Previously, through situational awareness, the Economic Security Department of the Ninh Binh Provincial Police detected that Hao Thien Dai Duong Technical Equipment and Services Co., Ltd., directed by Ms. Trinh Thi Nghia (born in 1976, from Yen Khanh district, Ninh Binh province), showed signs of fabricating accounting documents and using illegal value-added invoices to declare and evade taxes.
During the investigation and verification process, the Economic Security Department gathered evidence confirming that Ms. Nghia, as the company director, colluded with Dinh Thi Tam (born in 1985) and Bui Thi Huong (born in 1993, both residing in Hoa Lu ward, Ninh Binh province), the company accountants, to falsify hundreds of accounting documents related to labor costs and purchase invoices. These fraudulent declarations totaled 15 billion VND, with 3 billion VND evaded from state tax revenues.
The defendants Nghia, Tam, and Huong have paid 1.8 billion VND in compensation for the damages caused.
The Economic Security Department has transferred the entire case file and related documents to the Security Investigation Agency of the Ninh Binh Provincial Police for further investigation and legal proceedings.
