Taxes and other deductions for self-employed in Geneva
I am currently registered as an independent translator in the Czech Republic, but will shortly be moving to Geneva where my wife is posted.
Can anyone tell me very approximately what proportion of gross earnings one would expect to retain after taxes and other compulsory deductions in Geneva?
For example, if one invoices the equivalent of 4,000 Swiss Francs per month, how much of this would one pay in taxes, "social security", etc.?
Please excuse me if this question is overly simplistic (or has perhaps already been asked). I am just looking for a rough estimate, assuming that one takes whatever standard deductions might be available, without itemizing one's expenses.
(I am assuming that one has to declare oneself in Geneva if one lives there for more than 6 months of the year or does this rule perhaps only apply to EEC countries?)
