Who This Guide Is For
This guide is for Australian tax residents who earn income from overseas sources — whether you are a migrant maintaining assets in your home country, an expat who moved to Australia with foreign investments, a working holiday maker with overseas bank accounts, or an Australian citizen receiving a foreign pension. If you receive any of the following, the ATO expects you to report it: foreign employment income, rental income from overseas property, dividends from foreign shares, interest from foreign bank accounts, foreign pension payments, capital gains on overseas assets, or trust distributions from foreign entities.
Australia taxes its residents on worldwide income — this is fundamentally different from countries like Singapore or Hong Kong that operate territorial tax systems. Once you are an Australian resident for tax purposes, all income you earn anywhere in the world becomes taxable in Australia, regardless of whether you bring the money into the country.
This guide covers the FY2025–26 rules, including the foreign income tax offset, double tax agreements, and practical steps to stay compliant.
How Australia Taxes Foreign Income
What Is "Worldwide Income" Taxation?
Australia's tax system is residence-based. Under ATO guidelines, an Australian tax resident must declare income from all sources — Australian and foreign. This includes:
- Salary or wages from an overseas employer
- Business income from a foreign company or sole trader activity
- Rental income from property located overseas
- Dividends from foreign companies
- Interest on foreign bank accounts
- Capital gains from selling overseas assets (shares, property, businesses)
- Foreign pension and annuity payments
- Royalties from overseas intellectual property
- Trust distributions from foreign trusts
According to the ATO, if you are an Australian resident for tax purposes, you must declare all foreign income in your Australian tax return — even if tax was already withheld in the source country, and even if you never transferred the money to Australia.
Foreign Employment Income
If you work remotely for an overseas employer while living in Australia, the salary is Australian-sourced employment income. You must declare the gross amount on your tax return, converted to Australian dollars using the ATO's published exchange rates for the relevant period.
You can claim a foreign income tax offset if your employer withheld tax in the source country (see section below).
The Foreign Income Tax Offset (FITO)
How FITO Works
Australia has a foreign income tax offset (FITO) system to prevent double taxation. If you paid foreign tax on income that is also taxable in Australia, you can claim a non-refundable offset up to the lesser of:
Calculation example:
Suppose you earned AUD $15,000 in rental income from a property in the UK in FY2025–26. The UK withheld AUD $3,000 in tax. Your Australian marginal tax rate is 30%, so Australian tax on that income would be $15,000 × 30% = $4,500. You can claim the full $3,000 as a FITO because $3,000 < $4,500. Result: you pay an additional $1,500 to the ATO and receive no refund for the UK tax — the offset simply reduces your Australian liability.
If the UK had withheld $6,000 instead (exceeding Australian tax of $4,500), your FITO is capped at $4,500, and the excess $1,500 is not refundable and cannot be carried forward.
What FITO Does NOT Cover
| Expense | Deductible as FITO? |
|---|---|
| Foreign income tax paid on the same income | ✅ Yes |
| Foreign capital gains tax on overseas property | ✅ Yes |
| Foreign VAT / GST on purchases | ❌ No |
| Foreign social security contributions | ❌ No |
| Municipal / council rates on overseas property | ❌ No (claim as rental expense instead) |
Double Tax Agreements (DTAs)
Australia has tax treaties with over 45 countries including the UK, USA, China, India, New Zealand, Singapore, Canada, Germany, and Japan. These treaties allocate taxing rights between Australia and the treaty partner — they do not exempt you from Australian tax on foreign income, but they influence which country has the primary right to tax specific income types.
Key DTA Rules by Income Type
| Income Type | Typical DTA Treatment |
|---|---|
| Employment income | Taxed where the work is physically performed |
| Rental income | Taxed where the property is located |
| Dividends | Source country may impose withholding tax (usually 10–15%); Australia taxes the balance |
| Interest | Source country withholding tax typically capped at 10% |
| Government pensions | Usually taxed only in the paying country |
| Private pensions | Usually taxed only in the recipient's country of residence |
Example — US/Australia DTA: An Australian resident receiving US Social Security payments only pays tax in Australia (not the US), per Article 17 of the treaty. But US 401(k) distributions may be taxable in both countries, with FITO available in Australia.
Converting Foreign Income to Australian Dollars
The ATO requires foreign income to be reported in Australian dollars. You have two options:
Be consistent: if you use the ATO annual average, use it for all foreign income of the same type.
Foreign Rental Property
If you own rental property overseas, you must report:
- Gross rental income (converted to AUD)
- Claim the same deductions an Australian property allows: mortgage interest, council rates, repairs, property management fees, insurance, and depreciation (if the foreign country's rules permit it)
The net rental income (or loss) flows into your Australian assessable income. A foreign rental loss can offset other Australian income, reducing your overall tax — but be aware of any foreign loss restrictions in the source country.
Foreign Shares and Capital Gains
Selling foreign shares triggers an Australian CGT event if you are a resident. The capital gain is calculated as:
Sale proceeds (AUD) – Cost base (AUD) = Capital gain
The cost base is the purchase price converted at the exchange rate on the date of purchase — not the date of sale. This means currency movements between purchase and sale can create or reduce a capital gain independently of the share price movement.
Example: You bought US shares for USD $10,000 when AUD/USD was 0.70 (cost base = AUD $14,286). You sold them for USD $12,000 when AUD/USD was 0.65 (proceeds = AUD $18,462). Capital gain = $18,462 – $14,286 = $4,176. If you held the shares for more than 12 months, you may be eligible for the 50% CGT discount, reducing the taxable gain to $2,088.
Common Mistakes Australians Make with Foreign Income
| Mistake | Why It's Wrong | What to Do Instead |
|---|---|---|
| Not declaring foreign income because it "never entered Australia" | Australian tax is assessed on worldwide income, not on remittance | Report all foreign income regardless of whether you transfer it to Australia |
| Claiming FITO for foreign VAT/GST | FITO only applies to income tax (or foreign CGT), not consumption taxes | Only claim FITO for foreign taxes that are substantially similar to Australian income tax |
| Using the wrong exchange rate | Inflated or inconsistent rates can trigger ATO data matching | Use ATO published rates or documented commercial rates consistently |
| Assuming all DTAs exempt foreign income | DTAs allocate taxing rights; you still report the income in Australia and claim FITO | Read the specific DTA article for your income type before assuming an exemption |
| Not declaring foreign superannuation / pension | Foreign pensions are taxable in Australia for residents | Declare all foreign pension income; check the relevant DTA for special treatment |
Records to Keep
- Foreign employment contracts and payslips
- Foreign bank statements showing interest and dividend income
- Foreign tax assessments or withholding certificates (essential for claiming FITO)
- Property purchase and sale contracts (for CGT cost base)
- Rental property income statements and expense receipts
- Exchange rate sources used for AUD conversion
- Trust distribution statements from foreign trusts
The ATO requires you to keep records for five years after you lodge your tax return.
Quick Checklist
- Determine your Australian tax residency status for FY2025–26
- List all foreign income sources (employment, rental, dividends, interest, pension, capital gains, trusts)
- Obtain foreign tax payment evidence for each income type
- Convert each income amount to AUD using the ATO rate or documented commercial rate
- Calculate your foreign income tax offset for each income type
- Check the relevant DTA for any special provisions
- Keep all foreign income records for at least 5 years
- Consider whether a registered tax agent can help with complex foreign income situations
