How Our Car Tax Calculator Works in India
Our car tax calculator India 2026 provides instant, accurate estimates of all taxes applicable when buying a car in India. Simply select your state, enter the vehicle's ex-showroom price, choose the fuel type and vehicle category, and the calculator will show you exactly how much GST, road tax, and cess you will pay — before you visit a dealership.
The calculator covers all 36 states and union territories in India and uses the latest GST slabs, state road tax rates, and green tax schedules as of April 2026. It is updated whenever state transport departments revise their road tax slabs or the GST Council announces changes to automobile tax rates.
What the Car Tax Calculator Estimates
The calculator provides a comprehensive tax breakdown including GST (central goods and services tax at 5-28% depending on vehicle category), road tax (state-level tax ranging from 3% to 15% depending on state and price bracket), compensation cess (for SUVs and luxury vehicles), and green tax estimate for vehicles over 10 years old.
It also shows the total on-road cost comparison — ex-showroom price plus all taxes — so you can compare the true cost of different vehicles in different states.
Who Should Use This Car Tax Calculator
If you are buying a new car and comparing quotes across states, the car tax calculator helps you understand whether registering in your home state is cheaper than registering where the dealership is located. If you are choosing between variants — a INR 9.9 lakh car versus an INR 10.1 lakh car — the calculator shows whether the price threshold difference pushes you into a higher road tax bracket.
For buyers considering an electric vehicle, the calculator shows the GST savings and road tax exemptions available for EVs compared to equivalent petrol or diesel vehicles, making the total cost of ownership comparison much clearer.
Car Tax Calculator — Sample Results for 2026
Here are typical results from the car tax calculator for a INR 10 lakh (ex-showroom) mid-size petrol car: Maharashtra — GST INR 1,80,000 + Road Tax INR 60,000 = Total Tax INR 2,40,000; Karnataka — GST INR 1,80,000 + Road Tax INR 1,00,000 = Total Tax INR 2,80,000; Delhi — GST INR 1,80,000 + Road Tax INR 60,000 = Total Tax INR 2,40,000; Gujarat — GST INR 1,80,000 + Road Tax INR 30,000 = Total Tax INR 2,10,000.
For the same car as an electric vehicle, all states show significantly lower tax — GST drops to INR 50,000 (5% on INR 10 lakh), and road tax is either zero or heavily subsidised for EVs, bringing the total tax to INR 50,000-80,000 instead of INR 2.1-2.8 lakh.
Limitations of Online Car Tax Calculators
While our car tax calculator provides accurate estimates based on official rates, the actual tax amount confirmed at the RTO may vary slightly depending on your specific vehicle variant, any dealer discounts that affect the declared price, additional accessories or packages added to the vehicle's on-road price, and any green tax orcess applicable to the vehicle's age and category.
Always use the calculator's estimate as a planning tool and confirm the final amount with the dealership or at the RTO before making your budget calculations.

Road tax rates in India vary by state and vehicle category. For new cars, GST is charged at 5% for EVs, 18% for hybrids under 1,200cc, and up to 28% for petrol/diesel SUVs. State road tax is charged separately and varies from Rs3,000-15,000 annually depending on the state's slab system. Check your specific state's RTO website for current rates.
Q: How do I calculate my car road tax online in India?
You can calculate your car road tax using online calculators available on state RTO portals and CarTax.online. The calculation considers your vehicle's ex-showroom price, fuel type, engine capacity, and state of registration. Road tax is payable annually or for the vehicle's lifetime depending on your state's rules.
Q: Is GST included in the road tax for new cars in India?
No — GST and road tax are separate charges. GST is a central tax charged by the vehicle manufacturer at the time of purchase. State road tax is a separate annual or one-time charge levied by your state's transport department. Both apply at the time of first registration, and annual road tax continues for subsequent years.
Q: Do electric vehicles get tax benefits in India 2026?
Yes — electric vehicles in India qualify for a reduced GST rate of 5% (down from 28% for petrol cars). Under FAME-III subsidies, EVs may also qualify for additional state-level incentives, reduced road tax, and free registration in many states. The exact benefits vary by state.
Q: What happens if I don't pay my car road tax on time?
If you don't pay road tax, your vehicle's registration can be flagged in the Vahan database, preventing renewal of fitness certificates and creating legal liability during police checks. Penalties range from Rs200-500 per day of default in most states. Road tax is a legal requirement under the Motor Vehicles Act.
