Tax Audit Season: The Form 3CD Clauses That Cause the Most Trouble

Form 3CD runs to more than forty clauses, and most of them are mechanical: figures that come straight off the books or out of the client's records with little judgement attached. The audit does not run late because of those. It runs late because of a small number of clauses that require data the accounting system does not hold in the shape the form wants, and that data has to be assembled from GST returns, TDS returns, vendor masters, and payment records that were never designed to talk to each other. With the audit report deadline at the end of September and the return for audit cases a month behind it, the difference between a comfortable season and a bad one is usually decided in August.

Clause 44: The GST Expenditure Break-Up

Clause 44 asks for the total expenditure incurred during the year, split by the GST status of the supplier: expenditure on entities registered under GST, broken further into purchases from composition dealers, exempt supplies, and other registered entities, and expenditure relating to entities not registered under GST. It has applied since AY 2022-23 and remains the single most time-consuming clause in the form.

The difficulty is structural rather than conceptual. Total expenditure here means all expenditure, not just what appears in the purchase ledger, so it takes in salaries, statutory payments, depreciation, and every other charge, most of which have no GST character at all and belong in the unregistered or non-GST column. Meanwhile the accounting system is organised by nature of expense, and the clause wants it organised by counterparty GST status. Bridging the two means tagging vendors, which is straightforward for a business with two hundred suppliers and genuinely painful for one with several thousand.

• Start from total expenditure per the profit and loss account, then reconcile downward to what you have classified, so nothing is silently dropped.
• Tag the vendor master with GST registration status once, and reuse it, rather than classifying transaction by transaction each year.
• Treat salaries, statutory dues, depreciation, and provisions explicitly rather than leaving them to fall through the classification.
• Reconcile the registered-supplier total against inward supplies reflected in GST returns, and document the differences rather than forcing agreement.
• Keep the working paper that ties the clause back to the audited figures, since that reconciliation is what gets asked for later.

Clause 34: TDS Compliance, and the Disallowance Behind It

Clause 34 requires reporting of tax deductible but not deducted, deducted but not deposited within time, and returns filed late or with incorrect particulars. It matters more than its position in the form suggests, because what it reports flows directly into a disallowance: expenditure on which tax was deductible but not deducted attracts disallowance under Section 40(a)(ia), which increases taxable income regardless of how sound the expense itself was.

The reconciliation that surfaces problems is between expense heads that ordinarily attract deduction, professional fees, contract payments, rent, commission, interest, and what actually appears in the TDS returns for the year. Gaps typically arise where a payment was recorded under an unusual head, where a vendor was treated as exempt on the basis of a certificate that was never obtained, or where a threshold was crossed mid-year and earlier payments were never revisited. The related detail worth checking alongside it is whether deduction happened at the right rate and at the right point, since deducting late is a different defect from not deducting at all and carries its own interest. Our guide to TDS return filing across 24Q, 26Q, and 27Q covers the underlying filings this reconciles against.

Clause 26 and Section 43B: Paid, Not Merely Provided

Clause 26 deals with statutory dues covered by Section 43B, where deduction is allowed on actual payment rather than on accrual. Provident fund, ESI, GST, customs duty, bonus, leave encashment, and interest on certain borrowings all sit here. The clause asks what was outstanding at the start of the year, what was paid during it, and what remains unpaid, and the reporting drives whether the deduction survives.

Two traps recur. The first is employee contributions to provident fund and ESI, which are treated far more strictly than the employer's own share: deposited even slightly beyond the due date under the relevant labour law, they are disallowed outright rather than merely deferred. The second is the assumption that paying before the return filing date always rescues a deduction. It does for the dues to which that relief applies, but it is not a universal solvent, and applying it too broadly is how disallowances get missed at audit and discovered later.

The MSME Payment Disallowance Under Section 43B(h)

The newest source of difficulty is the disallowance for delayed payments to micro and small enterprises. Where a buyer has not paid a registered micro or small supplier within the period allowed under the MSME Development Act, the deduction for that expenditure is denied for the year and pushed to the year of actual payment. This turns a commercial delay into a direct and immediate tax cost, and it is the clause most likely to produce an unwelcome surprise at the year end.

The practical problem is identification. The disallowance depends on the supplier's registration status as a micro or small enterprise, which the buyer's accounting system has no reason to record, and on whether payment fell within the statutory window, which requires matching invoice dates to payment dates supplier by supplier. Businesses that collected Udyam registration details from vendors in advance handle this in an afternoon. Those that did not spend the audit chasing declarations from suppliers who may not respond. Our post on the MSME 45-day payment rule sets out the underlying obligation, and the MSME glossary entry covers how the classification itself works.

The Timeline, and Where to Spend August

The pattern across all four clauses is the same: none of them are difficult to report once the data exists, and all of them are difficult to gather in September. Vendor GST tagging, MSME declarations, and the TDS reconciliation are August work by nature, because each depends on someone outside the audit team responding. Confirm which entities actually require audit before any of this begins, since applicability itself is sometimes assumed rather than tested, and our post on Section 44AB applicability covers where the thresholds sit.
