How the DGT's position has evolved
Current position
For the entry of data in invoices and register books, the first and last names appearing on valid official identity documents should preferably be used. In the case of foreigners, the name appearing in their passport or identity document issued by their authorities shall be used. In cases of reverse charge, the recipient records the invoice in the received invoices book without the need to issue a self-invoice or record it in the issued invoices book.
The DGT's position remains stable regarding the possibility of making summary entries in the issued invoices book under specific requirements concerning date and recipient. The doctrine has progressively specified operational aspects, such as deadlines for SII (Immediate Supply Information System) taxpayers and the identification of recipients through official documents. No fundamental changes in the obligation to maintain these books have been observed.
Turning points
-
Allows the substitution of individualized entries with summary entries in the issued invoices book if the identification of the recipient is not mandatory and the accrual occurs within the same calendar month.
-
Establishes that the entry of the recipient's name must preferentially comply with valid official identity documents.
