Complete GST Billing Guide for Pharmacy & Medical Stores in India (2026)

Running a medical store in India is highly regulated. Beyond basic retail challenges, pharmacies must navigate complex GST rates, Drug License rules, and mandatory batch/expiry tracking. This guide covers the essentials for compliance in 2026.

1. GST Rates on Medicines

Medicines in India do not have a flat GST rate. - 0% (Exempt): Human blood and its components.
- 5%: Life-saving drugs, oral rehydration salts, insulin, vaccines.
- 12%: Standard pharmaceuticals, diagnostic kits, Ayurvedic medicines.
- 18%: Hair oils, cosmetics, certain dietary supplements.
Using an automated GST Calculator or proper billing software is essential to avoid mistakes.

2. HSN Codes for Pharma (Chapter 30)

Pharmaceutical products fall under Chapter 30 of the HSN code system. Depending on your aggregate turnover, you must mention 4 or 6 digits of the HSN code on your tax invoice. Always double-check codes via our HSN Code Lookup tool.

3. Batch & Expiry Tracking (Crucial)

Under the Drugs and Cosmetics Act, you cannot sell expired medicines. More importantly, if a manufacturer recalls a specific batch, you must instantly identify which customers bought it (if B2B) or remove it from shelves. A specialized pharmacy POS or custom desktop app enforces FIFO (First-In-First-Out) and alerts you before stock expires. Generic POS software often lacks robust batch management.

4. Schedule H and H1 Drugs

Certain prescription drugs (Schedule H1) require you to maintain a separate register detailing the patient's name, doctor's name, and quantity dispensed. Modern pharmacy software can automate this register generation during the billing process itself.

5. GSTR Filing for Medical Stores

Pharmacies deal with high volumes of B2C (Business to Consumer) invoices. Summarizing this data accurately for GSTR-1 (B2C large and small) is tedious manually. Ensure your software supports 1-click JSON export for the GST portal.
