How the DGT's position has evolved
Current position
The tax base in onerous transfers is the real value of the asset, a concept similar to the normal market value, which does not necessarily coincide with the agreed price. The Administration has discretion to choose methods for verifying values, although the valuation by the Autonomous Community is only binding for said entity. In a contradictory expert appraisal, the comparison must be strictly limited to the assets and rights included in the tax return.
The DGT's position remains constant in defining the tax base as the real or market value. Throughout the rulings, procedural aspects such as the scope of application of the expert comparison and the deadlines for the contradictory appraisal have been specified. No change in criterion is observed, but rather an application of rules in different scenarios.
