GST compliance has become increasingly complex with over 1.4 crore registered taxpayers filing returns monthly and evolving regulations that demand precise adherence to deadlines and procedures. Non-compliance can result in penalties exceeding ₹10,000 per month, interest charges at 18% annually, and potential business disruption through assessment proceedings. Mastering GST compliance, return filing procedures, and penalty avoidance strategies is essential for businesses to maintain operational efficiency while maximizing input tax credit benefits and minimizing tax burden.
Compliance Alert: Late GST filing attracts ₹200 daily penalty plus 18% interest. A 6-month delay can cost ₹36,000+ in penalties alone, excluding interest and potential assessment proceedings.
