This page summarises the practice communicated by the cantonal administration; it does not replace the official instructions that come with your tax return, or personal advice. Deadlines change from year to year: check them on your form. The terms in quotation marks are those of the cantonal form or software, in German. The data and contacts on this page may also change: we update it regularly, but rely on its update date and, if in doubt, check with the cantonal administration.
