How to Set Up an LLC (Step-by-Step 2026)

Learning how to set up an LLC is one of the smartest first moves you can make as a new business owner. A limited liability company (LLC) gives you a legal shield between your personal assets and your business debts, flexible tax treatment, and the credibility that comes with a registered entity, all without the heavy compliance burden of a corporation. The good news is that the process is more straightforward than most people expect, and you can complete most of it yourself in an afternoon. This guide walks you through every step in plain English so you know exactly what to do, what it costs, and where the common pitfalls hide.

To set up an LLC, choose your state, pick and clear a unique business name, appoint a registered agent, file Articles of Organization with the state, get an EIN from the IRS, draft an operating agreement, open a business bank account, and secure any required licenses. Filing fees and rules vary by state.

Step 1: Choose your state of formation

Your first decision is where to form the company. Most owners should simply form in the state where they live and do business, because that is where you will be earning income and meeting customers. Forming in a “tax-friendly” state like Delaware, Nevada, or Wyoming sounds appealing, but if you operate elsewhere you will usually have to register as a foreign LLC in your home state anyway, paying two sets of fees and dealing with two sets of paperwork. Each state sets its own filing fees, annual report requirements, and franchise taxes, so confirm the specifics with your Secretary of State office before you commit. If you have multi-state operations or significant assets, this is exactly the kind of decision worth discussing with a tax professional first.

Step 2: Pick a name and check availability

Your LLC name has to be unique within your state and must include a designator such as “LLC,” “L.L.C.,” or “Limited Liability Company.” Run a search on your state’s business entity database to confirm the name is not already taken, and avoid restricted words (like “bank” or “insurance”) that trigger extra approvals. It is also wise to check that a matching domain name and social media handles are free so your brand stays consistent online. If you have settled on a name but are not ready to file yet, many states let you reserve it for a small fee for a set period.

Step 3: Appoint a registered agent

Every LLC must name a registered agent, a person or company with a physical address in the state who agrees to receive legal documents and official mail on the company’s behalf during business hours. You can act as your own registered agent, appoint a trusted individual, or hire a commercial registered agent service for an annual fee. Many owners choose a service to keep their home address off public records and to make sure they never miss a time-sensitive legal notice such as a lawsuit or state filing reminder.

Step 4: File your Articles of Organization

This is the document that legally creates your LLC. The Articles of Organization (called a “Certificate of Formation” in some states) typically asks for your company name, principal business address, registered agent details, the names of the members or managers, and the management structure (member-managed or manager-managed). You file it with the Secretary of State, usually online, and pay the state filing fee. Because these fees vary widely by state, always check the current amount on your state’s official website before you submit. Once the state approves your filing, your LLC officially exists.

Step 5: Get an EIN from the IRS

An Employer Identification Number (EIN) is your business’s federal tax ID, the equivalent of a Social Security number for your company. You will need it to open a business bank account, hire employees, and file taxes. Applying is free directly through the IRS, and most online applications are approved instantly. You can apply on the IRS website in a few minutes. Be cautious of third-party sites that charge a fee for something the IRS provides at no cost.

Step 6: Draft an operating agreement

An operating agreement is an internal document that spells out how your LLC is owned and run: who the members are, how profits and losses are split, how decisions get made, and what happens if a member leaves or the company dissolves. Not every state legally requires one, but you should create one anyway, even as a single-member LLC. It reinforces your liability protection by showing your business is a genuinely separate entity, and it prevents disputes by putting expectations in writing. Banks and investors often ask to see it too.

Step 7: Open a business bank account

Keeping business and personal finances separate is not optional, it is essential to maintaining the liability shield an LLC provides. Mixing funds (known as “commingling”) can let a court “pierce the corporate veil” and hold you personally liable. Once you have your approved Articles of Organization and your EIN, open a dedicated business checking account. Bring your formation documents, EIN confirmation, and operating agreement, as most banks will ask for all three. A separate account also makes bookkeeping and tax filing dramatically simpler at year-end.

Step 8: Secure licenses and permits

Forming the LLC does not automatically give you permission to operate. Depending on your industry and location, you may need a general business license, professional licenses, sales tax permits, or local zoning and health permits. Requirements differ at the federal, state, county, and city level, so check with your state and local authorities to confirm what applies to you. Operating without a required license can lead to fines or forced closure, so handle this before you start trading.

How an LLC is taxed: default rules and the S-corp option

By default, an LLC is a “pass-through” entity, meaning the business itself does not pay federal income tax. Instead, profits and losses flow through to the owners’ personal tax returns. A single-member LLC is taxed like a sole proprietorship, and a multi-member LLC is taxed like a partnership. Owners typically pay self-employment tax on their share of the profits. Once your net earnings grow, you may benefit from electing S-corporation status by filing Form 2553 with the IRS, which can reduce self-employment taxes by letting you split income between a reasonable salary and distributions. This election is not right for everyone, and the savings depend on your numbers, so review your situation with a qualified advisor.

The LLC setup process, step by step

Here is the complete sequence in one quick checklist you can work through in order:

1. Choose the state where you will form and operate the LLC.
2. Select a unique, compliant business name and confirm it is available.
3. Appoint a registered agent with a physical address in your state.
4. File your Articles of Organization with the Secretary of State and pay the fee.
5. Apply for a free EIN directly from the IRS.
6. Draft and sign an operating agreement.
7. Open a dedicated business bank account.
8. Obtain all required federal, state, and local licenses and permits.
9. Decide on your tax treatment, including whether to elect S-corp status.

Mistakes to avoid when forming your LLC

A few common errors can undermine the protection and savings your LLC is supposed to deliver. Watch out for these:

• Commingling funds. Using one account for business and personal spending is the fastest way to lose your liability protection.
• Skipping the operating agreement. Even single-member LLCs benefit from one, both for legal clarity and credibility.
• Forming in the “wrong” state. Choosing Delaware or Wyoming when you operate elsewhere often means paying double fees as a foreign entity.
• Forgetting ongoing compliance. Most states require annual or biennial reports and fees; miss them and your LLC can be administratively dissolved.
• Overlooking licenses. Many owners assume formation is enough and start operating without the permits their industry requires.
• Paying for a free EIN. The IRS never charges for an EIN, so skip the middleman sites.

Frequently asked questions

How much does it cost to set up an LLC?

Costs vary significantly by state. The main expense is the state filing fee for your Articles of Organization, which can range from under one hundred dollars to several hundred, plus possible annual report fees and franchise taxes. Optional costs include a registered agent service or professional help. Always confirm current fees with your state and check IRS.gov for federal requirements.

How long does it take to set up an LLC?

If you understand how to set up an LLC and file online, your state may approve the Articles of Organization within a few business days, and some states offer same-day or expedited processing for an extra fee. Getting your EIN from the IRS is usually instant. Paper filings and busy filing seasons can extend the timeline, so check your state’s current processing times.

Do I need a lawyer to form an LLC?

No, you can form an LLC yourself, and many owners do. That said, a tax advisor or attorney is valuable if you have multiple owners, complex ownership arrangements, multi-state operations, or you are weighing an S-corp election. Professional guidance early can prevent costly mistakes later.

Can a single person form an LLC?

Yes. A single-member LLC is one of the most popular structures for solo entrepreneurs and freelancers. It provides liability protection and, by default, is taxed like a sole proprietorship, keeping things simple while still separating your personal and business finances.

What is the difference between an LLC and a corporation?

An LLC offers liability protection with far less administrative formality and flexible pass-through taxation, while a corporation has stricter requirements such as boards, bylaws, and shareholder meetings, and is taxed differently. Many small businesses choose an LLC for its simplicity, then elect S-corp tax treatment as they grow.
