Foreign exchange tax is a foreign exchange management measure. Refers to the tax levied by the state on people and institutions that purchase foreign exchange. For example, some countries that implement foreign exchange control impose foreign exchange taxes in order to restrict imports, forcing the cost of imported goods to increase, thus playing a role in restricting imports. Generally speaking, it refers to one of the ways for the state to implement foreign exchange control. According to different types of import trade, different foreign exchange taxes are levied on the foreign exchange needed for import to limit the use of foreign exchange.
Due to the territorial tax policy in Hong Kong, under normal circumstances, remittances from the mainland to Hong Kong do not need to be taxed. I study finance, but I don't quite understand how you get this overseas tax, because no matter whether you go to Hong Kong with foreign exchange money from the mainland or China, there is no overseas tax, only the mainland collects it, so this is mostly for consumers to bear the handling fee required for business transfer. This is absolutely not in line with legal procedures.
