There are only four cases where ITC on motor vehicles are allowed under GST. The four cases are as follows: Dealer of motor vehicles: If you are a trader of a motor vehicle, then ITC on cars purchased shall be allowed. Transportation of passengers:  If you are a travel agent or a taxi driver and providing services of transportation to the passengers, then the ITC shall be allowed to set off.  Driving schools:  If you are imparting training on driving, flying, navigating such vehicles or conveyance, then ITC shall be allowed on motor vehicles. The vehicle used for transportation of Goods: If you are using motor vehicles to transport your goods from one place to another, then the credit of GST shall be allowed. However, here we are not talking about the Goods Transport Agency (GTA).

if the vehicle is exclusively for carrying goods, then you can take full ITC.
In your case you are using both for business use and personal use. So it is better to not take ITC.
