Argentina TIN number guide
Clave Única de Identificación Tributaria (CUIT)
"Clave Única de Identificación Tributaria" (CUIT) is a unique identification number for tax purposes in Argentina. It is often referred to as the Tax Identification Number (TIN) or Tax ID. The CUIT is used to identify individuals, businesses, and entities for tax-related matters.
Individuals and businesses obtain their CUIT through the Administración Federal de Ingresos Públicos (AFIP), which is the tax authority in Argentina. Upon registration, a CUIT is granted by AFIP; thus, he/she acquires a tax identity vis a vis third parties, and is therefore entitled to develop its activities on a legal basis.
CUIT Format
11-digit number formatted as NN-NNNNNNNN-N (the first 2 digits indicate the type of person: 20 for men; 27 for women; 23, 24, 25 or 26 for both (in case there is an identical CUIT), and 30 or 33 for legal persons, the next 8 digits are: in the case of individuals, the ID (DNI) number; and in case of legal persons, it is assigned by the AFIP, the last digit is randomly assigned)
Where to find CUIT?
Once the CUIT has been assigned, persons become part of the taxpayers’ register of the Federal Administration.Any person may enter the AFIP’s website and see the Proofs of Registration (General Regime) or Registration of Monotributo (Simplified Tax Regime for Small Taxpayers) of any of the registered taxpayers, thus having access to the information regarding their tax status.
Clave Única de Identificación Laboral (CUIL)
"Clave Única de Identificación Laboral" (CUIL) is an identification number used in Argentina for labor and social security purposes. It is assigned to individuals for the purpose of tracking their employment and social security contributions.
Identification Code (CDI)
The Identification Code - CDI - represents a numeric code that the AFIP issues to individuals who are not required to have a CUIT or CUIL (see below) due to the fact that there is no tax or social security reason to have one but otherwise is required to be identified for certain procedures.
