Tax identification number allocation

The tax identification number is used for identification in the tax procedure. It enables a clear allocation of tax returns, communications and correspondence to the applicable tax case.

It remains valid for a lifetime and does not change when moving or getting married. The tax identification number is a "non-talking number". This means that neither personal data nor the competent tax office can be read from it.

Tax identification number when registering for the first time in Germany / Leaving abroad before 01.07.2007

When you register with your reporting authority, the latter forwards your data to the appropriate body for the purpose of assigning the tax identification number. You will be informed by the competent authority by means of a letter of notification about the assignment of your tax identification number.

Tax identification number for newborn children

Newborns also receive a tax identification number from the competent authority.

You did not receive a tax identification number?

You have not received a letter with the tax identification number within 3 months of your first registration in Germany or for your newborn child? You can then provide your personal data to the appropriate body. The Federal Central Tax Office will then contact the reporting authority and send you the tax identification number.
