How the DGT's position has evolved
Current position
The contribution of separate property to a community property regime constitutes an alteration in the composition of the contributor's assets. This operation generates a capital gain or loss for half of the asset (the 50% that passes to the non-contributing spouse). The transfer value must be the reference or market value, without the possibility of reducing it by the existing mortgage debt.
The DGT's position has remained constant since 2014. All rulings confirm that the contribution of separate property to community property is an asset alteration that requires taxation on the half transferred. No changes are observed in the interpretation of the nature of the operation or in the determination of the taxpayers.
