In Argentina, the Tax Identification Number (TIN) is a crucial element for individuals, businesses, and legal entities to comply with tax regulations. The Federal Administration of Public Revenues (Administración Federal de Ingresos Públicos, AFIP) assigns TINs to uniquely identify taxpayers for tax purposes. Ensuring the correct TIN is used is essential for accurate tax filings, legal transactions, and financial operations. All information provided in this guide is verified from official AFIP resources and trusted government publications.
Tax Identification Number Types
Argentina utilizes two primary types of TINs:
- CUIT (Clave Única de Identificación Tributaria): Assigned to businesses, legal entities, and self-employed individuals.
- CUIL (Código Único de Identificación Laboral): Assigned to employees and individuals for social security and employment purposes.
The CUIT is mandatory for tax-related activities, while the CUIL is primarily used for employment and social security identification.
