The Relevant portion of Section 17(5) is reproduced below as under:
(5) Notwithstanding anything contained in sub-section (1) of section 16 and subsection (1) of section 18, input tax credit shall not be available in respect of the following, namely:-
(a) motor vehicles and other conveyances except when they are used––
(i) for making the following taxable supplies, namely:-
(A) further supply of such vehicles or conveyances ; or
(B) transportation of passengers; or
(C) imparting training on driving, flying, navigating such vehicles or conveyances;
(ii) for transportation of goods;
If we go through the starting line of it says that notwithstanding anything contained in Sub-section 1 of Section 16.......
input tax credit shall not be allowed in respect of the following......
Section 16(1) speaks about availability of input tax credit on goods or services or both used for furtherance of business. Section 17(5) starts with the word notwithstanding anything contained in subsection (1) of Section 16, which means that irrespective anything contained in Subsection 1 of Section 16, input tax credit shall not be allowed in respect of motor vehicles, these input tax credit may be towards purchase of motor vehicle or any service rendered in respect of such motor vehicles.
As such, Shri Kasturiji's opinion is very much correct to the extent that input tax credit on repair and maintenance of motor vehicle is not allowed.
