Commonwealth Consolidated Acts Commonwealth Consolidated Acts(1) Before a provisional notional assessment relating to a child becomes a notional assessment under section 146E, a parent of the child may elect that, for the purposes of making the provisional notional assessment, the parent's adjusted taxable income for the 12 month period beginning on the particular day in the child support period in respect of which the provisional notional assessment is made is the amount estimated by the parent.
(2) However, a parent may not make an election under this section in relation to a child if an order or determination referred to in paragraph (a) of the definition of income amount order is in force, or would be in force but for the existence of the relevant child support agreement, in relation to the parent and the particular day in the child support period in respect of which the provisional notional assessment is made.
Election must be for amount less than adjusted taxable income for last relevant year of income
(3) The parent may make an election relating to a child only if the amount that he or she estimates under subsection (1) is not more than 85% of the total of the parent's adjusted taxable income for the last relevant year of income for the child support period.
How election is made
(4) The parent makes the election by giving notice of it to the Registrar in the manner specified by the Registrar. The notice must specify the amount the parent estimates to be his or her adjusted taxable income.
