How the DGT's position has evolved
Current position
The Regulation on computerised invoicing systems (RSIF) applies to taxable persons who carry out economic activities through computer systems. The manual issuance of invoices is excluded, but the use of spreadsheets, databases, or processors may trigger the obligation to comply with the Regulation. Taxpayers may use systems that comply with the regulations or the Tax Agency's application.
The DGT's position has shifted from addressing the declaration of VAT (IVA) operations to focusing on the scope of application of the RSIF. Current doctrine specifies that the use of tools such as spreadsheets may trigger the obligation under the Regulation. Likewise, it is clarified that for Personal Income Tax (IRPF) taxpayers, the obligation only arises if there is a real economic activity, as occurs in the leasing of real estate with employed personnel.
Turning points
-
Specifies that the use of spreadsheets, databases, or processors may be considered a computerised invoicing system, triggering the obligation under the Regulation.
-
Links the application of the RSIF to the existence of economic activity for IRPF, noting that the leasing of real estate without salaried personnel does not constitute economic activity for this purpose.
