加强个人境外收入监管，境外买卖股票收入也要缴税→

Core Viewpoint - Recent notifications from tax authorities require taxpayers to declare and pay taxes on overseas income, particularly from stock trading, which raises questions about tax obligations and calculation methods [1][2]. Taxation on Overseas Stock Trading - According to China's individual income tax law, income from stock trading is classified as capital gains and is subject to a 20% tax rate. Unlike domestic stock trading, which is currently exempt from personal income tax, overseas stock trading does not have such exemptions and must be declared in the following year after income is earned [1]. - Taxpayers are allowed to offset gains and losses from overseas stock trading within the same tax year, but cross-year loss offsets are not permitted under current regulations [2][3]. Tax System Comparison - Other countries, such as the US, Germany, and Australia, also tax overseas stock trading, but they often employ a progressive tax rate system that can exceed China's flat 20% rate. China's tax system combines both comprehensive and classified approaches, allowing for annual calculation of gains and losses [3]. Regulatory Measures and Compliance - The tax authorities are enhancing oversight of overseas income taxation as part of broader efforts to promote fairness and common prosperity. The implementation of the Common Reporting Standard (CRS) allows for automatic exchange of tax information, enabling authorities to identify underreported overseas income [3][4]. - Recent cases from tax departments in regions like Hubei and Shandong highlight the proactive measures taken against taxpayers who fail to declare overseas income, resulting in significant penalties and back taxes [4][6].
