The article analyses the legal status of separate church organizational units as described in article 12 of the Act from 17 May 1989, concerning the relationship between the State and the Catholic Church in the Republic of Poland, recognized by an adequate head of the tax chamber as separate tax entities. The author will prove that a rule specified in said regulation – namely that the aforementioned units are solely organizational separations within church, and legal persons may use their credentials in legal matters with third parties – is subject to exemption when it comes to labour and tax law. Moreover, the author will outline disadvantages of the existing regulations in this respect, especially when it comes to reporting and the rules of income tax on legal persons. Evaluation of de lege lata status will be completed by de lege ferenda postulates.
