In its first review of the performance of the goods and services tax (GST), the Comptroller and Auditor General (CAG) on Tuesday pointed to several gaps in the new regime and said even after two years, system-validated input tax credit (ITC) through "invoice matching" was not in place and a non-intrusive e-tax system remained elusive. "The complexity of the return mechanism and the technical glitches resulted in rollback of invoice-matching, rendering the system prone to ITC frauds. Without invoice-matching and auto generation of refunds, assessments, etc on the whole, the envisaged GST tax compliance system is non-functional," the CAG said. The audit pointed out the vulnerability of the system to fraudulent ITC claims. It found the system allowed unrealistic and erroneous claim of ITC of IGST by one taxpayer, representing 79% of total ITC claim by all taxpayers for a month, thus exposing the vulnerability of the system to fraudulent ITC claims.
"The system of payment and settlement of tax that was envisaged for GST was based on 100% invoice-matching and availment of input tax credit, as well as settlement of IGST on the basis of invoice matching. Neither is possible as of now, as an invoice matching system has not kicked in," the CAG said. This is the first audit report of CAG on GST based on review of the system for the financial year 2018 19. The auditor said the extent of changes, having to be now undertaken, as well as the suspension of key aspects of the system, pointed to inadequate coordination among the stakeholders such as department of revenue, Central Board of Indirect Taxes and Customs (CBIC) and GSTN as well as failure to try out the system adequately before rollout.
