Tax Identification Number (Tax ID) in Germany
Since 2008, every German citizen has been assigned a Tax Identification Number (Tax ID). This 11-digit number is issued by the Federal Central Tax Office (Bundeszentralamt für Steuern) and is a central element of the German tax system. Its purpose is to uniquely identify taxpayers and manage their tax affairs. Here is some important information regarding the Tax ID and the procedures you should keep in mind:
Receiving the Tax ID
As a rule, the Tax ID is automatically mailed to all citizens registered in Germany. You will receive a letter from the Federal Central Tax Office, where your Tax ID is clearly displayed in the upper right-hand corner. It is important to keep this number safe, as it is required for numerous tax-related matters.
Alternatives for Obtaining the Tax ID
If you have not received the letter containing your Tax ID or if the document has been lost, you have the option to request a self-disclosure (Selbstauskunft) of your Tax ID at your local Citizens' Registration Office (Bürgeramt). The staff there can issue a confirmation of your Tax ID for you to use.
Important Distinction
It is crucial that you do not use your Tax Number (Steuernummer) when asked for your Tax Identification Number. The Tax Number is a different identifier also used for tax purposes, but it must not be confused with the Tax ID. While the Tax ID remains valid for life, the Tax Number can change—for example, if you move or if your local tax office changes.
Tax ID for Those Not Registered in Germany
If you are not registered in Germany but receive income here, you must contact the relevant Tax Office (Finanzamt). In this case, you can apply for your Tax ID by notifying the tax office. They will then initiate the necessary steps to request your Tax ID from the Federal Central Tax Office (BZSt). It is important to provide all required documents and information to facilitate the process.
