Issues of directors' personal liability for limited liability companies tax debts are related to the need to maintain an appropriate relationship between enforcement of obligations under the law and respect for the rights of subjects of these obligations. On the one hand, in the case of limited liability companies, we are faced with the problem of guaranteeing effective protection to the company's creditors, including public law creditors, and, on the other hand, with the need to maintain acceptable standards for imposing liability for the company's obligations as a separate legal entity. The conflict of these values becomes apparent with particular intensity in the situation of actual influence on the functioning of the company by persons who are not appointed as directors or act as a director without due authority. Analysis of Polish, German and Austrian law allows the conclusion that the scope of liability of de facto directors is sometimes shaped differently and the sources of such liability are different. The purpose of this article is to indicate the need for a statutory regulation of the legal position of a de facto director.
