Here we tell you all about the IBS and the advantages of using eFacturaLink to automatically send your invoices

What is the SII and for which companies is it mandatory?

The Immediate Supply of VAT Information (SII) is a system implemented by the Spanish Tax Agency for VAT management. This system obliges businesses to send electronically the details of their invoicing records, both invoices issued and received, via the Electronic Headquarters of the Tax Agency. The IBS updates the VAT Register Books electronically and almost in real time, allowing the Tax Agency to have a more accurate and up-to-date view of companies' economic operations.

Companies obliged to use the SII

Undertakings obliged to use the IBS, Immediate Provision of Informationare those that:

  • They have an annual turnover of more than 6 million euros.
  • They are registered under the monthly VAT refund scheme.
  • They are VAT groups.

It can also be used by any company that chooses to do so voluntarily. It is an option to VERIFACTU, which becomes compulsory for all other businesses from 1 January 2026. However, SII involves sending all invoices, both issued and received, to the tax authority and submitting VAT monthly, whereas with VERIFACTU, we only have to send invoices issued to customers and VAT submission remains quarterly.

Deadlines for sending invoices to the SII

Companies obliged to use the SII must send the billing records in a period of four calendar days from the issue or receipt of the invoice. This period is extended to eight days for invoices issued by the recipient or by a third party.

Advantages of using IBS

  • Reduction of formal obligationsCompanies do not have to file forms 347, 340 and 390.
  • Increased control and attendanceThe Tax Agency can cross-reference data more efficiently, which improves tax control and makes it possible to offer services such as Pre303, for the automatic preparation of VAT self-assessments.
  • Transparency and securityThe near real-time information reduces the risk of errors and fraud.

What is Verifactu and differences with SII

VeriFactu it is the new system of verifiable billing required by the Anti-Fraud Law: Royal Decree 1007/2023 and the regulations of Law 11/2021 on measures for the prevention and combat of tax fraud.

Next-Step eFacturaLink-automatic sending of invoices to SII

Advantages of eFacturaLink

The implementation of eFacturaLink for the automatic sending of information to the SII offers you many advantages:

  • Efficiency and Time Saving: Automation with eFacturaLink allows businesses to save valuable time and resources. By integrating accounting and invoicing systems with the IBS, the data is automatically extracted and sent to the HMRC quickly and accurately. This removes the need to manually collect information and fill out forms, reducing the administrative burden and allowing employees to focus on more strategic tasks.
  • Greater Visibility and Total Control: With eFacturaLink businesses gain greater visibility and control over their tax transactions. You will have total visibility and control over the invoices sent and the status of each one of them: Accepted, rejected, details of the error, if there is one... eFacturaLink provides detailed customised reports and real-time analysis, enabling decision-makers to make informed decisions based on accurate data.

  • Automatic, error-free compliance: When using eFacturaLink minimises human error and reduces the risk of non-compliance with delivery or deadlines, ensuring that your company is always up to date with its tax obligations.

eFacturaLink is not an invoicing software, but a connector between the software used by the company to generate invoices and the State Tax Agency's SII module, therefore it does not have to comply with the anti-fraud law requirements. However, eFacturaLink is compatible with Verifactu ERPs and invoicing systems.

Conclusion

The automation of sending invoices to the SII with eFacturaLink not only ensures and simplifies compliance, but also improves operational efficiency and provides greater control over tax transactions.
