<h1>Fake Input Tax Credit detection prompts arrests and disruption of nationwide syndicates using shell firms and KYC misuse.</h1> The Directorate General of GST Intelligence uncovered widespread fake Input Tax Credit (ITC) fraud by networks that created and operated shell firms, misused KYC documents, and used one person companies to pass ineligible ITC. Investigations relied on e way bill analytics and IP address tracing to detect linked firms, leading to searches, seizures of electronic and documentary evidence, recorded admissions, and arrests of operators who facilitated fake firms and digital signature forgeries.
