42Revocation of election and subsequent elections

1. A person who has made an election in relation to a child support year may revoke the election, before or during the child support year, by giving notice to the Commissioner; and the revocation takes effect from the start of the election period to which any election applied.

2. If an election is in effect but the person then makes a later election,—

3. if the Commissioner accepts the later election,—
   1. the later election takes effect from the start of the month in which the notice of election is given, and section 41 applies accordingly; and
   2. the earlier election ceases to have effect on the last day of the previous month:
4. if the Commissioner does not accept the later election because the amount of year-to-date income plus the new estimated income is more than 85% of the person's original adjusted income, then the earlier estimate is deemed to be revoked:
5. if the Commissioner does not accept the election for any other reason, the earlier estimate remains in effect.

6. A revocation is of no effect to the extent that it is inconsistent with an income amount order.
