Generating income 'on the side' from house/room rental channels such as Airbnb should be included in your tax return. Furthermore, there are CGT implications when you come to sell your house in the future. The ATO's data matching measures are making it easier than ever to catch people out who are not declaring this income.
“People often think their main job is what they should declare and anything they earn through something like Airbnb is just pocket money. There used to be a same thought about people using eBay, but it’s income that needs to be included on your tax return,” he said. “The average person who uses Airbnb might bring in something like $4,000 to $7,000 a year. That’s a fair amount of money to be going undeclared each year.”
