How the DGT's position has evolved
Current position
The Regulation on computer billing systems (RSIF) applies to those carrying out economic activities and using systems that support billing processes. Producers and distributors must offer adapted products that guarantee the integrity, traceability, and unalterability of records. Taxpayers may opt for systems that comply with the regulations or the application of the Tax Administration. The RSIF does not apply if the issuance of invoices is manual or if the system is used exclusively for the issuance of tickets.
The DGT's position remains constant regarding the application of the RSIF to systems that support billing processes and to the producers of these systems. Rulings have progressively specified the scope of application, clarifying the situation of SaaS systems, scales, cash registers, and partnerships (comunidades de bienes). No changes in criterion are observed, but rather a technical delimitation of the obligated subjects and objects.
Turning points
-
Establishes the obligation of producers to offer systems with the capacity to send records to the AEAT and to allow VERI*FACTU functionality before July 2025.
-
Defines that scales are billing systems if they support such processes and establishes the mandatory requirement of a responsible declaration visible to the customer.
