Thanks for your reply.Is there any valid document where the same is clearly mentioned.
Why I'm asking this is because...
In few cases where we pass on some discount to our client,then they ask us to charge Service tax on after discount amount i.e. Net and not on the Basic/Gross amount.
In that particular time we do not have document to defend our point.
So,I would like to request you that if there is any document supporting to the particular point,please let me know.
