Under notification 15/2012 of the Service Tax, the burden of service tax is both upon service provider and receiver in the ratios mentioned for some services.
Whether it is mandatory to share the burden in the ratio specified or can the service provider bill service tax at full rate on the service reciever so that the service receiver only has to pay the service tax amount to the provider. The service tax collected will be deposited by the provider to the government. The service receiver need not bother about depositing his share of service tax to the government, once he has paid it to the service receiver.
