The biggest overhaul of India’s GST system since 2017 happened quietly for most businesses. The rates changed. The slabs changed. And many businesses still haven’t verified whether their own products and services are correctly classified.
GST 2.0 took effect on 22 September 2025. The old four-slab structure — 5%, 12%, 18%, and 28% — was replaced with three slabs: 5% for essentials, 18% as the standard rate, and 40% for luxury and sin goods. The 12% slab no longer exists.

Quick Summary — What Changed on 22 September 2025
| Old Slab | New Position |
| 0% (Nil) | Remains — more items added (UHT milk, bread, life/health insurance) |
| 5% | Remains — many 12% items moved down here |
| 12% | Eliminated — goods moved to 5% or 18% |
| 18% | Remains — most standard goods and services |
| 28% + Cess | Eliminated for most goods — replaced by 40% single rate |
| 40% (New) | Luxury vehicles, aerated drinks, tobacco, casinos, IPL tickets |
💡 TaxKitab Tip The biggest GST filing mistake after a rate change isn’t the rate itself — it’s using the old rate on invoices issued after the effective date because nobody updated the billing software in time. Check every HSN code in your software against the new rate structure. One wrong rate on a B2B invoice means your buyer can’t claim correct ITC, and you may face a demand for the difference. — From our GST Filing Mistakes Guide (Book 1).

Why the 12% Slab Disappearing Matters More Than People Realize
Thousands of products sat at 12%. Most moved down to 5%. Some moved up to 18%. If your product was at 12% and you haven’t verified where it landed, you’re either overcharging customers (charging 18% on something now at 5%) or undercharging the government (charging 5% on something that moved to 18%). Both create problems. Overcharging erodes customer trust. Undercharging creates a tax liability you’ll eventually owe with interest.
What Moved to 5% (From 12%)
Packaged food items, agricultural equipment, hotel accommodation under ₹7,500 per night, processed foods (jams, juices, butter, ghee, dry fruits), footwear under specified thresholds, certain construction materials, and several healthcare products. Check your specific product category against the updated CBIC notification — don’t rely on a summary list alone.
What Moved to 18% (From 12%)
Clothing above ₹2,500 per piece, certain man-made fibres, and several goods that previously had concessional rates. If your business deals in any category that sat at 12% and you assumed “it moved to 5%,” verify this specifically — not everything went down.
What the New 40% Rate Covers
Aerated and caffeinated drinks, luxury vehicles above specified thresholds, motorcycles above 350cc, private aircraft, yachts, casinos, gambling, online gaming at specified value, and IPL event tickets. This replaced the old 28% + compensation cess structure for most of these categories.
Three Things Your Business Must Have Done by Now
- Updated billing software — every invoice issued after 22 September 2025 must use the new rate. Any invoice with the old 12% or old 28%+cess structure for affected goods needs correcting.
- Reviewed inventory valuation — goods in stock before 22 September 2025 that were supplied after that date have a different tax incidence. This transition stock needs specific accounting treatment.
- Checked ITC position — if you were claiming ITC on inputs now nil-rated, that credit may need reversal. A mere rate reduction doesn’t automatically require ITC reversal, but nil-rating does.
Frequently Asked Questions
Does GST 2.0 change GST registration thresholds?
No. The turnover-based registration thresholds (₹20 lakh for services, ₹40 lakh for goods in most states) are unchanged by this rate reform.
If my product moved from 12% to 5%, do I have to reverse ITC on old stock?
Not automatically. ITC reversal is required where supplies become exempt — not where the rate merely reduces. If your product remains taxable at the new 5%, previously availed ITC on inputs stays valid. Confirm this for your specific product with a professional before reversing.
Does the 40% rate include cess on top?
For most goods in this category, the 40% rate replaces the old 28% + compensation cess structure. Tobacco and related products are an exception — cess continuation there depends on discharge of the compensation cess debt, which the government indicated would happen before December 2025. Verify current position for tobacco-specific products at cbic.gov.in.
Is GST 2.0 fully implemented or are there more phases?
The rate rationalization is largely implemented as of September 2025 and the Budget 2026 amendments effective April 2026. The ITC hard-locking mechanism (tying ITC to IMS-confirmed invoices only) was the next major enforcement step, targeting around July 2026.

⚠️ Rate changes are product-specific. Don’t rely on general category descriptions — verify your exact HSN code against the CBIC rate notification at cbic.gov.in before updating invoices.
This rate change works directly alongside the new Invoice Management System we cover in our IMS guide — because getting your output rate right in GSTR-1 now feeds directly into your buyers’ IMS dashboard and their ITC eligibility.
