Form 8938 for Americans in Mexico
Country-specific records and U.S. filing questions for Form 8938 when an American lives, works, owns assets, or has transactions connected to Mexico. Identify the records needed before agreeing on preparation scope.
Start with the facts
Country, state, residence, ownership, work location, and tax year facts come before a form conclusion.
Written scope before preparation
Describe your filing needs first. Any paid review, preparation scope, and price are agreed before work begins.
Why specified foreign financial asset reporting requires a Mexico records review
Form 8938 reports specified foreign financial assets when the applicable filing-status and residence thresholds are met, with definitions that differ from FBAR. Mexico taxes residents on worldwide income. Progressive rates from 1.92% to 35%. Preserve local registration, assessment, payment, withholding, and currency records by tax year rather than copying a local total into a U.S. form. Foreign accounts, securities, interests in entities, contracts, and other specified assets must be inventoried and tested under the tax-year thresholds and exceptions.
Residence, work, and source facts in Mexico
Obtaining a Temporary or Permanent Resident Visa strongly supports bona fide residence. Mexican tax registration (RFC number) and local employment further establish residency intent. Build the residence file from the permit, home, family, days, work, and local filing records together. For presence, residence, and work facts in Mexico: Mexico's proximity to the US makes the 330-day physical presence test manageable, but frequent border crossings must be carefully documented. Days spent in the US for business or personal trips count against your 330-day requirement. Keep payer, contract, service-location, payroll, and entity records separate. Keep the residence timeline, travel calendar, work location, and relevant local returns for the tax year being reviewed.
The Mexico accounts, products, and entities to inventory
Examples you may encounter include BBVA Mexico, Banorte, Citibanamex. Identify the legal owner, account or product type, currency, and documents available. A local product name alone does not establish its U.S. tax classification.
Documents to request before preparing Form 8938
Gather the following records, along with relevant Mexico tax returns, assessments, and payment evidence. Keep original-currency amounts and the exchange-rate method used.
- maximum and year-end account values
- custodian statements and account numbers
- ownership and beneficiary documents
- foreign entity or trust records
- FBAR comparison and exchange-rate support
Country-specific questions that can change the U.S. result
Use these questions to identify missing facts in the Mexico file:
- Is the asset held through a bank, broker, pension, trust, or entity?
- Does the country statement show the maximum value?
- Is the asset reportable on Form 8938, FBAR, both, or neither?
Common mistakes for Americans filing from Mexico
Check for these form-specific issues:
- treating Form 8938 and FBAR as interchangeable
- omitting non-bank foreign financial assets
- using the filing threshold without considering filing status and residence
Facts to review for Form 8938 in Mexico
A U.S. person in Mexico needs country-specific FATCA and FBAR account classification to test Form 8938 thresholds and exceptions.
- Mexico signed a Model 1 IGA with the US in 2012. Mexican banks actively report US account holders' information to the SAT, which shares it with the IRS. Expect to provide your SSN or ITIN when opening accounts.
- Mexican bank and financial accounts held at Mexican institutions may be reportable on FinCEN 114 when the aggregate maximum value of your reportable foreign financial accounts exceeds $10,000 at any point during the year. This includes peso and dollar-denominated accounts, as well as investment accounts at Mexican brokerages. Account type, ownership or authority, and the applicable exceptions still matter.
- Local currency: MXN.

Frequently asked questions
Does living in Mexico automatically require Form 8938?
No. The filing question depends on the form's trigger, the taxpayer's status, the legal owner, the tax year, and the records. Living in Mexico identifies the local documents to gather; it does not replace the U.S. instructions or a fact-specific review.
Which Mexico records should I gather first?
Start with residence and travel records, local tax identification and returns, bank or investment statements, income and withholding records, the legal documents for any entity or plan, and the original-currency conversion support. Then add the form-specific records listed on this page.
Can a local tax return replace the U.S. Form 8938 analysis?
No. A local return can provide evidence about income, tax paid, residence, or ownership, but U.S. forms use their own definitions and tax-year instructions. Reconcile the local return with the U.S. filing rather than copying its categories.
