TL;DR
- Australian tax residents who hold an asset for 12 or more months qualify for the 50% CGT discount, effectively halving the taxable gain.
- Non-residents receive no discount; 100% of the capital gain is assessed at the applicable rate.
- If you owned an asset across both resident and non-resident periods, only the gain accrued during your resident period qualifies for the discount.
- The 12-month holding period is counted from acquisition to settlement and is independent of your residency status during that time.
- Selling investment assets before you formally become non-resident is one of the most impactful CGT planning moves available to departing expats.
What Is the 50% CGT Discount and Why Does It Matter for Expats?
The 50% CGT discount is a concession in Australian tax law that allows individuals who are Australian tax residents to include only 50% of a capital gain in their assessable income, provided they held the asset for at least 12 months before disposal.
For most investors, this concession operates quietly in the background. For expats, it is a pressure point, because residency status at the time of sale is a hard gate. You either qualify entirely (as a resident) or you do not qualify at all (as a non-resident).
Consider the numbers at a high level:
| Scenario | Capital Gain | Taxable Amount | Effective Outcome |
|---|---|---|---|
| Australian tax resident (held 12+ months) | $500,000 | $250,000 | Discount applied; significantly reduced bill |
| Non-resident at time of sale | $500,000 | $500,000 | No discount; full gain taxable |
At the top marginal rate, the difference in tax payable between these two scenarios can exceed $100,000 on a single property sale. This is why Australian expats who own investment property need to treat the 50% discount not as a technicality, but as a material planning variable.
What Are the Two Conditions That Must Both Be Met?
The 50% CGT discount has two non-negotiable requirements that must both be satisfied at the time of disposal:
- You must be an Australian tax resident at the time of the sale. Residency is assessed at the date of the CGT event (typically, the date of the contract or settlement, depending on the asset type). If you have become a non-resident before that date, the discount is unavailable.
- You must have held the asset for at least 12 months. The ATO counts the holding period from the date of acquisition to the date of the CGT event. An asset held for 11 months and 29 days does not qualify. An asset held for exactly 12 months does.
How Does the 12-Month Holding Period Actually Work?
The 12-month holding period is a precise clock, not an approximation. The ATO counts from the acquisition date (date of purchase contract or date asset was acquired) through to the CGT event date (typically the date of the sale contract for property).
Settlement date is not the same as contract date for this calculation. For investment property, the CGT event generally occurs at the date of the contract, not when settlement completes weeks or months later. This distinction is important: if your contract date falls before you have held the asset for 12 months, you miss the threshold, even if settlement happens after.
Practical implications:
- If you purchased an investment property with a contract date of 15 March 2025, the 12-month threshold is reached on 15 March 2026, not before.
- Signing a sale contract on 14 March 2026, even with a settlement date weeks later, would not qualify.
- The holding period counts regardless of your residency status during that time. Six months as a non-resident plus six months as a resident equals a total 12-month holding period that satisfies the time requirement.
What Happens When You Own an Asset Across Both Resident and Non-Resident Periods?
This is the scenario that catches the most expats off guard, and it is one of the areas where generalist accountants most frequently produce incorrect outcomes.
If you owned an asset while you were an Australian tax resident and then became a non-resident (or vice versa), the 50% discount does not simply apply to the whole gain or disappear entirely. It is apportioned.
The capital gain is split into two components:
- Gain accrued during Australian tax resident periods: Eligible for the 50% discount (provided the 12-month holding period is also met).
- Gain accrued during non-resident periods: Taxed at 100%, with no discount available.
The apportionment is typically calculated on a time basis, though the ATO may accept other reasonable methods where the time-based approach produces a distorted result. The practical implication: a long holding period as a non-resident before becoming resident again does not simply dilute; the non-resident portion of the gain remains fully assessable.
This apportionment rule means that even if you ultimately sell as a tax resident, years spent overseas as a non-resident can leave a significant taxable component untouched by the discount.
Why Is Departure Timing One of the Most Important CGT Decisions an Expat Makes?
For Australian expats who own investment property, the decision of when to become non-resident for tax purposes and when to sell an asset are not independent decisions. They interact directly, and the sequencing matters enormously.
The cleanest CGT outcome for an investment asset is achieved when you:
- Sell the asset after holding it for 12 or more months, and
- Sell while you are still an Australian tax resident.
For expats preparing to move overseas, selling an investment property before the date of non-residency locks in the 50% discount on the entire gain (subject to the 12-month rule). Waiting until after departure removes that discount permanently for any gain accrued post-departure.
It is also worth noting that non-residents selling Australian property are subject to the Foreign Resident Capital Gains Withholding (FRCGW) regime. As of 1 January 2025, the withholding rate is 12.5% on properties above the relevant threshold. This withholding is not a final tax, but it creates a cash flow obligation at settlement that can catch expats off guard if not planned for.
What About Your Home? Does the 50% Discount Apply to the Main Residence?
No, and this is a common point of confusion. The main residence exemption and the 50% CGT discount are separate concessions that apply to different types of assets.
- Main residence exemption: Applies to your primary home (the property you live in as your main residence). If fully eligible, the entire gain is exempt from CGT, not just 50%.
- 50% CGT discount: Applies to investment assets (investment properties, shares, managed funds, and other CGT assets) where you have held the asset for 12 or more months as a tax resident.
For expats, the main residence exemption has its own complex residency restrictions. Non-residents face limitations on accessing the main residence exemption for periods they were non-resident, which is a separate but equally important planning topic.
Frequently Asked Questions
Yes. The 50% CGT discount applies to any CGT asset held by an Australian tax resident for 12 or more months, including Australian shares, ETFs, and managed fund units. The same residency-at-time-of-sale rule applies.
No. Your home (main residence) is covered by the main residence exemption, which can exempt the entire gain if fully eligible. The 50% discount applies to investment assets, not your primary residence.
The discount applies only to the portion of the gain accrued during your Australian tax resident periods. Gain accrued while you were a non-resident is assessed at 100%, even if you sell years later as a resident.
Yes. The 12-month holding period is independent of residency. If you held an asset for six months as a non-resident and a further six months as a resident (totalling 12 months), the time requirement is met. However, the discount itself only applies to the resident-period portion of the gain.
Only on the portion of the gain accrued while you were a tax resident. Gain that accrued during your non-resident period is not eligible for the discount, regardless of your residency at the time of sale. The apportionment rules apply.
ODIN Tax identifies assets approaching the 12-month mark and flags them in the context of a client’s residency timeline. For expats preparing to depart Australia, ODIN Tax advises on the timing of property sales to maximise access to the 50% discount before non-residency takes effect. This kind of integrated planning, coordinated with mortgage and settlement timelines, is what ODIN Tax’s Expat Strategy Assessments are designed to deliver.
Generally, no. The 50% discount is available to individuals and certain trusts, but only where the beneficiary or individual is an Australian tax resident at the relevant time. Structures do not provide a workaround for the residency requirement. Anyone considering CGT through a trust or company structure should seek advice specific to their arrangement.
