GST 2.0 India: 12% Slab Removed, New Rate Structure Explained (2025–26)
Published 11 July 2026 · GST & TDS
Vikram runs a packaging supplies business in Surat. He's been charging 12% GST on his HSN 4819 goods since 2017. In October 2025, his accountant called: that HSN had moved to 18%. Vikram's billing software still showed 12%. He had already raised 47 invoices that month.
On ₹8.4 lakh in October sales, he had collected ₹1,00,800 in GST from customers but owed the government ₹1,51,200. The ₹50,400 difference came out of his pocket.
GST 2.0: What the GST Council Did in September 2025
Since 2017, GST operated on four rate slabs: 5%, 12%, 18%, 28%. The GST Council's rate rationalisation committee had been recommending changes since 2023. In September 2025 — the biggest restructuring since the original rollout — the council eliminated the 12% slab as a standard category.
Items at 12% moved in one of two directions: down to 5% if they were considered essential goods, or up to 18% if they were discretionary. The 28% slab was narrowed further. At the top, goods already paying 28% + compensation cess had their combined rate formalised into a single 40% rate — this wasn't a new tax, just a cleaner label for what was already being charged on tobacco, aerated drinks, and certain luxury goods.
The effective result for most businesses: a three-tier GST structure — 5% (essential), 18% (standard), 28%/40% (luxury and sin goods). The 12% band is gone.
Where Did the 12% Items Go? Key Category Moves
These are directional changes for major categories. Your specific HSN code determines the exact rate — verify on the GST portal's HSN search tool or with your CA before updating billing software.
| Category | Old Rate | New Rate | Direction |
|---|---|---|---|
| Basic apparel (cotton, synthetic below ₹1,000) | 12% | 5% | Reduced |
| Food processing equipment | 12% | 5% | Reduced |
| Health and fitness equipment | 12% | 5% | Reduced |
| Construction materials (non-affordable housing) | 12% | 18% | Increased |
| Packaged beverages (non-carbonated) | 12% | 18% | Increased |
| Packaging materials (many HSNs — verify) | 12% | 18% | Increased |
| Standard IT and cloud services | 18% | 18% | No change |
| Luxury watches, bags above ₹25,000 | 28% + cess | 40% combined | Formalised |
| Restaurants (non-AC, no liquor) | 5% | 5% | No change |
April 2026: Two Compliance Rules That Hit Businesses Harder Than the Rate Change
1. Zero Mismatch ITC Policy
From April 2026, Input Tax Credit claimed in GSTR-3B cannot exceed what appears in your auto-generated GSTR-2B statement. If your supplier files GSTR-1 late — or doesn't file at all — that credit won't appear in your GSTR-2B. You can't claim it until they file.
In practice: every month, before filing GSTR-3B, you need to check GSTR-2B, identify which supplier invoices are missing, and follow up before the 20th. Your reconciliation process just became a monthly critical-path item, not an afterthought.
2. E-Invoicing Mandatory Above ₹5 Crore
The e-invoicing threshold dropped again — from ₹10 crore to ₹5 crore from April 2026. If your aggregate annual turnover crossed ₹5 crore in any preceding year, every B2B invoice must now be registered on the Invoice Registration Portal (IRP) and carry an IRN (Invoice Reference Number).
Buyers can't claim ITC on invoices without an IRN. This means if you are above ₹5 crore and not yet on e-invoicing, you are already costing your customers ITC — and they will find a compliant supplier faster than you think.

Calculate GST Under the New Rate Structure →What Most Businesses Get Wrong
Assuming you can correct the wrong rate in the next quarter. You cannot simply issue a credit note in October for invoices billed at 12% in September when the correct rate was 18%. The GST department's zero-mismatch enforcement means your GSTR-1 data is compared against the HSN rate notification in real time. If you billed 12% on a 18% item, you owe the 6% differential from your own money — and interest under Section 50 at 18% per annum from the due date.
Assuming composition scheme businesses are unaffected. Composition scheme taxpayers pay a flat rate on turnover (1%, 2%, or 5%) and don't track ITC. Rate changes don't directly affect their quarterly CMP-08 payment. But if you supply goods whose rates changed, your pricing relative to competitors on the regular scheme shifts. A competitor who was at 12% regular scheme and moved to 5% now has lower embedded GST cost. Worth recalculating whether the composition scheme still gives you a cost advantage.
What the Zero-Mismatch Policy Is Really About
The government cannot afford to audit every small supplier's GSTR-1 filing. There are over 1.4 crore GST registrants in India. The zero-mismatch ITC policy is designed to make large businesses do the enforcement instead.
If a large buyer can't claim ITC because their small supplier didn't file GSTR-1, the large buyer will stop buying from that supplier — or will refuse to pay until the supplier files. The government achieves nationwide GSTR-1 compliance without deploying a single additional tax officer. The compliance enforcement gets outsourced to the private sector's commercial relationships.
Smart policy? Yes. Good for small suppliers who get squeezed by large buyers threatening to withhold payment? That's a different question.
Frequently Asked Questions
How do I find the correct GST rate for my specific product after GST 2.0?
Go to gst.gov.in → Search HSN/Service Code. Enter your HSN code and the portal shows the current applicable rate. Don't rely on what you billed last year or what a supplier told you — verify directly. The notification issued by the GST Council in September 2025 is the authoritative source; your CA can pull the specific notification for your HSN.
I raised invoices at 12% on goods now taxed at 18%. What do I do?
Issue a debit note to your customer for the 6% differential and file it in your GSTR-1. You can charge the customer the additional GST if your supply agreement allows for tax changes, or absorb it yourself if not. Either way, the 18% must be remitted to the government — there's no option to pay only what you collected. Interest under Section 50 at 18% per annum runs from the due date of the original return.
Does the zero-mismatch ITC policy mean I can never claim ITC if it's not in GSTR-2B?
You can claim it — but only in the month it appears in GSTR-2B, not the month you received the invoice. If your supplier filed GSTR-1 for October on November 15th, the credit will appear in your November GSTR-2B and you can claim it in your November GSTR-3B. The claim isn't lost; it's deferred until the supplier complies. Keep a pending ITC register to track these.
Is e-invoicing mandatory if my turnover crossed ₹5 crore only this year?
E-invoicing applicability is based on aggregate turnover in any preceding financial year. If your turnover crossed ₹5 crore in FY 2024-25 or FY 2025-26, you must generate e-invoices from April 1, 2026 for all B2B transactions. If you cross ₹5 crore for the first time in FY 2026-27, the obligation typically kicks in from the next financial year — but verify the current CBDT notification as applicability rules have changed with each threshold reduction.
When did you last audit every HSN code in your billing software against the current GST rate notification — and are you certain none of them have moved?
