The SII has been mandatory since July 1, 2017, for taxpayers currently required to file VAT returns on a monthly basis (around 63,000 entities), including:
- Large companies (annual turnover over 6 million euros).
- VAT groups.
- Registered in REDEME (Monthly VAT Refund Scheme).
- Taxpayers who voluntarily choose to adopt the new system.
Yes. There will be an option to join the system for those taxpayers who wish to benefit from its advantages, even if they do not meet the mandatory requirements.
The main obligation is that companies must submit their billing records, as well as the declaration of other operations, electronically and immediately through the AEAT’s Electronic Headquarters.
You will need to check whether you are required to manage your VAT record books electronically. If so, keep your accounting up to date and ensure your invoices are properly recorded with reliable accounting software. Additionally, it is advisable to get trained in advance to fully understand this new telematic VAT management system.
Keep in mind that the SII will maintain a repository of record books to instantly match incoming and outgoing invoice data (Forms 340, 347, and 390). Data verification will be faster, as the Tax Agency will receive the information in real time. You’ll save time by no longer needing to manually maintain VAT record books, since the AEAT will update them automatically with the data provided by the taxpayer. Additionally, there will be fewer errors, as the AEAT will generate a sort of "VAT draft" based on this information for companies.
