How the DGT's position has evolved

Stable position High confidence 13 rulings · 2014–2025

Current position

Classification in the IAE (Economic Activities Tax) depends on the material nature of the activity and not on the holder's designation. The installation of products may be included in the sales heading if the attached note allows it, as in the case of glass or kitchen furniture. In other cases, such as the installation of sanitaryware or bathroom furniture, registration in specific service headings such as plumbing or carpentry is required.

The DGT's position remains constant in requiring that the activity be classified according to its material nature. The rulings show a systematic application of the IAE Tariff notes to determine whether the installation is integrated into the sale or requires an independent service heading. No doctrinal change is observed, but rather a technical application of the classification rules.

Turning points

  1. V3097-21

    Confirms that the payment of the sales fee for glass authorizes installation without the need to pay tax under another heading, thanks to the note attached to heading 653.4.

  2. V2542-23

    Establishes that classification is carried out according to the material nature and that if assembly and maintenance are performed, tax must be paid under both the installation and repair groups.
