GST audit threshold — Who needs GSTR-9C in FY 2026-27

GST audit threshold — Who needs GSTR-9C in FY 2026-27

Introduction

Annual GST compliance is an important responsibility for registered taxpayers in India. Apart from periodic GST returns such as GSTR-1 and GSTR-3B, certain taxpayers are also required to file annual returns and reconciliation statements.

One such important compliance is Form GSTR-9C, which serves as a reconciliation statement between the taxpayer's GST returns and audited financial statements. Although the mandatory GST audit by a Chartered Accountant has been removed, eligible taxpayers are still required to file GSTR-9C on a self-certified basis.

This article explains the applicability, turnover threshold, filing requirements, and key compliance considerations relating to GSTR-9C for FY 2026-27.


What is GSTR-9C?

GSTR-9C is a reconciliation statement that reconciles:

  • Turnover reported in GST returns;
  • Tax paid under GST;
  • Input Tax Credit (ITC) claimed; and
  • Figures reported in the financial statements.

The objective is to identify discrepancies between GST filings and books of accounts.


What is the GST Audit?

Originally, taxpayers crossing a specified turnover threshold were required to undergo a GST audit conducted by a Chartered Accountant or Cost Accountant.

However, the requirement for certification by an external professional has been removed. Taxpayers now file GSTR-9C on a self-certification basis where applicable.


Who is Required to File GSTR-9C in FY 2026-27?

A registered person whose aggregate turnover exceeds ₹5 crore during the financial year is generally required to file:

GSTR-9 (Annual Return)

and

GSTR-9C (Reconciliation Statement)

for the relevant financial year.


Understanding Aggregate Turnover

Aggregate turnover includes:

  • Taxable supplies
  • Exempt supplies
  • Exports
  • Inter-state supplies
  • Supplies made on behalf of principals

It is computed on an all-India PAN basis and excludes GST components such as CGST, SGST, IGST, and Compensation Cess.

Taxpayers should always verify the latest notifications and circulars issued by the Government before filing.


Is Chartered Accountant Certification Required?

No

The requirement for certification by a Chartered Accountant or Cost Accountant has been removed.

Currently:

GSTR-9C is filed on a Self-Certified Basis

The responsibility for accuracy remains with the taxpayer.


Information Reported in GSTR-9C

The reconciliation statement includes:

Turnover Reconciliation

Comparison between:

  • Financial statements
  • GST returns

Tax Liability Reconciliation

Verification of:

  • Output tax payable
  • Tax paid through GST returns

Input Tax Credit Reconciliation

Comparison of:

  • ITC claimed in GST returns
  • ITC recorded in books

Additional Liability

Any additional tax liability identified during reconciliation must be reported and discharged.


Common Reasons for Differences in GSTR-9C

Revenue Recognition Differences

Accounting standards and GST provisions may recognize revenue differently.

Credit Notes Issued After Year-End

Timing differences often create turnover mismatches.

Unrecorded Adjustments

Year-end accounting entries may not be reflected in GST returns.

ITC Reconciliation Issues

Differences between books and GST returns are common due to:

  • Vendor non-compliance
  • Reversals
  • Ineligible credits

Due Date for Filing GSTR-9C

GSTR-9C is generally filed along with GSTR-9.

The due date is typically:

31st December following the end of the relevant financial year

unless extended through notification.

For FY 2026-27, taxpayers should monitor official notifications for any extension.


Consequences of Non-Filing

Failure to file GSTR-9C where applicable may result in:

  • GST notices
  • Scrutiny proceedings
  • Demand for reconciliation explanations
  • Additional tax liability
  • Interest and penalties under applicable GST provisions

Practical Checklist Before Filing GSTR-9C

✔ Reconcile turnover as per books and GST returns.

✔ Match GSTR-1 with GSTR-3B.

✔ Verify annual sales figures.

✔ Reconcile Input Tax Credit.

✔ Verify GST payable and GST paid.

✔ Review debit notes and credit notes.

✔ Identify and rectify reporting errors.

✔ Ensure consistency with audited financial statements.


Common Mistakes Made by Taxpayers

Ignoring PAN-Level Turnover

Aggregate turnover must be calculated across all GST registrations under the same PAN.

Mismatch Between GSTR-1 and GSTR-3B

These differences often lead to notices.

Incorrect ITC Reporting

Failure to reconcile ITC may result in tax demands.

Waiting Until Year-End

Periodic reconciliations throughout the year significantly reduce compliance risks.


Benefits of Timely GSTR-9C Filing

  • Improved GST compliance
  • Reduced litigation risk
  • Early identification of discrepancies
  • Better financial reporting accuracy
  • Lower chances of departmental scrutiny

Conclusion

GSTR-9C remains an important annual GST compliance requirement for taxpayers whose aggregate turnover exceeds ₹5 crore during FY 2026-27. Although the mandatory GST audit certification has been removed, taxpayers are still responsible for filing an accurate self-certified reconciliation statement. Timely reconciliation of turnover, tax liability, and Input Tax Credit can help businesses avoid notices, penalties, and future litigation while ensuring complete GST compliance.
