VeriFactu: Spain's New Invoice Verification System

Starting in 2026, businesses in Spain must comply with VeriFactu, a new regulation designed to combat tax fraud. The system requires invoicing software to add a QR code to each invoice that allows anyone to verify with the Spanish tax authorities (AEAT) that the invoice was properly reported. This ensures transparency and prevents invoice manipulation. Legal entities must comply by January 2026, while sole traders have until July 2026. Any business operating in Spain that doesn't already use the SII (Immediate Supply of Information) system will need compliant invoicing software by these deadlines.
