Have Tax Questions? Ask a Tax Expert for Answers ASAP
When you say working abroad, do you mean relocating to Japan and Pakistan?
You might find yourself in difficulties and being resident in noless than three countries and having to rely on Double Taxation Treaties for protection.
That does not necessarily apply to other countries or even the UK. You can find yourself resident in the UK for a mere 14 days and still liable to UK taxation.
Well no, but just bear in mind that you cannot just swan around the world not paying tax anywhere.
