The Indian government has announced significant GST updates, effective October 1, 2025, stemming from the Finance Act, 2025. These amendments will impact definitions, voucher taxation, Input Tax Credit (ITC) on plant & machinery (retrospectively from 2017), return filing procedures, appeal processes, and introduce a new 'track & trace' system with associated penalties. Businesses must prepare for these changes by reviewing operations, updating systems, and training staff to ensure compliance and manage potential cash flow implications.
