Registering a Company in the United States Key Certificates and Documents to Consider

Registering a company in the United States is an important step for many entrepreneurs and business owners aiming to achieve their commercial objectives. With the deepening of global economic integration, more and more international investors are setting their sights on the U.S. market. However, as a federal country, the U.S. has varying company registration requirements across its states. Therefore, understanding the necessary certificates and documents before registration is particularly important.

The U.S. does not have a unified national process for company registration-each state governs its own procedures. This means that the choice of state for registration will directly affect the required documents and certificates. For example, Delaware is a popular choice for incorporation due to its business-friendly environment and well-developed corporate legal framework. According to a 2025 business report, over 60% of publicly traded companies in the U.S. are registered in Delaware, a statistic closely tied to its flexible legal structure and favorable tax policies.

Regardless of the chosen state, the following categories of certificates and documents are typically essential

1. Company Name Application and Availability Search

Before registering a company, it is necessary to confirm that the desired name is available in the target state. This is usually done via an online search on the Secretary of State’s official website. It is also important to ensure that the name does not infringe on existing trademarks, so as to avoid potential legal disputes in the future.

2. Articles of Incorporation or Certificate of Formation

This is one of the core documents required for company registration. It typically includes the company’s name, registered address, business purpose, share structure for corporations, and information about the Registered Agent. While specific requirements may vary slightly by state, the overall structure is similar. For instance, California requires the filing of Articles of Incorporation, while Texas uses a Certificate of Formation.

3. Registered Agent Registered Agent

Almost all states require a company to appoint a Registered Agent at the time of registration. The agent’s role is to receive legal documents and official notices on behalf of the company and ensure timely responses. The Registered Agent must be a resident of the state or a corporation authorized to do business in that state. Many companies opt for professional Registered Agent services to fulfill this requirement.

4. Federal Tax ID EIN - Employer Identification Number

Similar to China’s Unified Social Credit Code, the EIN is a unique identification number assigned by the Internal Revenue Service IRS for tax reporting and opening a business bank account. Even companies without employees are required to obtain an EIN. According to the IRS website, foreign businesses registering in the U.S. can apply for an EIN online or by completing Form SS-4.

5. Operating Agreement for Limited Liability Companies - LLCs

While not mandatory in all states, it is highly advisable for LLCs to have a detailed Operating Agreement. This document outlines the rights and responsibilities of members, profit distribution methods, and management structure, helping to prevent potential internal disputes.

6. State Business License and Industry Permits

After completing company registration, it is also necessary to apply for a Business License in accordance with local state and city regulations. If the company operates in a regulated industry such as healthcare, finance, or food services, additional industry-specific licenses may be required. For example, in 2025, California introduced stricter regulations for tech startups, requiring certain AI development companies to submit data privacy protection plans to meet new compliance standards.

7. Annual Reports and Renewal Documents

Most states require companies to file an Annual Report every year or every two years and pay the associated fees. This is a critical step in maintaining the company’s legal standing. Failure to submit reports on time may result in fines or even involuntary dissolution of the company. For instance, in 2025, Florida updated its Annual Report submission system, requiring all companies to file online to improve efficiency and transparency.

For foreign investors, the following additional considerations are important

Choice of Jurisdiction In addition to Delaware, states like Wyoming and Nevada are also popular among international investors due to their favorable tax policies and strong privacy protections.

Visa and Immigration Issues Registering a U.S. company does not automatically grant the owner the right to live or work in the U.S. Those planning to operate in the U.S. long-term may need to apply for appropriate business visas, such as the E-2 Treaty Investor Visa or the L-1 Intracompany Transferee Visa.

Bank Account and Financial Management After registration, companies typically need to open a U.S. business bank account. In recent years, U.S. financial institutions have imposed stricter requirements for anti-money laundering AML and know-your-customer KYC compliance. Therefore, adequate identification and company documents must be prepared when opening an account.

In summary, while the process of registering a company in the U.S. is relatively standardized, it involves a wide variety of certificates and documents, with differing requirements across states. It is advisable to conduct thorough research or consult with professional legal and business advisors before registration to ensure full compliance. Additionally, staying informed about recent changes in state registration policies will help mitigate potential risks and lay a solid foundation for long-term business growth.
