How the DGT's position has evolved
Current position
The exchange of shares between co-owners is classified as an onerous transfer of assets subject to the IIVTNU (Transfer Tax and Duties on Property Transfers). Each co-owner pays tax on the acquisition of the received share at the real value of the real estate assets. For IRPF (Personal Income Tax), the operation does not generate a gain or loss if the adjudication strictly respects the ownership share of each party.
The DGT's position has remained constant since 2014. The doctrine establishes that if the adjudication of assets does not dissolve the community but instead exchanges interests, the operation is an exchange of shares and not a mere transformation of rights. The most recent rulings maintain this criterion and specify the treatment for IRPF in the event of excess adjudication.
