Hi HMRC team, hope you are well! For ESPP of an US company and traded on the NYSE, I paid tax on the fair market value at the time that it was made available to me, let's say $160 was the stock prices, and my "cost" was $100. I sold a little while after that and the share price at that time was lower than the initial fair market value (let's say now it is $150). As such, I paid the income tax on the $60 profit I made, but I actually realized $50 of profit. In this case, are there any taxes I could claim back? If so, how can I do this?
