The tax identification number identifies you in the taxation procedure. The number can always be used to clearly assign tax returns, messages and correspondence.

The tax identification number is a "non-speaking number". This means that neither personal data nor the responsible tax office can be read from it itself.

Every newborn child and every new citizen is automatically assigned a tax identification number when they first register in Germany. It remains valid for a lifetime and does not change when moving or getting married.

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

You will receive the tax identification number by post to your registration address. A notification by telephone or e-mail is not possible for data protection reasons.
