- Annual savings: Rs 80,000-1,50,000 for high-usage vehicles
CNG Vehicles: Lower Tax Alternative
CNG offers an intermediate tax advantage:
- Lower fuel price: Rs 75-80/kg
- Better mileage: 20-25 km/kg
- Lower running cost: 30-40% cheaper than petrol
Fuel Tax Impact on Car Selection
| Fuel Type | Tax Burden | Best For |
|---|---|---|
| Petrol | High excise + VAT | Low usage <10,000 km/year |
| Diesel | Lower fuel, higher car tax | High usage >15,000 km/year |

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.

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.

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.
