What Happens to the 50% CGT Discount When You Become an Australian Non-Resident – And Why the Timing of Your Sale Matters

June 15, 2026
50% CGT discount non-residents

 

When you become an Australian non-resident for tax purposes, you lose access to the 50% capital gains tax (CGT) discount on any capital gain that accrues after the date you stopped being a resident. The ATO does not apply the discount to the entire gain on an asset you sell as a non-resident – it apportions it. If you sell at the wrong time, this change in status can cost you a substantial, and entirely avoidable, portion of your proceeds.

TL;DR – Key Takeaways

  • Non-residents cannot access the 50% CGT discount on gains that accrue during their period of non-residency.
  • The ATO uses a market-value uplift (or time-based apportionment) at the date you become a non-resident to separate the resident and non-resident portions of the gain.
  • Selling before you formally become a non-resident – while still an Australian tax resident – preserves the full discount if the asset has been held for more than 12 months.
  • The 15% Foreign Resident CGT Withholding (FRCGW) regime adds a cash-flow complication on top of the discount issue for property transactions.
  • Getting the timing wrong by even a few weeks can shift tens of thousands of dollars in tax liability.
About the Author: This article is produced by the team at ODIN Tax, Australia’s specialist tax agent practice for expats and non-residents, led by Tax Director Pau Lam, who brings over 10 years of dedicated experience in Australian expat tax – including hundreds of CGT assessments for clients selling Australian property from overseas.

What Is the 50% CGT Discount and Who Can Use It?

The 50% CGT discount is a concession available to Australian tax residents who have held a CGT asset – most commonly property or shares – for more than 12 months before disposing of it. Rather than paying tax on the full capital gain, a resident individual can reduce that gain by half before applying their marginal tax rate.

For non-residents, the position is materially different. Under current ATO rules, the 50% discount is not available on any portion of a capital gain that accrues during a period of non-residency. The critical word is “accrues” – it is not simply about your residency status on the day of sale. It is about when the gain was generated.

How Does the ATO Apportion the Gain Between Resident and Non-Resident Periods?

When a non-resident sells an asset they originally acquired as a resident, the ATO requires the total capital gain to be split into two portions:

  • Resident-period gain: The gain that accrued while you were an Australian tax resident. This portion retains access to the 50% discount (subject to the 12-month holding rule).
  • Non-resident-period gain: The gain that accrued from the date you ceased being a resident to the date of sale. This portion receives no discount and is taxed in full at non-resident marginal rates.

The ATO’s preferred method for this split is to establish the market value of the asset at the date of departure – the point you became a non-resident. The gain up to that date is the resident-period gain; the gain from that date forward is the non-resident-period gain.

Why Does the Timing of Your Sale Matter So Much?

Consider two scenarios involving the same property, the same purchase price, and the same eventual sale price. In Scenario A, the seller disposes of the property before leaving Australia – while still an Australian tax resident. In Scenario B, the seller delays the sale until after relocating overseas.

In Scenario A, the entire gain is a resident-period gain. The 50% discount applies, and the taxable gain is halved. In Scenario B, only a portion of the gain attracts the discount. The longer the property is held after departure, the greater the non-resident-period gain, and the higher the overall tax bill.

This is not a marginal difference. On a property with a substantial capital gain, the additional tax from losing even a portion of the 50% discount can run into tens of thousands of dollars. Timing the sale to occur before departure – where practically possible – is one of the most direct levers available to reduce CGT exposure.

What Is the Deemed Disposal Rule and When Does It Apply?

There is a related CGT rule that applies at the moment you become a non-resident, known as the deemed disposal rule (or “deemed CGT event”). When you cease being an Australian tax resident, the ATO treats you as having disposed of certain assets – notably assets that are not “taxable Australian property” (TAP) – at their market value on the date of departure.

Importantly, Australian real property (and property-related interests) qualifies as taxable Australian property and is therefore excluded from the deemed disposal rule. This means:

  • Australian real estate is not subject to deemed disposal on departure.
  • It remains within the Australian tax net regardless of where you live.
  • The CGT discount apportionment described above applies when the property is eventually sold.

By contrast, Australian shares in non-listed companies or foreign assets may trigger the deemed disposal at departure. Each asset class needs to be assessed separately.

How Does Foreign Resident CGT Withholding Add to the Complexity?

Beyond the discount question, non-residents selling Australian property face an additional compliance layer: Foreign Resident CGT Withholding (FRCGW). Under this regime, the purchaser of Australian property from a foreign resident is required to withhold a portion of the purchase price and remit it directly to the ATO at settlement.

Key points about FRCGW:

  • The withholding is applied to properties above the relevant threshold under current ATO rules.
  • Withholding is not a final tax – it is a prepayment credited against your assessed CGT liability when you lodge your return.
  • If your actual CGT liability is lower than the amount withheld, you receive a refund. If it is higher, you pay the shortfall.
  • Sellers can apply for a variation to the withholding rate if their actual liability differs significantly from the default rate.

FRCGW does not change how the discount apportionment works – but it does mean cash is tied up at settlement, which has real implications for property chains and refinancing.

Frequently Asked Questions

If I owned the property before I left Australia, can I still claim any CGT discount? Yes. The resident-period portion of your gain – the gain that accrued while you were an Australian tax resident – can still attract the 50% discount, provided the total holding period exceeded 12 months. The discount is lost only on the non-resident-period portion.
What if I return to Australia and become a resident again before I sell? Resuming Australian tax residency does not retroactively restore the discount on gain that accrued during your non-resident period. The gain will still be apportioned, and the non-resident portion will not attract the discount.
How does the ATO determine the market value of the property at my departure date? Typically through a formal valuation by a qualified, independent property valuer. The ATO may scrutinise valuations, so professional documentation is important. The valuation date should correspond precisely to the date you ceased being an Australian tax resident.
Does a Double Tax Agreement protect me from Australian CGT? Generally, no. Most of Australia’s Double Tax Agreements preserve Australia’s taxing rights over Australian real property. DTAs are more relevant to income streams (such as rent or dividends) than to CGT on direct property disposals. Each DTA differs, so specific treaty analysis is required.
Can I avoid CGT entirely by using the main residence exemption as a non-resident? The main residence exemption for non-residents was significantly restricted by legislative changes. Non-residents disposing of their former main residence generally cannot access the full exemption unless specific transitional conditions apply. This is an area where professional advice is critical given the potential tax at stake.
Does the CGT discount apportionment apply to shares as well as property? Yes. The same apportionment principle applies to shares in Australian companies that qualify as taxable Australian property. The resident-period gain may attract the discount; the non-resident-period gain will not.
If I sell before I leave, do I still need to lodge an Australian tax return? Yes. A capital gain realised during the financial year you depart Australia must be reported in your Australian tax return for that year. You would lodge as an Australian resident for the portion of the year before departure.
