Understanding the FatturaPA Format
An electronic invoice in Italy, known as a FatturaPA, is a structured XML document that businesses must use for nearly all transactions, including B2B, B2C, and B2G. This system, managed by the Italian tax authority (Agenzia delle Entrate) through the Sistema di Interscambio (SdI), aims to combat tax evasion, streamline processes, and enhance transparency in financial transactions.
The FatturaPA format is the mandatory XML structure for electronic invoices in Italy, ensuring uniformity and compliance across all business and public administration transactions. This structured XML format is crucial because it allows for automatic and electronic processing by both the SdI and the recipient's systems.
- Mandatory Fields: These fields are essential for the legal validity of the invoice and for tax compliance. They encompass details such as the issue date, a unique sequential invoice identifier, the business name and address of both the seller and buyer, the seller's VAT number, and the buyer's VAT number or tax code. For B2C transactions, if a buyer's fiscal code is unavailable, a placeholder code "0000000" is used. Additionally, specific VAT details, descriptions of goods and services, and a reference to applicable Italian/EU legal provisions for VAT exemptions are required.
- Practical Implications: The strict adherence to these fields ensures that the invoice can be validated by the SdI. Incorrect or missing information will lead to rejection, meaning the invoice is not legally recognized until corrected and resubmitted. This directly impacts payment processing and VAT deductions.
- Importance of Electronic Signatures: While not always mandatory for B2B transactions, a qualified digital signature is often required for B2G (Business-to-Government) invoices to guarantee authenticity and integrity. For long-term digital archiving, which is mandatory for 10 years, invoices must be digitally signed and time-stamped to ensure their legal validity and non-repudiation.
