Overview
GST return filing is the regular reporting of your business's GST transactions to the government. Every registered taxpayer must file returns — typically GSTR-1 (details of outward supplies) and GSTR-3B (summary return with tax payment) — either monthly or quarterly depending on your turnover and scheme.
Late filing triggers automatic penalties of ₹50/day (₹20/day for nil returns), interest on unpaid tax at 18% per annum, and blocking of your Input Tax Credit. Consistent late filing can even lead to GST cancellation.
Big4India's GST filing service takes the entire burden off your shoulders. Our CAs reconcile your sales and purchase data, maximize your ITC claims, file accurate returns on time, and alert you to any discrepancies before they become problems.
