Section 80IBA: 100% Tax Deduction for Affordable Housing Developers
Section 80IBA of the Income Tax Act, 1961 allows real estate developers to claim a 100% deduction on profits earned from developing and building affordable housing projects. Introduced by the Finance Act 2016, effective from April 1, 2017, this provision was created to support the Government of India’s Housing for All objective under the Pradhan Mantri Awas Yojana.
This deduction is available only under the old tax regime and applies exclusively to developers and builders, not to individual home buyers. If you are a builder or developer with a project approved on or before March 31, 2022, this guide explains every condition you must satisfy, what the sunset clause means for your project, and how the deduction is calculated and claimed.
What Section 80IBA Offers
Under Section 80IBA(1), where the gross total income of an assessee includes any profits and gains derived from the business of developing and building housing projects, a deduction of an amount equal to 100% of the profits and gains derived from such business is allowed, subject to the conditions prescribed in the section.
This means the entire profit from an eligible affordable housing project is excluded from taxable income for that assessment year. The deduction is applied while computing total income under Chapter VI-A. It can reduce total income to the extent of gross total income but cannot create a loss.
Who Can Claim Section 80IBA
Section 80IBA is available to any assessee whose gross total income includes profits from the business of developing and building housing projects. This includes:
- Individual builders and developers
- Companies engaged in real estate development
- Partnership firms and LLPs involved in housing project development
- Hindu Undivided Families (HUFs) earning business profits from housing projects
The assessee must be in the business of developing and building the housing project. A landowner who merely transfers land for development cannot claim this deduction. The deduction is also not available to an assessee carrying out the project under a works contract arrangement.
The Sunset Clause: Approval Deadline is March 31, 2022
The approval deadline under Section 80IBA has been extended multiple times since the section was introduced. The final deadline, after extensions in Budget 2018, Budget 2020, and Budget 2021, is March 31, 2022. No extension was announced in Budget 2023, Budget 2024, or Budget 2025.
| Amendment | Approval Deadline |
|---|---|
| Finance Act 2016 (original) | March 31, 2019 |
| Budget 2018 | March 31, 2020 |
| Budget 2020 | March 31, 2021 |
| Budget 2021 | March 31, 2022 |
| Current status | No further extension |
No new projects approved after March 31, 2022 are eligible for this deduction. Projects approved on or before March 31, 2022 can continue to claim the deduction in subsequent assessment years until the project is completed, provided all prescribed conditions continue to be met.
Position under Income Tax Act 2025: Clause 142 of the Income Tax Act 2025, effective from April 1, 2026, preserves the deduction for eligible projects through a transitional provision. Assessees who qualified under Section 80IBA of the old Act may continue to claim deductions computed under the prior statute for the tax years that would have been covered, subject to the same substantive conditions including project approval, completion requirements, unit size thresholds, separate project accounts, and the clawback mechanism. No new projects are eligible under the new Act. For more on how the Income Tax Act 2025 handles transitional provisions, see Income Tax Act 2025 vs Income Tax Act 1961.
Conditions to Satisfy Under Section 80IBA
All the following conditions must be satisfied simultaneously. Failure to meet even one condition disqualifies the project from the deduction for that assessment year.
1. Project Approval Date
The project must be approved by the competent authority on or after June 1, 2016 and on or before March 31, 2022. Where approval for the same housing project is obtained more than once, the project is deemed approved on the date on which the building plan was first approved by the competent authority.
2. Project Completion Timeline
The project must be completed within five years from the date of approval by the competent authority The project is deemed completed when a certificate of completion for the project as a whole is obtained in writing from the competent authority.
Clawback provision: If the project is not completed within this period, the entire amount of deduction claimed in earlier assessment years is treated as income of the previous year in which the five-year period expires and taxed accordingly.
3. Minimum Plot Size
The project must be on a plot of land measuring not less than:
- 1,000 square metres where the project is located within the metropolitan cities of Bengaluru, Chennai, Delhi NCR (limited to Delhi, Noida, Greater Noida, Ghaziabad, Gurugram, Faridabad), Hyderabad, Kolkata and Mumbai (whole of Mumbai Metropolitan Region)
- 2,000 square metres where the project is located in any other place
4. Residential Unit Carpet Area Limit
The carpet area of each residential unit in the project must not exceed:
- 60 square metres where the project is located within the metropolitan cities of Bengaluru, Chennai, Delhi NCR (limited to Delhi, Noida, Greater Noida, Ghaziabad, Gurugram, Faridabad), Hyderabad, Kolkata and Mumbai (whole of Mumbai Metropolitan Region)
- 90 square metres where the project is located in any other place
This condition applies at the individual unit level. If even one residential unit in the project exceeds the prescribed carpet area limit, the deduction is unavailable for the entire project.
5. Stamp Duty Value of Residential Units
For projects approved on or after September 1, 2019, the stamp duty value of each residential unit must not exceed Rs. 45 lakhs. Stamp duty value is the value adopted or assessed by the state government for stamp duty purposes, not the actual transaction price. A unit may be sold at a price higher than Rs. 45 lakhs and still qualify, provided the stamp duty value does not exceed this limit.
This condition does not apply to projects approved before September 1, 2019.
6. Commercial Area Restriction
The carpet area of shops and other commercial establishments included in the housing project must not exceed 3% of the aggregate carpet area of the project. This ensures the project remains predominantly residential in character.
7. FAR Utilisation
The project must utilise not less than:
- 90% of the floor area ratio permissible under government or local authority rules, where the project is located within the metropolitan cities of Bengaluru, Chennai, Delhi NCR (limited to Delhi, Noida, Greater Noida, Ghaziabad, Gurugram, Faridabad), Hyderabad, Kolkata and Mumbai (whole of Mumbai Metropolitan Region)
- 80% of the permissible floor area ratio, where the project is located in any other place
Floor area ratio (FAR) is the quotient obtained by dividing the total covered plinth area on all floors by the area of the plot of land. This condition ensures developers build at adequate density and do not under-utilise the approved FAR.
8. Only One Housing Project on the Plot
The plot of land must contain only one housing project. Multiple housing projects on the same plot disqualify the deduction.
9. One Unit Per Family
No residential unit in the project shall be allotted to any person if a residential unit in the same project has already been allotted to the spouse or a minor child of that person. For this purpose, family means the individual, their spouse, and their minor children. This condition ensures one family receives only one residential unit within the eligible project.
10. Separate Books of Account
The assessee must maintain separate books of account for the housing project. This is required so that the profits attributable to the eligible project are clearly ascertainable and not commingled with profits from other business activities.
11. Works Contract Exclusion
The deduction is not available where the assessee develops the housing project under a works contract. The developer must be building the project on its own account and not on behalf of another person under a contractual arrangement.

How the Deduction Is Calculated
The deduction is 100% of the profits and gains derived from the eligible housing project for the relevant assessment year. There is no cap on the absolute amount of deduction.
Example: A developer’s gross total income for AY 2025-26 includes Rs. 2 crore profit from an eligible Section 80IBA housing project and Rs. 60 lakh income from other real estate consultancy work. The Section 80IBA deduction is Rs. 2 crore, applied against gross total income. Tax is payable only on the remaining Rs. 60 lakh.
The deduction is available only under the old tax regime. Developers who opt for the new tax regime under Section 115BAC cannot claim Section 80IBA. For a comparison of both regimes and which works better at different income levels, see Income Tax Slabs FY 2025-26 and 2026-27: New vs Old Regime.
Rental Housing Projects: An Additional Category
Budget 2021 expanded Section 80IBA to cover rental housing projects from April 1, 2022. A rental housing project means a project notified by the Central Government in the Official Gazette on or before March 31, 2022, fulfilling conditions as specified in the relevant notification.
Developers who intend to claim the deduction for a rental housing project must verify that their specific project has been notified by the Central Government. The conditions specified in the notification may differ from the standard Section 80IBA conditions applicable to sale-based housing projects.
Section 80IBA vs Section 80-IB(10): Key Differences
Section 80IBA replaced the earlier Section 80-IB(10) of the Income Tax Act 1961, which provided deductions for housing projects from October 1, 1998. The key structural differences between the two provisions are:
| Point | Section 80-IB(10) | Section 80IBA |
|---|---|---|
| Applicable period | Projects from Oct 1, 1998 | Projects approved Jun 1, 2016 to Mar 31, 2022 |
| Unit size basis | Built-up area | Carpet area |
| Metro unit size | 1,000 sq. ft. built-up | 60 sq. mtrs. carpet area |
| Other unit size | 1,500 sq. ft. built-up | 90 sq. mtrs. carpet area |
| Stamp duty cap | Not applicable | Rs. 45 lakhs (from Sep 1, 2019) |
| FAR condition | Not specified | 80% or 90% minimum |
| One unit per family | Not specified | Mandatory |
ITR Filing and Compliance
The deduction under Section 80IBA is claimed in the Income Tax Return for the relevant assessment year. The applicable ITR form depends on the assessee’s legal structure:
- Companies file ITR-6
- Partnership firms and LLPs file ITR-5
- Individuals and HUFs with business income file ITR-3
The deduction is available only under the old tax regime. If the assessee’s total business turnover exceeds the threshold under Section 44AB, a tax audit in Form 3CD is required and the Section 80IBA deduction must be disclosed in the relevant clause.
For complete guidance on ITR due dates including the last date for audit cases, see ITR Filing Last Date 2026.
Practical Scenarios
What if only part of the project has units within the carpet area limit?
Section 80IBA does not permit a proportionate deduction. All residential units in the project must satisfy the carpet area limit. If any unit exceeds 60 sq. mtrs. in a metro city or 90 sq. mtrs. elsewhere, the deduction is not available for the project.
Can a landowner and developer jointly claim the deduction under a joint development agreement?
The deduction is available only to the assessee in the business of developing and building the housing project. In a joint development agreement where the landowner receives constructed units in exchange for land, the developer (not the landowner) claims the Section 80IBA deduction. The landowner’s income from the JDA is subject to capital gains tax separately. For capital gains tax rates and provisions, see Capital Gains Tax FY 2026-27.
What if the project receives multiple approvals at different stages?
The five-year completion period runs from the end of the financial year in which the first building plan approval was granted, not from subsequent approvals or plan amendments. Where multiple approvals exist for the same project, the date of the first approval governs.
What if the project is not completed within five years?
The entire deduction claimed in all earlier assessment years is treated as income of the previous year in which the five-year period expires. This income is taxed at the applicable rates for that year. There is no partial recovery the full reversal applies regardless of how close the project was to completion.
