What is SII?

The SII (Immediate Supply of Information on VAT) requires the electronic communication of relevant data for VAT purposes of all invoices issued and received by the company, including simplified invoices or tickets, within a maximum period of 4 days.

Which companies are affected?

Over 62,000 companies throughout the country are required to adapt to the new SII system, including:

Large companies with annual turnover over 6 million euros.
Corporate groups for VAT purposes.
Registered in the REDEME or monthly tax refund system.

Those companies that voluntarily want to join this new VAT bookkeeping system can also adopt the SII.

When does it come into effect?

Any affected company must be operating with the new SII system from July 1, 2017. The starting date for the Tax Authorities is January 1, 2018.
