How the DGT's position has evolved
Current position
The grouping of estates is a registry reorganization that does not alter the ownership or the physical nature of the dwelling. It does not interrupt the calculation of the effective residence period for exemptions in IRPF (Personal Income Tax), as it is considered acquired on the date of the original ownership of the undivided shares. These operations are taxed under the Documented Legal Acts modality, as they do not constitute an onerous transfer of assets.
The DGT's position has remained constant over time. It is confirmed that grouping is not a transfer of assets, but rather a physical or registry alteration that is taxed under Documented Legal Acts. Recent rulings reinforce the continuity of the acquisition date and the non-interruption of residence periods for exemptions.
Turning points
-
Establishes that grouping, horizontal division, and adjudication are taxed independently under the Documented Legal Acts modality when no prior undivided ownership exists.
-
Specifies that grouping does not interrupt the calculation of the three-year effective residence period for the IRPF exemption.
