Foreign income and Australian tax: the complete guide for residents
Foreign income and Australian tax: the complete guide for residents
If you are an Australian resident for tax purposes, you are taxed on your worldwide income — not just what you earn in Australia. Foreign pensions, overseas rent, offshore dividends, aid work and capital gains on foreign property all interact with the Australian return in specific ways, and a foreign income tax offset usually stops you being taxed twice. This guide walks through every component, how each is reported, and where a tax adviser adds value beyond self-lodging.
Quick answer
An Australian tax resident includes the gross amount of foreign income (the income plus any foreign tax withheld) in their assessable income, then claims a foreign income tax offset (FITO) for the foreign tax paid, subject to a cap. Some foreign employment income — such as qualifying overseas aid or non-warlike peacekeeping — is exempt, but must still be disclosed because it raises the tax rate applied to the rest of your income. Temporary residents are treated very differently: most of their foreign income is not taxed in Australia at all.
The governing principle: residency decides everything
Australian residents for tax purposes are assessed on income from all sources, worldwide. Foreign residents and temporary residents are taxed on a different basis, so confirming your residency status is always the first step. For a resident, the default treatment of any foreign income follows one rule:
Add back the foreign tax to get the gross amount, subtract related deductions to the net figure, then claim the foreign tax as a FITO.
The components of foreign income and how each is taxed
Different types of foreign income sit at different labels on the tax return. The gross assessable total always goes at Item 20E, with the net amount for each category flowing to its own label.
| Type of foreign income | How it is taxed | Return label |
|---|---|---|
| Foreign employment (no PAYG summary) | Gross at 20E, net of deductions at 20T. Deductions are not claimed at D1–D5. |
20E / 20T
|
| Foreign employment (Australian employer, PAYG foreign-employment summary) | Treated as foreign service income — gross at Item 1, deductions at D1–D5, net at 20U. | 20U |
| Foreign pension or annuity | Assessable in the country of residence under most treaties. Age and whether funds are remitted are irrelevant. |
20L / 20D
|
| Foreign rental income | Gross at 20E, net at 20R. Foreign loan interest is a debt deduction at D15, not against the rent. |
20R / D15
|
| Foreign interest, dividends, royalties, business income | Gross at 20E, net at 20M. No relief for foreign imputation credits. | 20M |
| Australian franking credits from a New Zealand company | Only where the NZ company joined the Australian imputation system. NZ imputation credits are never claimable. | 20F |
| Foreign capital gains | Taxed like domestic CGT; the 50% discount applies if held 12 months or more. | Item 18 |
| Exempt foreign employment / service income | Not assessable, but disclosed because it raises the rate on your other income. | 20N |
| Foreign income tax offset | Credit for foreign tax paid (not income in its own right). | 20O |
The foreign income tax offset (FITO): avoiding double tax
Where foreign tax has been paid on income that is also assessable in Australia, a FITO reduces your Australian tax. The foreign tax must be a genuine income tax, actually paid, on income included in your Australian assessable income. There are two paths:
$1,000 or less
Claim in fullUnder the de minimis rule, if total foreign tax paid is $1,000 or less, claim it in full at 20O with no calculation required.
Above $1,000
Cap appliesEither cap the claim at $1,000 and lose the excess, or calculate the FITO cap — the Australian tax attributable to the foreign income — and claim up to that amount.
The FITO cap is the difference between the tax (including Medicare levy and surcharge) on your whole taxable income, and the tax on that income with the foreign income and related deductions removed. You claim the lesser of the foreign tax paid and the cap.
Worked example: pension taxed heavily overseas
Priya is single and an Australian resident. She receives a foreign pension of $40,000 gross, from which $14,000 of foreign tax was withheld. Her Australian salary is $70,000 with no deductions.
Tax + Medicare on $110,000 = $25,988
Tax + Medicare on $70,000 (Aus only) = $13,188
FITO cap = 25,988 − 13,188 = $12,800
Foreign tax paid $14,000 > cap $12,800
FITO claimable = $12,800 — $1,200 is lost
Because the foreign country taxed the pension at 35% — above Priya's effective Australian rate on that slice — the cap bites and $1,200 of foreign tax cannot be recovered. Had the foreign tax been $9,000, the whole amount would have been claimable.
Exempt foreign employment income: three sections, three outcomes
Some foreign employment income is exempt from Australian tax. Which section applies changes not just whether it is taxed, but whether it appears on the return at all. All three require 91 or more days of continuous foreign service.
Section 23AG — aid, relief and peacekeeping
Shown at 20NApplies where the foreign service is directly attributable to: delivery of Australian aid (ODA) by a non-government employer; operation of a developing-country or disaster relief fund; a charitable or religious institution based offshore; or deployment as a disciplined force member (defence, police, peacekeeping) in a non-warlike operation. Exempt, but disclosed at 20N so the rate on your other income is calculated correctly.
Section 23AD — warlike deployment
Not on the returnCovers ADF members on eligible duty in a warlike operation. The payment summary lists the exemption and the days; the income is not included in the return at all.
Section 23AF — approved overseas projects
Needs project numberCovers work on a national-interest project approved by Austrade. Subject to the same 91-day rule, but you must obtain the project approval number from your employer before lodging.
The 91-day continuity test: which breaks are safe?
The exemption needs a continuous period of 91 days or more. Any absence breaks continuity unless it is no more than one-sixth of the service to that point, or the absence itself counts as foreign service.
Counts as service
- Recreation leave earned on the job
- Days off in lieu, weekends, public holidays
- Approved sick leave
- Short work-related trips home
Breaks continuity
- Long service leave
- Leave without pay
- Maternity or extended leave
Converting foreign income into Australian dollars
All foreign income, deductions and foreign tax must be translated to Australian dollars, using the spot rate at the relevant time or a reasonable average rate.
| Item | Exchange rate used |
|---|---|
| Ordinary income (salary, business, PSI) | Earlier of the time it is derived or received |
| Statutory income other than capital gains | Earlier of receipt or when it must be included as assessable |
| Capital gain | Proceeds and each cost-base element at the time of receipt or payment |
| Trading stock valued at cost | Rate when the item became on hand |
| Trading stock valued at market / replacement cost | Rate at the end of the income year |
Temporary residents: a different regime entirely
Temporary residents — broadly, holders of a temporary visa who are not residents under the Social Security Act, with no Australian-resident spouse — get concessions permanent residents do not.
- Most foreign investment income is non-assessable and never declared
- Capital gains apply only to taxable Australian property
- Only foreign employment income earned while a temporary resident is assessable
Foreign losses and the gross-up in practice
Since 1 July 2008 foreign losses are no longer quarantined — a foreign rental loss now offsets Australian salary dollar-for-dollar. And the gross-up rule is easy to get wrong:
Worked example: gross-up on foreign wages
Marco receives $32,350 in foreign employment income after $10,500 of foreign tax was withheld. His related work expenses were $650.
Item 20T (net) = 42,850 − 650 = $42,200
The $10,500 foreign tax then drives the FITO at 20O.
Entering the $32,350 net figure would understate both his assessable income and his FITO base. Australia taxes the gross and hands back a credit — never both a reduced income and the offset.
Exempt income still shapes your rate
Exempt foreign employment income at 20N is not taxed, but it lifts the average rate applied to your other income.
Worked example: the notional rate
Sofia earned $22,000 in exempt aid income and $45,000 in Australian salary, with no deductions.
Tax + Medicare on $67,000 = $12,228
Notional average rate = 12,228 ÷ 67,000 = 18.251%
Applied to actual income $45,000 → about $8,213
(vs about $5,188 if the exempt income were ignored)
The aid money stays tax-free, but Sofia's salary is taxed as though she earns $67,000, not $45,000. Leaving the $22,000 off the return does not save tax — it simply understates the rate and is an accuracy error.
Tax-planning checklist
- Confirm residency status first — resident, foreign resident, or temporary resident
- Gross up every foreign amount by the foreign tax withheld before entering 20E
- Where foreign tax exceeds $1,000, calculate the FITO cap rather than defaulting to the $1,000 shortcut
- Remember the 50% CGT discount halves the FITO on foreign gains
- Disclose exempt foreign employment income at 20N even though it is not taxed
- Confirm the employer type and deployment nature before applying a 23AG, 23AD or 23AF exemption
- Apportion foreign income that straddles two Australian financial years
- Review disposals and status changes before a temporary resident loses their concessions
Where an adviser adds value
Explaining how FITO, exemptions or the temporary-resident rules work is general information. Choosing the timing of a disposal, electing on a foreign super transfer, or restructuring before a status change is personal tax advice — and anything touching a foreign super fund or financial product may need a licensed financial adviser. Based on your residency status and holding period, a practitioner can identify recoverable foreign tax and timing opportunities that self-lodging tools routinely miss.
Frequently asked questions
Do I pay Australian tax on my overseas income?
If you are an Australian resident for tax purposes, yes — you are taxed on worldwide income. You include the gross foreign amount and usually claim a foreign income tax offset for tax already paid overseas, so you are not taxed twice. Temporary residents are largely exempt on foreign income.
What is the foreign income tax offset (FITO)?
It is a credit for foreign income tax you have paid on income that is also assessable in Australia. If the foreign tax is $1,000 or less you claim it in full; above that, you claim up to a cap equal to the Australian tax attributable to the foreign income.
Do I enter the gross or net amount of foreign income?
Always the gross amount — the income plus any foreign tax withheld — at Item 20E. The net-of-tax cash you actually received never appears on the return; the foreign tax is claimed separately as a FITO at 20O.
Is my foreign aid work tax-free in Australia?
Overseas aid can be exempt under section 23AG if you complete 91 or more days of continuous service for a non-government employer delivering aid, a relief fund, an offshore charity, or a non-warlike disciplined force. A government-agency aid worker doing the same job is not exempt.
Does the 50% CGT discount affect my foreign tax offset?
Yes. If the 50% discount means only half of a foreign capital gain is assessable in Australia, only half of the foreign tax paid on that gain counts toward your FITO. The same halving applies where a gain is reduced by a capital loss or small business concessions.
What exchange rate do I use to convert foreign income?
Ordinary income uses the earlier of when it was derived or received. Capital gains use the spot rate at the time proceeds and cost-base elements are received or paid. A reasonable average rate can be used where it approximates the spot rate, but not for one-off transactions like an asset sale.
Are temporary residents taxed on foreign income?
Mostly no. Temporary residents' foreign investment income is non-assessable and not declared, and capital gains apply only to taxable Australian property. Only foreign employment income earned while a temporary resident is assessable.
Where does exempt foreign employment income go on the tax return?
At Item 20N. It is not taxed, but it must be disclosed because it is used to raise the average rate of tax applied to your other assessable income. Leaving it off understates that rate.
