service rather than list a member’s home address, which would otherwise become part of the public record.
File the Formation Document
The formation document goes by different names depending on the state, Articles of Organization in most places and Certificate of Formation in others. It is a short form that typically asks for the LLC’s name, the registered agent’s name and address, whether the LLC will be member-managed or manager-managed, and the names of the organizers. You file it with the secretary of state or equivalent business filing office. Most states offer online filing, and paper filing by mail is usually still an option.
Get an EIN
A multi-member LLC needs a federal Employer Identification Number from the IRS because it files a partnership return. A single-member LLC does not technically need one if it has no employees and no excise tax obligations; the owner can use their Social Security number. Most single-member LLCs get an EIN anyway, because banks require one to open a business account and it avoids handing out your SSN to every vendor that needs a tax ID.3Internal Revenue Service. Single Member Limited Liability Companies The application is free and takes about five minutes on the IRS website.
What It Costs
Filing fees vary widely. Some states charge as little as $35, while others charge up to $500 for a standard filing. The national average is around $130. Expedited processing, which can cut approval time from weeks to days, costs extra in most states and sometimes doubles the base fee. These are one-time formation costs. The ongoing costs come later.
Keeping an LLC in Good Standing
Forming the LLC is the easy part. Keeping it alive requires attention to recurring obligations that trip up a surprising number of business owners.
Annual and Biennial Reports
Most states require LLCs to file periodic reports, every year in some states and every two years in others. The report updates the state on basic information like the LLC’s address, members or managers, and registered agent. Fees range from nothing in a handful of states to several hundred dollars elsewhere. A few states tack on an annual franchise tax.
Miss your filing deadline and the state will usually send a warning with a grace period. Ignore that too and the state can administratively dissolve your LLC. A dissolved LLC cannot legally conduct business; it can only wind down and liquidate. Anyone who keeps operating it during that period may be held personally liable for debts incurred. You can also lose your LLC’s name if another entity grabs it while you are dissolved. Reinstatement is usually possible, but it involves back fees, penalties, and paperwork that cost more than just filing the report on time.
Operating in Other States
If your LLC does business in a state other than where it was formed, that second state will likely require you to register as a “foreign LLC” through foreign qualification. You file a registration document, appoint a registered agent in that state, and pay another filing fee. What counts as “doing business” varies. Having a physical office, employees, or regular customer transactions in a state almost always triggers the requirement; occasional sales or attending a conference usually do not. Operating in a state without qualifying can result in fines and, in some states, being barred from using the courts there to enforce your contracts.
Federal Beneficial Ownership Reporting
The Corporate Transparency Act originally required most LLCs to report their beneficial owners to the Financial Crimes Enforcement Network (FinCEN). As of March 2025, FinCEN issued an interim final rule exempting all domestic entities from this reporting requirement.9Financial Crimes Enforcement Network. Beneficial Ownership Information Reporting The Treasury Department separately announced it would not enforce penalties or fines against U.S. citizens or domestic reporting companies under the existing or forthcoming rules.10U.S. Department of the Treasury. Treasury Department Announces Suspension of Enforcement of Corporate Transparency Act Against U.S. Citizens and Domestic Reporting Companies Only foreign entities registered in the United States are currently required to file. This area has shifted quickly, so if you form a new LLC it is worth checking FinCEN’s website to confirm the rules have not changed again.
