Sh.Kalpesh Bhatt Ji,
Reply is as under :-
1. Service Tax is payable only on taxable value of ₹ 1.20 lakhs and NOT on the whole amount of ₹ 11.20 lakhs because you are entitled to threshold exemption limit of Rs. Ten lakhs in the year 15-16 also.
Go through relevant clause of Notification No.33/12-ST dated 20.6.12 which is as follows:-
Provided that nothing contained in this notification shall apply to,-
(viii) the aggregate value of taxable services rendered by a provider of taxable service from one or more premises, does not exceed ten lakh rupees in the preceding financial year.
The word, 'preceding' makes it crystal clear that you are entitled to small scale exemption of ₹ 10 lakhs in 15-16. There is not even an iota of doubt about this entitlement.
2. There must be email ID of the SCN issuance authority in the SCN (at the top of SCN). You can email reply to the SCN citing the above clause.The word, 'preceding' should be emphasized.
I suggest that you must read the SCN word for word very carefully. In my view, the department cannot commit such mistake.
Anyhow, if your query is correct, ST is payable only on taxable value of ₹ 1.20 lakh and not on the value of ₹ 11.20 Lakhs.
