"Hello, make out an invoice." "Mr. Wang, there is something wrong with the POS machine today. Please pay cash." Taxpayer Wang went to a collection point in Dongtai City, Jiangsu Province to issue an ordinary VAT invoice. Wu, a staff member of the collection point, didn't make President Wang have too much doubt. He paid the tax in full in cash, took the invoice and left the tax payment certificate. Before the tax settlement of the day, Wu cancelled Wang's tax ticket in the system, and he owned more than 300 yuan of tax. Since then, the POS machine of this generation of sign points has "failed" frequently. "It doesn't matter if you don't bring your ID card. I'll help you find someone else's ID card and issue a ticket, but the POS machine breaks down. You can transfer money directly to cash or wechat." Wu's service is extremely "enthusiastic". The Municipal Taxation Bureau carried out special verification on the settlement vouchers of cash bills and found that Wu, a staff member at the collection point, had a high frequency of voiding invoices, and the paper invoice copy was not recovered and voided. The tax authorities promptly transferred the clues of relevant problems to the Dongtai Municipal Commission for Discipline Inspection and supervision. The investigation began immediately. In order to avoid startling the snake, the investigation team of the Municipal Commission for Discipline Inspection and supervision found the buyer one by one from the periphery for verification according to the invalid invoice data. After the investigation, the facts began to surface: Mr. Wu chose the right object and time, and with a considerate manner, from dozens of yuan, hundreds of yuan to thousands of yuan, bit by bit "nibbled" the state's taxes. A total of 284 invoices were involved, involving 112000 yuan of taxes. There is a suspicion of embezzling taxes by means of "double cancellation", "transfer and payment", "red flush" and so on. Smart is mistaken by smart. Wu's every operation, without exception, has left an indelible electronic trace in the tax system. The invoices that have been voided, transferred and offset in the financial account books have become the iron evidence of his embezzlement of taxes. On October 8, 2021, Wu was detained. On December 6, 2021, Wu was transferred to the procuratorial organ for examination and prosecution. On December 9, 2021, Wu was relieved of his labor relationship. "In view of the problems exposed in this case, we draw inferences from one instance and issue supervision suggestions in time to strengthen the education and management of township tax assistants and plug the loopholes of the entrusted tax collection system in time." The principal responsible comrades of Dongtai Municipal Commission for Discipline Inspection and Supervision said. (outlook new era)
