How the DGT's position has evolved
Current position
The repair of vehicles and their electrical components, such as radios, screens, or key control unit programming, is classified under heading 691.2 of the IAE (Economic Activities Tax). This heading allows for the repair of any vehicle element and the replacement of parts. However, registration under this heading does not authorize the sale of parts without installation or the manufacture of accessory installations.
The DGT's position remains constant regarding the classification of vehicle repair under heading 691.2. Throughout various rulings, the scope of this heading has been clarified, extending it to the repair of electrical components and module programming, while maintaining the distinction from manufacturing or the sale of parts without assembly.
Turning points
-
It is established that subcontracting the material execution does not alter the classification under heading 691.2, provided that the taxpayer manages and takes responsibility for the result.
-
A distinction is made between the repair of automotive electrical components (heading 691.2) and the repair of household appliances (heading 691.1).
