Managing GST compliance is a critical task for every Indian business. With frequent updates and strict deadlines, missing a filing can lead to penalties and interest. In this guide, we outline the key GST deadlines for the financial year 2026.
Monthly Filings
GSTR-1 (Details of Outward Supplies)
- Deadline: 11th of the following month for taxpayers with turnover > ₹5 Crores.
- Why it matters: This return is crucial for your customers to claim Input Tax Credit (ITC).
GSTR-3B (Summary Return)
- Deadline: 20th of the following month.
- Why it matters: This is where you calculate your final tax liability and pay the due amount.
Quarterly Filings (QRMP Scheme)
Small taxpayers with turnover up to ₹5 Crores can opt for the QRMP (Quarterly Return Monthly Payment) scheme.
- GSTR-1 (IFF): 13th of the first two months.
- GSTR-3B: 22nd or 24th of the month following the quarter (depending on the state).
Annual Return (GSTR-9)
- Deadline: 31st December following the end of the financial year.
Best Practices for Compliance
1. Regular Reconciliation: Reconcile your purchase register with GSTR-2B every month.
2. Timely Payments: Ensure tax payments are made before the 20th to avoid interest.
3. Accuracy: Double-check HSN codes and GSTINs before filing.
