Crude oil prices are jumping again because of global conflict. It happens every time a missile flies or a trade route gets blocked. You’ve probably seen the headlines asking why India doesn’t just put petrol and diesel under the Goods and Services Tax (GST) to stop the price swings. It sounds like a simple fix. If we just had one tax rate instead of a mess of central and state levies, prices at the pump would drop instantly. Right?
Well, it’s not that easy. In fact, it’s a fiscal nightmare that most politicians don't want to touch with a ten-foot pole.
When war breaks out in the Middle East or Eastern Europe, the global supply chain for crude oil chokes. Brent crude prices spike. For a country like India, which imports more than 85% of its oil, this is bad news for the rupee and even worse for your wallet. But the reason you’re paying nearly 100 rupees a liter isn't just because of the war. It’s because the government uses oil as its personal piggy bank.
The Revenue Addiction Nobody Wants to Quit
State governments and the Center are addicted to oil money. That’s the blunt truth. Right now, petrol and diesel are outside the GST net. This means the Center can slap on a heavy excise duty and the states can add their own Value Added Tax (VAT).
In some states, the total tax component makes up nearly 45% to 50% of what you pay at the petrol pump. If you move oil into the GST, the highest slab is currently 28%. Even if the government adds a "cess" on top of that, they’d still likely lose a massive chunk of revenue. We’re talking about a hole in the budget worth lakhs of crores.
Think about it from a state’s perspective. States like Kerala, Tamil Nadu, or Maharashtra rely on VAT from fuel because they have very few other ways to raise quick cash. Unlike the GST, where the Center collects the money and then redistributes it (often with delays), VAT goes straight into the state’s pocket. They aren't going to give that up without a fight.
How War Highjacks the GST Conversation
War changes the math. When crude oil was at $70 a barrel, the "GST for petrol" debate was a quiet academic exercise. When it hits $90 or $100 because of geopolitical tension, it becomes a political emergency. High oil prices drive up inflation. When it costs more to transport tomatoes, the price of your salad goes up.
The central government knows that high inflation loses elections. So, they feel the pressure to bring oil under GST to "stabilize" things. But the timing is always wrong. If they switch to GST while oil is expensive, they lock themselves into a lower tax revenue during a time when the subsidy bill for things like fertilizers and food is also rising because of—you guessed it—the war.
It’s a trap. They can’t afford to keep taxes high because people get angry. They can’t afford to lower them by moving to GST because the treasury will go dry.
The Complicated Math of Revenue Neutral Rates
If the government actually pulled the trigger, they’d have to figure out a "Revenue Neutral Rate." This is a fancy way of saying a tax rate that ensures the government doesn't lose a single paisa compared to the old system.
Experts from groups like the National Institute of Public Finance and Policy (NIPFP) have looked at this. To keep the current revenue levels, the GST on petrol might need to be as high as 40% or 50%. But wait. The GST law currently caps the top rate at 28%.
To make this work, they’d have to:
- Amend the GST law.
- Create a special "Super Slab" just for fuel.
- Convince every single state in the GST Council to agree.
The GST Council works on consensus. Do you really see every state, regardless of their political party, agreeing to give up their last remaining bit of financial independence? I don't.
Why Oil Companies Are Actually Pro GST
Surprisingly, the big oil marketing companies (OMCs) like IOCL, BPCL, and HPCL are the ones pushing hardest for this change. It’s not because they want you to pay less. It’s because of something called "Input Tax Credit."
Right now, these companies pay GST on everything they buy—steel for pipes, trucks, legal services, and machinery. But since their final product (petrol) isn't under GST, they can’t claim back the taxes they paid on those inputs. It’s a huge "stranded cost" for them. If petrol moved to GST, these companies would save billions. They could potentially pass some of those savings to you, but they’d mostly use it to fix their balance sheets which get hammered every time the government asks them to "absorb" a price hike during an election season.
The Global Reality Check
India isn't alone in this. Look at Europe. Many countries there have massive "green taxes" on fuel. They don't want petrol to be cheap because they want people to buy EVs.
In India, the high tax on petrol is basically a luxury tax that funds social welfare programs. It’s a messy, inefficient way to do it, but it works for the government. If they lower the tax on petrol, they’ll just have to raise it on something else. Would you rather have cheaper petrol or a higher GST on your phone, your clothes, and your Netflix subscription? Because the money has to come from somewhere.
The Inflation Domino Effect
Let's talk about what happens when the war in the Middle East actually stops. Usually, oil prices tank. If petrol were under GST during a price crash, the government would be stuck with a fixed percentage of tax.
Under the current system, when global oil prices fall, the government often raises the excise duty. This keeps the price for you the same, but the government pockets the difference. It’s a cynical move, but it’s how they managed to keep the economy afloat during the pandemic years. GST would take away that "cushion." It would force the government to be more disciplined with their spending. And if there’s one thing governments hate, it’s being told how to spend their money.
What You Should Watch For
Don't expect a sudden shift to GST tomorrow. Instead, watch the "compensation cess" debates in the GST Council. If the Center finds a way to guarantee states their income for another five or ten years, the states might stop complaining.
Also, watch the crude oil benchmarks. If Brent stays above $90 for more than a quarter, the political heat will become unbearable. At that point, the government might do a "GST-Lite"—maybe putting natural gas or aviation turbine fuel (ATF) under GST first as a test case. They’ve already talked about doing this for ATF because airlines are struggling.
How to Protect Your Own Finances
Since you can't control the war or the GST Council, you have to play the game differently.
- Stop tracking daily price changes. It’s a waste of mental energy. The price is going to stay high because the structural tax problem isn't going away.
- Look at the fuel-weighted inflation. If you're a business owner, start baking a 10% annual increase in transport costs into your margins now. Don't wait for the next war to react.
- Understand the "Special Additional Excise Duty." This is what the government uses to tax "windfall profits" of domestic oil producers when global prices are high. It’s another reason why they don't want GST—it’s easier to just slap a new duty on top of the existing mess whenever they need cash.
The war-oil-GST triangle is a mess of geopolitics and greed. While the "One Nation, One Tax" slogan sounds great on a billboard, it dies a slow death in the accounting rooms of the Ministry of Finance. For now, the best thing you can do is realize that the price at the pump is a political choice, not just a market reality.
If you’re waiting for GST to save your fuel bill, you’re going to be waiting a long time. Focus on your own fuel efficiency and business logistics. The government isn't giving up its oil addiction anytime soon.
