To open your Business Pocket, you need to provide us with the proof of profession. This is the official letter from the tax office mentioning your tax number (Steuernummer) and your activity. Alternatively, you can upload your chamber admission certificate, your university degree based on your activity, among others (check the full list here).
Some tips to upload your document successfully are:
Take a picture of the document in broad daylight to ensure that all the information is readable without reflections.
Create a pdf of the pictures/scans to include all the pages as a single document (if it has several pages).
Check that all the corners of the document are visible and that the image has a crisp, clear resolution.
When do I need to upload the official letter from the tax office or my proof of profession? You can submit any of these documents during the pocket creation or at a later point in time. Please make sure that the document is uploaded within fifty six days to avoid having your Business Pocket blocked.
Business Pockets are only available if you're a freelancer or self-employed in Germany.
