Principles of natural justice require adequate opportunity of hearing before an appellate authority confirms an addition through an ex parte order. Where the taxpayer challenges the addition, seeks to produce supporting evidence, and the reasons for non-appearance cannot be ruled out, fresh appellate adjudication is required. The matter should be remitted so that relevant information may be presented and considered after providing a meaningful hearing opportunity.

Compliance with interim judicial directions prohibiting tax deduction at source on leave travel concession reimbursements involving a foreign travel leg prevented bank branches from being treated as assessees in default. Although the Section 10(5) exemption was unavailable for foreign travel, the directions operating during the relevant period displaced the Section 192 deduction obligation. Section 201(1) applies only where tax was required to be deducted and was not deducted; a subsequent merits determination could not retrospectively create a default. Consequently, interest under Section 201(1A) was not chargeable for that period.

Payments to non-resident service providers directly and inextricably connected with mineral-oil prospecting, extraction or production fall within the presumptive regime under Section 44BB. The mining-project exclusion from fees for technical services applies where the pith and substance of the agreement establishes that connection. Section 44BB consequently prevails over the general fees-for-technical-services computation mechanism under Section 44DA for qualifying contractual services. Tax deducted at the rate applicable to Section 44BB payments is therefore correct, and the payer is not an assessee in default on that basis.

Post-transfer receipts reflected in Form 26AS are not conclusively taxable to the PAN holder where substantive material shows that the underlying business and revenue transferred to a successor entity. Verification is required to confirm that the successor accounted for and was taxed on the receipts, and that the original entity did not claim the related TDS credit; verified duplicate taxation requires deletion of the addition and appropriate regulation of TDS credit. Advertising expenditure is deductible when invoices, publication evidence, payment records and TDS establish actual promotional services and business nexus. Related-party status, absent separate agreements, and no immediate revenue increase do not alone justify disallowance without proof of excessiveness.

For computing long-term capital gains under Section 48, the cost of acquisition of a constructed residential flat should include independently substantiated acquisition and construction expenditure, even where the registered conveyance records a lower amount. Contemporaneous housing-finance records, including loan disbursement, repayment and closure material, corroborate the additional cost and support applicable indexation; the recorded sale-deed consideration is not conclusive where the loan is not shown to be unrelated to the property. Reassessment based on property-sale information and non-filing of a return remains valid where an opportunity under Section 148A(b), an order under Section 148A(d), and notice under Section 148 were issued.

Revisionary jurisdiction under Section 263 requires an assessment order to be both erroneous and prejudicial to Revenue; it is not triggered merely because an assessing officer could have undertaken a more detailed enquiry after specifically examining and verifying a Section 80G claim. CSR expenditure disallowed in computing business income under Explanation 2 to Section 37(1) may nevertheless be considered separately for a Section 80G deduction from gross total income. Adding back the expenditure prevents double deduction, while eligibility for the charitable-contribution deduction remains subject to the statutory conditions, including any specific exclusion for designated funds.

Transfer-pricing benchmarking of an integrated IT-enabled/data analytics transaction must follow the selected most appropriate method under Section 92C and Rule 10C. Once the Residual Profit Split Method has been fully applied, a separate entity-level TNMM-type margin test for the same transaction is impermissible unless that method is rejected for cogent reasons and an alternative is selected. The separate integrated-services adjustment was deleted. Corporate guarantee pricing cannot mechanically use commercial bank-guarantee rates; an interest-saving analysis requires verification of credit profile, borrowing terms, currency, tenure, security, coverage and economic benefit. Guarantee remuneration was remitted for fresh evidence-based computation.

Allegedly non-genuine purchases linked to undisputed sales require an addition limited to the embedded profit element rather than the full purchase amount, following rejection of books of account under Section 145(3). The profit estimate should reflect the relevant facts and disclosed gross profit. Where materially similar facts and the same business existed in the immediately preceding year, with no factual distinction for the current year, a 5% profit rate applies instead of 12.5%.

Section 80GGC deduction was denied because banking-channel payment and donation receipts did not establish the political contribution's genuineness. Search material, office-bearer admissions, bank-account patterns showing fund routing through intermediary entities, and failure to meet statutory contribution-reporting requirements indicated an accommodation-entry arrangement. The human-probabilities and preponderance-of-probabilities tests gave greater weight to those surrounding circumstances and circumstantial evidence than to the taxpayer's documents. No credible rebuttal established that the payment was a genuine political donation.

Late fee under Section 234E could not be computed while processing TDS statements under Section 200A for periods before 1 June 2015. The amendment expressly enabling such computation operated prospectively from that date. With no jurisdictional High Court ruling and conflicting High Court views, the interpretation favourable to the assessee applied. Accordingly, late fee imposed for financial year 2012-13 through Section 200A was invalid and liable to be deleted.

Section 269SS prohibits accepting a specified sum, including an advance for transfer of immovable property, other than through prescribed banking modes. Section 273B excludes penalty under Section 271D where the recipient establishes reasonable cause. Transaction disclosure and genuineness alone do not establish reasonable cause, but prompt bank deposit of the cash advance, receipt of the balance consideration through banking channels, disclosure in the registered sale deed and income-tax return, personal financial need, and the purchaser's circumstances may cumulatively support a bona fide explanation. On those stated facts, reasonable cause excluded the penalty.

Section 12AB renewal requires an assessee to establish the genuineness of its charitable objects and activities, not merely produce constitutional documents or evidence of token activity. Donor source and identity information may be examined at renewal where it bears on authenticity, although conclusive taxation of anonymous donations generally belongs to assessment proceedings. Substantial cash donations lacking PAN or Aadhaar details, inadequate linkage between expenditure and identifiable beneficiaries, limited evidence of public benefit, and relevant management-related adverse information can collectively undermine genuineness. Earlier registration or past acceptance does not create a vested right to renewal. Failure to dispel such doubts supports refusal of renewal.

Section 195 requires tax withholding only where a remittance is chargeable to tax in India. Commission paid to a non-resident for services rendered outside India is not taxable in India where the recipient has no business operations, office, or permanent establishment in India and no sufficient nexus establishes Indian accrual. Absence of a Tax Residency Certificate may affect treaty relief but does not itself create a domestic tax charge. A Form 15CB description is not conclusive; the underlying agreement, invoices, and actual services determine the remittance's character. Consequently, no withholding obligation or disallowance arises where the commission is not chargeable in India.

Global-ranking support, institutional facilitation and coordination services are business activities for presumptive taxation under section 44AD where their substance consists of stakeholder coordination, data organisation, reporting, benchmarking and operational guidance. Section 44ADA applies only to professions listed in section 44AA(1), and contractual labels such as advisory or consultancy, or withholding under section 194J, do not determine classification. As these services were not any listed or notified profession, and did not constitute excluded commission, brokerage or agency business, section 44ADA could not support estimation of income at 70% of receipts. Income offered under section 44AD was therefore required to be accepted.

Retention money previously included in income and recorded as receivables meets the prior-inclusion condition for bad-debt deduction when actually written off as irrecoverable. Under the post-1989 rule, separate proof that the debt became irrecoverable in the particular year is not required. Related-party rent may be disallowed only to the extent it is excessive or unreasonable against the fair market value of facilities; suspicion, an assertion of lack of revenue neutrality, or absence of comparable evidence does not establish that condition. On those principles, disallowances of the written-off retention money and rent are unsustainable.

Section 68 additions for share capital, premium and unsecured loans were unsustainable where corporate subscribers and lenders provided verified identity, financial capacity, confirmations, audited accounts and banking records, including source-of-funds evidence where examined. Lack of adverse findings in remand verification, repayment of loans, and denial of cross-examination on an undisclosed inspector's report supported deletion of the additions. Under the Purpose Test, incentives intended to establish or expand industry, create employment and promote regional development were capital receipts rather than operational-profit supplements; they were excluded from normal income computation. Transport subsidy and VAT/CST remission, as receipts not constituting income, were also excluded from book profit for MAT.

Section 147 reassessment requires the Assessing Officer to form an independent reason to believe that taxable income has escaped assessment. Investigation-wing information concerning alleged circular transactions may prompt examination but does not alone establish escapement in an assessee's hands. Recorded reasons should demonstrate verification of the assessee's receipt of funds, role in relevant transactions, and satisfaction of the conditions for deemed dividend under Section 2(22)(e). Mere suspicion, without a prima facie nexus to escaped income, is insufficient.

Section 149 bars a reassessment notice issued more than three years after the relevant assessment year unless the extended-period conditions apply. The extended period requires alleged escaped income, represented by an asset, expenditure, or book entry, to amount to or likely amount to the prescribed statutory threshold. Where the notice for the relevant assessment year was issued after five years and the alleged escapement was below that threshold, it was time-barred. The reassessment proceedings were therefore quashed.

Reassessment under Section 147 may be based on Investigation Wing information concerning transactions and modus operandi where it does not rely on material seized in a third-party search; proceedings under Section 153C need not be invoked in those circumstances. Where purchases are doubtful or linked to accommodation-entry patterns, the addition may be confined to the profit element embedded in disputed purchases rather than the full purchase value. The stated approach sustains an addition of 6% of the disputed purchases.

Reassessment notices issued more than three years after the relevant assessment year require prior sanction from the specified higher authority; approval by a Principal Commissioner does not meet that jurisdictional requirement, invalidating the notice and consequential assessment. Where an original return is treated as filed in response to a reassessment notice, a notice under Section 143(2) is mandatory before assessment; its absence invalidates the assessment. Section 56(2)(vii)(b) does not apply where the agreement, full payment and possession of immovable property were completed before the provision took effect, notwithstanding subsequent conveyance registration.
