I have bought a new car. Shall I take claim GST amount in one time?
You can not claim Gst. this is consumer based transaction. if a vehicle is purchased for only factory use and used only in factory premise then only its Gst can be claimed as ITC.
If the Car brought is used in the furtherance of business you can avail the ITC. With respect to whether to take the credit in a single year, yes you can take the credit in a single year. No need to split in two years like in previous law.
