How much are the tax rates for sales over 10,000CHF in Switzerland/Europe?

[GranEleganza]

I have a question about taxes and taxation in Switzerland/Europe, when I make sales for example over 10,000CHF, I am obliged to declare taxes so as not to have tax problems, but how much would this % of fees and taxes be?

You should consult with a professional tax expert because tax rules vary from one country/region to another.
