Further, Rs 10,145 crores is being transferred to CGST account from IGST account for the month of November 2017 by way of settlement. The major reason for the gap in income of CGST and SGST (State GST) has been that more CGST liability has been discharged using transition credit rather than by way of cash. Thus, taxpayers are using the balance credit available with them in the previous tax regime, which is the reason why there is an additional revenue gap in the centre's revenue.
The reason for downward trend of tax revenue under GST could be attributed to the following factors :
- Because of the first time requirement of paying IGST on transfer of goods from one state to another state even within the same company, there was an additional cash flow of IGST in the first 3 months. As and when the final transaction of these goods takes place, the credit for IGST is being utilized for payment of SGST and CGST and therefore, the inflow of new taxes is low
- Since the overall incidence of taxes on most of the commodities have come down under GST, it would naturally have some implication on the revenues of the government.
- The tax administration of GST is now based on self-declared tax return, in which the assessee decides on his own how much tax liability he has and claims input tax credit as per his own calculations. Since implementation of some of the main features of GST such as, matching of returns, e-way bill as well as reverse charge mechanism have been postponed the tax compliance may not be up to the mark.
