How the DGT's position has evolved
Current position
The taxable event for IBI (Real Estate Tax) is constituted by the ownership of specific rights such as administrative concessions, surface rights, usufruct, or full ownership. There is a order of precedence where the occurrence of the taxable event by one right excludes the others. In the case of coexistence of usufruct and ownership, both rights generate the taxable event, resulting in two taxpayers obligated to pay based on their respective rights.
The DGT's position has undergone a reversal regarding the coexistence of usufruct and ownership. While in 2018 it was maintained that usufruct excluded the owner, ruling V0099-25 establishes that both rights generate the taxable event independently. The rest of the doctrine regarding surface rights and concessions remains constant.
Turning points
-
Established that usufruct excluded the owner from the taxable event, indicating that bare ownership did not constitute an element of the tax.
-
Reverses the previous doctrine by determining that when usufruct and ownership coexist, the taxable event is realized by both rights and there are two taxpayers.
