Pharmacy GST Billing: The Complete Guide for Medical Stores

Everything Indian chemist shops need to know about GST compliance: medicine tax slabs, pre-mapped HSN codes, ITC reconciliation, and filing error-free returns.

Key Takeaways for Pharmacy Owners

  • Most formulations fall under HSN 3004 at 12% GST (6% CGST + 6% SGST).
  • Life-saving drugs and oral rehydration salts are taxed at 0% or 5%.
  • Cosmetics, toothpastes, and energy drinks fall under 18% GST.
  • Proper input tax credit (ITC) reconciliation with GSTR-2B saves thousands in excess tax payments.

Unlike single-rate businesses, a chemist shop sells goods across 4 distinct GST brackets:

  • 0% (Nil Rated): Human blood, contraceptive pills, select life-saving drugs.
  • 5% GST: Vaccines, insulin, diabetic test kits, assistive devices (HSN 3002, 9021).
