中国央行主管媒体《金融时报》：近期有纳税人收到了税务部门通知，告知其需要依法办理境外所得申报并缴纳相应税款。“根据我国个人所得税法，个人股票交易所得属于财产转让所得，应当适用20%的税率按次征收。其中，个人在境内二级市场的股票交易所得暂免征收个人所得税；在境外直接进行股票交易所得没有免税规定，需要在取得所得的次年申报纳税。”吉林财经大学税务学院院长张巍解释说。 ...

Core Viewpoint - Recent notifications from tax authorities indicate that taxpayers must declare and pay taxes on overseas income, including stock trading profits, as per Chinese tax law [1][2]. Taxation on Overseas Stock Trading - Taxpayers engaged in overseas stock trading are uncertain about tax obligations, especially regarding the calculation of gains and losses from transactions [1]. - According to Chinese tax law, income from stock trading is classified as property transfer income and is subject to a 20% tax rate. There is no tax exemption for overseas stock trading, and taxpayers must declare income in the following year [1][3]. - The tax authorities allow taxpayers to offset gains and losses within the same tax year but do not permit cross-year loss offsets [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 [3]. - China's tax system combines comprehensive and classified taxation, allowing for annual calculation of gains and losses, which is considered a reasonable approach [3]. Regulatory Measures - The tax authorities are enhancing oversight of overseas income taxation as part of efforts to regulate high-income earners and promote fairness [3][4]. - The implementation of the Common Reporting Standard (CRS) allows tax authorities to access data on residents' overseas financial accounts, facilitating the detection of underreported overseas income [3]. Compliance and Penalties - Taxpayers who fail to declare overseas income may face penalties, including back taxes and late fees. Serious cases could lead to investigations by tax authorities [6]. - Taxpayers are encouraged to correct any previous underreporting of overseas income promptly [6].
