I have received suggestions to prepare an article on ‘Audit conduct by the GST Department’ under Section 65 of CGST Act,2017.   I have covered the following topics on Audit conducted by GST officer under Section 65 of CGST Act,2017 for your easy reference and prepare records to be submitted to the GST audit officer to complete your client’s audit  smoothly and to complete within prescribed time limit as per CGST Act,2017.

Dear colleagues, we have completed 4 years of GST Law. The honorable Union Finance Minister made a proposal of “scrap GST Audit” in Union Budget,2021.  The scope of GST Audit under Section 65 has been increased.  As per information from the reliable source from the CGST Department “MASSIVE CASES” will be taken in GST Audit as per Section 65 of CGST Act, 2017. So, it’s time to know “how to select cases for Audit under Sec.65 and what are the Risk Parameters for selection of Audit” by the CGST Department. So, I thought in my mind to create certain awareness and to provide certain important key points on GST Audit taken by the GST Officers under Section 65 of CGST Act,2017 with relevant notifications, Press Releases and Instructions  issued by the CBIC from time to time to prepare data for completion of audit  and discuss with the GST Audit Officer by all the GST professionals on various doubts arising by the GST Audit officer  during the GST Audit to the tax professionals.

Audit conducted by GST department under Section 65 of CGST Act, 2017

As per Section 65(1) of the CGST Act, 2017, the Commissioner or any officer authorized by him, by way of a general or a specific order, may undertake audit of any registered person for such period, at such frequency and in such manner as may be prescribed. The period of audit to be conducted under Sub-section (1) of Section 65 shall be a financial year or multiplies thereof as per Rule 10(1) of CGST Act, 2017.

As per Section 2(13) of the CGST Act, 2017, ‘Audit’ means the examination of records, returns and other relevant documents prescribed in the CGST Act,2017, whether the tax payer has maintained or furnished by the registered person under this Act or the rules made thereunder to verify correctness of turnover declared and taxes paid there on, input tax claimed by the tax payer and followed compliance with the provisions of the CGST Law.

Now Friends, let us understand “what are the Rick Parameters” for Selection of audit cases by the GST Department.

Some of the important Risk Parameters that could be considered during selection of audit by Audit Commissioner are as under:-

What are the consequences if not responded to the notices by the taxpayer?

The   taxpayer should respond promptly to the notice issued in his /her name within the time specified . In case, the taxpayer fails to do so, he will be legally acted upon. The GST authorities can eventually prosecute such a taxpayer or consider it as a purposeful default and charge the taxpayer with penalty. But, as a good practice and timely reply to the notices, Taxpayers are always advised to keep track of information reported on GST Portal.

If any irregularity or mistake is observed, taxpayer should try to correct the same in the most latest return, if possible, also, taxpayer should reconcile all the returns with each other, like turnover reported in Form GSTR-1 with Form GSTR-3B and E-Way Bills generated and also reconciliation of Input Tax Credit availed in Form GSTR3B with Form GSTR-2A or Form GSTR-2B.

How to identify differences between Form GSTR-2A and Form GSTR-3B ?

Generally these following differences happen between Form GSTR-2A and Form GSTR-3B.

[i] The supplier is having frequency of uploading Form GSTR-1 Quarterly,

[ii] Input Tax Credit as per Reverse Charge Mechanism,

[iii] Input Tax Credit relating to Import of Services and Goods,

[iv] The important issues is Supplier has not uploaded and filed Form GSTR-1 in time and not properly filed and uploaded.

[v] The buyer has not made payment on inward supply of goods and services within specified time i.e. within 180 days , but supplier raised invoice as per GST law at the time of supply of goods and services but recipient has claimed ITC on such invoices. So, under these circumstances buyer has reversed ITC along with interest and informed supplier.

If the buyer has identified differences between Form GSTR-1 and Form GSTR-3B , how to rectify such differences by the buyer?

If the buyer has identified any differences between Form GSTR-1 and Form GSTR-3B, he has to take appropriate steps i.e. to follow up supplier and inform to upload Form GSTR-1 timely with correct details of Tax invoices with correct tax and value of supply of gods and services.

What is the importance to reconcile Form GSTR-1 with Form GSTR-3B by the taxpayer?

The GST department is watching taxpayers’ data along with Form GSTR-1 and Form GSTR-3B regularly with their data analysis wing  as per GST audit manual issued by the GST department from time to time to select files for GST audit by the GST authority as per Section 65 of CGST Act. If GST analysis identifies difference as per GST manual GST audit department issues notice on Form ASMT-10 to the tax payer to submit all the records for audit under Section 65 of the CGST Act.

What are the consequences, if any mistakes are identified by the GST Audit officer?

During the audit due to many reasons mistakes are made by the taxpayer like:-

[i] Wrong or Fake invoices are issued by the taxpayer,

[ii] False information provided while registering under GST or financial records or documents or has filed fake returns to evade tax and has hidden information or has given false information during proceedings,

[iii] The taxpayer has collected GST but did not submit it to the GST department within 3 months,

[iv] The taxpayer has taken ITC without actual receipt of goods and services,

[v] If the taxpayer deliberately suppressed outward supply of goods or services to evade tax and other mistakes, the taxpayers are liable to pay penalty as per below:-

S.No. Types of mistakes Liable to pay penalty

3 Maximum penalty may be — The amount of penalty may extend to Rs.25,000/-
