BMC's client environment, included in your engagement: never sold separately.
A taxpayer married under the community property regime seeks clarification on the taxation of the free contribution of separate property to the community estate. The Directorate General of Taxes (DGT) rules that this does not trigger taxation via gift tax or onerous transfers, but it does have tax implications for the contributor's Personal Income Tax (IRPF).
Taxation of said contributions in Personal Income Tax, in Inheritance and Gift Tax, and taxation of the contribution of the real estate in the Tax on the Increase in the Value of Urban Land.
The community property regime, being a separate estate without legal personality, is not a taxpayer for Inheritance and Gift Tax. In Personal Income Tax, ownership of assets is attributed equally to each spouse; therefore, the contribution of a separate asset constitutes a change in the contributor's assets. This generates a capital gain or loss for half of the contributed asset, calculated according to the rules for lucrative transfers.
