GST 2.0 Explained: The New 5%/18%/40% Slabs and What Actually Changed

Ask most business owners in Raipur what GST 2.0 means and you'll get some version of "rates changed in September." True, but not the whole picture — and the part that's missing is usually the part that matters for actually running a business. This post is meant to be the starting point: the mechanics of what changed, why, and where to check the number that applies to your specific product rather than relying on a slab you half-remember from a WhatsApp forward.

The 56th GST Council Meeting

The GST Council met on 3-4 September 2025 — its 56th meeting — chaired by Finance Minister Nirmala Sitharaman, and approved what's now widely referred to as GST 2.0. The changes took effect from 22 September 2025, with one notable carve-out: tobacco and pan masala continue at the old 28% plus compensation cess structure until the compensation cess liabilities on those items are fully cleared, at which point they move to the new structure.

For everything else, the old four-slab system — 5%, 12%, 18%, 28% — collapsed into essentially two working slabs, 5% and 18%, with a new 40% de-merit rate reserved for luxury and sin goods (think large SUVs, aerated drinks, tobacco once its cess transition completes). The Council's own framing was that roughly 99% of items previously in the 12% slab moved down to 5%, and about 90% of items previously in the 28% slab moved down to 18%. A small residual set of genuinely high-end or socially discouraged goods moved to 40% instead of 28%, which for those specific items is actually a rate increase, not a cut — worth remembering before assuming GST 2.0 was uniformly a rate-reduction exercise.

What Actually Got Cheaper

A few concrete examples worth knowing, because "GST simplified" is abstract and "this specific thing now costs less" is what a shopkeeper or a customer actually asks about:

Individual life and health insurance moved to nil GST from 22 September 2025 — term plans, ULIPs, endowment policies, and individual/family floater health covers, including senior citizen policies, all dropped from 18% to 0%. Group insurance — the kind an employer buys for staff — stayed taxable at 18%, so this relief is specifically for individual and family policies.

Everyday food and FMCG items that sat in the 12% or 18% brackets mostly landed in 5%: packaged foods, namkeen, biscuits, and several dairy-adjacent products moved down. Cement — a genuinely significant one for anyone building or renovating — dropped from 28% to 18%.

Several essential and already-exempt items stayed at nil, unchanged: this includes unbranded staples that were already outside the tax net before the reform.

Not everything moved down, and this is the part that gets glossed over in casual conversation about the reform. Standard steel and TMT bars, for instance, stayed at 18% — no reduction there despite cement moving down, since steel wasn't sitting at 28% to begin with. And the small set of items that moved to 40% — the de-merit category — actually saw their tax burden rise relative to the old 28% slab.

What a Raipur Trader Should Actually Do

The structural relief is real, but it creates real work in the transition, and the businesses that handle this cleanly are the ones that treat it as a systems update, not just a headline to be aware of.

HSN-wise rate mapping in your billing software. GST is charged based on date of supply, not date of purchase or manufacture — so an invoice raised on or after 22 September 2025 must reflect the new rate regardless of when the stock was procured. If your Tally, Busy, Zoho Books, or custom ERP still has old rate mappings against certain HSN codes, every invoice going out with the wrong rate is a compliance problem waiting to surface at reconciliation or audit. This isn't a one-time fix either — check it against your actual product catalogue, HSN code by HSN code, rather than assuming a blanket "12% became 5%" rule applies cleanly to everything you sell. Some items moved between categories in ways that don't follow the obvious pattern.

Input tax credit on stock held at the transition date. This is the question we get asked most. The good news, and it genuinely is good news: full ITC remains available on inputs procured before 22 September 2025, provided GST was correctly charged and paid at the time of purchase. A rate reduction on a product going forward does not retroactively reduce the ITC you've already claimed or are entitled to claim on stock bought under the old rate. The only scenario requiring ITC reversal is where a supply that was previously taxable became fully exempt after the reform — a genuine exempt-status change, not a mere rate cut. If none of your products moved from taxable to exempt, you likely have nothing to reverse, but it's worth confirming this product-by-product rather than assuming.

Contract and pricing renegotiation. For businesses with standing supply contracts priced inclusive of GST, a rate drop from 18% to 5% on an item changes the effective landed cost meaningfully, and a counterparty may reasonably expect that saving to be reflected. This is a commercial conversation as much as a tax one, and it's better to have it proactively than to have a customer raise it after noticing the rate change on their own.

Finding the Correct Current Rate

General awareness of "we're now on a 5/18/40 system" isn't precise enough to bill correctly. The authoritative source is the CBIC's own GST rates portal (cbic-gst.gov.in), which lists goods and services rates by HSN/SAC code as per the latest notifications. Several private tools and accounting software vendors also maintain updated HSN-wise rate finders that pull from the same notifications, and these are genuinely useful for day-to-day billing lookups — but when in doubt on a specific product, especially a borderline or recently-reclassified item, cross-check against the actual CBIC notification rather than a third-party summary, since summaries lag notifications occasionally and errors do creep in.

One more practical point on the anti-profiteering angle: the formal anti-profiteering mechanism under Section 171 stopped accepting new complaints from 1 April 2025 — before this September reform — with existing cases now handled by the Principal Bench of the GST Appellate Tribunal. Reports suggest the government is considering reviving some form of anti-profiteering oversight specifically to monitor whether businesses pass on the GST 2.0 rate cuts to consumers, though nothing concrete has been notified on that front as of this writing. Businesses that priced products conveniently around the old rate and haven't adjusted downward despite a genuine rate cut should treat this as a live risk area, not a settled one.

This post is meant as the general map. If your business sits in construction, real estate, or rice milling and food processing specifically, the sector-specific posts on this site go into the rate detail that actually applies to your billing.
