Increased ATO focus on short-term rentals
What property owners need to know before they list
If you earn income from Airbnb or other short-term rental platforms, the ATO is paying much closer attention in 2026, and holiday home owners are firmly in the spotlight.
Wollongong, the South Coast, Southern Highlands and the Sutherland Shire are popular lifestyle destinations and prime locations for short-term rentals. For many property owners, listing a holiday home on Airbnb or similar platforms seems like an easy way to generate extra income while still enjoying the property personally.
However, the tax rules around holiday homes and short-term rentals are tightening, and the ATO has made it clear that this is an area under increased scrutiny. Property owners who misunderstand or stretch the rules risk denied deductions, amended assessments and unexpected tax bills.
Why the ATO is paying closer attention
The ATO has identified widespread over-claiming of deductions on holiday homes that are predominantly used for private purposes. In response, updated guidance draws a firm line between:
- ·Genuine income-producing short-term rental businesses, and
- ·Private holiday homes that are only occasionally rented out
The key principle is simple but often misunderstood:
Deductions are only available when the property is mainly used to produce assessable income.
Importantly, “mainly” does not simply mean counting the number of weeks rented versus used privately. The ATO looks at how the property is made available, when it is available, and whether the rental activity is genuinely commercial.
What the ATO considers a red flag
The ATO has outlined several indicators that suggest a holiday home may not be genuinely income-producing. These include:
- ·Overpricing the property so it is unlikely to be booked
- ·Blocking out peak periods, such as school holidays, long weekends and summer
- ·Restrictive booking conditions, such as refusing weekend stays or requiring long minimum stays during off-peak periods
- ·Advertising that appears tokenisticrather than aimed at attracting real bookings
If a property is structured in a way that discourages tenants, the ATO may conclude that the main purpose is private use rather than earning income and there for not eligible to claim deductions.
What genuine commercial activity looks like
The ATO expects a genuine short-term rental operation to show clear commercial intent. This typically includes:
- ·Market-based pricing comparable to similar local properties
- ·Availability during high-demand periods, not just quiet times
- ·Consistent advertising on public platforms
- ·A willingness to accept reasonable bookings
- ·Thorough record-keeping, including booking calendars, enquiries, rejected requests, invoices and maintenance records
These factors help demonstrate that the property is genuinely being operated to produce income, not simply listed “on paper.”
Record-keeping and long-term tax consequences
If you claim deductions for a holiday home, you must be able to substantiate that the property was genuinely available for rent during the periods claimed. This goes beyond just keeping Airbnb statements.
It’s also important to remember that earning rental income can have capital gains tax (CGT) implications, even for properties that were once your main residence. This means records may need to be retained for the entire period of ownership.

Frequently Asked Questions
Can I claim full deductions if I only rent my holiday home part of the year?
Not necessarily. The ATO looks at whether the property is genuinely available for rent on commercial terms, not just how many weeks it is rented. If the property is mainly used for private purposes or structured to discourage bookings, deductions may be limited or denied.
Does listing a property on Airbnb automatically make it income-producing?
No. Simply listing a property is not enough. The ATO considers factors such as pricing, availability during peak periods, booking restrictions and overall commercial intent. If the listing appears tokenistic, the property may be treated as primarily private use for tax purposes.
