We would like to inform you once again about the tax dates for the current year 2023. The enclosed overviews contain the most important and most common deadlines under the provisions currently in force.
As usual, some dates may still be subject to changes at short notice. We will inform you of such changes in good time.
The enclosed overviews are structured as follows:
1. Deadlines relating to recurring tax dates (Annexes 1A, 1B, 1C)
2. Deadlines relating to specific tax dates
3. Pension contributions of craftsmen and traders
4. Insurance contributions for commercial agents
5. Tax assistance form 730/2023
We already recommend that you note the deadlines which concern you accordingly in your calendar.
Please note that we have primarily taken into account deadlines of a tax nature. Accordingly – with few exceptions – deadlines arising from social security legislation or from other provisions are not listed.
