Get an ITIN as an Argentine citizen

Last updated: August 2026

Bottom line

Get an ITIN as an Argentine citizen is straightforward once the Argentina paperwork is in order. As a Hague Convention member, Argentina issues a single apostille that the US recognizes without further legalization. Treaty status (for ITIN holders): No active US treaty. Default 30% backup withholding on US-source passive income unless the ITIN holder files Form 1040-NR with effectively-connected business income.

For Argentines, a US LLC + Mercury is less about tax arbitrage and more about USD-stable banking. Pick the legal structure that survives a peso devaluation. This is the country-specific guide for Argentine 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.
