Filing Form-10 is mandatory before original assessment; allowed during re-assessment but not before Tribunal.

The court ruled that the filing of Form-10 under Section 11 of the Income Tax Act, 1961, is mandatory before the completion of the original assessment proceedings. The SC held that failure to submit Form-10 before the original assessment precludes the exclusion of income from taxation. However, during re-assessment proceedings initiated by the revenue, the assessee is permitted to file Form-10. The judgment favored the appellant for re-assessment years, allowing Form-10 submission during those proceedings, but ruled against the appellant where Form-10 was filed only before the Tribunal.

Issues Involved:
- Interpretation of the requirement to furnish Form-10 under Section 11 of the Income Tax Act, 1961 during re-assessment proceedings.
- Whether the assessing authority must have the information under Form-10 at the time of completing the assessment.

Analysis:

Issue 1: Interpretation of Form-10 Requirement
The case involved a dispute regarding the filing of Form-10 under Rule 17 of the Income Tax Rules, 1962 during re-assessment proceedings. The appellant argued that the Form-10 was filed during the re-assessment proceedings initiated under Section 147 of the Income Tax Act for certain assessment years. The revenue contended that the Form-10 could only be produced until the completion of the original assessment proceedings under Section 143(3) and not during re-assessment. The key question was whether the filing of Form-10 during re-assessment proceedings was permissible under the law.

Issue 2: Timing of Form-10 Submission
The Supreme Court's decision in CIT Vs. Nagpur Hotel Owners Association was cited, emphasizing the mandatory nature of providing information under Form-10 to the assessing authority before completing the assessment. The Court highlighted that without the necessary information in Form-10, the assessing authority could not exclude income from taxation under Section 11. It was noted that any claim for the benefit of Section 11 based on post-assessment information would require reopening of the assessment, which the Act did not allow. The Court clarified that compliance with the Form-10 requirement had to be before the completion of assessment proceedings.

Issue 3: Impact on Assessment
The Court reiterated that once the assessment was completed without the required information in Form-10, fault could not be found with the assessing authority for including the income in the assessable amount. It was emphasized that the Act did not permit reopening of assessments for claims based on information provided after the assessment was finalized.

Issue 4: Decision on Form-10 Filing During Re-Assessment
The Court concluded that while an assessee could not request assessment reopening for failing to furnish Form-10 during the original assessment, during re-assessment proceedings initiated by the revenue, the assessee could still provide Form-10. The judgment favored the appellant for appeals related to re-assessment years, allowing the filing of Form-10 during those proceedings. However, for the appeal where Form-10 was submitted only before the Tribunal, the decision went against the appellant.

In summary, the judgment clarified the timing and significance of filing Form-10 under Section 11 of the Income Tax Act, emphasizing the necessity of providing the required information before the completion of assessment proceedings. It highlighted the implications of not furnishing Form-10 on income exclusion and the limitations on claiming benefits post-assessment. The decision differentiated between original assessment and re-assessment scenarios, allowing the filing of Form-10 during re-assessment proceedings initiated by the revenue.
