Individual Investors Get Clarity From China’s Taxman on Overseas Income
Listen to the full version

As Chinese tax authorities ramp up oversight of offshore investment income, some holders of overseas trading accounts have been left wondering exactly how that income should be calculated.
Some retail investors with recent run-ins with the authorities now have an answer.
Chinese tax residents, including long-term foreign residents, have to pay a 20% rate on the net profit earned from stock trades made during the calendar year, according to several investors who spoke to Caixin. Specifically, net profit means the sum of their realized gains minus the sum of their realized losses for the entire year.
