Whether you're an Australian working overseas, receiving foreign investment income, or a newcomer to Australia with overseas assets, understanding how foreign income is taxed is crucial. This guide covers residency rules, foreign tax credits, reporting requirements, and strategies to avoid double taxation.
The Key Principle
Your tax obligations depend on your residency status:
- Australian residents: Taxed on worldwide income
- Foreign residents: Taxed only on Australian-sourced income
- Temporary residents: Special rules apply (middle ground)
Determining Your Tax Residency
Tax residency is different from visa status or citizenship. The ATO uses several tests to determine if you're an Australian resident for tax purposes:
The Four Residency Tests
1. Resides Test (Primary)
You're a resident if Australia is your ordinary residence. Factors considered:
- Physical presence in Australia
- Intention and purpose of presence
- Family ties and relationships
- Business and employment ties
- Maintenance of assets in Australia
- Social and living arrangements
2. Domicile Test
If your domicile (permanent home) is in Australia, you're a resident unless:
- Your permanent place of abode is overseas, AND
- You don't intend to return to live in Australia
3. 183-Day Test
You're a resident if you're present in Australia for more than half the income year (183 days), unless:
- Your usual place of abode is overseas, AND
- You don't intend to take up residence in Australia
4. Superannuation Test
Certain Australian Government employees working overseas are treated as residents if they're members of specific super schemes (CSS, PSS).
Important Note
Residency is determined based on your individual circumstances. You may be a resident of Australia for tax purposes even if you're overseas, and vice versa. Each case is assessed on its facts.

Types of Foreign Income
If you're an Australian resident, you must declare all foreign income, including:
Common Foreign Income Types
- Employment income: Salary and wages from overseas employers
- Pension income: Foreign government or private pensions
- Rental income: From overseas property
- Interest income: From foreign bank accounts
- Dividend income: From foreign companies
- Capital gains: From selling overseas assets
- Business income: From overseas business activities
- Trust distributions: From foreign trusts
Foreign Income Tax Offset (FITO)
To prevent double taxation, you may be entitled to a Foreign Income Tax Offset for foreign tax paid on income that's also taxable in Australia.
FITO Calculation
The offset is limited to the lesser of:
- The foreign tax actually paid, OR
- The Australian tax payable on that foreign income
Simple rule: If foreign tax is $1,000 or less, you can claim the full amount without complex calculations.
FITO Example
Foreign Dividend Income
Sarah received $10,000 in US dividends with $1,500 US withholding tax:
| Gross foreign dividend | $10,000 |
| Foreign tax withheld (15%) | $1,500 |
| Net received | $8,500 |
| Taxable in Australia (gross) | $10,000 |
| Australian tax @ 32.5% | $3,250 |
| Less FITO | -$1,500 |
| Net Australian tax | $1,750 |
Double Taxation Agreements (DTAs)
Australia has tax treaties with over 45 countries to prevent double taxation and allocate taxing rights. Key features include:
