What Documents Do You Need to Register a Company in the U.S.? A Complete Guide for Smooth Startup

In recent years, as globalization has accelerated, more and more entrepreneurs have turned their attention to overseas markets. As one of the most dynamic economies in the world, the United States continues to attract a large number of international investors. Even in 2025, despite ongoing global economic uncertainties, the U.S. startup environment remains open and inclusive, making it a top choice for many entrepreneurs chasing their dreams. So, what documents do you need to register a company in the U.S.? This guide will walk you through the process step by step.

1. Determine Your Business Structure - The First Step

Before registering your business in the U.S., the first thing to decide is your company structure. Common legal structures include

Sole Proprietorship

Partnership

Limited Liability Company LLC,

Corporation

Each structure comes with different implications for taxes, legal liability, and registration procedures. For example, LLCs are popular among entrepreneurs due to their flexibility and the liability protection they offer. On the other hand, C Corporations are often preferred by businesses planning to raise capital or go public.

According to the latest data from the U.S. Small Business Administration SBA, new LLC registrations increased by more than 15% in 2025, highlighting the popularity of this structure.

2. Choose the Right State for Registration

Each U.S. state has its own business registration policies and tax systems, so choosing the right state is a crucial decision.

Delaware and Nevada are among the most popular choices due to their well-developed corporate laws and favorable tax policies. For example, Delaware offers a mature legal framework for businesses and does not impose state income tax on companies that do not operate within the state-making it especially attractive for international entrepreneurs.

However, if you plan to operate your business in the U.S., it’s usually better to register in the state where you will actually conduct business to avoid additional compliance costs.

3. Prepare the Key Documents for Registration

Here are the essential documents and information you’ll need

a. Company Name

You must choose a unique and legally compliant name. Most states require the name to include a suffix such as LLC, Inc., or Corp. to indicate the legal structure. You’ll also need to check the availability of the name through your state’s business registry website.

b. Registered Address

A U.S.-based registered address is required. This can be a physical office or a virtual address provided by a registered agent. Some states, like California, require a Registered Agent located in the state to receive legal documents and official notices on behalf of the company.

c. Articles of Organization or Operating Agreement

LLCs typically need an Operating Agreement.

Corporations need Articles of Incorporation.

These documents generally include the company name, registered address, owner or shareholder details, business purpose, and management structure.

d. Employer Identification Number EIN

The EIN serves as a company’s unique identifier for tax purposes. It’s required for opening a U.S. bank account and filing taxes. Foreign individuals can apply for an EIN online through the IRS website without needing a Social Security Number SSN.

4. Obtain Licenses and Register for Taxes

After registering your company, you’ll also need to complete the following

State and Local Tax Registration - Depending on your location, you may need to register for sales tax, employer tax, etc.

Business License - Many cities or counties require a local business license before you can legally operate.

Industry-Specific Permits - Certain industries like food, healthcare, or finance may require additional permits.

U.S. Bank Account - Opening a local bank account helps manage your business finances. You’ll typically need your EIN, incorporation documents, and personal ID like a passport.

5. Special Notes for International Entrepreneurs

You don’t need to be a U.S. citizen or have a green card to register a company in the U.S., but keep the following in mind

1. The IRS has strict tax reporting requirements for foreign-owned businesses. Consider consulting a professional accountant or lawyer.

2. Opening a bank account may come with challenges, but some banks allow non-residents to open accounts remotely.

3. You can use a registered agent service to help with registration and provide a local address.

4. If you plan to live and operate in the U.S. long-term, consider applying for business-related visas like the EB-5 Investor Visa or L-1 Visa.

6. Use Professional Services to Save Time and Reduce Risk

Because U.S. state regulations can be complex, many foreign entrepreneurs turn to professional service providers to help them navigate the process. These services include

Registered agent services

Legal and accounting firms

Business registration platforms

According to a 2025 industry survey, over 60% of foreign entrepreneurs used third-party services when registering their U.S. companies. Most said it helped reduce compliance risks and save time.
