The taxation of stock speculation at the University of Tokyo is basically 183 days to you, and you can conclude that you have not slept on practical experience. The taxation of the University of Tokyo follows the household registration + submission information, not the 183-day residence, it's that simple. Tell two cases, good cases are more efficient than reading what lies Deepseek generates. Case 1: My friend is a Singaporean EP, no longer living in China, and he has a Singapore tax payment certificate, why was he also called? Because the tax status information in the past data has not been updated. Or the bank/brokerage deceived you into updating it, but it didn't update. Or your mobile phone number, address, etc. The bank thinks you are still in China. Case 2: Why haven't I heard that the vast majority of Chinese holding H1B / green cards in the United States are taxed? This should not be the hardest hit area for US stocks Because most of them studied in the United States, all brokerage/bank registration information from graduation is US SSN, has nothing to do with Chinese tax status, and the United States does not participate in CRS. But if you go to Hong Kong/Singapore to open an account with Chinese information and use it frequently, it is hard to say.
