Service tax query (related to subcontractor)

as per notification 33/2012- ST, Any Service provider whos turnover is not exceeding rs 10,00,000 in the previous year, shall not have to pay service tax. as if your sub contractor is only providing services to you and his turnover being only rs 8,00,000 he need not to get himself registerd under service tax. and you have deducted TDS on Contractos so you are not liable to anywhere. further for any clarification, please let me know.
