GST 2.0 explained: what changed for Indian businesses
The 12% and 28% slabs are gone. New 40% slab for sin goods. Most goods reshuffled to 5% or 18%. Here's the practical impact on your invoices, pricing, and ITC.
On 22 September 2025, India's GST council scrapped the 12% and 28% slabs. The country moved to a four-rate structure — and most businesses are still figuring out the impact on their pricing.
The new structure (effective 22 Sep 2025)
| Slab | What it covers |
|---|---|
| 0% | Essentials, 33 lifesaving drugs, dairy, educational materials, individual health & life insurance |
| 5% | Daily essentials, agriculture, healthcare equipment, packaged food, transport. Most former 12% items moved here. |
| 18% | Most goods & services. Electronics, small cars, motorcycles, appliances, restaurants, software, telecom. Most former 28% items moved here. |
| 40% | Luxury & sin goods only. Premium vehicles, pan masala, aerated drinks, tobacco. Replaces the old "28% + cess" combo with a single rate. |
Why this happened
The old 5-rate system (with cess on top of 28%) was unwieldy. Compliance was complex, classification disputes were endless, and the average effective rate had drifted up. GST 2.0 simplifies — fewer slabs, cleaner classification, and one single rate (40%) for luxury/sin instead of "28% + 12% cess + 17% cess depending on item."
What it means for your business
1. You may need to re-price
If you were selling at 12%, you're now likely at 5% — your selling price can drop by ~6.7% without affecting your margin. Or, you keep prices the same and your margin expands. Most retailers chose the second option for the first quarter; expect competitive pressure to force the first eventually.
2. ITC adjustments
Input Tax Credit calculations need recalibration. If your inputs are still at 18% but your output dropped to 5%, you may have inverted duty structure issues. Plan refunds accordingly. Talk to your CA before next return filing.
3. Invoicing & ERP updates
Every accounting system needs the new rate codes. Tally, Zoho, QuickBooks have all pushed updates — make sure yours is current. Old invoices retain old rates; only invoices dated 22 Sep 2025 onwards use new rates.
4. Contract clauses
Long-term contracts often have "GST as applicable" clauses. Customers may demand price reductions where rates dropped. Don't unilaterally pass on benefits unless contractually required — check each contract.
Quick math examples
A ₹10,000 mobile phone (was 12%, now 18%)
Wait — phones moved up? Yes. Some 12% items shifted to 18%, not 5%. Always verify the specific HSN/SAC code on the GST portal.
- Old: ₹10,000 × 12% = ₹1,200 GST → ₹11,200 total
- New: ₹10,000 × 18% = ₹1,800 GST → ₹11,800 total
A ₹500 packaged food item (was 12%, now 5%)
- Old: ₹500 × 12% = ₹60 GST → ₹560 total
- New: ₹500 × 5% = ₹25 GST → ₹525 total
Customer saves ₹35. Margin opportunity for retailer if they don't pass it on fully.
A ₹5L luxury car (was 28% + cess, now 40%)
- Old: 28% GST + 17% cess (varies) → ₹5L × 45% = ₹2.25L tax → ₹7.25L total
- New: 40% flat → ₹2L tax → ₹7L total
Surprisingly cheaper — the old combined cess made some cars cost more than the new 40%.

GST 2.0 is the biggest indirect tax reform since the original GST rollout in 2017. It's good news for compliance and (mostly) for consumers — but every business has to do the work to get pricing, invoicing and ITC right.
