Section 139 Income Tax Act 2025: Can SEZ Developers Claim Profit Deduction?

Section 139 of the Income-tax Act, 2025 continues the profit-linked deduction for eligible developers of Special Economic Zones (SEZs), subject to the conditions and remaining deduction period under the former Section 80-IAB of the Income-tax Act, 1961.

What does Section 139 provide?

Section 139, located in Chapter VIII (deductions to be made in computing total income), addresses profits and gains from the business of developing a Special Economic Zone. It operates as a continuation provision: eligibility and the amount of deduction depend on Section 80-IAB of the Income-tax Act, 1961, applied as though that Act had not been repealed.

It does not create a fresh deduction period for a developer merely because the Income-tax Act, 2025 has commenced. Only tax years that would have qualified under Section 80-IAB remain eligible.

Eligibility and statutory conditions

  1. Developer status: The assessee must be a Developer whose gross total income includes profits and gains derived by an undertaking or enterprise from developing a Special Economic Zone.
  2. Notified SEZ: The zone must have been notified on or after 1 April 2005 under the Special Economic Zones Act, 2005 and be of the kind referred to in former Section 80-IAB.
  3. Continuing eligibility: The assessee must remain eligible for the relevant tax year under Section 80-IAB, treating the Income-tax Act, 1961 as though it had not been repealed.
  4. Calculation: The deduction must be calculated in accordance with the former Section 80-IAB.
  5. Remaining years: The deduction is allowed only for those tax years for which it would have been available under Section 80-IAB.
Practical effect: Section 139 is not a new incentive for all newly established SEZ developers. The historical commencement date, approval or notification, qualifying activity, and remaining deduction years must be examined.

Relevant statutory definitions

Special Economic Zone (SEZ): A specially designated area governed by the Special Economic Zones Act, 2005. Its statutory meaning and notification status must be checked under that Act.
Developer: The term is used in the context of the Special Economic Zones Act, 2005 and generally concerns a person granted the required approval for developing an SEZ, including persons treated as developers under that legislation.
Gross total income: Income computed before deductions under the applicable chapter for deductions, subject to the Act's computation provisions.
Profits and gains derived from developing an SEZ: Qualifying business profits attributable to the development activity; other receipts are not automatically eligible merely because they arise in an SEZ-related business.
Tax year: The annual period used for computing income under the Income-tax Act, 2025, replacing the previous-year and assessment-year framework for years governed by the new Act.

How is the deduction calculated?

The amount and applicable period must be determined using the substantive rules of former Section 80-IAB, including its historical conditions. Broadly, that section provided a deduction of 100% of eligible profits for ten consecutive assessment years out of fifteen years beginning with the year of notification, subject to the requirements of that section. Section 139 preserves only the entitlement that continues to exist under those rules.

The developer should verify the SEZ notification, the year from which the deduction was first claimed, the remaining qualifying years, and the eligible profit computation. Any applicable audit, return-filing, anti-duplication, or other general deduction conditions must also be considered.

Illustrative example

Assume a qualifying SEZ developer has eligible development profits of Rs 2 crore in tax year 2026-27 and that the same year falls within the developer's unexpired, valid deduction period under former Section 80-IAB. Subject to the statutory conditions and computation rules, the developer may claim the deduction in computing total income under Section 139.

Conversely, if the permitted deduction period has already ended, Section 139 does not restart it. A developer cannot claim a new ten-year window solely because the law was reenacted.

Frequently asked questions

Does Section 139 apply to every SEZ unit?

No. This provision addresses eligible developers of Special Economic Zones. Deductions for SEZ units carrying on other eligible activities are governed by different provisions.

Is Section 139 the same as return filing under the old Act?

No. Return filing was addressed by Section 139 of the Income-tax Act, 1961. Section 139 of the Income-tax Act, 2025 concerns qualifying SEZ developer profits.

Can a developer claim a fresh deduction period from 2026?

No. The deduction continues only for tax years that would have been eligible under Section 80-IAB of the earlier Act.

What records should a developer retain?

Relevant records include the SEZ notification, developer approvals, financial statements, eligible-profit working papers, prior deduction claims, and supporting audit or tax documents as applicable.
