Ms James said information substantiating the market value such as the methodology used to calculate that the value of each asset will also need to be kept.

“[For example], if the asset was a parcel of shares, was it the listed share price at close of business on the day of the election for the shares?” she said.

“Or if we’ve got property, have we got independent valuer’s reports to ascertain the value of the property?”

Ms James said the ATO typically does accept real estate appraisals for the valuation of a property but where the client is “getting to the pointy end of the value and they’re getting close to the $1.6 million, or they’re trying to argue that the value of a property has dropped” for example, “those might be circumstances where you might try and get an independent valuer’s report”.

“We’ve already seen this with the small business CGT concessions. That’s an area where the ATO really looks at it closely,” she said.

“We can expect valuations around CGT relief and the $1.6 million retirement cap to be a hot area for audit and review for the ATO. So, how we set out our records and substantiate our values will become important.”
