What is changing?
Spain’s Tax Agency, AEAT, announced G5v2 technical guide version 2.12 on 9 September 2026. It changes how discrepancies between G5G notifications are managed when goods move under temporary customs storage.
Who needs to check?
The practical relevance is mainly to carriers, customs agents and operators handling these movements in Spain. Where your delivery route uses this process, ask the carrier or broker whether its systems are ready for 22 September.
Messaging problems could affect processing, but AEAT’s notice does not report an existing disruption.
What does this mean for sellers?
The announcement does not introduce a new seller data field or announce changes to VAT, IOSS, the €3 low-value duty or parcel-value thresholds. Continue providing accurate shipment information; do not change prices or customer declarations solely because of this technical notice.
