GST 2.0 Two-Slab System (5% and 18%): How It Affects Business Pricing

The Government of India introduced GST Reforms 2.0, effective 22 September 2025, restructuring the Goods and Services Tax (GST) framework into a simplified two-slab system of 5% and 18%. While higher effective taxation continues for demerit goods through cess or additional levies, the broader objective is rate rationalisation and classification simplification.

This reform directly affects business pricing. Changes in GST rates require companies to reassess selling prices, margins, tax-inclusive contracts and working capital planning depending on how their products or services are reclassified. 

What are the key changes under GST 2.0?

GST 2.0 replaces the earlier multi-slab structure with a two-tier system of 5% and 18% for most goods and services, while retaining higher effective taxation for specific demerit categories.

Below is a summary of major category-level shifts:

Note: 

• For cigarettes and tobacco, an additional excise duty is levied on top of the 40% GST rate. 
• For pan masala, a new Health and National Security Cess is introduced outside GST.

How the GST 2.0 two-slab system affects business pricing

The impact on pricing depends on product reclassification under the new rate structure.

• Upward rate shifts

If a product moves from 12% to 18%, businesses face a higher output tax liability. Companies must either:

• Increase the final selling price, or
• Absorb the tax differential through reduced margins.

In price-sensitive markets, absorbing the increase may compress profitability. In markets with lower elasticity, the tax burden may be passed on to customers.

• Downward rate shifts

If a product moves from 18% to 5%, businesses may experience:

• A reduction in the final selling price, improving competitiveness, or
• An opportunity to expand margins if prices are maintained

Such decisions depend on competitive pressure, anti-profiteering considerations and brand positioning.

• SKU-level repricing

Rate changes require reassessment at the Stock Keeping Unit (SKU) level. Businesses must:

• Recalculate tax-inclusive Maximum Retail Prices (MRP)
• Review distributor margins and dealer mark-ups
• Update pricing structures where tax is embedded

Even small rate changes affect the tax component within existing price assumptions.

B2B vs B2C impact

The pricing effect differs across business models.

• In B2B transactions, buyers can claim ITC. While demand impact may be limited, working capital cycles and tax outflows may shift.
• In B2C segments, ITC is not available to end consumers. Any rate increase directly influences retail pricing and customer behaviour.

Contractual and commercial implications

Existing contracts may require revision.

Agreements that include tax-inclusive pricing or fixed-price clauses may need renegotiation, especially if rate changes materially alter cost assumptions. Change-in-law provisions become critical in long-term supply arrangements to avoid disputes or margin erosion.

Conclusion

The GST 2.0 two-slab system simplifies the rate structure but redistributes tax incidence across sectors. Some businesses may benefit from lower tax exposure and improved competitiveness, while others may face pricing pressure due to upward rate shifts.

The real impact lies in execution. Businesses that conduct SKU-level tax mapping, update billing systems, review contractual clauses and model pricing scenarios will be better positioned to protect margins and maintain compliance in the revised tax environment.

To adapt smoothly to GST 2.0 rate changes and manage pricing adjustments accurately, businesses should ensure their accounting and GST systems are updated and aligned with the revised structure using solutions like TallyPrime.
