(1) This section allows the Registrar to amend an assessment of child support payable by or to a parent for some days in a child support period if:
(a) those days occur in the application period for an income election that the parent has made; and
(b) the Registrar has given the parent a notice under section 160 or subsection 162A(2) requiring or requesting the parent to notify the Registrar of the occurrence of an event that may affect the accuracy of an estimate on which the election is based.
(2) If the parent gives notice of the event as required or requested under section 160 or subsection 162A(2), the Registrar may amend the assessment to affect the annual rate of child support payable by or to the parent for those days in the child support period that occur on or after the day the parent gives notice.
(3) If the parent does not give notice of the event as required or requested under section 160 or subsection 162A(2), the Registrar may amend the assessment to affect the annual rate of child support payable by or to the parent for those days in the child support period that occur on or after the day the event occurred.
(4) This section does not:
(a) affect the operation of section 160 or 162A; or
(b) prevent the Registrar from making a new assessment for part of the child support period.
