Exemption-notification amendments operate prospectively unless they expressly provide for retrospective effect. Where bills of lading pre-date an amendment, it cannot govern those imports or justify refusing consideration of provisional release under Section 110A of the Customs Act, 1962. Provisional release must be assessed under the law applicable on the relevant import dates and granted upon compliance with conditions lawfully imposed under that provision.

Exemption-notification amendments operate prospectively unless they expressly provide otherwise. An amendment commencing after the bill of lading cannot govern imports covered by that earlier bill or be used to refuse consideration of provisional release under the Customs Act. Requests for provisional release must instead be considered under applicable law, with release available subject to imposed conditions.

Board instructions under section 131BA regulate departmental appeals before CESTAT through prescribed monetary thresholds. Appeals with tax effect below the applicable limit may be withdrawn, including pending appeals. Low tax effect constitutes a basis for treating a departmental appeal as non-maintainable. The framework concerns the Board's power to issue instructions governing the institution and continuation of departmental appeals.

Pecuniary jurisdiction for scrutiny proceedings rests with the ITO where returned income falls below the prescribed threshold under the applicable CBDT instruction. A notice under Section 143(2) issued by an ACIT without allocated pecuniary jurisdiction is invalid where no prior transfer of jurisdiction has been made under Section 127. Subsequent completion of the assessment by the ITO does not cure the defect in initiating scrutiny proceedings. The consequential assessment lacks legal validity because it derives from an invalid jurisdictional notice.

Salary earned by a Vietnam tax resident for employment exercised wholly in Vietnam accrued where the services were performed and was taxable in Vietnam. Under the India-Vietnam DTAA, read with section 90, employment remuneration is governed by the treaty residence and employment provisions. Sections 5(2), 9(1) and 15(1)(a) treat the place of performance as determinative of salary accrual. Payment through an Indian payroll, credit to an Indian bank account, and Indian tax withholding do not by themselves make that foreign employment income taxable in India.

Section 69C does not support an unexplained-expenditure or ad hoc profit addition where recorded purchases, banking payments and corresponding sales are supported by invoices, ledgers, GST material and e-way bills, absent specific accounting defects or evidence of additional profit. Enhancement under section 69A requires prior reasonable opportunity under section 251(2) and evidence that the taxpayer owned unrecorded money or assets. Unauthenticated WhatsApp material from an employee's device, without corroboration, and rebuttable search presumptions do not by themselves establish such ownership. Staff welfare, worker accommodation and vehicle expenditure qualify under section 37 when evidence shows a wholly and exclusively business purpose and no identified personal use.

Pendency of registration proceedings does not render an appeal against denial of exemption in an income-tax intimation infructuous. The jurisdiction to grant registration and the appellate jurisdiction over denial of an exemption claim are separate statutory jurisdictions. Pending registration may affect eventual eligibility, but it does not extinguish the statutory appeal. Exemption eligibility must be determined for the relevant assessment year by reference to the registration status ultimately obtained and fulfilment of applicable statutory conditions.

Delayed realization of receivables from associated enterprises may constitute a separately benchmarkable international transaction because deferred payments, receivables and business debts fall within that scope. Working capital adjustment, calculated from opening and closing receivable and payable balances, does not automatically capture invoice-specific delays beyond agreed credit periods. However, a notional-interest transfer-pricing adjustment is unwarranted where the taxpayer is debt-free and there is no evidence of interest cost, reduced profitability, or a financing benefit conferred on an associated enterprise. Delayed recovery alone does not establish an arm's length financing charge in those circumstances.

Rule 17A(2) distinguishes institutions created under an instrument from those created otherwise. For institutions created without a formal instrument, documents evidencing their creation or establishment are required, while registration with the Registrar of Public Trusts is independently recognised. Requiring a trust deed or memorandum in every instance would make the separate requirement for establishment documents ineffective. Public-trust registration alone does not establish eligibility for renewal; objects, activities and statutory compliance must also be examined for section 12AB satisfaction. Renewal cannot be refused solely because no formal trust deed or memorandum is produced.

The notified 3% transfer-pricing tolerance under Rule 10CA(7) applies where an arm's-length benchmark uses a single internal comparable, because its arithmetical mean is that single value; the vehicle-segment adjustment falls where the declared margin remains within the band. Corporate guarantee pricing must reflect its distinction from a bank guarantee, with the stated benchmark of 0.5%. A separate notional-interest adjustment on overdue associated-enterprise receivables requires verification that interest was likewise not charged to comparable third-party export customers; no adjustment arises if that uniform practice is substantiated.

Alleged bogus purchases in a wholesale industrial-chemicals business need not be disallowed in full under Section 69C where procurement from unregistered dealers remains possible and corresponding sales are undisputed. The appropriate adjustment is confined to estimating the profit element embedded in unverified purchases. A lump-sum gross-profit disallowance of 5% was retained, while the remaining addition was deleted.

Section 69C permits addition only where expenditure remains unexplained; accepted sales, undisputed trading results, purchase invoices, GST returns and stock records weighed against treating all purchases as bogus. Missing transport documents, e-way bills and delivery challans prevented full acceptance, warranting a limited purchase adjustment rather than disallowance of the entire claimed amount, including GST. The addition for a discrepancy in income from other sources was deleted because the record and submissions did not support it.

Faceless reassessment under Section 147 may be transferred on a case-by-case basis from NFAC to the Jurisdictional Assessing Officer, who may validly complete it; the draft-order procedure under Section 144B does not apply where that officer completes the reassessment. A deduction for political contributions may be disallowed where investigation material, banking trail and the recipient political party's identified modus operandi support disallowance. Detailed bank narration of receipts and repayments can explain disputed credits and preclude treatment as unexplained money. Ledger evidence of ELSS mutual-fund investment supports a claimed Section 80C deduction.

Rule 46A permits admission of material additional evidence on creditor balances, subject to verification before determining unexplained cash-credit additions. Agricultural income exemption requires proof of agricultural land, operations, receipts and related expenditure; absent adequate particulars, the character of the income requires factual verification. Rebate and discount claims require verification of confirmations and underlying transactions. Whether a reduction in share application money constitutes a refund or a transfer depends on whether shares were allotted, affecting capital-gain treatment. Estimated agricultural expenditure must address explanations regarding prior plantation costs and current maintenance spending. Unsupported agricultural expenditure requires sale bills, evidence of agricultural land use and expense vouchers.

Where scrutiny notice under Section 143(2) precedes processing of the return under Section 143(1), parallel summary processing under Section 143(1) is not valid. Assessment must proceed under Section 143(3), rather than adopt a prima facie adjustment made through a subsequent intimation. An assessment founded on such an invalid intimation lacks a sustainable basis; consequently, the Section 143(1) intimation was quashed and the consequential Section 143(3) assessment was set aside.

Transfer-pricing benchmarking requires separate evaluation of sub-contract and support-service transactions where separate agreements, functional profiles, risk allocation and audited segmental accounts show they are not closely linked. Support services rendered to an associated enterprise on a cost-plus, limited-risk basis differ from end-to-end sub-contract performance for third-party customers involving market and service-delivery risks; aggregation is therefore inappropriate. Notional interest on outstanding receivables is not sustainable where the entity is debt-free, has interest-free advances from its associated enterprise, holds net payables, and has not used borrowed funds to extend credit.

Penalty under section 271AAB(1) requires a recorded finding that surrendered income falls within the statutory definition of undisclosed income; a search disclosure alone does not satisfy that requirement. The particular clause and default invoked must be specified in the penalty notice and proceedings, and failure to identify the charge invalidates the penalty process. Where the assessment is appealed, penalty proceedings must be completed within six months of receipt of the appellate order; completion beyond that period is time-barred. These independent defects render the penalty legally unsustainable.

Extrapolation of alleged unaccounted sales from seized loose sheets covering only 41 days and WhatsApp communications relating to a different period requires independent incriminating evidence of similar unrecorded sales during the relevant assessment year. Material dated from 30 December 2021 to 9 February 2022 did not establish continuous unaccounted sales in FY 2020-21. Estimating annual unaccounted sales for AY 2021-22 solely by extending that limited-period material lacked evidentiary support; the estimated addition was therefore unsustainable and its deletion was affirmed.

Reassessment notices issued beyond three years require escaped income in the prescribed form to meet the statutory threshold under Section 149(1)(b). Cumulative expenditure may support assessment-year-wise notices under Section 149(1A) only where it relates to the same event or occasion across multiple previous years. Cash payments connected with distinct quotations or orders, made on different dates for different items, constitute separate events and cannot be aggregated to satisfy that threshold. Third-party seized material did not alter the limitation position where the relevant assessment year lay outside the applicable ten-year search-assessment block. The notices were therefore barred by limitation and quashed.

Section 153C requires the jurisdictional Assessing Officer of the other person to independently examine seized material and record satisfaction that it is relevant to determining that person's total income for the relevant assessment year. Reproducing information received from the Assessing Officer of the searched person and merely describing the matter as fit for notice does not meet this mandatory condition. Where the satisfaction record does not identify how the seized material affects the assessee's total income for the impugned year, initiation of Section 153C proceedings lacks valid jurisdiction.
