CBDT has issued detailed Frequently Asked Questions (FAQs) on Form 18, offering greater clarity to taxpayers and developers seeking tax benefits for affordable housing projects under the Income Tax Act, 2025.
Introduced under Rule 36 of the Income Tax Rules, 2026, Form 18 is a mandatory application for obtaining notification of an affordable housing project as a specified business under Section 46 of the Act. Without this notification, eligible businesses may not be able to claim the intended tax incentives available for such projects.
The FAQs aim to answer practical concerns surrounding eligibility, disclosures, documentation, project requirements and compliance obligations.
What is Form 18?
Form 18 is an application form prescribed for taxpayers seeking notification of an affordable housing project as a specified business under Section 46 of the Income Tax Act, 2025.
The notification is important because it allows eligible housing projects to avail tax benefits granted under the law. In simple terms, developers or businesses planning qualifying affordable housing projects must first secure approval through Form 18 before claiming associated deductions or incentives.
Who Needs to File Form 18?
According to the FAQs, Form 18 must be filed by an assessee who intends to obtain notification for an affordable housing project that is either already being carried on or is proposed to be undertaken.
The government has clarified that filing Form 18 is mandatory for availing benefits under Section 46. Failure to secure notification may result in the denial of tax benefits otherwise available to eligible projects.
What Information Must Be Furnished?
The FAQs reveal that Form 18 requires extensive project and taxpayer disclosures.
Assessee Details
Applicants are required to furnish basic information, including:
- Name and address
- PAN details
- Residential and legal status
- Contact details such as email ID and phone number
Affordable Housing Project Details
The applicant must also disclose:
- Name and address of the specified business
- Affordable housing project name
- Complete project location
- Whether the project is situated in a specified city
Further, the form requires detailed disclosures regarding the project’s composition, including the total number of units , category-wise rentable area for EWS (Economically Weaker Sections), LIG (Low Income Group), MIG (Middle Income Group) and other segments, as well as common facilities and total allocable area.
Conditions for Notification of Affordable Housing Projects
To qualify for notification, applicants must satisfy the conditions prescribed under Rule 36(5) of the Income Tax Rules, 2026.
Compliance with area-related conditions has to be specifically reported by furnishing category-wise details of units and rentable area while confirming adherence to percentage thresholds prescribed under tax rules. This indicates a stronger compliance-focused approach to ensure only genuine affordable housing projects receive benefits.
Additional Project Disclosures Required
Apart from core project details, Form 18 also asks applicants to provide:
- Proposed investment in the project
- Expected and actual commencement dates
- Details of nearby or adjacent land or projects
- Whether the project is independent or part of another development
The applicant must clearly specify whether the affordable housing project is a standalone project or merely an extension of another housing development.
Land Ownership and Development Agreements
The FAQs further clarify that applicants must disclose the nature of land ownership or title for the project site.
In cases where the project is being developed through agreements with third parties, developers are required to provide details of such agreements, mention all concerned parties, and attach copies of relevant arrangements. This requirement is likely intended to improve transparency in housing project structures.
Declaration, Verification and Accuracy of Information
Form 18 also includes a mandatory declaration requiring applicants to confirm that the affordable housing project will continue operating during the period for which tax benefits are claimed.
The form must be signed and verified by the applicant or an authorised signatory, along with designation details. While certain assessee information may be pre-filled using Income-tax Department records, the applicant remains responsible for verifying the correctness of all submitted information.
Importantly, authorities have warned that furnishing false or incorrect details may result in denial or withdrawal of notification under Section 46 and may also attract legal consequences under the Income Tax Act, 2025.
Why Form 18 Matters
The release of FAQs on Form 18 signals the government’s intent to strengthen transparency and compliance in the affordable housing sector while ensuring that tax incentives are extended only to eligible projects.
For developers and businesses planning affordable housing ventures, Form 18 is more than a procedural filing—it acts as the gateway to statutory recognition and tax benefits under the new tax framework. Timely compliance and accurate disclosures could therefore become critical for projects seeking to maximize fiscal incentives while avoiding future disputes with tax authorities.
