The threshold limit of exemption of service tax is Rs10 Lakhs. Registration is mandatory after Rs.9 Lakhs. Once the threshold limit is crossed in a financial year the ST has to be paid on the excess over Rs.10 lakhs i.e. in your case on Rs.65,451/-.
Also please note that once the threshold limit is crossed in a financial year in the subsequent financial year all transactions are taxable and the threshold exemption cannot be availed again.
