Keep or Sell Australian Property When Moving Overseas?

The 11 pm question every departing property owner faces

Right, let us have the conversation you are actually having with yourself at 11 pm while the removalists’ quote sits open in another tab.

You own an investment property in Australia. You are moving overseas. And somewhere between booking the flights and cancelling the gym membership, a genuinely large financial question has quietly attached itself to your move: do you keep the place, or sell it before you go?

It feels like a property question. It is really a tax question wearing a property question’s clothes. Because the day your tax residency changes, the rules governing that property change with it, in ways that can cost or save you a great deal depending on what you do and, crucially, when you do it. This is one of those decisions where the difference between good advice and no advice can be measured in tens of thousands of dollars.

Here is what actually changes, where the traps are, and why the timing of a single signature can matter more than the sale price.

First, your rent changes tax treatment when your tax residency changes

One important distinction before we start: leaving Australia and ceasing Australian tax residency are not necessarily the same thing. Tax follows the residency answer, not the boarding pass.

Keep the property and rent it out as a foreign resident, and the rate treatment can change sharply. There is also a reporting trap worth knowing about, although that one applies whether you are an Australian resident or a foreign resident.

The rate is the part that actually turns on residency. As an Australian resident, your rental profit forms part of your taxable income, and Australian residents generally have access to the tax-free threshold. If you are a foreign resident for a full Australian income year, there is no tax-free threshold and the current foreign resident rates start at 30 per cent from the very first dollar. In the income year you actually leave, a part-year tax-free threshold can still apply, so the change is rarely as instant as your flight departure suggests. But make no mistake, the same rental profit that was being taxed gently, or not at all, while you lived here can end up attracting 30 cents in the dollar in a full year as a foreign resident. Nothing about the property changed. Only your residency did.

The second point is not a foreign-resident rule at all, but it catches plenty of property owners: you report the gross rent and claim whatever rental deductions you are actually entitled to separately. Not the tidy net figure your property manager transfers into your account after taking out their fees. It sounds like a technicality. But the Tax Office has long matched property-management and rental-bond data against what people declare, so a gross-rent mismatch is not especially hard to spot. A neat little net figure can become considerably less neat once somebody compares the data.

There is an upside worth knowing. If your property runs at a loss, as plenty of geared Australian properties do, leaving Australia does not automatically make that loss disappear. But how the loss can be used depends on your circumstances and, from the 2027-28 year, on Australia’s new residential-property loss rules as well. Some existing holdings are protected from those changes. Others are not. That is one more reason the keep-or-sell calculation needs to be done on the actual property rather than a rule of thumb found on the internet.

Do not forget the state tax bill

Federal income tax is not the only government department interested in the property once you move overseas.

Depending on where the property is located, moving out and renting it can change its land tax treatment. A principal-place-of-residence exemption may stop applying, and some states and territories impose additional surcharges on certain foreign or absentee owners. Depending on the jurisdiction and how the property is used, there can also be vacancy taxes, short-stay levies and other property-specific charges.

The awkward part is that these rules do not simply copy your Australian income-tax residency status. They can turn on citizenship, visa status, physical presence in Australia, the ownership structure, the particular state or territory and the date on which your status is tested. So being a foreign resident for Australian income tax does not automatically make you a foreign or absentee owner for state tax purposes, and the reverse assumption does not necessarily hold either.

These costs are not trivial. To give a sense of scale, foreign or absentee owner surcharges in the eastern states currently run at a few per cent of land value each year, sometimes with no tax-free threshold, on top of ordinary land tax. On a high-land-value property, that can quietly rearrange the whole keep-versus-sell sum. Before you move out or hand the keys to a tenant, check the land tax position and any foreign-owner, absentee-owner or other relevant property surcharges for the state or territory the property is in. Finding out after the assessment arrives is a particularly disappointing way to discover that the rental yield was not quite what your calculation spreadsheets promised.

The big one: the main residence exemption you think you have, but do not

This is where the numbers can get ugly, because a decision that looked harmless at the time can change the exemption entirely.

If the property was ever your home, you may be carrying an assumption that when you eventually sell, some or all of the gain will be shielded by the main residence exemption. For a foreign resident, that assumption is dangerous.

Under rules that have applied since the middle of 2020, a foreign resident who sells a former home is generally denied the main residence exemption entirely. Not reduced. Not apportioned for the years you actually lived there. Denied, in full, if you are a foreign resident at the time of the sale. You can have lived in the property as your genuine home for years and still lose the exemption because you are a foreign resident when the sale happens.

There is a narrow exception for certain life events within a limited window of foreign residency, but it is far narrower than most people hope, and building a plan around qualifying for it is not a plan. The safer assumption is that if you sell while a foreign resident, the exemption is gone.

Now sit with what that means for the keep-or-sell decision. A property you could have sold largely or entirely exempt as an Australian resident can suddenly lose the main residence exemption if you dispose of it as a foreign resident. That does not necessarily make every dollar of the gain taxable, because other capital gains rules, cost base adjustments and losses can still affect the final number. But the exemption you were relying on may simply be gone, because of your residency status on one particular date.

The date that can matter more than the price: when is the sale actually made?

This is the part where good advice can earn its keep.

For an ordinary property sale, capital gains tax generally turns on when the contract is entered into, not when settlement happens. That distinction sounds academic until your Australian tax residency is changing at about the same time, because your residency status is assessed at that moment, not at settlement weeks later.

A small difference in contract timing can materially change whether the main residence exemption is available. The catch is that you first need the residency date to be right, then the property history, then the contract timing, and guessing any one of those can turn a clever strategy into an expensive one. The gap between contract and settlement can be weeks. The gap between resident and foreign resident can be a single day.

That is as far as the general rule should take you. Check the sequence before the contract is entered into. Afterwards, tax planning has an annoying habit of becoming tax archaeology, and this is one of the conversations worth having before anything is signed.

The withholding surprise at settlement

Even where selling is the right call, there is a mechanism that catches foreign residents off guard at the very end of the process.

When Australian property is sold, the buyer may be required to withhold an amount and send it to the Tax Office unless the seller hands over the right paperwork before settlement. Since the start of 2025, the withholding rate has been 15 per cent and the old threshold that used to exempt lower-value properties is gone, so it can apply to essentially any sale. For an Australian resident vendor, a clearance certificate obtained in time prevents it. For a foreign resident, the position is different, and a meaningful chunk of your sale proceeds can be held back and sent to the Tax Office at settlement, to be sorted out later when you lodge.

It is not an extra tax. It is an amount withheld in advance and generally credited against your eventual Australian tax liability. But if you were not expecting it, discovering at settlement that a substantial amount of your sale proceeds has been redirected to Canberra is an unpleasant surprise, and it is worth knowing how the withholding works, and how any excess comes back, before you list rather than after.

The rule changes coming in 2027 belong in this decision

There is one more date anyone weighing up a long-term hold should have firmly in view.

From 1 July 2027, Australia’s capital gains rules change under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026. For many gains, the familiar 50 per cent capital gains discount gives way to a new regime involving inflation-based indexation, with transitional rules dealing with gains built up before the change.

For expatriates, there is an extra wrinkle that matters a great deal here. Your residency history after the new regime begins can determine whether that indexation is available to you at all, because the new treatment can be denied where you were a foreign resident or temporary resident during the relevant period. Further rules dealing with people whose residency changes are still being finalised, so this is an area where today’s spreadsheet can age quickly.

There is also a separate change to residential-property losses from the 2027-28 year. For some investors in established residential property, excess rental deductions will be quarantined rather than available against unrelated income, while many existing holdings are protected from that change.

You do not need the transitional calculations here. You do need to know that holding beyond 1 July 2027 can change both the tax treatment of the eventual capital gain and, for some properties, the tax treatment while you own it. That belongs squarely in the keep-versus-sell model.

So which is it: keep, or sell?

You will have noticed I have not told you. That is not evasion. It is because the honest answer is that it depends, and the things it depends on are exactly the things worth paying to get right.

The genuine decision turns on a handful of variables that interact: how much of your eventual gain is exposed once the main residence exemption is off the table, what your rental return looks like after Australian tax, land tax and any applicable state surcharges, whether and when you expect to return to Australia, how the 2027 changes affect your timeline, what the property is likely to do in value, and how your new country taxes the rent and eventual gain. Move the residency date or the contract date and several of those answers move with it.

That is a model, not a rule of thumb, and it is genuinely worth building before you decide. The useful work happens while the residency date, contract timing and ownership decision are still choices. Leave it until afterwards and the exercise changes from planning what should happen to calculating the consequences of what already happened.

The mistakes we see, so you can sidestep a few

A short field guide to the expensive ones.

• Treating the day you fly out as automatically being the day your Australian tax residency ends.
• Assuming the main residence exemption will still protect a former home sold as a foreign resident.
• Reporting the net amount from the property manager instead of gross rent with separate deductions.
• Entering into a sale contract without first checking the residency position.
• Being blindsided at settlement by withholding you did not know applied.
• Forgetting that turning your former home into a rental can also change its state land tax treatment.
• And modelling the Australian tax while quietly pretending the country you are moving to has no interest in your Australian property, when it may well, subject to any treaty.

None of these is especially exotic. That is rather the problem.

The short version

Keeping or selling an Australian investment property when you move overseas is not really a property decision. It is a tax decision with a property attached.

Your Australian rental income can be taxed differently once your residency changes, although the income year you leave has its own part-year rules. A foreign-resident sale can wipe out the main residence exemption you were expecting. The contract date can be critical. Settlement withholding can divert a substantial amount of the sale proceeds unless the right paperwork is in place. And from 2027, both the capital gains regime and the treatment of some residential-property losses change.

Those rules all collide with your residency dates and your particular property history. The useful work happens while you still have choices. Once the contract is signed, the menu becomes considerably shorter.

Frequently asked questions

Do I pay more tax on my rental income once I move overseas?

Often, yes, but the year you leave needs a little care. For a full income year as a foreign resident, there is no Australian tax-free threshold and the current foreign resident rates start at 30 per cent. If your residency changes part-way through an income year, a part-year tax-free threshold can still apply. You must still report gross rent and claim allowable deductions separately, and your new country may also tax the same rental income, subject to any treaty. The overall answer depends on your residency dates, deductions and destination country.

Will I lose the main residence exemption on my former home?

If you sell while you are a foreign resident, you generally lose the main residence exemption entirely on that sale, even for the years the property was genuinely your home. This has applied since the middle of 2020. A narrow exception exists for certain life events within a limited period, but it is much more limited than people expect. Because the exemption can turn on your residency status when the disposal contract is entered into, sale timing can be critical and should be reviewed before anything is signed.

Does it matter whether I sell before or after I leave Australia?

Very much. For capital gains tax, an ordinary property sale is generally treated as happening when the disposal contract is entered into, rather than when settlement occurs. Your residency status at that point can materially affect the tax outcome, including whether the main residence exemption is available. The contract date therefore needs to be tested against your actual residency position before the sale proceeds. Once the contract exists, some of the useful planning choices no longer do.

What is the 15 per cent foreign resident withholding?

When Australian property is sold, the buyer is generally required to withhold at the 15 per cent rate and pay the amount to the Tax Office unless the seller provides the right paperwork before settlement. Since the start of 2025, there is no minimum property-value threshold, so it can apply to most sales. It is not an extra tax. The amount withheld is generally claimed as a credit in your Australian tax return, with any excess potentially refunded after assessment. Managing it correctly, and recovering any excess, is worth planning for before you sell.

Should I just keep the property and sell it when I move back to Australia?

Sometimes that is a sensible strategy, but coming home is not a tax reset button. If you are an Australian resident when you sell, the special foreign-resident restriction on the main residence exemption no longer applies. You still need to satisfy the ordinary main-residence rules, though, and your period overseas can continue to affect other capital gains outcomes. From 1 July 2027, residency history can also affect whether the new indexation regime is available. So returning before the sale may materially improve the answer. It does not automatically recreate every concession you would have had if you had never left.

How do the 2027 capital gains tax changes affect this?

From 1 July 2027, Australia’s capital gains system changes materially. For many gains, the existing 50 per cent discount gives way to a new indexation-based regime, with transitional rules for assets already held when the change occurs. Expatriates need particular care, because residency history can determine whether indexation is available at all, and further rules for people whose residency changes are still being finalised. The same reform package also changes how some residential-property losses are treated from the 2027-28 year. For a property you might hold for several more years, those are not side issues. They belong in the keep-versus-sell calculation.
