How the DGT's position has evolved
Current position
Vehicle adaptation services for the regular transport of persons with disabilities are taxed at the 4% rate. Repairs to these specific vehicles are taxed at the general rate of 21%. Homologation services and material transport are considered ancillary and follow the 4% adaptation rate. For the acquisition of the vehicle, prior recognition of the right by the AEAT (Spanish Tax Agency) is required.
The DGT's position remains constant in the distinction between adaptation (4%) and repair (21%) for regular transport vehicles. It has been specified that homologation services are ancillary to the adaptation. The requirement for prior recognition by the AEAT for the acquisition of the vehicle remains a requirement.
