GST Rate Slabs in 2026 After the GST 2.0 Reform

The GST rate slabs in 2026 are simpler than they were a year ago: most goods and services now sit in just two bands, 5% and 18%, alongside a 0% exempt category and a new 40% rate for a short list of luxury and sin goods. This is the result of the "GST 2.0" rate rationalisation that took effect on 22 September 2025, which collapsed what had been a four-slab system into something much closer to two.

What the GST 2.0 reform actually changed

The Goods and Services Tax has run on a multi-slab structure since it launched, with different categories of goods and services taxed at different rates depending roughly on whether they were treated as essential, standard, or discretionary consumption. The reform Council decided the structure had become too complex — too many borderline classification disputes, too many products sitting awkwardly between slabs — and voted to simplify it dramatically. That decision was made at the 56th GST Council Meeting, held on 3 September 2025 in New Delhi under Finance Minister Nirmala Sitharaman, and it is generally referred to in the press as "GST 2.0" or the GST rate rationalisation.

The new rates became effective from 22 September 2025 for goods and most services. That is the date your invoices, price lists and accounting entries should reflect for anything other than tobacco, which is discussed separately below.

The old four-slab structure

Before the reform, GST on goods and services was organised around four principal rates, with a 0% exempt category sitting outside them and compensation cess layered on top of the 28% slab for specific categories such as automobiles, tobacco and aerated drinks.

The new structure from 22 September 2025

GST 2.0 essentially removed the 12% slab and thinned out the 28% slab, redistributing most of what sat in those bands into 5% and 18% respectively. A new 40% de-merit rate was introduced to catch the small residue of genuinely luxury or sin goods that would otherwise have lost the compensation-cess top-up when 28%-plus-cess was retired.

The direction of travel is the important thing to internalise even if you never memorise the exact percentages: the middle of the old structure (12%) has essentially been absorbed into 5%, the bulk of the top of the old structure (28%) has been absorbed into 18%, and only a narrow top slice now sits at 40%. Food saw the most extensive rationalisation of any sector, consistent with the Council's stated aim of reducing GST on everyday consumption.

Sector notes worth knowing

Food was the sector most visibly affected by the reform, and the exemption of items such as milk, paneer and roti was widely reported as a headline outcome of the 56th Council Meeting — consistent with the broader goal of lowering the tax burden on everyday consumption. At the other end, aerated beverages and other luxury consumables were specifically called out as moving to the new 40% de-merit rate rather than settling at 18% with the rest of the former 28% bracket. Beyond these two examples, this article deliberately does not attempt to enumerate a full sector-by-sector rate table — the underlying notifications run to hundreds of HSN/SAC line items, and a general blog post is the wrong place to substitute for reading the notification that actually applies to your product.

The tobacco carve-out

Cigarettes, chewing tobacco, zarda, unmanufactured tobacco and beedi were explicitly excluded from the 22 September 2025 rate change. These products continued at their pre-reform rates with compensation cess still applied, rather than moving to the new 5/18/40 structure with everyone else. The reported reason is that compensation cess collections on tobacco are tied to repaying loans taken to cover states' revenue shortfall during the compensation-cess era, and the Council chose not to disturb that revenue stream until those obligations are cleared.

As of publication, the exact date on which tobacco products will transition to the new structure is unresolved and was not something we could independently confirm. If tobacco is relevant to your business, treat this as an open item and check the current notification status on cbic-gst.gov.in before billing — do not assume the general 22 September 2025 rate change applies to these products.

What it means for invoicing and billing software

Practically, a rate change of this scale touches every system that has a GST rate hardcoded against an HSN or SAC code — invoicing tools, ERP rate masters, e-commerce checkout logic, and any spreadsheet-based pricing model. A few things worth checking:

• Any rate master that maps HSN/SAC codes to a GST percentage needs to be refreshed against the current notification, not assumed to still show 12% or 28% for items that have moved.
• Invoices raised on or after 22 September 2025 for goods and services covered by the reform should use the new rate; invoices for the tobacco carve-out items should not, until a further notification changes that.
• If your GSTR-1 and GSTR-3B filings pull rates from the same master your invoicing system uses, a stale rate master will produce a mismatch between what you billed and what you report — worth reconciling against your GSTR-1 and GSTR-3B filing calendar for the first return cycle after the change.
• If you are running the composition scheme, note that composition rates are a separate mechanism from the standard slabs discussed here — see our guide to the GST composition scheme for those rules.
• Price lists, quotations and standing contracts that quote GST-inclusive pricing may need reissuing if the underlying rate moved, since a stale quote can under- or over-collect tax without anyone noticing until reconciliation.
• If you sell across multiple HSN/SAC codes, spot-check a sample of your catalogue against the new notification rather than assuming a single bulk update caught every line — mixed-rate catalogues are where rate-master errors tend to hide.

None of this is a one-time task. Rate masters drift over time as new SKUs are added, and a rate change of this size is a natural trigger to build a periodic rate-audit step into your regular compliance routine rather than treating 22 September 2025 as a single fix-it-once event.

Why the Council made this change

The stated rationale behind GST 2.0, as reported around the 56th Council Meeting, was that the four-slab structure had accumulated years of classification disputes — businesses and tax authorities disagreeing over whether a given product belonged in the 12% or 18% bucket, or the 18% or 28% bucket, often for reasons that had more to do with how a product was described than what it actually was. Collapsing the structure toward two dominant slabs was intended to reduce that friction and make the system easier to administer and comply with, alongside the more visible goal of lowering tax on everyday consumption items. The same Council meeting is also reported to have recommended steps to operationalise the GST Appellate Tribunal and streamline refund processes — separate strands of the same broader simplification push, though not part of the rate structure itself.

ITC on transitional stock

A rate change also raises the practical question of what happens to input tax credit sitting on stock that was purchased under the old rate but sold under the new one. This is a standard transitional-provisions question that arises whenever GST rates move, and the mechanics depend on notification-specific transitional rules issued alongside the rate change rather than on the general ITC framework alone. If you are carrying meaningful inventory across the 22 September 2025 cut-off, this is worth a direct conversation with a tax professional rather than a generic rule of thumb — the broader ITC eligibility conditions that apply regardless of the rate change are covered in our input tax credit rules guide.
