Thin Capitalisation Workpapers – Company and Consolidated Company Tax

A new Thin Capitalisation supporting schedule has been introduced to track disallowed amounts for corporates:
  • FRT Disallowed Amounts {A32}
This schedule is available in both Company and Consolidated calculations and tracks:
  • Current period disallowed amounts
  • Prior period recoupment,
Amounts from this schedule flow through to Tax Effect Accounting and ATO Forms areas. Additional data flow has been introduced from the
Thin capitalisation general
{A30}
 and FRT
Disallowed Amounts {A32}
 to the
International dealings schedule – Section D Thin capitalisation {RG3}.
Updates have been made to the
Thin capitalisation general
{A30}
 to align amounts with the various tax treatments, both interest expense and interest income amounts now reflect the tax-deductible amounts. Other minor wording and format updates have also been applied.
