In a writ petition filed by small investors, Karnataka High Court Held that provisions of Section 206AA of the Income Tax Act are contrary to provisions of Section 139A of the Act. Accordingly, provision of Section 206AA were made inapplicable to persons and was read down from the Act only for those persons whose income was less than the taxable limits. However, the High Court made it very clear that the provisions of the Section 206AA are applicable to the persons whose income is more than the taxable limits.
Accordingly, the High Court Guided the Banks and the Financial Institutions that they shall not invariably insist upon PAN from small investors who intend to open an account in the bank or financial institution.
