(1) Where a person has created a trust in respect of any income or property (including money) and:
(a) the person has power, whenever exercisable, to revoke or alter the trusts so as to acquire a beneficial interest in the income derived by the trustee during the year of income, or the property producing that income, or any part of that income or property; or
(b) income is, under that trust, in the year of income, payable to or accumulated for, or applicable for the benefit of a child or children of that person who is or are under the age of 18 years;
the Commissioner may assess the trustee to pay income tax, under this section, and the trustee shall be liable to pay the tax so assessed.
(2) The amount of the tax payable in pursuance of this section shall be the amount by which the tax actually payable on the person's own taxable income by the person who created the trust is less than the tax which would have been payable by the person if he or she had received, in addition to any other income derived by the person, so much of the net income of the trust estate as:
(a) is attributable to the property in which he or she has power to acquire the beneficial interest;
(b) represents the income, or the part of the income, in which he or she has power to acquire the beneficial interest; or
(c) is payable to or accumulated for, or applicable for the benefit of, a child or children of that person who is or are under the age of 18 years.
(2A) Where any property the subject of a trust has been converted into other property, this section shall apply in the same way as if the trust had originally been created in respect of that other property.
(2B) In the application of subsection (2) in determining the amount of tax that is payable by a trustee of a trust estate in pursuance of this section, the reference in that subsection to the net income of the trust estate shall be read as a reference to that net income reduced by:
(a) so much (if any) of that net income as is attributable to a period when the person who created the trust was not a resident and is also attributable to sources out of Australia; and
(b) so much (if any) of that net income as is not covered by paragraph (a) and represents an amount included in the assessable income of any taxpayer under section 102AAZD.
(3) Where this section is applied to the assessment of the income of a trust estate or part thereof derived in the year of income, no beneficiary shall be assessed in his or her individual capacity in respect of his or her individual interest in the income or part to which this section has been so applied, and the trustee shall not be assessed in respect of that income or part otherwise than under this section.
