2. Step-by-Step Registration Process

1. Choose a State

Each U.S. state has different requirements for company registration. Delaware, Nevada, and Wyoming are popular choices due to their business-friendly laws, low taxes, and strong privacy protections.

2. Search and Register the Company Name

Check the availability of your desired business name on the state’s official website. Once confirmed, submit the registration application and pay the required fee.

3. Appoint a Registered Agent

Every company must designate a registered agent who will receive legal documents and official notices. The agent must have a physical address in the state of registration.

4. File Formation Documents

Typically, you’ll need to file either Articles of Incorporation for corporations or Articles of Organization for LLCs. These documents outline the company structure, shareholder details, and business scope.

5. Obtain an Employer Identification Number EIN

An EIN serves as the company’s tax ID. It is required for tax filings, opening a bank account, and hiring employees. You can apply for one for free via the IRS website.

6. Open a Bank Account

After registration, open a business bank account. Most banks will require your EIN, formation documents, and a certificate of good standing. In recent years, online banks such as Chase, Wells Fargo, and Revolut have made the process easier for startups.

3. Setting Up Startup Accounts and Financial Management

Beyond registration, entrepreneurs should also focus on financial management and account setup. U.S. banks and fintech companies offer a variety of options

1. Traditional Business Bank Accounts

This is the most basic and essential account for managing daily business transactions. Banks like Bank of America and Citibank offer strong support for business clients.

Additionally, the rise of remote work has enabled entrepreneurs to register a U.S. company without physically being present in the country. Some states allow the use of registered agent services to complete the process, requiring only online submission of documents.
