Sorry for the typo: I dont meen "Swiss Citizen" I meant to say "Swiss resident" with permit B.

You don't have to pay UK tax if you aren't resident there. What may have happened is a withholding tax. It means they keep the money on the assumption that you're supposed to pay tax, but if actually you're not you can get it back.

I haven't had any issues like that and I'm a British citizen. But I told HMRC I was leaving. It took them forever to stop sending me the tax return, but eventually I got them to give it up. I never had to pay anything though.

I'm a UK citizen and I've started working recently on a UN consultancy (so I'm paid as a consultant, not a staff member) in Geneva. I'm really confused about whether I should pay tax, and if so, whether it's here in Switzerland where I now live or in the UK where I lived and worked and paid tax until August. I may return to the UK in a year or so when my contract finishes but that's unclear just yet. Does anyone know anyone who can give me good clear advice on this? All help appreciated!
