What is the Portuguese e-Fatura invoice reporting system?

Effective: 2013-01-01 · Authority: AT (Autoridade Tributaria e Aduaneira)

e-Fatura is the Portuguese real-time invoice reporting system where businesses communicate invoice data to the AT within 5 working days of issuance. It enables the AT to pre-fill individual taxpayers' annual income tax returns and monitor VAT compliance. The system covers both B2B and B2C transactions.

How does e-Fatura enable consumer tax deductions?

Portuguese consumers can claim tax deductions on invoices submitted to the e-Fatura system that include their fiscal number (NIF). The AT pre-populates consumer income tax returns with deductible expenses from validated e-Fatura invoices. This creates a powerful incentive for consumers to request invoices with their NIF.
