No need. Foreign exchange income is not subject to personal income tax. This also depends on the situation. If traders are speculating in real foreign exchange, they earn interest through currency exchange and foreign exchange savings. If they are converted into RMB and deposited in an account, they need to pay personal income tax. Of course, if you don't need to convert it into a RMB account, traders don't have to pay taxes. On the other hand, if the trader earns income through foreign exchange margin trading, then there is no need to pay taxes. Because of the foreign exchange margin trading, the trader's funds are deposited in foreign bank accounts, and the trading behavior also takes place abroad, which belongs to overseas income and does not need to be taxed.
