Other taxpayers file a tax return and are taxed according to the standard taxation procedure.
Your employer - or your insurance or pension fund - deducts the tax at source from your salary (or benefits) every month and sends the money to the cantonal tax authorities. The tax deducted at source covers your federal, cantonal and communal income taxes. This means that you do not need to fill out a tax return.
