Exemption from withholding tax allows interest on securities paid to exempt charitable trusts without TDS deduction. Payments to Ramakrishna Math and Ramakrishna Mission, Kolkata, whose income is exempt under section 10(23C)(iv), may be made without deduction of tax at source; interest on all securities covered by section 193 - including Central and State Government securities previously specified - may be paid to these assessees without TDS.
