How Easy Is It to Start a Company in the U.S.? A Step-by-Step Guide to Registering a U.S. Company, Establishing a U.S. Subsidiary, and Completing the Entire New Registration Process

Establishing a company in the U.S. is often mistakenly believed to require complex procedures or U.S. residency-yet the process is in fact transparent, with clearly defined thresholds, and most states allow non-residents to complete the entire registration remotely. The key lies in selecting the appropriate state of incorporation, understanding tax obligations, and choosing the right corporate structure-not in relying on intermediaries’ marketing language.

I. Three Critical Considerations Before Registration

1. Choose the corporate entity type based on your actual business needs: A Limited Liability Company (LLC) suits most small- and medium-sized operations, while a Corporation (Inc.) is better suited for businesses planning to raise capital or pursue an IPO.

2. Do not select a state of incorporation solely based on cost or popularity: Delaware offers a mature legal framework but imposes additional fees for foreign qualification; Wyoming levies no state income tax, yet its bank account opening process involves stricter due diligence; Nevada provides strong privacy protections, but its annual reporting requirements are more detailed.

3. The registered agent need not be a U.S. citizen or green card holder-but you must appoint a registered agent who maintains a physical street address within the state of incorporation and is authorized to accept legal documents on the company’s behalf.

II. Core Steps to Register a New U.S. Company

1. Conduct a name availability search and confirm that your chosen company name is unregistered on the target state’s Secretary of State website-and complies with the state’s naming rules (e.g., mandatory use of suffixes such as “LLC” or “Inc.”).

2. Prepare governing documents-either Articles of Organization (for LLCs) or Articles of Incorporation (for Corporations)-specifying member/shareholder information, authorized capital (most states impose no minimum), principal business activities, and management structure.

3. File the formation documents with the state’s Secretary of State office. Some states support instant online filing; others require mailing and may take several days to several weeks for processing.

4. Obtain the official Certificate of Formation (for LLCs) or Articles of Incorporation (for Corporations). This document serves as foundational proof for opening a U.S. bank account and applying for a federal tax ID number.

III. Key Considerations When Establishing a U.S. Subsidiary

1. The parent company must provide a certified Certificate of Good Standing and a certified English translation of its articles of incorporation, both authenticated by a notary public.

2. When registering the subsidiary, the parent company’s official registration number and registered address in its home jurisdiction must be disclosed. Some states further require these documents to be apostilled (under the Hague Convention) or consular-legalized.

3. A U.S. subsidiary does not enjoy automatic exemption from legal liability: while its debts are generally insulated from the parent company’s assets, it remains subject to separate federal and state tax filings and must comply with the state’s annual reporting requirements.

4. For bank account opening, most U.S. banks require the parent company’s director or duly authorized representative to appear in person at a domestic branch. A limited number of banks accept remote video verification-but application materials undergo significantly more rigorous review.

IV. Mandatory Post-Registration Compliance Actions

1. Apply for an Employer Identification Number (EIN) from the U.S. Internal Revenue Service (IRS). This nine-digit number is required for tax filing, payroll reporting, and bank account setup-and the application is free and fully online.

2. Register for a sales tax permit with the relevant state authority if your business sells tangible goods or certain digital services. Sales tax returns must then be filed and remitted periodically per state requirements.

3. File an annual report as mandated by your state of incorporation. Required updates typically include changes to the registered agent’s contact details, principal office address, and confirmation of active corporate status. Late filings incur penalties-and prolonged noncompliance may result in administrative dissolution.

4. Maintain complete financial records for at least six years, including bank statements, invoices, contracts, and expense receipts, to satisfy potential IRS or state tax audits.

The above outlines the foundational pathway and practical considerations for establishing a new U.S. company or a U.S. subsidiary.
