GST for Pharmacy in India: Rates, Registration & Filing
Current GST rates on medicines after the 2025 rate cut, registration thresholds, input tax credit, and how to handle expired stock in your returns.
This covers GST for pharmacy owners by product category, registration thresholds, how input tax credit actually works, and the specific handling GST requires for expired and returned stock.
What are the current GST rates on medicines?
Three rates apply to pharmacy stock as of the 2025 rate change: Nil for a specified list of critical drugs, 5% for the general category most prescription and OTC medicines now fall under, and 18% for dietary supplements, vitamins and similar wellness products that aren't classified as medicines.
| Rate | Applies to |
|---|---|
| Nil (0%) | 36 specified critical and life-saving drugs, human blood, contraceptives |
| 5% | Most prescription medicaments (HSN 3004), vaccines, insulin, oral rehydration salts, basic diagnostic kits |
| 18% | OTC dietary supplements, vitamins, protein powders, and specific medical devices or lab reagents |
The move from 12% to 5% for the general category is the headline change from September 2025, per the GST Council's own rate rationalisation and confirmed independently by EY's tax alert on the same reform. The 36-item Nil list is specific and named rather than a broad category, so a drug needs to actually appear on that list to qualify for zero rate rather than merely being "essential" in a general sense.
Why does the HSN code on an invoice actually matter?
Every invoice a pharmacy issues needs the correct HSN code, generally under Chapter 30 for pharmaceutical products, with 3004 covering most finished medicaments specifically. Getting the HSN code wrong isn't just a paperwork detail; it directly determines which rate the transaction is taxed at.
A wrong code can mean charging the wrong GST rate on an invoice without the error being obvious until a reconciliation or audit catches it, often months later.
Point-of-sale and billing software that pulls the HSN code automatically from a product master list, rather than requiring manual entry per transaction, removes most of the risk of this mismatch happening at all. Our documents checklist covers GST registration alongside the other paperwork a new pharmacy needs before it can legally invoice a single patient.
Does a pharmacy need to register for GST, and at what threshold?
GST registration becomes mandatory once annual turnover crosses the threshold set for goods suppliers, which is lower for special category states than for the rest of India, so check the specific threshold your state falls under rather than assuming a single national number applies uniformly.
This is exactly the kind of detail that varies by state and changes the compliance timeline for a new pharmacy planning its first year of operation. Below the threshold, registration is optional, though many pharmacies register anyway to claim input tax credit on their own purchases, which only registered businesses can do.
Registering below the mandatory threshold is a genuine strategic choice worth considering, not merely early compliance for its own sake. The ability to offset GST paid on wholesale purchases against GST collected from patients can materially affect a pharmacy's actual margin, which we break down alongside other cost factors in our pharmacy profit margin guide.
How does input tax credit actually work for a pharmacy?
A pharmacy registered under GST can claim input tax credit on GST already paid to its wholesale distributor. That reduces the net GST it owes to the government down to the difference between what it collected from patients and what it already paid upstream, on the same stock.
This is the mechanism that prevents GST from compounding at every step of the supply chain, and it's a real, calculable saving rather than a technicality worth ignoring. On a pharmacy doing meaningful monthly turnover, ITC correctly claimed is genuine money, not an accounting abstraction.
Claiming ITC correctly depends on the wholesale purchase invoice itself being GST-compliant and correctly matched in your returns, which is exactly why reconciling purchase invoices against what your supplier has actually filed matters operationally, not just for record-keeping purposes nobody looks at again.
How should a pharmacy handle GST on expired or returned stock?
Expired or returned medicines handled through credit notes need precise matching in your regular GST returns, reversing the input tax credit originally claimed on stock that's now being written off rather than sold.
Skipping this reversal, whether through oversight or simply not tracking it carefully, leaves a pharmacy claiming credit on medicine that was never actually sold to a GST-paying customer. That's exactly the kind of mismatch a GST audit is designed to catch.
This is one more reason batch-level inventory tracking matters beyond the operational case for it. Our inventory management guide covers the operational side of catching expiry before it becomes a write-off, and the GST reversal process depends on that same tracking discipline being in place.
What changed specifically in the September 2025 GST reform?
The reform reduced GST on all drugs and medicines broadly from 12% to 5%, and separately granted a Nil rate to 36 specified drugs, under a wider GST rate rationalisation exercise covering many product categories beyond pharmaceuticals.
The stated intent, per EY's analysis of the reform, was making long-term and chronic-illness treatment more affordable by cutting the tax embedded in medicine prices, which matters most for patients managing conditions requiring ongoing medication rather than a one-time prescription.
For a pharmacy, this means older pricing built around a 12% GST assumption needs updating, both in billing software configuration and in any cost estimates given to patients. Continuing to charge the old rate after the change is both a compliance problem and an overcharge a patient could reasonably contest, and it's worth auditing your own billing system specifically rather than assuming it updated automatically.
What GST returns does a pharmacy need to file, and how often?
A GST-registered pharmacy typically files monthly returns covering outward supplies and the tax collected on them, alongside a periodic reconciliation return matching purchases against what suppliers have themselves filed. Missing a filing deadline attracts a late fee that compounds daily until the return is actually filed, which on a small pharmacy's thin margins can add up faster than owners expect if a filing slips by even a few weeks.
Most pharmacies handle this through an accountant or GST-filing software rather than manually, precisely because the reconciliation step, matching your purchase records against your supplier's own GST filings, is tedious and error-prone to do by hand every single month. Automating it isn't a luxury once transaction volume is real; it's the only realistic way to avoid a mismatch surfacing months later as a discrepancy nobody can immediately explain.

FAQ
Frequently asked questions
Following the September 2025 rate change, most medicines carry 5% GST, 36 specified critical drugs carry Nil, and dietary supplements or OTC wellness products carry 18%. The pharmacy itself doesn't have a single GST rate; the rate depends on the specific product being sold.
Pharmacists as service providers aren't broadly GST-exempt, but the specific medicines they dispense may fall under Nil or reduced rates depending on classification. Registration and rate obligations apply to the pharmacy business, not to the pharmacist's professional status itself.
Most general prescription medicaments classified under HSN 3004, along with vaccines, insulin, and oral rehydration salts, currently carry 5% GST following the 2025 rate reduction from 12%.
For general medicines previously taxed at 12%, yes, that rate moved to 5% under the September 2025 rate rationalisation. Some other product categories in the wider GST structure may still use different slabs, so verify the specific classification of any product in question rather than assuming a blanket removal.
