FATCA compliance makes Mexican banks nervous about American clients. Some refuse. Some accept but limit services. Here's the current state — which banks work, what documents you need, and which US accounts to keep.
FATCA (Foreign Account Tax Compliance Act) requires foreign banks to report American account holders to the IRS. The compliance burden is expensive, so many Mexican banks would rather decline American clients than deal with the reporting. This isn't personal — it's a cost calculation. But it means you need to know which doors to knock on.
Based on current verified reports, these banks are accepting American clients: BBVA Mexico (the most American-friendly, largest branch network), Citibanamex (good if you have an existing Citi relationship in the US), Intercam (smaller but experienced with foreign clients), and Actinver (wealth management focus, higher minimums). Banorte, Santander, and HSBC accept Americans in some branches but not consistently.
The guide includes specific branch locations in CDMX, Guadalajara, and Mérida that are known to handle American clients smoothly, plus the name-level contacts where available.
You'll typically need: valid passport, Mexican residency card (temporary or permanent) OR proof of address in Mexico, RFC number (tax ID — obtainable even on a tourist visa in some cases), CURP (if you have residency), proof of income or employment, and a completed W-9 form (US tax form the bank files under FATCA).
Some banks will open an account with just a passport and proof of Mexican address (utility bill, rental contract). The guide covers the minimum requirements per bank and which documents to bring to avoid multiple trips.
Absolutely. Keep at least one US checking account and one US credit card. You'll need them for: US tax payments, receiving US-source income, maintaining US credit history, Venmo/Zelle/PayPal access, and emergency funds accessible without Mexican banking delays. Schwab's checking account is popular with expats for its unlimited ATM fee reimbursement worldwide.
Wise (formerly TransferWise) is the most cost-effective option for most transfers, with mid-market exchange rates and fees of 0.5-1%. Bank wire transfers cost $25-50 per transfer plus unfavorable exchange rates. The guide covers the cheapest transfer methods by amount size and frequency, plus how to handle large transfers (property purchases) without getting flagged.
Yes. If your Mexican accounts (checking, savings, investment, retirement — all combined) exceed $10,000 in aggregate value at any point during the year, you must file an FBAR. This includes accounts where you have signature authority, even if they're not in your name. The penalty for non-filing starts at $10,000 per account per year. Read the full FBAR guide →
Yes, but watch for foreign transaction fees (typically 3% per transaction). Cards with no foreign transaction fees include Chase Sapphire, Capital One Venture, and Schwab Investor Card. The guide lists the best US credit cards for Americans in Mexico, including which ones work best for peso transactions and online Mexican payments.
Mexico's Fintech Law regulates crypto exchanges. Bitso is the largest Mexican exchange and accepts Americans with proper KYC. Digital banks like Hey Banco and Klar may accept Americans for basic accounts. However, all crypto holdings are reportable to the IRS, and Mexican exchanges may report to SAT. The guide covers the tax implications of holding and trading crypto while living in Mexico.
