If someone's aim is to avoid a wealth tax, then moving to Switzerland (one of the few other countries with a wealth tax) seems like a confusing choice. The Swiss wealth tax is payable in some cantons from ~50k Euros.
Switzerland's wealth tax is a lot more reasonable though. UK is 2%, Norway is 1.1%, the Swiss ones are all below 1% (depends on your canton), ex the Zug canton is 0.21%.
All that matters is the total tax. You calculate the toes tax in Switzerland (including wealth tax) to that of Norway and then you may see itβs a clear choice.
