I need some advice on managing transactions in a foreign brokerage account with USD as the base currency, particularly concerning the remittance basis of taxation. 1) When buying and selling futures contracts, do I need to record these transactions in GBP at each transaction level, or is it sufficient to do so only when remitting to the UK? 2) If I need to track each transaction in GBP, there could be a discrepancy in the exchange rate when I withdraw USD from the brokerage account and when it’s converted to GBP in the UK. For instance, I might withdraw an amount equivalent to £10,000, but by the time it’s converted to GBP in the UK, it might be £9,500. -Which amount should I consider as withdrawn from the brokerage account? -Which amount should I record as remitted to the UK? 3)If I use the arising basis in some years and the remittance basis in others, does this affect how I should track transactions?
