The Ministry of Finance and the State Administration of Taxation issued the "Announcement on Clarifying the Calculation Basis of Taxable Sales Volume of Value-added Taxable Transactions".

Taxpayers transfer financial products, and calculate the sales amount by deducting the purchase price from the selling price. The positive or negative difference in the transfer of financial products is calculated based on the balance after offsetting gains and losses. If a negative difference occurs after offsetting, it can be carried over to the next tax period and offset against the sales amount of transferred financial products in the next period. However, if a negative difference still occurs at the end of the year, it cannot be carried over to the next accounting year. The purchase price of financial products can be calculated using either the weighted average method or the moving weighted average method, and once selected, it cannot be changed within 36 months. Taxpayers transferring financial products are not allowed to issue special value-added tax invoices. General taxpayers providing passenger station services calculate the sales amount by deducting the total taxable price obtained from the paid freight to the carrier. General taxpayers issuing invoices to buyers for all taxable prices obtained from providing passenger station services; the input tax corresponding to the freight paid to the carrier cannot be deducted from the output tax.
