Identification number
Enter here the 11-digit tax identification number that you received in writing from the Federal Central Tax Office.
Since 2009, the tax identification number for children must also be entered in the tax return. This information is required for data comparison with the child benefit funds and in the case of transfers.
For newborns, the Federal Central Tax Office (Bundeszentralamt für Steuern) will inform you of the tax identification number as soon as it receives the necessary data from the residents' registration office.
Note: You also have the option of requesting your tax ID again from the Federal Central Tax Office. The tax ID will then be sent to you by letter.
