In September 2025, India's GST Council did something it had been debating for years — it simplified the slab structure. The 12% slab that caused endless confusion was abolished. The 28% luxury slab was replaced with a broader 40% rate for sin and luxury goods. And suddenly, a tax system that had seven effective rates now had four clean ones.
For millions of Indian shop owners, this was both relief and panic. Relief, because fewer slabs should mean simpler accounting. Panic, because existing software, price lists, and invoices all needed updating overnight.
This guide tells you exactly what changed, what it means for your shop, and how to update your billing without missing a beat.
The Old GST Slabs (Pre-September 22, 2025)
- 0% — Essential goods (unprocessed food, life-saving medicines)
- 5% — Basic necessities (processed food, transport)
- 12% — Standard goods (processed food, business services)
- 18% — Most goods and services
- 28% — Luxury and sin goods (cars, tobacco, aerated drinks)
Plus special rates of 3% (gold, jewellery) and 0.25% (rough diamonds).
The New GST Slabs (Effective September 22, 2025)
- 0% — Same as before: fresh produce, unbranded food, life-saving drugs
- 5% — Expanded: now includes most items that were at 5% AND many items that were at 12%
- 18% — Standard rate: most items previously at 18%, plus some 12% items that moved up
- 40% — New luxury/sin rate: items previously at 28% (cigarettes, SUVs, aerated beverages)
- 3% — Gold, silver, jewellery (unchanged)
- 0.25% — Rough diamonds (unchanged)
What Moved Where: A Quick Reference for Shops
Items that moved from 12% to 5%:
- Most packaged namkeens and snacks
- Branded ready-to-eat foods
- Basic medicines (non-life-saving category that was at 12%)
- Notebooks and stationery (basic)
Items that moved from 12% to 18%:
- Processed meat and seafood (branded)
- Certain textile fabrics above ₹1,000/metre
- Mobile phone accessories (some categories)
Items at 40% (new, were at 28%):
- Pan masala and gutka

- Aerated drinks and caffeinated beverages
- Luxury cars and SUVs (above ₹10 lakh)
- Yachts, helicopters, private aircraft
Impact on a Kirana Store
For the average kirana store, the practical impact is relatively limited. Most grocery items were already at 0% or 5%. However, if you sell packaged snacks or branded namkeens, check whether they moved from 12% to 5%. If so, good news — your tax liability drops, and you can pass on some savings to customers.
Impact on Electronics and General Stores
Electronics shops need to be careful. Some accessories that were at 12% have moved to 18%. Update your product price list and make sure your billing software has the correct HSN codes mapped to new rates. An incorrect rate on a B2B invoice can cause GSTR-2A/2B mismatches for your buyer — which can trigger a notice.
Impact on Pharmacies
Pharmacies selling life-saving medicines remain at 0% or 5%. Some medicines that were at 12% have moved down to 5% — meaning lower tax, lower prices, and happier customers. However, certain nutritional supplements and cosmetics that were at 12% may have moved to 18%. Cross-check with your distributor's new price list.
How to Update Your ZeroBillBook Account
If you are using ZeroBillBook, the new GST rates are already reflected in the system. Here is what you need to do:
- Go to Products → Edit for any product that was at 12% or 28%
- Select the new correct GST rate from the dropdown (which now shows 0%, 5%, 18%, 40%)
- Save. All future invoices will use the new rate automatically.
We recommend reviewing your top 20 products first — those are the ones most likely to affect your GSTR-1 filings.
The Bigger Picture
GST 2.0 is a sign that India's indirect tax system is maturing. Fewer slabs mean less complexity, fewer errors, and faster reconciliation. For small business owners, the best response is simple: update your software, review your product rates, and keep billing. The fundamentals have not changed — you still need to file GSTR-1 and GSTR-3B on time, and you still need accurate invoices.
The good news? With free tools like ZeroBillBook, keeping up with GST changes has never been easier. The software updates automatically. Your invoices stay compliant. And you can focus on what you do best — running your business.
