Obligation to register for IAE for cylinder maintenance and gas refilling

The Directorate General of Taxes (DGT) has issued a relevant ruling regarding the correct registration in the Economic Activities Tax (IAE) for companies operating in the gas and cylinder management sector. The inquiry focuses on determining which headings should be applied when an entity performs maintenance activities and, simultaneously, manages gas refilling through third parties.

What the DGT has ruled

After analyzing the activity, the DGT has established that the entity is obliged to register under specific headings according to the nature of each service provided:

• Maintenance and inspection: The company must pay tax under heading 699 for the maintenance and inspection tasks of the cylinders.
• Gas refilling: Regarding the gas refilling service, the obligation to pay tax persists even if this process is carried out through the subcontracting of third-party services. In this case, the entity must pay tax under heading 652.2 or 655.2, depending on the technical characteristics of the products managed.

The ruling emphasizes that outsourcing the material execution of the activity does not displace the tax responsibility of the entity that offers the final service to the client.

What this means for you

If your company offers cylinder and gas management services, subcontracting the operational phases does not release you from the obligation to register under multiple IAE headings. The administration considers that the main economic activity remains the management of the service, which requires correct classification in the headings corresponding to both maintenance and the commercialization or management of the gases.

What you should do

It is necessary to verify that your entity's IAE registration status reflects all the activities it carries out, including those executed through third parties. An erroneous classification of headings could lead to contingencies before the Administration. It is recommended to assess the composition of your services to ensure that each activity is correctly linked to its corresponding heading according to the IAE Instruction RD Leg. 1175/1990 and the TRLRHL.
