Road Tax in India: State-wise Rates, Calculation and Online Payment Guide

Buy the same car in Bengaluru and in Delhi and you will pay noticeably different amounts to put it on the road. Not because the car costs more in one place, but because road tax does. On a Rs 15 lakh car, the gap between a high-tax state and a low-tax one can run past a lakh.

Road tax is usually the single largest addition to a car's price after the car itself, and because each state sets its own, it is also the least understood. This guide explains what it is, who charges it, how it is calculated, and what the major states actually levy, so you can work out your own number before anyone quotes you one.

What Is Road Tax and Who Levies It

Road tax, officially Motor Vehicle Tax, is a charge you pay for the right to use your vehicle on public roads. The money funds the building and upkeep of state road infrastructure.

The crucial point is who levies it. Road tax is a state subject, not a central one. Each state and Union Territory sets its own rates through its own Motor Vehicles Taxation Act, which is exactly why the same car costs different amounts to register in different states. There is no national road tax rate, and there never has been.

This is also why registering a vehicle in a low-tax state to save money does not work in practice. The law requires you to register your vehicle where you reside, and moving it to your home state means re-registering and paying that state's tax anyway. The saving evaporates, and you are left with extra paperwork.

One-Time vs Annual Road Tax Explained

How often you pay depends on the type of vehicle, and mixing these up is a common source of confusion.

Vehicle type	How road tax is paid
Private car or two-wheeler	One-time lifetime tax, covering 15 years from registration
After 15 years (private vehicle)	Renewed, typically every 5 years
Commercial vehicle	Recurring, usually quarterly or annually
BH series registration	Paid in blocks of 2 years, renewable

For most private owners, road tax is a one-time payment made at registration and then largely forgotten for fifteen years. Commercial vehicles work differently, paying on a recurring schedule because they earn from the roads they use. The BH series sits in between, spreading the cost across renewable two-year blocks.

The one-time structure has a hidden implication that matters when you move or sell. Because you paid for the full fifteen years upfront, leaving the state early means you have prepaid for time you will not use there, which is exactly what makes a refund possible. And when you sell within the state, the road tax stays with the vehicle rather than the owner, so the buyer inherits the remaining validity without paying afresh. Understanding that the tax attaches to the vehicle for its lifetime, not to you personally, explains most of the confusion people have about refunds and transfers.

How Road Tax Is Calculated

Road tax is almost always a percentage of your vehicle's ex-showroom price. Which percentage applies depends on several factors that states weigh differently:

• Ex-showroom price: The base on which the percentage is applied. A more expensive vehicle attracts more tax, and most states have higher percentage slabs for higher price bands. A handful of states calculate on the pre-GST price instead.

• Fuel type: Diesel vehicles are usually taxed higher than petrol, often by 1 to 2 percentage points, because they pollute more. CNG sometimes attracts a small rebate.

• Vehicle type: Two-wheelers are taxed at lower rates than cars, and commercial vehicles higher still.

• Engine capacity or price band: Some states slab by price, others factor in engine size, and many combine the two.

• Age of the vehicle: Relevant when re-registering an older vehicle, where the tax is often reduced to reflect depreciation.

Layered on top, many states add their own cesses, such as a road safety cess or an infrastructure cess, calculated on the tax amount. These are easy to overlook and can add a meaningful sum, which is why the headline percentage rarely tells the whole story.

A quick worked example makes the scale concrete. Take a Rs 14 lakh petrol car. In Karnataka, at a 17% slab, the base road tax alone is about Rs 2.38 lakh before its cesses. The identical car in Delhi, at roughly 10%, is around Rs 1.4 lakh. That is close to a lakh of difference on the same vehicle, driven entirely by which side of a state border you register it. When people say a car is cheaper in one city than another, this is usually what they are describing, and it is why the state of registration is one of the biggest single levers on what you finally pay.

State-wise Road Tax Rates: Comparison Table

The table below gives an indicative picture for private petrol cars. Rates change with state budgets and each state layers on its own cesses, so treat these as a guide and confirm your state's current figure before budgeting.

State	Indicative road tax (private petrol car)	Notable extras
Maharashtra	About 11% up to Rs 10 lakh, 12% for Rs 10 to 20 lakh, 13% above. Diesel roughly 2% higher	Road safety cess of about 2% on the tax; flat 20% for company-registered and imported vehicles
Karnataka	About 13% at the lowest band, rising to 17% for Rs 10 to 20 lakh and 18% above Rs 20 lakh	Around 11% infrastructure and road safety cess on the tax, plus a small social security cess. Among the highest in India
Delhi	About 4% up to Rs 6 lakh, 7% for Rs 6 to 10 lakh, and 10% or more above	MCD parking charge, commonly Rs 2,000 to Rs 4,000. Diesel higher
Tamil Nadu	Roughly 12% to 20% across price tiers, steepest above Rs 20 lakh	A fixed road safety tax
Uttar Pradesh	Around 8% up to Rs 10 lakh and 10% above	Relatively simple flat structure
Gujarat, Chandigarh, Himachal Pradesh	Among the lowest, roughly 6% to 8%	Gujarat calculates on the pre-GST price

Two patterns stand out. Karnataka consistently sits at the expensive end once its cesses are stacked on, which is why on-road prices in Bengaluru look steep. Delhi and states like Gujarat and Himachal Pradesh sit at the lighter end. The spread between the cheapest and dearest states can be six times over on the same car.

Because the slabs and cesses shift so much between states, a national average is close to useless for budgeting. Looking up the RTO details for your state gives you the road tax structure and registration charges that actually apply to you, which is the figure you need before you can check any dealer quote. Apps such as CarInfo pull this state by state, so you are comparing against your own RTO rather than someone else's.

How to Pay Road Tax Online via Parivahan

For a new vehicle, the dealer usually handles road tax as part of registration. But you can pay it yourself, and you will need to when re-registering a vehicle brought from another state.

1. Go to vahan.parivahan.gov.in and open Online Services, then Vehicle Related Services.

2. Select your state and RTO and enter your vehicle registration number to log in, verifying with an OTP.

3. Choose the Pay Tax option from the list of services.

4. Review the calculated amount, which the portal works out from your vehicle details and your state's rates.

5. Pay online by net banking, card or UPI, and save the receipt.

6. Keep the payment proof, which you will need for registration, re-registration, or any future refund claim.

Some states run their own transport department portals alongside Vahan, so if your state directs you elsewhere, follow that route. The principle is the same: the tax is calculated from your vehicle details and your state's slabs, and paid online against your registration.

What Happens If Road Tax Is Not Paid

For a new private vehicle, this rarely arises, since the tax is paid at registration and the dealer will not hand over a vehicle that is not registered. But it becomes a live issue in two situations: a vehicle brought from another state that has not been re-registered, and a commercial vehicle whose recurring tax has fallen due.

The consequences of unpaid road tax are real and compounding:

• Penalties and interest: Unpaid tax attracts a penalty, often calculated as a percentage of the overdue amount, and it grows the longer it stays unpaid.

• Detention of the vehicle: Transport authorities can seize a vehicle found operating without valid road tax paid, particularly common at interstate checkposts.

• Blocked RTO services: You cannot transfer ownership, renew fitness, or obtain a No Objection Certificate while road tax dues are outstanding, which becomes a problem the day you try to sell.

The classic trap is the person who drives a car into a new state and keeps using it for months on the original registration without paying the new state's tax. It works until a checkpost or a routine stop catches it, at which point the back tax, the penalty and the hassle all land at once. If you have genuinely moved, re-register and pay promptly, and claim the refund on the old state's tax to soften the double payment.

Road Tax for Cars vs Bikes vs Commercial Vehicles

The three categories are taxed on different logic, and it helps to see them side by side.

• Two-wheelers attract the lowest rates, often in the 6% to 13% range depending on the state and the bike's value, paid once as a lifetime tax.

• Private cars sit in the middle, typically 4% to 20% across states and price bands, also paid once for 15 years, with diesel usually taxed higher than petrol.

• Commercial vehicles are taxed highest and differently, usually on a recurring quarterly or annual basis, and often by seating capacity for passenger vehicles or laden weight for goods vehicles, since they earn from road use.

So a family scooter, a family car and a delivery truck bought at the same price would each carry a different tax, calculated on a different basis and paid on a different schedule.

Exemptions: EVs, Government Vehicles and Persons with Disabilities

Several categories pay reduced or zero road tax, though the biggest of these is quietly changing.

• Electric vehicles: As of 2026, around fourteen states and UTs, including Delhi, Maharashtra, Tamil Nadu and several others, still offer a full 100% road tax waiver on EVs. But the era of blanket exemptions is ending: Karnataka, Kerala and Haryana have moved to tiered EV taxation, and some states now tax higher-priced EVs Check your state's current policy rather than assuming a full waiver.

• Vehicles for persons with disabilities: Specially adapted vehicles for persons with disabilities are exempt or heavily concessional in most states, subject to certification.

• Government vehicles: Vehicles owned and used by government bodies are generally exempt, though the specifics vary.

EV buyers in particular should confirm the position for their state and price bracket before counting on a waiver, because these policies are being revised frequently as EV sales grow and states protect their tax revenue.

Green Tax on Older Vehicles

There is a second levy that catches owners of older vehicles off guard, and it belongs in any honest discussion of road tax: the green tax.

When a private vehicle crosses about 15 years, and a commercial vehicle roughly 8 years, its registration or fitness must be renewed rather than simply running on. At that renewal, most states charge a green tax, a surcharge on older, more polluting vehicles designed to nudge them off the road or into cleaner replacement. It is typically levied as a percentage of the original road tax, commonly in the range of 10% to 50% depending on the state, the vehicle's age and its fuel type, with diesel vehicles usually charged more.

The practical point for a buyer is that the total tax cost of a vehicle is not just the one-time payment at purchase. A vehicle kept well beyond 15 years attracts green tax at each renewal, on top of the fitness and re-registration costs, which is part of why very old vehicles become uneconomic to keep on the road. When you are weighing whether to hold a vehicle past its fifteenth year or replace it, the green tax is one of the numbers that belongs in the calculation.

Documents Required

For a new vehicle, the dealer collects most of this, but if you are paying or re-paying road tax yourself, keep these ready:

• Vehicle Registration Certificate, or the sale invoice for a new vehicle

• Proof of address in the state of registration

• Valid insurance certificate

• Identity proof, such as Aadhaar or PAN

• For re-registration from another state, the No Objection Certificate from the original RTO and proof of road tax paid there, which supports any refund claim

Keep every payment receipt. Road tax proof is needed not only at registration but also if you later move states and want to reclaim the unused portion of a lifetime tax.

FAQs

1. Who decides road tax rates in India?

Each state and Union Territory, through its own Motor Vehicles Taxation Act. There is no national rate, which is why the same vehicle costs different amounts to register in different states.

2. Is road tax a one-time payment?

For private cars and two-wheelers, yes. It is a lifetime tax covering 15 years from registration, renewed after that. Commercial vehicles pay on a recurring basis, and BH series registrations pay in two-year blocks.

3. How is road tax calculated?

Usually as a percentage of the ex-showroom price, with the percentage depending on the price band, fuel type and vehicle type. Diesel is generally taxed higher than petrol, and many states add cesses on top of the base tax.

4. Which state has the highest road tax?

Karnataka is consistently among the highest once its infrastructure and road safety cesses are added, reaching around 18% plus cesses on expensive cars. Kerala and Tamil Nadu are also high on premium vehicles.

5. Which states have the lowest road tax?

States and UTs such as Gujarat, Chandigarh, Himachal Pradesh and some north-eastern states sit at the lighter end, often around 6% to 8%, with a few UTs lower still.

6. Can I register my car in a low-tax state to save money?

Not effectively. The law requires registration where you reside, so bringing the vehicle to your home state means re-registering and paying its tax anyway. The BH series is the legal route for those who genuinely move between states for work.

7. Do electric vehicles pay road tax?

In many states, no. Around fourteen states and UTs still offer a full waiver on EVs as of 2026, but some, including Karnataka, Kerala and Haryana, have moved to tiered taxation. Confirm your state's current policy.

8. How do I pay road tax online?

Through vahan.parivahan.gov.in, under Vehicle Related Services, by entering your registration number, selecting Pay Tax, reviewing the calculated amount, and paying by net banking, card or UPI. Some states use their own transport portals.

9. Why is road tax higher for diesel cars?

Because diesel vehicles generally emit more pollutants, most states levy 1 to 2 percentage points more on them than on equivalent petrol vehicles.

10. What is the BH series and how does its road tax work?

The Bharat series is a registration format for people who frequently move states for work. Instead of the full 15-year tax upfront, it is paid in renewable two-year blocks, and the registration stays valid nationwide without re-registration.

11. Do I get a refund if I move my vehicle to another state?

You can claim a refund of the unused portion of the lifetime road tax paid in your original state, since you must pay tax again on re-registration in the new state. It requires an application with your payment proof and the NOC.

12. Are commercial vehicles taxed the same as private ones?

No. Commercial vehicles are taxed higher and on a recurring schedule, often by seating capacity or laden weight, because they earn revenue from road use, whereas private vehicles pay a one-time lifetime tax.
