How the DGT's position has evolved
Current position
The tax census declaration is the instrument for registrations, cancellations, variations, and choices of tax regimes. Legal entities must request their NIF before conducting operations, on a provisional basis until documentation is provided. The revocation of the waiver of the objective estimation method mandatorily requires the submission of the census declaration form, without admitting tacit revocation.
The DGT's position remains stable regarding the nature of the tax census declaration as a tool for managing obligations. The rulings do not show a change in doctrine, but rather address specific aspects such as the mandatory use of specific forms (036 or 037), NIF management, and the necessary formality for the revocation of objective estimation regimes.
Turning points
-
Establishes that the revocation of the waiver of the objective estimation method must be express through a tax census declaration, ruling out the possibility of tacit revocation.
