How the DGT's position has evolved
Current position
Businesses must issue full invoices when the amount exceeds 400 euros or when the recipient is a professional established outside the tax territory. Exchanging a simplified invoice for a full one is possible and is not considered a corrective invoice if the original complied with the requirements of Article 7.1. The period for claiming the issuance of a full invoice is the four-year period to exercise the right to deduction. If computer systems are used for invoicing, compliance with the RSIF (Reglamento de Expedición de Facturas) is mandatory.
The DGT's position remains constant regarding the possibility of exchanging simplified invoices for full ones and the four-year period for claiming their issuance. The doctrine has specified the obligation to issue a full invoice for electronic services provided to professionals outside the national territory. Likewise, the application of the RSIF has been clarified based on whether invoicing is manual or through computer systems.
Turning points
-
Establishes the obligation to issue a full invoice, rather than a simplified one, when the recipient is a professional established outside the tax territory.
-
Determines that compliance with the RSIF is mandatory only if a computer system or program is used for invoicing processes.
