When filing online using your own ELSTER certificate, you submit your tax return to the tax authorities securely and in encrypted form with SteuerGo. An additional printed copy with a signature and postal submission are not required.
Download the complete confirmation of receipt and keep it as proof of transmission.
What applies if you receive a reminder despite successful filing?
Present the confirmation of receipt to your tax office and explicitly ask them to check receipt and whereabouts using the transfer ticket. Please observe any deadlines set.
Do not resubmit the return solely because of a reminder. As a rule, a further submission should only be made if changes are required or after explicit agreement with the tax office.
If the tax office requests supporting documents, you can submit them via the electronic document submission service in SteuerGo.
