Dividend income exclusion: dividends referred in section 115-O are excluded from the scope of section 115AD. The amendment inserts the phrase 'other than income by way of dividends referred to in section 115 O' into clause (a) of sub section (1) of section 115AD, excluding dividend income governed by section 115 O from the income chargeable under section 115AD and thereby creating an explicit carve out for such dividends from that provision's scope.
