The subject of this study are anti-money laundering issues. Significant changes in the system of prevention against this phenomenon were brought by the Act of 1 March 2018 and its implementing provisions. The entry into force of this law was dictated primarily by the need to adapt the national provisions to EU regulations, in particular the IV and V AML directives. However, the purpose of analyzing the provisions of the Act of 1 March 2018 is not only to show changes and to assess the shape of the current legal solutions, but also to indicate the direction of desired amendments. Putting forward the appropriate de lege ferenda postulates is justified in particular by the need to fully implement the relevant EU directives into the national legal order.
