Organizations operating in the Basque region of Spain will soon be required to comply with SII reporting requirements. As reported in this forum, effective July 1 most companies operating in Spain are now required to transmit information to the Spanish Tax Administration (AEAT) regarding purchase and sale transactions within a few days of invoicing. Today, these requirements do not apply in the Canary Islands, Ceuta, Melilla, Navarra and the Basque regions (which include Alava, Guipúzcoa and Vizcaya). With respect to Navarra and the Basque Regions, the reason the requirement does not apply is due to the special relationship these locations have with the federal government whereby VAT is collected and remitted under a parallel but separate system.
Over the last several days, the Basque Regions and Navarra have announced that they will implement the SII starting January 1, 2018, While the rules will be similar to standard Spanish SII, administration will handled through local authorities and not AEAT. We expect additional regulation and technical specifications to follow shortly.
