The following taxes are included in the ex-showroom price of a motor car:
* Goods and Services Tax (GST): GST is a consumption tax levied on the sale of goods and services in India. The GST rate for motor cars is 28%.
* Central Excise Duty (CED): CED is a tax levied on the manufacture of goods in India. The CED rate for motor cars is 12.5%.
* Customs Duty (CD): CD is a tax levied on the import of goods into India. The CD rate for motor cars varies depending on the country of origin.
* State Road Tax: This tax is levied by the state governments in India on the purchase of motor vehicles. The rate of state road tax varies from state to state.
The total tax amount included in the ex-showroom price of a motor car can be calculated as follows:
```
Total tax amount = (Ex-showroom price + CED + CD) * GST rate + State Road Tax
```
For example, let us assume that the ex-showroom price of a motor car is ₹10,00,000. The CED rate is 12.5% and the CD rate is 10%. The GST rate is 28%. The state road tax is 9%.
The total tax amount would be:
```
Total tax amount = (10,00,000 + 125000 + 100000) * 28% + 90000
= 12,25,000 * 28% + 90000
= 3,43,000 + 90000
= ₹4,33,000
```
Therefore, the total tax amount included in the ex-showroom price of the motor car is ₹4,33,000.
