1.If his turnover exceeds Rs. 40 lakhs he needs to register. Since he is buying the cars he will register as a trader.
2. I dont think so because for second hand vehicle dealer government has announced that they need to pay tax on margin, however turnover would be the sale price and if one goes under composition scheme then he/she will have to pay tax on output supply and not margin.
3.It shall be the rate depending on the vehicle which can range from 12-28%.
4. It will depend on the engine.
5. Yes on any services which is not mentioned else where GST rate would be 18%.
Hope you find the information helpful if you do please rate it 5 and provide your valuable feedback for my improvement.
Thank you.
