GST Slab Rates Explained Simply: 0%, 5%, 18% and 40%

Bar chart comparing GST on a ₹40,000 product at 28% and 18%

Short answer: India’s GST now has four rates: 0%, 5%, 18% and 40%. Since 22 September 2025 the old 12% and 28% slabs no longer exist. Almost all items from the 12% slab moved to 5%, most items from the 28% slab moved to 18%, and a new 40% rate applies to luxury and sin goods such as tobacco, pan masala and aerated drinks.

The four GST rates today

RateWhat it covers
0%Exempt items and services
5%Essentials and everyday goods. Items that moved here include toothpaste, umbrellas, pressure cookers, sewing machines and bicycles
18%The standard rate for most goods and services. Items that moved here include air conditioners, TVs, refrigerators, washing machines and cement
40%Luxury and sin goods, such as tobacco, pan masala and aerated drinks

The examples above are those reported from the GST Council’s announcement of 3 September 2025. For any specific product, check its HSN code (for goods) or SAC code (for services) on the GST portal, because exact classification matters.

What changed on 22 September 2025

The GST Council abolished two slabs. About 99% of the items in the old 12% slab moved to 5%, and about 90% of the items in the old 28% slab moved to 18%. The idea was to simplify GST and lower prices on many everyday and household items.

What it means for a bill

At 28% (old)₹51,200At 18% (new)₹47,200
A product with a base price of ₹40,000, before and after moving from the 28% to the 18% slab, assuming the base price stays the same.

Take a product with a base price of ₹40,000 that moved from 28% to 18%. At 28%, GST is ₹11,200 and you pay ₹51,200. At 18%, GST is ₹7,200 and you pay ₹47,200. That is ₹4,000 less, if the base price stays the same. In practice, sellers also change prices, so the shelf price may not fall by exactly this amount.

How to calculate GST yourself

  1. Adding GST: GST = base price × rate ÷ 100. Total = base price + GST.
  2. Removing GST from a final price: base price = total × 100 ÷ (100 + rate). For a total of ₹11,800 at 18%, the base price is ₹10,000.
  3. CGST and SGST: inside one state, GST splits equally into CGST (centre) and SGST (state). Between two states, the whole amount is IGST.

The GST calculator does all three, for any amount, at any of the four rates.

Why businesses can claim GST back

GST is a tax on value added at each step, so a business does not pay it twice. It can deduct the GST it paid on its purchases (called input tax credit) from the GST it collects from customers. Take a shop that buys goods for ₹10,000 plus 18% GST, which is ₹1,800. It sells them for ₹15,000 plus 18% GST, which is ₹2,700. The shop pays only the difference to the government: ₹2,700 minus ₹1,800 = ₹900. You, as the final customer, cannot claim this credit, so the full GST on your bill is your cost. This is also why you should ask for a proper GST invoice with the seller’s GSTIN when a business expense is involved.

Common mistakes

  • Using 12% or 28% on a bill dated after 22 September 2025.
  • Applying GST on top of a price that already includes it.
  • Assuming every item in a category has the same rate. Rates depend on the exact HSN or SAC code.
