How do I get my tax identification number as a foreigner?
After you have registered with the residents’ registration office, you will receive your tax ID in writing from the Federal Central Tax Office (BZSt for short).
If you are not registered in Germany but are still subject to tax here because you earn income in Germany, you must report to your responsible tax office.
In this case it is not possible to apply for your tax identification number yourself. The tax office will request your tax ID from the BZSt on your behalf.
Who can access my data?
All data linked to your tax identification number may only be used by the tax authorities for reasons of data protection.
All other institutions, such as pension and health insurances, receive your tax ID but have no further access to the associated data.
