I've started a Manpower Supplier consultancy primarily for the informal labour market. I need to know whether I should quote ST from my clients. In that case, service tax registration is compulsory. But, what if my annual revenues doesn't cross Rs 10 lacs ? What about the service tax that has been collected from various clients ? Please guide me
