How the DGT's position has evolved
Current position
Under the equivalence surcharge regime, there is no general obligation to issue an invoice, unless the recipient is an entrepreneur or professional or it is required for the exercise of tax rights. When there is an obligation to issue an invoice, the computer systems used must comply with the technical requirements of the Regulation on computer or electronic systems and programs that support billing processes (RSIF). Operations excepted from the obligation to invoice are excluded from the objective scope of said Regulation.
The DGT's position remains constant regarding the distinction between the obligation to invoice and the application of the Computer Systems Regulation. Recent rulings clarify that the lack of an obligation to issue an invoice exempts compliance with the technical requirements of the RSIF. It is confirmed that the equivalence surcharge regime limits the issuance of invoices to specific cases involving entrepreneur or professional recipients.
Turning points

Clarifies that the billing computer systems regulation does not apply to those in the equivalence surcharge regime when there is no obligation to issue an invoice.

Establishes that operations excepted from the obligation to invoice according to the ROF are excluded from the objective scope of the Regulation on computer and electronic systems and programs (RSIF).
