Tax identification number, allocation to refugees and asylum seekers (BZSt)

With the introduction of the tax identification number (IdNr), the Federal Ministry of Finance and the Federal Government want to simplify the taxation process and reduce bureaucracy.

Detailed description

Refugees and asylum seekers are also assigned tax identification numbers by the Federal Central Tax Office.
This takes place in an automated process that is triggered by registering the person with the competent registration authority of the place of accommodation.

The assignment of a tax identification number is not associated with any further tax determinations, nor does it provide information about the status of the refugee. In particular, it does not contain any statements about the residence title or about a work permit. For more details see links.




  • A domestically registered resident

Documents required


Please note

The local tax offices cannot issue tax identification numbers and cannot influence the allocation process of the Federal Central Tax Office.

The registration offices are responsible for changing the civil status data in the register (e.g. marriage, birth).




The identification number (IdNr) will be sent to you automatically by letter from the BZSt after your birth or when you move to Germany from abroad for the first time, as soon as the registration authority has sent the required data to the BZSt.

Processing time

It may take up to 4 weeks for your IdNo to be communicated.

When registering for the first time in Germany or after birth, shipping can take 4-8 weeks.

If it has not been sent after 3 months, it is also advisable to submit a written application to the BZSt, stating the required data.
