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.

Corporate Social Responsibility contributions to eligible charitable institutions may qualify for deduction under Section 80G even though Explanation 2 to Section 37(1) excludes CSR expenditure from deduction as business expenditure. The exclusion for specified CSR expenditure does not extend to otherwise eligible charitable contributions under the separate Section 80G framework. Employee stock option plan discount is employee compensation incurred to obtain and retain services and may be allowed as revenue expenditure under Section 37(1). Market-value-based measurement and the absence of immediate cash outflow do not make the recognised liability capital or notional under the mercantile system of accounting.

In an unabated assessment, additions for unexplained cash credits under Section 153A require incriminating material found during search. Seized Tally data, bank-ledger entries and corroborative statements directly linked the taxpayer to unaccounted cash receipts, supporting the additions. Cash credits described as land advances remained unexplained because the taxpayer did not establish the payers' identities, provide confirmations or agreements, or otherwise substantiate their nature and source; book entries and audited accounts were insufficient. A consequential assessment pursuant to an operative revision order was not annulled. Telescoping was unavailable because no nexus was proved between the disputed credits and income considered in settlement proceedings.

Tax deduction at source on sales commission paid to foreign agents applies only where the remittance is income chargeable to tax in India. Commission paid to agents operating outside India, without a business connection or establishment in India, for services rendered abroad and received abroad through authorised banking channels, neither accrues nor arises in India and is not received in India. Such payments therefore do not trigger withholding obligations, and consequential liability for failure to deduct tax at source is unsustainable.

The non-quantifiable or uninvolved tax-effect exception under CBDT monetary-limit circulars does not permit a departmental appeal where reassessment has already determined a specific tax liability. Setting aside that assessment on a legal ground does not make the tax effect unquantifiable. The exception applies where tax consequences cannot presently be computed, including exemption-registration matters or revisional orders requiring fresh assessment. Where the quantified liability remains below the applicable threshold, the departmental appeal is not maintainable.

Further opportunity to furnish Forms 15G/15H is required where an appellate direction mandates their verification before recomputing interest-expenditure disallowance. Disallowance under the tax-deduction provisions must be recomputed only after the Assessing Authority examines all relevant forms, including outstanding forms the assessee undertakes to supply. The forms' genuineness may be verified before a fresh consequential order is issued in accordance with the appellate direction.

Direct authorisation to represent a company in GST refund proceedings, supported by a power of attorney, recorded appearances and fee correspondence, establishes professional engagement and agreed consideration. An alleged condition making fees payable only upon a successful refund cannot qualify the payment obligation unless agreed. An intermediary is not a necessary party where the client directly granted authority and engaged the professional. Recovery of the agreed fee follows from the established mandate and services rendered; pendente lite and future interest fall within the court's discretion under the Code of Civil Procedure, while litigation costs may be separately determined.

Supply, erection, testing and commissioning of a fire protection system constitute a composite supply where equipment and related services are naturally bundled with a principal supply. Permanent installation through site preparation, RCC platforms, wiring, pipework and commissioning creates immovable property where removal requires substantial dismantling. Transfer of goods in creating that immovable infrastructure falls within works contract and is treated as a supply of services, classifiable under SAC 9954. The claimed concessional 12% works-contract rate does not apply where earthwork is negligible and the statutory predominant-earthwork condition is not met.

Physical verification of goods may test whether quantities actually transported match the invoice, e-way bill, source records and documentary trail; those documents do not prevent such verification. Supplier-wise and aggregate weight discrepancies require cumulative assessment where they are unsupported by contemporaneous objections, independent weighment reports or technical evidence challenging departmental measurements. Repeated generation and cancellation of e-way bills by different entities for the same invoice number and quantity may reinforce unreconciled discrepancies and indicate an intent to evade tax. On these facts, setting aside tax and penalty under Section 129(3) was unsustainable, and restoration of the original tax and penalty order was warranted.

Goods in transit must carry contemporaneous documents and e-way bill details that match the physical consignment. Documents relating to different commodities, unsupported explanations of document exchange, and invoices produced only after detention do not establish compliance retrospectively. Where no valid documents identify a bona fide owner at interception, subsequent ownership claims do not displace the transporter's liability as a person other than the owner. For undocumented goods lacking matching invoices and traceable buyers, valuation based on product quality, specifications, and prevailing wholesale-market averages may provide a rational basis. Seizure-related penalty consequences remain sustainable on these grounds.

Portal downtime preventing contemporaneous e-invoice generation does not, by itself, justify a penalty under Section 129 where an e-way bill, commercial invoice and delivery note establish transparent movement of goods and no intent to evade tax exists. E-invoicing requirements must be applied consistently with Rule 55(4) and the principle that law does not compel impossibility; mens rea is necessary for the penalty. Payment through DRC-03 to secure release of detained goods under economic duress does not create estoppel against statutory appellate remedies, permitting refund with statutory interest where the penal demand fails.

Section 76(1) of the CGST Act requires every person who collects an amount representing tax to remit it to the Government, regardless of registration status, supply taxability, or whether the collection exceeds tax otherwise payable. Invoices, GSTR-1 disclosures, credit passed to recipients, and bank remittances may establish actual collection, creating an obligation to deposit the amount. Section 16(4) imposes a time limit for availing input tax credit; delayed GSTR-3B filing does not permit use of time-barred credit through the Electronic Credit Ledger to discharge tax liability. Non-remittance and invalid credit utilisation attract applicable fiscal consequences.

Section 122 penalties may apply where taxpayers falsify financial records, create fake invoices or documents, furnish false returns with intent to evade tax, or avail or use input tax credit without actual receipt of goods. A voluntary, unretracted statement obtained in a statutory inquiry may establish fraudulent credit unless duress or coercion is shown. Credit eligibility requires proof of actual receipt of goods and supplier tax payment, with the taxpayer bearing the evidentiary burden. Unreliable movement records, invalid vehicle details and unproven supplies may defeat that claim. Appellate reliance on material not produced before the adjudicating authority requires justification under the applicable procedural rule.

Section 39(9) permits correction of omissions or incorrect particulars in the return for the period in which the error is noticed, including a later return within the same financial year, subject to the statutory deadline and provided the correction does not arise from scrutiny, audit, inspection or enforcement activity. B2B supplies mistakenly reported as B2C and subsequently re-reported as B2B can duplicate entries in Form GSTR-1, inflating reported turnover and tax liability where tax was already paid through Form GSTR-3B. A timely voluntary correction is revenue-neutral, and the resulting GSTR-1/GSTR-3B variance does not establish additional tax liability.

Job-work movements under section 143 permit a principal's goods to move for processing and return under delivery challans, while job-work charges may be separately invoiced. Under Rule 138, either the principal or, for inter-State job work, the registered job worker may generate the e-way bill; its generator and declared value do not alone establish a taxable supply. Where records show principal-owned goods were processed and returned, a return/e-way-bill mismatch requires independent evidence of undisclosed supply, consideration, or tax evasion. Without such evidence, GST, interest, and penalty cannot be sustained.

Input tax credit reversal for exempt cattle-feed supplies is limited to credit actually availed on common inputs, input services, or capital goods used for taxable and exempt supplies. Where no credit was taken on exempt traded goods, no reversal arises; any common input-services credit requires verification and proportionate computation under Rules 42 and 43. Annual-return figures may correct periodic-return declarations, so claimed clerical corrections and supporting records must be examined before differential tax is determined from a GSTR-1/GSTR-9 mismatch. Tax, interest, and penalty liability requires fresh merits determination after that verification and reconciliation, with an effective opportunity to submit evidence and be heard.
