I am a B permit holder, married with 1 child.

My wife and child live in the UK.

I live in Zurich, and my with-holding tax is 8%. Is this right?

Without knowing how much you earn how could we possibly know? I assume you will be taxed as a 'single' person in CH, as your family are still in the UK there is a reasonable chance that you will also need to do a UK tax return as you probably have not 'left the UK permanantly'.

My date rate is CHF 820 per day

My family are still in the UK, but I have left UK for a permanent role in Switzerland, travelling back to UK less than 90 days. So hope I do not have to pay the difference of the UK tax and the Swiss tax to UK, as thats the whole point of doing s stint in Zurich where beer is CHF 10 and the life is dull.

Your quoting a day rate, that does not sound like a permanant job, where you have a contract without end date.
The tax rate is very low for @17000 a month

Under current legislation you probably have not left as you have family & a property available to you. You need to break ties to the UK.
Under the proposed FUTURE regulations you would be OK

UK Tax is self assesment, you need to take advice

Thanks, what FUTURE legislation? Is the UK tax team going to make working overseas a gravy train again free of any UK tax lumps?

If you have a permanant job overseas & you work less than 20 Days in the UK & visit less than 90, you will be non resident in the UK for tax .

At present it's way more complicated as you have to 'leave' the uk, that means not having a family or house available, not haveing UK directorships & possibly even being a member of a club. It's based on Changing your lifestyle when you leave, not temporary absence.

For a single person earning 196,000 in Zurich I calculate a tax rate approx 20% If your wife & child were living her then nearer 15%.

You will get a tax return to fill in as you earn over 120K

If your going to groan at me for explaining your legal possition & calculating your CH tax rates I think I will refrain from helping you further.

so I am treated as single in Zurich even though my wife and son are in Surrey, England? That sucks. What if I let my house in the UK, and so, have no access to a house? As my wife doesn't work, so she could come here, and my son could go to boarding school in France.

You will then have to pay tax on the rental income as well as the asset value here in CH. And your wife can start complaining on the trailing spouses thread.

Why the groan, & you want more advice? Your wife & child need a permit here, then you can claim a deduction, however it will be credited againsted UK tax liability.

If you changed your lifestyle to that extent, you would probably be OK. Have you filled in a form to the UK revenue yet?

Once you fill in a CH tax return you will be taked on world wide wealth as well

EDIT you need to stop using a UK Dr if you have 'Left' the UK, de register & send back your medical card.
You also need to be out of the UK for 1 full tax year, so on the assumption you started your full time job in CH in May 2011 then you need to work until after 5 April 2012.

Another sucker not done any research...

Yawn..

Why can't you stop being aggressive when you ask for help? Try asking a Swiss accountant.

Did you notify the UK authorities amd apply to become none tax resident? If not then expect a tax return
