Individual (UK resi + dom) has made a gain on sale of shares in a company which I think was registered in Luxembourg. Purchase and sale were both in Euros and were 4 tax years apart. I would ordinarily calculate the GBP purchase and GBP sale using xe.com on the relevant dates, which is in line what what I can see online & within HMRC's CGM (eg CG78310).
The client has said that he thinks he can use any spot rate at any point in the tax year of disposal (pre- or post- disposal). Is this right? Can anyone point me in the direction of the legislation?
Thanks
