The catalog of instruments of reglamentation of economic activity included in chapter 4 of the Law of Entrepreneurs (concession, permit, entry in the register of regulated economic activity) does not exhaust the general structure of the reglamentation of undertaking economic activity in the Polish legal system. Numerous laws regarding specific fields of economic activity regulate legal instruments determining the admissibility of undertaking economic activity, which are located outside the catalog resulting from the provisions of the Law of Entrepreneurs. Although they have a similar effect to instruments arising from the Law of Entrepreneurs, their legal substance is different. These instruments should be included in the category of improper reglamentation of undertaking eco-nomic activity, in contrast to the proper reglamentation, which falls within the structure included in chapter 4 of the Law of Entrepreneurs. The instruments of improper reglamentation of undertaking economic activity are dispersed in three different branches of law — economic law, administrative law, and tax law.
