3. Bern's calendar and practice

   In the canton of Bern, tax matters are handled by the Bern Tax Office (Intendance des impôts du canton de Berne). Filing deadlines and extension arrangements follow the canton's own practice. Filings can be made in French.

   For individuals, the ordinary filing deadline is 15 March, and 15 May for the self-employed. An online extension can be obtained free of charge until 15 July, then subject to a charge of CHF 20 until 15 September and CHF 40 until 15 November, which is the final deadline.

   To challenge a tax assessment, an objection must be filed within 30 days of its notification.

   For withholding tax, the canton publishes two sets of tariffs, with or without parish tax depending on membership of a recognised church.
