Australia’s Foreign Income Tax Offset (FITO) lets you credit foreign tax you’ve already paid on overseas income against your Australian tax bill. If the foreign tax converts to A$1,000 or less for the year, you claim the full amount with no extra calculation. Above A$1,000, a statutory limit caps how much of the foreign tax you can actually use, and anything over that limit is permanently lost. FITO cannot be carried forward, transferred, or refunded as cash.
Who Can Claim It
Eligibility sits in Division 770 of the Income Tax Assessment Act 1997.1Australian Taxation Office. 20. Foreign Income Tax Offset Two things have to line up. First, you need to be an Australian tax resident during the income year in which the foreign-taxed amount is included in your assessable income. Tax residency is not the same as citizenship or visa status; it turns on where you ordinarily reside, your family and economic ties, and time spent in Australia.
Second, you must have actually paid the foreign tax. Under Section 770-10, the offset counts only if the tax was paid on an amount included in your assessable income for that year.2Australian Taxation Office. CR 2014/19 – Income Tax: Foreign Income Tax Offset: Brazilian Tax Paid on Employment Income by Vale S.A. Employees Tax withheld at source by a foreign employer or bank is treated as paid. If the foreign government later refunds or waives it, the entitlement disappears.
One boundary worth stating up front: if you hold a temporary visa and qualify as a temporary resident for tax purposes, most foreign income sits outside your Australian return entirely. Temporary residents declare Australian-source income, capital gains on taxable Australian property, and certain overseas employment income only.3Australian Taxation Office. Foreign and Temporary Residents Where foreign dividends, interest, and rental income are not assessable, there’s nothing to offset in the first place.
Which Income and Which Foreign Taxes Count
The range of qualifying foreign income is wide: overseas salary, dividends from foreign companies, interest on foreign bank accounts, rental income from overseas property, and capital gains on foreign assets all count, provided they are included in your Australian assessable income for the year.
The foreign tax itself has to meet a definition. To count towards FITO, it must be imposed under a foreign law and fall into one of these categories:4Australian Taxation Office. When a FITO Applies
- A tax on income, such as standard income taxes on wages, business profits, or investment returns.
- A tax on profits or gains, including capital gains taxes.
- Any other tax covered by a treaty under the International Tax Agreements Act 1953.
Foreign penalties, late-payment interest, municipal rates, and turnover-based taxes that aren’t levied on net income or profits don’t qualify. They are administrative charges, not taxes on income. If the ATO concludes what you claimed was an ineligible charge, the offset is disallowed.
Treaty Rate Caps
Where Australia has a tax treaty with the source country, only the treaty-limited amount of foreign tax counts. If a treaty caps withholding on interest at 10% but the foreign country actually withholds 25%, only the 10% portion feeds into your FITO. The excess 15% has to be recovered from the foreign tax authority, not claimed here.4Australian Taxation Office. When a FITO Applies
How Much You Can Actually Claim
The A$1,000 Shortcut
If your total foreign tax for the year converts to A$1,000 or less, record the amount paid and claim it. That’s the full offset. No limit calculation is required.5Australian Taxation Office. Calculate Your FITO or Offset Limit
The Limit Above A$1,000
Once foreign tax exceeds A$1,000, Section 770-75 of the Income Tax Assessment Act 1997 imposes a cap.6Australian Taxation Office. TD 2020/7 The limit is designed to keep the offset from exceeding the Australian tax attributable to your foreign income. You compare two figures:
- Your actual Australian tax liability on all income for the year.
- A hypothetical Australian tax liability calculated as if your assessable income did not include the foreign income on which foreign tax was paid, and as if you had no deductions reasonably related to that income.
The difference is your FITO limit. Your actual offset is the lower of the foreign tax paid or that limit.5Australian Taxation Office. Calculate Your FITO or Offset Limit Where the foreign country taxes at a higher rate than Australia would on the same income, the limit is what bites, and the extra foreign tax has nowhere to go.
Deductions in the Hypothetical
The hypothetical calculation strips out deductions reasonably related to the disregarded foreign income. A deduction tied exclusively to foreign income drops out. A deduction that straddles foreign and domestic income, such as head office or general administration cost, gets apportioned on a reasonable basis.5Australian Taxation Office. Calculate Your FITO or Offset Limit Gifts, personal superannuation contributions, and tax agent fees are not treated as reasonably related to foreign income, so they stay in the hypothetical unchanged.
Foreign losses reduce your FITO capacity too. All foreign income is aggregated, and related deductions are netted against it. If deductions exceed income in that basket, net foreign income shrinks and the limit shrinks with it.
Currency Conversion
Foreign income and foreign tax paid must be converted to Australian dollars before entering them on your return. Use the exchange rate prevailing at the time of the transaction or an average rate for the period. Since January 2020 the ATO has referenced Reserve Bank of Australia rates.7Australian Taxation Office. Foreign Exchange Rates For currencies the RBA doesn’t list, any reasonable externally sourced rate is acceptable. Record the specific date and rate for each conversion.
Capital Gains and the 50% Discount
Capital gains on foreign assets qualify for FITO, but the CGT discount has an effect worth flagging. If you held the asset for more than 12 months and apply the 50% CGT discount, only half the gain is included in assessable income. Because the offset works off the assessable portion, FITO is generally limited to 50% of the foreign tax paid on that gain. The other half of the foreign tax cannot be offset or carried forward.
What Happens to Excess Foreign Tax
FITO is non-refundable, so it can reduce your income tax to zero but won’t produce a cash refund on its own. Any FITO left over after zeroing income tax is automatically applied against Medicare levy, and then against Medicare levy surcharge if any is owing.8Australian Taxation Office. Claiming a Foreign Income Tax Offset
Whatever remains after that is lost. The ATO is explicit: foreign income tax paid in excess of the limit cannot be carried forward to a later year and cannot be refunded.5Australian Taxation Office. Calculate Your FITO or Offset Limit It also cannot be transferred to another taxpayer. This is why the limit calculation matters so much: if your foreign income was taxed more heavily than Australia would tax it, the shortfall in offset is permanent.
Claiming FITO on Your Return
FITO is reported in the foreign income section of your individual tax return. For claims of A$1,000 or less, you enter the amount and you’re done. For claims over A$1,000, you also lodge a Foreign Income Tax Offset Schedule setting out the limit calculation.
The calculation trips people up most often on which deductions relate to foreign income and how to apportion shared costs. That’s the area the ATO tends to adjust on review, and it’s where a registered tax agent earns their fee if you have multiple foreign income sources.
Amending an Earlier Return
If you pay foreign tax after lodging the Australian return for the year the income was assessed, you can request an amended assessment. A four-year amendment period applies, running from the date you actually paid the foreign income tax rather than from the original assessment date.9Australian Taxation Office. Guide to Foreign Income Tax Offset Rules 2025 That’s longer than the standard two-year window for individuals and exists because foreign tax bills often land well after the Australian year has closed.10Australian Taxation Office. Time Limits on Tax Return Amendments
Records and Penalties
Section 262A of the Income Tax Assessment Act 1936 requires you to keep records supporting the claim for at least five years, measured from when the records were prepared or obtained, or from the completion of the transactions they relate to, whichever is later.11Australian Taxation Office. Taxation Ruling TR 96/7 – Income Tax: Record Keeping – Section 262A – General Principles Keep foreign tax assessments, withholding certificates, dividend statements, exchange rate records, and your limit calculation worksheets.
If an audit finds errors, penalties are calibrated to behaviour:12Australian Taxation Office. Penalties for Making False or Misleading Statements
- Failure to take reasonable care: 25% of the shortfall.
- Recklessness: 50% of the shortfall.
- Intentional disregard: 75% of the shortfall.
If you can’t produce the supporting documents during an audit, the offset can be denied outright on top of any penalty. Foreign-language documents and historical exchange rates are hard to reconstruct years later, so file each document when it arrives.
