Registering for a tax number

Tax identification number

All individuals receive an 11-digit identification number to ensure their unique identification within the tax system. The number will not change if you move home or marry. It will remain with you for the whole of your life. It does not contain any information about you or the tax office responsible for your tax affairs.
The tax office will send you the tax ID automatically to your registered German address within three weeks after you’ve done your Bürgerbüro registration.

Please be aware that identification numbers are also allocated to children. This is necessary because liability for tax can begin at birth.

At your nearest department of public order.

Tax number

Each employee or self-employed person gets a tax number of the local Tax Office.
If you are employed by a company, your employer will automatically deduct the income tax from your gross wage/salary in the form of wage tax (Lohnsteuer) and transfer it to the local tax office on your behalf. Here you get the tax number automatically. Otherwise apply at the local tax office.

At your local tax office (Finanzamt)
