The Spanish tax administration published yesterday all the technical documentation required for the implementation of version 1.1 of the Immediate Supply of Information system, locally known as SII. This new version 1.1 will be effective July 1, 2018, and is intended to correct several problems that have been spotted during the first seven months of implementation of the SII. The new version also introduces changes intended to facilitate taxpayer compliance. Version 1.1 of the SII is regulated by an order that still has not been formally enacted. For more information, the above mentioned Project of Resolution can be found on the AEAT site.
