Spain’s SII (Suministro Inmediato de Información) is a near real-time VAT reporting system introduced to modernise VAT control and reduce fraud by moving statutory VAT ledger books into a digital, quasi real-time environment. It was established via Royal Decree 596/2016 (published 2 December 2016), with a voluntary start on 1 January 2017 and mandatory application from 1 July 2017 for key taxpayer groups.

Under SII, businesses do not submit “e-invoices” for clearance; instead, they transmit invoice record data (VAT book entries) electronically to the Spanish Tax Agency (AEAT) using XML web services. Over time, reporting windows were tightened (from 8 days to 4 days), and additional ledgers and validations (e.g., consignment/call-off stock related reporting) were added to increase transactional transparency.

Mandate Details

Mandate Status

Which types of transactions must be reported via e-Invoicing?

Effective: Jan 2017

Live, but it is a VAT real-time reporting mandate (SII) rather than a clearance e-invoicing mandate.

Are there any thresholds that determine e-Invoicing applicability?

Yes (taxpayer-based, not invoice-value-based).

SII is mandatory for taxpayers with a monthly VAT settlement period, including:

Large companies (turnover > €6,010,121.04)
REDEME (Monthly VAT Refund Registry) taxpayers
VAT groups
Tax warehouse holders for gasoline/diesel/biofuels (from 01/01/2025)
Businesses voluntarily opting in

Do I need to have a permanent establishment in Spain to be required to e-invoice?

SII applies based on Spanish VAT position and inclusion in the SII taxpayer categories (monthly VAT settlement, REDEME, VAT groups, large companies, etc.), not strictly on having a permanent establishment.

Local suppliers / Spanish-established taxpayers: If within SII categories – must report.

Foreign suppliers registered for VAT in Spain: If they fall within SII categories – must report, even if non-resident.

Foreign suppliers without Spanish VAT obligations: Not in scope.

A “fixed establishment” is referenced under Spanish VAT rules (and EU Implementing Regulation 282/2011 concepts) for determining VAT presence, but SII obligation is triggered by being an SII taxpayer.

Do I need a VAT registration in Spain in order to apply for e-invoicing?

Yes, in practice SII is a VAT reporting obligation for taxpayers registered for VAT in Spain who meet the SII inclusion rules:

B2G / B2B / B2C / Cross-border: If the business is VAT-registered in Spain and is in scope for SII (monthly VAT settlement / REDEME / VAT group / large company / tax warehouse holder / opt-in) - SII reporting applies.

Foreign digital service providers: no specific exception stated for SII. If they are VAT-registered in Spain and fall within an SII category, they must report.

What is the prescribed deadline for submitting e-invoices?

Issued invoices: within 4 calendar days after issuance
Received invoices: within 4 calendar days after accounting entry (and always before the 16th of the following month)
EU transactions: within 4 calendar days from shipment/reception
Corrections: by the 16th of the month following the relevant return period

Invoices must generally be issued by the 16th of the month following the chargeable event (special rule for intra-community supplies of goods also by the 16th following dispatch/transport start)

Are there any penalties for non-compliance?

Yes. Surcharges apply based on supply price:

Omitted/inaccurate records: 1% of omitted/inaccurate amount, minimum €150, up to €6,000

Failure to submit/maintain books: 1% of turnover, minimum €600

Late filing: 0.5% of overdue invoice amount, minimum €300 per quarter, maximum €6,000

Steps to be performed by customer

1. Confirm whether the business is an SII taxpayer, such as a taxpayer with a monthly VAT settlement period, REDEME registration, VAT group status, large company status, relevant tax warehouse holder status, or voluntary opt-in.

Steps VAT IT can assist with

2. Obtain a valid electronic certificate accepted by AEAT for authenticated web service submissions.

3. Map internal invoicing data to the required SII VAT record books, including the Book of Issued Invoices, Book of Received Invoices, Book of Certain Intra-Community Transactions, and Book of Investment Goods.

4. Implement XML generation and transmission through AEAT web services, either directly, through an authorised representative, or through a service provider.

5. Set controls to meet the relevant SII reporting deadlines, including the four-calendar-day reporting windows and the applicable 16th-of-the-month cut-offs for issued invoices, received invoices, intra-EU transactions, corrections, and other relevant records.

6. Establish internal governance for corrections, amendments, removals, queries, and monitoring AEAT responses for accepted or rejected records.

In summary

eezi can assist by receiving transaction data from the client through API, flat files, or manual input on the eezi platform, transforming that data into the correct XML format, and transmitting it to AEAT for SII reporting.

eezi can support reporting for the Book of Invoices Issued, Book of Invoices Received, Book for Certain Intra-Community Transactions, and Book for Consignment of Goods, etc. eezi can also help clients amend, remove, and query reported invoices, and make AEAT responses available on the eezi platform for monitoring and follow-up.
