How to Register a US Business from Brazil

With Firstbase since:

Welcome to our guide on registering your business in the United States from Brazil! We understand that starting a business can be overwhelming, especially when it involves navigating through different countries' regulations. But don't worry, we're here to help make the process as smooth as possible.

In this step-by-step guide, we'll walk you through the essential requirements and procedures you need to follow to register your business in the US. From researching the registration requirements to fulfilling tax obligations, we've got you covered.

So, let's dive in and get your business up and running in the land of opportunity!

Step 1: Research US Business Requirements and Benefits

First things first, as a business owner from Brazil, you need to familiarize yourself with the specific registration requirements for foreign businesses in the US. Each state has its own rules and regulations, so it's crucial to know what applies to you.

You should also have a clear understanding of the advantages of US incorporation for international business owners. While incorporation can be a big step forward, it isn't necessarily the right choice for every situation.

To make things easier, we've developed some resources covering the key elements that founders should be aware of before incorporating a US business. Check these out if you need more info:

Step 2: Choose a State and Business Structure

Now that you've done your research on US business registration requirements, it's time to move on to the exciting part - choosing a business structure! This is an important decision that will shape the way your business operates and how it is taxed. You'll also need to decide which state to incorporate your new business in.

There are several business structures to choose from, each with its own advantages and disadvantages. The most common options are LLCs and C-Corps — let's take a closer look at how each of these entity types work.

Limited Liability Company (LLC)

An LLC combines the limited liability protection of a corporation with the flexibility and simplicity of a partnership. This business structure is a popular choice for many small businesses because it offers personal asset protection and pass-through taxation.

The main limitation of LLCs is that they can't issue stock. If you're planning to offer equity to investors, employees, advisors, or other stakeholders, you'll need to go with a C-Corp.


If you're planning to grow your business and attract investors, forming a c-corporation might be the way to go. A corporation is a separate legal entity from its owners, which means it can enter into contracts, sue or be sued, and issue stock to raise capital.

Remember, choosing the right business structure is crucial to the success of your venture. It's a good idea to consult with a legal or tax professional to understand the implications of each option and determine which one aligns best with your goals and needs.

Step 3: Register Your Business with the State

So, you've done your research, chosen a business structure, and obtained an Employer Identification Number (EIN). Now it's time to take the next important step – registering your business with the state. This step is crucial for establishing your business's legal presence in the United States and ensuring compliance with state regulations.

If you're registering your business from Brazil, it's essential to understand the specific requirements and processes involved. Each state in the US has its own set of rules and procedures for business registration, so it's important to consult the official website of the state where you plan to operate.

Of course, we recommend incorporating through Firstbase since we'll handle the legwork for you. Here are the main steps you'll need to complete if you decide to go it alone:

  1. Choose a business name: Select a memorable name for your business that complies with the state's naming regulations. Note that you won't be able to use a name that's too similar to an existing business in your target state. Use our business name search tool to quickly check name availability.
  3. File the registration forms: Complete the registration forms provided by the state's official website. These forms typically require information about your business, its owners, and its intended activities. Pay attention to accuracy and completeness while filling out the forms.
  5. Pay the required fees: Most states charge a registration fee, which can vary depending on your business type and the state's regulations. Make sure to check the fee schedule and submit the payment along with your registration forms.
  7. Wait for approval: Now, all that's left is to wait for your application to be processed by the state government! You may be asked to revise and resubmit if there are any issues with your filing, so be careful to get it right the first time around.

Remember, registering your business with the state is a critical step in establishing your presence and complying with legal obligations. Working with Firstbase will ensure a smooth process and remove the headache of US business incorporation.

Step 4: Obtain an Employer Identification Number (EIN)

Before you can register your business with the state, you'll need to obtain an Employer Identification Number (EIN) from the Internal Revenue Service (IRS). This number will be used to identify your business for tax purposes. We'll apply for an EIN on your behalf if you choose to incorporate with Firstbase.

As a business owner in Brazil, it's important to note that you'll need to have a valid Individual Taxpayer Identification Number (ITIN) in order to apply for an EIN. You can apply for an ITIN by filling out Form W-7 with the IRS.

Once you have your ITIN, you can apply for an EIN online through the IRS website. The application process is free and typically takes less than an hour to complete.

It's important to keep in mind that your EIN is not only necessary for tax purposes, but also for opening a business bank account and hiring employees. Without an EIN, you won't be able to legally hire employees or pay taxes.

  • Make sure to have your ITIN before applying for an EIN
  • Apply for an EIN online through the IRS website
  • Your EIN is necessary for tax purposes, opening a business bank account, and hiring employees

Step 5: Fulfill Additional State Requirements

Now that you have registered your business with the state, it's time to dive into fulfilling additional state requirements. These requirements may vary depending on the state where you are registering your business from, so it's important to do your research and understand what needs to be done. Again, we recommend reading our ongoing compliance requirements guide to get an idea of your obligations as a US business owner.

1. Obtain Necessary Permits and Licenses

Depending on the nature of your business, you may need to obtain specific permits and licenses from your state government. These permits and licenses ensure that you are operating legally and in compliance with local regulations. Make sure to check with your state's licensing board or department to determine which permits and licenses are required for your particular industry.

2. Register for State Taxes

Just like with federal taxes, you will also need to register for state taxes. This includes sales tax, income tax, and any other applicable taxes based on your business activities. Each state has its own tax requirements, so it's crucial to familiarize yourself with your state's tax laws and regulations. Registering for state taxes will ensure that you remain in compliance and avoid any penalties or fines.

3. Comply with Employment Laws

If you plan on hiring employees for your business, you will need to comply with state employment laws. This includes obtaining workers' compensation insurance, paying unemployment insurance taxes, and adhering to minimum wage and overtime laws. It's important to familiarize yourself with your state's employment laws to ensure that you are treating your employees fairly and legally.

Remember, fulfilling additional state requirements is an essential part of running a successful business in the United States. By doing your due diligence and staying compliant with state regulations, you are setting yourself up for long-term success and growth. Good luck with your business venture in the United States!
