FX gains - personal taxation impact

In a personal capacity I have $40k USD cash, which I have moved from a US bank account into a brokerage account and converted via a single one off FX trade to sterling. There has been an FX gain of £1,500 whilst in the trading account. I am not a forex trader or day trader. 1) Is the FX gain taxable by HMRC? 2) If it is taxable does it need reporting as income or capital gain on the self assessment - and which box? 3) Are there any thresholds / allowances that I should be aware of in relation to FX gains, or volume of FX trades - as an individual / person? Thanks Adam

Hi
This would be liable to capital gains.
However, you have an annual exempt amount of £6000 for tax year 23/24 so no tax would be due on this amount.
