How to Form an LLC: A Step-by-Step Guide for First-Time Business Owners

To form an LLC, you choose a unique business name, appoint a registered agent, file articles of organization with your state's Secretary of State and pay the filing fee, get a free EIN from the IRS, and write an operating agreement. Exact steps, forms, and fees vary by state, so confirm the details with your state's filing office before you start.

This article is general legal information, not legal advice. Laws vary by state and situation, and reading it does not create an attorney-client relationship. For advice about your case, talk to a licensed attorney.

Key Takeaways

• An LLC (limited liability company) separates your personal assets from your business debts and lawsuits, as long as you run it as a genuine separate entity.
• The core steps are the same across the country: name, registered agent, articles of organization, operating agreement, EIN, bank account, licenses, and ongoing compliance.
• State filing fees commonly run from about $50 to $500, and some states charge an annual fee or minimum franchise tax on top of that. Verify current amounts at your state's Secretary of State website.
• You can form a single-member LLC yourself in all 50 states, but multi-owner LLCs and anything involving investors or real estate are worth having an attorney review.
• The liability shield is not automatic protection. Commingling personal and business money or skipping basic recordkeeping can let a court hold you personally liable.
• After formation, most states require an annual or biennial report. Since March 2025, FinCEN has exempted companies created in the United States from beneficial ownership reporting; only certain foreign companies registered to do business here must file (fincen.gov/boi).

What an LLC Is and Why It Matters

An LLC is a business entity created under state law that gives owners (called members) limited liability protection while staying flexible to manage and tax. If the business is sued or cannot pay its debts, the members' personal assets, such as a home, car, or personal savings, are generally not at risk, provided the owners maintain the LLC properly.

Compared with a sole proprietorship, where you and the business are legally the same person, an LLC creates a legal wall between you and the company. Compared with a corporation, an LLC has far fewer formal requirements, usually no required board meetings or stock, and by default passes income straight through to the members' personal tax returns.

If you are still weighing entity types, read LLC vs. corporation: which business structure is right for you? before you file. The structure you pick affects taxes, investor appeal, and paperwork for years, so it is worth getting right the first time. You can also use the business entity comparison tool to see the trade-offs side by side.

How to Form an LLC: The Step-by-Step Process

The order below works in most states. Always confirm the specific forms, fees, and sequence at your state's Secretary of State (in a few states, the office has another name, such as the Department of State or Division of Corporations).

Step 1 — Choose and Check Your Business Name

Your LLC name has to be unique among registered entities in your state, and most states require it to include "LLC," "L.L.C.," or "Limited Liability Company."

1. Run a name availability search in your state's online business entity database (almost every Secretary of State offers one for free).
2. Search the U.S. Patent and Trademark Office's trademark database. A name can be available to register in your state and still infringe a federal trademark, which is a separate and costly problem.
3. Check whether a matching domain name and social media handles are available if an online presence matters to you.
4. Reserve the name if you are not ready to file. Many states let you hold a name for roughly 30 to 120 days for a small fee.

Step 2 — Appoint a Registered Agent

A registered agent is the person or company that receives legal documents (such as lawsuit papers) and official government notices for your LLC. Every LLC must have one.

The agent needs a physical street address (not a P.O. box) in your formation state and must be available during business hours. You can serve as your own agent if you have a qualifying in-state address, name a member, or hire a commercial registered agent service. Those services commonly charge somewhere around $50 to $300 per year; confirm current pricing directly. Many owners hire a service to keep their home address off the public record and to avoid missing a lawsuit notice while they are out.

Step 3 — File the Articles of Organization

The articles of organization is the document that legally creates your LLC. Some states call it a certificate of organization or certificate of formation. You file it with the Secretary of State, usually online.

Typical information the form asks for:

• LLC name
• Registered agent name and address
• Principal business address
• Whether the LLC is member-managed or manager-managed (and sometimes the names of members or managers)
• Duration (usually "perpetual")
• The organizer's signature

Filing fees vary widely by state, commonly in the $50 to $500 range. Processing can be same-day with online filing or take several weeks with paper, and many states sell expedited service. Once the state approves the filing, your LLC officially exists.

Step 4 — Write an Operating Agreement

An operating agreement is the internal rulebook for your LLC. It is usually not filed with the state, but it is one of the most important documents you will create. A few states (California is one) require LLCs to have one; most do not, but their LLC statutes effectively assume you have it.

A solid operating agreement covers ownership percentages, each member's capital contributions, how profits and losses are split, the management structure, the voting thresholds for major decisions, restrictions on transferring an ownership interest, buyout procedures, and how the LLC can be dissolved. Even a single-member LLC benefits from one, because it reinforces that the business is a separate entity, which supports your liability shield.

For multi-member LLCs or any business with outside investors, real estate, or professional services, have an attorney draft or review the agreement. For a deeper look at the provisions that matter most, see what an LLC operating agreement is and what it should include.

Step 5 — Get an EIN from the IRS

An Employer Identification Number (EIN) is your LLC's federal tax ID, similar to a Social Security number for a business. You apply free at IRS.gov, and the online application issues the number immediately for U.S.-based businesses. IRS Form SS-4 is the alternative for fax or mail.

A single-member LLC with no employees technically can use the owner's Social Security number for federal taxes, but most banks require an EIN to open a business account, and using one keeps your SSN off business paperwork. Get an EIN even if the IRS does not strictly require it.

Step 6 — Open a Business Bank Account

Open a dedicated business checking account and route all business income and expenses through it. Keeping business and personal money separate is one of the most important habits for protecting your liability shield, because commingling funds is one of the most common reasons courts pierce the corporate veil and hold owners personally liable.

Banks typically ask for your EIN, a copy of the approved articles of organization, your operating agreement, and a government-issued ID.

Step 7 — Get the Licenses and Permits You Need

Forming the LLC does not give you permission to operate. Depending on your industry and location, you may need licenses at the federal, state, county, and city levels. A home-based consultant and a restaurant face very different requirements.

• Check the U.S. Small Business Administration (SBA) site for federal licensing by industry.
• Search your state's business licensing portal for state-level and occupational licenses.
• Contact your city or county clerk for a local business license and any zoning or permit rules.

Step 8 — Stay Compliant Year After Year

An LLC is not "set it and forget it." Ongoing obligations usually include:

• Filing an annual or biennial report with the Secretary of State by the deadline. Missing it can trigger late fees and, eventually, administrative dissolution.
• Keeping a registered agent on file at all times.
• Updating your operating agreement when ownership or management changes.
• Keeping basic records: an ownership ledger, written records of major decisions, and financial statements.
• Meeting your tax duties, including state income tax, sales tax where it applies, and employer taxes if you hire.
• Filing a beneficial ownership report with FinCEN, but only if your company was formed under the law of another country and registered to do business in a U.S. state. Since March 2025, companies created in the United States are exempt (fincen.gov/boi).

Documents and Costs at a Glance

Item	What It Is	Typical Cost	Where It Comes From
Articles of Organization	Document that creates the LLC	About $50–$500 (varies by state)	State Secretary of State
Registered Agent	Receives legal and government notices	$0 if you serve; about $50–$300/yr for a service	You, a member, or a commercial service
Operating Agreement	Internal governance rulebook	$0 DIY; attorney fees vary	You or a business attorney
EIN	Federal tax ID number	Free	IRS (IRS.gov)
Business License/Permits	Permission to operate	Varies widely	Federal, state, county, or city
Annual/Biennial Report	Ongoing state compliance filing	Varies by state	State Secretary of State

Do not rely on any fee figure you read online, including the ranges above, without checking the current number against your state's official source. Fees change, and several states add an annual fee or minimum franchise tax separate from the formation cost.

Deadlines to Watch (and Verify)

Deadlines vary by state and entity, and you must confirm each one with the relevant agency. Several commonly matter:

• Annual or biennial report deadline. Many states tie it to your formation date or a fixed calendar date. Missing it risks penalties and administrative dissolution.
• State franchise tax or annual LLC fee. Some states (California's annual LLC tax is a well-known example) impose a recurring charge with its own due date.
• Beneficial ownership reporting under the Corporate Transparency Act. No deadline applies to an LLC formed in the United States. FinCEN exempted U.S.-created companies in March 2025 and made the exemption permanent in an August 2026 final rule; the filing deadlines now apply only to certain foreign companies registered to do business here (fincen.gov/boi).
• Tax elections. If you ever want your LLC taxed as an S-corporation, IRS Form 2553 has its own timing rules. Confirm current deadlines with the IRS and a tax professional.

Treat every date above as something to verify, not a fixed rule. The penalty for missing a compliance deadline is often far larger than the fee itself.

Common Mistakes First-Time Owners Make

• Commingling money. Paying personal bills from the business account (or the reverse) weakens your liability protection more than almost anything else.
• Skipping the operating agreement. Without one, your state's default rules govern, and they may not match what you and your co-owners actually intended.
• Forgetting the registered agent. If your agent moves or resigns and you do not update the state, you can miss a lawsuit and lose by default.
• Ignoring annual reports. Administrative dissolution can quietly strip your liability shield while you keep operating.
• Assuming the LLC covers licensing. Formation and licensing are separate. You can have a valid LLC and still be operating illegally without the right permits.
• Confusing an LLC with an S-corp. An S-corp is a tax election, not an entity type. An LLC can elect S-corp tax treatment, but that is a separate decision with real tax consequences best discussed with a CPA.

When to Talk to a Lawyer

You can form a simple single-member LLC on your own, and many people do. Consider professional help when:

• Two or more people will own the business and need a fair operating agreement.
• Outside investors, partners, or sweat-equity arrangements are involved.
• The LLC will hold real estate or operate in a high-liability or licensed field.
• You are unsure whether an LLC, corporation, or S-corp election fits your goals.
• You plan to operate in more than one state and may need to register as a foreign entity.

Many business attorneys offer flat-fee LLC formation and operating-agreement packages, so the cost is often predictable. You can compare options through the business law practice-area hub or find a business law attorney near you.

State and Local Differences

The eight-step framework is consistent nationwide, but the details are not. States differ on filing fees, the name of the formation document, whether an operating agreement is required, whether they charge an annual fee or franchise tax, how often reports are due, and whether publication of formation is required (a handful of states, such as New York, require newspaper publication). Professionals such as lawyers, doctors, and accountants may need a Professional LLC (PLLC) instead of a standard LLC, depending on state rules.

If you operate in a state other than the one where you formed, you will likely need to register there as a foreign entity, which means a second set of fees and a registered agent in that state. Always confirm requirements with each state's filing office.

Frequently Asked Questions

How much does it cost to form an LLC?

The main cost is the state filing fee for your articles of organization, commonly somewhere from about $50 to $500 depending on the state. Some states also charge an annual fee or minimum franchise tax. If you hire an attorney to file and draft an operating agreement, expect additional professional fees. Confirm current amounts at your state's Secretary of State website, because fees change.

Can I form an LLC by myself?

Yes. A single person can form a single-member LLC in all 50 states. You file articles of organization, name a registered agent, get an EIN from the IRS, and ideally write an operating agreement even as the sole owner. Multi-owner LLCs and businesses with investors or real estate are usually worth having an attorney review.

How long does it take to form an LLC?

It depends on the state and filing method. Online filings are often processed the same day or within a few business days, while paper filings can take several weeks. Many states offer expedited processing for an extra fee. After the state approves your articles, getting an EIN online is instant.

Do I need an operating agreement if I'm the only owner?

It is strongly recommended even though most states do not require it for single-member LLCs (California is a notable exception that requires one). An operating agreement reinforces that your business is a separate legal entity, which supports your liability shield, and it documents how the business runs. Some banks and investors also ask to see it.

What is a registered agent, and can I be my own?

A registered agent receives legal documents and official notices for your LLC and must have a physical address in your formation state. You can act as your own agent if you have a qualifying in-state address and are available during business hours. Many owners hire a commercial service to keep their home address private and avoid missing a lawsuit notice.

Do I need an EIN for my LLC?

Most LLCs do. A single-member LLC with no employees can technically use the owner's Social Security number for federal taxes, but you will almost certainly need an EIN to open a business bank account, and using one keeps your SSN off business paperwork. The EIN is free and available instantly through IRS.gov.

Is an LLC the same as an S-corp?

No. An LLC is a business entity formed under state law, while an S-corp is a federal tax classification. An LLC can elect to be taxed as an S-corporation by filing the right IRS form if it qualifies, which can change how the owners are taxed. Because the tax effects are significant, talk to a CPA or tax attorney before making that election.

Where should I form my LLC, my home state or Delaware?

For most small businesses that operate locally, forming in your home state is simpler and cheaper. If you form in Delaware but operate elsewhere, you typically pay fees in both states and register at home as a foreign entity. Delaware's advantages matter most to companies seeking institutional investment or planning to go public. A business attorney can advise based on your goals.

Ready to Form Your LLC?

Forming an LLC is one of the most accessible legal steps a new business owner can take, but the details, from your operating agreement to ongoing compliance, can carry real consequences if they are wrong. If you have co-owners, investors, or any uncertainty about structure or taxes, talk with a licensed business law attorney in your state before you file. A short consultation now is far cheaper than fixing a problem later. Connect with a business law attorney near you to get started.
