Reduction of taxable income for recent residential buildings: capped per unit relief and expanded multi year benefit introduced. Amendment revises computation of income from buildings by providing a multi year reduction for buildings whose erection is completed after the later cut off, allowing an aggregate deduction across residential units equal to each unit's annual value when below a monetary threshold or a fixed capped amount when above, while ensuring that income from any residential unit is not a loss; it also increases the monetary cap used in related income computations.
