Hello I am emigrating to the UK from the EU. I will have a job in UK and receive normal employment income and pay tax, etc However I also receive Director's fees from my duties as a Director of a Singapore based company. (duties conducted in Singapore 3 times a year) Under the UK - Singapore Tax treaty it appears that the directors fees are taxable in Singapore. Are these fees ALSO taxable in the UK or are they exempt entirely? (it appears they are?)
