How long is the objection period?

If the tax office has set the tax too high, you can appeal against the tax assessment. However, this is only possible until the end of the objection period.

The objection period ends one month after the tax assessment has been issued. The assessment is deemed to have been issued on the third day after it was sent by the tax office. If this day falls on a public holiday or weekend, the next working day is considered the date of issue. If the end of the objection period falls on a Sunday or weekend, the objection period ends on the next working day.

Even after the objection period has ended, it is possible to amend the tax assessment in exceptional cases, e.g. by applying for reinstatement of the previous status.
