This is an interesting topic for a few reasons.
We (my SP) make significant income from various source in our SP that is not principal of mutuality income. We never declare the non-mutual amounts, some years we make between $10-20k. The auditors report shows we are not paying tax and that we scream principal of mutuality in relation to our SPs finances.
One treasurer once claimed there is a threshold ($ amount) the OC muct pass before the ATO cares about non mutual income?
Is this true?
