The structure of claiming input tax credit is linked to having proof of taxes paid at an earlier stage in the value chain, this creates interlocking incentives for compliance between vendor and customer. No more questions from a vendor: “Would you like that with receipt or without receipt?” Because of this inherent incentive, the total taxes paid, and hence collected, may go up significantly. This provides buoyancy to the GST. In fact, a significant part of the black economy will enter the tax-paid economy.
