The limited power to reduce or waive interest under section 139(8) and rule 117A applied only if the prescribed conditions, including any necessary prior approval, were satisfied; those conditions were not shown here. The original non-levy was therefore not a conscious waiver but a mistake apparent from the record, and rectification under section 154 was permitted to levy the interest. en-us Tue, 06 Apr 1976 00:00:00 +0530 Thu, 08 Apr 2010 12:05:25 +0530 TaxTMI RSS Generator https://www.taxtmi.com/caselaws?id=38667 Income-tax Officer's failure to charge interest for late filing was held to be rectifiable where the return was filed after the maximum extended date and the proviso to section 139(1) made interest mandatory.
