Get an ITIN as an Uruguayan citizen
Last updated: August 2026
Bottom line
Get an ITIN as an Uruguayan citizen is straightforward once the Uruguay paperwork is in order. As a Hague Convention member, Uruguay 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.
Uruguay’s territorial regime + US LLC is a clean combination for US-source online revenue. Stay tax-compliant in both jurisdictions. This is the country-specific guide for Uruguayan 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.
