The National Tax Administration’s Jiaozuo Tax Bureau Investigation Unit conducted a lawful investigation into a tax intermediary that assisted companies in deregistering illegally, resulting in underpayment of taxes. The intermediary, operating under the guise of facilitating business closures, provided fraudulent documentation to help clients avoid tax liabilities. Following a rigorous inquiry, the unit initiated administrative penalties against the intermediary and imposed fines commensurate with the magnitude of the tax evasion. This action sends a clear message that any facilitation of illegal deregistration will be met with swift legal consequences. The case also illustrates the authorities’ commitment to closing loopholes that tax evaders might exploit through third‑party services. Stakeholders are reminded that legitimate business closure procedures must comply with all tax obligations, and any deviation will be scrutinized. The successful prosecution reinforces the integrity of the tax system and serves as a deterrent to other intermediaries who might consider similar illicit activities.
