Assessment validity turns on timely determination of tax payable; unsigned Form I.T. 30 alone does not invalidate it.

For completion of assessment under the Income-tax Act, the statutory requirement is that the Income-tax Officer determine the assessee's total income and the tax payable within the limitation period under section 153. The absence of the officer's signature on Form I.T. 30 is not, by itself, a mandatory statutory defect and does not invalidate the assessment. The decisive question is whether the tax payable was actually determined within time. The Tribunal was found to have proceeded only on the unsigned form without first examining that issue, and the matter was remanded for that factual determination.

Issues: Whether the Income-tax Officer was required, for completion of assessment under the Income-tax Act, 1961, to sign Form I.T. 30 and whether absence of such signature invalidated the assessment as time-barred.

Analysis: Under section 143(3), assessment is completed when the Income-tax Officer, after hearing the assessee and considering the material, determines the total income and the sum payable. Section 153 fixes the time within which the assessment order must be made. The Court found no statutory requirement in the Act or the Rules that Form I.T. 30 must be signed by the Income-tax Officer as a condition precedent to a valid assessment. The Tribunal had proceeded on the sole basis that the form was unsigned, without first examining whether the tax payable had in fact been determined within the statutory time-limit.

Conclusion: No, signing of Form I.T. 30 by the Income-tax Officer was not a mandatory statutory requirement for completion of the assessment. The matter was remanded to the Tribunal to decide whether there had been an actual determination of tax payable within the time prescribed by section 153.

Ratio Decidendi: For completing an assessment under section 143(3), the statutory requirement is determination of total income and tax payable within the limitation period; absence of the Income-tax Officer's signature on Form I.T. 30, by itself, does not invalidate the assessment.
