GST compliance for pharma retailers has stabilised, but small mistakes still cost retailers refunds and notices. Here's the practical monthly checklist we share with our retail partners.
**Every month:** 1. Reconcile purchase invoices with GSTR-2B before claiming ITC 2. File GSTR-1 by the 11th — even if no sales (NIL return) 3. File GSTR-3B by the 20th with self-assessed tax 4. Keep e-invoices for B2B sales above ₹5 cr turnover threshold
**Every quarter:** - Reconcile cumulative ITC vs. GSTR-2B - Cross-check sales register against bank deposits
**Every year:** - File GSTR-9 annual return (by 31 Dec) - File GSTR-9C audit reconciliation if turnover above threshold
HMS Enterprises always issues GST-compliant invoices with HSN codes for every SKU. If a retailer needs a reissued or revised invoice, our accounts team turns it around within 24 hours.
