Retrospective tax amendments and Indian State business losses could not reduce taxable business income for the year in issue.

The proviso to Section 24(1) did not apply to assessment year 1944-45 because the assessment was governed by the law in force on 1 April 1944 and the amendment could not operate retrospectively. Losses from business carried on in Indian States were outside the taxable computation under Section 10 read with Section 14(2)(c), so they could not be set off against taxable British India business profits. The assessee's business income was therefore computed without allowing the Indian State business loss, and the tax computation was sustained.

Issues: (i) Whether the proviso to Section 24(1) of the Indian Income-tax Act applied to the assessment year 1944-45. (ii) Whether the loss suffered in business carried on in Indian States was to be ignored in computing the assessee's business income for the previous year relevant to assessment year 1944-45.

Issue (i): Whether the proviso to Section 24(1) of the Indian Income-tax Act applied to the assessment year 1944-45.

Analysis: The relevant accounting year ended before the proviso came into force. The assessment was governed by the law in force on the first day of the assessment year, and the amended provision could not be applied retrospectively to that assessment. The applicable statutory framework under the Finance Act of 1944 incorporated the law as it stood on 1 April 1944.

Conclusion: The proviso to Section 24(1) did not apply to assessment year 1944-45.

Issue (ii): Whether the loss suffered in business carried on in Indian States was to be ignored in computing the assessee's business income for the previous year relevant to assessment year 1944-45.

Analysis: Section 24(1) dealt with set-off between different heads of income and did not assist where both income and loss arose under the same head of business. Under Section 10 read with Section 14(2)(c), income accruing in an Indian State was outside the charge unless brought within the taxing provisions, and losses from such exempt business could not be used to reduce taxable business profits from British India. The computation had therefore to proceed on the taxable business income alone.

Conclusion: The loss of Rs. 25,391 from the Indian State business was to be ignored in determining the assessee's business income.

Final Conclusion: The questions referred were answered so as to sustain the tax computation against the assessee, and the reference was disposed of accordingly.

Ratio Decidendi: A loss from business carried on in an Indian State, being outside the taxable computation under the governing provisions, cannot be deducted from taxable British India business profits, and an amendment not in force during the relevant assessment period does not apply retrospectively.
