According to recent data released by the U.S. Department of Commerce, the number of newly registered businesses in the first quarter of 2025 increased by more than 12% year-on-year, demonstrating the continued attractiveness of the U.S. business environment.

For foreign investors planning to operate in the U.S., understanding the corporate legal system and registration procedures is the first step toward success.

I. Overview of U.S. Corporate Legal Structures

The U.S. corporate legal system is relatively flexible and primarily includes several common business structures Limited Liability Company LLC, Corporation, Partnership, and Sole Proprietorship.

Among these, LLC and Corporation are the most popular choices for foreign investors. LLCs are favored by many startups and SMEs due to their limited liability, flexible tax treatment, and simple management structure. Corporations, on the other hand, are more suitable for companies planning to raise capital, go public, or expand significantly.

The U.S. legal system allows foreigners to serve as shareholders, directors, or executives of a company without requiring U.S. citizenship or a green card-offering great convenience to international entrepreneurs.

It's important to note that U.S. state laws vary, and company registration is typically handled at the state level. Choosing the right state for registration is therefore a critical decision. For example, Delaware is one of the most popular states for incorporation due to its mature legal framework and business-friendly policies.

II. Basic Steps to Register a U.S. Company

1. Determine Company Type and State of Registration

Before registration, it’s essential to choose the appropriate business structure and state based on your operational needs. LLC and Corporation are the most common choices, with Delaware, California, and New York being popular registration states due to their strong legal systems and favorable business climates.

2. Choose a Company Name and Conduct a Name Search

The company name must comply with the relevant state laws and must not duplicate any existing registered company names. Most states provide online name search tools, allowing applicants to verify availability before submitting an application.

3. Appoint a Registered Agent

Every company registered in the U.S. must appoint a Registered Agent, who is responsible for receiving legal documents and official notices. The agent must be either a resident of the state or a licensed service provider.

4. Submit Registration Documents and Pay Fees

After confirming the company name and selecting a registered agent, the next step is to file the necessary documents with the state government-such as Articles of Organization for LLCs or Articles of Incorporation for Corporations. These documents typically include the company name, registered address, agent information, and business purpose. Submissions can be made online or by mail, with fees ranging from $100 to $300 depending on the state.

5. Obtain an Employer Identification Number EIN

The EIN is a unique identification number assigned by the Internal Revenue Service IRS to businesses, similar to a Social Security number for individuals. Even if a company has no employees, it is recommended to obtain an EIN to facilitate opening a bank account, applying for business licenses, and fulfilling tax obligations.

6. Apply for Business Licenses and Tax Registration

Depending on the state and local regulations, businesses may need to apply for a Business License and complete tax registrations, including state and sales tax. If the company plans to hire employees, it must also register for federal and state employer tax accounts.

7. Open a Corporate Bank Account

After registration, it is advisable to open a U.S. corporate bank account to manage daily financial operations. Some banks allow remote account opening, but typically require documents such as the EIN and corporate bylaws.

Tax Compliance

U.S. companies must comply with both federal and state tax regulations.

It is advisable to consult a professional accountant or tax advisor to ensure full compliance.

Annual Reporting and Renewal Fees

Most states require annual reports and renewal fees. Failure to submit on time may result in penalties or the revocation of the company's legal status.

Intellectual Property Protection

If the company involves branding or trademarks, it is recommended to register with the United States Patent and Trademark Office USPTO to protect intellectual property rights.

Businesses must comply with U.S. laws and regulations in areas such as contract signing, employment, and consumer protection to avoid legal disputes.
