Condonation of delay in an appeal requires demonstrated sufficient cause, bona fides and due diligence. Pursuing remedies against a consequential assessment, while accepting revisionary adjustments and not challenging them within limitation, does not establish sufficient cause for a substantial delay. Maintainability also requires a genuine grievance against the order appealed from. Where appeal grounds challenge only the consequential assessment and expressly raise no objection to the revision order, an appeal against the revision order is not maintainable. The revisionary order consequently remains unassailed and cannot be used to contest the consequential assessment.

Engineering design review services fall outside fees for included services under Article 12(4) of the India-Canada tax treaty where project-specific drawings, inputs and reviews do not enable the Indian recipient to independently apply technical knowledge, skill, know-how or processes in future projects. They also do not amount to a transferred technical plan or design capable of independent use. The consideration is not royalty under section 9(1)(vi) or Article 12(3) where no right to use intellectual property or designs is granted and the materials remain confined to the particular project.

Share capital and share premium additions as unexplained cash credits cannot rest solely on subscribers' non-response to verification notices where the taxpayer has furnished names, addresses, PANs, bank details, tax returns and audited financial statements establishing identity, creditworthiness and genuineness. Effective contrary inquiry is required before disregarding that material; the addition was therefore deleted. For assessment years preceding 2021-22, the amended reassessment regime preserves the earlier limitation period. The extended limitation cannot revive reassessment proceedings already time-barred under the former six-year period, rendering the reassessment notice and consequential proceedings invalid.

Functional comparability in transfer-pricing benchmarking requires exclusion of software entities performing enterprise transformation, product sales, onsite services, product development, or research and development activities where their functions materially differ from routine software development support services. Two other entities providing substantially similar software services require fresh comparability review. Eligibility of another proposed comparable requires verification of related-party transactions against the applicable 25% filter. Working capital adjustment claims for software development support and sales and marketing support services require fresh examination. Benchmarking must be recomputed after the exclusions and fresh determinations.

Reassessment jurisdiction requires service of notice under section 143(2) where the Assessing Officer has taken cognisance of the return and proposes additions beyond returned income. Service of notice under section 148 and notices under section 142(1) does not substitute for the mandatory scrutiny notice. Completion of assessment under section 144 cannot cure the absence of this jurisdictional requirement. Consequently, reassessment completed without a valid notice under section 143(2) is void from inception and cannot be sustained.

Section 115BBE's enhanced tax rate applied only to transactions occurring on or after 1 April 2017 and could not govern the impugned addition for assessment year 2017-18. Tax effect therefore required computation at the normal rate, rather than the enhanced rate. Because that computation fell below the monetary threshold prescribed for departmental appeals under the applicable CBDT circular, the Revenue appeal was not maintainable.

Under the post-1 April 2021 reassessment regime, the approving authority under Section 151 depends on the time elapsed from the end of the relevant assessment year. Where a Section 148 notice is issued after three years, Section 151(ii) requires prior approval from the Principal Chief Commissioner, Principal Director General, Chief Commissioner or Director General. Approval by the specified authority is a jurisdictional prerequisite. Approval by a Principal Commissioner after this period does not meet Section 151(ii); consequently, the reassessment notice and resulting reassessment order were invalid and quashed.

Section 14A read with Rule 8D did not permit expenditure disallowance for Assessment Year 2017-18 where no dividend or other exempt income was earned. The amendment extending disallowance to situations without exempt income applies prospectively from Assessment Year 2022-23 and does not govern earlier assessment years. Accordingly, no Section 14A disallowance could be made in the absence of exempt income, and the disallowance was deleted.

TDS default claims involving commission paid to overseas agents without a permanent establishment in India require factual verification where supporting material on commission payments and tax deduction is available. Technical rejection of objections merely because they relate to the original TDS order rather than the rectification order does not address whether the payments attracted withholding tax. The matter was restored to the Assessing Officer to verify the evidence and decide afresh after allowing a final opportunity to substantiate the claim.

Penalty proceedings for alleged cash-receipt violations under Section 269SS could not be validly initiated under Section 271D solely on information received by the Joint Commissioner where no scrutiny assessment, reassessment, or other assessment proceeding was pending. In the absence of a regular assessment and recorded satisfaction by the Assessing Officer regarding the alleged contravention, the initiation lacked the required basis and was invalid. The penalty proceedings were consequently quashed.

Eligibility for approval under section 80G depends on an institution's dominant objects, beneficiary class and actual activities, not merely on disseminating spiritual or philosophical teachings. Objects promoting indigent relief, medical relief, public libraries, public welfare and moral advancement, available without distinction of class, caste or community, do not establish advancement of a particular religion. Religious expenditure is permissible up to 5% of total income; a clerical Form 10AB entry matching total audited expenditure should not be treated as religious expenditure where the actual Mandir Pooja expenditure remains within that ceiling. Donations therefore qualified for recognition under section 80G.

Section 68 applies to any sum credited in an assessee's books and is not limited to physical cash. Capital introduced through the recorded value of jewellery or precious items therefore falls within the unexplained-credit provision, without an exemption for personal assets. Material showing that the items arose from gifts received on the assessee's marriage and ancestral property inherited on a parent's death can satisfactorily explain their source. A valuation report affected by technical filing difficulties and an acceptable explanation for absent wealth-tax returns support treating the capital accretion as explained; an unexplained-credit addition is consequently unsustainable.

Penalty for under-reporting income attributable to misreporting requires establishment of a statutory circumstance of misreporting. Where an international transaction was disclosed in Form 3CEB, prescribed transfer pricing records were maintained, and the adjustment resulted solely from replacing the taxpayer's benchmarking method with another Most Appropriate Method, misreporting is not established without evidence of misrepresentation, suppression, or non-reporting. Eligible transfer pricing adjustments are excluded from under-reported income where prescribed conditions are satisfied. A penalty for misreporting was therefore unsustainable because the relevant statutory basis and factual circumstances were not identified or proved.

Rectification of an apparent typographical error may expressly include omitted R&D support services without reopening the merits. Transfer-pricing verification of R&D and other support-service payments must remain confined to the limited disallowance under examination and cannot treat acceptance of a percentage of payments as an approved ad hoc arm's length price. Arm's length price must be determined on relevant and reliable material using a prescribed, most appropriate method. Where the Other Method is unreliable, consideration may be given to another suitable prescribed method, including the Transactional Net Margin Method.

Transfer-pricing benchmarking of finished-goods purchases requires comparables supported by reliable, verifiable financial data. Trading entities reported with commercially implausible gross-profit-to-sales margins of 100% or more, without available profit-and-loss accounts to verify the calculations, should not remain in the comparable set. A trading company's annual report, where furnished and demonstrating no manufacturing activity, supports its inclusion as a comparable. Gross-profit calculations must also reflect an actual gross loss as a negative margin rather than a positive profit margin. Fresh benchmarking is required after correcting the comparable set and margin computation.

Software development services benchmarked under TNMM require comparables aligned with a captive, limited-risk service provider's functions, asset profile and revenue streams; companies undertaking complex end-to-end product engineering, lacking reliable segmental data, or breaching the related-party transaction filter are unsuitable. Delayed trade receivables intrinsically linked to the service transaction affect working capital and profitability. Once a working-capital adjustment is granted, their effect is already reflected in the TNMM analysis, so no separate notional-interest adjustment is warranted. The comparable set, assessed income and consequential demand require recalculation, subject to limited financial verification for one comparable.

TNMM benchmarking requires comparables that match the tested party's functions and risk profile. For a routine rice trader, companies engaged in milling, processing or manufacturing introduce margins linked to different assets and risks and should be excluded; a predominantly trading company requires assessment using segmental data. Cash discounts linked to purchase costs and export-incentive proceeds from licence sales are operating items when they arise from normal business operations. Excluding such receipts can distort a like-to-like operating-margin comparison. The benchmark is recomputed using functionally comparable entities and those business-linked receipts as operating income.

Section 144C(13) requires the final assessment to be completed within one month from the end of the month in which Dispute Resolution Panel directions are received. Uploading those directions on the ITBA portal constitutes valid service for calculating that limitation period. Where the directions were uploaded on 28 October 2025, the assessment had to be completed by 30 November 2025. A final assessment order issued on 24 December 2025 was therefore time-barred and without jurisdiction.

Final assessment orders under section 144C must conform to Dispute Resolution Panel directions; a consciously adopted adjustment exceeding those directions is invalid and cannot be cured by rectification. For intra-group technical and shared services, transfer-pricing analysis must determine the arm's length price using a prescribed method, not assess commercial expediency or expenditure allowability. Rule 10AB requires the Other Method to consider prices in same or similar uncontrolled transactions between non-associated enterprises. Where no comparable uncontrolled transaction or methodology supports a nil price, the nil valuation and resulting transfer-pricing addition lack a lawful benchmarking basis and require deletion.

Section 194C applies only to payments for work carried out under a contractual arrangement. Statutory market fees and Government-sanctioned procurement disbursements, where rates and expenditure components are predetermined and funds are routed to procuring societies or market committees, are pass-through payments rather than consideration under a contractor or subcontractor arrangement. Such payments therefore fall outside withholding-based disallowance under section 40(a)(ia). Section 41(1) applies only where a trading liability previously allowed as a deduction has resulted in a benefit through remission or cessation during the relevant year. Outstanding creditor balances remain non-taxable where liabilities continue to be recognised and there is no waiver, write-back, remission or legal extinguishment.
