CGT on Shares FX Rates

My shares are listed in USD, can I use my brokers closed position report quoted in GBP as the basis of the purchase/sale proceeds or do I need to convert everything myself using the HMRC FX rates, thanks

Hi
Please have a look at the guidance at CG78310 (Foreign currency: assets acquired or sold for currency) regarding how to convert to GBP sterling.  Under the terms of Self Assessment, we do not provide an official exchange rate and the onus is on the individual to use a just and reasonable exchange rate for each acquisition and disposal.  For your convenience, there are exchange rates at Exchange rates from HMRC in CSV and XML format for older rates at Exchange Rates. You are free to use any of the supplied rates or one of your own choosing.
