In 2014 TAXVINE No 44 (28 November 2014), Member 191 wrote requesting the ATO to improve their Division 293 assessment notices, by breaking "total earnings" into their constituent parts.
THE ATO NOW RESPONDS
"Thank you for your feedback, we will look into the feasibility of splitting out the components of Total Earnings on the notice. We are committed to improving our administration of Div 293 and have already undertaken a complete redesign of our correspondence as a result of taxpayer feedback. These new letters will start to issue from March.
In the short term we include a link to an online calculator you can use to work out the income for the surcharge purposes figure we used. Please note that you will need to disregard any reportable superannuation contributions reported on the income tax return."
