Formation: US LLC Formation Process Definition

What is LLC formation? Learn the step-by-step process to legally form a US LLC including state selection, registered agent appointment, and EIN application.

Definition

Formation refers to the legal process of establishing a Limited Liability Company (LLC) under US state law. This involves filing formation documents with the Secretary of State and satisfying state-specific requirements.

Unlike simply registering a business name, formation creates a legally recognized entity with liability protection and the ability to enter contracts, open bank accounts, and conduct business.

The Formation Process Step by Step

Step 1: Choose Your State

The state where you form your LLC determines:

  • Filing fees and ongoing costs
  • Privacy protections
  • Legal framework (Delaware has the most developed business case law)
  • Tax treatment
StateFiling FeeAnnual FeeBest For
Delaware$90$300Corporate law, investor readiness
Wyoming$100$60Privacy, low cost, simple requirements
New Mexico$100$0Very low cost
California$70$800If you have physical presence in CA

Important: You do not need to form your LLC in the state where you physically operate. Many non-US founders form in Delaware or Wyoming but operate from their home country.

Step 2: Choose a Registered Agent

Every state requires an LLC to have a registered agent with a physical address in the formation state. The registered agent receives:

  • Legal summons and lawsuits
  • Tax notices from state agencies
  • Official government correspondence

You cannot use a P.O. Box or your personal address as a registered agent.

Step 3: File Articles of Organization

This is the primary formation document submitted to the state. It typically requires:

  • LLC name (must include LLC or Limited Liability Company)
  • Registered agent name and address
  • Principal office address (can be anywhere)
  • Management structure (member-managed or manager-managed)
  • Duration (perpetual or specific end date)

Filing fees range from $50 to $500 depending on the state.

Step 4: Create an Operating Agreement

Although not required in most states, an operating agreement is essential for:

  • Defining ownership percentages
  • Outlining profit distribution
  • Establishing management roles
  • Preventing disputes between members

For single-member LLCs, an operating agreement helps demonstrate that the LLC is a separate entity from the owner.

Step 5: Obtain an EIN

The Employer Identification Number (EIN) is required for:

  • Opening US bank accounts
  • Filing taxes
  • Hiring employees (if applicable)

Apply via IRS Form SS-4. Non-US founders can fax the form to IRS to receive an EIN without a US phone number.

Foreign-Owned LLC Formation Considerations

Non-US founders face unique considerations during formation:

  1. No US presence required — You can form and operate an LLC entirely from overseas
  2. ITIN not required for formation — EIN is the critical number, not ITIN
  3. Registered agent required — This is the only mandatory US connection
  4. State selection matters — Delaware and Wyoming offer the best combination of low cost and strong legal protections
  • LLC: The legal entity you are forming
  • Registered Agent: The mandatory US-based representative for your LLC
  • EIN: The tax ID required after formation
