Reliable and timely communication with Spanish tax authorities.

What are REDEME and SII registration?

The REDEME (which stands for “Régimen de Devolución Mensual”) is a monthly refund system whose purpose is to obtain the input VAT of the investments made as soon as possible. As a consequence of using this system, you will also have to submit to the SII (which stands for “Sistema de Información Inmediato”) which is based on the keeping of the tax registry books through the Spanish Tax Agency electronic office by means of the quasi immediate supply of the invoicing records of your company.

This REDEME regime is mandatory for companies with an annual turnover of more than 6 million euros and it is also very interesting for companies that import goods to Spanish territory (operation subject to VAT) and sell them to other countries of the European Union (VAT exempt operations) so they accumulate large amounts of input VAT.

How can Accounting Services help your business?

Those registered in the REDEME must declare VAT returns every month (between the 1st and the 30th of the following month) by filing form 303.

The VAT refund becomes effective during the month following the settlement period. This means that, in order to recover the VAT for January, for example, the registered person has to wait at least until March, once the liquidation period has passed (from February 1 to 30).

The refund is always made by bank transfer, in the bank account indicated by the company in its VAT return.


These systems require fast and continuous communication with the Spanish Tax Agency, so a consultant will allow you to comply with all the necessary requirements of this system and will release you from the responsibility of all this process of electronic communication with the Spanish Tax Agency. The client’s only function is to deliver on time the documentation (invoices received, invoices issued, bank statements and any other documentation that may be important for the client) related to the company.


Another benefit of having experts in the field is to avoid possible penalties for poor compliance with the requirements of this system.

What is included in our service?

  • Reduction of formal obligations, eliminating the obligation to file other informative forms.
  • When two companies are in REDEME and in the SII, the Spanish Tax Agency is able to cross-reference the data of the operations between them and therefore the number of Requests received by the Tax Authorities is reduced.
  • Reduction of the time required to carry out the refunds, since the Spanish Tax Agency will have the information in almost real-time and more information on the operations.
