Section 10(23C) exemption for the relevant year did not require return filing by entities outside the categories expressly covered by the Twentieth Proviso. A later amendment imposing a return-filing condition for specified entities could not be applied to that year. Where the revenue authorities did not find that the substantive exemption conditions were unmet, non-filing of a return alone could not defeat the claim. Exemption was consequently directed to be granted in accordance with law, and the income assessed under "Income from Other Sources" was deleted.
