On going through the query and reply given by our experts, it can be said that the matter is not litigation free if ITC is availed.
However, before applying Section 16(4) we need to pass through Section 16(2) of the Act, whereby, it states that one cannot take ITC unless tax is paid, in case of RCM, tax is to be paid by recipient, as if he is the supplier, merely paying the value of the goods or service will not qualify for ITC (refer 3rd proviso to Section 16(2). In erstwhile Service tax, CENVAT can be taken, in case of RCM, when tax is paid.
Further, GSTR-3B is not the return under Section 39 (as held by High Court), and till date GSTR-2 and GSTR-3 are in abeyance.
Therefore, in view of above, I am of the view that if the amount is considerable, take ITC and prepare for litigation and if amount is bearable book as loss.
Thanks
