How the DGT's position has evolved

Stable position High confidence 26 rulings · 2014–2024

Current position

Buildings are defined by their nature and permanence, excluding elements that can be moved without damage to the material, such as modular houses. The classification of a building determines the application of reduced tax rates and the reverse charge mechanism. In the case of housing, taxation depends on whether the transfer is the first or the second following the fulfillment of usage periods.

The DGT maintains a clear distinction between urbanization works, infrastructure, and buildings to determine the applicable tax rate. Jurisprudence and criteria have delimited that mobile elements or accessories to agricultural exploitation do not constitute buildings. The position remains constant regarding the application of the reverse charge mechanism and the distinction of rates according to the nature of the work.
