If you discover an error after filing electronically or wish to add information, you can correct your tax return using SteuerGo. The steps you need to take depend on whether a tax assessment notice has already been issued.
In addition, briefly inform the tax office that the new submission corrects the previous return and specify which details you have changed.
What applies if you receive a reminder despite having filed successfully?
An acknowledgement of receipt with a transfer ticket documents successful receipt on the tax administration’s ELSTER servers. A reminder therefore does not automatically mean that your return was not transmitted.
Provide your tax office with the acknowledgement of receipt and expressly ask them to check receipt and whereabouts using the transfer ticket. Please observe any deadlines set.
Do not resubmit your return solely because of a reminder. As a rule, you should only file again if changes are required or after expressly agreeing this with the tax office.
If you have already received a tax assessment notice, you should generally lodge an appeal within one month of notification if you wish to request changes. State the changes you would like to make. Resubmission alone does not replace an appeal lodged within the deadline.
