Changing domicile is apparently very difficult but non residence is the term for tax purposes. I pay no UK tax on anything earned outside of uk (even though working for a uk company) and declare anything (which is nearly nothing) earned inside. But it's not as cut and dried as you might think. i spoke an office and phoned as well and the gist of it was " if you're non resident and earning money outside the uk we don't care". Determining nonresident is the bit which isn't cut and dried I think, property may be a problem as they might see you as just going on a "big holiday for a few years", I sold my house. Can't remember the no of days (travel days count now as well) allowed inside UK and how many years you need to be away for but that will all be on a inland revenue somewhere. How long are you panning to go for? I can't afford to go back now as I'd get hammered for tax, oh well, I'll stay in the sun then
