How the DGT's position has evolved
Current position
The calculation of the period for the generation of the increase in value begins on the date the transferring entity acquired the property. In cases of mergers, spin-offs, or asset contributions, the calculation is not interrupted and the previous date subject to tax is used. Regarding the ITPAJD (Tax on Increases in the Value of Land), the exemption for social housing requires maintaining said condition, and is not applicable if the land has been declassified.
The DGT's position does not show a single doctrinal evolution, but rather addresses various technical aspects of the tax. The means of proof for the non-existence of capital gains have been specified, and it has been clarified that business reorganization operations do not interrupt the calculation of the period for the generation of the increase in value.
Turning points

-
Clarifies that in mergers, spin-offs, or asset contributions, the calculation of the period for the generation of the increase in value is not interrupted.
