"So Meriton will have real estate which is business real property, because it's used in their business. So, the fact it's residential, doesn't mean it can never ever be business real property," said Mr Hay-Bartlem.

Where people establish residential property as trading stock and therefore business real property, however, there is a catch, he warned. 

Clients often get unstuck, he said, because they say that they hold the land as trading stock, but don't list it in the financials as trading stock. 

"Very few people who say it's trading stock, actually have it in the financials as trading stock, and yet they try and apply a 50 per cent capital gains discount at the end," he said.

"If it's genuinely trading stock and you sell it, your profit will be ordinary income, not capital gain, so be careful with what you say, we've seen the ATO go and ask for bank loan applications."
