GST compliance in India requires businesses to file multiple returns every month and quarter — and missing a due date carries immediate financial consequences. Late filing of GSTR-3B attracts interest at 18% per annum on the outstanding tax liability, plus a late fee of ₹50 per day (₹20 per day for nil returns), subject to a maximum cap. For GSTR-1, a late fee of ₹50 per day (₹20 for nil returns) applies, capped at ₹10,000 per return. Persistent non-compliance can result in cancellation of GST registration and block of e-Way Bill generation.

The three primary returns are: GSTR-1 (details of outward supplies, due on the 11th of the following month for monthly filers), GSTR-3B (monthly summary return with tax payment, due on the 20th), and GSTR-9 (annual return, due by 31 December after the financial year ends). Composition scheme taxpayers file GSTR-4 annually. For businesses with annual turnover up to ₹5 crore, the QRMP (Quarterly Return Monthly Payment) scheme allows quarterly GSTR-1 and GSTR-3B filing, with monthly tax payments through a fixed-sum challan in the first two months of each quarter.

Under the QRMP scheme, taxpayers can also use the Invoice Furnishing Facility (IFF) to upload B2B invoices for the first two months of each quarter — this allows their recipients to claim input tax credit without waiting for the full quarterly GSTR-1. The IFF due date is the 13th of the month following each non-quarter-end month. Reconciling GSTR-1 and GSTR-3B data, and ensuring GSTR-2A/2B matches claimed input tax credits, is an ongoing compliance obligation that penalties can compound quickly if neglected.

This GST due dates calendar covers all major GST returns for FY 2026-27: GSTR-1 and GSTR-3B for both monthly and QRMP filers, IFF, GSTR-4 (composition), GSTR-9, and GSTR-9C. Due dates are flagged as overdue (in red), upcoming within 7 days (in amber), or future. You can filter by filer type — Monthly, QRMP, or Composition — to see only the dates relevant to your business. Built and maintained by our Ex-Big 4 CA team.
