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

Starting a limited liability company (LLC) is one of the most popular business structures for entrepreneurs, freelancers, and small business owners. Unlike a sole proprietorship, an LLC provides personal asset protection while offering simpler tax treatment than a corporation. However, the process, timeline, and costs vary significantly depending on your state. This guide walks you through every step of forming an LLC and shows you exactly what to expect in all 50 states.

Why Choose an LLC Structure?

Before diving into the mechanics, it’s worth understanding why LLCs have become America’s preferred business entity. An LLC separates your personal assets from business liabilities, meaning creditors generally cannot come after your home or personal bank accounts if your business faces legal trouble. This liability protection is the primary reason entrepreneurs choose LLCs over sole proprietorships.

LLCs also offer flexible taxation. By default, a single-member LLC is taxed as a sole proprietorship, while multi-member LLCs are taxed as partnerships. You can elect to be taxed as an S-Corporation, which may save you thousands in self-employment taxes if your LLC is profitable. Unlike corporations, LLCs avoid the double taxation problem where profits are taxed at both the business and personal level.

Setup costs are typically lower for LLCs than corporations, with filing fees ranging from $40 in Wyoming to $500 in California. Most states fall between $100 and $300 for the basic filing.

The 7-Step Process to Start Your LLC

Step 1: Choose Your LLC Name — Your business name must be unique within your state and typically must include “LLC” or “Limited Liability Company.” Check your state’s Secretary of State database to verify availability. Some states allow name reservation for $10 to $30 for 30 to 120 days, giving you time to complete other setup tasks.

Step 2: File Articles of Organization — This is the core document that legally establishes your LLC. You’ll file it with your state’s Secretary of State office along with the required filing fee. Most states accept online filing, which typically processes within 5 to 10 business days. Expedited processing is available in many states for an additional $25 to $150 fee.

Step 3: Obtain an EIN — The IRS issues an Employer Identification Number free of charge, even if you’re a solo LLC with no employees. You can apply online at irs.gov or by mail; online approval is typically instant. You’ll need your EIN to open a business bank account and file taxes.

Step 4: Create an Operating Agreement — While not legally required in most states, an operating agreement is strongly recommended. It documents how your LLC will be managed, how profits and losses are distributed, and member rights and responsibilities. A basic operating agreement costs $0 to $200 if you use templates; attorney-drafted versions run $300 to $1,000.

Step 5: Register for State Taxes — Depending on your state and business type, you may need sales tax permits, payroll tax accounts, or other registrations. Your state’s Department of Revenue website lists specific requirements.

Step 6: Obtain Business Licenses and Permits — Local governments and professional licensing boards may require specific permits for your industry. A general business license costs $50 to $400 annually, while specialized licenses vary widely.

Step 7: Open a Business Bank Account — Bring your EIN letter and Articles of Organization to a bank. This separates business and personal finances and simplifies tax preparation and accounting. Many banks offer no-fee business checking for the first year.

LLC Formation Costs by State

Formation costs vary dramatically across the 50 states. Wyoming, Nevada, and South Dakota are popular for their low fees and business-friendly laws. Wyoming charges just $40 to $100 for Articles of Organization, while Nevada charges $75 to $150. However, you must maintain registered agent services in these states, typically costing $50 to $300 annually.

Mid-range states like Texas ($300), Florida ($125), and Ohio ($99) offer reasonable costs with moderate regulations. High-cost states include California ($70 to $120 for filing, but with mandatory annual report fees of $800 even if you earn no income), New York ($25 to $200 for filing), and Massachusetts ($500).

The true cost of forming an LLC extends beyond state filing fees. Factor in registered agent services ($50 to $300 per year), business license fees ($50 to $400 annually), operating agreement creation ($0 to $1,000), and legal consultation ($0 if DIY, $500 to $2,000 for attorney guidance). Most entrepreneurs spend $200 to $800 total in year one, excluding industry-specific licenses.

How Long Does LLC Formation Take?

Standard processing times range from same-day to 10 business days, depending on your state and whether you pay for expedited service. Delaware typically processes filings within 1 to 2 business days without expediting, while California takes 5 to 10 days for standard processing. Wyoming and Nevada offer same-day service for an extra $100 to $150.

The total timeline from beginning to finish usually spans 2 to 6 weeks once you account for EIN issuance (instant to one week), bank account opening (3 to 5 business days), and obtaining specialized licenses (varies widely by industry and location).

Common Mistakes to Avoid

Many new LLC owners make costly errors during formation. Skipping the operating agreement leaves you vulnerable to disputes and may allow courts to treat your LLC like a partnership. Mixing personal and business finances defeats the liability protection that LLCs provide—always use separate bank accounts. Failing to maintain ongoing compliance, such as annual reports and registered agent fees, can result in loss of LLC status in some states.

Another mistake is choosing the wrong state. While forming in Delaware or Nevada might seem attractive, you must still register as a foreign LLC in your home state, doubling your costs. Most entrepreneurs should form their LLC in their home state unless they operate primarily in another state or need specific legal advantages.

Finally, not consulting tax professionals about entity selection can be expensive. An S-Corp election might save you more than the cost of consulting a CPA, especially if your LLC is highly profitable.

Frequently Asked Questions

What’s the cheapest state to form an LLC?

Wyoming is typically the most affordable at $40 to $100 for Articles of Organization filing. However, you’ll need a registered agent service costing $50 to $300 annually, which adds up if you’re not based there. For most people, forming in their home state is more economical overall, even if the initial filing is slightly higher.

Do I need a lawyer to start an LLC?

No, you can file your own LLC using online services or state templates, saving $500 to $2,000 on legal fees. However, an attorney is valuable if you have complex ownership structures, need an ironclad operating agreement, or operate in highly regulated industries. Many entrepreneurs use DIY filing for the Articles of Organization and consult a lawyer only for the operating agreement.

Can I change my LLC’s name after formation?

Yes, most states allow name amendments by filing an Articles of Amendment with the Secretary of State for $25 to $150. However, you’ll need to update your EIN registration, business licenses, and all legal documents, so it’s worth getting the name right initially.

How often do I need to renew my LLC?

Most states require annual or biennial renewal with filing fees ranging from $0 to $800 (California’s annual report is notably expensive at $800 plus). Some states like New York require biennial renewals every two years. Check your state’s specific requirements to avoid losing LLC status.

Is there a difference between forming an LLC and getting a business license?

Yes, they’re separate. Forming an LLC creates your legal business entity and requires state filing. A business license is typically a local or state permit allowing you to operate a specific type of business. You need both for full compliance, though some industries skip the formal LLC and operate as sole proprietorships.

Conclusion

Starting an LLC is straightforward when you follow a clear roadmap. By understanding your state’s specific requirements, timeline, and costs, you can avoid surprises and protect your personal assets from day one. The entire process typically costs $200 to $800 in year one and takes 2 to 6 weeks from start to finish. Whether you’re launching a side hustle or a full-scale business, forming an LLC sends a professional signal to customers, lenders, and partners while giving you the liability protection entrepreneurs need.
