Exploring U.S. Company Registration and Tax Filing Everything You Need to Know

In today’s era of global economic integration, more entrepreneurs, startups, and small business owners are setting their sights on international markets-especially the United States, known for its mature business environment and massive consumer base. Registering a company in the U.S. not only opens doors to broader market opportunities but also offers potential benefits such as tax optimization and brand enhancement. However, for first-time investors, understanding the conditions and procedures involved in U.S. company registration and tax compliance is essential.

1. Basic Types of U.S. Business Entities

When registering a company in the U.S., one of the first decisions involves choosing the legal structure. The most common types include

1. Sole Proprietorship

Ideal for small personal businesses, this structure is easy to set up, but the owner assumes unlimited liability for debts.

2. Limited Liability Company LLC

Combines the liability protection of a corporation with the tax flexibility of a partnership. It's a popular choice among startups and foreign investors.

3. Corporation C-Corp or S-Corp

Suitable for medium to large enterprises, corporations offer stronger fundraising capabilities but involve more complex tax treatment.

4. Partnership

Operated by two or more partners, profits are distributed proportionally and taxed at the individual level.

According to a recent Forbes report, over 85,000 new companies registered in Delaware in 2025, with the majority opting for LLCs. This highlights the growing preference for LLCs due to their flexibility and risk isolation advantages.

2. Key Steps to Register a U.S. Company

While the process varies slightly by state, the general steps are as follows

1. Choose the State of Incorporation

U.S. states have different corporate laws. Popular choices include Delaware, Nevada, and California. For example, Delaware is known for its robust corporate law system, specialized courts for business disputes, and favorable tax rates.

2. Select and Verify a Company Name

Ensure the chosen name isn’t already in use and complies with state regulations.

3. File Formation Documents

Submit either Articles of Incorporation for corporations or a Certificate of Formation for LLCs. These documents include details like the company name, address, shareholder information, and authorized capital. Most states allow online filing via the Secretary of State website.

4. Obtain an Employer Identification Number EIN

Similar to China’s Unified Social Credit Code, the EIN is a unique identifier issued by the IRS. Even companies without employees typically need an EIN for opening bank accounts and filing taxes.

5. Draft Bylaws or an Operating Agreement

These internal documents outline governance structures, shareholder rights, and operational procedures-especially important for corporations and LLCs.

6. Open a U.S. Bank Account

Some banks, including Citibank and Chase, allow non-U.S. residents to open accounts remotely or through third-party services.

7. Apply for Required Licenses and Permits

Depending on the industry, additional federal or state licenses may be necessary-for example, in food service or healthcare.

3. U.S. Corporate Tax Filing Requirements

The U.S. tax system is complex, involving federal, state, and local levels. Different business entities face varying tax obligations

1. Federal Tax Filings

C Corporation C-Corp Subject to corporate income tax at the federal rate of 21%. Dividends paid to shareholders are taxed again at the personal level-known as double taxation.

S Corporation S-Corp Treated as a pass-through entity; the company itself doesn’t pay federal income tax. Profits flow directly to shareholders’ personal tax returns.

LLC Default status is pass-through taxation, but LLCs can elect to be taxed as C-Corps or S-Corps. According to the 2025 NSBA Annual Report, about 65% of LLCs choose S-Corp taxation to benefit from lower overall tax rates.

2. State Tax Filings

Each state has its own tax rules

California Corporate tax rate of 8.84%, plus a minimum tax of $800 annually.

New York Rates can reach over 6.5% depending on income.

Nevada No corporate income tax, but imposes an Alternative Minimum Tax AMT.

Delaware No sales tax; corporate tax rate of 8.7%.

3. Annual Reporting and Compliance

Most states require annual reports to update information on directors, officers, and registered agents. Failure to file on time may result in penalties or suspension of the company’s active status.

Companies must also comply with anti-money laundering AML laws and the Foreign Account Tax Compliance Act FATCA, particularly when handling cross-border transactions.

4. Considerations for Foreigners Registering a U.S. Company

With the rise of remote work and digital services, more Chinese entrepreneurs are incorporating U.S. companies-especially in tech, e-commerce, and consulting. For non-residents, the following points are critical

1. Social Security Number SSN Requirement

While some states allow foreigners to register a company, applying for an EIN usually requires an SSN or Individual Taxpayer Identification Number ITIN. However, the IRS allows EIN applications via Form SS-4 without an SSN.

2. Registered Agent

Most states require a registered agent based in the state to receive legal documents and official notices.

3. Tax Planning and Compliance

Consulting with a professional accountant or attorney is highly recommended to structure your business optimally and avoid unnecessary tax liabilities.

5. Conclusion

Although the process of U.S. company registration and tax reporting may seem complex, the country’s mature business environment, transparent legal framework, and flexible tax policies continue to attract global investors. Whether you're expanding into international markets or diversifying your assets, understanding these procedures lays a solid foundation for your global strategy.
