How to Form an LLC: Complete Step-by-Step Guide

Most business owners form their LLC in the state where they live and operate. However, some states offer specific advantages such as lower fees, stronger asset protection, or more favorable tax treatment.

Home State vs. Another State

If you form in a state other than where you do business, you will likely need to register as a foreign LLC in your home state anyway, which means paying fees in both states. For most small businesses, forming in your home state is the simplest and most cost-effective option.

Popular States for LLC Formation

• Wyoming — No state income tax, strong asset protection, low annual fees, and strong privacy protections for LLC owners.
• Delaware — Well-established business court system (Court of Chancery), flexible LLC laws, and decades of legal precedent.
• Nevada — No state income tax, no franchise tax, and strong charging order protections for multi-member LLCs.
• New Mexico — Low filing fees, no annual reports, and strong privacy protections.

Your LLC name must be unique within your state and typically must include a designator such as “LLC,” “L.L.C.,” or “Limited Liability Company.”

Naming Rules to Follow

• The name must be distinguishable from other business entities registered in your state.
• Most states prohibit words like “Bank,” “Insurance,” or “University” without special approval.
• Check domain name availability at the same time so your online presence matches your legal name.
• Consider trademarking your business name for additional protection across state lines.

Name Reservations

Most states allow you to reserve a business name for 60 to 120 days by filing a name reservation form and paying a small fee (typically $10–$50). This is useful if you are not ready to file your articles of organization yet but want to lock in your preferred name.

Every LLC is required to have a registered agent (also called a statutory agent or agent for service of process) in the state where it is formed. The registered agent receives legal documents, tax notices, and official government correspondence on behalf of the LLC.

Who Can Be a Registered Agent?

• An individual who is a resident of the state and has a physical street address (not a P.O. Box).
• A business entity authorized to do business in the state, such as a registered agent service company.
• You can serve as your own registered agent, but you must be available at the listed address during normal business hours.

Should You Use a Professional Service?

Professional registered agent services typically cost $50 to $300 per year. They are a good option if you work from home and want to keep your address private, if you travel frequently, or if your LLC is formed in a state where you do not have a physical presence.

The Articles of Organization (called a Certificate of Formation or Certificate of Organization in some states) is the document you file with your state to officially create your LLC. This is the single most important step in the formation process.

Information Typically Required

• LLC name and principal office address
• Registered agent name and address
• Names of the organizers or members
• Whether the LLC is member-managed or manager-managed
• Effective date (if different from the filing date)
• Duration of the LLC (perpetual or a specific term)

Filing Fees

Filing fees vary significantly by state, ranging from $40 in states like Kentucky to $500 in Massachusetts. Most states fall in the $50–$200 range. Many states offer online filing, which can speed up the process to as little as a few business days.

An EIN (also called a Federal Tax ID Number) is like a Social Security number for your business. It is issued by the IRS and is free to obtain. You will need an EIN if your LLC has more than one member, if you plan to hire employees, or if you want to open a business bank account (most banks require it).

How to Apply

• Online (recommended) — Apply at IRS.gov. The process takes about 10 minutes, and you receive your EIN immediately.
• By fax — Complete Form SS-4 and fax it to the IRS. You typically receive your EIN within four business days.
• By mail — Mail Form SS-4 to the IRS. Expect to wait four to six weeks for a response.

When an EIN Is Required

Even single-member LLCs with no employees should consider getting an EIN. It keeps your Social Security number off business documents, simplifies banking, and is required if you ever elect S-Corp taxation.

An operating agreement is an internal document that outlines how your LLC will be governed. While not all states legally require one, every LLC should have an operating agreement to clearly define ownership, responsibilities, and procedures.

Key Provisions

• Ownership percentages and capital contributions
• Profit and loss distribution
• Management structure and voting rights
• Rules for adding or removing members
• Dissolution procedures

Depending on your industry and location, you may need federal, state, and local business licenses or permits to operate legally. Failing to obtain the right licenses can result in fines or even closure of your business.

Common Types of Licenses

• General business license — Required by most cities and counties.
• Professional licenses — Required for certain professions like law, accounting, medicine, and real estate.
• Sales tax permit — Required if you sell taxable goods or services.
• Home occupation permit — May be required if you run your business from home.
• Health and safety permits — Required for food service, childcare, and similar businesses.
