King Felipe VI of Spain enacted Law 34/2015 to significantly amend the General Tax Law 58/2003, aiming to enhance legal certainty, prevent tax fraud, and improve administrative efficiency. The reform introduces binding interpretative rules, imposes sanctions for abusive legal arrangements, and clarifies the distinction between the right to assess taxes and the right to investigate. Additionally, it updates inspection procedures, regulates indirect estimation methods, and establishes transparency measures including the publication of lists of major tax debtors.
