GST Rate Structure — Understanding the GST 2.0 Slabs


GST rates aren't fixed forever — they get revised by the GST Council from time to time based on economic conditions and policy priorities. The biggest change so far came with the 'GST 2.0' reform, effective from 22nd September 2025, which dramatically simplified the rate structure. This guide walks through the new slabs, what moved where, and how to find the exact rate for any product.

From Four Slabs to Two — The GST 2.0 Reform

Until September 2025, GST had four main slabs — 5%, 12%, 18% and 28% — plus a compensation cess applicable on select items like automobiles, tobacco, and aerated drinks. This structure had grown increasingly complex over the years, with frequent classification disputes over which slab a given product belonged to.

Following the 56th GST Council meeting held on 3rd September 2025, the Council approved what is commonly referred to as 'GST 2.0' or the 'Next-Gen GST reforms' — the most significant rate overhaul since GST was introduced in 2017. The revised rates came into effect on 22nd September 2025 for most goods and services (a few tobacco-related items continue under the older rate and cess structure until a separately notified later date).

The New Slab-Wise Structure

•      0% (Nil-rated): essentials like fresh food, milk, life-saving drugs, educational services, and — as a major relief measure — individual health and life insurance premiums, which were earlier taxed at 18%

•      5% (Merit rate): everyday essentials, packaged food, agricultural inputs, and daily-use items such as soaps, shampoo, toothpaste and toothbrushes (many of which were earlier taxed at 18%, and some previously at 12%)

•      18% (Standard rate): the default rate covering most goods and services, including items that moved down from the old 28% slab, such as small cars, two-wheelers up to 350cc engine capacity, cement, and most consumer electronics and appliances

•      40% (Demerit/Special rate): a new, higher rate for luxury and 'sin' goods — pan masala, tobacco products, aerated and caffeinated beverages, large passenger vehicles and motorcycles above 350cc, yachts, personal aircraft, and online money gaming, casinos, betting and lotteries — effectively replacing the earlier 28% + compensation cess combination on these items

•      Special niche rates: 3% on gold, silver, and finished/imitation jewellery; 0.25% on rough diamonds and unworked precious stones — both of these continue largely unchanged from the earlier structure

What Got Cheaper and What Got Costlier

•      Cheaper: household essentials like soap, shampoo, toothpaste and hair oil (18%→5%); small cars and two-wheelers up to 350cc (28%+cess→18%); cement (28%→18%); many packaged foods (12%→5%); individual health and life insurance (18%→Nil); several lifesaving drugs and cancer/rare-disease medicines

•      Costlier: pan masala, tobacco, aerated/caffeinated drinks, large luxury vehicles, motorcycles above 350cc, yachts, personal aircraft, and online money gaming/casino/betting services, all of which moved up to the new 40% demerit slab

Where to Verify the Exact Rate

The most reliable way to confirm the GST rate applicable to a specific product or service is to match its HSN code (for goods) or SAC code (for services) against the latest official CBIC rate notification — a general category description alone can be misleading, since a mixed or composite product can sometimes fall into a different slab than expected. Using the wrong rate after 22 September 2025 (for example, invoicing at the now-abolished 12% slab) is treated as an error and can attract penalties under Section 122 of the CGST Act.

💡  Illustration — Everyday Item Rate Change

Before GST 2.0, a bottle of shampoo attracted 18% GST and a small car attracted 28% GST plus compensation cess. After the 22 September 2025 reform, the shampoo is taxed at just 5%, and the small car at a flat 18% (no separate cess) — a meaningful price reduction for consumers on both.

💡  Illustration — Demerit Goods Rate Change

A pack of pan masala, which earlier attracted 28% GST plus a steep compensation cess (pushing the effective rate well above 60% for some tobacco products), now attracts a flat 40% GST rate under the new demerit slab, with valuation for certain items now based on Retail Sale Price (RSP) rather than transaction value, to curb undervaluation.

⚠  Common Mistakes to Avoid

•  Continuing to bill at the old 12% or 28% rates on outdated invoicing templates or ERP settings after 22 September 2025

•  Assuming a product's rate based on its broad category alone, rather than checking its specific HSN code classification

•  Overlooking that cess-inclusive comparisons from before the reform (like the old 28%+cess on cars) don't map cleanly to a single new rate — the actual comparison should be done item by item

•  Not renegotiating existing B2B contracts where the underlying GST rate has changed, leading to disputes over who bears the rate difference

Frequently Asked Questions

Q1. How many GST rate slabs exist today?

A. Mainly two working slabs — 5% and 18% — plus a 40% rate for demerit/luxury goods, and niche rates of 3% and 0.25% for precious metals/stones.

Q2. Who decides GST rates?

A. The GST Council, based on recommendations of its Fitment Committee, decides rates, and changes are notified by the Central and State governments through official notifications.

Q3. When did the new GST 2.0 rates come into effect?

A. 22nd September 2025, for most goods and services, following approval at the 56th GST Council meeting on 3rd September 2025 — though a few tobacco-related products continue under the older rate/cess structure until separately notified.

Q4. How can I check the exact GST rate for a specific product?

A. The most reliable way is to match the product's HSN (for goods) or SAC (for services) code against the latest official CBIC rate notification, since rates are notified item-wise, not just by broad category.

Q5. What happened to the compensation cess after GST 2.0?

A. For most items, the compensation cess has been subsumed into the new consolidated 40% demerit rate, though the compensation cess mechanism itself continues to apply to specified tobacco products until a separately notified date.

Q6. Did GST 2.0 change composition scheme rates too?

A. No — the composition scheme rates (1% for goods traders/manufacturers, 5% for restaurants, 6% for other services) remained unchanged; GST 2.0 primarily restructured the regular rate slabs.

✓  Key Takeaways

•  GST 2.0, effective 22 September 2025, simplified the old four-slab structure (5/12/18/28%) into mainly two slabs — 5% and 18%

•  A new 40% demerit rate now covers luxury and sin goods, replacing the earlier 28% + cess combination

•  Nil rate now covers individual health and life insurance, along with essentials and lifesaving drugs

•  Always verify the current rate against the specific HSN/SAC code via official CBIC notifications rather than assuming based on category

Note: GST rates, thresholds and procedures are revised periodically by the GST Council and CBIC.
