I am a Small service provider(service<1000000). However i have wrongly raised invoices for few services and paid the S.T . Now the Service tax dept is demanding service tax on whole of the Service amount. Is there any seperate provision/case laws through which i can take a stand that i'm a SSP and S.T liability demanded need not be paid??What is the solution ??
