Dear Krishna Murthy Ji,
Answer in short is ₹ 9 lakhs. The person will apply for registration as and when its turnover exceeds 9 lakhs and not avail the benefit (threshold exemption) of ₹ 30 lakhs.The amount of abatement will not be deducted in determining the aggregate value.
You have intermingled the concept of 'abatement' and 'threshold exemption limit' for small scale service providers.Both are not correlated at all.
1. The question of availing abatement from the gross receipt arises only after getting registration of Service Tax. It is very much clear and not deniable. A person who is not registered with ST department by virtue of the whole exemption or value based exemption cannot avail abatement, that person being unregistered.
2. For registration purpose one will apply for ST registration certificate after crossing ₹ 9 lakhs.
3. As per notification No. 33/12-ST dated 20.6.12 as amended, if ST on freight is paid by service receiver under RCM, that value will be excluded from the aggregate turnover to arrive at threshold exemption limit of ₹ 10 lakhs. See para no.3 of the notification.
An illustration :
Suppose P & L Account of GTA shows the following gross receipts in the preceding year:-
(A ) Amount received for which ST is payable by the consignor or consignee : ₹ 30 Lakhs
(B) Amount received for which ST is payable by GTA : ₹ 8 lakhs
Total ₹ 38 Lakhs
Only ₹ 8 lakhs will be considered and the GTA shall be eligible for small service (scale) provider exemption.
Note : It is again mentioned that the amount of abatement will not be deducted in determining the aggregate value.
