The Burden of High Taxes on Oil and Gas in India: Absorption Capacity, Economic Impacts, and Future Implications.....

Introduction

India's economy heavily relies on imported oil and gas, with over 85% of its crude oil needs sourced from abroad. This dependency exposes the nation to global price volatility, but the government's taxation framework plays a pivotal role in mitigating or exacerbating these effects. Taxes on petroleum products, including central excise duties and state value-added taxes (VAT), constitute a significant portion of retail prices—often exceeding 50% for petrol and diesel. These high taxes generate substantial revenue for the exchequer but also create a buffer against international price hikes. This discussion explores the extent of these taxes, estimates the price increases they can absorb, analyzes losses to the exchequer from tax adjustments, evaluates demand responses based on price elasticity, and examines repercussions on inflation and economic growth. Drawing from historical precedents, it highlights how such dynamics shape India's fiscal and economic landscape, emphasizing the need for balanced policies in a transitioning energy sector.

Extent of Government Taxes on Oil and Gas

In India, the taxation on oil and gas is multifaceted, involving both central and state levies that significantly inflate retail prices. For petrol, the central excise duty stands at around Rs 13 per liter, while state VAT varies widely—ranging from 1% in Andaman & Nicobar to over 31% in Andhra Pradesh, with an average of about 25% across states. Diesel faces similar treatment, with excise at Rs 10 per liter and VAT averaging 20-22%. Natural gas taxation is lighter, often under GST exemptions for blended forms like compressed biogas (CBG), but crude oil imports attract windfall taxes when prices surge. Overall, taxes account for 55% of petrol's retail price and 50% of diesel's, making fuel one of the highest-taxed commodities.

This structure has evolved, with petroleum products remaining outside the GST regime despite ongoing debates for inclusion at a 28% rate. In the 2026 Union Budget, measures like deferring additional excise on unblended diesel to 2028 and reducing GST on small cars to 18% aim to promote cleaner fuels, but core taxes remain high. The government's strategy uses these levies to stabilize domestic prices: when global crude falls, excise hikes capture the windfall, as seen in multiple increases between 2014 and 2022, boosting excise revenue from Rs 1.7 lakh crore to over Rs 3.3 lakh crore annually.

Estimating Price Hike Absorption and Loss to the Exchequer

Given the high tax component, India's system can absorb significant international price hikes without immediate retail increases. For instance, a 10% rise in global crude (from $80 to $88 per barrel) could be offset by reducing excise by Rs 2-3 per liter, absorbing the hike while keeping pump prices stable. Historical data suggests the tax buffer allows absorption of up to 20-30% global increases before retail adjustments are needed, as taxes form a "cushion" equivalent to $20-30 per barrel in effective pricing.

However, this absorption comes at a cost to the exchequer. When taxes are cut to shield consumers, revenue losses mount. Precedents include the 2021 excise reduction of Rs 13 on petrol and Rs 16 on diesel amid record highs, costing the government Rs 1 lakh crore annually—about 0.45% of GDP. Similarly, in 2025, a Rs 2 per liter excise hike was absorbed by oil companies to offset prior losses on cooking gas subsidies, but prolonged absorption leads to cumulative deficits. If oil prices average $90-100 per barrel in 2026-27, absorbing hikes could result in a Rs 50,000-80,000 crore loss, widening fiscal deficits and straining budgets already burdened by subsidies on LPG and kerosene.

High taxes, while revenue-generative (contributing 2% of GDP), can paradoxically lead to losses if they stifle demand or prompt evasion. Over-taxation has historically reduced state shares, as central cesses (not shared with states) rose from 52% to 60% of oil revenues, depriving states of Rs 2-3 lakh crore since 2015.

Effects on Demand and Future Taxes Considering Price Elasticity

The price elasticity of demand for oil and gas in India is notably inelastic, influencing how price hikes affect consumption and future tax strategies. Long-run price elasticity for crude oil imports is around -0.3 to -0.45, meaning a 10% price increase reduces demand by only 3-4.5%. Short-run elasticity is even lower at -0.2, reflecting limited alternatives like public transport or renewables. Income elasticity, however, is high at 1.2-2.7, indicating demand surges 12-27% for every 10% GDP growth, driven by urbanization and industrialization.

This inelasticity means hikes have muted demand effects: a 20% price rise might cut consumption by 4-6% long-term, but overall demand grows 5-6% annually with 7% GDP expansion. For natural gas, elasticity varies—petrochemicals show higher responsiveness (-1.2 long-run), while essentials like LPG are near-inelastic (0.35).Future taxes could adjust downward if elasticity thresholds are breached, as sustained hikes risk demand suppression. If prices exceed $100 per barrel, demand might fall 5-10%, eroding tax bases and prompting cuts to maintain revenue. Precedents like the 2013-14 gradual diesel deregulation, which phased out subsidies amid elasticity concerns, show governments balancing revenue with demand stability.

Repercussions on Inflation and Growth with Examples and Precedents

Oil price hikes transmit to inflation via higher transport and production costs. A 10% increase adds 0.7-1% to Wholesale Price Index (WPI) and 0.35-0.4% to Consumer Price Index (CPI), with indirect effects amplifying to 1-1.5%. This fuels cost-push inflation, eroding purchasing power, especially for low-income households reliant on diesel for agriculture.

On growth, hikes shave 0.15-0.3% off GDP per 10% rise, widening current account deficits by 0.5% of GDP ($18 billion annually). Asymmetric impacts exist: rises hurt more than falls benefit, as seen in 2026 West Asia tensions spiking Brent to $90+, weakening the rupee to record lows and stoking 0.5-1% inflation while trimming FY27 growth from 7% to 6.5%.Historical examples underscore these effects. The 2008 oil shock (prices over $140) triggered 8-9% inflation and slowed growth to 3.1%, prompting subsidy hikes that ballooned fiscal deficits to 6%. Conversely, 2014-16 price drops allowed tax hikes, boosting revenues and growth to 8%, but over-reliance led to 2020-21 losses from pandemic demand slumps. The 2022 windfall tax on exports recouped Rs 1 lakh crore from excise cuts, illustrating adaptive fiscal tools. These precedents highlight that while high taxes provide short-term buffers, prolonged hikes risk stagflation—high inflation with stagnant growth—as in the 1970s oil crises globally, where India saw 20% inflation and sub-5% growth.

Conclusion

India's high taxes on oil and gas, comprising over half of retail prices, offer a robust mechanism to absorb global hikes, potentially cushioning 20-30% increases without retail spikes. Yet, this incurs exchequer losses of Rs 50,000-1 lakh crore annually during volatility, compounded by inelastic demand that sustains consumption but limits adjustments. Elasticity dynamics suggest future taxes may need rationalization to prevent demand erosion, while inflation (up 0.35-1%) and growth slowdowns (0.15-0.3% per 10% hike) pose ongoing risks, as evidenced by past shocks like 2008 and recent geopolitical flares. Precedents of tax tweaks and subsidies demonstrate adaptive policymaking, but long-term solutions lie in energy diversification—boosting renewables to 50% by 2030—and GST inclusion for uniformity. Balancing revenue, affordability, and sustainability is crucial for India's growth trajectory, ensuring oil taxes fuel progress rather than hinder it.
