It's income. Thus you are labile for income tax on this, however you will only pay this once - either in the UK or Switzerland. You might want to use your UK tax allowances and pay UK tax...

[added]: You can have your UK state pension paid into a Swiss bank account in CHF by the way. Tax would then be much easier in Switzerland only and it would appear on your Swiss tax declaration in the form of your (slightly) increased bank balance...

Thank you for your answer. The problem is as it a small amount, it's not taxable in UK.so should it be here

Your Swiss tax declaration must include all of your worldwide income, I think it says so on the first page.

Quite so, but you only pay tax once...

Thanks for this info

Agreed, but the question here seems to be if income falls under the tax threshold in the UK (roughly £6.5k pa) can that tax exemption also be used in Switzerland. I suspect the answer is no - the UK income will be added to Swiss and any other income and the tax rate in Switzerland will be based on the total.

All your questions can be answered here.. scott.campbell@asc-suisse.com I know he deals with all the UK funds right here in Switzerland. Good luck!

I suspect the UK tax allowances can be used and thus reduce the total tax payable in both countries...
