Chatgpt 给的关于预扣税的答复，大家自行判断： For developers from China, Apple currently applies a withholding tax rate of 30% to earnings from the App Store. This rate is deducted by Apple before paying out the net earnings to the developer.
However, China and the United States have a tax treaty in place that allows for a lower withholding tax rate of 10% on certain types of income, such as royalties, if certain conditions are met. To qualify for the reduced rate, the developer must provide Apple with a valid tax identification number, such as a U.S. taxpayer identification number (TIN) or a Chinese taxpayer identification number (TIN).
It's important to note that the withholding tax is not the final tax liability of the developer, but rather an estimated advance payment towards the final tax liability. The developer may be required to file a tax return and pay additional taxes or receive a refund, depending on their individual tax situation and the tax laws of their country. It's recommended that developers consult with a tax professional to understand their tax obligations in their specific situation.
