Get an ITIN as a Chilean citizen
Last updated: August 2026
Bottom line
Get an ITIN as a Chilean citizen is straightforward once the Chile paperwork is in order. As a Hague Convention member, Chile 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.
The new US-Chile treaty changes the math for many cross-border setups. If you were avoiding US-source revenue because of withholding, revisit. This is the country-specific guide for Chilean 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.
