Ceasing to be an Australian Resident: A Guide to CGT Event I1 in 2026
- 9 hours ago
- 9 min read
When an individual or company stops being an Australian resident for tax purposes, a specific and often unexpected tax rule is triggered: Capital Gains Tax (CGT) Event I1. This event can have significant financial implications, yet many individuals are unaware of its existence until they are in the process of moving overseas.
Essentially, CGT Event I1 functions as a form of 'exit tax'. The Australian Taxation Office (ATO) treats you as if you have disposed of certain assets for their market value on the day your tax residency ceases, an action known as a 'deemed disposal'. This rule applies to your worldwide assets that are not classified as 'Taxable Australian Property' (TAP), potentially creating a tax liability based on unrealised gains. Navigating the rules for the FY 2025–26 requires a clear understanding of which assets are affected and the compliance steps involved.
At Baron Tax & Accounting, our experience with clients in Brisbane shows that a primary point of confusion is distinguishing which assets are captured by this event. It is essential to differentiate between non-TAP assets, such as international shares or cryptocurrency, and Taxable Australian Property like Australian real estate, as they are treated very differently under the law.
What Triggers CGT Event I1?
CGT Event I1 is specifically designed to apply to assets that will no longer fall within Australia's tax jurisdiction once an individual or company becomes a non-resident. These are referred to as non-Taxable Australian Property (non-TAP) assets.
Key points to understand are:
Trigger Date: The event occurs at the precise moment you stop being an Australian resident for tax purposes.
Affected Assets: This rule commonly applies to assets like shares in foreign companies, units in overseas trusts, cryptocurrency, and collectibles held outside Australia.
Excluded Assets: It does not apply to Taxable Australian Property (TAP). These assets, such as a direct interest in Australian real estate, remain subject to Australian CGT regardless of your residency status.
Calculating the Deemed Gain or Loss
The primary compliance task is to calculate the capital gain or loss. This involves determining the market value of each affected asset on the exact date your residency status changes. The capital gain or loss is the difference between this market value and the asset's original cost base. For a detailed guide, you can learn more about how capital gains tax is calculated in Australia.
For example, a professional from Brisbane moving to Singapore with a portfolio of US-listed shares would need to obtain a market valuation for those shares on their day of departure to calculate the 'deemed' capital gain. This gain or loss must then be reported in their final Australian tax return for that income year. In more complex situations, individuals may choose to have their tax return reviewed by a registered tax agent to ensure accuracy and compliance.
How to Determine Your Tax Residency Status
Before CGT Event I1 becomes a factor, the foundational question is establishing your residency status. Your tax residency is not determined by your citizenship or visa but is a 'question of fact' based on your specific circumstances.
The ATO uses four tests to determine residency. You only need to satisfy one of these tests to be considered an Australian tax resident. The day you cease to meet all four tests is the date your residency ends, which in turn triggers CGT Event I1.
The Four Tests of Tax Residency
The resides test is the primary test. If you do not meet this, the ATO applies three statutory tests.
The Resides Test: This is an overall assessment of your circumstances. The ATO considers factors such as your physical presence, intention and purpose, family and business ties, and the location of your assets to form a general conclusion about where you "reside".
The Domicile Test: If your permanent home—your 'domicile'—is in Australia, you are considered a resident. The only exception is if you can prove to the ATO that you have established a permanent home elsewhere.
The 183-Day Test: You are generally considered a resident if you are physically present in Australia for more than half the income year (183 days or more), consecutively or intermittently. This test does not apply if you can establish that your usual place of abode is outside Australia and you do not intend to take up residence here.
The Commonwealth Superannuation Test: This specific test applies to Australian government employees working overseas who are members of the Public Sector Superannuation Scheme (PSS) or the Commonwealth Superannuation Scheme (CSS). They, along with their spouse and children under 16, are deemed to be Australian residents.
A Practical Brisbane Example
Consider a data scientist who has lived and worked in Brisbane for several years. She accepts a long-term role in Canada, sells her vehicle, ends her lease on an apartment in Fortitude Valley, and moves her personal belongings overseas.
By severing her primary ties to Brisbane and establishing a new life and home in Canada, she would likely cease to be an Australian resident from her date of departure. It is this combination of actions and intentions that determines the exact date for CGT Event I1. If you are planning a similar move, understanding the nuances of residency and international tax matters is a critical preparatory step.
The Two Choices Following a Deemed Disposal
When you cease to be an Australian tax resident and CGT Event I1 occurs, you are presented with a critical choice. You can either accept the default position and pay tax on the deemed disposal, or you can make a formal election to disregard it. This decision has significant long-term financial consequences.
The core process is summarised in the diagram below:

Path 1: Accept Path 2: Elect to Result
Deemed Disposal Disregard Disposal
(Pay CGT now) (Defer CGT)Path 1: Accept the Deemed Disposal (The Default Option)
This is the standard approach. You calculate the capital gain or loss on your non-TAP assets and declare it in your Australian tax return for the year you became a non-resident. A key benefit is that if you held the assets for more than 12 months as a resident, the 50% CGT discount is often available to reduce the taxable gain. This creates a clean financial break, as those assets are then free from any future Australian CGT.
Path 2: Make an Election to Disregard the Disposal
Alternatively, you can formally choose to disregard the deemed disposal. By making this election, you do not calculate a capital gain or loss upon leaving. Instead, the relevant assets are reclassified and treated as if they have become Taxable Australian Property. This means they remain within Australia's tax system, and you will be liable for CGT when you eventually sell them, regardless of where you are living. This option defers the tax liability but adds long-term compliance obligations.
Comparing the Deemed Disposal Paths
The decision between these paths requires careful consideration of your immediate financial position, the growth potential of your assets, and the tax laws of your new country of residence. For example, your obligations will differ depending on your destination, such as the specific tax obligations for digital nomads in Thailand.
Feature | Path 1: Accept Deemed Disposal | Path 2: Elect to Disregard |
|---|---|---|
Immediate Tax | Capital gain/loss is calculated and reported in your final Australian tax return. | No immediate tax is payable on these assets when you leave. |
Asset Status | Assets become free from any future Australian CGT. | Assets are treated as Taxable Australian Property (TAP). |
Future Tax Event | No further Australian CGT applies upon a future sale. | Australian CGT will apply when the asset is eventually sold. |
CGT Discount | The 50% CGT discount is often available if held for >12 months as a resident. | The CGT discount may be pro-rated, reduced, or unavailable upon future sale. |
Complexity | Creates a clean financial separation from Australia for these assets. | Adds a layer of long-term Australian tax compliance. |
If you own assets like a former home that has been used to produce income, the rules can become more complex. It is useful to understand how provisions like the main residence exemption 6-year rule works might interact with your situation. The election to disregard the disposal is binding and should be made based on a thorough analysis of your personal circumstances.
Key Exemptions and Special Conditions
While the deemed disposal rule is broad, certain exemptions can modify your CGT position when you cease residency. Understanding these is crucial for accurate tax planning.
Pre-CGT Assets: If you acquired an asset before the introduction of Capital Gains Tax on 20 September 1985, it is generally exempt from CGT. These assets are not subject to the deemed disposal rule.
Temporary Residents: CGT Event I1 does not generally apply to temporary residents when they leave Australia. Temporary residents are typically only subject to Australian CGT on their Taxable Australian Property, so their other worldwide assets were never subject to Australian CGT in the first place.
The Main Residence Exemption
The main residence exemption is one of the most significant tax concessions, but its application for non-residents has changed. A key rule change means that for properties sold after 30 June 2020, foreign residents at the time of sale generally lose access to the main residence exemption. This applies even if the property was your principal place of residence for many years while you were an Australian resident.
The "Life Events Test" Exception
A limited exception to this rule is the "life events test". This allows a foreign resident to claim the main residence exemption if they have been a foreign resident for a continuous period of six years or less at the time of sale, and one of the following life events occurred:
You, your spouse, or your child under 18 has a terminal medical condition.
Your spouse or your child under 18 passes away.
The sale of the property is part of a formal divorce or separation settlement.
This makes timing critical for homeowners in cities like Brisbane planning a permanent move overseas. Information on how residency affects your CGT obligations can be found directly from the ATO.
Compliance and Reporting Obligations
Managing your obligations for CGT Event I1 requires diligent record-keeping and timely reporting.
How to Report to the ATO
You must report the capital gain or loss from CGT Event I1 in your Australian income tax return for the financial year in which you ceased to be a resident. This applies whether you have a net gain or a net loss. Lodgement can be completed directly through the ATO's online services via myGov. Alternatively, some individuals use structured online tax return services where document submission and review can be completed without attending an office.
Foreign Resident Capital Gains Withholding (FRCGW)
If you later sell Taxable Australian Property (such as real estate), you must be aware of the Foreign Resident Capital Gains Withholding (FRCGW) rules. The FRCGW rate is 15% of the purchase price. The purchaser is required to withhold this amount and pay it to the ATO unless the vendor provides a clearance certificate.
To prevent this withholding, you must apply to the ATO for a clearance certificate before the property settlement. Each vendor on the title must apply for their own certificate. Applications are submitted online, and processing can take several weeks. Given the potential delays, using a tax agent to manage the application for a clearance certificate for CGT can help ensure a smooth transaction.
Record-Keeping Essentials
The burden of proof rests with you to substantiate the figures in your tax return. You must maintain detailed records, including:
Cost Base Evidence: Documents showing the original purchase price and any associated costs for each asset.
Market Valuations: Formal reports from a qualified valuer or other defensible data to support the market value of each asset on your residency cessation date.
Election Documents: If you choose to disregard the deemed disposal, a formal record of this election should be kept with your tax files.
Digitising and securely storing these documents before moving abroad is a practical measure. If you are preparing to depart, our guide to lodging your tax return before leaving Australia may be useful.
Summary
Core Rule: When you cease being an Australian tax resident, CGT Event I1 triggers a 'deemed disposal' of your non-TAP assets at their market value on that date.
Key Choice: You can either report the capital gain/loss in your final tax return (and potentially use the 50% CGT discount) or elect to disregard the event, which treats the assets as Taxable Australian Property and defers the tax liability.
Main Residence: The main residence exemption is generally unavailable to foreign residents for properties sold after 30 June 2020, unless a strict 'life events test' is met.
Compliance: You must report the event in your tax return for the year you cease residency. Strong record-keeping for valuations and cost base is essential.
Brisbane Context: For those leaving Brisbane, careful planning is needed to manage the CGT implications on both local property and worldwide investment portfolios.
