<h1>Taxation option for domestic manufacturers limited to business income, while incomes under scheduled rates remain separately taxed, with retrospective effect.</h1> The amendment clarifies that the concessional taxation option under Section 115BA is confined to income arising from manufacture, production, research or distribution carried on by the domestic company; amounts subject to separate scheduled rates continue to be taxed under those schedules. The clarification is given retrospective effect from 1 April 2017 and applies to assessment year 2017-18 onward.
