You generally cannot open a full-service bank account in Mexico from the US without traveling there, because Mexican banks require an in-person visit and, at most large institutions, proof of Mexican residency. The realistic remote options are limited: a small “level 2” digital account from a Mexican fintech, or authorizing someone in Mexico to open an account for you through a power of attorney. Whichever path you take, a Mexican account you own or control triggers US tax reporting obligations that carry heavy penalties if you ignore them.
Why Traditional Banks Require a Branch Visit
Mexican banking law requires every financial institution to verify each customer’s identity under Article 115 of the Ley de Instituciones de Crédito. The anti-money laundering rules, overseen by the Comisión Nacional Bancaria y de Valores (CNBV), require banks to collect detailed information about your identity, business activities, and the purpose of the account before approving an application.1IRS. Attachment for Mexico Financial Institutions In practice, that verification happens face-to-face, and your Mexican immigration status is the first thing a bank checks.
For a full-service account with no transaction limits, most major banks expect you to hold either a Residente Temporal (temporary resident) or Residente Permanente (permanent resident) visa. A standard tourist entry permit, the Forma Migratoria Múltiple (FMM), does not satisfy the requirements at most large institutions. Scotiabank México is an exception that specifically advertises accounts for non-resident foreigners, including visitors holding tourist permits valid for up to 180 days.2Scotiabank México. Bank Accounts for Non-Resident Foreigners Reports suggest a few other banks in expat-heavy areas occasionally open accounts for tourists, but this is the exception.
Misrepresenting your immigration status or submitting false documents can result in the bank freezing your funds and permanently closing the account under Mexico’s anti-money laundering regulations.
Digital Accounts You Can Open Remotely
If you lack Mexican residency, Mexican fintech companies offer what regulators classify as “level 2” digital accounts. These have relaxed identity requirements but come with strict caps on how much money you can move.
Banco Azteca’s Guardadito Amigo, designed for foreigners, caps monthly deposits at 3,000 UDIs, roughly 25,000 Mexican pesos, or about $1,250 to $1,500 USD depending on the exchange rate.3Banco Azteca. Guardadito Amigo Migrante Account Neobanks set their own limits: Albo allows monthly deposits up to 55,000 pesos and a total balance of 200,000 pesos. You can open an Albo account without a CURP (Mexico’s population registry code), but doing so blocks you from making interbank SPEI transfers, meaning you can spend with the debit card but cannot send money to other Mexican bank accounts.
These accounts work for day-to-day spending during trips, like groceries, restaurants, or ride-sharing. They are not designed for rent, property payments, or other large recurring expenses. For full functionality, you will need residency and a traditional account.
Opening an Account Through a Power of Attorney
If you cannot travel to Mexico but want a full account, you may be able to authorize someone already there to open one on your behalf using a power of attorney. Not every Mexican bank accepts this arrangement, and those that do may impose additional review steps, so confirm with the specific branch that they will honor the document before you spend money preparing it.
Through a Mexican Consulate
Mexican consulates in the United States are authorized to act as Mexican notaries public, and according to the consulate they are the only authorized Mexican notaries in the country.4Consulado de México. Notary Public Services A power of attorney executed at a consulate is recognized directly by Mexican institutions without a separate apostille. The fee is approximately $439, payable in cash, and you must schedule an appointment through the consulate’s booking system.5Consulado de México en Boston. Powers of Attorney If you do not speak Spanish, you must bring your own interpreter.
Through a US Notary With an Apostille
Alternatively, you can execute a power of attorney before a US notary and have it apostilled by the secretary of state in the state where the document was notarized, or by the US Department of State for documents signed by federal officials or consular officers.6U.S. Department of State. Preparing a Document for an Apostille Certificate State apostille fees are generally modest, often between $2 and $25 per document, but notarization, legal drafting, and Spanish translation add up. The total commonly runs $300 to $600.
What a Full Account Requires When You Do Travel
Once you hold temporary or permanent residency, you can gather the documents Mexican banks want. Requirements vary by institution, but the standard package includes:
- A valid US passport as your primary identification.
- Your Residente Temporal or Residente Permanente card.
- Your CURP, the 18-character Clave Única de Registro de Población assigned when you register as a resident. Some banks waive this for lower-tier accounts, but most full-service accounts require it.
- Your RFC, the Registro Federal de Contribuyentes tax identification number issued by Mexico’s tax authority (SAT), especially if you own property or conduct business in Mexico.
- Proof of a Mexican address, commonly a Comisión Federal de Electricidad (CFE) utility bill dated within the last three months and showing your name.
- A Mexican mobile number (+52) for two-factor authentication and app access. Some banks send SMS verification codes that require a reply and will not work with a US carrier. A prepaid Mexican SIM is the simplest fix.
All documents should be originals. Photocopies are commonly rejected, and some branches refuse applications with handwritten corrections or strike-throughs. BBVA México and Santander México publish downloadable application forms you can fill out in advance.
The application itself must happen at a branch. Banks verify your identity against your documents and typically collect a biometric signature, which is why digital or mailed applications are not accepted for full-tier accounts.2Scotiabank México. Bank Accounts for Non-Resident Foreigners The representative will ask about your expected account activity, sources of deposits, estimated monthly transaction amounts, and the purpose of the account. Those questions are mandatory anti-money laundering protocol, not small talk. After opening, you can manage the account through the bank’s app or web portal using the Mexican number you registered.
Cross-Border Alternatives From the US
If the residency and travel requirements feel prohibitive, multinational banks with operations in both countries offer a workaround. HSBC operates one of the largest banking networks in Mexico, with over 750 branches as of late 2025, and its global platform can simplify transfers between US and Mexican accounts. US banks such as Wells Fargo and Bank of America also let you wire money to Mexican bank accounts without holding one yourself.
Keeping your money in a US account preserves FDIC insurance and US banking protections. The trade-off is international wire fees, typically $25 to $50 per transfer, and less favorable exchange rates than a local Mexican account would give you. For occasional payments in Mexico, this simpler approach is often more practical than navigating Mexican bank requirements.

US Tax Reporting You Cannot Skip
Holding a Mexican bank account creates federal reporting obligations in the United States that account holders routinely overlook. The penalties can exceed the balance in the account.
FBAR (FinCEN Form 114)
If the combined value of all your foreign financial accounts exceeds $10,000 at any point during the calendar year, you must file a Report of Foreign Bank and Financial Accounts (FBAR) with the Financial Crimes Enforcement Network.8FinCEN. Report Foreign Bank and Financial Accounts The $10,000 threshold is aggregate across all foreign accounts you own or have signature authority over, not just one Mexican account. The FBAR is due April 15 following the calendar year being reported, with an automatic extension to October 15 that requires no separate request.9IRS. Report of Foreign Bank and Financial Accounts – FBAR
Non-willful violations can draw penalties up to $16,536 per report in 2026. Willful violations carry penalties of the greater of $165,353 or 50% of the account balance at the time of the violation. These figures adjust annually for inflation.
FATCA (Form 8938)
The Foreign Account Tax Compliance Act may separately require you to file Form 8938 with your federal tax return. For US residents filing individually, the thresholds are $50,000 in total foreign financial assets on the last day of the tax year or $75,000 at any point during the year. For married couples filing jointly, the thresholds are $100,000 and $150,000.10IRS. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets Failure to file triggers a $10,000 penalty, which can grow to $50,000 if you still do not file after IRS notification.11IRS. FATCA Information for Individuals
FBAR and Form 8938 are separate filings with different thresholds, different agencies, and different penalties. If your Mexican account crosses both thresholds, you must file both.
Deposit Insurance and Tax on Interest in Mexico
Mexico’s deposit insurance agency, the Instituto para la Protección al Ahorro Bancario (IPAB), protects bank deposits up to 400,000 UDIs per depositor per institution, roughly $135,000 USD at current exchange rates. That is comparable to the FDIC’s $250,000 in the United States, though the peso-denominated limit fluctuates with the UDI’s value and the exchange rate. Only regulated banks are covered; fintech and neobank accounts may not carry IPAB protection, so verify coverage before depositing significant amounts.
Interest earned on Mexican bank deposits is subject to ISR withholding that the bank deducts automatically. The current rate is 0.90% of the invested capital. You may be able to claim a US foreign tax credit for Mexican taxes withheld, which helps avoid being taxed twice on the same income. A tax professional familiar with both systems can help you claim the credit correctly.
