Get an ITIN as a Mexican citizen

Last updated: August 2026

Bottom line

Get an ITIN as a Mexican citizen is straightforward once the Mexico paperwork is in order. As a Hague Convention member, Mexico issues a single apostille that the US recognizes without further legalization. Treaty status (for ITIN holders): Active US treaty available, use Form W-8BEN to claim reduced withholding once the ITIN is assigned.

RFC + US LLC is a clean stack for US-customer revenue. SAT treats the LLC as a foreign entity; declare correctly and you avoid double taxation. This is the country-specific guide for Mexican citizens to get an itin, apostille, banking, and treaty notes that change by jurisdiction. For the canonical procedural sequence (the steps everyone follows regardless of citizenship), see the main ITIN application page.

An ITIN (Individual Taxpayer Identification Number) is the IRS-issued tax ID for non-US residents without an SSN. It unlocks US tax filings, US bank accounts at issuers that require a TIN, and, most importantly for digital nomads, a US credit file. The application is Form W-7 + a valid reason code + original ID documents. Wrong reason code is the #1 cause of rejection.
