If the turnover exceeds Rs. 10 Lacs definitely service tax is applicable.
Further, you have mentioned that you have obtained service tax number. At the time of applying for service tax number you are giving a declaration that you will be paying service tax even if turnover is below taxable limit.
So in any case, you have to pay service tax and file service tax return.
In case, you have not done it before you can apply and pay under amnesty scheme.
