What is Section 80-IC of the Income-tax Act?
Section 80-IC, under Chapter VI-A, provides a deduction for specified profits and gains derived by qualifying manufacturing undertakings or enterprises in certain special-category states. The benefit applies only to businesses meeting the commencement or substantial-expansion windows, prescribed location or product conditions, and other safeguards. It is not a general deduction available merely because a business is located in a hill state.
Under section 80-IC(1), profits from a business described in sub-section (2) qualify for deduction at the rates in sub-section (3), subject to the rest of the section. The deduction is calculated on eligible business profits, not on the enterprise's entire turnover.
Eligible states, activities and historical commencement periods
Section 80-IC(2) covers two principal routes: clause (a), manufacture or production of articles other than those in the Thirteenth Schedule at specified notified industrial locations; and clause (b), manufacture or production of items, or performance of operations, listed in the Fourteenth Schedule in the relevant state. The law also addressed qualifying substantial expansion of existing undertakings within the relevant period.
| Location | Relevant historical period under section 80-IC(2) | Location / product test |
|---|---|---|
| Sikkim | 23 December 2002 to 31 March 2007 | Notified areas for clause (a); specified Fourteenth Schedule activities for clause (b) |
| Himachal Pradesh and Uttarakhand (formerly Uttaranchal) | 7 January 2003 to 31 March 2012 | Notified areas for clause (a); specified Fourteenth Schedule activities for clause (b) |
| North-Eastern States covered by section 80-IC | 24 December 1997 to 31 March 2007 | Notified areas for clause (a); specified Fourteenth Schedule activities for clause (b) |
For this provision, the statutory definition of North-Eastern States lists Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland and Tripura. Sikkim is addressed separately. The above dates are historical entry conditions, not fresh eligibility periods in 2026.
Section 80-IC(3): deduction amount and duration
| Eligible undertaking | Deduction | Maximum period |
|---|---|---|
| Sikkim and qualifying North-Eastern States | 100% of eligible profits and gains | 10 assessment years beginning with the initial assessment year |
| Himachal Pradesh and Uttarakhand | 100% of eligible profits for first 5 assessment years; 25% for the next 5 (30% where the assessee is a company) | 10 assessment years in total, subject to statutory conditions |
Important: Substantial expansion does not automatically restart the ten-year deduction period or entitle a Himachal Pradesh or Uttarakhand undertaking to a second five-year period at 100%. The Supreme Court addressed this issue in PCIT v. Aarham Softronics (2019); the initial-year and overall ten-year limits must be applied in light of the facts and the governing law.
Section 80-IC(4) to (7): essential conditions and restrictions
Formation and machinery conditions: section 80-IC(4)
- The undertaking must not ordinarily be formed by splitting up or reconstructing an existing business, subject to the statutory exception linked to section 33B.
- It must not ordinarily be formed by transferring previously used machinery or plant to a new business. The exceptions and 20% tolerance in the explanations to section 80-IA(3) apply.
- For the specified-location route, the industrial estate, industrial area, industrial park, growth centre, software technology park or other prescribed location must meet the relevant notification requirements.
No duplicate deduction: section 80-IC(5)
Where deduction is claimed under section 80-IC, the same profits cannot also support a deduction under another provision of Chapter VI-A or under the historical sections 10A or 10B. This prevents overlapping incentives on identical eligible profits.
Overall ten-year ceiling: section 80-IC(6)
The aggregate deduction period under section 80-IC and specified predecessor benefits, including the relevant second proviso to section 80-IB(4) and section 10C, cannot exceed ten assessment years.
Application of section 80-IA: section 80-IC(7)
Section 80-IA(5) and sections 80-IA(7) to (12) apply, as far as relevant. These include separate computation of eligible-business profits, audit certification, market-value treatment of internal transfers, restrictions on duplicate benefits and adjustments for non-arm's-length arrangements.
Definitions under section 80-IC(8)
- Initial assessment year: The assessment year corresponding to the previous year in which the undertaking begins manufacture or production, starts the eligible operation, or completes qualifying substantial expansion, read with the overall deduction-period restrictions.
- Substantial expansion: An increase in investment in plant and machinery of at least 50% of its book value, before depreciation in any year, measured as on the first day of the previous year in which expansion is undertaken.
- Industrial area, industrial estate, industrial growth centre, industrial park and integrated infrastructure development centre: The respective places notified by the Central Board of Direct Taxes under the applicable central-government scheme.
- Software technology park: A park set up in accordance with the Government of India's Software Technology Park Scheme.

- Fourteenth Schedule: The statutory schedule identifying qualifying articles, things or operations for the alternative route under section 80-IC(2)(b).
How an eligible undertaking claims the deduction
- Verify the original date of commencement or qualifying expansion and the applicable statutory window.
- Retain location notifications, industrial approvals, production records, fixed-asset registers and documents evidencing substantial expansion, where relevant.
- Compute profits attributable to the eligible undertaking separately, including the section 80-IA(5) and market-value adjustments.
- Obtain the prescribed accountant's audit report, generally Form 10CCB for claims governed by the 1961 Act, and comply with the applicable electronic filing rules and due dates.
- Check section 80AC, which conditions the specified profit-linked deductions on timely return filing for applicable assessment years, and confirm that the chosen tax regime permits the deduction.
