How to Register a Company in the United States A Step-by-Step Guide to U.S. Business Registration

Establishing a company in the United States does not require the founder to be physically present in the U.S., nor is it mandatory to engage a local attorney for end-to-end oversight. As long as one thoroughly understands the applicable rules and selects the appropriate pathway, a single individual can complete the entire registration process within just a few days. In practice, most entrepreneurs are less concerned with whether registration is possible-and more focused on how to register without encountering pitfalls significant variations among state laws, ambiguity surrounding tax classification, and easy-to-overlook post-registration compliance obligations-these are the real challenges.

How to Register a Company in the United States?

The core steps involve selecting a state, choosing an entity type, and executing the procedural requirements.

Company registration, in essence, consists of filing legally mandated documents with the relevant state agency to obtain formal legal entity status. There is currently no federal-level “nationwide unified company registration” in the U.S.; all registration authority resides solely at the state level. Delaware and Wyoming remain the most frequently chosen states Delaware benefits from a mature body of case law and is widely favored by publicly traded companies; Wyoming is renowned for its strong privacy protections and absence of state corporate income tax.

Beginning in 2025, stricter Beneficial Ownership Information (BOI) reporting requirements will take effect in states including New York and California. All newly formed entities must file a BOI report via the Financial Crimes Enforcement Network (FinCEN) system. Failure to comply may result in penalties of up to $500 per day-this is now a mandatory requirement, not optional.

Key Steps in U.S. Company Registration - Clearly Broken Down

1. Determine Your Business Structure

Limited Liability Companies (LLCs) account for over 80% of newly formed businesses due to their simplicity and clear liability separation. C-Corporations (C-Corps) are better suited for teams planning to raise venture capital or pursue an IPO. S-Corporations (S-Corps) offer pass-through taxation but impose strict eligibility criteria-including limitations on shareholder nationality and number-making them more complex to qualify for.

2. Verify and Register Your Business Name

Conduct a name availability search via the target state’s Secretary of State website. The chosen name must include a legally required suffix (e.g., “LLC,” “Inc.”) and must not conflict with any existing registered entity.

3. Appoint a Registered Agent

A registered agent must maintain a physical street address within the state of formation and serve as the official point of contact for receiving legal documents (e.g., service of process). Virtual email addresses or overseas mailing addresses are not acceptable substitutes.

4. File the Certificate of Organization (for LLCs) or Articles of Incorporation (for Corporations)

Online filing is standard. In Delaware, approval typically occurs within approximately one hour; in Wyoming, processing usually takes 1-3 business days. Filing fees generally range between $100 and $300, depending on the state and optional expedited services.

5. Obtain an Employer Identification Number (EIN)

Apply free of charge through the IRS website. A Social Security Number (SSN) is not required. Foreign applicants may complete Form SS-4 and complete identity verification via telephone interview. EINs are typically issued within 3-5 business days.

U.S. Business Registration Required Documents and Post-Registration Actions - None Are Optional

1. Operating Agreement (for LLCs)

While not statutorily mandated in most states, an Operating Agreement is indispensable-for opening a bank account, defining equity distribution, and clarifying member rights and responsibilities. It should be formally executed and retained securely.

2. Beneficial Ownership Information (BOI) Reporting

For entities formed on or after January 1, 2025, FinCEN Form 8362 must be filed within 30 calendar days of formation. This requires disclosure of each beneficial owner’s full name, date of birth, identifying document (e.g., passport or driver’s license), and current residential address.

3. State Tax Registration

If engaging in retail sales, you must apply for a Sales Tax Permit from the relevant state’s Department of Revenue. If hiring employees, you must also register separately for state unemployment insurance and state income tax withholding accounts.

4. Open a U.S. Business Bank Account

Many U.S. banks permit remote video notarization for foreign directors. Required documentation typically includes the Certificate of Formation/Organization, the IRS-issued EIN confirmation letter, the Operating Agreement (or Bylaws), and the director’s valid passport. However, certain traditional banks-such as JPMorgan Chase and Bank of America-still prefer in-person visits. For international founders, digital-first banks like Mercury and Novo-which explicitly support non-resident clients-are often more practical starting points.

Important Reminder Completing registration does not mean your company is fully operational or compliant. For example

If an LLC fails to file its Annual Report on time, Delaware imposes a $200 late fee and suspends the company’s “Good Standing” status.

California levies an $800 annual franchise tax on all LLCs-waived only for the first year, then charged beginning in Year 2.

Additionally, as of 2025, numerous states-including Arizona and Florida-have upgraded to fully electronic filing systems. These states now require Annual Reports to be submitted online and paid via credit card; paper filings and mailed checks are no longer accepted.

The above outlines the current, practical essentials for registering a U.S. company across leading states. We hope this guide proves helpful to you.
