How to Start an LLC: A Complete Step-by-Step Guide for All 50 States

Starting a Limited Liability Company (LLC) is one of the most popular business structures chosen by entrepreneurs today. Whether you’re launching a side hustle, launching a consulting firm, or formalizing an existing operation, an LLC offers liability protection, tax flexibility, and simpler administration than a corporation. However, the process varies slightly by state, and understanding the specific requirements—along with accurate cost estimates—can save you thousands of dollars and months of confusion.

This guide walks you through every step of forming an LLC, from choosing your business name to filing your articles of organization and beyond. We’ll also help you understand the true costs involved, which range from under $50 in some states to $500 or more in others.

Step 1: Choose Your LLC Name and Verify Availability

Your LLC name is your business identity, and it must be unique within your state. Before you fall in love with a name, you need to verify it’s available and follows your state’s naming rules.

Start by checking your state’s Secretary of State website to search the business name database. Nearly all states require your LLC name to include the words “LLC,” “L.L.C.,” or “Limited Liability Company.” Some states have additional restrictions—for example, words like “bank,” “insurance,” or “attorney” may require special licenses or approval.

Reserve your name if you’re not ready to file immediately. Most states allow name reservations for 30 to 120 days, typically costing $10 to $50. This protects your chosen name while you finalize other details. If you plan to operate under a different name than your official LLC name, you’ll also need to file a DBA (Doing Business As) certificate, which typically costs $25 to $150 depending on your state and county.

Step 2: Prepare and File Your Articles of Organization

The Articles of Organization is the official document that legally establishes your LLC. This is filed with your state’s Secretary of State office and is the most critical step in the formation process.

Most states provide a standard form on their Secretary of State website, often available as a downloadable PDF or fillable online form. Your Articles of Organization must include your LLC’s legal name, the state where it’s organized, the address of your principal place of business, and the name and address of your registered agent (the person or company authorized to receive legal documents on behalf of your LLC).

Filing fees vary dramatically by state. Wyoming, New Mexico, and Montana charge under $100, while states like California charge $70 for initial filing plus potential additional fees, and New York charges $25 for online filing or $125 for expedited service. Many states charge between $100 and $300. You can file online in most states, and processing times range from same-day approval to 5 to 7 business days depending on whether you pay for expedited processing.

Step 3: Obtain an EIN and Open a Business Bank Account

An Employer Identification Number (EIN), also called a Federal Tax ID, is issued by the Internal Revenue Service (IRS) and is required if your LLC has employees or is taxed as a partnership or corporation. Even if it’s not required, obtaining an EIN is free and recommended because it separates your personal finances from your business finances.

You can apply for an EIN online at the IRS website in minutes, by phone, by fax, or by mail. Online applications are processed immediately and you receive your EIN right away. This step costs nothing and takes less than 15 minutes.

Once you have your EIN, open a dedicated business bank account. Mixing personal and business funds is one of the biggest mistakes LLC owners make—it can jeopardize your liability protection if your business is sued. You’ll need your Articles of Organization, EIN letter, and government-issued ID to open the account. Many banks offer free or low-cost business checking accounts, though some charge monthly fees of $10 to $25.

Step 4: Create an Operating Agreement

An Operating Agreement is an internal document that outlines how your LLC will be managed, including member roles, profit distribution, decision-making processes, and what happens if a member wants to leave or passes away. While most states don’t legally require an Operating Agreement for single-member LLCs, it’s strongly recommended because it demonstrates that you treat your LLC as a separate legal entity—critical for protecting your personal assets.

You can draft an Operating Agreement yourself using templates (typically $10 to $50), hire a business attorney ($500 to $2,000 for a custom agreement), or use online legal services like LegalZoom or Rocket Lawyer ($100 to $300). For a basic single-member LLC, a template is usually sufficient. For multi-member LLCs, an attorney review is worth the investment.

Step 5: Understand Ongoing Compliance Requirements

Forming your LLC is just the beginning. Most states require annual reports, renewals, and franchise tax payments to keep your LLC in good standing. These ongoing costs add up over time and vary significantly by state.

Annual reports (also called renewals) typically cost $25 to $150 per year, though some states like California charge franchise taxes of $800 per year regardless of revenue. Failing to file an annual report or pay required fees can result in administrative dissolution, meaning your LLC loses its legal status and your liability protection disappears.

Additionally, you’ll need to register for state and local taxes (sales tax, income tax, employment taxes if applicable) and obtain any licenses or permits specific to your industry. These costs vary widely by business type and location but can range from $0 to $1,000 or more annually.

Frequently Asked Questions

What is the average cost to form an LLC across all 50 states?

The average LLC formation cost ranges from $150 to $500 when combining filing fees, registered agent fees, and basic legal documents. However, the total includes significant variation—Wyoming might cost under $150, while California or New York could exceed $800 in the first year due to franchise taxes and processing fees.

How long does it take to form an LLC?

LLC formation typically takes 5 to 10 business days for standard processing in most states, though online filing in states like Delaware or Nevada can be approved within 24 hours. Expedited processing is available in many states for an additional $50 to $100 and can reduce processing time to 1 to 3 days.

Do I need a registered agent to form an LLC?

Yes, every LLC must have a registered agent listed in the Articles of Organization. This can be you (at your business address), a business partner, or a professional registered agent service that costs $50 to $300 annually. The registered agent is the person authorized to receive legal and tax documents on behalf of your LLC.

Can I form an LLC myself without hiring a lawyer?

Absolutely. Most entrepreneurs file their own Articles of Organization using state-provided forms or affordable online services costing $10 to $100. You don’t need a lawyer to form an LLC, though one can be helpful for complex situations like multi-member LLCs or businesses with significant liability concerns.

What’s the difference between LLC formation costs and ongoing compliance costs?

Formation costs are one-time expenses paid when you establish your LLC, typically $100 to $500. Ongoing costs are annual or recurring fees like registered agent fees ($50 to $300 per year), annual reports ($25 to $150 per year), franchise taxes, and business licenses—totaling $100 to $1,000+ annually depending on your state and industry.
