What does SII means and what it implies?
SII is the new system of information supply to the Spanish Tax Agency. It is an electronic process made to improve the distribution of the VAT registration company books to the Tax agency.
This new process focuses on implementing the duty of stating all the invoices received and sent by the company electronically. With the new system, companies will be able to communicate immediately with the agency. There will be no need to declare the 340,347 and 390 forms anymore. Also, companies will now have the requirement to send all this information within 4 days, 8 if you hire an external service supplier like Docuten.

- Companies enrolled in the monthly return program (REDEME).

When does it come into effect?
The SII will enter force this coming 1st of July of 2017. More than 62.000 Spanish companies will be under the requirement to enroll in the new process.
How does the SII works?
Companies used to register their invoices through the 340, 347 and 390 printed forms. From now on, this registration will be made through telematic and immediate invoice with the Spanish Tax Agency.With the SII, companies will send more frequent information. Specifically, they will need to register the following VAT information:
- Sent Invoices
- Received Invoices
- Investment goods
- Intra-community transactions
- Cash Amount registration book
The Spanish tax agency had defined a specific XML format for this information exchange. Docuten, Enxendra’s new platform contacts automatically with the Tax agency system to send the information needed. Moreover, the agency will send back the status , totally acknowledging the delivery, partially confirming the information or totally denying the data provided.
