Lost tax ID: Here’s what to do

If you’ve lost your personal tax ID, it’s no big deal. We show you how to find the number elsewhere and, if in doubt, apply for it again.

Lost tax ID: Find the number here

You once received the 11-digit tax identification number from the Federal Central Tax Office. However, the letter is not the only document on which you will find the number.

• Also take a look at your income tax card or your last tax assessment notice. The tax ID is also listed here.

If you keep your documents carefully, you may also find an information letter from your tax office from 2011. Your tax ID is also listed here.


Reapply for lost tax ID

• If you have gone through all the possibilities and still haven’t found what you are looking for, you can always contact the Federal Central Tax Office. Fill out the form completely with your data.
