Not cut ties permanently but they've accepted I'm not a tax payer there at the moment (they look back over the last 5 years to pull you back into UK tax) and still have some cash in UK banks.In your case; have you cut ties permanently with the UK and is your tax residency in Thailand kind of recognised and accepted by the UK?
For the moment I've got a visa to stay in Thailand for 10 years and a Thailand tax ID.
Times have changed.Why do you think so? I did it without the slightest troubles a few years ago. And I lived in one of the highest tax paying countries in the world.
Many European countries are trying to keep you tied as much to them as they can so that they can continue to collect taxes. This means that if they find your story not plausible they will immediately treat it as a way to evade taxes and that makes that you are forced to proof that it is not to evade taxes but a legitimate move for whatever purpose. Any connection to your passport country then works against you. A connection in that sense is nowadays already when you have family and a bankaccount left in your passport country.
We knew the Dutch and Spanish tax authorities are displaying this behaviour. A solid third place is for France and Germany is quickly catching up to just name a couple of high tax usual suspects. UK also fits in this list.
Dubai as an example. Low taxes etc and if you go and work as an employee there it will fly for your passport country. If you go as an entrepreneur it will be frowned upon from the beginning. Depending on how big of a fish you are in the eyes of the tax authorities you will receive less or more attention. That threshold amount is a lot lower than we all think. It is definitely not in the millions anymore.
