Rectification for apparent error and limitation under section 154: original assessment date governs, not a later reassessment.

Rectification under section 154 is available where an original allowance, such as deduction of wealth-tax from business income, is contrary to the settled legal position and therefore constitutes a mistake apparent from the record. The limitation period under section 154(7) runs from the date of the original assessment order sought to be amended, not from a later reassessment order under section 147(b). A reassessment confined to escaped income does not automatically efface or fully merge the original assessment for all purposes. The discussion concludes that rectification may be valid in principle, while a notice issued beyond four years from the original assessment is time-barred.

Issues: (i) Whether the deduction of wealth-tax from business income constituted a mistake apparent from the record rectifiable under section 154 of the Income-tax Act, 1961. (ii) Whether the rectification notice for assessment year 1959-60 was barred by limitation under section 154(7) of the Income-tax Act, 1961.

Issue (i): Whether the deduction of wealth-tax from business income constituted a mistake apparent from the record rectifiable under section 154 of the Income-tax Act, 1961.

Analysis: The deduction of wealth-tax had been allowed in the original assessments, but the legal position had already been authoritatively declared that such tax was not an allowable deduction in computing business income. Once the governing legal position was clear, the erroneous deduction became a mistake apparent from the record and was capable of rectification under section 154.

Conclusion: The answer was in the affirmative, and the issue was decided against the assessee.

Issue (ii): Whether the rectification notice for assessment year 1959-60 was barred by limitation under section 154(7) of the Income-tax Act, 1961.

Analysis: The period of four years had to be computed from the date of the original assessment order sought to be amended, not from the date of a later reassessment order under section 147(b). A reassessment under section 147(b) does not make the original assessment order cease to exist for all purposes or merge it completely, and the rectification power cannot be extended by reference to the later reassessment where the error was not the subject of that later order.

Conclusion: The answer was in the negative, and the issue was decided in favour of the assessee.

Final Conclusion: The rectification was sustainable in principle, but the proceedings for assessment year 1959-60 were time-barred, so the overall outcome was only partly in favour of the assessee.

Ratio Decidendi: For rectification under section 154, the limitation period runs from the date of the order sought to be amended, and a reassessment confined to escaped income does not automatically efface or merge the original assessment order for all purposes.
