Trading etf funds does not need to pay taxes, only need to pay commission fees. The maximum commission rate shall not exceed three thousandths, and if each transaction is less than five yuan, it shall be charged according to the standard of five yuan. Different securities companies have different commission rates.

For example, when the etf fund price is 2 yuan, investors sell 20,000 shares and the commission rate is three ten thousandths, then the commission fee to be paid when selling is 2× 20,000× 3/10000 =12 yuan.
