We cannot precisely say how long it takes to process your tax return. On average, you have to wait about 6-12 weeks to get your tax assessment sent by mail.
If, after four months, you still have not heard anything from the tax office, you can check and inquire as to the status of your submission. The most effective way to do this is via e-mail to your tax office with the transmission protocol attached.
If you prefer a phone call, it is best to speak to the so-called ELSTER representative and use the “Telenummer”.
You will find this number in your tax return as a PDF within the app:
Open the Taxfix app and log in.
Select the tax year for which you have submitted your tax return.
Click on “Your tax return” and then on “Submitted PDF”.
Starting on page 2 on the PDF document, you can find the “Ordnungsbegriff” at the top of the page. The “Telenummer” consists of the last three digits of this keyword.
