Current position

The burden of proof lies with the interested party to substantiate the facts that entitle them to benefits, exemptions, or reduced rates. In cases of residence, the filing of tax returns in Spain creates a presumption of residence that the taxpayer must rebut with evidence to the contrary. For other scenarios, such as the reuse of packaging or the transport of persons with disabilities, any means of proof admissible under the law is accepted.

The DGT's position is consistent in assigning the burden of proof to the taxpayer to substantiate facts that enable tax benefits. No change in doctrine is observed, but rather a systematic application of this principle across various matters, from Corporate Tax (IS) to Personal Income Tax (IRPF). The evolution shows a uniform application of the principle that whoever invokes a right must prove the facts that support it.
