What is the Immediate Supply of VAT Information?

The Immediate Supply of VAT Information is the new system for the electronic management of VAT registration books that is done through the electronic headquarters of the AEAT.

In today’s post we explain one of the main changes that has taken place in the VAT management system: the Immediate Supply of Information (SII).

This system came into force on July 1, 2017 and was born to streamline the VAT management processes of companies.

We give you all the information you need about this system: what it is, who has to file the Immediate Supply of Information, what information it must include and when it is filed.

What are the objectives of the Immediate Supply of VAT Information?

The main objectives of the SII are:

  • Improve the quality of the information and data provided to the Tax Agency by taxpayers.
  • Fight against tax fraud through a better knowledge of each taxpayer’s data.
  • To save on costs derived from the traditional management of postal documents.
  • Improve information for accounting management.
  • Obtain more efficiency when dealing with the SII and for its management by both the Tax Agency and the users themselves.
  • Increase communication between the Tax Agency and the taxpayers themselves.


How does the VAT Immediate Supply of Information System work?

The SII was created to improve tax control and taxpayer assistance.

Entrepreneurs, professionals and all VAT taxpayers will have to manage their information through the AEAT’s electronic headquarters.

They will be able to carry out a real control of the taxation and thanks to it and to the electronic headquarters of the Tax Agency, taxpayers will be able to:

  • Register the invoices received
  • Execute a register book of invoices issued.
  • Prepare a register book of investment goods
  • Control the register book of intracommunity operations.

These books will be created by recording the information sent to the system. For example, each time an invoice is issued or received, it will also be sent to the Tax Agency. Each invoice will be sent twice: to the issuer and to the receiver.

In this way, data can be crossed and a more exhaustive control can be carried out. Taxpayers will also have access to the record books available at the Tax Agency.


Who is obligated to the SII?

The Immediate Provision of Information is mandatory for:

  • Companies registered in the REDEME (VAT Monthly Return Register).
  • Large companies with a turnover exceeding 6.010.121,04€.
  • Taxpayers that are under the regime of groups of entities.

It should be noted that there are companies that voluntarily apply for this system by filing a census return using form 036.

Although there is a deadline to opt for the electronic handling of the registry books by means of the SII for all those companies that want to do it voluntarily, they can do it at any time of the year.
