Sir one of my client has registered under service tax in April 2015 and he has received rent from commercial property ₹ 20.00 Lakhs and he has started paying service tax after Crossing ₹ 10.00 Lakhs only on the assumption that, the first 10.00 lakhs is not liable for tax and he has not charged from the client too. is that correct? can u give any notifications for the same!
