How the DGT's position has evolved

Refined position High confidence 35 rulings · 2014–2025

Current position

The acquisition date for calculating the period of generation of the increase in value is the date the transmitting entity acquired the property. In merger or asset contribution processes, the calculation is not interrupted, and the previous date subject to tax is used. For assets transitioning from public domain to private property, the acquisition date is the date of the transfer from the public domain.

The DGT's position has transitioned from defining the nature of de-dedication in community property and its impact on IRPF (Personal Income Tax), towards the technical determination of the acquisition date for calculating the generation period in the IIVTNU (Tax on Increased Value of Urban Land). The most recent rulings focus on the continuity of the temporal calculation in corporate operations and the transition of assets from the public domain.
