FORM NO. 16
[See rule 31(1)(b)]
Certificate of donation under section 45(4)(a) made to the research association, university, college or other institution or company

Under the new Income-tax Rules, 2026, it is important to first clarify a major change in terminology: The old Form 16 (used for Salary TDS under the 1961 Act) has been replaced by Form No. 130.

Under the new 2026 framework, Form No. 16 is now a completely new form designated as the Annual Certificate to Donors for Scientific Research. It is governed by Section 45(4)(a) read with Section 45(3) of the Income-tax Act, 2025.

Here are all the key points regarding the new Form 16:

1. Purpose of the Form Form 16 is a statutory annual certificate issued to donors who contribute sums for scientific research. It serves as documentary support that facilitates the verification of tax deductions claimed by the donor under Section 45 of the new Act.

2. Who Issues and Receives It

Issued By: It is issued by the prescribed undertaking or institution (such as a research association, university, college, approved Indian R&D company, or National Laboratory) that receives the eligible sums for scientific research.
Received By: It is issued directly to the donor who made the contribution.

3. Nature of the Certificate

Annual, Not Transactional: Form 16 is an annual certificate that aggregates all donations received from a specific donor during the tax year. It is not a transaction-wise receipt and does not acknowledge individual donations separately.
While an institution can still issue separate commercial receipts or acknowledgments at the time of the donation, those are distinct from this statutory annual certificate.

4. Frequency and Due Date

It must be issued once for each tax year.
The due date for issuing Form 16 is on or before 31st May immediately following the end of the relevant tax year.

5. Linkage with Form 15 Form 16 is intrinsically linked to Form 15 (the annual statement of donations furnished by the institution to the Income-tax Department). Form 16 is systematically generated based on the data the institution reports in Form 15, ensuring consistency between the donor’s certificate and the department’s records.

6. Structure and Contents The system-generated electronic certificate contains the following details:

Name and approval details of the prescribed institution receiving the funds.
The donor’s name, address, and Permanent Account Number (PAN).
The aggregate amount of the donation received during the tax year.
The specific tax year to which the donation relates.
The relevant clause of section 45(3) under which the donation falls.

7. Specific Applicability (Not for General Charities) Form 16 applies only to donations for scientific research under section 45. It does not apply to general charitable donations, which are governed by an entirely separate reporting and certificate framework (such as Form 114).

8. Legal Implications and Corrections

No Automatic Deduction: Simply possessing Form 16 does not guarantee the donor a tax deduction. It is a certification requirement; the actual deduction remains subject to the donor fulfilling the conditions under section 45 and verification by the Income-tax Department.
Corrections: If any error or omission is identified in the certificate, the institution is permitted to issue a corrected or revised Form 16.
