India, particularly being a trading community, has always believed in accepting and adopting loopholes in any system administered by State or Centre. If a well-administered system comes in, it will not only close options for traders and businessmen to evade paying their taxes, but also make sure that they’ll be compelled to keep proper records of sales and purchases.
Under the VAT system, no exemptions are given and a tax will be levied at every stage of manufacture of a product. At every stage of value-addition, the tax that is levied on the inputs can be claimed back from tax authorities.
Secondly, under VAT, if the payment of tax is avoided at one stage nothing will be lost if it is picked up at later stage. Even if it is not picked up later, the government will at least have collected the VAT paid at previous stages. Where as if evasion takes place at the final/last stage the state will lose only tax on the value added at that particular point.
