For our German offering: No, you will not be required to file any documents related to the account transfer with the German tax office.

For our Austrian offering: The transfer to the new Scalable must be reported to the Austrian tax office via FinanzOnline until 7 January 2026. Otherwise, the transfer may be treated as a deemed sale, which could result in capital gains tax of 27.5% on unrealised gains.
Scalable Capital will provide a report in your Mailbox presumably two weeks after the transfer to support you with the tax filing via FinanzOnline.

Scalable Capital does not provide tax advice. Please check the Austrian Website for more details.
