How to Successfully Establish a Company in the United States A Comprehensive Guide and Analysis of Professional Agency Services

In the context of global economic integration, the United States, as one of the world's largest economies, remains a top destination for entrepreneurs and business owners seeking to expand internationally. Whether in tech startups, e-commerce, or traditional manufacturing, more and more entrepreneurs aim to establish companies in the U.S. to access broader markets, a more mature business environment, and stronger brand influence. However, the U.S. legal system, tax structure, and registration procedures differ significantly from those in other countries, making it a challenge for many entrepreneurs to successfully set up a business.

1. Choosing the Right Business Structure

The first step in establishing a company in the U.S. is to determine the appropriate business structure. Common options include

Limited Liability Company LLC This is the most popular choice for foreign investors due to its flexible tax treatment, simple management structure, and limited liability for members.

C Corporation C Corp Suitable for companies planning to raise capital or go public, although it faces double taxation at both the corporate and shareholder levels.

S Corporation S Corp Ideal for small businesses, offering pass-through taxation to avoid double taxation, but with restrictions on the number and nationality of shareholders.

Partnership Best for multiple owners, offering flexible tax treatment, but partners are personally liable for business debts.

Choosing the right structure has a direct impact on tax obligations, legal liability, and future fundraising potential. For example, many tech startups choose to incorporate as C Corporations to attract venture capital investment.

2. Selecting the Right State for Registration

The U.S. is a federal system, and each state has its own laws. Choosing the right state is crucial. Delaware and Nevada are among the most popular due to

Business-Friendly Legal Environment Delaware has a well-developed body of corporate law and a specialized court for commercial disputes.

Tax Advantages Nevada imposes no corporate income tax, capital gains tax, or personal income tax.

Privacy Protection Some states allow anonymous registration, protecting shareholder identities.

However, if a company primarily operates in a particular state, it should register as a domestic corporation in that state; otherwise, additional compliance costs may apply.

3. Registration Process and Required Documents

While the U.S. company registration process is generally standardized, specific steps may vary by state. The typical process includes

1. Company Name Search and Registration Ensure the desired name is available in the chosen state.

2. Filing Articles of Incorporation or Certificate of Formation Submit basic company information to the state.

3. Obtaining an Employer Identification Number EIN This serves as the company’s tax ID for banking and tax purposes.

4. Opening a U.S. Bank Account Some banks allow remote account opening, but typically require an EIN and company documents.

5. Applying for Business Licenses and Industry Permits Depending on the location and business type, additional permits may be required.

In recent years, with the rise of remote work and digital commerce, the U.S. government and financial institutions have gradually relaxed restrictions for foreigners setting up companies remotely. For example, the IRS allows online EIN applications, and some states permit the use of agents to file registration documents.

4. Tax and Compliance Considerations

The U.S. tax system is complex. Foreign companies operating in the U.S. must pay attention to

Federal and State Taxes C Corporations are subject to federal corporate income tax, and some states also impose corporate taxes.

Personal Income Tax If company profits are distributed to shareholders, they may be subject to personal income tax.

Sales Tax If selling physical goods, sales tax must be collected according to the rules of the respective state.

Annual Reporting and Fees Most states require annual reports and renewal fees.

Additionally, the Foreign Account Tax Compliance Act FATCA requires foreign financial institutions to report information about U.S. citizens' accounts to the IRS. Therefore, businesses should consult professional tax advisors early on to plan their tax structure effectively.

5. The Value of Professional Agency Services

For entrepreneurs unfamiliar with U.S. legal and business procedures, working with a professional agency is an efficient and compliant approach. These agencies typically offer

Company Registration and Document Preparation Expertise in state-specific regulations ensures accurate and complete filings.

EIN Application and Bank Account Assistance Support for remote account opening, saving time and effort.

Legal and Tax Advisory Services Help in developing compliance strategies and avoiding potential risks.

Virtual Office and Registered Address Services Provide legal addresses for businesses without a physical presence.

According to media reports in 2025, with the growing trend of Chinese companies expanding overseas, more U.S.-based law and accounting firms have started offering Chinese-language services to assist Chinese entrepreneurs in setting up businesses in the U.S.

6. Case Study A Tech Startup Establishes a Subsidiary in the U.S.

Take a Shenzhen-based AI startup as an example. The company wanted to establish a subsidiary in the U.S. to expand into the North American market. Its setup process included

1. Choosing Delaware as the registration state due to its mature legal system and investor-friendly environment.

2. Using a professional agency to complete the name search, document submission, and EIN application.

3. Opening a U.S. bank account via remote video verification.

4. Hiring a U.S. accounting firm for tax filings and compliance management.

5. Using a registered address service through the agency to meet state requirements.

The entire process was completed within a month, allowing the company to operate smoothly in the U.S. and successfully secure angel investment.

Conclusion

While the process of establishing a company in the U.S. is well-defined, it involves multiple areas including legal, tax, and banking procedures. A small oversight can lead to serious compliance issues. Utilizing professional agency services not only improves efficiency but also ensures that the company starts on a solid compliance foundation. For businesses aiming to enter the U.S. market, careful planning, strategic selection of registration state and business structure, and expert guidance are essential first steps toward success.
