Goods & Services Tax Law in India is a comprehensive, multi-stage, destination-based tax that will be levied on every value addition.
In simple words, GST is an indirect tax levied on the supply of goods and services. GST Law has replaced many indirect tax laws that previously existed in India
Before GST, tax on tax was calculated and tax was paid by every purchaser including the final consumer. The taxation on tax is called the Cascading Effect of Taxes.
GST avoids this cascading effect as tax is calculated only on the value add. at each transfer of ownership.
