I'm doing my SA calculations for the 04-05 tax year.
I sold some US stock which I'd held for a few years. The stock has lost about 10% in value, but the drop in the dollar has had a much more severe effect. The exchange rates were about 0.7 UKP/dollar when I bought the stock and had dropped to about 0.55 UKP/dollar when I sold it.
Am I correct that the CGT owing should be calculated by: (money from sale * exchange rate on date of sale) - (purchase cost * exchange rate on date of purchase)?
Or should I just take the difference in US $ between the proceeds and cost and multiply that by the US/UK exchange rate on the date of the sale?
If I do the first method then I end up with a CGT loss of over 40K UKP!
Assuming this is the correct method of making this calculation, are the Revenue likely to accept this without question? Since my account was with a US broker, I don't have any copies of the contract notes. Worse, all my statements were sent electronically, and I rather doubt the Revenue would accept anything I simply printed out myself. I suppose I could get copies of my statements if needed, but since I have closed the account (and no longer have any funds in the US to pay them for sending me duplicate statements), this seems likely to be a painful process.
Any thoughts would be appreciated.
