Section 80-IBA: Deduction for Profits from Housing Projects
Section 80-IBA of the Income-tax Act, 1961 provided a 100% deduction of qualifying profits from the business of developing and building eligible housing projects. It was later extended to qualifying notified rental housing projects. Although the Income-tax Act, 2025 has replaced the 1961 Act, the benefit is preserved for eligible projects through section 142 of the 2025 Act.
What deduction is available?
Where the applicable conditions are satisfied, the deduction is equal to 100% of the profits and gains derived from the eligible business. The housing-project deduction applies to qualifying development and construction activity. A corresponding 100% deduction was introduced for profits from qualifying rental housing projects.
Key conditions for an eligible housing project
The statutory conditions should be read together and applied to the particular project. Important requirements include the following:
| Requirement | Section 80-IBA condition |
|---|---|
| Approval period | The housing project must have been approved by the competent authority after 1 June 2016 and on or before 31 March 2022. |
| Completion | The project must generally be completed within five years from the date of approval. Where approval is obtained more than once, the first approval of the building plan is relevant. Completion is linked to obtaining the written completion certificate for the project as a whole from the competent authority. |
| Commercial area | Carpet area of shops and other commercial establishments must not exceed 3% of the aggregate carpet area. |
| Only project on plot | The project must be the only housing project on the specified plot of land. |
| Allotment restriction | Where a residential unit is allotted to an individual, another residential unit in the same project cannot be allotted to that individual, the individual's spouse or minor children. |
| Separate accounts | The assessee must maintain separate books of account for the housing project. |
Projects approved on or after 1 September 2019
For projects approved on or after 1 September 2019, the substituted conditions include revised plot-size and residential-unit limits, a stamp-duty-value ceiling and floor-area-ratio requirements.
Specified metropolitan locations: Bengaluru, Chennai, Delhi National Capital Region limited to Delhi, Noida, Greater Noida, Ghaziabad, Gurugram and Faridabad, Hyderabad, Kolkata, and the whole Mumbai Metropolitan Region.
- Minimum plot area: 1,000 square metres in the specified metropolitan locations; 2,000 square metres elsewhere.
- Maximum residential-unit carpet area: 60 square metres in the specified metropolitan locations; 90 square metres elsewhere.
- Stamp duty value of a residential unit: not more than Rs. 45 lakh.
- Minimum floor area ratio utilisation: 90% in the specified metropolitan locations and 80% elsewhere.
Rental housing projects
Section 80-IBA also covered profits from developing and building a qualifying rental housing project. For this purpose, a rental housing project is one notified by the Central Government in the Official Gazette on or before 31 March 2022 under the statutory provision and satisfying the conditions specified in the notification.
Works contracts are excluded
The deduction does not apply where the assessee merely executes the housing project as a works contract awarded by another person, including the Central Government or a State Government. The provision is directed at the eligible business of developing and building the project, not a contractor carrying out an awarded works contract.
What happens if the project is not completed in time?
If a project for which deduction was claimed and allowed is not completed within the prescribed period, the deductions previously allowed are treated as business income of the previous year in which the permitted completion period expires. This recapture rule makes timely completion and the prescribed completion certificate important.
No double deduction of the same profit
Where profits from the eligible housing-project business have been claimed and allowed as a deduction under section 80-IBA for an assessment year, a deduction to the extent of those profits cannot also be claimed under another provision of the Act.
Important definitions
Carpet area
Section 80-IBA adopts the meaning of carpet area from section 2(k) of the Real Estate (Regulation and Development) Act, 2016. Broadly, it is the net usable floor area of an apartment, subject to the inclusions and exclusions stated in that Act.
Competent authority
The competent authority is the authority empowered under the law in force to approve the building plan.
Floor area ratio
Floor area ratio is the quotient obtained by dividing the total covered plinth area on all floors by the area of the plot.
Housing project
A housing project is a project consisting predominantly of residential units together with such other facilities and amenities as the competent authority may approve, subject to the statutory conditions.
Residential unit
A residential unit is an independent housing unit with separate facilities for living, cooking and sanitation, distinctly separated from other residential units and independently accessible in the manner contemplated by the provision.
Stamp duty value
Stamp duty value means the value adopted, assessed or assessable by a Central or State Government authority for payment of stamp duty on immovable property.
Section 80-IBA after the Income-tax Act, 2025
The Income-tax Act, 2025 contains the corresponding transition provision in section 142. It applies where profits arise from housing projects or rental housing projects referred to in section 80-IBA of the Income-tax Act, 1961 and the assessee would have been eligible to claim the deduction under that provision had the 1961 Act not been repealed. The amount and period of deduction continue to be determined by reference to the former section 80-IBA conditions.
Practical checklist before claiming the deduction
- Confirm the date and competent authority of the first project approval.
- Verify that the project falls within the statutory approval window and applicable project category.
- Check plot area, unit carpet area, commercial carpet area, stamp duty value and floor area ratio conditions applicable to the approval date and location.
- Maintain project-wise books and supporting records.
- Obtain and retain the written completion certificate for the project as a whole.
- Ensure the activity is development and building of the eligible project and not merely execution of an awarded works contract.
- For current claims, also examine section 142 of the Income-tax Act, 2025 and the applicable transition provisions.
