Hello, I'm Keith and happy to help you with your problem. Perhaps you could expand your question a little, please. Who is your employer and where is your employer located? Furthermore, is your work all done overseas or are some duties performed in the UK and finally is this employment within the European Union (EU)? As a general rule though to avoid tax altogether when working abroad outside the EU make sure you never spend more than 90 days in the UK in each tax year.
