How the DGT's position has evolved
Current position
The invoice must contain a description of the services with sufficient detail to determine their nature, amount, and tax rate, without needing to be exhaustive. If the description allows the operation to be verified and includes a reference to the exemption, a corrective invoice is not mandatory. The obligation to rectify only arises when the original invoice lacks essential data.
The DGT's position remains stable regarding the validity of documents, provided they comply with the mandatory mentions of the Invoicing Regulations. It has been specified that the description of services does not need to be exhaustive if it allows for the identification of the nature and the tax rate of the operation. No fundamental changes are observed regarding the requirement for correlativity and minimum content.
