FBAR and Mexico Bank Accounts: What US Citizens Must Report

US citizens, green-card holders, and US tax residents with Mexican bank accounts have the same FBAR obligation as anyone with foreign financial accounts. The five banks below are among the largest in the country by assets. This post is education-only -- it explains the filing rule and names the banks; it does not estimate any penalty or guarantee any outcome. An Enrolled Agent can review your specific facts.

The Mexican banks US filers report most often

These five institutions are among the largest banks in the country by assets:

  • BBVA Mexico -- the largest bank in Mexico by assets.

  • Banorte -- a major Mexican bank, domestically owned.

  • Santander Mexico -- the Mexican subsidiary of the Spanish Santander group.

  • Citibanamex -- the Mexican arm of Citi, formed from the former Banamex.

  • HSBC Mexico -- the Mexican subsidiary of the global HSBC group.

Use these exact names when you enter account information on FinCEN Form 114. Do not translate them, shorten them, or substitute an English version -- the form wants the bank's name as it appears on your statements.

The FBAR rule, plainly

FBAR is FinCEN Form 114, and the trigger is aggregate. The rule is not per-account and not per-bank. You must file when the combined maximum value of ALL your foreign financial accounts exceeds USD 10,000 at any point during the calendar year. "All" means every account in every country -- your BBVA Mexico checking, a Santander Mexico savings, a Banorte investment account, and any account anywhere else, all summed together.

Two details catch people off guard every year:

  • Maximum value, not year-end balance. FBAR asks for the highest balance each account reached at any moment during the year. A year-end statement is not enough. You may need monthly statements or the bank's own max-balance figure.

  • Filed separately from your tax return. The FBAR is filed through FinCEN's BSA E-Filing system, not with your Form 1040. The deadline is April 15, with an automatic extension to October 15 -- no extension request is needed, the extension is built in.

How Mexico shares account information with the IRS

Mexico participates in the automatic exchange of financial account information with the United States. This means Mexican financial institutions report account information to Mexican tax authorities, which transmit that data to the IRS. The practical effect is that the IRS can receive account-balance and payment information from Mexican banks, which makes non-filing visible to both governments.

FBAR and FATCA are separate regimes with separate purposes, but they overlap on the same accounts. Filing the FBAR does not satisfy FATCA reporting, and FATCA reporting does not replace the FBAR.
