The ATO each year issues a Determination which outlines the amounts that are acceptable as estimates of the value of goods taken from trading stock for private use by business owners (including their associates) in certain industries who operate as sole traders or in partnership.
The relevant amounts need to be included in the assessable income of the individual for the year.
Note that an adjustment for the GST credits claimed in relation to these amounts also needs to be made.
Fringe benefits tax and a different set of valuation rules apply where the business owner is employed through a company or family trust.
