While the exact registration process may vary slightly from state to state, the following materials are generally required

1. Company Name and Name Availability Check

Before registering, ensure the chosen company name is not already taken in the target state. Most states offer online name search tools via the Secretary of State’s website.

2. Registered Address and Registered Agent

U.S. law requires all companies to have a physical address in the state of registration and to appoint a Registered Agent. This individual or service is responsible for receiving legal documents and official notices. The agent must be at least 18 years old and have a fixed office in the state.

3. Articles of Incorporation or Articles of Organization

This is the core document for company registration, typically including the company name, registered address, shareholder information, business purpose, and share structure if applicable. It must be filed with the state along with the required registration fee.

4. Shareholder and Director Information for Corporations

For C Corporations and S Corporations, details of shareholders and directors-including names, addresses, and share percentages-are required. LLCs typically only need member information.

5. Social Security Number SSN or Individual Taxpayer Identification Number ITIN

U.S. citizens must provide an SSN, while non-citizens must obtain an ITIN before applying for an Employer Identification Number EIN.

6. Employer Identification Number EIN

An EIN serves as the company’s tax ID, necessary for filing taxes, opening a bank account, and other business activities. It can be applied for online via the IRS website.

Although not required in all states, an Operating Agreement is a crucial internal document outlining the rights and responsibilities of LLC members. It is highly recommended to draft one at the outset.

8. State Tax Registration and Business License

After registration, you must apply for a state tax ID and obtain a Business License from the local government. Certain industries, such as food services, healthcare, and finance, may also require additional professional licenses.

3. Recent Trends and News

The registration process has become increasingly streamlined.

In 2025, U.S. Citizenship and Immigration Services USCIS updated its guidelines for entrepreneurial visas, encouraging international entrepreneurs to apply for EB-2 or EB-5 visas through U.S. company registration. This means that registering a U.S. company is not only a business move but potentially a path to immigration.
