US LLCs from Argentina: Banking for Non-Resident Founders in 2026

Opening a traditional US bank account from Argentina for your LLC can be difficult in 2026. Most large US banks still prefer in-person visits from at least one company principal. This is due to enhanced Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations.

While some major banks might offer remote options for established businesses with existing US ties, it is rare for a newly formed LLC with Argentine founders. Founders should prepare for a potentially frustrating process if targeting traditional institutions without a US presence.

Fintech companies have significantly streamlined the remote banking process for non-US residents. Platforms like Wise (formerly TransferWise) and Mercury offer digital accounts that cater specifically to US LLCs with international owners. They provide US bank account details (routing and account numbers), virtual debit cards, and international transfers.

The primary advantage of these fintech providers is their fully remote onboarding process. They utilize advanced online identity verification methods, making it possible for Argentine founders to set up a US business account without traveling. This saves time and significant travel costs.

Wise offers a multi-currency account that includes US dollar banking details. For an Argentine founder, this means you can receive USD payments, hold funds, and make payments just like a local account. The setup process is entirely online, requiring your LLC formation documents and personal identification.

Wise is known for its transparent, low fees for international currency conversions. While not a full-service bank, it serves as an excellent operational account for receiving payments from platforms like Stripe or PayPal and managing routine expenses. Fees for international transfers are typically a percentage of the amount, often below 1% for major currency routes.

Mercury is a US-based fintech company offering FDIC-insured banking specifically for startups and e-commerce businesses. Their onboarding for US LLCs owned by non-residents is one of the smoothest in the industry, even for Argentine founders. You will need your EIN confirmation letter and LLC formation documents.

Mercury provides checking and savings accounts, physical and virtual debit cards, and integrations with payment processors like Stripe. It is often preferred by founders seeking investor funding due to its more traditional bank-like features and focus on business growth. There are no monthly fees for their basic accounts.

Regardless of the banking option, your US LLC will need an Employer Identification Number (EIN) from the IRS. This is a crucial step for any US business. Non-US residents can obtain an EIN without an SSN or ITIN by filing Form SS-4.

Other key documents include your LLC's Articles of Organization (or Certificate of Formation), Operating Agreement, and a valid passport. All applicants for the bank account will need to provide their personal identification for KYC purposes.

All US LLCs, including those owned by Argentine non-residents, must comply with US tax and regulatory obligations. This includes filing Form 5472 and Form 1120 (informational returns) if the LLC is a single-member disregarded entity. These forms report transactions between the LLC and its owner.

A critical new requirement in 2026 is the Corporate Transparency Act (CTA), enforced by FINCEN. Most US LLCs must report their beneficial ownership information (BOIR) to FINCEN. This includes details of individuals who directly or indirectly own or control 25% or more of the company, or who exercise substantial control. Failing to comply can result in significant penalties, up to $500 per day. Bastion Formations assists with this filing.

Once your US LLC has a bank account, integrating with payment processors like Stripe or PayPal becomes straightforward. Both platforms require a US bank account, a US street address, and an EIN. For Argentine founders, having a US LLC with a legitimate US bank account simplifies these integrations, opening up access to the US market.

Ensure your US LLC's registered agent provides a physical street address that can receive mail. This is essential for compliance with payment processor requirements and for overall business correspondence.
