Common questions
- What is the deadline to object to a tax assessment in French-speaking Switzerland?
- 30 days from notification, in writing to the authority named in the notice of appeal (Art. 132 para. 1 DFTA; Art. 48 of the Tax Harmonisation Act; in Geneva art. 39 LPFisc). The period starts the day after notification and cannot be extended; handing the letter to Swiss Post on the last day is enough (Art. 133 para. 1 DFTA). If you prove an obstacle — military or civilian service, illness, absence abroad or another serious reason — you may still object within 30 days after it ends (Art. 133 para. 3 DFTA).
- Does one objection cover both cantonal tax and federal direct tax in French-speaking Switzerland?
- Name each decision you contest: an objection to the cantonal and communal taxes does not automatically count for the federal direct tax. In Geneva, a court did not accept that a letter aimed at the cantonal notice (bordereau) alone also contested the federal tax. If both decisions were notified together, this letter covers both; if on different dates, each has its own 30 days — send an objection for each.
- What does a tax objection cost in French-speaking Switzerland, and what comes next?
- The objection procedure is usually free of charge (Art. 135 para. 3 DFTA). The authority re-examines the whole assessment and, after hearing you, may also change it to your disadvantage (Art. 135 para. 1 DFTA). Its decision can be appealed within 30 days to a body independent of the tax administration, for the federal direct tax under Art. 140 DFTA and for the cantonal and communal taxes under Art. 50 of the Tax Harmonisation Act and cantonal tax law: in Vaud to the Tribunal cantonal, in Geneva to the Tribunal administratif de première instance. The tax falls due despite the objection (Art. 161 para. 5 DFTA), so pay at least the undisputed part.
