Substantial expansion treated as new initial assessment year under section 80-IC, allowing fresh 100% profit deduction subject to ten-year cap

SC held that a substantial expansion of an existing manufacturing unit qualifies as a new "initial assessment year" under section 80-IC, entitling the unit to a fresh 100% deduction of profits for the applicable period, subject to the ten-year cap. The Court overruled the contrary approach in Classic Binding, aligned with the reasoning in Mahabir, and emphasized the differing statutory definitions in sections 80-IB and 80-IC. Applied prospectively to qualifying units set up between 7 Jan 2003 and 1 Apr 2012 in Himachal Pradesh, the ruling permits renewal of 100% exemption upon substantial expansion, with the overall deduction periods governed by subsection (6). Decision for the assessee.

Issues Involved:
1. Interpretation of the term "initial assessment year" under Section 80-IC of the Income Tax Act.
2. Eligibility for 100% tax exemption beyond the initial five-year period after substantial expansion of the manufacturing unit.
3. Application of the cap on the total period of deduction under Section 80-IC.

Detailed Analysis:

1. Interpretation of the Term "Initial Assessment Year" under Section 80-IC:
The core issue revolves around the interpretation of the term "initial assessment year" as defined in Section 80-IC(8)(v) of the Income Tax Act. The judgment clarifies that the "initial assessment year" can be the year in which the manufacturing begins, operations commence, or substantial expansion is completed. This definition is crucial as it determines the eligibility for tax exemptions.

2. Eligibility for 100% Tax Exemption Beyond the Initial Five-Year Period After Substantial Expansion:
The judgment addresses whether an assessee can claim 100% tax exemption beyond the initial five years if they have carried out substantial expansion within the ten-year period. The High Court had affirmed that upon substantial expansion, the assessee becomes entitled to claim 100% exemption again from the year of such expansion. The Supreme Court upheld this view, interpreting that substantial expansion triggers a new "initial assessment year," allowing for continued 100% exemption within the overall ten-year cap.

3. Application of the Cap on the Total Period of Deduction Under Section 80-IC:
The judgment also examines the cap on the total period of deduction, which is ten years as per Section 80-IC(6). The Supreme Court clarified that while substantial expansion can reset the "initial assessment year" for the purpose of claiming 100% exemption, the total period of deduction cannot exceed ten years. This means that even with substantial expansion, the total deduction period remains capped at ten years from the first "initial assessment year."

Conclusion:
The Supreme Court concluded that the definition of "initial assessment year" in Section 80-IC allows for multiple initial assessment years within the ten-year period due to substantial expansion. However, the total period of deduction remains capped at ten years. The appeals by the Revenue were dismissed, and the judgment of the High Court was affirmed, allowing the assessees to claim 100% exemption upon substantial expansion within the ten-year period.
