HMRC Exchange Rates

These are HMRC official monthly average exchange rates for September 2018, published by HM Revenue & Customs for use in UK tax calculations. Each rate represents the average number of foreign currency units per £1 during the month. To convert a foreign amount to sterling, divide by the rate shown.

These rates are accepted by HMRC for capital gains tax calculations on the disposal of foreign assets — including overseas property, foreign shares, and other non-sterling investments. Calculate your CGT using these rates →
