Australian Tax for Non-Residents: A Practical Guide to Taxation, CGT and Super Planning
By Symmetry Accounting & Tax Pty Ltd
When an individual becomes a non-resident for Australian tax purposes, their taxation position can change dramatically. The rules no longer operate in the same way as they do for Australian residents, and that can affect everything from employment and investment income to capital gains, property ownership and superannuation planning.
For clients with cross-border interests, understanding these rules is essential. From an accounting and business advisory perspective, the starting point is always the same: determine residency correctly, identify which income remains taxable in Australia, and then assess how concessions, withholding obligations and capital gains tax rules apply.
This area is particularly important for Australians moving overseas, foreign investors with Australian assets, and individuals with property, shares, managed funds or SMSF interests connected to Australia.
Why tax residency matters
Australian residents are generally taxed on their worldwide income. By contrast, non-residents are usually taxed only on income that has an Australian source. That difference has significant consequences.
A non-resident does not ordinarily access the tax-free threshold and may also lose access to certain tax offsets and capital gains concessions. In many cases, passive income such as interest, royalties and some dividends may be subject to withholding tax instead of the normal assessment process.
From a taxation planning viewpoint, residency status is not a minor detail. It drives how income is taxed, whether CGT applies, and how broader accounting, SMSF and business advisory strategies should be structured.
How Australian tax residency is assessed
Before any meaningful advice can be given, residency must be established. In broad terms, an individual is treated as an Australian tax resident if they satisfy any of the relevant residency tests. If none of those tests are met, they are generally treated as a non-resident.
1. The resides test
This is the primary test and focuses on whether the person is living in Australia in an ordinary and settled way. The analysis usually considers factors such as:
physical presence
family and social ties
work arrangements
asset ownership
routine and living habits
where the person’s home life is genuinely based.
No single factor determines the outcome on its own. A person may still be treated as an Australian resident even while spending substantial time overseas if Australia remains their real home base.
2. The domicile test
A person with an Australian domicile may continue to be treated as an Australian resident unless they have established a permanent place of abode outside Australia. This requires more than a short-term relocation or temporary overseas assignment.
The overall picture matters, including the intended duration of the move, living arrangements overseas, and whether the person has effectively severed residential ties with Australia.
3. The 183-day test
An individual present in Australia for 183 days or more in an income year may be treated as a resident unless it is clear that their usual place of abode is outside Australia and they do not intend to live here.
4. The Commonwealth superannuation fund test
Certain Commonwealth employees serving overseas, together with some family members, may remain Australian residents under specific superannuation-related rules.
How non-residents are taxed in Australia
Once a person is classified as a non-resident, Australian tax usually applies only to Australian-sourced income. Unlike residents, non-residents are generally taxed from the first dollar of taxable Australian income.
The following non-resident tax rates apply for Australian-sourced income:
from $0 to $135,000: 30%
from $135,001 to $190,000: $40,500 plus 37% of the excess over $135,000
above $190,000: $60,850 plus 45% of the excess over $190,000.
For accounting and taxation purposes, this means residency changes can materially alter cash flow, effective tax rates and year-end planning.
The role of double tax agreements
Where Australia has a double tax agreement with the other country, that agreement may modify the usual domestic tax outcome. These treaties can affect:
which country has taxing rights
whether withholding tax is reduced
how dual residency is resolved
whether certain income is taxed differently.
This is a major issue in cross-border taxation. Two clients with similar income profiles may face very different Australian outcomes depending on which country they move to and whether a treaty applies.
Withholding tax on passive income
Non-residents are often taxed through withholding mechanisms on certain forms of passive Australian income. According to the source article, the main treatments include:
Unfranked dividends: generally 30%, often reduced under a treaty
Fully franked dividends: generally no withholding, but franking credits are not refundable to non-residents
Interest: commonly 10%, though treaty relief may apply
Royalties: commonly 30%, often reduced by treaty
MIT distributions: generally 15% to 30%, depending on the recipient’s country status and applicable rules.
Where final withholding tax applies, that amount is typically the end of the Australian tax process for that income stream. In many cases, the income is not separately included in assessable income, and deductions cannot be applied against it in the usual way.
That distinction is important in both accounting compliance and business advisory work because it affects reporting, cash flow forecasting and the value of deductions.
Capital gains tax for non-residents
CGT treatment changes significantly once a person becomes a non-resident.
In general, non-residents are only subject to Australian CGT on taxable Australian property. This typically includes:
Australian real estate
certain interests in land-rich entities
business assets connected to an Australian permanent establishment.
Assets that are not taxable Australian property may fall outside the Australian CGT net, unless an election was made when the person ceased residency that keeps those assets within the system.
This is one of the most important areas in non-resident taxation because the timing of residency changes, asset disposals and elections can alter the final tax outcome substantially.
The 50% CGT discount
Non-residents cannot usually claim the standard 50% CGT discount for periods during which they were non-residents. In some cases, older assets may still qualify for partial relief under transitional rules, but the broad principle is that foreign residency limits access to the usual discount.
That makes capital gains planning particularly important before departure from Australia, especially where significant unrealised gains exist.
Main residence exemption: a major trap
One of the most misunderstood areas of taxation for non-residents is the loss of the main residence exemption.
If a person is a foreign resident when the CGT event occurs, they will generally not be entitled to the main residence exemption, even if the property was once their home and even if they were an Australian resident for part of the ownership period.
There is a limited exception where strict life event conditions are satisfied, but outside those narrow circumstances, the exemption is usually unavailable. This means a former home can become fully exposed to CGT if sold while the owner is a foreign resident.
From a business advisory and accounting standpoint, this is often an area where advance planning can prevent a very costly outcome.
Investment properties held by non-residents
Australian investment property remains highly relevant for non-residents because both the rental income and the eventual sale may still trigger Australian taxation consequences.
Rental income from Australian property remains assessable in Australia and is taxed at non-resident rates. Deductions such as interest, repairs, depreciation and other property-related outgoings are generally still available.
Where deductions exceed income, the resulting tax loss is usually carried forward and applied against future Australian assessable income. It does not ordinarily reduce foreign-source income.
On disposal, Australian real property remains within the CGT system. In practice, this means the gain may be fully taxable, subject to any limited discount entitlement and the main residence rules discussed above.
CGT planning when leaving Australia
When an individual stops being an Australian resident, certain non-taxable Australian property assets are treated as though they were disposed of at market value at that time. However, the taxpayer may choose to keep those assets within the Australian CGT regime instead.
That choice can have very different consequences:
crystallising the gain at departure may lock in the tax position and exclude future growth from Australian CGT
keeping the asset inside the regime may defer the immediate tax cost, but future growth may remain taxable in Australia.
The right approach depends on the asset profile, the expected growth trajectory, the timing of any disposal and the tax treatment in the person’s new country of residence.
This is exactly where integrated accounting, taxation and business advisory services add value, because the decision should never be made in isolation.
Deductible super contributions and SMSF considerations
A non-resident may still be able to make personal deductible super contributions if the ordinary contribution rules are satisfied. Where Australian assessable income exists, that deduction may help reduce taxable income.
That can be useful, for example, where a person has realised a taxable capital gain in Australia.
However, contributions do not reduce income that is subject to final withholding tax. In addition, some government super concessions are not available to non-residents.
Special care is also required where the individual is involved in an SMSF. Residency issues can create compliance risks for the fund itself, so SMSF members who move overseas should seek advice before making contributions or changing how the fund operates. This is one of the most sensitive overlap areas between taxation, superannuation and SMSF compliance.
What happens when the person returns to Australia?
When someone later becomes an Australian resident again, their non-taxable Australian property assets are generally treated as being acquired at market value when residency recommences. That market value becomes the new cost base for future Australian CGT purposes.
This reset can be very important because only later gains may then be taxed in Australia. However, taxable Australian property does not receive the same reset treatment, and prior elections may continue to affect the asset’s tax position.
Medicare levy and student loan obligations
Non-residents are generally not liable for Medicare levy or Medicare levy surcharge on non-resident income, although part-year resident situations can be more complex.
Student loan obligations are different. Australian HELP and HECS liabilities can continue even while a person lives overseas, with worldwide income still relevant to repayment obligations.
This is an area that is often missed in practical taxation advice and should not be overlooked.
Final thoughts
Australian tax rules for non-residents are highly specialised and can produce outcomes that differ sharply from the resident tax system. Residency status affects which income is taxed, how capital gains are measured, whether exemptions remain available, and how superannuation or SMSF strategies should be handled.
For individuals moving overseas, foreign residents with Australian assets, or families managing cross-border property and investment positions, early advice is critical. Sound accounting, careful taxation analysis and practical business advisory support can make a substantial difference to both compliance and long-term wealth outcomes.
