Introduction

Ethanol-blended petrol and pure petrol are treated as identical for pricing and taxation purposes, despite being distinct products from a production and tax standpoint. Ethanol is taxed under the GST regime, while petrol remains outside GST and is subject to central excise duty and state VAT. This dual structure has created inconsistencies in price reporting, tax recovery, and fiscal accountability, particularly as blending volumes expand.

Why in the News

India’s ethanol blending programme has scaled up sharply, rising from 1.5% in 2013-14 to nearly 20% by 2025-26, making ethanol a significant component of petrol sold nationwide. Despite this structural shift, fuel pricing disclosures and tax treatment remain unchanged, continuing to reflect 100% petrol. This is a sharp contrast with earlier years when petrol sold was chemically uniform. 

Why Does Ethanol Blending Complicate Fuel Pricing?

1. Distinct Products: Treats ethanol-blended petrol and pure petrol as identical despite different tax regimes.
2. Tax Regime Split: Ethanol falls under GST, while petrol remains outside GST, subject to excise and VAT.
3. Structural Shift: Reflects a major change in fuel composition without corresponding pricing reform.

How Is Ethanol Taxed Compared to Petrol?

1. GST on Ethanol: Levies 5% GST on ethanol used for blending.
2. Excise on Petrol: Applies central excise duty and state VAT on petrol.
3. Non-Recoverable GST: Prevents oil marketing companies from claiming input tax credit as petrol is non-GST.

What Does the Cost Comparison Reveal?

1. Ethanol Procurement Cost: Records a weighted average cost of ₹71.32 per litre in 2024-25, including ex-mill price, GST, and transport.
2. Petrol Base Price: Stands at ₹53.07 per litre before taxes and dealer commission.
3. Post-Excise Petrol Cost: Rises to ₹74.97 per litre after adding central excise duty.
4. Cost Distortion: Makes ethanol appear costlier due to unrecoverable GST, not intrinsic price.

How Is Retail Petrol Price Currently Structured?

1. Base Price: ₹53.07 per litre.
2. Central Excise Duty: ₹21.90 per litre.
3. Dealer Commission: ₹4.40 per litre.
4. State VAT: ₹15.40 per litre.
5. Retail Selling Price: ₹94.77 per litre.
6. Mismatch: Reflects pure petrol despite ethanol blending being standard.

Why Is the Absence of a Blended Petrol Price Build-Up a Concern?

1. No Published Break-Up: Omits ethanol share, procurement cost, and tax incidence.
2. VAT Application: Applies state VAT on the entire blended fuel, including ethanol.
3. Opacity: Obscures effective tax burden and fiscal transfers between Centre and States.
4. Accountability Gap: Prevents assessment of blending’s economic and consumer impact.

Is This a Case of Double Taxation?

1. Core Issue: Not double taxation, but lack of clarity on component-wise taxation.
2. GST-VAT Overlap: Taxes GST-paid ethanol again under VAT when blended.
3. Fiscal Distortion: Treats blended fuel as pure petrol for revenue purposes.

What Are the Benefits of Ethanol Blending?

1. Energy Security: Reduces dependence on crude oil imports by substituting a portion of petrol with domestically produced biofuel.
2. Foreign Exchange Savings: Lowers import bill by replacing imported fossil fuel with indigenous ethanol.
3. Agricultural Income Support: Creates assured demand for sugarcane and foodgrain-based ethanol, stabilising farm incomes.
4. Environmental Outcomes: Lowers carbon monoxide and particulate emissions due to cleaner combustion characteristics.
5. Fuel Supply Diversification: Strengthens resilience of the energy system through diversification of transport fuels.
6. Rural Industrialisation: Supports ethanol distilleries and ancillary industries in rural and semi-urban areas.
7. Climate Commitments: Contributes to India’s Nationally Determined Contributions by reducing fossil fuel intensity.

Way Forward

1. Price Disclosure Reform: Publishes a separate price build-up for ethanol-blended petrol, reflecting ethanol share, procurement cost, and tax treatment.
2. Tax Incidence Clarity: Separates GST-taxed ethanol and excise-taxed petrol components in retail price reporting.
3. Fiscal Coordination: Aligns Centre-State taxation frameworks to reflect blended fuel composition.
4. Input Tax Credit Rationalisation: Addresses non-recoverable GST on ethanol to prevent artificial cost inflation.
5. Regulatory Updating: Revises fuel pricing norms to reflect E20 as the default retail product rather than pure petrol.
6. Consumer Transparency: Enables public access to component-wise fuel pricing to ensure accountability.
7. Policy Evaluation Mechanism: Facilitates assessment of whether ethanol blending lowers costs for the economy and consumers.

Conclusion

Ethanol blending marks a significant advancement in India’s energy transition and import substitution strategy. However, the continuation of petrol pricing and taxation practices designed for a pre-blending era has created fiscal opacity and accountability gaps. Aligning fuel price disclosure and tax treatment with the blended fuel reality is essential to ensure transparency, strengthen cooperative federalism, and enable an evidence-based assessment of ethanol blending’s true economic and consumer impact.

Linkage: The question tests understanding of India’s indirect tax reforms, fiscal federalism, and revenue mobilisation under GST (GS III-Taxation). Petrol’s exclusion from GST, highlighted in the ethanol blending debate, explains the persistence of tax distortions and opaque fuel pricing despite GST reforms.
