GST on Airbnb in Australia: Calculator & Rules

Most Australian Airbnb hosts don’t charge GST on their nightly rate, even if turnover sits above the threshold that catches every other small business. The reason is a quiet provision in the GST law called ‘input-taxed supplies’, which treats residential rent as a category outside the normal GST system. Until the property tips into ‘commercial residential premises’, at which point the rules flip.

This is the part most blog posts on the topic miss, so we’ll work through both sides carefully and hedge where the ATO hedges.

The default position: no GST

If you rent out a residential property on Airbnb, Stayz or Booking.com – a holiday house, a granny flat, a self-contained apartment, a spare room – the income is treated as residential rent under the ATO’s GST rules. That makes it ‘input-taxed’.

Input-taxed means four things in plain terms:

• You don’t charge GST on the nightly rate, regardless of how much you earn.
• You don’t claim GST credits on related expenses (cleaning, linen, the new mattress, the property manager’s fee).
• The $75,000 GST threshold doesn’t apply to this income, because the income isn’t taxable in the first place.
• You don’t lodge a BAS for this income, because there are no taxable supplies to report.

The ATO’s GST and residential property page is the official line on this. It treats short-stay residential lets the same as long-term residential rent.

For most Airbnb hosts running one or two properties, this is the start and the end of the GST conversation. Income tax still applies – the ATO expects every dollar declared as rental income – but GST does not.

When the answer flips: commercial residential premises

The exception that catches more sophisticated operators is ‘commercial residential premises’. If the property is genuinely operated like a hotel, motel, inn, hostel, boarding house or serviced apartment, the GST treatment changes.

The ATO’s Commercial residential property guidance lists the indicators that move a property out of ‘residential’ and into ‘commercial residential’:

• Multiple unrelated guests under separate occupancy agreements at the same time
• Central management of bookings, cleaning, linen and check-in
• On-site services typically associated with a hotel (reception, daily housekeeping, breakfast service, on-site duty manager)
• Physical layout designed for short stays, not permanent living
• Marketing and operation as a hotel-like business

A single Airbnb listing of a self-contained apartment usually doesn’t meet enough of these to qualify. A managed serviced-apartment block where the owner contributes one unit to the pool often does. The ATO publishes a specific guide on Holiday apartments in commercial residential properties for exactly this scenario.

If the property is commercial residential, GST applies on bookings. The host charges 10% GST on the nightly rate, claims GST credits on related expenses and lodges quarterly BAS like any other registered business.

The $75,000 threshold (and why it’s misleading)

The $75,000 turnover figure that triggers compulsory GST registration only counts taxable supplies and GST-free supplies. Input-taxed supplies, including residential rent, do not count toward that threshold.

A pure residential Airbnb earning $200,000 a year is still under the threshold for GST purposes. A commercial-residential operator earning $50,000 a year still has the option to voluntarily register if they want to claim GST credits on inputs.

The ATO’s Registering for GST page sets out the registration tests. Read it before assuming the threshold applies the way you think it does.

How to calculate GST when it does apply

If the ATO’s tests place your property in commercial residential territory, the calculation is the same as any other GST scenario.

• Nightly rate exclusive of GST: Net × 1.10 = Gross. A $300 ex-GST nightly rate becomes $330 inclusive.
• Nightly rate inclusive of GST: Gross ÷ 11 = GST. A $330 inclusive nightly rate contains $30 GST and $300 net.
• GST credits on supplies: Gross ÷ 11 = GST credit on each receipt. An $880 cleaning invoice gives you an $80 input credit.
• Net BAS figure: 1A (GST collected on bookings) − 1B (GST credits on supplies) = the figure to remit each quarter.

For nightly-rate calculations, the GST calculator on this site handles both directions in one tool. The Reverse GST calculator is faster for splitting an inclusive total when you reconcile your monthly Airbnb payout against the BAS, and ASIC’s MoneySmart calculator is a free second opinion if you want one.

The 28-day rule (long-term accommodation concession)

A second wrinkle. If a guest in a commercial residential property stays for 28 continuous days or more, GST applies on half the normal inclusive price. The concession recognises that long-term commercial-residential stays sit between hotel and rent.

For most Airbnb hosts this is academic – the average stay is two or three nights – but operators of executive serviced apartments or workforce accommodation routinely use the concession.

Worked examples

A few scenarios in roughly the order they show up in real practice:

• Single-property residential host. Sarah rents her two-bedroom Newcastle unit on Airbnb for ten weekends across the year and earns $11,800. No GST applies, no GST registration required. She declares the income on her tax return and claims rental deductions in the usual way.
• High-earning residential host. James lets a beachfront house in Lorne for a 26-week summer season and earns $185,000. The income is residential rent, so it remains input-taxed. He doesn’t register for GST, doesn’t charge it and doesn’t claim credits on the new outdoor furniture from Bunnings.
• Serviced-apartment owner. Priya owns one apartment in a Sydney CBD complex managed by a hotel operator. Bookings, cleaning, linen and reception all go through the hotel. Her unit is part of a commercial residential operation. GST applies on her share of bookings, and she registers and lodges BAS quarterly.
• Borderline case: multi-property pool. Tom owns three apartments in coastal towns, all listed through a property management company that handles cleaning, linen and key collection. Whether his arrangement crosses into commercial residential depends on the specific contract terms with the manager and the level of integration with the other apartments in the pool. The ATO treats this as a question of fact, and a registered tax agent’s view is worth the consult fee.

The line between Sarah’s and Priya’s set-up is not always obvious from outside. Borderline arrangements like Tom’s almost always need professional advice before the first BAS.

What about Airbnb’s service fee?

Airbnb charges hosts a service fee on each booking. The platform issues invoices for those fees through its Australian-registered entity, with GST included where applicable. If you’re GST-registered (because the property is commercial residential), you can claim a GST credit on the platform fees. If you’re not registered, the GST on the fees is part of your cost base for income-tax purposes, like any other input-taxed supply.

Check the Airbnb invoice each month rather than relying on the dashboard summary. The platform’s tax treatment has changed several times since 2017, and the figure that ends up on your BAS depends on which entity is named on the invoice.

Final Thought

If you’re not sure which side of the residential vs commercial-residential line your property sits on, two steps will save you grief later. First, read the ATO’s Holiday apartments in commercial residential properties page – it’s the closest thing to a flowchart the ATO publishes for hosts. Second, get a registered tax agent to look at your specific arrangement before your first BAS, especially if you’ve registered for GST without confirming the input-taxed default doesn’t apply. We’ve seen hosts pay GST for two years before realising they shouldn’t have been registered, and the refund process is slower than you’d hope.
