How the DGT's position has evolved
Current position
The issuance of tax certificates is a management function that corresponds to the municipal tax administration. The certificate must be issued by the administration that has evidence of the facts intended to be certified. Specific competence lies with the municipal administrative body with express attribution or with the lower competent body by reason of the subject matter.
The sequence of rulings does not show a doctrinal evolution on a single concept, but rather addresses various aspects of tax management (proof of losses, self-assessment, regional competence, tax residence, and services). There is no change in position or a coherent thematic trajectory that allows for the establishment of a doctrinal evolution.
