Frequently asked questions

What is the difference between Steuer-ID and Steuernummer?
The Steuer-ID is permanent (11 digits), assigned automatically, and never changes. The Steuernummer (13 digits) is assigned by the local Finanzamt and may change if you move to a different city.
Can I work without a Steuernummer?
You can start working, but without the correct number, the tax office applies the maximum tax rate (Steuerklasse VI). Apply for it as soon as possible.
