Section 37(1) of the Income Tax Act

Where an assessee claims that investments were made out of own funds, interest disallowance under Section 14A read with Rule 8D may not apply if the assessee demonstrates the availability of sufficient interest-free funds to cover such investments.

An assessee cannot raise a new claim or a claim not made in the original or revised return of income for the first time directly before the Assessing Officer during assessment proceedings.

The principle of consistency applies in tax matters, meaning a fundamental aspect found to be true in one assessment year should not be changed in a subsequent year if the order was not challenged.

Disallowance under Section 14A is not automatic and requires the Assessing Officer to record satisfaction before applying Rule 8D. Only investments yielding exempt income are considered for disallowance, irrespective of their strategic nature.

A disallowance under Section 14A of the Income-tax Act, 1961, for expenditure incurred in relation to exempt income cannot be made if the assessee has not earned any exempt income during the relevant previous year.

Employee contributions to provident fund and ESI deposited by an employer beyond the due dates prescribed under the respective special Acts are not allowable as a deduction under section 36(1)(va) of the Income-tax Act, 1961. Such disallowance can be made during processing under section 143(1).

When an assessee possesses interest-free funds sufficient to cover investments yielding tax-free income, it is presumed that such investments were made from these interest-free funds, precluding disallowance of interest expenditure under Section 14A.

Rule 8D, for computing disallowance under Section 14A for expenses related to exempt income, applies from Assessment Year 2008-09 onwards; for prior years, a reasonable disallowance must be made. The disallowance under Section 14A cannot exceed the actual exempt income earned.

Foreign exchange fluctuations, whether gains or losses, are inextricably linked to the underlying business transaction and must be accounted for under the mercantile system. The Supreme Court also affirmed the standard accounting principle of valuing stock at cost or net realisable value, whichever is lower.

When an income or expenditure is revenue neutral across different assessment years, where any benefit derived is offset by a corresponding liability or reversal, no additional tax liability arises, particularly concerning income recognition under the mercantile system of accounting.
