A limited liability company, or LLC, is a business structure that separates the owners from the business in two ways. It shields personal assets from most business debts and lawsuits, and it lets profits pass through to the owners' tax returns without a separate corporate tax bill. Those two features explain why the LLC is the default choice for many small businesses in the United States. Forming one is mostly paperwork, but the order of the steps matters.
What an LLC Is and Is Not
An LLC is a legal entity created under state law, not federal law. Each state has its own limited liability company act, and the rules on names, filing, fees, and annual reports differ from state to state. The Internal Revenue Service does not create LLCs, but it does decide how they are taxed. By default, a single-member LLC is treated as a disregarded entity and a multi-member LLC as a partnership, unless the owners elect corporate tax treatment by filing the appropriate IRS form.
An LLC is not a corporation. It does not issue stock, it is not required to hold formal board meetings, and it does not file the same federal tax return as a C corporation. It is also not a guarantee of limited liability. Owners can lose protection if they personally guarantee a loan, commit fraud, or fail to keep the business and personal finances separate.
Step 1: Decide Where to Form the LLC
Most people form an LLC in the state where they actually live and operate. That is usually the simplest and cheapest choice, because the company must register as a foreign LLC in any other state where it does substantial business. Choosing a state like Delaware, Wyoming, or Nevada can make sense for certain companies with outside investors or specific tax goals, but it adds a second registration and often a registered agent in each state. The Small Business Administration at sba.gov recommends weighing the cost of doing business in each state, not just the filing fee.
Step 2: Choose a Name
State law generally requires the name to include the words limited liability company or an abbreviation such as LLC or L.L.C. The name must be distinguishable from other registered entities in the state, and it usually cannot include words the state reserves, such as bank, insurance, or trust. Search your secretary of state's business database before filing. Most states also require a registered agent, a person or company with a physical address in the state who can accept legal documents on the LLC's behalf.
Step 3: File the Formation Document
The core filing is called articles of organization or a certificate of formation. It goes to the secretary of state or the equivalent business filing office, and it typically asks for the LLC's name, address, registered agent, and the name of the organizer. Most states accept the filing online. Filing fees vary widely and are set by each state, so check your state's fee schedule directly. Some states also require a newspaper notice or an initial report.
Step 4: Adopt an Operating Agreement
An operating agreement is the internal rulebook for the LLC. It covers ownership percentages, how profits and losses are split, how decisions are made, what happens when an owner leaves, and how the company can be sold or dissolved. Many states do not require an operating agreement for an LLC to exist, but courts and lenders often look for one when ownership is disputed. Even a single-member LLC benefits from a written agreement that confirms the owner's control and keeps the entity distinct from the person.
Step 5: Get an EIN
An Employer Identification Number is a federal tax identifier issued by the IRS. Banks usually require one to open a business account, and it is needed to hire employees and file certain returns. Applying on the IRS website at irs.gov is free. Avoid third-party sites that charge for a service the IRS provides at no cost.
Step 6: Register for State Taxes and Licenses
Depending on the business, you may need a state sales tax permit, a business license, a professional license, or a local zoning or occupancy permit. Some states require the LLC to register with the state tax department even if it has no employees. The SBA's business guide and your state's small business office can help you build a checklist for your industry and location.
Step 7: Handle Ongoing Requirements
Formation is not the end of the process. Most states require an annual or biennial report, and some impose a franchise tax or a minimum fee. Missed reports can lead to late penalties or administrative dissolution. Keep business records, a separate bank account, and current contact information on file with the state.
Common Business Structures Compared
| Structure | Liability protection | Tax treatment | Formation |
|---|---|---|---|
| Sole proprietorship | None; owner is personally liable | Owner reports income on a personal return | No state filing required |
| General partnership | None; partners are personally liable | Pass-through; partnership return filed | Usually no state filing required |
| LLC | Generally limited to the owners' investment | Pass-through by default; corporate election available | Articles filed with the state |
| Corporation | Limited for shareholders | C corporation pays entity-level tax; S election available | Articles filed with the state |
Single-Member and Multi-Member LLCs
A single-member LLC has one owner and is usually taxed as a disregarded entity, which means the owner reports business income and expenses on Schedule C of a personal return. A multi-member LLC is usually taxed as a partnership and files an informational return, with each member receiving a Schedule K-1. Either form can elect to be taxed as an S corporation or a C corporation, but the election has payroll and reporting consequences that are worth discussing with a tax professional.
Mistakes to Avoid
- Filing in a different state without understanding the extra registration and tax obligations.
- Using a name that conflicts with an existing entity or trademark.
- Mixing personal and business funds, which can undermine liability protection.
- Forgetting annual reports and franchise taxes.
- Assuming an LLC removes the need for insurance, licenses, or a written contract.
Where the Rules Come From
Federal tax treatment is set by the Internal Revenue Code and explained on irs.gov. Formation, naming, registered agents, and annual reports are governed by each state's LLC act and administered by the secretary of state. Business licensing is split among state, county, and city agencies. Because those rules change and differ by location, confirm the current requirements with your state's official business filing office before you file.
