68. Attribution of capital gain to spouse
(1) Where a person’s capital gain or a capital gain that has vested in or is treated as having vested in that person during the year of assessment in which it arose can be attributed wholly or partly to-
(a) any donation, settlement or other disposition; or
(b) any transaction, operation or scheme, made, entered into or carried out by that person’s spouse mainly for purposes of reducing, postponing or avoiding that spouse’s liability for any tax, duty or levy which would otherwise have become payable under any Act administered by the Commissioner, so much of the gain as can be so attributed must be disregarded when determining that person’s aggregate capital gain or aggregate capital loss and taken into account when determining the aggregate capital gain or aggregate capital loss of that person’s spouse.
(2) Where a person’s capital gain is derived from-
(a) any trade carried on by that person in partnership or association with that person’s spouse or which is in any way connected with any trade carried on by that spouse; or
(b) that person’s spouse or any partnership or private company at a time when that spouse was a member of that partnership or the sole, main or one of the principal holders of shares in that company,
so much of that gain as exceeds the amount to which that person would reasonably be entitled having regard to the nature of the relevant trade, the extent of that person’s participation therein, the services rendered by that person or any other relevant factor, must be disregarded when determining that person’s aggregate capital gain or aggregate capital loss and taken into account when determining the aggregate capital gain or aggregate capital loss of that person’s spouse.
