How the DGT's position has evolved
Current position
The reverse charge mechanism applies when the operation is an execution of works for urbanization, construction, or rehabilitation and the recipient is an entrepreneur or professional. The supply of goods with installation and assembly is considered an execution of works if the elements are incorporated into the building. The reverse charge does not apply to the mere supply of materials, in maintenance operations, or in installations carried out in buildings that are already completed.
The DGT's position has remained constant over time. The criterion focuses on distinguishing the execution of works from the mere provision of services or supplies, requiring that the installation involves the incorporation of goods into a building undergoing construction or rehabilitation.
