India GST 2.0 Rate Structure: Changes Effective 22 September 2025
The 56th GST Council meeting introduced GST 2.0 with a streamlined four-tier tax structure effective 22 September 2025. Here is how the new 0%, 5%, 18%, and 40% rates work for Indian businesses and consumers.
On 22 September 2025, following the landmark decisions of the 56th GST Council meeting, India enacted its most comprehensive indirect tax overhaul since the rollout of GST in July 2017. Widely termed "GST 2.0", this restructuring was designed to address long-standing grievances regarding rate inverted duty structures, classification disputes, and the administrative burden of multiple intermediate brackets.
Prior to this reform, the Indian GST architecture relied upon four standard rates (5%, 12%, 18%, and 28%) alongside an array of specialized compensation cesses on automobiles, aerated drinks, and tobacco. Under GST 2.0, the council collapsed the standard tiers into a simplified structure: 0% for essential goods, 5% for standard mass consumption items, 18% as the primary unified slab for services and manufactured goods, and a dedicated 40% rate for demerit and luxury goods that absorbed the erstwhile 28% plus cess structure.
For business owners, chartered accountants, e-commerce merchants, and consumers across India, understanding these revised slabs is vital for maintaining compliant invoicing, updating ERP systems, calculating input tax credits, and accurately pricing inventory.
1. The New GST 2.0 Four-Tier Slab Framework
The central achievement of the September 2025 reform is the phase-out of the 12% and 28% standard brackets. Goods previously taxed at 12% were systematically migrated into either the 5% tier (for consumer staples, processed agricultural products, and entry-level medical supplies) or the 18% tier (for consumer durables, specialized equipment, and mid-range electronics).
Meanwhile, the former 28% bracket, which traditionally attracted an additional compensation cess, was unified into a transparent 40% rate for demerit, luxury, and sin goods. This eliminates the twin calculation of basic GST plus ad-valorem cess on high-end vehicles, tobacco products, and pan masala.
| Tax Slab | Status Under GST 2.0 | Primary Product Categories Included |
|---|---|---|
| 0% (Nil) | Retained & Expanded | Unbranded staples, fresh milk, fruits, vegetables, food grains, educational books, basic healthcare. |
| 5% | Retained & Realigned | Edible oils, packaged tea, spices, apparel below ₹1,000, footwear below ₹1,000, affordable dining, economy passenger transport. |
| 12% | Phase-out / Merged | Items migrated to 5% (essentials) or 18% (processed items). Maintained in software only for prior period invoice reconciliation. |
| 18% | Primary Unified Slab | Commercial services, software, IT, professional fees, restaurants, consumer durables, appliances, industrial raw materials. |
| 28% | Phase-out / Merged | Unified into the new 40% slab or merged down to 18% for essential machinery. |
| 40% | New Unified Demerit Slab | Luxury motorcars, yachts, aerated sweetened beverages, tobacco, cigars, gaming, and demerit goods. |
2. Impact on Everyday Consumer Goods and Services
For households, the restructuring presents a dual impact. Items previously caught in the 12% bracket that moved down to 5% experienced immediate retail price relief. Common processed kitchen ingredients, butter, cheese, and certain diagnostic kits saw an effective tax reduction of 7 percentage points.
Conversely, manufactured durables previously taxed at 12% that migrated to 18% experienced upward price pressure, unless manufacturers utilized the widened input tax credit (ITC) pipeline to offset production expenses. Because commercial services remain at 18%, service sector billing (telecom, banking, SaaS, and consultancy) remained stable without disruptive reclassifications.
3. Invoicing Rules for Existing Contracts and Prior Orders
A common source of confusion among accounts departments is the tax treatment of supplies initiated before 22 September 2025 but invoiced or paid afterwards. Section 14 of the Central Goods and Services Tax (CGST) Act governs the time of supply during rate changes:
Rule A: When goods or services were supplied before 22 September 2025, but the tax invoice is issued and payment received after that date, the applicable rate is the new rate effective on the date of receipt or invoice, whichever is earlier.
Rule B: When both the invoice was issued and payment received prior to 22 September 2025, the old tax rate (such as 12% or 28%) legally applies, even if physical delivery occurs after the effective date.
Because businesses frequently need to generate credit notes, debit notes, or supplementary invoices for purchase orders created prior to September 2025, the UtilityKit GST Calculator retains the legacy 12% and 28% rates under an explicitly labelled historical options toggle.
4. Worked Mathematical Comparison: Old vs New Invoicing
To observe how the calculation differs under the revised framework, consider a commercial supply of premium industrial components formerly taxed at 28% that has transitioned to the unified 18% standard bracket, compared to a luxury consumer product taxed at 40%:
Example 1: Component Base Price = ₹50,000 Old Invoicing (28% GST): Base ₹50,000 + GST ₹14,000 = ₹64,000 GST 2.0 Invoicing (18% GST): Base ₹50,000 + GST ₹9,000 = ₹59,000 Direct Business Saving = ₹5,000 (CGST ₹4,500 + SGST ₹4,500) Example 2: Luxury Automotive Unit Base = ₹15,00,000 GST 2.0 Unified Demerit (40% GST): CGST (20%) = ₹3,00,000 SGST (20%) = ₹3,00,000 Total GST = ₹6,00,000 Total Retail Price = ₹21,00,000 (No separate compensation cess lines required)
- •Invoicing under the 40% slab splits into 20% CGST and 20% SGST for intra-state sales, or 40% IGST across state borders.
- •Ensure your accounting software (Tally, Zoho Books, SAP, Busy) is updated with the revised GST master table.
- •Always inspect your supplier credit notes to ensure historical rates are applied only to pre-transition supply dates.
Frequently Asked Questions
Are the 12% and 28% GST rates permanently abolished?
Under the GST 2.0 rationalization effective 22 September 2025, the standard 12% and 28% slabs have been phased out for new supplies. They remain valid exclusively for historical auditing, prior-period adjustments, and processing credit/debit notes for supplies executed before the transition date.
How does the 40% rate split between Central and State governments?
For intra-state transactions within the same state or union territory, the 40% tax is split equally: 20% Central GST (CGST) and 20% State GST (SGST). For inter-state transactions, the entire 40% is collected as Integrated GST (IGST).
Does the GST 2.0 restructuring alter Input Tax Credit (ITC) eligibility?
The core eligibility criteria under Section 16 of the CGST Act remain unchanged. However, because many input materials previously taxed at 12% now match the 18% output rate of manufactured goods, inverted duty refund accumulation has been substantially reduced for manufacturers.
Summary & Best Practices
The transition to GST 2.0 marks an important step toward a simpler, more predictable tax regime in India. By reducing tax brackets from four standard tiers down to three primary levels (0%, 5%, 18%) plus a dedicated luxury slab (40%), businesses spend less time fighting classification disputes in tax tribunals.
