SILICIE (Suministro Inmediato de Libros Contables de Impuestos Especiales – ‘Immediate Provision of Special Taxation Account Books’) is a project set in motion by the Tax Agency (AEAT – Agencia Estatal de Administración Tributaria) that will modify the accounting system of establishments affected by Article 50 of the Special Taxation Regulation.
The compulsory entry into force of SILICIE will occur on January 1, 2020, and from that date forward, accounting for products affected by this article will have to be conducted using a software format directly from the website of the Tax Agency.
Who is affected by the new legislation?
All companies that store, transport, manufacture or sell products subject to special taxes:

The alcohol and alcoholic beverages group

The hydrocarbon group

The tobacco work group

The mixed group: alcohol and tobacco work
Modifications that will come with SILICIE
This legislation will have a major impact on the information that will have to be reported to the Treasury:
- With respect to operations and transactions, it increases the level of detail to be submitted.
- With respect to deadlines, it reduces the time available for reporting, leaving a maximum of 4 days from the date of a transaction.
- Establishments shall be provided with a structured format for online submission of information to the AEAT.
- Extraction of the information may be complex, since it increases the number of fields and the level of detail within them. It is possible that not all of the information is currently to be found in the system, which will make it necessary to revise available information on production, logistics and external interfaces.
