Selling Australian Property as an Expat? The Taxman Takes 15% at Settlement (Before You See a Cent)

Picture settlement day. You’ve sold the old place back in Australia, the contracts are done, and you’re mentally spending the proceeds. Then your conveyancer mentions, almost in passing, that 15% of the sale price isn’t coming to you. It’s going straight to the ATO.

Welcome to foreign resident capital gains withholding, one of the nastiest surprises in expat finance, and one that has caught out thousands of Australians overseas who simply didn’t know it existed. The rules have tightened twice since they began, and as of 1 January 2025 they are tougher than ever. So before you so much as call a real estate agent, read this.

What this withholding actually is

Foreign resident capital gains withholding (FRCGW for the acronym lovers) is the government’s way of making sure foreign residents can’t sell up Australian property and disappear overseas without settling their capital gains tax. The mechanism is brutally simple: the buyer is legally required to withhold a slice of the purchase price at settlement and send it directly to the ATO, before the seller gets the balance.

Note that carefully: it’s a slice of the price, not of your profit. The ATO grabs its security deposit first and sorts out what you actually owe later, when you lodge your return. If too much was withheld, you get the difference back as a refund. But in the meantime, it’s the ATO holding your money, not you.

The rules got much harsher on 1 January 2025

If you’ve read older articles about this (including, possibly, an older version of this very one), wipe the numbers from your memory, because they’ve all changed.

When the regime began in 2016, withholding was 10% and only applied to properties selling for $2 million or more. From 1 July 2017 it rose to 12.5% and the threshold dropped to $750,000. And from 1 January 2025, two changes landed together that catch almost everyone:

The rate increased to 15% of the sale price. And the threshold was abolished entirely. There is no longer any minimum property value: the rules now apply to every sale of Australian real estate by a foreign resident, whether it’s a $20 million harbourside mansion or a $300,000 unit in a regional town. The days of small sales slipping under a threshold are over.

What this means if you’re an expat seller

If you’re a foreign resident for tax purposes when you sell, the buyer must withhold 15% of the price and remit it to the ATO. You then lodge an Australian tax return for that year declaring the capital gain, and you claim a credit for the 15% already withheld. If your actual tax bill on the gain is less than the amount withheld (which it very often is, since the withholding is on the whole price, not the gain), the excess comes back to you as a refund after lodgment.

The sting is in the cash flow. On an $800,000 sale, that’s $120,000 parked with the ATO from settlement day until your return is processed, which could be many months later. If you were counting on the full proceeds to fund your next move, that gap can hurt. Plan for it.

The clearance certificate: how Australian residents avoid withholding entirely

Here’s the escape hatch, and it’s an important one. If you’re an Australian resident for tax purposes when you sell, you don’t have to suffer the withholding at all. You apply to the ATO for a clearance certificate and hand it to the buyer before settlement. Certificate in hand, the buyer withholds nothing and you receive the full proceeds.

Clearance certificates are free, valid for 12 months, and these days the ATO says most are issued within a few days, though it can take up to 28 days in trickier cases. The unmissable point: apply early. Apply the moment you decide to sell, not the week of settlement. If the certificate doesn’t reach the buyer in time, they are legally obliged to withhold the 15%, and chasing it back from the ATO afterwards is a slow, dull process you’d rather avoid.

Now for the catch that matters most to readers of this site: a clearance certificate certifies that you’re an Australian resident for tax purposes. If you’re a genuine non-resident expat, you generally won’t qualify for one, so the withholding will apply. This is exactly why your residency status at the time of sale is the single most important variable in the whole transaction.

Can’t get a certificate? You may still be able to vary the rate

If you can’t get a clearance certificate but the standard 15% overstates your actual tax liability (say your real capital gain is small, or you’re making a loss on the sale), you can apply to the ATO for a variation. A variation can reduce the withholding rate, sometimes all the way to nil, so the buyer holds back an amount closer to your true liability rather than a flat 15% of the price.

This is genuinely useful for expats selling at a modest gain or a loss, where 15% of the price would wildly exceed any tax actually owed. Like the clearance certificate, a variation must be applied for and approved before settlement, so once again: early, not late. Getting the variation amount right involves estimating your actual gain and liability, which is precisely the kind of calculation worth having a specialist check.

The bigger trap: the main residence exemption is gone for non-residents

The original version of this article promised a follow-up on the main residence exemption. Here’s the headline, because it’s the part that turns withholding from a cash-flow nuisance into a genuine financial blow.

Since 1 July 2020, foreign residents have generally lost the main residence exemption altogether. Sell your former Australian home while you’re a non-resident and the capital gain can be taxable all the way back to the date you bought it, not just the period you rented it out. The old six-year absence rule that many expats still rely on simply does not apply to a sale made while you’re a non-resident, except under a narrow “life events” test for those who’ve been non-resident for six years or less.

So the withholding is only the visible part. The real exposure is the capital gains tax bill underneath it, and for a former home, that bill can be eye-watering. The flip side is the planning opportunity: because both the exemption and your withholding position hinge on your residency at the time you sign the contract, the timing of a sale around a return to Australia can change the outcome by a six-figure sum. We dig into this in our Australian Expat Tax Changes – 2026 Budget Guide for Expats, which also covers proposed measures still working their way through Canberra.

The bottom line

Selling Australian property as an expat is not a decision to make on a whim from the other side of the world. The buyer will withhold 15% of the price unless you hold a clearance certificate (which generally means being an Australian resident at the time) or an approved variation. And lurking beneath the withholding is the far larger question of how much capital gains tax you actually owe, now that the main residence exemption has deserted non-residents. Get your residency, your timing and your paperwork sorted before you sign anything.

Tread your own path. Just don’t sign a sale contract on it without checking the tax map first.

Thinking of selling? Talk to us before you sign, not after.

The most expensive property mistakes we see aren’t made at settlement. They’re made the day someone signs a contract without realising what their residency status does to their tax bill. A short conversation beforehand can mean the difference between a clearance certificate and a 15% withholding, or between a modest tax bill and a catastrophic one on a former home.

Our specialist expatriate tax team handles exactly this: residency assessments, clearance certificates, rate variations and the capital gains calculations underneath them, for Aussie expats selling property from anywhere in the world.
