Relationship Between Tax Code and CIE
The Electronic ID Card (CIE) and Tax Code (Codice Fiscale) are two fundamental Italian identity documents, closely connected to each other.
The modern CIE integrates the Tax Code in its NFC chip, allowing unique citizen identification for both registry and tax purposes.
- The Tax Code is printed on the front of the CIE
- The Tax Code is stored in the card's NFC chip
- Both documents are linked in the National Registry
