What are HMRC monthly average rates?
HMRC publishes official monthly average exchange rates for use in UK tax calculations. Each rate represents the average number of foreign currency units per £1 during that month. To convert a foreign currency amount to sterling, divide by the rate shown.
Using these rates for capital gains tax
When a UK resident disposes of a foreign asset, HMRC requires the gain to be calculated in sterling using the exchange rate at acquisition and disposal. TealFX applies the correct rate automatically for both dates. Try the calculator →
