POONA ELECTRIC SUPPLY CO. LTD. vs COMMISSIONER OF INCOME-TAX, BOMBAY

The Supreme Court held that under Section 10(1) of the Income Tax Act, 1922, the real profit of a business must be determined based on commercial principles, which necessitates the exclusion of amounts transferred to the 'Consumers Benefit Reserve Account' as these represent rebates to consumers. The Court clarified that there is a distinction between commercial profits and statutory profits, emphasizing that deductions for tax purposes must reflect real income, which cannot include amounts statutorily mandated for consumer rebates. The High Court's ruling against the assessee was overturned, allowing the deductions claimed by the appellant.
