US Expat Taxes in Mexico
Quick answer
What living in Mexico changes—and what it does not
Your country matters, but it does not answer every U.S. tax question by itself. Use this map to identify the next fact to verify before relying on a filing strategy.
| Question | What to verify | Next step |
|---|---|---|
| U.S. filing | Country of residence is not the only question. Check filing status, income type, thresholds, and the tax year. | Read the filing guide |
| Foreign earned income | FEIE analysis turns on foreign earned income, tax home, and either the Physical Presence or Bona Fide Residence test. | Check FEIE basics |
| Tax paid abroad | FEIE and the Foreign Tax Credit are different tools. Compare them before assuming one is better for your facts. | Compare FEIE and FTC |
| Foreign accounts | FBAR and FATCA are separate reporting questions. Account ownership, signature authority, and balances can matter. | Check account reporting |

FEIE Qualification in Mexico
Physical Presence Test
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.
Bona Fide Residence Test
Obtaining a Temporary or Permanent Resident Visa strongly supports bona fide residence. Mexican tax registration (RFC number) and local employment further establish residency intent.

Banking & FBAR in Mexico
Major Banks (MXN)
FBAR Reminder
All Mexican bank accounts with aggregate balances exceeding $10,000 at any point during the year must be reported on FinCEN 114. This includes peso and dollar-denominated accounts, as well as investment accounts at Mexican brokerages.
FATCA Compliance
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.
Common Pitfalls for Americans in Mexico
Failing to track border crossings accurately, which can disqualify FEIE physical presence claims
Not registering with the SAT (Mexican tax authority) when required as a tax resident, triggering penalties

Residence and the U.S. filing starting point in Mexico
A U.S. citizen or green-card holder generally continues to analyze U.S. worldwide-income filing while living in Mexico. Local residence is a separate question. Start a year-by-year timeline that identifies arrival, visa or residence status, days present, homes available, work performed, family location, local registration, and departure or renewal dates. 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. Obtaining a Temporary or Permanent Resident Visa strongly supports bona fide residence. Mexican tax registration (RFC number) and local employment further establish residency intent. Do not treat a visa label or a local tax number as a substitute for the U.S. return analysis.
FEIE and earned income for Americans in Mexico
The Foreign Earned Income Exclusion applies only to qualifying earned income and requires the relevant tax-home and presence or residence test. Salary, self-employment receipts, and services performed abroad need a work-location record. Pensions, Social Security, dividends, interest, rent, and capital gains need separate treatment. Track every trip to the United States, including partial days where the current rules count them, and preserve the residence evidence behind a bona fide claim. Compare the FEIE with the Foreign Tax Credit rather than assuming the exclusion is best.
The Mexico local tax system and the U.S. return
Mexico is described in the country record as having a worldwide tax system, with local-rate context of Progressive rates from 1.92% to 35%. The local result may depend on residence, source, remittance, employment, business activity, and the tax year. Preserve the local registration, return, assessment, payment receipt, withholding records, and any refund. A local exemption or reduced rate can change the foreign taxes available for a U.S. credit; it does not generally turn off U.S. citizenship-based reporting.
Treaty and social-security questions for Mexico
The country record currently marks the U.S.–Mexico income-tax treaty as present, signed in 1992. Its listed provisions should be checked against the current treaty text, protocol, saving clause, and residence facts. Social-security coordination is recorded as no agreement in force in this data set. Do not use a treaty headline to decide a pension, employment, self-employment, or state result without identifying the exact article and tax year.
Banks, accounts, and FATCA in Mexico
All Mexican bank accounts with aggregate balances exceeding $10,000 at any point during the year must be reported on FinCEN 114. This includes peso and dollar-denominated accounts, as well as investment accounts at Mexican brokerages. 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. Build one account inventory with the legal owner, joint owners, signature authority, institution, account type, currency (MXN), maximum value, year-end value, and closure date. Compare it with the current FBAR and Form 8938 instructions. A foreign bank’s FATCA request is a documentation issue, not automatically an IRS assessment. Keep bank correspondence and secure records separate from the U.S. income calculation.
Income source and work-location records
For an employee, contractor, or business owner in Mexico, record where services were physically performed, which entity paid, where the customer or employer is located, and where the work was managed. A Mexico payer does not automatically make every item foreign-source, and a U.S. payer does not automatically make services U.S.-source. Keep contracts, invoices, payroll, travel records, foreign withholding, local filings, and entity books. Separate personal income, business income, distributions, and investment returns before applying a credit or exclusion.
Pensions, funds, and savings products from Mexico
Ask whether a local pension, insurance policy, mutual fund, ETF, savings plan, or employer account is a pension arrangement, trust, foreign corporation, or another product for U.S. purposes. The local label may not answer the U.S. classification. Preserve plan documents, investment menus, annual statements, distributions, beneficiary records, and any annual information statement. If the product contains foreign pooled funds, screen Form 8621 and PFIC questions. If it is a pension, review treaty and Form 8938 questions separately from current income.
Residence routes and documentation in Mexico
Common residence routes in the country record include Temporary Resident Visa, Permanent Resident Visa. For each route, preserve the application, approval, renewal, local address, work permission, health coverage, and evidence of actual use. A residence permit may support a bona fide-residence analysis, but the taxpayer’s conduct and full-year facts still matter. If the taxpayer is a digital nomad, retiree, student, contractor, or family member, connect the visa record to the actual income and household timeline rather than relying on a visa marketing description.
Common Mexico pitfalls to test before filing
Failing to track border crossings accurately, which can disqualify FEIE physical presence claims Not registering with the SAT (Mexican tax authority) when required as a tax resident, triggering penalties Overlooking Mexican tax obligations on worldwide income once you become a Mexican tax resident (183+ days) These are screening prompts, not conclusions. For each one, identify the year, owner, transaction, document, and form affected. Add gifts, inheritances, foreign entities, local funds, rental property, state ties, and IRS or bank notices to the same inventory. The country-specific articles linked from this record include us-expats-mexico-tax-guide, fbar-requirements-americans-abroad, feie-vs-foreign-tax-credit; use them to frame questions, then check the current primary sources.
A records-first annual workflow for Mexico
Collect identity, residence, travel, income, account, pension, entity, local-tax, state, prior-return, and notice records. Classify each item, calculate the federal return, reconcile the foreign tax credit or FEIE, review FBAR and Form 8938 overlap, and compare the U.S. return with the local return. Save the final return, acceptance records, payment evidence, conversion rates, and unresolved issues for next year. Current official source material to check includes the current IRS, Treasury, and local authority sources. A paid consultation can turn the map into a written preparation scope before work begins.
FAQ: U.S. Taxes in Mexico
Do I have to pay taxes in both the US and Mexico?
As a US citizen or green card holder, you must file US taxes on worldwide income regardless of where you live. If you become a Mexican tax resident (183+ days), you must also file in Mexico. The US-Mexico tax treaty and Foreign Tax Credit help prevent double taxation on the same income.
Can I use the FEIE while living in Mexico?
Yes. You can qualify via the Physical Presence Test (330 days outside the US in a 12-month period) or the Bona Fide Residence Test. Given Mexico's proximity, carefully track your US visits to maintain FEIE eligibility. The 2025 exclusion amount is $130,000.
Do I need to report my Mexican bank accounts to the US?
Yes. If your aggregate foreign account balances exceed $10,000 at any point during the year, you must file an FBAR (FinCEN 114). Additionally, FATCA Form 8938 may be required if your foreign financial assets exceed $200,000 (filing from abroad). Penalties for non-compliance are severe.
Is there a U.S.-Mexico Social Security totalization agreement in force?
No. The United States and Mexico signed an agreement, but it is not listed by the Social Security Administration among agreements in force. Confirm which system covers your employment or self-employment and whether contributions may be due in both countries.
What is Mexico's RFC and do I need one?
The RFC (Registro Federal de Contribuyentes) is Mexico's taxpayer identification number. If you earn income in Mexico or become a tax resident, you need an RFC. It is required for employment, opening certain bank accounts, and filing Mexican tax returns. You can obtain one at your local SAT office.
Check the current official rules
Use the IRS for U.S. international-filing guidance, Treasury for income-tax treaty documents, and the Social Security Administration for agreements currently in force.
