In recent years, as the global business environment continues to evolve, more and more Chinese entrepreneurs and small-to-medium enterprise SME owners have turned their attention to overseas markets-especially the United States, the world’s largest economy. The U.S. not only boasts a mature legal framework for business but also offers a highly open market environment, making it an attractive destination for companies seeking international expansion.

According to data released by the U.S. Department of Commerce in 2025, the number of new business registrations in the U.S. has continued to rise, with Asian-based company registrations increasing by more than 15% year-on-year. This trend reflects the growing interest from Asian countries, including China, in the U.S. market. For many entrepreneurs, successfully registering a company in the U.S. has become the first step toward global expansion.

This article provides a detailed overview of the essential business registration documents required to set up a company in the U.S., helping you navigate the process, avoid risks, and take your first confident step toward internationalization.

1. Basic Types of U.S. Companies and How to Choose

Before registering a company in the U.S., it's crucial to determine the appropriate business structure. Different types of companies involve distinct registration procedures, tax implications, and legal responsibilities. The most common business structures include

Limited Liability Company LLC One of the most popular choices, offering flexibility and legal protection, ideal for small and medium-sized businesses.

Corporation Suitable for companies planning to raise capital or go public, divided into C Corporations and S Corporations.

Partnership Applicable for businesses jointly owned and operated by two or more individuals.

Sole Proprietorship The simplest structure, but the owner bears unlimited personal liability.

According to statistics from the U.S. Small Business Administration SBA, around 70% of new businesses registered in 2025 chose the LLC structure due to its advantages in liability protection and tax flexibility.

2. Key Business Registration Documents Required in the U.S.

Although registration procedures may vary slightly by state, the core documents remain largely consistent. Below is a general checklist of essential documents for U.S. company registration

1. Business Name Registration Application

Before registration, you must ensure that the company name is unique. You can check name availability through the official website of the state. Some states require a Name Reservation application to prevent the name from being taken during the registration process.

2. Articles of Organization or Articles of Incorporation

This is a core document required for company registration, submitted to the Secretary of State in the state of registration. It typically includes the company name, address, business purpose, and registered agent information. For LLCs, this document is called the Articles of Organization; for corporations, it's known as the Articles of Incorporation.

3. Operating Agreement

Although not required in all states, an Operating Agreement is critical for internal governance. It outlines the rights and responsibilities of members or shareholders, profit distribution, and management structure. For LLCs, this document helps prevent internal disputes.

4. Registered Agent Information

U.S. law requires every registered company to appoint a Registered Agent, who is responsible for receiving legal and tax documents. The agent can be an individual or a professional service, and must have a physical address in the state of registration.

5. Employer Identification Number EIN Application

Issued by the Internal Revenue Service IRS, the EIN functions like a Social Security Number for a business. It is required for tax filings, opening bank accounts, and other business activities. Foreign businesses can apply online for an EIN without needing a U.S. Social Security Number.

6. Business License

Depending on the location and industry, businesses may need to obtain specific licenses. For example, food service or healthcare businesses require industry-specific permits. Local cities or counties may also require general business licenses.

7. Tax Registration and State Tax Filings

After company registration, businesses must register for state taxes based on their business activities, such as sales tax or employer tax. For example, California requires businesses to apply for a Sales Tax Permit with the California Department of Tax and Fee Administration CDTFA within 30 days of registration.

3. Overview of the Registration Process

1. Choose a Business Type and State of Registration Popular states include Delaware, California, and Nevada, known for their business-friendly environments.

2. Conduct a Name Search and Reserve the Name if required.

3. Prepare and Submit the Articles of Organization or Incorporation and Other Required Documents.

4. Appoint a Registered Agent.

5. Apply for an EIN from the IRS.

6. Obtain Business Licenses and Complete Tax Registrations.

7. Open a U.S. Bank Account if needed.

The entire process typically takes 2-4 weeks, depending on the state’s processing speed. For foreign businesses, it is highly recommended to engage a professional attorney or registration agency to ensure full compliance.

4. Important Notes and Common Mistakes

Choosing the Right State is Critical Tax policies and legal environments vary significantly by state. Delaware is known for its well-developed corporate law, while California has stricter regulatory requirements.

Registered Address Must Be Valid Many entrepreneurs use virtual or personal addresses, but using an invalid address can result in the revocation of the company.

EIN Application Requires Accurate Information Errors in the application can cause problems with tax filings and bank account openings.

Don’t Ignore Annual Reporting and Compliance Requirements Most states require companies to file annual reports and pay annual fees. Failure to comply may result in fines or automatic dissolution.

5. Conclusion

As more Chinese companies pursue international growth, the U.S. market has become a strategic priority. Understanding the basic procedures and essential documents for U.S. company registration is the first step toward a successful market entry.

Whether choosing an LLC or a Corporation, selecting the right business structure, submitting accurate documents, and complying with local laws are all essential steps. For entrepreneurs aiming to expand overseas, careful planning and professional support can significantly improve registration efficiency, reduce legal risks, and lay a solid foundation for global business development.
