Royal Decree HAC/27/2026 replaces Annex I of Royal Decree EHA/3111/2009 regulating IVA annual summary form 390 with updated technical specifications. Affected taxpayers must update their submission processes from the date of entry into force. The new version establishes updated technical specifications for maintaining IVA registers via the Tax Agency's electronic portal (art. 2).
VAT-registered businesses must migrate to new digital registration models on the electronic platform within three months of entry into force. Non-compliance may result in fines of up to €1,500. Tax authorities' functions remain unchanged, only the digital formats are updated.
