Opening a Mexican Bank Account for a Foreign Company

Why open a Mexican account, and who sets the rules?

A company that pays suppliers, staff or taxes in Mexico usually ends up needing an account in its own name. One reason sits in the income tax law: for an expense to be deductible, a payment above 2,000 pesos must be made by electronic transfer from an account in the taxpayer's name at a financial-system institution, by nominative cheque, or by certain cards and SAT-authorised wallets, and the tax authorities may waive this in places with no financial services (LISR art. 27, III). Whether and how that applies to your company is a question for your Mexican accountant.

The rules a bank applies do not come from the bank alone. The banking law obliges credit institutions to follow general rules issued by the Finance Ministry (SHCP) after hearing the banking regulator, the CNBV. Those rules cover how well banks must know their customers, and what information and documents they collect when opening an account so that it fully proves the customer's identity (LIC art. 115). The same article requires banks to keep that identification material for at least ten years and to stop dealing with any client the SHCP puts on its confidential blocked list.

Two limits matter for planning. First, the rules set minimums: the bank must integrate a file with "at least" the listed items, so a bank can request more and can set its own commercial criteria, which these rules do not describe (rule 4). Second, a bank may not keep anonymous accounts, accounts under fictitious names, or accounts where the client or the beneficial owner cannot be identified, and it can only transact once the identification requirements are met (rule 10). An incomplete file therefore stops the process, which is why preparation matters more than speed.

A bank account is not a precondition for the tax ID itself: the SAT page for enrolling a company in the RFC does not list one among its requirements, and it even accepts an account-opening contract or a bank statement from a financial institution among the possible proofs of address (SAT). The order in practice is covered in our guide on the company registration process.

Which documents does the law say a bank collects?

The table summarizes the categories in rule 4 of the SHCP provisions, which distinguishes a Mexican legal person (fraction II) from a foreign legal person (fraction III, letter b). It lists categories, not a checklist: the bank gives you its own list, and a bank may ask for more than the minimum. The provisions say the bank collects simple copies of the documents.

Minimum identification file by type of company (rule 4; general information, not advice)
Item	Mexican company (subsidiary)	Foreign company
Identity data	Name, business purpose, nationality, RFC with homoclave, e.firma serial number, incorporation date	Name, business purpose, nationality, RFC and/or foreign tax ID with the country that issued it, e.firma serial number if any, incorporation date
Address and contact	Address, telephone, e-mail if any	Address including country, telephone, e-mail if any
Proof of legal existence	Deed or certified copy registered in the public registry, or an instrument with its registration data; if the company is new and not yet registered, a signed letter from an authorised person committing to register and report the data to the bank	A document that proves its legal existence, legalized, or apostilled if the issuing country is party to the 1961 Hague Convention; if the client does not provide it, the bank must verify authenticity itself
Tax documents	RFC cédula issued by the SAT and the e.firma certificate	The document showing the tax ID assigned by the competent authority
Proof of address	Required	Required
Representatives	Notarial instrument with the powers (if not already in the deed) and a personal ID of each representative	Notarial instrument with the powers (if not in the existence document) and a personal ID of each representative; for representatives abroad without a passport, an official original ID from the home country
Ownership and structure	Shareholding; if the client's risk grade is not low, an organization chart down to the level below the general manager and the board members	Shareholding information as for a Mexican company

The source for the table is rule 4, II and III b. For individuals the provisions list several IDs (voter card, passport, consular certificate, driver's licence, among others), and the 2024 and 2026 amendments adjusted that list, so confirm the current one with the bank. They also treat a driver's licence or federal-type credential from the home country as valid for representatives abroad without a passport; the bank is responsible for verifying those documents.

A caution on versions. The full text of these provisions we found on an official site is a compiled version that the CNBV's publication itself marks as unofficial, covering amendments up to 3 March 2022 (compiled provisions). The Diario Oficial published a further amending resolution on 28 August 2024 (DOF), and a resolution signed on 9 July 2026 is posted on the Segob portal (SIDOF); we did not verify its DOF publication date, and it gives banks 18 months to adapt. The 2024 resolution amended rule 4 (among other things the item on the representatives who can bind a Mexican company). The 2026 resolution amends rule 4, fraction I, letter b, numerals i and iii (individuals' ID and proof of address) and rule 4 Bis (trusts); the company file cross-refers to those numerals for proof of address and representatives' ID. Treat the table as a map of categories and ask the bank or your lawyer for the current list.

Who is a beneficial owner, and why ask?

A beneficial owner is the individual who, directly or through other persons or mechanisms, obtains the benefits of an account and is ultimately the true owner of the funds. The term also covers the individual or group of individuals who exercise control over a company (rule 2, XXXII). For a Mexican or a foreign company client, the bank must identify the owners who control it and gather their data and documents.

The rule has a numeric test: where no individual holds or controls, directly or indirectly, 25% or more of the capital or voting rights, or otherwise controls the company, the administrators are deemed to exercise control. If the administrator is itself a company or a trust, control is attributed to the individual that company or trust appointed. The bank collects a written declaration from the client's legal representative stating who the beneficial owners are, and if it has reason to doubt the declaration it must take reasonable measures to determine them (rule 4, II c).

For each beneficial owner the bank collects the same data and documents it would collect from an individual client; for the address, the place where the person can be located is enough. It also checks whether the beneficial owner is a politically exposed person, and if so it applies additional rules (rule 4, VI). In practical terms, a foreign group should be able to draw its ownership chain down to named individuals, with identity documents, before the first appointment. Listed companies and their majority-owned subsidiaries are treated differently under rule 4, VI; ask the bank how that exception works for your group.

What should you prepare before the first bank appointment?

The sequence below is our reading of the provisions above, not a bank's procedure. Your lawyer or the bank may reorder it.

Decide which entity holds the account
The rules contemplate both a Mexican legal person (rule 4, II) and a foreign legal person (rule 4, III b). Which of the two a particular bank is willing to onboard is the bank's decision, and we found no official source on it. If you are forming a Mexican company, see the registration process first (rule 4).
Get the RFC and the e.firma first, for a Mexican company
The Mexican-company file lists the RFC, the e.firma serial number, the RFC cédula and the e.firma certificate, so those documents normally come before the bank (rule 4, II). The path is explained in our guide on the RFC and e.firma.
Prepare the foreign documents
For a foreign company, the document proving legal existence and the tax-ID document need legalization or, where the Hague Convention applies, an apostille. Ask the bank and your notary whether a translation is also wanted, because the provisions we read do not say (rule 4, III b).
Name the representatives and check their powers
Each representative needs a personal ID, and the powers must be in a notarial instrument unless they are already in the deed or existence document. Check with a Mexican notary that the powers of attorney you sign abroad will be accepted in Mexico (rule 4, II b iv and III b ii.3).
Map the ownership down to individuals
Prepare the shareholding, the people who hold or control 25% or more, the administrators, and a written declaration (which may be electronic) from the legal representative. Be ready to answer whether any of them is a politically exposed person (rule 4, II c and VI).
Ask how the bank wants to open the account
Ask in writing whether the bank opens company accounts in person only or also remotely. Since the 28 August 2024 amendment, rule 4 Ter on non-face-to-face opening refers to clients of Mexican nationality; we found no rule extending it to foreign companies, so ask the bank in writing (rule 4 Ter). We found no official list of which banks offer remote company accounts.

How do you compare banks and check they are authorized?

The CNBV states that 50 authorized banks operate in Mexico under its supervision, and that it publishes the Padrón de Entidades Supervisadas, which lists the authorized entities in the sector that carry deposit insurance. The same page mentions that insurance protects savings up to 400,000 UDIs (CNBV); whether and how that figure applies to a company account is a question for the bank. We do not recommend any bank and we found no official ranking.

For comparing institutions, CONDUSEF runs the Buró de Entidades Financieras, a tool that shows the complaints institutions receive, the abusive contract clauses in force, whether they offer financial-education programs, and general information about their products (CONDUSEF). Its dedicated site did not open from our tools because of a certificate error, so we only read CONDUSEF's description of it on gob.mx; check the tool itself, and whether it covers company accounts.

We found no official figure for opening time or account fees. Ask each bank the same questions and keep the answers in writing: the current document list for your type of company, whether foreign shareholders or representatives must attend, whether documents in Chinese or English are accepted, what happens if a document is missing, and the full schedule of commissions for the account and for international transfers. Then have your lawyer or accountant compare the answers.

What should you do next, and who should you ask?

This guide explains the minimum rules; it does not tell you which bank will accept your structure or how long it will take. The questions that decide your case are legal and tax questions, so a licensed Mexican lawyer or notary should confirm the entity, the powers and the foreign documents, and an accountant should confirm the tax side. If you want to check where your plan stands, you can take the free assessment: it takes a few minutes, carries no obligation and has no price attached. Xin Puente introduces independent Mexican professionals and coordinates in Chinese; it is not a bank, a law firm or an accounting firm, and you contract and pay the professionals directly.

Frequently asked questions

Can a foreign company open a Mexican account without a Mexican subsidiary?

The identification rules include a category for foreign legal persons, with their own document list, so they are not excluded by the rules we read (rule 4, III b). Whether a given bank accepts such a client is the bank's decision, and we found no official source on it. Ask each bank, and ask a Mexican lawyer whether a subsidiary suits your plan better.

Can the account be opened from China?

Rule 4 Ter (as amended in 2024) covers non-face-to-face opening for clients of Mexican nationality; we found no rule for foreign companies (rule 4 Ter). Whether a bank allows it from China is the bank's call, so ask each bank in writing what it offers and what it requires of foreign representatives.

How long does opening an account take?

We found no official figure. The time depends on the bank, on how complete the file is, and on legalization of foreign documents, which this guide cannot predict. Ask the bank for an estimate in writing and have your lawyer confirm.

How much does a company account cost?

We found no official figure. Each bank sets its commissions. CONDUSEF's Buró de Entidades Financieras is the official comparison tool for institutions (CONDUSEF); ask each bank for its full fee schedule in writing, including international transfers.

Why might a bank not complete the opening?

The provisions forbid a bank to keep accounts where the client or the beneficial owner cannot be identified, and it can only operate once the identification requirements are met (rule 10). A bank must also stop dealing with any client on the SHCP's confidential blocked list (LIC art. 115). Beyond that, the bank's commercial criteria are not described in the rules we read, so ask the bank directly.

What does Xin Puente do in this process?

We introduce independent, licensed Mexican professionals to Chinese companies and coordinate in Chinese. We are not a bank, a law firm, a notary or an accounting firm, and we give no legal, tax or banking advice. You contract and pay the professionals directly.
