Current position

Living together through registration in the municipal register (empadronamiento) or a common tax domicile is considered one of the preferred means of proof to certify the destination of a vehicle with a reduced tax rate. However, living together is not an indispensable requirement to apply the 4% tax rate on vehicles intended for the transport of persons with disabilities. The final assessment of the evidence remains subject to current regulations.

The DGT's position on the means of proof is heterogeneous depending on the subject matter. Regarding invoicing, a constant doctrine is maintained concerning the validity of documents without the designation 'invoice', provided they meet the minimum legal content. In other areas, such as residence or the transport of persons with disabilities, a plurality of means of proof is admitted, prioritizing some over others.
