How the DGT's position has evolved
Current position
Taxpayers using computerized systems for billing must comply with Royal Decree 1007/2023 (RSIF), with the option to use the Administration's application or a certified proprietary system. The RSIF does not apply to the manual issuance of invoices, the issuance of tickets, or to taxpayers subject to the SII (Immediate Supply of Information). Spreadsheets or databases may be considered computerized billing systems if they support such processes.
The DGT's position remains constant regarding the application of the RSIF to those using computerized means, allowing the choice between proprietary software or that of the Administration. The cases of exclusion have been specified, such as manual billing, the issuance of tickets, or being a subject of the SII. The doctrine confirms that tools such as spreadsheets can trigger the obligation if they act as billing systems.
Turning points
-
Establishes that the enforceability of the RSIF and the infringement for non-certified systems will only operate from January or July 2027.
-
Clarifies that if the system is used solely to issue tickets, it falls outside the scope of the RSIF.
