Section 143(2) of the Income Tax Act

Appellate authorities can consider new claims and additional grounds if the relevant facts are already on record. The purpose of assessment is to correctly determine tax liability, allowing both parties to raise issues.

In a search assessment under Section 153A, additions can only be made for completed or non-abated assessment years if incriminating material relevant to those years is found during the search, although notice under Section 153A(1) is mandatorily issued for six assessment years preceding the search.

For revision under Section 263, the Assessing Officer's order must be both erroneous and prejudicial to the interests of the revenue; if either condition is not met, the revisionary jurisdiction cannot be invoked. An order is not erroneous merely because the Assessing Officer did not record the details of enquiries conducted, provided due enquiries were made.

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.

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.

An Assessing Officer cannot initiate reassessment proceedings under Section 147 of the Income Tax Act based on a mere change of opinion. Reassessment is permissible only when there is fresh tangible material leading to the belief of income escapement, not merely a review of existing facts.

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.

Taxing statutes are presumed to operate prospectively unless a clear contrary intention for retrospective application is evident. The law applicable for determining tax liability is that which stands on the first day of the assessment year, following the principle that law looks forward, not backward (lex prospicit non respicit).

Additions for alleged bogus purchases should be restricted to the profit element, not the entire turnover. The profit element is often estimated at 12.5% of the purported bogus purchases.
