(i) at a time when the property is owned by the taxpayer, the property is, or is to be, used (whether or not by the taxpayer) wholly or partly in or in connection with the production, supply, carriage, transmission or delivery of goods or the provision of services; and
(ii) a person other than the taxpayer (which person is in this section also referred to as the end‑user) controls, will control, or is or will be able to control, directly or indirectly, that use of the property, and:

(5) In subparagraph (4)(a)(iii) and sub‑subparagraph (4)(b)(ii)(D), a reference to the end‑user is a reference to the end‑user, any of the end‑users (where there are 2 or more end‑users), any associate of the end‑user or of any of those end‑users, or any 2 or more such persons.
(6) For the purposes of subsection (4), property shall be taken not to have been, prior to its acquisition by the taxpayer, owned, and used or held for use, by a person if:

(b) at that time there was in existence an arrangement that the property would be sold to another person and leased by that person to the first‑mentioned person.
(7) Where:
(a) the end‑user consists of all or any of the partners in a partnership; and
(b) a condition of paragraph (4)(a) or (b), as the case may be, is satisfied in relation to any of the partners in the partnership;
that condition shall be taken to be satisfied in relation to all the partners in the partnership.
(8) This section does not apply to property, in relation to a taxpayer, unless the whole or a predominant part of the cost of the acquisition or construction, as the case may be, of the property by the taxpayer is financed directly or indirectly by a debt or debts (which debt is, or debts are, referred to in this subsection as the non‑recourse debt) and the rights of the creditor or creditors as against the taxpayer in the event of default in the repayment of principal or payment of interest:

(i) the assets of the taxpayer;
(ii) any arrangement to which the taxpayer is a party; or

(a) property has been financed by a debt or debts as mentioned in subsection (8); and
(b) the rights of the creditor or creditors as against the taxpayer are, or are capable of being, limited as mentioned in that subsection;
the Commissioner may treat those rights as not being, or capable of being, so limited if the Commissioner is of the opinion, having regard to the circumstances in which the debt was, or debts were, incurred and any other matters that the Commissioner thinks relevant, that it would be reasonable to do so.

there shall be included in the assessable income of the taxpayer of the relevant year of income an amount ascertained in accordance with the formula A (B – C), where:
A is the amount of the relevant deduction.
B is the individual interest of the taxpayer in that net income or partnership loss, being that individual interest expressed as a fraction of the aggregate of the individual interests of the partners in that net income or partnership loss; and

(c) in the case of a loan benefit—the taxpayer, being the recipient or the employee, incurs interest (in this section called the recipients interest) in respect of the loan;
(d) in the case of a benefit other than a loan benefit—the taxpayer, being the recipient or the employee, incurs consideration (in this section called the recipients contribution) to the provider or to the employer in respect of the provision of the recipients transport, the recipients meal, the recipients property or the recipients benefit, as the case may be;
(e) it would be concluded that, in calculating the amount of the recipients interest, or the amount of the recipients contribution, as the case may be, the provider or the employer made an allowance for a particular level of application or use of the benefit in producing assessable income of the taxpayer; and
(f) it would be concluded that the amount of the recipients interest, or the amount of the recipients contribution, as the case may be, would have been greater if it had been calculated without making that allowance;
(g) if the extent of the application or use of the benefit concerned in producing assessable income of the taxpayer is equal to, or less than, that level—a deduction is not allowable to the taxpayer under this Act in respect of the recipients interest or the recipients contribution;
(h) if the extent of the application or use of the benefit concerned in producing assessable income of the taxpayer exceeds that level—the amount of the deduction that, but for this section, has been allowed or would be allowable to the taxpayer under this Act in respect of the recipients interest or the recipients contribution shall not exceed the amount calculated in accordance with the formula:

D is the amount of the deduction that, but for this section, would have been allowable to the taxpayer under this Act in respect of the amount of the recipients interest or the amount of the recipients contribution if it had been calculated without making that allowance; and
A is the amount of that allowance.
(2) Expressions (other than “recipients contribution” and “fringe benefit”) used in this section and in the Fringe Benefits Tax Assessment Act 1986 have the same respective meanings in this section as they have in that Act.

(i) a taxpayer incurs expenditure; and
(ii) a non‑cash business benefit is provided to the taxpayer or another person; and
(b) that benefit is not exclusively for use or application for the purpose of producing assessable income of the taxpayer;

(a) gaining assessable income; or
