Chapter VIII - Deductions to be Made in Computing Total Income
Section 139
Section 139: profit deduction for a Special Economic Zone Developer
Section 139 is a carry-forward provision. It lets a Developer of a Special Economic Zone (notified on or after 1 April 2005 under the Special Economic Zones Act, 2005) continue claiming the profit deduction it was already entitled to under section 80-IAB of the repealed Income-tax Act, 1961 - but only for the years and amounts that would have been allowed under that old section, calculated exactly as that section prescribed.

Statutory text
Bare law
In respect of any tax year, where—
(a) the gross total income of an assessee, being a Developer, includes any profits and gains derived by an undertaking or an enterprise from any business of developing a Special Economic Zone, notified on or after the 1st April, 2005 under the Special Economic Zones Act, 2005 (28 of 2005) referred to in section 80-IAB of the Income-tax Act, 1961 (43 of 1961); and
(b) such assessee is eligible to claim a deduction from the profits and gains derived from such business for such tax year under the provisions of the said section, as if the said Act had not been repealed,
there shall be allowed, in computing the total income of the assessee, a deduction from the profits and gains derived from such business, subject to the conditions that—
(i) the amount of deduction is calculated as per the provisions of section 80-IAB of the Income-tax Act, 1961 (43 of 1961); and
(ii) the deduction under this Act shall be allowed only for such tax years, as would have been allowed under section 80-IAB of the Income-tax Act, 1961 (43 of 1961), as if the said Act had not been repealed.
Introduction
Section 139 preserves a qualifying SEZ developer deduction that would have been available under Section 80-IAB of the 1961 Act. The project notification, developer status, deduction calculation and remaining eligible years must be tested under that reference.
Key takeaways
Continuing SEZ developer relief
A developer already eligible under Section 80-IAB of the 1961 Act may claim qualifying Special Economic Zone development profits under the 2025 Act.
Old entitlement controls
The amount and eligible tax years remain governed by old Section 80-IAB as if the 1961 Act had not been repealed.
What Section 139 does
Where an assessee, being a Developer, has gross total income that includes profits and gains derived from the business of developing a notified Special Economic Zone as referred to in section 80-IAB of the Income-tax Act, 1961, and the assessee was eligible to claim a deduction under that section (as if it had not been repealed), a deduction from those profits and gains is allowed in computing total income under the 2025 Act.
How the deduction is worked out
The deduction is not recalculated afresh under the new Act - it borrows entirely from the old, repealed provision:
- The amount of the deduction is calculated exactly as per section 80-IAB of the Income-tax Act, 1961.
- The deduction is allowed only for the tax years for which it would have been allowed under section 80-IAB of the Income-tax Act, 1961, as if that Act had not been repealed - i.e. it does not extend or restart the eligibility period.
Historic notification matters
The provision concerns a Developer earning profit from developing a Special Economic Zone within the statutory notification window. Current SEZ status alone does not establish an inherited deduction entitlement.
Step-by-step flow for applying Section 139
- 1
Does gross total income for the tax year include profits and gains derived by an undertaking or enterprise of a Developer from developing a Special Economic Zone notified on or after 1 April 2005?
Section 139(a) looks only at profits and gains from the kind of business referred to in section 80-IAB of the Income-tax Act, 1961, by an assessee that is a Developer.
- No: Section 139 does not apply.
- Yes: Go to the next step.
- 2
Would the assessee be eligible for the section 80-IAB deduction for this tax year, as if the 1961 Act had not been repealed?
Section 139(b) imports the old eligibility test. Section 139 itself sets no fresh conditions, so the historic approvals, commencement facts and claim history must support eligibility.
- Not eligible under the old section: No deduction under this section.
- Eligible: Go to the next step.
- 3
Is this tax year one for which section 80-IAB would still have allowed the deduction?
Condition (ii): the deduction is allowed only for the tax years that would have been allowed under section 80-IAB. Count the years already claimed; the 2025 Act does not restart or extend the period.
- Period already exhausted: No deduction for this or later tax years.
- Year still within the period: Go to the next step.
- 4
Compute the amount as per section 80-IAB and claim it
Condition (i): the amount is calculated as per the provisions of section 80-IAB of the 1961 Act, and is deducted from the profits and gains of that business in computing total income.
Practical checklist
Do
- Keep the SEZ notification, Developer evidence and prior Section 80-IAB claim history.
- Calculate only the remaining tax years and amount allowed by the incorporated 1961 Act rule.
Avoid
- Do not treat this as an open-ended new SEZ deduction.
- Do not blend eligible SEZ development profit with unrelated company income.
Illustrative example
Worked example: an SEZ Developer moving into the 2025 Act
Hypothetical facts (illustration only, not a real taxpayer): A company is the Developer of a Special Economic Zone notified after 1 April 2005 under the Special Economic Zones Act, 2005. It has claimed the section 80-IAB deduction under the 1961 Act. It also earns rent from a commercial property outside the zone.
Developer and notification
The company is a Developer and the zone was notified on or after 1 April 2005, so the profits from developing that zone fall within clause (a). The outside rent is not profit from developing the zone and is kept out.
Old eligibility for this year
Using its notification, Developer records and past claims, it checks that section 80-IAB would still allow the deduction for the tax year (clause (b) and condition (ii)).
Amount
The deduction is computed exactly as section 80-IAB provides (condition (i)) on the zone-development profits only.
Outcome
- If the year is within the remaining old-law period, the deduction is claimed under Section 139 on zone-development profits.
- If the section 80-IAB period has already run out, nothing is available under Section 139, even though the zone continues to operate.
Glossary
- Developer
- The qualifying SEZ developer category used by the provision.
- Inherited eligibility
- The requirement that the 1961 Act deduction would have applied had that Act continued.
Frequently asked questions
Does Section 139 create a new deduction for SEZ Developers?
No. It only continues the deduction a Developer was already entitled to under section 80-IAB of the Income-tax Act, 1961, for whatever remains of that section's original eligibility period, calculated the same way that section prescribed.
Who can claim this deduction?
An assessee that is a "Developer" of a Special Economic Zone notified on or after 1 April 2005 under the Special Economic Zones Act, 2005, and that was eligible for the deduction under section 80-IAB of the Income-tax Act, 1961.
