The Central Board of Indirect Taxes and Customs (CBIC) has issued a warning regarding fake GST notices and summons being circulated by fraudsters. These fraudulent documents often mimic official communications, using the CGST logo and fabricated Document Identification Numbers (DIN). The CBIC urges taxpayers to verify the DIN of any communication on the official CBIC portal and report any discrepancies immediately to prevent scams and protect themselves from fraudulent activities.
