Everything You Need to Know About the Document Checklist for Registering a U.S. Company

To register a company in the United States is not merely a matter of filling out a form and paying a fee. In practice, whether supporting documents are complete and whether information is entered in compliance with regulations directly determines whether registration will be approved on the first submission. Requirements vary by state; however, the core framework of required documents remains largely consistent-the critical factors are factual accuracy and logical consistency.

Documents Required to Register a U.S. Company

1. Company Name Must comply with the naming rules of the state of registration-typically requiring a statutory suffix such as “Corp,” “Inc.,” or “LLC”-and must not duplicate the name of any existing active entity. It is advisable to conduct a name availability search in advance via the Secretary of State’s official website.

2. Registered Agent Information Must be an individual or service provider with a physical street address located within the United States, responsible for receiving legal documents on behalf of the company. This address will be publicly listed in the state’s official database and cannot be a virtual email address or a P.O. Box.

3. Company Registered Address May be identical to the registered agent’s address. However, if it serves as the company’s actual business address, it must be capable of receiving official correspondence from platforms or government agencies. While some states accept commercial addresses, using a residential address as the sole registered address is strictly prohibited (e.g., California explicitly restricts this).

4. Corporate Governance Documents For an LLC, an Operating Agreement must be prepared (though not required for filing with the state, it is essential for bank account opening and internal governance). For a corporation (C-Corp or S-Corp), Bylaws and the minutes of the initial Board of Directors meeting must be drafted.

5. Shareholder/Member Identification Documents Non-U.S. residents must provide a scanned copy of the passport information page. If ownership is held through another company, the parent company’s Certificate of Good Standing and a certified copy of its Articles of Incorporation (or equivalent organizational documents) must also be submitted.

Key Supplemental Documents for U.S. Company Registration

6. EIN (Employer Identification Number) Application Apply online with the IRS. Required information includes company type, state of formation, and the responsible individual’s Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). Foreign applicants without an SSN or ITIN may apply by mailing Form SS-4 together with a signed explanatory letter.

7. Documents Required for Bank Account Opening In addition to the EIN confirmation letter, most banks also require a certified copy of the Articles of Organization (for LLCs) or Articles of Incorporation (for corporations), a Certificate of Incumbency signed by the registered agent, and a Beneficial Ownership Information (BOI) declaration confirming compliance with the FinCEN BOI reporting requirement.

8. State Tax Registration For example, California requires submission of Form 3522 to apply for the first-year franchise tax exemption; New York State mandates concurrent registration for a sales tax permit if the company sells taxable goods or services.

Important Notice

All documents submitted to the Secretary of State’s office must bear either a handwritten electronic signature or an original wet-ink signature. PDF scan copies where the signature is not clearly legible may be rejected. While certain states (e.g., Delaware) permit third-party agents to file documents on behalf of the applicant, the signatory remains legally responsible for the accuracy and truthfulness of all information contained therein.

The above outlines the core documentation required to register a company in the United States. Should you have related questions-or wish to learn more about state-specific differences, tax compliance requirements, or subsequent annual report filing procedures-we recommend consulting a licensed U.S. attorney or a certified public accountant with cross-border corporate services experience, taking into account your company’s specific operational location and business model.
