Taking a strict legal view, it all depends on two concepts Residence and Domicle. There is basically three situations:

- The simple one is when you move here with all your family and give up your house etc. in the UK, in this case you are taxed here on world wide income.

- The next would be where you move here, but keep your house and perhaps some family members remain behind to attend school etc.. In such a case you are considered to have moved only on a temp. basis and you are taxed on your Swiss income here and all other income in the UK.

- Third case is where it is not clear! you have fees or salary coming out of the UK, you travel there every week to consult with your client and so on. In such a case the two revenue authorities must decide what is to be done...

You seem to fall into the third case, now this is the strict legal situation. You may do as you are suggesting and have no problems or you may come up against some young gun in the revenue that wants to make a name from himself and he decides to go after your world wide income and raise an assessment accordingly! If this happens then it could involve you in having to appealing the assessment and if I remember correctly you normally have to pay it and then appeal it!

Simple thing to do is just call the SWISS tax office and ask them, if they say go for it, then at least you have a basis for doing it and if the UK revenue come calling you can just point them in the direction of the Swiss guys and let them fight it out <g>.
