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 partnership 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.

Do the thin capitalisation rules apply?

Subject to two exclusions listed below, the thin capitalisation rules will apply to a partnership if:

  • the partnership has at least one partner which is an Australian resident (an Australian partnership) and either
    • the partnership, or any of its associate entities, is an Australian controller of an Australian controlled foreign entity (explained below) or carries on business overseas at or through a permanent establishment, or
    • that partnership is foreign controlled, either directly or indirectly, or
     
  • the partnership does not have any partners that are Australian residents and the partnership carries on business in Australia at or through a permanent establishment or otherwise has assets that produce assessable income.

Exclusions

The thin capitalisation rules will not apply if:

  • the partnership's debt deductions (combined with the debt deductions of its associate entities) do not exceed $250,000 in the income year, or
  • in the case of an Australian partnership which is not foreign controlled, the combined value of the partnership's Australian assets and the Australian assets of its associates comprise at least 90% of the value of the total assets of the partnership and those associates.

Control

The rules measuring control take into account both direct and indirect interests that the partnership holds in the other entity (or vice-versa), and the direct and indirect interests that associate entities of the partnership hold in the other entity. This means an Australian partnership can be an Australian controller of a foreign entity even if it holds a direct interest of less than 50% in the foreign entity.

What if the thin capitalisation rules apply?

If the thin capitalisation rules apply to the partnership or further information is required, see the Guide to thin capitalisation. If the thin capitalisation rules apply, the partnership must complete the Thin capitalisation schedule 2010, unless the partnership was a subsidiary member of a consolidated group at any time during the income year and has completed Z2 item 2.

Post the completed schedule to:

Australian Taxation Office
PO Box 1365
ALBURY  NSW  2640

What if the thin capitalisation rules are breached?

If the thin capitalisation rules are breached, some of the partnership's debt deductions may be denied. The amount denied for business income is shown in B Expense reconciliation adjustments item 5. If the partnership 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 labels must exclude the debt deductions denied.
