Deemed accumulated income rule limits investment obligation and ties permitted modes to actual investment, changing compliance exposure.
The provision designates a deemed accumulated income amount calculated as a proportion of regular income after reductions for application of income and amounts accumulated or set apart; that deemed amount is excluded from the accumulated-income regime and, if invested or deposited, must be placed in modes permitted by the applicable investment provision. The enacted text clarifies the reduction base by expressly referencing the application-of-income mechanism and conditions the statutory constraint on investment modes upon an actual investment or deposit.
