Penalty under Section 271AAA does not arise merely because physical stock of polished diamonds is lower than recorded book stock. Undisclosed income requires search material establishing income not recorded in the books. Where no search-based evidence proves that the stock discrepancy resulted from unrecorded sales or that sale consideration remained unaccounted for, the statutory conditions for penalty are not met. Confirmation of a quantum addition does not independently establish penalty liability, as penalty provisions require strict construction. The penalty was therefore deleted.

Redevelopment compensation paid to a flat owner for hardship and displacement during redevelopment is intrinsically linked to the capital asset and is not taxable merely because it is not spent on alternative accommodation. Taxable salary must be computed after admissible exemptions and deductions; Form 26AS gross salary cannot alone support an addition where Form 16 and settlement records reconcile the figures. A donation receipt supported by a corresponding bank debit supports deduction under section 80G absent evidence of ineligibility. Savings-bank interest included in gross total income qualifies for deduction under section 80TTA when within the statutory limit and derived from an eligible account.

Delayed electronic filing of Form 10B under section 12A(1)(b) is a procedural and evidentiary lapse, not a substantive failure, where the audit report was timely obtained, filed before the return deadline, and charitable exemption conditions are otherwise met. Such delay does not by itself defeat exemption under section 11; eligibility remains subject to verification and reconciliation with Form 10AC. The adjustment under section 143(1) did not breach natural justice where the variance schedule identified the delayed filing and the assessee had opportunities to address it during rectification and appellate proceedings.

Equivalent debenture subscriptions by an associated enterprise and an unrelated subscriber under substantially identical contractual terms, including a 15% interest rate, support use of the unrelated-party investment as a reliable internal comparable for arm's-length pricing. In the absence of material distinguishing facts, debt-equity recharacterisation producing a nil arm's-length price is not supported. Interest-limitation disallowance requires recomputation after verification of the correct associated-enterprise interest and EBITDA figures. Set-off of brought-forward business losses depends on verification of the eligible loss quantum, availability, and implementation of relevant appellate directions.

Natural justice requirements are met where statutory notices, replies, supporting material and a final opportunity are considered, with no identified material left unaddressed. Cash deposits lacking evidence of their source, repayment trail, cash book, withdrawals or deposit-wise reconciliation may be treated as unexplained money, attracting the consequential tax regime. Land-arrangement receipts reflect business income where ownership or acquisition of a capital asset is unproved and activities show commercial facilitation; unsupported refund claims do not create liabilities. GST disclosures are contemporaneous evidence of receipts unless rebutted through invoices, contracts, credit notes, ledgers or reconciliations. Tax treatment follows credible evidence and real commercial substance rather than unsupported labels or affidavits.

Section 56(2)(viib) applies where consideration is received for the issue of shares above fair market value. A securities-premium credit created solely by reclassifying compulsorily convertible preference shares under Ind-AS, without a fresh receipt during the year, does not constitute such consideration; taxing it may duplicate an earlier tax adjustment. A merchant banker's Discounted Cash Flow valuation prepared under Rule 11UA remains a prescribed basis for fair market value. Differences between projected and subsequent actual results alone do not invalidate that valuation or justify substituting the Net Asset Value Method when the valuer's competence and method are undisputed.

Section 69 unexplained-investment additions require a satisfactory explanation of the source of funds. Documentary confirmation of a gift, the donor's bank records evidencing liquidation of fixed deposits, and matching RTGS entries established the source and genuineness of funds applied to property investment; the addition was deleted. Bank debits, account credits, and the stated use of salary income and savings supported recurring mutual-fund contributions; that addition was also deleted. Credible documentary and banking evidence establishing funding sources prevents property and mutual-fund investments from being treated as unexplained.

Penalty proceedings for concealment of income or furnishing inaccurate particulars require a notice identifying the precise charge. Retaining both alternative limbs in a notice, without striking out the inapplicable limb, leaves the taxpayer unable to determine the alleged default. Under Sections 274 and 271(1)(c), this defect in initiation renders the notice invalid and prevents the consequential penalty order from being sustained. Clear communication of the applicable statutory basis is required before imposition of a penalty.

Interest earned by a co-operative credit society on its own funds temporarily placed in deposits with nationalised or scheduled banks is attributable to its business of providing credit facilities to members and qualifies for deduction under section 80P(2)(a)(i). "Attributable to" is broader than "derived from". Treatment as income from other sources does not apply where deposited funds are neither amounts payable to members nor other liabilities.

Cash gifts from relatives are not assessable as unexplained cash credits where the recipient establishes donor identity, transaction genuineness and basic creditworthiness. Donor confirmations responding to statutory notices, gift deeds, income-tax returns and financial statements satisfy the initial evidentiary burden. Revenue doubts concerning donors' own sources amount to requiring proof of the source of source and cannot, without independent material, establish that the gifts are the recipient's unexplained money. Comparisons between returned income and gift amounts, or mere suspicion, do not rebut recorded gifts. The gifts were satisfactorily explained, and the addition was deleted.

Reassessment limitation excludes the period allowed for responding to a Section 148A(b) notice when computing the period under the proviso to Section 149(1). Exclusion of the notice-reply period brought the reassessment notice within the applicable three-year period, making approval by the PCIT competent under Section 151(i). A political-party donation is not deductible under Section 80GGC merely because it was paid through banking channels and supported by a receipt. Investigation material showing funds routed through intermediaries and returned to donors established an accommodation-entry arrangement; absent credible rebuttal, the claimed deduction was unsustainable.

Section 80-IA(4) allows infrastructure-facility deductions for enterprises that develop, operate and maintain, or develop and operate qualifying facilities, subject to statutory conditions. EPC contractor status alone does not preclude developer eligibility; the substance of contractual responsibilities and activities governs. Responsibility for design, procurement, execution, testing, commissioning, maintenance, project risks, and deployment of technical and financial resources supports developer status. Where substantially identical claims were accepted in earlier years and no material factual or legal change exists, the deduction remains available and disallowance is deleted.

Clerical omission of income-from-other-sources particulars from a return schedule does not justify an unexplained-money addition where that income was included in taxable income and the related liability was paid through advance tax, tax deduction and self-assessment tax. Consistent disclosures in preceding and succeeding years support treatment of the omission as inadvertent. Directions allowing a Tribunal challenge without applying limitation, while excluding the pendency period of related proceedings, rendered the appeal maintainable when filed immediately after receipt of the relevant order. The unexplained-money addition was consequently set aside.

Cost of improvement in computing capital gains must be attributable to the capital asset or ownership interest transferred. Where jointly owned land is improved but an assessee transfers only a one-tenth interest, expenditure cannot be deducted in full merely because the assessee incurred it or other co-owners made no claim. Without a legally enforceable arrangement or cogent evidence entitling the assessee to set off the entire expenditure against proceeds from the individual share, deduction is restricted to the proportion corresponding to the transferred interest. Accordingly, only one-tenth of the improvement cost is allowable.

Condonation of delay may be warranted where COVID-19 disruption, flood-related relocation, limited staffing and professional default collectively establish sufficient cause. Deduction under section 80P(2)(a)(i) requires examination of annual accounts and identification of income attributable to eligible business activities. Additions for unexplained cash deposits require verification of the assessee's explanation and supporting member KYC particulars after an effective hearing. Quantum and consequential penalty matters require fresh determination on a complete factual record, with penalty consequences dependent on the revised quantum outcome.

Ad hoc disallowance of purchases as business income was unjustified where purchase records, supplier confirmations, bank statements, invoices, stock records and transport evidence supported the transactions. Corresponding purchase and sales quantities, predominantly banking-channel payments, and minimal cash purchases weakened any allegation of bogus purchases. Absence of GST registration or GST numbers on invoices did not support an adverse inference because live bovine animals were GST-exempt. Computer-generated invoices and thumb impressions on cash vouchers, without material proving non-genuineness, were insufficient grounds for disallowance. The purchase disallowance was deleted.

Revision under Section 263 is available where an assessment order is both erroneous and prejudicial to Revenue interests, including where required inquiries or verification were not undertaken. A general request for TDS details and ledger extracts does not establish a conscious examination of substantial commission or brokerage expenditure, the reason for non-deduction of tax, or whether the payment was commission, discount, or another arrangement. Verification may require examination of franchise agreements, invoices, accounting treatment, retention terms, and applicable TDS obligations. Absence of this material inquiry supports setting aside the assessment for fresh examination while leaving ultimate taxability open.

Claimed Form 3CD reporting errors require factual verification against underlying records before a corresponding addition is sustained; the asserted duplication or typographical inflation of an ESI amount therefore remains for Assessing Officer verification. Employee PF/ESI contributions are distinct from employer contributions and are deductible only when deposited within the due dates under the relevant welfare laws. Payment before the income-tax return filing due date does not cure a delay for employee contributions. Accordingly, contributions paid after the statutory due dates are non-deductible for Assessment Year 2020-21.

Penalty proceedings under Section 271AAB require a notice under Section 274 to specify the precise statutory charge, including the applicable clause under Section 271AAB and the related penalty exposure. A notice merely referring to undisclosed income found in a search and proposing penalty under Section 271AAB, without identifying whether clause (a), (b), or (c) applies or stating the relevant conditions, does not provide a meaningful opportunity to respond and breaches natural justice. Such defective notices are invalid; consequently, the associated penalty cannot be sustained.

Unsecured corporate loans supported by lender confirmations, income-tax returns, financial statements and bank records satisfy the assessee's initial Section 68 burden on identity, creditworthiness and genuineness. Additions cannot rest solely on Investigation Wing information or a retracted accommodation-entry statement where no independent lender verification or contrary material exists. A lender's later striking off does not negate loans advanced and repaid when it was active. The second proviso's source-of-source requirement applies only from assessment year 2023-24 and did not govern the years concerned; the loans were satisfactorily explained.
