On the 27th, it was learned from the State Administration of Taxation that on that day, tax departments in Tianjin, Heilongjiang, Guizhou, Chongqing and other places exposed four illegal cases of defrauding export tax refunds, with the highest amount involved exceeding 200 million yuan. From the exposed content, it can be seen that the criminal methods involved in these cases are concealed, the relationship chain is complex, and the amount of export tax refunds obtained in a short period of time is relatively large, which is noteworthy. For example, between 2020 and 2022, three companies, including Tianjin Runxingtai Supply Chain Management Service Co., Ltd., with Yang Rongdong as the actual controller, fraudulently obtained export tax refunds through illegal means such as signing false purchase and sale contracts, purchasing information from others' export declaration forms, and accepting upstream enterprises' false issuance of value-added tax special invoices. In the end, the tax department pursued the three companies involved in the case for fraudulently obtaining export tax refunds of 201 million yuan, and stopped processing export tax refunds for them within three years. Currently, Yang Rongdong and six others have been prosecuted on suspicion of defrauding export tax refunds. In addition, the main perpetrators of two cases, namely the case of seven enterprises with Liu Jingwei as the actual controller defrauding export tax refunds and the case of Chishui Huidafeng Trading Co., Ltd. defrauding export tax refunds, were sentenced for the crime of defrauding export tax refunds; The relevant personnel involved in the case of Hongyi Bioengineering (Chongqing) Co., Ltd. defrauding export tax refunds have been prosecuted. Export tax fraud involves multiple links such as production, trade, customs declaration, logistics, and foreign exchange collection, often with characteristics of cross regional, cross-border, and internal/external. It is highly covert and difficult to investigate. Therefore, eight departments including taxation, public security, courts, procuratorial, customs, the People's Bank of China, market supervision, and foreign exchange management continue to deepen cooperation, improve the normalized mechanism for cracking down on illegal tax fraud, and build a full chain and integrated crackdown system from administrative law enforcement to criminal justice. According to data from the State Administration of Taxation, in 2025, tax departments will further leverage the regular joint efforts of eight departments to crack down on tax related illegal and criminal activities. A total of 76000 suspected tax fraud enterprises will be inspected, and export tax refund losses exceeding 10 billion yuan will be recovered. Associate Professor Li Dongyan from the School of Economics at Nankai University stated that with the application of technologies such as tax big data and cross-border regulatory information sharing, the efficiency of joint efforts to combat tax related crimes continues to improve. Tax departments can quickly identify risk clues such as false invoices, false customs declarations, and abnormal fund flows, achieving precise crackdowns on professional, networked, and cross regional tax fraud gangs. The coordinated crackdown by multiple departments demonstrates the firm determination of the country to safeguard the healthy development of foreign trade. (New Society)
