Securities for tax purposes include SCRA defined instruments, stocks and shares, and securitisation trust debt securities. Definition of securities for income tax purposes is context specific: generally tied to the Securities Contracts (Regulation) Act; expressly includes stocks and shares; treats securities as similar when they confer identical rights and remedies despite differences in form; and, for taxation of securitisation trusts, limits securities to debt instruments issued by a Special Purpose Vehicle under Reserve Bank securitisation guidelines.
