4. MAIN PERFORMANCES 2018
The fundamental mission of the Tax Agency must be to promote voluntary compliance with tax obligations. It performs two lines of action to achieve this: On the one hand, fraud prevention through the provision of information and assistance services to taxpayers to facilitate and minimise indirect costs associated with compliance with tax obligations, together with the development of other preventive actions; and, on the other hand, the detection, regularization and, where appropriate, sanctioning of tax non-compliance through control actions. Both lines of action define the basic areas of its strategy, around which the main actions developed in 2018 have pivoted.
