A practical guide to GSTR-1, GSTR-3B, and annual returns. Never miss a deadline again.
Missing GST return deadlines means late fees, interest, and blocked ITC. Here's a clear calendar to stay on track.
Monthly Returns
GSTR-1 (outward supplies): 11th of next month. GSTR-3B (summary): 20th for turnover under ₹5 Cr, 22nd for ₹5–50 Cr, 24th for above ₹50 Cr. GSTR-2B is auto-generated by 14th—use it for reconciliation.
Annual Return
GSTR-9 (annual return): 31st December. GSTR-9C (reconciliation statement) if turnover > ₹5 Cr. Start compiling data from October—don't leave it for December.
Penalties
- •Late fee: ₹50/day (₹20 for nil return), max ₹10,000 per return
- •Interest: 18% p.a. on tax paid late
- •ITC: Claimed in GSTR-3B after due date may be disallowed
How to Stay on Track
- •Set calendar reminders 2 days before each deadline
- •Reconcile books by 5th of each month
- •Use auto-populated data from GSTR-2B
- •Consider return filing software with deadline alerts
Extension Notifications
CBIC sometimes extends deadlines for specific returns. Follow official GST portal and CBIC notifications. Don't assume—verify before relaxing.
One missed return can cascade: GSTR-1 delay affects your buyers' ITC; GSTR-3B delay blocks your own ITC. Consistency matters.
