We follow the following GST audit procedures and GST audit checklists to carry out the audit:


Our auditors study the effectiveness of internal controls and internal checks established by the management to ensure GST compliance. A review of internal controls applicable to transactions like sales returns, sale on approval basis, and job work is also carried out for their completeness and actual implementation. Our GST auditors also study the adequacy of records maintained under GST and provide their recommendations.


Our GST Auditors verify the GST registration certificate, classification of supplies and services under GST, reverse charge, purchase register, sales register, stock register, expense ledgers, monthly and quarterly returns, and other records maintained by the company as per the requirements of the law.


We cross-check GSTR-3B with GSTR-1 and 2A to ensure that input tax credit has been properly claimed. We also check the arithmetical accuracy of figures and identify mismatch, if any. Based on our findings, we recommend management to make necessary changes.


We check the Sales invoices to ensure that the format of the invoice complies with the law. We then go on to check the arithmetical accuracy of the same and check if the tax rate is correctly charged considering the goods and services supplied.

We also check purchase invoices for their eligibility for input tax credit (ITC) and verify if the total of such ITC matches with the amount of credit claimed in the GST return.


Our GST auditors check if the input tax credit is reversed if the invoice under review has remained unpaid for more than 180 days.


We check if the e-way bill is generated for each supply having value more than Rs. 50,000 and supplies made via motorised vehicles. They also check if the e-way bill matches the invoice.
