Safe harbour rules expanded to cover income under s9(1)(i) and arm's length price determinations, altering assessment scope. The substituted provision makes determination of income referred to in clause (i) of section 9(1) and determination of arm's length price under sections 92C and 92CA subject to safe harbour rules framed by the Board, thereby extending safe harbour coverage to both income-attribution under section 9(1)(i) and transfer-pricing valuations; the amendment takes effect from 1 April 2020 and applies to subsequent assessment years.
