First, it is in line with international standards. Judging from the international gold tax environment, the tax removal in the international circulation of gold is the mainstream, and most gold futures transactions have to pay value-added tax. Second, judging from China and Hong Kong, which have the greatest influence on our domestic market, Hong Kong is a free port with low tax revenue and low tax rate. At present, its taxes are mainly divided into three categories: profit tax, salary tax (personal income tax) and property tax. Hong Kong does not levy value-added tax, sales tax and capital gains tax, but only taxes the income obtained in Hong Kong. By comparing the gold tax policies of Hongkong and China, we can see that the pricing difference space formed by the tax differences between the two markets prompted China to implement the value-added tax on gold transactions immediately. Third, from the upstream and downstream of domestic gold trading, the implementation of value-added tax on gold trading can curb gray channels, promote normal trading and maintain a good market order.
