Service tax is an indirect tax levied by the Central Government on services provided in India except Jammu & Kashmir. It aims to broaden the tax base, increase revenue, and encourage citizen participation in the economy. Service tax applies to the value of all taxable services except those specified in the Negative List. To be liable, a service must be provided for consideration in the taxable territory and not be included in the Negative List. The service provider is responsible for remitting and collecting the tax, though in some cases the recipient or both parties are liable. Sources of service tax law include the Finance Act and section 65B definitions.
