In August 2026 the government expanded on Royal Decree 238/2026, publishing a step‑by‑step guide that tells firms how to configure invoicing software, register client details, generate Facturae/UBL/CII files, transmit them through approved channels and retain records for the statutory period. The guidance reinforces the October 2027 deadline for larger companies and the earlier 1 January 2027 start for corporate taxpayers.

A few days later, the Council General of the Colleges of Administrative Managers appealed for a more SME‑tailored approach. It warned that the uniform deadlines – 1 January 2027 for corporations and 1 July 2027 for self‑employed – could impose disproportionate technological burdens on micro‑enterprises and freelancers. The council urged proportional criteria, selective exemptions and risk‑based measures while still supporting digitalisation and AI‑enhanced tax control.

Together with the earlier postponement and the decree, these developments highlight both the operational steps required for compliance and the ongoing debate over proportionality for Spain’s small‑business sector as the Verifactu system becomes mandatory.
