Mexico · Banking & Funds

Mexico's banking system is regulated by the central bank (Banxico), with foreign banks (BBVA, Santander) dominating. Corporate account opening requires the legal representative in person, an RFC tax number and a genuine address; AML review is strict (registered capital over MXN 400,000 requires ultimate beneficial owner and source-of-funds information). The peso is freely convertible, but cross-border funds must be declared, and peso volatility requires hedging.

Key points

Main banks include BBVA, Santander, Banorte, etc.; strong international bank networks.
Account opening: the legal representative (Rep Legal) must apply in person, providing RFC, address proof and a business plan.
AML: registered capital over MXN 400,000 requires an ultimate beneficial owner declaration and source-of-funds proof.
FX: the peso is freely convertible; cross-border receipts/payments must be declared to SAT/Banxico.
Digital banks: some international banks offer multi-currency accounts and remote-assisted services.

Procedure

Obtain RFC tax number and registration certificate.
Prepare legal-representative documents, UBO information, address and business-substance materials.
Legal representative visits the bank in person to submit the account-opening application (some banks allow video verification).
Complete KYC and AML review.
Activate the account and inject capital to operate.

Hard requirements

RFC tax number; legal representative in person; UBO information (above MXN 400,000); genuine address.

Costs

Account-management fee by bank; minimum-deposit requirement by bank.⏱ ⏱ Timeline：Account opening about 1–2 weeks (AML review length depends on materials).

⚠ Common risks

No Rep Legal in person causes account-opening rejection.
Unclear UBO or source of funds triggers AML freeze.
Peso volatility erodes cross-border fund value.

Handbook

📘 Step-by-Step Handbook (with owner / timeline / cost / penalties)

Applies to：For companies that have completed notarial incorporation and obtained an RFC in Mexico, to open local-currency/multi-currency corporate accounts; foreign-parent background requires strong business-substance materials.

Prerequisites

Company has obtained RFC and activated e.firma (hard prerequisite for opening).
Legal representative (Rep Legal) who can attend in person or a bank supporting video verification confirmed.
Genuine office address proof (PO boxes not accepted).
Recommended: prepare UBO (natural person holding or controlling no less than 25%) and source-of-funds materials.

Step	Action	Owner	Timeline	Cost	Official form / system	Notes & penalties
1	Confirm RFC and e.firma are ready Before opening, confirm the company RFC is activated and e.firma/FIEL obtained; the bank system must read the SAT verification status, otherwise it cannot enter company information.	Finance / SAT	—	No extra fee (RFC fee already included)	RFC certificate / e.firma	Unactivated RFC is the most common cause of foreign-company account-opening failure. Penalty：Without valid RFC the bank system cannot enter information; account opening directly rejected
2	Prepare KYC / AML materials package Organise the articles of incorporation (Spanish notarised version), RPC registration certificate, legal-representative ID and address proof, UBO file (natural person holding or controlling no less than 25%), genuine business proof (e-commerce store, contracts, business plan, expected flows) and source-of-funds proof. Non-Spanish documents need certified translations.	Company / local advisor	—	Translation, notarisation and apostille fees (by number of documents)	Bank KYC package	Registered capital over MXN 400,000 requires strengthened UBO and source-of-funds declarations. Penalty：Missing or omitted materials enter manual review, delaying 2–6 weeks
3	Select bank and book appointment Evaluate BBVA, Santander, Banorte, Citibanamex, HSBC for foreign-friendliness, multi-currency support and online service; book a relationship-manager meeting. Prefer international banks supporting video KYC to reduce on-site difficulty.	Finance	—	—	Bank appointment	BBVA's branch network and digital capability are foreign-company friendly; HSBC/Citibanamex help cross-border linkage. Penalty：Wrong bank (no remote support, harsh due diligence) lengthens opening
4	Legal representative in person or video KYC opening The legal representative brings authorisation documents to the branch, or completes biometrics and signing via a bank supporting video verification; submit the account-opening form and KYC materials.	Legal representative / bank	—	—	Bank account-opening application	Most banks require the legal representative named in the articles to sign in person; fully digital opening is usually not feasible. Penalty：If the representative cannot attend and the bank lacks video support, rejection or long delay
5	Initial deposit and account activation Inject the initial deposit per bank requirement (commonly about MXN 10,000–20,000, by bank and currency, per bank publication), activating the account and debit card.	Company	—	Initial deposit (by bank)	Deposit voucher	Minimum deposit and monthly fee vary by bank; confirm in writing before opening. Penalty：Below minimum balance incurs monthly fee or even account restriction
6	Activate online banking and multi-currency At the branch set up corporate online banking, mobile banking and multi-currency (MXN/USD) functions for local receipts/payments and cross-border settlement.	Bank	—	Monthly service fee	Online banking activation	Recommend a two-layer structure of local settlement account plus international FX account. Penalty：Without activation, daily receipts/payments and payroll are affected.
7	Maintain account compliance and fund-flow consistency. Keep account fund flows consistent with CFDI invoices and bank statements; declare cross-border receipts/payments per Banxico/SAT requirements; periodically update UBO and business information.	Finance	—	Monthly/maintenance fee	Declaration / reconciliation	CFDI inconsistent with bank flows triggers SAT audit and bank risk control. Penalty：Inconsistency or unclear source of funds causes account freeze and audit.

Account fund flow inconsistent with CFDI影响：Treated by SAT as fictitious transactions, bank risk-control freeze.规避：Build invoice/bank-flow reconciliation, gap no more than 72 hours.

Below minimum balance / unpaid monthly fee影响：Fees or account restriction.规避：Confirm minimum deposit and fees in writing before opening, keep sufficient balance.
