Certificate for non-deduction of tax on interest: Form 15C covers banking companies and insurers to receive interest without withholding. Amendment substitutes 'banking company or an insurer' for 'banking company' in rule 29B, adds an explanation adopting the Insurance Act definition of 'insurer', and replaces Form 15C. The new Form 15C is for banking companies or insurers to apply for a certificate authorising receipt of interest (other than interest on securities) and other non-dividend sums without deduction of tax, requiring declarations on non-resident status, branch operations in India, head office location, entitlement to receive specified receipts, and compliance with rule 29B.
