Requirements for filing taxes in the US if you are not a resident company

If your company is not domiciled in the United States and you wish to expand or register in an American state, there is a series of mandatory preparatory steps that you must complete first.

The main objective of these steps is to establish a basic fiscal and operational presence in the country.

Key Required Documents and Assets

Before starting the formal state registration, your company must obtain the following essential elements:

• Legal Entity in the U.S.:  This is the first step and the legal basis for your operation in the country. We recommend setting up the company in Delaware or Wyoming.
• Mailing Address in the U.S.:  A physical or virtual address to receive official correspondence.
• Federal Employer Identification Number (EIN): The equivalent of the tax ID for tax purposes.
• Commercial Bank Account:  Necessary to manage transactions and comply with tax obligations.

🛠️ Step 1: Entity Creation, Address, and EIN Acquisition

The most efficient and fastest way for non-U.S. companies to meet the first three requirements is by using specialized services, such as the following:

| Platform | Primary Benefit |
| Stripe Atlas | Ideal for tech companies and startups. Simplifies the formation of a C-Corp in Delaware. |
| Firstbase | Offers LLC formation options in various states (such as Wyoming), which may be more suitable for certain business models. |

🏦 Step 2: Opening a Commercial Bank Account

For international clients, the simplest way to open an American commercial bank account remotely is through Wise.

Wise offers business accounts with U.S. banking details (including routing and account numbers), facilitating international transfers and dollar management.

Once you have your  U.S. entity ,  EIN ,  U.S. address , and  bank account , you will be ready to move to the next level and formally register your company in the state of your choice.
