Tax Authorities start sending letters about Spanish SII reconciliations

Tax Authorities have already started sending communications to taxpayers required to submit information through the Spanish SII system, the real-time VAT reporting obligation in Spain.

1 December, 2017


Spanish SII submission notification

The purpose of these communications is to warn businesses about the discrepancies found between the VAT returns and Spanish SII reports submitted, as well as highlight the importance of meeting these compliance obligations to avoid possible penalties (reporting period, information provided, content data requirements, etc).

How is this impacting your VAT obligations?

In principle, these letters are only informative so that the data reported in the VAT return is still considered as final. However, it is expected that penalties will start applying in the coming months in connection with these discrepancies and potential gaps in the information reported.

Until this moment, the Spanish tax authorities have taken a flexible approach on the application of penalties regarding the delay in the obligation to report electronically all invoices within the reporting period stated by the SII rules, which will decrease from eight days to four days as from 1 January 2018.

Nevertheless, it seems likely that penalties will apply to those taxpayers who are not complying with the formal requirements or whose reports do not match with the information submitted on the VAT return. That is why when preparing the VAT return, we recommend checking all SII data and reconciling it with the amounts reported in the return so that if there are any differences these can be resolved before sending the data to the Tax Authorities.
