In Turkish law, participation in tax crimes is punished within the framework of the general provisions regulated in the Turkish Criminal Code. Regarding complicity, a special provision has been made in the Tax Procedure Law (TPC) to be applied only to tax evasion crimes. Therefore, in Turkish law, the criminal liability of the participants in tax crimes will be determined primarily within the framework of the general provisions within the scope of the TPC, then the special regulation in Article 360 of the TPC will be applied only for tax evasion crimes. Although participation in Northern Cyprus law is divided into perpetrator and accessory in parallel with the English law, the partners are also punished with the prescribed penalty, without making any distinction between the participants in the crime. However, the situation is different for tax crimes. This difference stems from the fact that the Tax Procedure Law No. 27/1977 in Northern Cyprus Law was adapted from Turkish law. This composite structure is especially in question in the crime of tax fraud crime, as it is called in Northern Cyprus law. General provisions regarding complicity in Chapter 154 Criminal Code are valid for crimes other than fraudulent tax offenses in Northern Cyprus TPC. In this study, the appearance of the subsidiary institution in tax crimes in Turkey and the TRNC has been examined separately. By mentioning the structure of the institution of participation in tax crimes in the TRNC, the basis of the problems experienced in practice has been pointed out. Since the scope of the study is not to detail the institution of participation, discussions in the criminal law doctrine regarding the legal basis of participation rules are not included.
