GST 2.0 is not an abstract tax-policy story for a clinic that stocks and bills medicines in-house. It is a line-item change on every pharmacy bill the clinic generates. A tablet that carried 12% GST in August 2025 may now carry 5%, or nil. A diagnostic kit or a glucometer sold at the front desk moved slabs on the same date. If the clinic's billing software still applies the old rate, every affected invoice is wrong from the moment it is printed, whether that means overcharging a patient or under-reporting output tax.
This article lays out exactly what changed under GST 2.0 for medicines and diagnostics, what a clinic's invoicing software actually needs to get right because of it, and where CuraVerto's billing engine helps and where the clinic still has work to do.
What changed under GST 2.0
The 56th meeting of the GST Council, held on 3 September 2025 and chaired by Union Finance Minister Nirmala Sitharaman, approved a rate rationalisation exercise widely referred to as GST 2.0. The CBIC gave effect to the changes through Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, with the revised rates applying from 22 September 2025. The notification collapsed the previous multi-slab structure into a simpler set of schedules, and moved most finished medicines and diagnostic items into the lowest taxable slab.
| Category | Rate before 22 Sep 2025 | Rate from 22 Sep 2025 |
|---|
| Most finished medicine formulations (tablets, syrups, capsules, etc.) | 12% | 5% |
| Specified life-saving drugs (named list, reported at 33 medicines) | 12% | Nil (0%) |
| Diagnostic kits and reagents | 12% | 5% |
| Blood glucose monitoring systems (glucometers) | 12% | 5% |
| Bandages, gauze, wadding, test strips | 12% | 5% |
| A small number of other pharmaceutical HSN codes | Varies | 18% (unchanged for select items) |
The last row matters as much as the others: GST 2.0 did not move every pharmaceutical HSN code down. A handful of items stayed where they were. That means a clinic cannot safely bulk-apply "12% became 5%" across its entire catalog — the correct treatment is still per HSN code, checked against the notification, not assumed.

What a clinic's invoicing software needs to handle correctly
Correct rate at HSN-code level, not category level
Because GST 2.0 did not move every pharmaceutical HSN code to the same new rate, billing software needs to store and apply GST per HSN code, not as one blanket "medicines" rate. A system that lets staff set a single default GST percentage for the whole pharmacy catalog will get the exception items wrong.
Input tax credit knock-on effects on transition stock
Stock purchased before 22 September 2025 was taxed at the old rate; the same stock is now sold at the new, lower rate, or in some cases at nil. When an item moves to nil-rated, input tax credit already claimed or available on that stock does not carry forward the same way it does for a taxable supply, and may need to be reversed. Figuring out the exact number is an accounting question, not a software question, but the software has to make the underlying data visible: which HSN code, what rate before, what rate after, and on what date the item transitioned. Without that, the reconciliation cannot happen at all.
A visible, auditable rate history per item
A GST auditor reviewing invoices spanning September 2025 will see the same drug billed at 12% before the 22nd and at 5% or nil after it. That is expected and correct, but only if the system can show why the rate changed, when, and on whose instruction. A silent bulk edit to a catalog rate with no record of the change is a harder position to defend at audit than a small, dated log of what moved and why.
None of this is exotic. It is the same discipline GST already demands: the right rate, on the right HSN code, applied consistently, with a record of what changed and when. GST 2.0 just moved the numbers.
Where CuraVerto helps, and where the clinic still owns the work
CuraVerto's billing engine does not hardcode a GST percentage anywhere in its calculation path. Every pharmacy catalog item and every invoice line carries its own configurable GST rate, and CuraVerto computes CGST and SGST from whatever rate is set on that line at the point of billing. That means CuraVerto can apply 5%, nil, or 18% correctly per HSN code the moment a clinic's catalog reflects the current slab — there is no code change required to bill at the new GST 2.0 rates.
What CuraVerto does not do is retroactively rewrite an existing pharmacy catalog for a clinic. Updating each drug and diagnostic item's GST rate to match the GST 2.0 slabs is a data step the clinic, or its onboarding and migration team, still has to carry out, HSN code by HSN code, against the notification. CuraVerto's billing engine is built to apply whatever GST slab is configured, accurately and consistently, once that configuration reflects the current law — it does not substitute for checking the law itself.
Frequently asked questions
What is GST 2.0 and when did it take effect?
GST 2.0 refers to the rate rationalisation approved at the 56th GST Council meeting on 3 September 2025 and notified by the CBIC via Notification No. 9/2025-Central Tax (Rate) dated 17 September 2025. The revised rates took effect from 22 September 2025, collapsing the previous four-slab structure (0/5/12/18/28%) into a simpler structure and moving most items, including most medicines, into lower slabs.
What GST rate do medicines attract now?
Under GST 2.0, most finished medicine formulations that were taxed at 12% moved to 5% with effect from 22 September 2025. A specified list of life-saving drugs moved from 12% to nil (0%). Not every pharmaceutical HSN code changed; a small number of items remain at 18%, so the correct rate still has to be checked and set per HSN code rather than assumed from the old default.
Are any medicines at 0% GST after GST 2.0?
Yes. The CBIC notification names a specific list of life-saving drugs, reported at 33 individually named medicines, that moved from 12% to nil. This is a named list, not a general category, so a clinic pharmacy needs to check whether a given drug is on that list rather than assume nil-rating applies broadly.
What GST rate applies to diagnostic kits, reagents, and glucometers now?
Diagnostic kits, reagents, blood glucose monitoring systems (glucometers), bandages, gauze, and test strips moved from 12% to 5% under the same 22 September 2025 change. These items sit in the same reduced slab as most finished medicines.
What does GST 2.0 mean for input tax credit on existing pharmacy stock?
When a medicine's output GST rate drops, and especially when it drops to nil, the input tax credit already claimed or available on stock purchased at the old, higher rate can be affected: nil-rated supplies do not carry input tax credit forward the way a 5% taxable supply does. Working out the exact reversal, if any, on transition stock is a question for a chartered accountant, but it is only answerable if the clinic's system can show, item by item, which HSN code changed rate and on what date.
Does CuraVerto apply the new GST 2.0 rates automatically?
CuraVerto's billing engine does not hardcode a single GST percentage anywhere in the calculation path. CuraVerto lets every catalog item and invoice line carry its own gst_pct and computes CGST/SGST from whatever rate is set on that line, applying 5%, 0%, or 18% per HSN code without any code change. CuraVerto does not, however, retroactively rewrite an existing pharmacy catalog to the new slabs on its own — updating each drug's rate to match GST 2.0 is a data step the clinic (or its onboarding/migration partner) still has to do, HSN code by HSN code.
