Even if the SII reporting was implemented only in 1 July 2017, the Spanish authorities require all taxpayers to submit SII data from the first semester of the year.
There are specific data requirements aimed at making things easier for taxpayers. There are also exceptions for certain companies and some data that is still required under the current format. The complication here comes for businesses who adapted their systems only as from 1 July 2017, as they will not be able to produce the SII files for periods before the implementation date. In these cases, you can convert your book of invoices issued and received into a template that can be converted into the XML required by the authorities. Please send us an email if you want to receive this template.
When evaluating the need to submit your SII electronic books for the first semester, you must take the following remarks into account:
We recommend sending your data as early as possible to avoid doubling the work with the end of the year obligations. SII reporting will also require some extra data as part of your last files submitted at the end of each year.
The authorities are requesting this information via SII because you will no longer be required to submit the Annual VAT return (Modelo 390) and Annual Sales and Purchases Listing (Modelo 347). As these are annual VAT returns and the SII was only introduced in July, it will be mandatory to provide information for the first semester.
Regarding SII data requirements, the authorities have simplified the requirements by reducing the number of codes and distinctions between transactions:
There is more information about content requirements in the tax authorities website (in English).
We created a simple template where you can copy and paste your book of invoices issued and received. We will then convert this template into a CSV that is uploaded in our platform, converted into XML and sent via webservice to the Spanish tax authorities. You will receive a confirmation of all reported amounts with the status for each line.
Please send us an email if you want to receive this template to evaluate how it adapts to your current books of invoices.
