Staying on top of GST filing dates helps you save money, maintain compliance, and keep your business running smoothly. We have broken down the full Indian GST schedule so you have every important date in one place.
Here is your complete GST filing calendar;
🔹 GSTR-1 (Sales): Monthly filers with turnover above ₹5 Cr report outward supply and sales invoices by the 11th of every month. QRMP filers can use the Invoice Furnishing Facility (IFF) by the 13th to help B2B buyers claim ITC on time. Quarterly GSTR-1 follows the same 13th rule at quarter-end.
🔹 GSTR-3B (Payment): Monthly filers with turnover above ₹5 Cr calculate tax owed minus ITC and pay by the 20th. QRMP filers follow quarterly GSTR-3B dates, with the 22nd for South / Category 1 states and the 24th for North / Category 2 states, filed at the end of each quarter (Apr-Jun, Jul-Sep, Oct-Dec, Jan-Mar).
🔹 PMT-06 & IFF for QRMP Filers: PMT-06 Challan is due by the 25th of every month for monthly self-assessment tax payment when ITC is insufficient. IFF is optional and due by the 13th of every month, allowing B2B buyers to claim ITC without waiting for quarter-end.
🔹 QRMP Scheme Summary: Quarterly Return, Monthly Payment scheme at a glance. GSTR-1 and GSTR-3B are filed once per quarter, tax payment via PMT-06 is due monthly by the 25th, B2B invoice upload through IFF is optional by the 13th monthly, and the opt-in deadline is 31st January each quarter.
🔹 Composition Scheme: Designed for micro businesses (turnover under ₹1.5 Cr for goods or ₹50L for services). CMP-08 quarterly tax payment is due by the 18th of the month after quarter-end (Jul 18, Oct 18, Jan 18, Apr 18). GSTR-9 annual return is due by 30th April after the financial year ends. For FY 2025-26, the deadline is 30 April 2026.
🔹 GSTR-9 Annual Return: Due by 31st December every year. For FY 2025-26, the deadline is 31 Dec 2026. This covers a comprehensive summary of all monthly returns, ITC, and tax paid. It includes GSTR-9 for all regular taxpayers, GSTR-9C reconciliation for turnover above ₹5 Cr, and GSTR-9B for e-commerce operators (TCS).
🔹 The Cost of Delay: Filing on time keeps your money in your business. Late fees are ₹50/day for GSTR-1 and GSTR-3B with tax liability (₹25 CGST + ₹25 SGST), ₹20/day for Nil returns, subject to applicable statutory maximum limits. Interest on unpaid tax is 18% per annum, and repeated defaults may block e-way bill generation.
