How to Start an LLC: A Complete State-by-State Guide

Starting a Limited Liability Company (LLC) is one of the most popular ways to establish a business in the United States. With over 2 million LLCs registered across the 50 states, entrepreneurs appreciate the liability protection, tax flexibility, and simplified management structure that an LLC offers. However, the process of forming an LLC varies significantly from state to state, and understanding the specific requirements for your location is essential to getting it right the first time.

This comprehensive guide walks you through every step of starting an LLC, from choosing a name to filing your articles of organization, and reveals the actual costs you can expect in your state.

Step 1: Choose and Reserve Your LLC Name

Your LLC name is one of the first—and most important—decisions you’ll make. Every state requires that your business name be unique and distinguishable from other registered entities in that state’s records. The name must also include the words “Limited Liability Company,” “LLC,” or an approved abbreviation like “L.L.C.” in most states.

To start, search your state’s Secretary of State database to ensure your desired name is available. Most states offer free name searches online. Once you’ve confirmed availability, many states allow you to reserve the name for 30 to 120 days—a process that typically costs between $10 and $50. Reserving your name gives you exclusive rights while you prepare your articles of organization.

Pro tip: Choose a name that clearly describes your business and avoids words that require professional licensing (like “attorney” or “bank”) unless you hold those licenses. Avoid generic terms and ensure the name is easy to spell and remember for customers.

Step 2: Prepare and File Your Articles of Organization

The articles of organization is the official document that creates your LLC. This filing is submitted to your state’s Secretary of State office and legally establishes your business. The articles typically include your company name, principal place of business, registered agent information, the names of members (owners), and the effective date of formation.

Filing fees for articles of organization range significantly by state—from as low as $50 in states like Wyoming and New Mexico to $500 or more in states like Delaware and New York. Most states charge between $100 and $300. You can file online through your Secretary of State’s website, by mail, or in some cases, in person at the state office. Online filing is fastest, typically processing within 2 to 7 business days, while mail filings may take 1 to 4 weeks.

Many entrepreneurs hire a business formation service to prepare and file their articles, which adds $50 to $300 to the total cost but reduces the risk of errors and accelerates the process.

Step 3: Appoint a Registered Agent and Obtain an EIN

Every LLC must designate a registered agent—a person or company responsible for receiving legal documents and official notices on behalf of your business. This can be you, a co-owner, or a professional registered agent service. If you use a professional service, expect to pay $100 to $300 annually.

Next, obtain an Employer Identification Number (EIN) from the Internal Revenue Service. An EIN is a nine-digit number that identifies your business for federal tax purposes, much like a Social Security number for individuals. Applying for an EIN is free and takes just 15 minutes online through the IRS website. You can even receive your EIN immediately upon approval, allowing you to open a business bank account right away.

Step 4: Create an Operating Agreement and Obtain Licenses

While not required by most states, an operating agreement is a critical document that outlines how your LLC will be managed, how profits will be distributed, and the rights and responsibilities of each member. This document protects you in disputes and clarifies expectations. Many banks require an operating agreement before opening a business account. You can create an operating agreement yourself for free using templates, or hire an attorney for $300 to $1,000 for a customized version.

Additionally, depending on your industry and location, you may need to obtain business licenses, permits, and certifications. Common licenses include general business licenses ($50 to $200), professional licenses (highly variable by field), health permits, and zoning permits. Contact your local city or county clerk’s office to determine which licenses apply to your business.

Step 5: Set Up Business Banking and Accounting

Once your LLC is officially formed, open a dedicated business bank account in your LLC’s name using your EIN. This separates your personal and business finances—essential for maintaining limited liability protection and simplifying taxes. You’ll need your articles of organization, EIN letter, and government-issued ID to open an account. Most banks offer free or low-cost business checking accounts.

Choose an accounting system to track income and expenses from day one. Simple options like QuickBooks Self-Employed or Wave Accounting cost $0 to $30 monthly, while professional bookkeeping services run $500 to $2,500 annually depending on transaction volume.

Understanding State-Specific LLC Formation Costs

The total cost to start an LLC varies dramatically by state. Wyoming, South Dakota, and Nevada offer the lowest filing fees at $50 to $90, making them popular choices for business formation. However, some states charge additional fees for name reservation, publication in newspapers, or annual reports that add to the upfront cost.

New York requires publication in newspapers, adding $500 to $2,000 to formation costs. California charges $120 to file but imposes an annual franchise tax of $800 minimum, making California one of the most expensive states for ongoing LLC compliance. Texas, Florida, and Illinois fall in the mid-range with filing fees between $100 and $300 and no ongoing annual fees.

Frequently Asked Questions

How long does it take to form an LLC?

Formation timelines vary by state and filing method. Online filing typically takes 2 to 7 business days, while mail submissions may require 1 to 4 weeks. Some states like Nevada and Wyoming offer expedited filing for an additional fee, completing formation in 24 hours or less. Having all required information ready and avoiding errors speeds up the process significantly.

Can I start an LLC by myself, or do I need a partner?

You can absolutely form an LLC as a solo founder; these are called single-member LLCs. Single-member LLCs provide the same liability protection and tax flexibility as multi-member LLCs, making them ideal for freelancers and solo entrepreneurs. There’s no minimum number of members required in any state.

What’s the difference between an LLC and an S-Corp?

An LLC is a business structure that focuses on liability protection and flexible taxation, while an S-Corp is a tax classification that can help reduce self-employment taxes if your business is profitable. Many business owners form an LLC and then elect S-Corp tax treatment with the IRS. Consult a tax professional to determine which option saves you the most money based on your specific income and deductions.

Do I need a lawyer to start an LLC?

A lawyer is not required to form an LLC, especially in straightforward situations. However, an attorney can be invaluable if you have multiple members, complex ownership structures, or industry-specific regulations. Many entrepreneurs successfully form LLCs using online resources and templates, spending $0 to $50, while legal guidance typically costs $500 to $2,000.

What happens after I file my articles of organization?

After filing, you’ll receive a confirmation notice or certificate of organization from your state’s Secretary of State, usually within 2 to 7 business days. Use this certificate and your EIN to open a business bank account, apply for licenses, and set up payroll. You’ll also need to remember ongoing compliance tasks like filing annual reports (required in most states) and paying any franchise taxes your state imposes.

Conclusion

Starting an LLC is an achievable goal that costs between $100 and $500 for state filing fees in most cases, with total formation expenses ranging from $300 to $2,000 when you factor in registered agent services, business licenses, and professional guidance. The specific costs depend on your state, industry, and whether you handle filings yourself or hire professionals.

By following the five steps outlined here—choosing a name, filing articles of organization, appointing a registered agent, creating an operating agreement, and setting up business banking—you’ll establish a legitimate LLC that protects your personal assets and provides tax flexibility.

Every state has unique requirements and fees, so it’s critical to understand the exact costs and timelines for your location before you begin.
