VAT codes and fiscal mapping
Use the appropriate sales or purchase tax codes and available fiscal mappings so documents, electronic invoices and VAT reports share a coherent tax classification.
A tax code means more than a percentage
Two lines can have the same numeric tax rate and different fiscal meanings. Exemption nature, sales or purchase use, reverse-charge treatment and supported local classifications affect how the document is transmitted and reported. Choose the relevant fiscal code rather than selecting a zero-rate entry simply because no VAT amount should appear.
Keep setup and source-document mapping aligned
Available fiscal packages provide country-specific reference content for supported configurations. Document processing and integrations must map their source tax facts to the intended codes. Review those rules with the accountant before automation, and inspect exceptions where the incoming document lacks the evidence needed for a reliable classification.
What to know before you start
A code catalogue is not tax advice. Confirm the correct treatment for the transaction; matching only the percentage can still produce the wrong electronic invoice or register classification.
Practical questions
Are all zero-rate codes interchangeable?
No. Exemption, exclusion and reverse-charge classifications have different meanings even when the numeric rate is zero.
Can source integrations use their own mappings?
Supported customer rules define the mapping. Review the selected target codes and preserve the distinction between different tax treatments.
Continue the workflow
VAT registers
Inspect supported sales, purchases, reverse-charge, receipts and OSS registers with period filters, tax detail and the available legal-format exports.
Electronic invoicing
Use supported Italian electronic-invoice sending and receiving workflows, with fiscal references, transmission outcomes and linked accounting documents.
Non-deductible VAT treatment
Use the supported Italian non-deductible VAT configuration and fiscal codes to distinguish the deductible and non-deductible treatment of purchases.
