The Australian Taxation Office (ATO) has updated its foreign exchange rate guidance, which includes the monthly exchange rates for 1 July 2025 to 30 June 2026 and monthly rates for April and May 2026.
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.
