Thanks for your question
Is this through the actual investing on shares and selling at a later date and making a gain or specifically forex trading.
If the former then the first £11,100 would be tax free under the capital gain rules, then the next £32000 at 18% and then the remaining gain at 28%
If forex trading then no tax liability at all as deemed to be gambling (forecasting) unless you were making this money by other peoples money in which it would then be classed as a self employment trade - and then the first £11,000 would be tax free, then the next £32000 at 20% and the remaining amount at 40%
Let me know if I can assist further
Thanks for your response
Yes you are right but I assumed (wrongly) you were talking about a gain already realised - is this not the case?
That not being the case - that you are referring to a gain post 6th April then your capital gain position is first £11,100 tax free then any unused basic rate and will allow that element of gain at 10% and any remaining gain just at 20%
