The draft QWBA describes how to calculate the deductible expenditure when a homeowner has flatmates. It also looks at the interest limitation, residential ring-fencing and mixed-used asset rules and if they apply. 

In CAANZ’s view, the QWBA will be a valuable resource for taxpayers and agents. CA ANZ supports the publication of the draft QWBA. CAANZ also suggests some aspects of the items be reviewed and clarified with additional references.
