Foreign Currency Translation Rules
The tax rules require tax returns to be prepared in Australian dollars.
For most transactions, taxpayers have a choice of translation method:
- prevailing exchange rate on the date of transaction; or
- average exchange rate for the financial year (or lesser period).
A third method applies the rates conforming to accounting standards for an audited financial report for an entity.
The use of average rates for a period must be a “reasonable approximation” of the prevailing transaction spot rates.
‘Reasonable approximation’ currency translation examples
The Tax Office has provided examples of what is considered “reasonable”:
- An Australian resident receiving periodical payments of a pension from Italy can translate the amounts using an average annual exchange rate;
- A taxpayer receiving a pension from the UK which is periodically credited to her bank account in Australian dollars, can choose to use the total in Australian dollars as the translated amount, without the need for any other conversion.
- A business which buys trading stock from Germany and settles the payments in Euros approximately 6 times a month, can use an appropriate average rate of exchange for the cost of trading stock
- An Australian consulting engineer accounting on an accruals basis receiving monthly income from US clients can translate the USD amounts using a yearly or monthly average
- The Australian consulting engineer in the previous example buys an office building in New York for $US 3 million, cannot translate using a yearly average exchange rate because it would not be a “reasonable approximation”.
- A taxpayer has a rental property in the UK. The rent received and expenses are handled in UK bank account. He can use an average rate of exchange for translation.
- The taxpayer in the previous example sells the rental property. An average exchange rate for the transaction would not be appropriate.
Special Translation Rules
s 960-50(6) has some “special translation” rules determining the exchange rate for specific amounts.
They include [simplified summary]:
- a forex event 4 cessation of an obligation is converted at the prevailing exchange rate at tax recognition time [mentioned for reference purposes only; forex events (gains and losses) are not within the scope of this article. See further Foreign exchange gains and losses]

- trading stock valued at cost is translated at the date it became on hand
- trading stock at its market selling value or its replacement value is translated at the year-end exchange rate
- capital gains events are translated at the time of the event
- ordinary income is translated at the earlier of the time of receipt or when it is derived
- statutory income is translated at the earlier of the time of receipt or when the requirement first arose to include it in your assessable income.
- deduction amounts (not not being Div 40 deductions) are translated at the earlier of the time of payment or when it became deductible [Div 40 relates to depreciation]
- film production expenditure under Div 376 is translated according to an average rate based on the period of production
