“Section 57(1)”

The Commissioner cannot revise an assessment under Section 263 merely because the assessment order does not explicitly reflect an inquiry, or because the Commissioner holds a different opinion. An inquiry, even if considered inadequate, or an assessment based on a plausible view by the Assessing Officer after due examination, does not automatically make the order erroneous or prejudicial to the interests of the revenue.

Interest income earned on deposits, particularly before the commencement of business operations or as a requirement for business licensing, is taxable as "income from other sources" under Section 56, and cannot be treated as business income or set off against interest on borrowed funds.

For exercising revisional jurisdiction under Section 263, the Commissioner must first find that the Assessing Officer's order is erroneous and unsustainable in law, as this is a condition precedent. An order is not erroneous merely because two views are possible, or if the Commissioner disagrees with the Assessing Officer's permissible view, or to simply remit the matter for further enquiries.

For deductions under Section 57(iii) relating to "Income from Other Sources," an expenditure is allowable if it is laid out wholly and exclusively for the purpose of making or earning such income, even if no income is actually earned in that previous year.

Interest received under Section 28 of the Land Acquisition Act, 1894, is considered part of the enhanced compensation on compulsory acquisition of land. It is taxable as 'capital gains' and not separately as 'interest income' under the head Income from Other Sources.

Interest earned by a Co-operative Society from investing fixed deposits in banks is entitled to a deduction under Section 80P(2)(a)(i) of the Income-tax Act.

Corporate guarantee fees are subject to transfer pricing rules, and adjustments may be needed to account for differences between corporate guarantees and more liquid bank guarantees when determining arm's length price.

For computing the deduction under Section 80M, only the net dividend income (gross dividend income after reducing expenses attributable to earning it, as per Section 57(iii) and the principle in Section 80AB) is eligible. The case also holds that tax authorities are not bound to perpetuate an error from a previous assessment year, as each year is a separate unit and consistency cannot override substantive justice.
