GST Audit Limit: A Guide for Taxpayers with Annual Turnover Above 2 Crores

Following the Finance Act of 2021, the mandate for GST (Goods and Services Tax) audit and the submission of GSTR-9C certified by CA/CMA (Chartered Accountant/
Cost and Management Accountant) was abolished. During the 43rd GST Council meeting on 28th May 2021, it was advised that taxpayers with an annual aggregate turnover of ₹5 crore or more may still submit GSTR-9C, but as a self-certified document. The CBIC (Central Board of Indirect Taxes and Customs) officially communicated this update in Notification No. 29/2021 – Central Tax, dated 30th July 2021.

Understanding the GST Audit Limit and Its Importance

An audit under GST means scrutinising records, returns, and documents maintained by someone registered under GST. This process verifies the accuracy of declared turnover, taxes paid, refunds claimed, and input tax credit utilised and ensures compliance with the GST Act by an authorised expert.Since GST operates on a trust-based system, taxpayers must self-assess their tax obligations, remit taxes, and file returns accordingly. Therefore, an audit mechanism is crucial to verify that taxpayers have accurately assessed their tax liabilities. The government implements various measures, including audits, to ensure the effective enforcement of the GST framework.

GST Audit Limit: Types of GST Audits

Types of GST Audit Performed By When Initiated
Turnover-based Audit Chartered Accountant or Cost Accountant appointed by the taxpayer As per the CGST (Central Goods and Services Tax) Act, if the Turnover exceeds 2 crore, the taxpayer has to get his accounts & records audited
Normal audit/General Audit Commissioner of CGST/SGST(State Goods and Services Tax) or any officer authorised by him On the order of the commissioner by giving 15 days prior notice
Special audit A Chartered Accountant or Cost Accountant nominated by the commissioner On the order of the Deputy/Assistant Commissioner, with prior approval of the commissioner

GST Audit Limit under Section 35(5) of CGST Act for Turnover-based Audit

If the annual turnover of a registered taxpayer exceeds ₹2 crore in a financial year, he/she must have his/her accounts audited annually by a Chartered Accountant (CA) or Cost Accountant. A financial year extends from April of one calendar year to March of the next. Special Note: For determining the turnover limit for the Financial Year 2017-18, a government press release dated 3rd July 2019 stated that the period will cover from 1st July 2017 to 31st March 2018, not including the first quarter of FY 2017-18. For businesses with an annual turnover under ₹5 crore, the requirement to file GSTR-9C for FY 2018-19 has been waived. Calculation of Aggregate Turnover Aggregate turnover includes the value of all taxable (both inter-state and intra-state) supplies, exempt supplies, and exports of goods and services.The calculation of total turnover is based on the PAN Card. This implies that if the turnover under a PAN exceeds ₹2 crore, all business entities registered under that GST for the PAN must undergo a GST audit for the financial year. Aggregate Turnover = Value of all taxable supplies (inter-state and intra-state) + value of exempt supplies + value of exports of goods and services + value of inter-state supplies of persons having the same PAN details Note: The formula excludes central tax, state tax, union territory tax, integrated tax, and cess.

Understanding GST Audit Limit: Composition of Aggregate Turnover

Items Included in Aggregate Turnover Calculation:

  • All taxable supplies (inter-state and intra-state), excluding those on which reverse charge applies.
  • Supplies made between distinct business verticals.
  • Goods supplied to or received from a job worker on a principal-to-principal basis.
  • Value of all exports or zero-rated supplies.
  • Supplies made by agents or job workers on behalf of a principal.
  • All exempt supplies, such as agricultural produce and branded ready-to-eat food.
  • All taxes, excluding those under GST, like entertainment tax on movie tickets.

Items Excluded from Aggregate Turnover:

  • Inward supplies where tax is paid under reverse charge.
  • All taxes and cess under GST, including CGST, SGST, IGST(Integrated Goods and Services Tax) , and compensation cess.
  • Goods supplied to or received back from a job worker.
  • Transactions are classified as neither goods nor services under Schedule III of the CGST Act.

GST Audit Limit: Qualifications and Eligibility of GST Auditors Eligibility Criteria for GST Auditors: Only a Chartered or a Cost Accountant is authorised to conduct a GST Audit under Section 35. Important Points to Consider:

  • An internal auditor cannot simultaneously serve as a GST Auditor.

As such, a Chartered Accountant involved in the audit must not be registered as a GST practitioner when issuing the Audit Report.
  • For entities with multiple branches registered under GST across various states or UTs(Union Territories), the combined aggregate turnover of all branches is considered when determining the ₹2 crores threshold for GST audit applicability.

Entities may choose to appoint one auditor for all branches or individual
