According to R.D. 596/2016 in Spain, a new value-added tax (VAT) management system that is based on the Immediate Supply of Information on VAT (Suministro Inmediato de Información del IVA [SII]) allows for a two-way, automated relationship between the Spanish Tax Agency (La Agencia Estatal de Administración Tributaria [AEAT]) and the taxpayer. Starting July 1, 2017, taxpayers who are subject to SII, and others who voluntarily adopt it must send details of their billing records within four days through online filing on the AEAT website.
SII setup is the same as Standard Microsoft SII Setup with following considerations:
- Comm. Transact. When Posting field must be selected for on-line communication (SII communication is launched for each transaction posting).
- SII on Statement Posting field must be selected for off-line communication (SII communication is launched on Statement Posting).
Additionally, in SII communication, there are 2 ways to send refund information:
- S (Substitution): Rectification amount is sent to authorities.
- I (By differences): Rectification amount is not sent to authorities, just the data of the refund document.
Both options (substitution and by differences) are legal and can be sent. For LS SII, refunds are always sent as I (by differences) option. The reason for this is because the solution is based on how Microsoft Standard is creating XML file and substitution option is not always correctly solved.
All the communications sent to Tax Authorities are for sales posted in LS POS (sales & prepayments).
Purchase invoices must be sent from back-office.
