Form 12 Income Tax Rules 2026 pdf download and Key points

FORM NO. 12
[See rule 29(2)(e)(ii)]
Report to be submitted by the prescribed authority to the Chief Commissioner of Income-tax having jurisdiction over the company

Under the Income-tax Rules, 2026, Form No. 12 replaces the erstwhile Form 3CL. It is governed by Section 45(2) of the Income-tax Act, 2025, and Rule 29 of the Income-tax Rules, 2026.

Here are all the key points regarding Form No. 12:

1. Purpose of the Form Form 12 is a statutory reporting form through which the prescribed authority officially submits its findings, examination, and certification regarding an approved in-house research and development (R&D) facility. It plays a central role in the administration of tax deductions for in-house R&D expenditure by certifying the nature, adequacy, and recognition status of the facility, and by quantifying the eligible expenditure incurred.

2. Who Should File (And Who Should Not)

  • Filed by the Prescribed Authority: Form 12 is mandatorily furnished by the prescribed authority, namely the Secretary, Department of Scientific and Industrial Research (DSIR), or such authority as notified under Rule 29.
  • Not Filed by the Company: It is not required to be filed by the company claiming the tax deduction. The obligation is entirely institutional and independent of the company.

3. To Whom is it Furnished? The DSIR submits Form 12 to the Chief Commissioner of Income-tax having jurisdiction over the company. A copy of the report is also provided to the company for its own records.

4. Frequency and Due Dates

  • Frequency: It is required to be furnished annually (or periodically) in respect of each approved in-house R&D facility, covering the expenditure incurred during the relevant tax year.
  • Mode of Filing: It is envisaged to be submitted electronically to enable system-driven processing, cross-linkage with Form 11 (the application/agreement), and better monitoring.

5. Structure and Contents of the Form Form 12 systematically captures information across two principal parts:

  • Part A – Evaluation of In-house R&D Facility: Covers the particulars of the company and its principal officer, the nature of the business and its linkage with research objectives, the details and adequacy of the in-house R&D facilities, DSIR recognition details, and confirmation of the agreement entered into under Form 11.
  • Part B – Certification of Expenditure: Reports the details of eligible capital and revenue expenditure incurred on the approved facility, and any information relating to the disposal or transfer of assets, if applicable.

6. Role in Tax Deductions and Legal Implications

  • Basis for Verification: The expenditure figures certified in Form 12 provide an objective and technical basis for the tax authorities to examine the deduction claims made by the company under Section 45(2).
  • No Automatic Deduction: While Form 12 is a critical input for verification, it does not automatically determine the final allowability of the deduction. The actual deduction remains subject to the company’s compliance with the Act and Rules, and verification/assessment by the Income-tax Department.
  • Consequences of Discrepancies: Any discrepancies or adverse findings reported by the DSIR in Form 12 may lead to further verification by the Income-tax Department and could negatively impact the deduction claimed by the company.
