Business bank account in Mexico: how to open one as a foreigner in 2026

Why opening a business bank account in Mexico is harder than it looks

Mexico has strict anti-money laundering obligations under the Federal Law for the Prevention and Identification of Transactions with Illegally Sourced Funds (LFPIORPI) and Banco de México regulations. Banks must know their business clients at a level of detail that includes not only the company but who ultimately controls it — the so-called beneficial owners.

For a company with foreign shareholders, this means the bank needs to understand and verify the ownership structure down to real individual persons with verifiable identification. If those individuals are in Russia, Ukraine, a FATF high-risk country or simply in a country where the bank has no correspondent banking relationship, opening an account can become very complicated — even if the company is perfectly incorporated and the RFC is current.

Before going to any bank, three things must be in place: the legal entity's RFC active with a verifiable fiscal domicile, the corporate e.firma obtained, and the beneficial owner declaration ready. Without those three pieces, the conversation with the business banking executive will not move forward.

The beneficial owner obligation: what changed in 2022

Since January 2022, article 32-B Ter of the Federal Tax Code (CFF) requires all legal entities to identify, collect information from and retain documentation of their beneficial owners. A beneficial owner is the individual who directly or indirectly:

• Holds more than 25% of the share capital, or
• Exercises control over the entity by any other means (management, voting rights, agreements)

Banks are required by their own AML rules to request this information before opening any business account. For an SA de CV with two shareholders at 50% each — one Mexican and one foreign — both are beneficial owners and both must be documented: full name, date of birth, RFC or equivalent foreign tax ID, address, nationality and ownership percentage.

If the foreign shareholder does not have a Mexican RFC (common when the company was just incorporated), banks accept the tax identification number from the country of origin, but they need additional documentation to support it. A passport alone is no longer sufficient.

Documents banks actually request: the real list, not the brochure version

The official list each bank publishes on its website is usually incomplete. What is actually requested when opening a business account for an SA de CV with foreign shareholders:

The "description of economic activity and source of funds" seems like a formality but is in practice the document that generates the most rejections. Banks want specifics: not "consulting services" but "tax and accounting advisory to technology companies in the United States and Canada, whose payments are received via SWIFT wire transfer from foreign accounts in US dollars." The more concrete, the lower the probability that the compliance officer escalates the file for additional review.

Which banks are most accessible for companies with foreign shareholders

Fintechs as a solution for the first year

While the traditional bank processes the file — or if the company does not yet have the tax history they require — there are fintech options that allow operating from the first month:

Fintechs do not replace a traditional bank account for everything: not all issue statements in the format required by notaries, large suppliers or SAT for certain transactions. But they do provide a CLABE, allow receiving domestic and international payments, and enable CFDI issuance from the first month of operation. For service companies billing abroad, Oyster in particular has worked as a bridge solution during the first six months.

Personal vs. business account: why SAT distinguishes them

One of the most common mistakes in new companies with foreign shareholders is using the personal account of the legal representative or one of the shareholders to receive the first client payments. It seems like a practical solution while the business account is being opened. The problem is that those deposits are recorded as personal income — not the company's — and SAT cross-checks the data.

If the SA de CV issues invoices to its clients but the payments arrive in a personal account, there is an inconsistency that can generate a SAT requirement: the company has billed income with no bank deposits to back it up, and the individual has deposits that do not match their own declared income. Neither situation holds up well in a review.

The cleanest option to receive client payments before having the business account is through a fintech registered as a financial intermediary, which generates a payment receipt in the company's name (not the individual's). Several platforms in the table above allow this from day one with just the company's RFC.

Real case: the company that took longer to open a bank account than to incorporate

An SA de CV providing digital marketing services to clients in Spain and Argentina, with two shareholders — one Ukrainian resident in Mexico with permanent residency and one Mexican — was incorporated at a notary in four business days. What followed was different.

The first bank rejected the account opening because the Ukrainian shareholder had no Mexican RFC and the bank classified the transaction as high-risk based on geographic origin. The second bank asked for two years of tax returns that the company obviously could not have. The third bank accepted the file but kept it in compliance review for 47 days, requesting additional documentation three times: first the foreign shareholder's proof of address with apostille, then a signed contract with a Spanish client as evidence of activity, and finally a banking reference letter from the shareholder's country of origin.

The company operated its first two months with an Oyster account, opened in 48 hours with the company's RFC, the legal representative's ID and basic company data. They received their first payments from Spain, issued CFDIs correctly and filed their first monthly returns with verifiable bank movements. When they finally opened the account at Santander, the file was simpler because they already had two months of Oyster statements as activity history.

The sequence we derived from that experience: fintech from day one to operate, traditional bank in parallel from the first month as a medium-term process. Do not wait for the bank to start billing — that delays the entire tax cycle of the first year.

Checklist before presenting your file at the bank

• Company RFC active, with correct economic activity and verifiable fiscal domicile (not the accountant's address).
• Corporate e.firma obtained — many banks require it for signing the account contract.
• Incorporation deed registered in the RPPC if the bank requires it — verify before the appointment.
• Beneficial owner form complete with data for all shareholders above 25%, including foreign tax ID where applicable.
• Company fiscal domicile proof no older than 3 months.
• Description of economic activity, typical clients and expected source of funds — on company letterhead, signed by the legal representative.
• For new companies: first-year financial projection and, if available, signed client contracts as evidence of activity.
• For foreign shareholders: current passport, current immigration document (residency card), RFC if already obtained, and Mexican address proof.

If you are planning to open a company in Mexico and are still in the incorporation phase, the ideal time to prepare banking documentation is during the notarial process — not after. The notary can indicate whether the deed needs any additional element for the banks they work with regularly.
