Appendix 3: Thin capitalisation

Last updated 11 February 2019

The thin capitalisation provisions reduce certain expenditure (called debt deductions) incurred in obtaining and servicing debt where the debt used to finance the Australian operations of a trust exceeds the limits set out in Division 820 of the ITAA 1997. These rules ensure that taxpayers fund their Australian operations with an appropriate amount of equity.

What if the thin capitalisation rules affect you?

If the thin capitalisation rules affect you, the trust must complete the International dealings schedule 2015, unless the trust was a subsidiary member of a consolidated group or MEC group for the entire income year.

Where the trust is a member of a consolidated group or MEC group for the whole income year and the thin capitalisation rules apply, the responsibility for preparing the schedule will rest on the head company of the group.

Where a return is required because the trust had a period in the income year when it was not a member of a consolidated group or MEC group (a non-membership period) the trust should complete an International dealings schedule 2015 where the thin capitalisation rules apply to the trust during the non-membership period. For information about reporting multiple non-membership periods during the year, see the Consolidation reference manual, sheet C9-5-110.

The International dealings schedule is available through the electronic lodgment service (ELS) or complete and lodge the paper schedule.

What if the thin capitalisation rules are breached?

If the thin capitalisation rules are breached, some of the trust’s debt deductions may be denied. The amount denied for business income is shown in B Expense reconciliation adjustments item 5. If the trust incurred debt deductions for other types of income (for example, rental income, dividend income or foreign income) the amount of deductions shown at the relevant entries must exclude the debt deductions denied.
