Average Exchange Rates

The Income Tax Act, 1962, provides specifically that certain amounts expressed in a foreign currency must be translated into rand by the application of an applicable average exchange rate.
The term “average exchange rate” is defined in section 1(1) of the Act and means, in relation to a year of assessment,   the average exchange rate determined by using the closing spot rates at the end of daily or monthly intervals during a year of assessment. This rate must be applied consistently within that year of assessment.
The South African Reserve Bank (SARB) determines weighted average exchange rates, based on the foreign exchange transactions of commercial banks. SARS publishes these rates on a quarterly basis, which may be used by stakeholders (taxpayers) in the determination of the average exchange rate when required in the Act.
The next update can be expected in June 2024.
The use of these average exchange rates is not compulsory. Stakeholders using average exchange rates which differ from those published by SARS must, however, keep record of all calculations for audit purposes.
