GST Expense Breakup in Tax Audit Report

The launch of the Goods and Services Tax (GST) in India substantially reformed the indirect taxation system by merging a host of central and state levies. But the inclusion of GST in accounting and audit procedures has also brought intricacies in financial reporting and compliance, mainly in the context of tax audits. One such sector is the GST expense breakup in the Tax Audit Report under Form 3CD as mandated by the Income Tax Act, 1961.

This article is intended to present a detailed explanation of the GST expense breakup in the Tax Audit Report, its legal foundation, reporting format, taxpayer implications, and best practices for proper reporting.

Background: Tax Audit and Form 3CD

What is a Tax Audit?

A tax audit under Section 44AB of the Income Tax Act, 1961 is a statutory audit conducted by a Chartered Accountant for certain taxpayers to ensure accuracy in the maintenance of books of accounts and to verify the correctness of the income reported to the tax authorities.

What is Form 3CD?

Form 3CD is a comprehensive statement of details to be provided under Section 44AB.

It is an annexure to the principal audit report (Form 3CA or 3CB).

The form has 41 clauses under different heads of financial information like loans, depreciation, payments, deductions, and statutory compliance.

GST-Related Reporting in Form 3CD

With the roll-out of GST on 1st July 2017, various amendments were introduced to Form 3CD to include the reporting of GST-related information. Interestingly, Clause 44 and Clause 16 relate to indirect tax disclosures, including GST.

Let’s explore these two clauses:

Clause 44 – Breakup of Total Expenditure with GST Details

Clause 44 requires breakdown of overall expense on the availability of Input Tax Credit (ITC) as well as type of registration under GST.

This clause assists the revenue authorities in identifying whether companies are utilizing ITC correctly and adopting uniform records while filing GST returns and Income Tax returns.

Purpose of Clause 44:

To provide for a clear look-through of expense vis-à-vis GST compliance

To enable data matching between tax audit reports and GST returns

To identify non-compliance or misuse related to ITC claims

Clause 16 – Amounts Not Deductible under Section 40(a)

This clause encompasses expenses disallowed under the Income Tax Act because of non-compliance with other tax legislation, such as non-payment of GST.

For instance, some costs on which GST is liable under a reverse charge mechanism (RCM) but not paid are disallowed under Section 40(a)(iib) or 43B, as the case may be.

Types of Expenses for GST Expense Breakup

In order to provide correct data under Clause 44, companies must categorize their expenses accurately. The following are typical types and their correspondence with Clause 44:

1. Direct Costs (e.g., Purchases, Charges for Job Work)‍

If ITC is utilized: → Column (i)

If ITC is not utilized → Column (ii)

If bought from a non-registered supplier → Column (iv)

2. Indirect Expenses (e.g., Rent, Legal Charges, Consultancy)

ITC eligible and utilized → Column (i)

ITC not utilized (because of exempt use of service, blocked credits) → Column (ii)

Items such as interest on loans → Column (iii)

3. Salary and Wages‍

Not covered under GST → Generally excluded.

But in case the supply of manpower is contracted,d → Report under respective columns

4. Capital Expenditure‍

Though not in P&L, significant if ITC is taken on assets (such as machinery)

Practical Reporting Challenges

A. Volume of Data: If the company has thousands of transactions, it would be a monumental task to collect the required data in the mandated format.

B. Classification Confusion: There may be uncertainty in establishing whether ITC is utilized or not, particularly when GST is blocked under Section 17(5) of the CGST Act (such as for motor vehicles, club memberships, etc.).

C. Multiple Tax Regimes in the Year: During the transition years (such as FY 2017–18), companies needed to bifurcate data between pre-GST and post-GST periods.

D. Differences Between Books and Returns: Expenses in books may not necessarily match GSTR-2B, resulting in reconciliation problems.

Steps to Prepare GST Expense Breakup for Tax Audit

Step 1: Extract Trial Balance and Ledger Data
Export all expense ledgers from your accounting software, e.g., purchases, services, and operational expenses.

Step 2: Identify GST Registration Status of Vendors
Classify vendors into:

Registered under GST

Not registered under GST
Use vendor master records and GSTIN validation tool for this purpose.

Step 3: Tag ITC Status
Tag each expense entry on the basis of:

Whether ITC was availed

Whether ITC was not utilized (and why)

Whether the item is exempt or non-GST supply

Step 4: Fill Clause 44 Table

Fill totals as per classification:

Total expenditure

Expenses attributable to registered suppliers (with/without ITC)

Expenses attributable to unregistered suppliers

Exempted supplies
Make sure that the total column-wise amounts tally with the trial balance totals.

Step 5: Reconcile with GST Returns
Make sure the expenses where ITC is claimed tally with GSTR-3B and GSTR-2B data to prevent audit discrepancies.

Example of GST Expense Breakup

Sl. No.	Total Expenditure	(i) ITC Availed	(ii) ITC Not Availed	(iii) Exempt Supplies	(iv) Unregistered Entities	(v) Total to Registered	(vi) Total to Unregistered
1	₹1,00,00,000	₹30,00,000	₹20,00,000	₹10,00,000	₹5,00,000	₹60,00,000	₹40,00,000

Note:
The sum of (i) to (iv) should be equal to the total expenditure.
(v) and (vi) are for reference and cross-checking.

Implications of Incorrect Reporting

Incorrect GST breakup can result in:

Tax notices and scrutiny

Disallowance of ITC

Penalties under GST and Income Tax Acts

Delays in audits and return processing

In addition, inconsistencies may be highlighted by data analytics solutions employed by tax functions.

Best Practices and Recommendations

For Taxpayers:

Update vendor GSTIN database

Use accounting software that has GST classification support

Use custom scripts or tools to automatically generate reports

Reconcile books and ITC claims against returns monthly

For Auditors:

Verify GST data with GSTR-2B and 3B returns

Obtain management representations in doubtful cases.

Report limitations or qualifications in the audit report if data is missing.

Maintain documentation and working papers for Clause 44

To the Government:

Clarify treatment of capital expenditure under Clause 44

Grant relaxation in reporting norms for small taxpayers

Facilitate system-based reconciliation tools for tax auditors

Recent Developments and Relaxations

Clause 44 has been postponed several times since its inception, owing to difficulties in its implementation.

Despite this, it became obligatory from AY 2022–23 onwards.

The CBDT has released FAQs and clarifications to facilitate taxpayers in meeting the requirements of Clause 44.

Conclusion

The GST expense segmentation in the Tax Audit Report, particularly under Clause 44 of Form 3CD, is an important aspect of blending indirect tax compliance with income tax determination. While this introduces complexity, it also encourages transparency, enhances data analytics for the government, and enforces improved tax discipline on companies.

To ensure effective compliance, businesses need to keep proper records and use technology to classify data automatically and reconcile data. Auditors, on the other hand, need to grasp the subtleties of GST and income tax interplay to create a reasonable and true audit report.

Tax compliance in the future will involve interoperability across varying tax regimes, and Clause 44 is towards that end—it gets India further towards a standardized, digital-priority taxation paradigm.
