How does the Steuernummer work?

Your Steuernummer (business tax number) is allocated by your local Finanzamt office.

The number is linked to your location, as the first 2 digits are related to your tax office.

In the app, you can update your Steuernummer from the settings page. Make sure that your Steuernummer and State values match.

How to proceed when changing address?

When you move to a new location, you should contact the local Finanzamt office of your new location, who will allocate a new Steuernummer for you.

After you get this new number, you can update it as well as the matching state in the app settings.

In the meantime, keep your old state in the app settings and only update your address (except for the state)
