Spain Mandates Electronic Invoicing for Domestic B2B Transactions Starting July 2027

• Spain will require electronic invoicing for domestic B2B transactions, starting from a Royal Decree approved on March 24, 2026.
• Invoices must be in structured, machine-readable formats, with status updates reported to the AEAT public platform.
• Implementation is phased: large companies comply by July 2027, others by July 2028.
• The system uses interoperable private and public platforms, applies only to local B2B transactions, and exempts non-residents without a Spanish establishment.
• The reform targets fraud reduction, improved payment traceability, and alignment with EU digital VAT initiatives.
