Form 3CD Reporting for AY 2026-27: Clause-Wise Changes Every Business Should Check Before the Tax Audit

TL;DR Summary: Form 3CD is the statement of particulars filed with your tax audit report under Section 44AB. It has 44 clauses split into Part A (basic details) and Part B (financial particulars). It always goes with Form 3CA or Form 3CB, never alone. Clauses 21, 26, 34 and 44 draw the most scrutiny from the tax department. Clause 44 asks for a GST-wise break-up of your expenses. Numbers in Form 3CD should match your GST returns and your ITR. Mismatches between these three documents are a common trigger for notices. Your auditor prepares the form, but you own the underlying data. Form 3CD still applies for FY 2025-26 (AY 2026-27). A new unified Form 26 takes over from Tax Year 2026-27.

Form 3CD is the 44-clause statement of particulars filed under Section 44AB alongside Form 3CA or 3CB during a tax audit. For AY 2026-27, clauses 21, 26, 34, and 44 draw the most scrutiny, and Clause 44’s GST-wise expenditure break-up must reconcile precisely with your GSTR filings and ITR.

If your business crosses the tax audit threshold in India, form 3cd becomes part of your annual routine, whether you run a trading firm, a manufacturing unit or a professional practice. 

It is the detailed statement your chartered accountant attaches to the tax audit report and it decides how closely the department looks at your books.

This blog explains what Form 3CD covers, how it connects with Form 3CA and 3CB, which clauses cause the most trouble and how to keep your GST filings and ITR in sync with it.

What is Form 3CD and Who Prepares It

Form 3CD is the backbone of the tax audit process in India. It is a statement of particulars prescribed under Rule 6G(2) of the Income-tax Rules, 1962, that must be furnished along with the tax audit report under Section 44AB. 

The form is mandatory for taxpayers who cross the prescribed turnover or gross receipts thresholds for their business or profession.

The preparation of Form 3CD is the responsibility of a Chartered Accountant (CA) in practice who conducts the tax audit. 

However, the information contained in the form comes from your books of account and other records. The auditor examines your financial statements and supporting documents to ensure the particulars reported are true and correct.

Who Needs a Tax Audit?

The rule is set out under Section 44AB and the numbers have stayed steady for a while:

Category	Threshold	Digital transaction relief
Business	Turnover above Rs 1 crore	Rs 10 crore if at least 95% of receipts and payments are digital
Profession	Gross receipts above Rs 50 lakh	No relief threshold
Presumptive scheme opt-out	Income claimed lower than presumptive limit	Applies under Sections 44AD, 44ADA, 44AE

The tax audit report must be filed electronically on the income-tax e-filing portal by 30 September of the assessment year (AY).

Important Update for AY 2026-27

From Tax Year 2026-27 (AY 2027-28), Form 3CD will be replaced by the new Form 26 under the Income-tax Act, 2025. 

The new form expands reporting requirements from 44 to 55 clauses and introduces new disclosures including details of cloud storage used for books of account and the location (IP address and country) where backup servers are located. 

However, for AY 2026-27, the current Form 3CD with its amendments remains applicable.

Taxpayer’s Role in the Process

While the tax auditor prepares and signs Form 3CD, you are responsible for maintaining proper books of account and providing accurate information. 

The auditor will rely on the records and explanations you provide. If you fail to maintain adequate records or provide incomplete information, the auditor must qualify the report, which can trigger departmental scrutiny.

Form 3CA/3CB vs. 3CD: How the Three Forms Fit Together

As a taxpayer, you must understand the relationship between Form 3CA, 3CB and 3CD. These three forms work together as a single audit package, but each serves a distinct purpose.

Form 3CA: When Another Law Already Audits Your Books

Form 3CA is the audit report format used when your books of account are already required to be audited under another law. 

For example, companies audited under the Companies Act, 2013, or LLPs audited under the LLP Act, 2008, use Form 3CA. 

The tax auditor essentially relies on the statutory audit already conducted and provides additional information relevant for income-tax assessment.

Form 3CB: When No Other Law Requires An Audit

Form 3CB is used when your business or profession is not required to get its accounts audited under any other law. 

This usually applies to partnership firms, proprietary concerns, and individual professionals who are not covered by any other audit requirement. 

The tax auditor conducts a full audit specifically for income-tax purposes and expresses an opinion on whether the financial statements give a true and fair view.

Form 3CD: The Common Annexure

Regardless of whether you use Form 3CA or 3CB, Form 3CD is always attached as an annexure. It is the statement of particulars that contains all the detailed disclosures required under Section 44AB.

Form	Who Uses It	What It Certifies
Form 3CA	Companies and entities already audited under another law	That the tax audit has been conducted, with Form 3CD attached
Form 3CB	Proprietorships, firms, LLPs not audited elsewhere	True and fair view of accounts, plus the tax audit opinion
Form 3CD	All of the above	The 44-clause statement of particulars

The difference is important when you are filing. On the income tax e-filing portal, you will see the combined utility as either Form 3CA-3CD or Form 3CB-3CD, never Form 3CD by itself. 

Form No. 3CA/3CB is a format of audit report, whereas Form 3CD is a statement of particulars required to be furnished under Section 44AB of the Income-tax Act. 

Your CA picks the correct combination based on whether a statutory audit under another law already exists for your entity. A mistake at this stage, filing 3CA-3CD when 3CB-3CD was needed, or the other way round, gets flagged during processing and can delay your return. 

It is a small procedural point, but it is the first thing your auditor should confirm before the actual clause-wise work begins.

Important Note for AY 2026-27

Starting Tax Year 2026-27, Forms 3CA, 3CB, and 3CD will be consolidated into a single Form 26 under the new Income-tax Act, 2025. This consolidation aims to simplify tax compliance and standardise reporting formats

Clauses That Cause the Most Scrutiny: 21, 26, 34 and 44

Not all 44 clauses carry equal weight during assessment. Some of them deal with disallowances, cash flow tests and cross-checks against other tax filings and these are the ones assessing officers tend to examine first.

Clause 21: Disallowable Expenses

This clause requires reporting of amounts debited to the profit and loss account that are inadmissible under various provisions. Common issues include:

• Expenses where TDS was not deducted or was short-deducted
• Cash payments exceeding ₹10,000 in a single day
• Interest, salary, bonus, or commission paid to partners that exceeds the limits under Section 40(b)
• Personal expenses charged to the business
• New for AY 2026-27: Settlement expenses that are not actually paid

The tax department reviews this clause to identify expenses claimed as deductions that should be disallowed. If your auditor reports significant disallowable amounts, you can expect related questions.

Clause 26: Section 43B Compliance

This clause deals with statutory dues that are allowable only on actual payment. It covers:

• Employees’ contributions to PF, ESI, and other funds
• GST, excise duty, and customs duty
• Tax collected at source

New for AY 2026-27: Payments to MSME entities that remain unpaid beyond the prescribed due date, with tracking of prior-year disallowed amounts

If you have not deposited statutory dues within the prescribed time, the deduction is disallowed. For MSME payments, delayed payments beyond 45 days attract disallowance under Section 43B(h).

Clause 34: TDS/TCS Compliance

This clause requires reporting of tax deducted at source (TDS) and tax collected at source (YCS). The tax department cross-verifies this with Form 26AS and TRACES data. 

Mismatches between your books and the department’s records are a major red flag. Even small discrepancies can trigger notices asking for explanations.

Clause 44: GST Reconciliation

Clause 44 requires a detailed break-up of expenditure relating to GST registered and non-GST registered suppliers. This is one of the most challenging clauses to comply with, and the tax department uses it to identify GST compliance gaps. You must segregate:

• Expenses to GST-registered suppliers
• Expenses to non-GST registered suppliers
• Expenses relating to exempt goods or services
• Payments to composition dealers

The total of all these categories must match your profit and loss account expenditure total. Even a ₹1 difference can trigger scrutiny from the tax department. Businesses that run a proactive GST compliance audit throughout the year, rather than only at tax audit time, generally find this reconciliation far less painful in March

GST Reconciliation Requirements Within Form 3CD

Clause 44 asks for a break-up of your total expenditure based on the GST registration status of your suppliers. It requires the break-up for both entities registered and not registered under GST. 

After being kept on hold for a couple of years, reporting under this clause became mandatory for tax audit reports filed after March 31, 2022.

The table asks for seven columns of data. Most auditors work with these categories:

What To Report	Where it Goes
Total expenditure for the year, including capital expenditure	Overall total
Expenditure with GST-registered suppliers, split by exempt supplies, composition dealers and other taxable supplies	Registered-entity columns
Expenditure with unregistered suppliers	Unregistered-entity column

The total of the registered and unregistered entity columns should tally with the total expenditure figure reported. Certain items get excluded from this exercise entirely. 

Depreciation under Section 32 and bad debts written off under Section 36(1)(vii) are not actual expenses and should not appear in any of these columns. 

Transactions treated as neither a supply of goods nor a supply of services under Schedule III of the CGST Act, such as employee salaries, are also excluded.

Here is where the reconciliation gets tricky: GST returns like GSTR-3B and GSTR-9 report figures based on inward “supplies,” while Clause 44 is built around accounting “expenditure.” These are not always the same number. 

A prepaid expense, provision, or purchase recorded in one financial year but invoiced under GST in another can cause mismatches during a line-by-line comparison.

Your auditor will usually prepare a separate working paper that bridges the GST return data with the books, rather than lifting figures directly from GSTR-3B.

To make this clause easier to manage, keep a record of your suppliers’ GST registration status, identify composition scheme vendors separately in your accounting system, and clearly classify capital and revenue expenses throughout the year.

Businesses that perform this reconciliation every month alongside their GST return filing save a lot of time compared to those who postpone it until audit season.

Documentation Your Auditor Needs for Each Clause

A tax audit is faster and cleaner when your paperwork is ready before the auditor asks for it. Different clauses need different supporting documents and organizing these in advance is one of the most useful things you can do as a business owner.

For the basic clauses (Part A and books of account, clauses 1 to 12): Keep your PAN, registration certificates, list of books maintained and the accounting software details ready. 

For stock and valuation clauses: You need your closing stock valuation method, physical stock verification records and any deviation from the standard method along with its profit impact.

For the disallowance and compliance clauses covered earlier, use this checklist: 

• Clause 21: Ledger extracts for penalties, fines and any legal settlements, along with Form 26A certificates where TDS was not deducted but the payee has since paid tax.
• Clause 26: Proof of payment dates for statutory dues like PF, ESI, bonus and any Section 43B items, matched against your return filing due date.
• Clause 34: TDS/TCS return acknowledgments (Form 26Q, 27Q, 24Q), challan copies and a reconciliation between books and TRACES data.
• Clause 44: Supplier-wise GST registration status, GSTR-3B and GSTR-9 copies and a working paper reconciling expenditure with inward supply data.

Beyond these, most auditors also ask for loan and deposit records to check compliance with Sections 269SS and 269T (cash limits on loans), related-party transaction details for Section 40A(2)(b) and any transfer pricing documentation if you deal with associated enterprises. 

If you have opted for a presumptive taxation scheme and are now moving out of it, keep your income computation from the current and prior years handy, since that comparison feeds directly into the relevant clause.

Remember this key principle: Every “yes/no” response should be supported by figures and should be backed by a clear document trail, not just data entered into a spreadsheet.

Auditors are not permitted to certify particulars they cannot verify, so incomplete documentation usually means either a delayed report or a qualified one.

Common Mismatches Between Form 3CD and the ITR

Form 3CD and your Income Tax Return (ITR) should present the same financial information from different perspectives. Form 3CD reflects the auditor’s verification, while the ITR shows your computation of taxable income. 

If the figures do not match, the mismatch is detected when your return is processed, as the tax department electronically compares the audit report with the ITR.

Here are the most frequent mismatched areas: 

• Turnover and Gross Receipts: Your turnover as per Form 3CD must match the turnover reported in your ITR and GST returns. Even minor differences can trigger questioning. Reconcile early and document the reasons for any differences.
• TDS and TCS Compliance: Clause 34 of Form 3CD requires TDS/TCS details. The department cross-verifies this with Form 26AS and the TDS returns filed by deductors. If your books show payments to a party but Form 26AS does not reflect TDS deduction, you may face disallowance of the expense.
• Statutory Dues Under Section 43B: Clause 26 requires reporting of statutory dues. If you have claimed a deduction for unpaid PF, ESI, or GST that was not deposited within the due date, this will appear as a mismatch.
• GST Data: Clause 44 requires expenditure bifurcation based on supplier GST registration. This must reconcile with your GSTR-3B, GSTR-1, and GSTR-9 returns. The department uses this data to identify potential GST evasion or under-reporting of turnover.
• ITC Availability: Your input tax credit claimed must match the credit available in GSTR-2A/2B. Any ITC claimed on ineligible expenses will be disallowed.

Reconciling Form 3CD and the ITR is mainly a matter of proper timing and coordination. A good practice is to finalize Form 3CD first, have your CA review and sign off on it, and then prepare the ITR using the same figures. 

This helps avoid inconsistencies that can arise when both documents are prepared separately. Businesses that handle Form 3CD and the ITR independently without a final cross-check are more likely to receive reconciliation notices after filing.

FAQs

Q1: What is the difference between Form 3CA, 3CB, and 3CD?

Form 3CA and Form 3CB are audit report formats. Form 3CA applies if your accounts are already audited under another law, like the Companies Act. Form 3CB applies if they are not. Form 3CD is the 44-clause statement of particulars attached to whichever of the two applies to you.

 Q2: Which clauses in Form 3CD are most commonly flagged by the department?

Clauses 21, 26, 34 and 44 draw the most attention. They cover disallowed expenses, Section 43B payments, TDS/TCS compliance and GST-wise expenditure break-up, each of which requires cross-checking against a separate compliance record.

 Q3: Does Form 3CD need to reconcile with GST returns?

Yes, specifically clause 44, which needs your expenditure broken up by supplier GST status. GSTR-3B and GSTR-9 use a “supply” basis while clause 44 uses an “expenditure” basis, so a working reconciliation is usually needed rather than a direct figure copy.

 Q4: Who is responsible for signing off on Form 3CD – the business or the auditor?

Your chartered accountant (CA) signs and certifies Form 3CD. But the business is responsible for the accuracy of the underlying data, books, GST filings and TDS records, that the auditor relies on to prepare it.

 Q5: What happens if there’s a mismatch between Form 3CD and the ITR?

The department’s systems cross-check audit report data against your ITR electronically. A mismatch, such as an unreported disallowance or a turnover difference, typically results in a notice asking you to reconcile or explain the gap.

 Q6: How early should Form 3CD preparation start before the audit deadline?

At PKC Management Consulting, we recommend starting two to three months before the filing deadline, especially for clause 44 and TDS reconciliation, since these need supplier-wise and quarter-wise data that takes time to compile accurately.
