GST is a comprehensive indirect tax levy on manufacture, sale and consumption of goods as well as services at the national level and it will replace all indirect taxes levied on goods and services by the Indian Central and State governments. Today consumers have no idea about the extent of taxes they pay on goods. If we get a bill after buying merchandise which gives the extent of VAT we have paid, it is an understatement of the actual tax we have paid. Therefore, today it is reasonable to assume we pay well over 20% tax for most merchandise we buy. VAT was the highest contributor in tax revenue of state governments. But after the implementation of GST this will now subsumed along with surcharge and cess into GST. As the barriers between states are removed, we as consumers will not end up paying “tax on tax” which is what happens when goods move across state borders. It will now unify all the indirect taxes under an umbrella and will create a smooth national market.
