Unverified purchases supported by invoices, banking payments, stock records, quantitative reconciliation and accepted sales cannot be wholly disallowed merely because named suppliers are suspicious or untraceable. Where stock movement and corresponding sales establish that goods were acquired, doubt about the actual supplier supports taxation only of any additional margin or savings from alternative sourcing. Undisclosed third-party material and incomplete transport details cannot conclusively override documentary and quantitative evidence. An ad hoc 10% addition without reference to trading margins, disclosed gross profit or comparable material is unsustainable. Only an additional gross-profit element of 2% of disputed purchases, beyond disclosed gross profit, is taxable.

Retracted survey admissions cannot alone displace profits disclosed in audited books where no defects or corroborating material are identified. Unsecured loans are not unexplained cash credits where confirmations, lenders' income-tax returns and bank statements establish the transactions, particularly when repayment occurs during the relevant year. Contractual expenditure is not disallowable merely for short deduction of tax at source; disallowance applies where tax is not deducted. Capital introduced is explained where bank records trace it to withdrawals from the taxpayer's proprietary concern. These principles render the respective additions unsustainable and require recomputation of income.

Penalty notices under Section 274 read with Section 271(1)(c) must clearly identify whether the alleged default is concealment of income particulars or furnishing inaccurate particulars. Retaining both statutory limbs without deleting the inapplicable charge fails to give the assessee clear notice of the accusation and impairs the opportunity to respond effectively. This defect invalidates the initiation of penalty proceedings, and a consequential penalty order cannot be sustained.

Fully disclosed claims for deduction of employees' PF and ESI contributions do not constitute under-reporting of income merely because subsequent judicial clarification requires deposits within statutory due dates. Section 270A penalises under-reporting, whereas section 36(1)(va) governs deductibility of employees' contributions. Disclosure in the tax-audit report, books and return, coupled with a claim consistent with the then-prevailing legal position, means that a later disallowance does not establish under-reporting or inaccurate particulars. Penalty under section 270A is therefore unsustainable on those facts.

Unsecured-loan additions require contrary material where creditor identity, financial capacity and transaction genuineness are supported by tax, banking and confirmation records; suspicion about preceding cash deposits alone is insufficient. Purchase inflation cannot be inferred by comparing purchased rice with closing stock where the purchased goods were sold and closing stock comprises manufactured rice consistently valued at lower of cost or market value. Estimated yield-based additions require valid rejection of books of account before best-judgment assessment. Cash purchases from farmers may be verified through contemporaneous registers, gate passes and vouchers, particularly where audited records correlate purchases, production and sales. Additions lacking evidentiary or legal foundation are unsustainable.

Transfer-pricing margins under the Transactional Net Margin Method treat trade-receivable bad-debt provisions, rates and taxes, business-related receipts, and deferred operating-revenue amortisation as operating items. Comparable selection requires functional, asset and risk analysis, uniform related-party transaction filtering, and exclusion of entities affected by extraordinary events, high-end functions, or materially different scale. Distribution adjustments remain limited to associated-enterprise transactions and use gross-margin comparison under the Resale Price Method. Working-capital differences require average-balance analysis. Delayed associated-enterprise receivables do not warrant notional interest without demonstrated financing cost, arrangement, or benefit. Intra-group services cannot be priced at nil without valid method selection, comparability analysis, or evidence of shareholder activity; the segmental computation requires recomputation accordingly.

Interest on qualifying tax-free bonds remains exempt even where it was mistakenly disclosed as taxable income in the return. Rectification is available where the erroneous classification is apparent from the record, particularly when the interest was consistently treated as exempt in other years. Correcting such an error does not amount to making a fresh claim; it gives effect to the statutory exemption. Expiry of the period for filing a revised return does not prevent correction of an apparent mistake through rectification.

Surcharge on income of a private discretionary trust taxable at the maximum marginal rate must be computed by reference to the applicable surcharge slab in the First Schedule to the Finance Act, 2023. Applying a higher surcharge rate without reference to the relevant slab is incorrect. The surcharge liability therefore requires recomputation using the applicable slab rate.

Revision under Section 263 requires an assessment order to be both erroneous and prejudicial to the Revenue; a legally permissible assessment view cannot be displaced merely because further enquiry or another view is preferred. ESOP discount arising from employee compensation may qualify as business expenditure under Section 37(1) when liability crystallises. Revision concerning branding fees requires prior notice. Section 14A and Rule 8D disallowance cannot be mechanically imported into Section 115JB book profit; actual expenditure relatable to exempt income requires independent determination. Deemed dividend requires the lender's shareholder to hold the prescribed legal membership or partnership interest in the recipient concern; indirect economic interest alone is insufficient.

Section 54F relief is available where sale consideration is applied towards an allotted residential unit and the unutilised balance is deposited in the Capital Gains Account Scheme before the return-filing due date. Advance payment under a purchase agreement and a timely statutory deposit are deemed to form the cost of the new asset. A projected RERA completion date beyond three years does not by itself defeat relief at the assessment stage; any amount ultimately left unutilised becomes taxable only in the prescribed later year. Two flat numbers forming one composite duplex on consecutive floors constitute a single residential house.

Lump-sum premium paid to acquire leasehold land rights is capital expenditure, not advance rent; therefore, amortisation under Section 37(1) is unavailable. Such leasehold rights are neither specified intangible assets nor comparable business or commercial rights for depreciation under Section 32(1)(ii), and consistency with earlier identical determinations supports denial of both claims. Profits of overseas branches in treaty jurisdictions remain includible in an Indian resident's taxable income and must be computed under the Income-tax Act. The "may be taxed" notification applies beyond non-business income; double-tax relief is instead available through foreign tax credit under Sections 90 and 91, not exclusion or exclusive foreign-law computation.

Section 69 requires positive material showing that an assessee funded an investment from unrecorded sources; joint ownership, without proof of payment from unexplained funds, is insufficient. Connected property-transfer instruments concerning the same flat may evidence a single transaction rather than separate investments, particularly where loan records explain the consideration. Absence of effective notice or knowledge may constitute sufficient or reasonable cause for delayed appeals and non-compliance. Where an unexplained-investment addition lacks support, penalties for notice non-compliance, failure to file a return, and concealment require independent statutory and factual foundations; a concealment penalty cannot rest solely on a deleted quantum addition.

Revision under Section 263 requires an assessment order to be both erroneous and prejudicial to the interests of the Revenue. Where the assessing officer specifically sought details of Chapter VI-A deductions, examined donation receipts and supporting evidence, and recorded their review, the absence of a separate discussion of Section 80G does not establish non-application of mind. A revisional objection concerning the sufficiency of enquiry cannot be substituted for a finding of complete lack of enquiry. Further, where the allowability of eligible CSR-related donations under Section 80G supports plausible divergent views, adoption of one such view does not make the assessment order erroneous. Revision is therefore invalid in these circumstances.

Binding jurisdictional High Court precedent requires tax authorities to treat the absence of an express irrevocability clause as no bar to a public charitable trust's registration and consequential donor-tax approval, unless that precedent is stayed, modified or reversed. Registration and approval must be assessed under the law in force when granted. Neither the registration provisions nor procedural rules support attaching a contingent condition merely because Revenue proposes a challenge before a superior court. Registration and approval therefore operate without qualifications based on a possible future ruling.

Reasonable cause shields an assessee from penalty for non-compliance with statutory notices where the default is not deliberate. Penalty should not be imposed mechanically for a technical failure to respond; the explanation, surrounding circumstances and evidence of knowing disregard require independent assessment. Failed physical service, returned postal communications, ex parte proceedings, lack of knowledge of electronic proceedings and absence of assistance may establish reasonable cause. These circumstances rendered the penalty for notice non-compliance unsustainable and liable to deletion.

Arm's length pricing of intra-group support services requires a recognised transfer-pricing method and objective comparable analysis; dissatisfaction with a benefit test alone cannot justify a nil value. Communications, agreements, cost-allocation workings and personnel details may establish actual services and business nexus. Functional overlap does not prove duplication without item-wise examination, and a component of transactions benchmarked together under TNMM cannot be assigned a nil value without a proper basis. The nil valuation, transfer-pricing adjustment and alternate business-expenditure disallowance were deleted. Interest under Section 234C must be computed on tax due on returned income and recomputed accordingly.

Contractual interest on compulsorily convertible debentures requires arm's-length pricing through comparable uncontrolled transactions or other prescribed comparability analysis. Future compulsory conversion, a long tenor, and no cash-redemption right may affect comparability and warrant adjustments, but do not alone recharacterise a subsisting interest obligation as equity or support a nil price. Departure from legal form requires facts showing different economic substance or impracticable reliable pricing. Interest on unconverted debentures may constitute capital-borrowing expenditure; disallowance requires an independently supported absence of business nexus or non-business use. Interest-limitation computations and statutory interest should reflect any revised assessment.

Inventory valuation must follow the consistently employed accounting method and measure net realisable value by conditions prevailing on or around the balance-sheet date. In a volatile market, annual average sale or purchase prices cannot substitute for the relevant date's market value; valuation follows the lower of actual cost or net realisable value. An express later prescription of that standard may clarify the principle inherent in the earlier framework. Closing-stock quantities should be verified from production registers and audited financial statements where an arithmetical error in Form 3CD produces an inaccurate quantity; reliable primary records prevail over that secondary reporting detail.

Interest on delayed remittance of tax deducted at source is not deductible as business expenditure merely because it is compensatory; the outlay arises from statutory default and fails the wholly-and-exclusively business-purpose requirement. Project establishment and supervision expenses may remain revenue expenditure despite capitalisation in the accounts, as accounting treatment is not conclusive for tax purposes. Disallowance relating to exempt income cannot be mechanically carried into book-profit computation. Capital-gains exemption for compulsory acquisition, transfer-pricing of captive-power supply, exempt-income disallowance, and foreign-exchange variation in inventory require fresh examination of the applicable conditions, comparables, expenditure, and underlying facts.

Income-tax deductibility turns on actual payment for specified duties, objective satisfaction before Rule 8D disallowance, and scientifically determined accrued liabilities rather than contingencies. Approved in-house R&D facilities support weighted deductions for eligible expenditure despite non-conclusive Form 3CL quantification; recurring technical-know-how royalty and related cess remain revenue expenditure. CSR costs are deductible before Explanation 2's effective operation but not where the statutory exclusion applies, although qualifying donations may receive separate section 80G relief. Investment-focused mutual-fund redemptions produce capital gains or losses, and industry-promoting sales-tax subsidy is a capital receipt. Offshore FOB purchases without Indian tax charge do not require withholding. Transfer-pricing adjustments require prescribed methods and reliable comparables, while creditor write-offs alone do not establish cessation of liability.
