Penalty framework under income-tax law is amended to exclude income with additional tax paid from penalty basis. Section 439 is amended by inserting income referred to in section 195(1)(b) into sub-section (11), and by adding a new clause (g) for that purpose. A new sub-section further provides that where additional income-tax is paid in accordance with section 267(5)(ii), the income on which such tax is paid shall not form the basis for imposition of penalty under this section.
