What is the Immediate Supply of Information (SII)?

The Spanish Tax Agency introduced a new VAT management system based on Immediate Supply of Information (SII).
The taxpayer must send billing data from VAT Books electronically to the Tax Agency within four calendar days:
-Using web services based on exchanging XML messages or
-If applicable, by filling out the online form.

Do you have to send invoices to the Tax Agency?

No, taxpayers are not required to send the actual bills. What has to be sent are the invoice record fields specified in the corresponding Ministerial Order.

Using these data, the different Record Books will be configured practically in real-time.

Record Books on the online system include:
- Register Book of Issued invoices.
- Register Book of Received invoices.
- Register Book of Investment goods.
- Register Book of Specific Intra-Community operations.

Does the Immediate Supply of Information (SII) affect all VAT taxpayers?

Since 2017, use of the SII is compulsory for taxpayers who are subject to self-assessment of VAT on a monthly basis:
-Large Businesses (turnover of over 6 million euros)

-VAT Groups
-Registered with REDEME (Monthly VAT Return Registry)
The new SII can be applied to all other taxpayers who choose to opt-in voluntarily.
