Mercury Account from Brazil for Non-US Founders in 2026

Mercury offers a modern, fee-free business checking account with FDIC insurance up to $250,000 through its partner banks. Its digital-first approach removes common barriers for non-US residents seeking US banking. Founders appreciate the integration with payment processors like Stripe and PayPal.

The platform supports international wire transfers, though fees apply for incoming and outgoing international wires. Incoming international wires typically cost $15, while outgoing can be $20 to $50, depending on the currency and destination. This makes it feasible for businesses with global revenue streams.

To open a Mercury account, a Brazilian founder must first establish a US LLC. This LLC needs a valid Employer Identification Number (EIN) from the IRS. The LLC also requires a US mailing address, which can be a registered agent's address or a virtual office address.

Mercury requires a valid passport or government-issued ID for the beneficial owner. They do not typically demand a US Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) from non-US founders. This simplifies the application process significantly for many international entrepreneurs.

Begin by visiting Mercury's website and initiating the application for a new business account. You will need to provide details about your US LLC, including its legal name, state of formation, and EIN. Accurately enter all information to avoid delays.

Next, provide personal identification documents. Upload a clear copy of your passport. Mercury will perform an identity verification check, which may involve a brief video call or additional document requests. Be ready to explain your business model and why you need a US bank account.

Mercury uses Know Your Customer (KYC) and Anti-Money Laundering (AML) procedures. This includes verifying the beneficial ownership of the LLC and the source of funds. Transparency is key during this stage.

Your business activity should align with Mercury's acceptable use policy. They generally support most e-commerce, SaaS, and consulting businesses. However, certain industries, like gambling, adult entertainment, or crypto, might face stricter scrutiny or outright rejection. Ensure your business description is clear and factual.

Once your Mercury account is approved, you can initiate your first deposit. This can be done via wire transfer from a Brazilian bank account or another international account. Be aware of any currency conversion fees from your originating bank.

Mercury provides both checking and savings accounts. You will receive a virtual debit card immediately and can request a physical card. This allows you to manage expenses, receive payments from platforms like Stripe or Shopify, and conduct daily business operations efficiently.

Regularly review your account activity to ensure all transactions are legitimate and correctly categorized. Keep your business information updated with Mercury, especially if your US mailing address or ownership changes.

As a non-US founder with a US LLC, you must comply with US tax obligations. This includes filing Form 5472 and Form 1120 with the IRS annually, even if your LLC has no US nexus and you claim zero income tax. Maintaining accurate financial records is essential for these filings.
