Under the constitution the States have the exclusive power to tax sales and purchases of goods other than newspapers
There are however defects of sales tax
It is regressive in nature. Families with low income a larger proportion of their income as sales tax.
Has a cascading effect – tax is collected at all stages and every time a commodity is bought or sold
Sales tax is easily evaded by the consumers by not asking for receipts.
VAT is the tax on the value added to goods in the process of production and distribution.
With the implementation of VAT, the origin based Central Sales Tax is phased out.
Introduced from April 1, 2005
Advantages
Is a neutral tax. Does not have a distortionary effect
Imposed on a large number of firms instead of at the final stage
Easier to enforce as tax paid by one firm is reported as a deduction by a subsequent firm
Difficult to evade as collection is done at different stages
Incentive to produce and invest more as producer goods can be easily excluded under VAT
Encourages exports since VAT is identifiable and fully rebated on exports
Difficulties in implementing
For collection of VAT all producers, distributers, traders and everyone in the chain of production should keep proper account of all their transactions
