The Australian Taxation Office (ATO) has published the foreign exchange rates for the financial year ending 30 June 2026, including annual average exchange rates and the nearest actual exchange rates as of 30 June 2026 for 18 currencies.
All foreign income, deductions, and foreign tax paid must be converted to AUD before being included in the return.
There are rules about which exchange rate to use. Generally, these require amounts to be converted at the exchange rate prevailing at the time of a transaction, or at an average rate.
Earlier, the Australian Taxation Office (ATO) updated its foreign exchange rate guidance, which includes the monthly exchange rates for 1 July 2025 to 30 June 2026 and the monthly rates for June 2026.
