If you’ve retired to Australia with an overseas pension, worked overseas during the financial year, or earned income from foreign investments, you may need to declare that income in your Australian tax return.
For Australian residents for tax purposes, the Australian Taxation Office (ATO) generally requires you to report worldwide income. This means income earned both in Australia and overseas may need to be included in your tax return, even if tax has already been paid in another country.
Understanding the rules around foreign income, foreign pensions, and foreign tax offsets can help you avoid costly mistakes and ensure you meet your Australian tax obligations.
What Is Foreign Income?
Foreign income includes money earned or received from sources outside Australia, including:
- Overseas pensions and annuities
- Foreign employment income
- Income from overseas investments
- Rental income from overseas property
- Payments from overseas clients or digital platforms, including freelance or content creation income
If you’re an Australian resident for tax purposes, this income will generally need to be declared in your Australian tax return.
Foreign Pensions and Annuities
Most foreign pensions and annuities are taxable in Australia, even if tax has already been withheld overseas. However, the tax treatment depends on the type of pension and whether Australia has a double tax agreement (tax treaty) with the country paying the pension.
In some circumstances, you may be able to reduce the taxable amount.
Undeducted Purchase Price (UPP)
Some foreign pensions include an Undeducted Purchase Price (UPP).
Broadly, the UPP represents personal contributions you made towards your pension or annuity, allowing part of each payment to be treated as a return of your own capital rather than taxable income.
UK State Pension Rules
Specific rules apply to certain overseas pensions. For example, if you receive a UK State Pension, you may be entitled to claim a UPP deduction.
For a Category A Pension or Category B Widow’s Pension, the ATO allows the deductible amount to be calculated as 8% of the UK State Pension received, after converting the amount into Australian dollars.
Can You Claim a Foreign Income Tax Offset?
If you’ve paid tax overseas on income that is also taxable in Australia, you may be eligible for a Foreign Income Tax Offset (FITO).
A foreign income tax offset helps reduce the risk of paying tax twice on the same income.
Remember that foreign income, allowable deductions and foreign tax paid must generally be converted into Australian dollars before completing your Australian tax return.
Foreign Employment Income
If you’ve worked overseas during the financial year, your foreign employment income may still need to be declared in Australia.
Foreign employment income can also include payments received from overseas businesses, online platforms or international clients, depending on the nature of the work.
While some foreign employment income may be exempt from Australian tax, these exemptions are limited and depend on factors such as:
- The type of work performed
- The length of overseas service
- Your employer
- The country where the work was undertaken
- Whether a tax treaty applies
Because these rules are complex, it’s important to obtain professional advice before assuming your overseas income is tax-free.
Why It's Important to Get Foreign Income Right
Incorrectly reporting foreign income can result in significant penalties.
If your tax return contains a false or misleading statement that results in a tax shortfall, the ATO may apply penalties of:
- 25% for failing to take reasonable care
- 50% for recklessness
- 75% for intentional disregard of the tax law
Interest charges may also apply.
If you discover you’ve omitted foreign income or made an error in a previous tax return, it’s generally better to correct it as soon as possible.
Making a voluntary disclosure may reduce any penalties that apply.
