Immediate Supply of VAT Information (SII)

The Immediate Supply of Information (SII) is the VAT processing system developed by the Tax Agency (AEAT). Tax Agency (AEAT) to electronically manage the Value Added Tax record books.

By means of the SII, companies provide information on their invoicing through the Electronic Headquarters of the Tax Agency and they do so within four days, which can be extended to eight days for companies where the invoices are issued by a third party.

Purpose of the SII

The SII or Immediate Supply of Information came into operation in 2017 to improve the traceability of companies' taxation. Specifically, it aims to to streamline and digitize the management of VAT and at the same time combat tax fraud throughout the business fabric. At the same time, the traditional VAT registration books seem to be tending to disappear.

At present, the SII is an obligation for organizations that are obliged to organizations that are obliged to self-assess VAT on a monthly basis. That is, any company belonging to one of these groups:

  • Large companies with a turnover of more than 6 million euros.
  • Organizations registered in VAT groups.
  • Companies registered in the VAT Monthly Return System (REDEME).
  • Any company that voluntarily joins this new VAT management system.

Moreover, the near future points to the fact that every business will have to adapt to systems such as the SII. Therefore, taking that step towards digital transformation will be a necessity as well as an advantage.
