When Income taxes are paid in Switzerland?
Income and wealth taxes are periodic. So for the tax period of year 2020, the assessment is done in 2021. The tax assessment period is decisive for calculating and assessing the taxes.
The assessment is done based on the tax return (self declaration document) that taxpayers have to complete and submit to the tax administration within the deadlines outlined by the canton, many cantons offer extension for submit tax returns, completely at their discretion and in case by case basis.
The number of high taxes levied in Switzerland can appear high at the first look but if compared with other countries within EU or other developed countries, Switzerland does not stand out at all. The main difference between Switzerland and other countries if the absence of a uniform legislative regime that applies to the entire territory for the individual taxes. Only direct federal taxes are uniform and apply for the whole country.
