Immediate Supply of Information (SII)

The best solution to comply with VAT online

Connect with the Treasury to comply with the SII

The Immediate Supply of Information (SII) is a new system for keeping VAT registration books and the IGIC that is carried out through the Electronic Headquarters of the Treasury. It entered into force on July 1, 2017 for the AEAT, on January 1, 2018 for the Regional Treasury and on January 1, 2019 for the Canary Tax Agency.

The SII obliges companies to declare and send electronically to the Platform provided by the Treasury the detail of the invoices 4 days after they have been issued or accounted for if they are received, bringing the invoice registration time closer to the effective realization of the invoices. The economic operation.

At ZeroComa we have developed a solution, EdasSII, which, with about 1,000 users, is one of the most prominent and used for the management of IBS. EdasSII is compatible with the SII of the AEAT, the SII of the Haciendas Forales and the SII of the Canary Islands.

The Tax Agency implements a new system of keeping accounting for the products subject to Special Taxes (SILICIE), in accordance with Article 50 of the Special Tax Regulation. From January 1, 2020, the obligation of keeping the accounting of the products subject to Special Taxes, and where appropriate, the raw materials used in obtaining them, will be carried out through the electronic Headquarters of the Tax Agency, by electronic supply of accounting entries.
