Complete LLC Formation Checklist

Choosing the correct state is the most critical first step. Where you form your LLC dictates your filing fees, annual report costs, state tax burdens, and corporate privacy rules.

Your LLC name must be completely distinguishable from any other active business entity currently registered in your chosen state. It must also comply with legal requirements.

Core Checklist Actions:

• Add an LLC Designator: Your business name must end with an official designator like "LLC", "L.L.C.", "Limited Liability Company", or "Ltd. Liability Co."
• Search the State Registry: Run an official name search on your state's Secretary of State or Department of Commerce online business registry.
• Avoid Restricted Words: Words like "Bank", "University", "Insurance", "Trust", or "Doctor" require special licenses and approvals.
• Secure the Domain & Socials: Before filing, ensure your matching .com domain name is available and secure corresponding usernames on LinkedIn, Twitter/X, and Instagram.

Every single US state legally requires your LLC to designate a Registered Agent. The registered agent is your company's official point of contact for service of process (lawsuits) and state renewal notices.

Key Requirements:

• Must have a physical street address within the state of formation (P.O. boxes are strictly prohibited).
• Must be available at that physical address during normal business hours (9:00 AM to 5:00 PM, Monday through Friday).

Filing the Articles of Organization (sometimes called a "Certificate of Organization" or "Certificate of Formation" depending on the state) is the official administrative act that legally births your LLC.

What You Need to Disclose:

• LLC Name: The exact approved name, including your LLC designator.
• Registered Agent: The name and physical address of your appointed agent.
• Management Structure: Choose whether the LLC will be Member-Managed (run directly by all owners) or Manager-Managed (run by designated managers or officers).
• Mailing Address: Where the state should send renewal notices and tax information.

The Employer Identification Number (EIN) is a nine-digit number issued by the Internal Revenue Service (IRS). Think of it as a Social Security Number for your business entity.

Why an EIN is Mandatory:

• Opening a US business bank account.
• Hiring employees or contractors legally.
• Filing federal and state corporate tax returns.
• Establishing merchant payment processors (Stripe, PayPal, Shopify Payments).

An Operating Agreement is a legal contract that details the internal operating rules, ownership distribution, capital contributions, voting rights, and dissolution procedures of your LLC.

Why You Need One (Even if You Are a Solo Founder):

• Protects Personal Liability: It legally separates your personal actions from your business, proving to courts that your LLC is a legitimate, separate legal entity (preventing "piercing the corporate veil").
• Required by Banks: Almost all commercial banks require a signed Operating Agreement before they will open your business bank account.
• Prevents Partner Disputes: For multi-member LLCs, it pre-determines how profits are distributed, how members can exit, and how management decisions are finalized.

Mixing personal funds with business funds is the #1 mistake LLC owners make. This error, known as "commingling," completely invalidates your limited liability protection in the eyes of a judge.

What to Bring to open an Account:

• Approved Articles of Organization / Certificate of Formation.
• IRS EIN Confirmation Letter (CP 575 or 147C).
• Signed LLC Operating Agreement.
• Valid government-issued photo ID (Passport or Driver's License).

Registering your LLC is just the beginning. To keep your liability shield strong and avoid state dissolution or severe federal fines, you must meet regular maintenance deadlines.

Mandatory Annual Compliance Checklist:

• State Annual Report & Franchise Tax: Most states require a yearly renewal filing. Wyoming charges $60 annually, Delaware charges $300, and California charges a mandatory $800 annual franchise tax.
• Federal BOI Report (FinCEN): Under the Corporate Transparency Act, all LLCs must file a Beneficial Ownership Information report with FinCEN. LLCs formed in 2026 have 30 days to file from formation. Failure to file can result in severe civil penalties.
• IRS Tax Filings: Single-member LLCs are "disregarded entities" by default. Non-US residents must file Form 5472 and Form 1120 annually, even with zero US-sourced income, to report transactions with their LLC.
