This article presents the main problems connected with complaints to administrative courts against individual interpretations of tax law. The authors distinguished two categories of admissibility of a legal action in judicial administrative proceedings with respect to individual interpretations of tax law: subjective and objective admissibility of a legal action in judicial administrative proceedings. The first category concerns the form and type of an interpretation. On the other hand, the second category concerns the entities authorised to lodge a complaint against individual interpretation of tax law to an administrative court, the entities whose activities are the subject of a complaint, as well as court appropriate for the case which was initiated as a result of lodging a complaint against the interpretation. Moreover, the issue of formal requirements of a complaint and the scope of control exercised by an administrative court on individual interpretations of tax law were discussed.
