<h1>Scientific research donation certificates streamline deduction verification through annual donor-wise reporting, Form 16 linkage, and corrected issuance.</h1> Form 16 serves as the annual donor-wise certificate for contributions made to prescribed institutions for scientific research and is used to support verification of deductions claimed under the Income-tax Act, 2025. The certificate records aggregate donations received during the tax year, is not a receipt for individual transactions, and operates separately from transaction-level acknowledgments issued by the institution. It is linked to Form 15, must be issued once in each tax year on or before 31 May, and may be corrected if errors are found.
