What is GST 2.0?

GST 2.0 refers to the comprehensive rate rationalization proposed by the GST Council, simplifying the current 5%, 12%, 18%, 28% structure into a cleaner three-slab system: 5% (essentials), 18% (standard), and 40% (luxury/sin goods).

Current vs Proposed Structure
GST transformation
Current (Pre-Sept 2025)GST 2.0 (Post-Sept 2025)
0%, 5%, 12%, 18%, 28%
5%, 18%, 40%
Complex product classificationSimplified categories
Frequent rate confusionClear three-tier logic

Product Reclassification: What Moved Where

5% Slab (Essentials)

  • • Food grains, milk, eggs (no change)
  • • Healthcare products, medicines
  • • Educational materials, books
  • NEW: Some items moved from 12% (edible oils, tea, coffee)

18% Slab (Standard Goods & Services)

  • • Most manufactured goods (no change)
  • • All services (IT, consulting, professional)
  • NEW: Items moved UP from 12% (processed foods, textiles)
  • NEW: Items moved DOWN from 28% (consumer electronics, two-wheelers)

40% Slab (Luxury & Sin Goods)

  • • Tobacco, cigarettes (moved from 28% + cess)
  • • Luxury cars above ₹15 lakh
  • • Premium alcohol (state VAT + GST)
  • • High-end electronics (gaming consoles, luxury watches)

B2B vs B2C Pricing Impact

B2B Impact

Positive:

  • • Full input tax credit (ITC) available
  • • Rate changes = neutral (claim output against input)
  • • Simplified compliance with 3 slabs

Watch Out:

  • • Inverted duty structure if input > output rate
  • • Working capital impact during transition

B2C Impact

Negative:

  • • No ITC = bear full GST burden
  • • Items moved from 12% to 18% = 6% price hike
  • • Luxury goods 28% → 40% = 12% increase

Positive:

  • • Some electronics 28% → 18% = cheaper
  • • Edible oils 12% → 5% = relief

Industry-Specific Impact Analysis

FMCG & Retail

Mixed impact: processed foods see 12% → 18% hike, but edible oils get relief (12% → 5%). Expect repricing across product lines.

Textiles & Apparel

Negative: Most garments move from 5%/12% → 18%. Industry concerns about competitiveness vs China/Bangladesh.

Electronics & Consumer Durables

Positive: Smartphones, TVs, laptops drop from 28% → 18%. Expected sales boost of 15-20%.

Automobiles

Two-wheelers & entry cars: 28% → 18% (huge relief). Luxury cars (₹15L+): 28% → 40% (12% hike).

IT & Services

No change: Services remain at 18%. Simplified compliance with fewer rate categories.

Input Tax Credit (ITC) Implications

Inverted Duty Structure Risk

Problem Scenario:

Textile manufacturer buying cotton yarn (5%) to make garments (18%)

  • • Input: ₹100 + ₹5 GST = ₹105
  • • Output: ₹150 + ₹27 GST = ₹177
  • • ITC claim: ₹5
  • • Net GST payable: ₹22
  • No issue – normal flow

Inverted Duty (Rare but Exists):

Manufacturer buying input at 18%, selling output at 5%

  • • ITC accumulates (input GST > output GST)
  • • Refund claims increase
  • • Working capital blockage

Transition Strategies for Businesses

1. Inventory Management (July-August 2025)

  • • Products moving 28% → 18%: Stock up before Sept 1
  • • Products moving 12% → 18%: Clear inventory by Aug 31
  • • Avoid excess stock of rate-increasing items

2. Pricing & Contracts

  • • Update price lists by Aug 15
  • • Renegotiate long-term contracts with GST variation clauses
  • • Communicate changes to B2B clients in advance

3. Accounting Software Updates

  • • Coordinate with software vendor for rate table updates
  • • Test invoicing system with new rates (dry run)
  • • Train accounts team on revised HSN-rate mapping

4. Compliance Readiness

  • • File GSTR-1/3B for August by Sept 10 with old rates
  • • First invoice on Sept 1 onwards = new rates
  • • Monitor ITC mismatches due to rate changes

Common Questions Answered

Q: What about stock purchased at old rate, sold at new rate?

You charge new GST rate on sale date. Input credit at old rate still applies. Net impact depends on rate increase/decrease.

Q: Do I need to file any special transition form?

Likely yes – similar to TRAN-1/2 in 2017. GST Council will notify transition provisions by July 2025.

Q: How will e-way bills work during transition?

E-way bills generated before Sept 1 with old rates remain valid. New generation from Sept 1 = new rates.

Timeline to Watch

June 2025: Final GST Council approval & notification

July 2025: Detailed HSN-wise rate list published

August 2025: Transition provisions, software updates, business preparation

September 1, 2025: GST 2.0 goes live

Conclusion

Big Change Coming
Prepare for GST 2.0

GST 2.0 is the most significant tax reform since 2017's GST rollout. While the three-slab structure simplifies compliance, businesses must prepare for pricing adjustments, inventory strategy, and system updates. Winners: electronics and automobile buyers. Losers: textile and processed food consumers. Start planning now – transition begins in 120 days.
