Provident fund amendment revises exemption conditions, taxes excess credited interest, and regulates investment of recognised funds. Schedule XI is amended to revise the conditions for provident funds linked to covered or notified establishments, require exemption under section 17 where applicable, omit specified obsolete provisions, and restate the tax treatment of excess interest credited to a recognised provident fund. Interest above the rate fixed by notification is deemed received by the employee and included in total income for the tax year. The amendment also revises the investment clause to regulate the investment or deposit of monies of a recognised or approved fund.
