Spain Sets Timeline for Mandatory Private Sector eInvoicing and VERIFACTU Compliance

Spain is mandating eInvoicing in the private sector to reduce VAT fraud, with detailed technical and security requirements.
The VERIFACTU protocol becomes mandatory for software vendors from July 30, 2025, and for taxpayers from January 1, 2026.
Large enterprises must comply by 2027 at the earliest, SMEs by 2028, with a 12-month notice period after the Ministerial Order.
eInvoices must include electronic signatures, QR codes, and use EN 16931-compliant formats (CII, UBL, EDIFACT).
Businesses should prepare by updating software, ensuring interoperability, and monitoring for regulatory updates.
