Introduction
In Italy, the Tax Identification Number, known as the Codice Fiscale, is a unique alphanumeric code assigned to individuals and entities for identification in all dealings with public authorities and other administrations. Possessing the correct TIN is essential for individuals, businesses, and entities to ensure compliance with Italian tax regulations. All information presented in this guide is verified from official sources, including the Agenzia delle Entrate (Italian Revenue Agency) and other trusted government publications.
Tax Identification Number Types
Italy utilizes specific types of TINs for different categories:
- Codice Fiscale: Applicable to individuals (both residents and non-residents) and certain entities. It consists of 16 alphanumeric characters.
- Partita IVA: Assigned to businesses and self-employed individuals for Value Added Tax (VAT) purposes. It comprises 11 numeric digits.
These classifications are directly referenced from the official guidelines provided by the Agenzia delle Entrate.
TIN Format and Structure
Codice Fiscale (Individuals)
The Codice Fiscale follows this exact format: LLLLLL99L99L999L, where:
- LLLLLL: Three consonants from the surname followed by three consonants from the first name. If consonants are insufficient, vowels are used, and ‘X’ fills any remaining spaces.
- 99: Last two digits of the birth year.
- L: Letter representing the birth month (e.g., ‘A’ for January, ‘B’ for February).
- 99: Day of birth (for females, 40 is added to the actual day).
- L999: Four characters representing the place of birth (municipality code or foreign country code).
- L: Check character calculated from the preceding 15 characters.
This structure is meticulously outlined in the official documentation by the Agenzia delle Entrate.
Partita IVA (Businesses)
The Partita IVA consists of 11 numeric digits:
- Digits 1-7: Identifier of the taxpayer.
- Digits 8-10: Code of the office where the VAT number was issued.
- Digit 11: Check digit for validation.
The format and structure are specified by the Agenzia delle Entrate.
