Foreign Income Reporting for Australian Expats
Australian expats ask us this question more than almost any other, what income do I actually need to declare?
The answer starts with a single prior question, one that many expats answer incorrectly. That question is: are you an Australian tax resident or not? Because the reporting obligations for a resident and a non-resident are fundamentally different, and getting the wrong answer to that first question cascades into errors across everything else.
Before you can work out your foreign income tax obligations as an Australian expat, you need to know your residency status under Australian tax law. That is where this guide begins.
The Fundamental Rule: Residency Determines Everything
Australian tax law draws a sharp line between residents and non-residents (also called foreign residents) for Australian income tax purposes.
These categories are not based on where you live, how long you have been away, or what passport you carry, although they are related to these issues. They are based on a series of legal tests detailed in section 6(1) of the Income Tax Assessment Act 1936, with additional guidance provided by the Australian Taxation Office (ATO) in Taxation Ruling TR 2023/1 Income Tax: Residency Tests For Individuals.
The rule that flows from that determination is simple in concept, however incredibly complex to apply:
- Tax residents (for Australian income tax purposes) are subject to taxation on their worldwide income. Every dollar earned from any source, in any country around the world.
- Non-residents (for Australian income tax purposes) are taxable only on their Australian-sourced income.
That distinction changes what you declare, which tax rates apply, and whether the tax-free threshold is available to you at all.
If you are not certain which category applies to you, read our guide to Australian tax residency for expats before going further. Nothing that follows is accurate unless your residency position is right.
Australian Tax Residents Living Overseas: Obligations for Tax on Worldwide Income
Here’s a belief that floats around expat communities like a bad rumour at a dinner party: “I pay tax in the country where I work, so I don’t owe anything in Australia.”
That’s not how it works. If you’re still an Australian tax resident, you owe tax on your worldwide income. Full stop. Paying tax somewhere else doesn’t necessarily make the Australian obligation disappear. It may give you a tax credit (we’ll get to that), but it doesn’t necessarily make the income invisible or non-reportable.
Let’s go through what counts.
As a resident, you must generally declare every dollar of income earned anywhere in the world. That is not a technicality or an edge case. It is the foundational rule.
Employment Income from Overseas
Your salary, wages, or contractor fees from an overseas employer are assessable in Australia. Unless a tax treaty applies (if it does, contact our team for assistance as the complexity increases dramatically), the fact that you pay income tax in another country does not make that income exempt – though it may entitle you to a foreign income tax offset, discussed further below.
Now, there’s an old piece of advice that still circulates, and it needs to be put to bed permanently. Some people (and, regrettably, some accountants) still tell expats that section 23AG of the Income Tax Assessment Act 1936 exempts overseas employment income. It used to. It doesn’t anymore. The general private-sector exemption was removed from 1 July 2009. What’s left is a narrow provision covering certain government and official development assistance roles. If someone tells you your overseas salary is “exempt,” ask them what year their textbook is from.
Foreign Investment Income
Interest from foreign bank accounts, dividends from foreign-listed shares, net rental income from overseas properties, and distributions from foreign trusts are all assessable for Australian tax residents. The worldwide income obligation does not have a carve-out for investment income just because the assets are sitting in another country. If you are a resident, the source of your income is largely irrelevant.
Interest from foreign bank accounts. Dividends from foreign-listed shares. Net rental income from overseas properties. Distributions from foreign trusts. All assessable for Australian tax residents. The worldwide income rule doesn’t have a carve-out for investment income just because the assets are sitting in another country. If you’re a resident, source is irrelevant
Foreign Pensions and Capital Gains
Foreign pension income is generally assessable for Australian residents, subject to the relevant double tax agreement (DTA). The treatment varies by DTA – under the Australia-UK agreement, for example, UK government service pensions are generally taxable only in the UK, while UK occupational pensions and the UK State Pension are generally assessable in your country of residence (for tax treaty purposes) i.e. Australia if you’re a tax resident of Australia. Read each agreement on its own terms; there is no blanket rule.
Capital gains on overseas assets are similarly assessable. If you sell shares, property, or other assets in Australia or overseas, any capital gain is subject to Australian CGT. A foreign income tax offset may be available for any foreign tax paid on the same gain.
Australian Non-Residents: Australian-Source Income Only
If you have broken Australian tax residency under the legal tests, your Australian obligations narrow considerably. You are only taxed on income that has its source in Australia.
What Counts as Australian-Source Income?
- Employment income from Australian work: If you physically perform services in Australia – even temporarily during a visit – that work has an Australian source. Where a tax treaty does not apply, this potentially catches short-term business visitors and expats working during periods back home.
- Rental income from Australian property: Net rental income from Australian real property is fully assessable. Allowable deductions reduce the net amount, but a return must be lodged regardless of the outcome of the rental arrangement (i.e. regardless of whether a profit or loss is made).
- Australian interest: Interest from Australian financial institutions is subject to 10% withholding tax for non-residents (reduced by applicable DTAs). If the correct amount has been withheld, you may not need to lodge a return if this is your sole Australian income source. If you have other Australian income in the same year, however, a return is required and all income must be included.
- Australian dividends: Unfranked dividends paid to non-residents generally incur a 30% withholding tax (although if a tax treaty applies, this reduces typically to 15% for most treaty countries). Fully franked dividends are not subject to withholding tax, and neither are they subject to income tax in the hands of a non-resident. Note however that non-residents do not receive a refund of the franking credit like Australian residents do. It is simply not available under the Australian imputation system.
- Capital gains on taxable Australian property: This is where the most unexpected tax bills arise for non-residents. “Taxable Australian property” (TAP) is defined in section 855-15 and section 855-20 of the Income Tax Assessment Act 1997. It covers direct interests in Australian real property, indirect interests in land-rich entities (broadly, companies or trusts where the majority of assets are Australian real property), and assets used in an Australian business through a permanent establishment. Capital gains on TAP are fully taxable in Australia for residents and non-residents alike. However the 50% CGT discount does not apply to non-residents on assets acquired – or that became TAP – on or after 8 May 2012. It does however apply for the period before that date that the asset was held. Where a person was eligible for the 50% before becoming a non-resident (or after recommencing residency), the 50% CGT discount is pro-rated to a lower percentage based on the period of non-residency compared to the total days held. For anyone selling Australian property held for many years, the reduction of that discount (and potentially its absence) materially increases the tax cost.

What Non-Residents Generally Don’t Owe Tax On
Non-residents do not pay Australian tax on foreign employment income, foreign rental income, foreign interest and dividends, or capital gains on assets that are not taxable Australian property. If you have broken residency cleanly and your Australian footprint is limited to non-TAP assets, your Australian tax exposure may be limited.
How to Convert Foreign Income to Australian Dollars
Every amount on your Australian tax return must be in Australian dollars. No exceptions, no shortcuts.
The ATO publishes annual average exchange rates for major currencies, and these are generally acceptable for salary and other regular income received throughout the year. For lump-sum amounts, like a one-off payment or sale proceeds, the spot rate on the date of receipt is more appropriate. For CGT calculations, the rate on each transaction date matters, not the date the money hits your Australian account (although that date is also relevant as you may have made a foreign exchange gain or loss on that amount received).
Here’s the practical advice. Start a spreadsheet. Record the income, the currency, the date, and the exchange rate you used. Do it as you go, not 10 months later when you’re trying to reconstruct a year’s worth of foreign transactions the night before your return is due. When the ATO’s data-matched information shows a different AUD figure to what you declared, the exchange rate is the first thing they look at. Having a clear record of how you arrived at your numbers is worth its weight in gold.
Double Tax Agreements: Your Protection Against Being Taxed Twice
Australia has double tax agreements with over 45 countries. Their most important function for income reporting is preventing double taxation, so the same dollar of income doesn’t get fully taxed in two countries.
If you’re an Australian tax resident earning income in a DTA country, you may be entitled to a foreign income tax offset (FITO) for the foreign tax you paid. This is a credit against your Australian tax liability, not a deduction from your income. The distinction matters. A credit reduces your tax bill dollar for dollar, up to a cap. A deduction only reduces the income the tax is calculated on.
The offset is capped at the lesser of the foreign tax you actually paid and the Australian tax that would have been payable on the same income. In high-tax countries like the Sweden or Germany, the credit often wipes out any remaining Australian liability. In lower-tax countries, or countries with no income tax (hello, Dubai), you’ll likely still owe the difference to the ATO.
One thing to be aware of – DTAs also allocate taxing rights over dividends, royalties, business profits, and government pensions, and these rules vary between agreements. The Australia-UK, Australia-US, and Australia-Singapore DTAs all work differently.
Don’t assume what applied in one country will apply in another. Check the specific agreement.
Do You Need to Lodge? Declaring Overseas Income in Australia
As a tax resident: You must lodge if your assessable worldwide income exceeds the tax-free threshold ($18,200 for 2025-26, as at the date of publication), or if you have a HELP or HECS debt, or if you have received a notice to lodge, or if you had tax withheld and want a refund.
Note that the threshold applies to total worldwide income. Even if every dollar of income is foreign-sourced and fully offset by the foreign income tax offset, you may still be required to lodge.
As a non-resident: There is no tax-free threshold. All Australian-source income is taxable from the first dollar. You must lodge if you have net rental income, capital gains on taxable Australian property, Australian business income, or any Australian income not fully covered by withholding tax.
If your only Australian income as a non-resident is interest or dividends on which the correct withholding has been applied, you may not be required to lodge – though you can choose to if you have deductions to claim.

Common Mistakes That Attract ATO Attention
We see the same errors every year. Here are the ones that generate the biggest headaches and the biggest bills.
Assuming you’re a non-resident because you live overseas. Residency is a legal determination, not necessarily a description of where you sleep. The ATO regularly challenges self-assessed non-residency, particularly in the first year or two after departure.
Believing foreign employment income is automatically exempt. The section 23AG issue is the cockroach of expatriate tax advice. It will not die. The exemption was removed for private-sector workers in 2009. If someone is still quoting it to you, find a new adviser.
Missing foreign bank interest. Even small foreign balances generate reportable interest. And the ATO now receives data on those accounts directly from overseas financial institutions through international exchange agreements. They know. You should too.
Using the wrong exchange rate. If your declared AUD figure doesn’t match the ATO’s data-matched information, it triggers a review. The discrepancy is usually an exchange rate issue, and sorting it out after the fact is never fun.
Not claiming the foreign income tax offset. If you paid foreign tax on income that’s also assessable in Australia, you’re entitled to the offset. Many expats leave this money on the table because they don’t know the credit exists or they haven’t kept records of the foreign tax paid. That’s money you’ve already paid to another government. Claim it back.
Lodging in the wrong residency category. A non-resident filing as a resident and claiming a tax-free threshold they can’t use. A resident filing as a non-resident and leaving worldwide income off the return. Both create problems that compound year after year until someone notices.
The ATO Already Knows More Than You Think
Australia has been participating in the OECD’s Common Reporting Standard since 2017. Under this framework, financial institutions in over 120 countries automatically report account information to their local tax authority, which then passes it to the ATO.
That information includes account balances, interest, dividends, and gross proceeds from financial transactions. The ATO receives it annually and matches it against lodged returns.
Australia also has a separate agreement with the United States under the Foreign Account Tax Compliance Act (FATCA), which operates alongside the CRS.
The practical effect? The ATO’s visibility over your foreign financial life has expanded dramatically. If you’ve been earning foreign income that hasn’t appeared in your Australian returns, the discrepancy has probably already been flagged. A letter may follow. An audit may follow the letter.
If you’re in that position, voluntary disclosure before the ATO contacts you is always the smarter move. The penalty reductions for coming forward unprompted are significantly more generous than what’s available once an audit begins.
To learn more about what the ATO already knows about you take a look at our guide: ATO Data Matching 2026: How They Track Your Overseas Income
What Happens If You Don’t Report?
Failure to lodge: The ATO charges a penalty for each 28-day period a return is overdue, up to a maximum of five penalty units for individuals. It adds up. Penalty unit amounts are updated periodically – current figures are located at ato.gov.au.
Tax shortfall penalty: If you lodge but under-report, a penalty applies to the tax shortfall (the gap between what you declared and what you owed). The rates are:
- 25% for negligence,
- 50% for recklessness, and
- 75% for intentional disregard.
Voluntary disclosure before the ATO contacts you reduces these to 20%, 40%, and 60% respectively. These are not small penalties on significant underpayments.
General Interest Charge (GIC): Interest accrues on unpaid tax at the ATO’s General Interest Charge rate, which is updated quarterly. On multi-year underpayments, the GIC compounds to the point where it can rival the original tax liability. We’ve seen cases where the interest alone exceeded the tax that was owed. That’s not a good conversation to have with your husband or wife, or accountant for that matter .Current rates are at ato.gov.au.
Get the Reporting Right
The underlying framework is not difficult to state. Residents declare worldwide income, non-residents declare Australian-source income only. But applying that to real circumstances, a mid-year residency change, income from several countries, a DTA with nuanced provisions, capital gains across multiple jurisdictions, is where it gets complicated quickly.
Getting it wrong costs money in both directions. Overpaying because you haven’t claimed the foreign income tax offset. Underpaying and facing penalties and interest that accumulate over years. Neither is a good outcome.
