That will be CHF 40,000 ($40,000). Please pay by tomorrow. In cash.
Ok. That's not exactly how Swiss taxes go, but essentially, you get a bill from the tax man for a staggering amount and are expected to hurry up and go transfer the money to them asap upon receiving your bill. Taxes are not deducted directly from paychecks in Switzerland, Swiss residents are expected to save part of their paychecks for the big tax bill that comes later, once a year.
Can you imagine this working in the United States? Please. The budget deficit is bad enough.
