Detailed understanding of the operations:

Scrutiny of financials: Once the operation side is understood, next step is to scrutinise the financials of the company including trial balance, statement of profit or loss and the balance sheet. The financials provide us the better picture of current status of compliance and the possible impact under GST. Related party transactions, major vendor details, major customers, receipts and payment in Forex, profitability, direct and indirect sources of income etc could be identified which would play crucial role in reporting the impact of GST on each of such relevant item.

Impact on Revenue:

  • Supplies without consideration
  • Impact on procurement
  • Impact on Expenditure

Impact on Input tax credits:

It is equally important to analyse the status of input service distributors, conditions, and applicability under GST with change in other provisions relating to registrations and input tax credit.

Impact on Place of supply and Time of Supply
Impact on Valuation

Transitional issues:

Apart from the above, there are many other areas which needs attention like agreement vetting, relevance of warehouses outside state, impact of antiprofiteering clause, FTP benefits, IT/ERP customisation, GST returns etc. The events which is neutral under both regime could be ignored like ineligible credits. Exempted activity under both current tax and GST.


The GST impact study report shall be prepared considering all the possible areas where the attention of management is needed. The scale of impact study would differ from one entity to another depending on its size, volume and nature of operation. In-depth knowledge in subject and clear cut understanding of the client’s business would yield fantastic result in order to provide optimum value addition along with protection from possible threats when the GST is implemented.
