Here at sansdesk, nothing warms our hearts more than hearing about unique individuals enriching their own lives by facilitating the dreams of others. When we read Clio’s story on the Airbnb blog, we knew we had to reach out to hosts just like her and do our bit to make their life easier – sans desk.
While I have penned the post as a shout out to Airbnb hosts, the concepts could be applied in a more general sense to anyone seeking to rent out a part of their home, whether through Gumtree, Realestate.com.au, Flatmates.com.au and so on.
The tax issues raised in the post relate to hosts who:
- own their own home;
- live in it full time; and
- want to generate some dollars by putting up an identifiable area of their home for rent.
As a host, the three major tax considerations that you need to be aware of are:
- Rental income
- Rental expenses
- Capital gains tax
Let’s consider the implications of each in turn.
RENTAL INCOME
The main question hosts need to ask themselves here is whether a commercial amount of rent is being charged.
Generally, where a room is advertised for rent at market rates to the general public through Airbnb (or a similar online directory) the arrangement is likely to be at ‘arms-length’ and hosts would be required to declare their rental income.
RENTAL EXPENSES
Where the rental arrangement is at ‘arms-length’ and income is declared, hosts would be entitled to tax deductions for expenses incurred in deriving that rental income.
Expenses incurred by hosts can be split into three categories:
- Expenses that are directly associated with the rented area – deductible in full.
- Expenses that relate to shared areas – apportionment required.
- Expenses that relate to the host’s private area only – not deductible.
Depreciation on furniture purchased for use in the rented room is a good example of an expense that is directly associated with the rented area of the host’s home and would be deductible in full.
Some examples of other expenses that may be deductible in full include:
- commercial cleaning of a rented area;
- repairs and maintenance;
- professional photography for the listing; and
- host service fees charged by Airbnb.
Where there are expenses that relate to the entire property, apportionment is required. The ATO have indicated that floor space can be used as a general approach for apportioning expenses. This is best illustrated by way of an example:

FIGURE 1
Total floor space of the property = 790 sq. feet
Floor space of rented area = 190 sq. feet
Floor space of shared area = 380 sq. feet (shared equally between one host and one tenant)
Floor space of host’s private area = 220 sq. feet
In the above example, the total area of the property that could be apportioned to the tenant is 380 m2, being 100% of the rented room and 50% of the shared area. Therefore, it may be reasonable for hosts to include 380 / 790 (48%) of expenses that relate to the entire property as a deduction.
Some examples of expenses that relate to the entire property and may be deducted in this way include:
- mortgage interest;
- council rates;
- utilities; and
- insurance.
It is important to note that where capital works are undertaken in relation to the property, Division 43 capital works deductions are generally not available to hosts, as they are also using the property for their own residential accommodation.
Expenses that relate to shared areas can be apportioned based on access. In our example above, the one tenant and one host had equal access to shared areas, therefore the host could deduct 50% of these expenses.
Examples of expenses that relate to shared areas only and may be deductible in this way include: * depreciation on furniture and appliances located in shared areas; * internet; and * cable TV.
If a host’s rental expenses exceed their rental income, it may be possible for hosts to negatively gear their own home. This means that any excess of rental expenses over rental income can effectively be claimed as a tax deduction against the host’s other income such as their salary.
I would strongly recommend consulting a tax advisor if you are a host that is in this position, as where the rental arrangement is reviewed by the ATO and they determine that a non-commercial rate of rent (i.e. a lower than market rate) was being charged, they could limit your rental deductions to the extent that they exceed the amount of rental income received.
One final thing to note in relation to expenses is that they are only deductible where an area of the house is either actually rented out, or available for rent.
For example, where a room in the host’s home is only available for rent for 90 days a year, say, while a housemate is away, then only the portion of rental expenses that were incurred during that 90-day period would be deductible and further apportionment may be required.
In this example, it is not a requirement that the room is actually rented for the 90 day period for the host to be entitled to a deduction for rental expenses – having the room available for rent is sufficient. Therefore, even if no guests have booked a stay in the room during the 90 day vacancy period, if the room is advertised on Airbnb (or similar) as vacant and ready for occupancy, the host would remain entitled to deductions for rental expenses.
CAPITAL GAINS TAX
Broadly, the sale of an individual’s primary residence is CGT-free under the main residence exemption if:
- the dwelling was their main residence for the entire time they owned it;
- it was not used to produce assessable income.
However, as hosts are renting out a portion of their home on Airbnb, they are using a portion of it to produce assessable rental income and therefore would only be only eligible for a partial main residence exemption. This means that hosts may be taxed on a portion of any capital gain realized upon the sale of their main residence.
It is important to note that pre-CGT assets purchased prior to 20 September 1985 are not subject to CGT, regardless of whether they are used to derive rental income – hosts that purchased their home prior to this date can skip this section of the post altogether.
The below scenarios assume the following:
- The host purchased their home post 20 September 1985 (and therefore may be subject to CGT on the sale); and
- The host would have been eligible for the main residence exemption from the time that they purchased their home until the time that they started renting out a portion of their home.
A basic scenario would be one in which a host rented out the same part of their home from the time that they purchased it until the time that they sold it. In this case, the part of the home used to produce assessable income would be subject to CGT and the private portion of the home would be CGT free under the main residence exemption. As with expenses, an apportionment based on floor space may be used to determine the portion of the property that is subject to CGT.
A more common scenario may be where the host began renting out a part of their home some time after moving in. The calculations under this scenario can differ depending on whether the host first began using their home to produce assessable before or after 20 August 1996.
The reference ‘first used to produce assessable income’ would generally be the first time a host rented a part of their home out (whether on Airbnb or otherwise). However, if the host had previously used part of their home as a home office or workshop at some time in the past, it may actually be that time that the home was first used to produce assessable income.
Where the host first used their home to produce assessable income prior to 20 August 1996, they would need to calculate the portion of the ownership period in which they used the entire house for private purposes and the portion in which they were renting part of the house out. For example:
Purchased: 1 July 1991 (used 100% for private purposes)
First rented a portion of house: 1 July 1995 (30% of total floor space apportioned to tenant)
Sold: 1 July 2012
Total days house was owned:
7,671Total days portion was rented out:
6,210Gain on sale:
$100,000Calculation: 100,000 x 6,210/7,671 x 30% = $24,286 gross capital gain.
This gross capital gain could then be reduced further by either indexation or the general 50% CGT discount, as the property was held for more than 12 months.
Where the host first used their home to produce assessable income post 20 August 1996, the calculation is slightly different. The host would need to obtain a market valuation as at the date that the house was first used to produce assessable income, which is then taken to be their deemed cost base to be used in calculating any future capital gain. This valuation could come from a registered valuer or could be calculated by the host, however it is important to note that the ATO has the power to challenge valuations.
Purchased: 1 July 1991 (used 100% for private purposes)
First rented a portion of house: 1 July 1998 (30% of total floor space attributable to tenant)
Market value @ 1 July 1998: $200,000
Sold: 1 July 2012
Sale price: $500,000
Calculation: ($500,000 – $200,000) * 30% = $90,000 gross capital gain
This amount may be reduced further by either indexation or the general 50% CGT discount.
These two scenarios are relatively straightforward. Where different portions of the house were available for rent during the host’s ownership period, or where the entire house was rented during some periods and was used 100% for private purposes during other periods, the CGT calculations can become very complex.
FINAL THOUGHTS
Goods & Services Tax
Income from renting out part of a residential property is ‘input-taxed’. This means that hosts should not charge GST on the rent that they earn from guests.
Conversely, hosts cannot claim input tax credits for any rental expenses that they incur, but are entitled to claim the GST inclusive amount of any rental expenses as a tax deduction
PAYG instalments
If hosts report more than $2,000 of rental income on their latest lodged tax return, they may receive a letter from the ATO notifying them that they are required to begin making periodic PAYG instalments. These are essentially prepayments of tax that are offset against the host’s final tax liability at the end of the year upon lodging their tax return.

It is important to remember that every host’s individual situation is likely to be slightly different and while we have provided a general summary of the tax issues facing hosts, we strongly recommend hosts consult a tax advisor to obtain specific advice in relation to their particular situation.
