Dear Sh.Alkesh Jani Ji,
I agree with you to the extent that AAR decision is applicable to the applicant only. It is also to be taken care of the fact that each and every case has different facts, situations and circumstances. One has to be very cautious. I am of the view any AAR clears the doubt and pave the way for going ahead in which direction. Here I am expressing my views and am not comment upon any decision of High Court or any court. Before resorting to Section 8 of CGST Act, 2017 we are supposed to read carefully the definition of Composite Supply and Exempt Supply which are extracted below:
Section 2(30) of CGST Act, 2017 “composite supply” means a supply made by a taxable person to a recipient consisting of two or more taxable supplies of goods or services or both, or any combination thereof, which are naturally bundled and supplied in conjunction with each other in the ordinary course of business, one of which is a principal supply;
Illustration. - Where goods are packed and transported with insurance, the supply of goods, packing materials, transport and insurance is a composite supply and supply of goods is a principal supply;
(47) “exempt supply” means supply of any goods or services or both which attracts nil rate of tax or which may be wholly exempt from tax under section 11, or under section 6 of the Integrated Goods and Services Tax Act, and includes non-taxable supply.
108) “taxable supply” means a supply of goods or services or both which is leviable to tax under this Act;
In view of the above, it can be easily arrived at the conclusion that composite supply consists of two or more taxable supplies and not one taxable and one exempt. Thus exempt supply is excluded from the scope of composite supply. So erection and installation is not ancillary activity. It is independent.
This is my view.
