If you lost your Steueridentifikationsnummer, you may ask the Finanzamt to send it to you by filling this form. You will receive a letter with your tax ID a month later. You can also visit the nearest Finanzamt to get it on the same day1.

The tax number (Steuernummer)

The Steuernummer, Steuer-Identnummer or St-Nr. is for freelancers and businesses. It's a 10 or 11 digit number, and has the format "12/345/67890". It's sometimes written in the unified federal format as "3012034567890", where the first two digits are the number of your Bundesland12.

You get a Steuernummer by filling the Fragebogen zur Steuerlichen Erfassung. You will receive your tax number by mail 2 to 4 weeks after submitting this form1. If it takes longer, you can call your local Finanzamt and ask for the number.

The Steuernummer is unique, but not permanent. It will change if you move to an area served by a different Finanzamt1. Do not confuse the Steuernummer with the VAT number (Umsatzsteuer-Identifikationsnummer1).
