专家解读境外股票交易计税规则：允许按年度盈亏互抵

Core Viewpoint - The article discusses the taxation of overseas income for Chinese residents, specifically focusing on the taxation of capital gains from foreign stock trading, which is subject to a 20% personal income tax rate according to Chinese tax law [1][2]. Group 1: Taxation Regulations - Chinese residents are required to pay personal income tax on income obtained from both domestic and foreign sources, with a tax rate of 20% applicable to interest, dividends, rental income, capital gains, and occasional income [1]. - Personal stock trading income is classified as capital gains and is subject to the 20% tax rate, with exemptions for domestic secondary market transactions [1]. Group 2: International Practices - The taxation of capital gains from foreign stock trading is a common practice among major economies such as the United States, Germany, and Australia, as well as many developing countries [1]. - High trading frequency and price volatility in stock trading lead to significant tax burdens and complexities in tax calculations, as losses cannot be deducted from gains on a per-transaction basis [1]. Group 3: Current Taxation Approach - The tax authorities currently allow for the offsetting of gains and losses from overseas stock trading within the same year, which simplifies tax calculations for taxpayers [1][2]. - The existing tax law does not explicitly address the carryover of unutilized losses to future years, but the tax authorities have adopted a reasonable approach by allowing annual offsetting of gains and losses [2].
