Dear querist,
First and foremost, I think the same query is being repeated by you in multiple posts/ replies but each time the facts given by you are different and contradictory to each other. For example;-
1. tax has been paid on the supply
In your original query, you have mentioned "invoice without supply". Now you the fact being presented by you is "tax has been paid on the supply". This appears to be contradictory.
Therefore, even the fundamental premise of the entire issue in your query is ambiguous, at least to me.
Coming to the issue posed by you, without any specific comments on the facts of your case:
1. Any amount cannot be simply availed purporting it to be Input tax credit unless it falls within the definition under section 2(62)/2(63), confirms to section 16(1), 16(2), 16(3), 16(4), section 17 and the rules thereunder. All these facets has to be verified in the hands of the recipient as burden of proof is on the recipient to prove such claim u/s 155. In this case, there may be various challenges such as:
1. conformity to definition of "input tax"
2. No actual receipt of goods etc
Further, the penalty is levied on two different person here for two different acts/ offences though it may be in the course of same transaction.
Also from the facts, it is not known whether there is any collusion between the supplier and the recipient.
I think in the previous queries raised by you such as issue id 118804 and this particular query, the contributors have given their views in this aspect. As explained by Ld Amit Ji, there are multiple facets involved in this particular issue and without knowing the exact facts of your case, none of the contributors in this forum will be able to give a proper reply to your satisfaction. My humble suggestion to you is to consult an expert by presenting her/him with the full facts of the case including SCN, and get an expert opinion.
