How the DGT's position has evolved
Current position
The reverse charge mechanism applies when the recipient is an entrepreneur or professional and the operation is a works execution (with or without materials) within the framework of the urbanization, construction, or rehabilitation of buildings. This mechanism extends to subcontractors if their contract derives from a main construction or rehabilitation contract. The supply of goods without installation is not considered a works execution.
The DGT's position remains constant regarding the application of the reverse charge mechanism. Throughout the rulings, it has been specified that works execution includes both supply with installation and works carried out by subcontractors within the framework of a main contract. No changes in criterion are observed, but rather an accumulation of clarifications regarding the scope of works execution.

Clarifies that the reverse charge mechanism also applies to works carried out by subcontractors within the framework of a main urbanization, construction, or rehabilitation contract.
