SII module for SAP Business One

Módulo para SAP Business One para la gestión del IVA mediante el sistema SII de la EAT.

The Tax Agency has developed a new system called Immediate Information Supply (SII) for the management of VAT and VAT books for taxpayers presenting VAT on a monthly basis.

You can already manage VAT through the SII system of the AEAT.

Although it is mandatory from July 1, 2017 for taxpayers who submit the monthly VAT, the information must be presented in this new format from January 1, 2017.
SII module for SAP Business One

The SII system comes into force as of July 1, 2017. The main obligation for companies consists of the declaration to the Tax Agency of the detail of registration of the invoices issued and received, within a period of 4 calendar days from the date of invoicing, achieving in this way an approach between the date of accounting of the invoices with the effective realization of the operation. Specifically, the AEAT has extended this term to 8 calendar days during the year 2017.

The transmission of information must be done electronically using new digital formats of invoice books issued and received.

  • Record Book of Expedited Invoices
  • Record Book Received Invoices
  • Record Book of investment goods
  • Record Book of certain intracommunity operations

Main novelties of the SII system

  • The SII is mandatory as of July 1, 2017 for all taxpayers who file VAT monthly. It can also be adopted voluntarily for taxpayers who are not obligated.
  • The supply of information is done in the established electronic format and through the web service. The amount of information to be transmitted is much greater than that contained in the traditional registration books.
  • The period of electronic information is 4 calendar days from the date of issue of the sales invoice or the registration of the purchase invoice. During the year 2017 this plan is extended to 8 calendar days.
  • Other less common operations such as rectifications, cash or intra-community criteria, are allowed in terms longer than 4 days.
  • Although the entry into force of the SII system is on July 1, 2017, it is mandatory to present in this format the transactions carried out from January 1 to July 30, 2017 (available until January 1, 2018 for this).

This means that the IT systems of the affected taxpayers must be adapted to the SII from January 1, 2017 with the data structure and new required values.

The system of Immediate Supply of Information (SII), is the new model developed by the Tax Agency (AEAT) for the electronic declaration of VAT registration books.

SAP will release a patch to support the SII. Axalpha Consulting offers SII support independent of the release of the SAP patch, for clients.
