    Which documents do you need?

    See our checklist (PDF). Clear photos are enough – whole page, little shadow.

    How secure is the upload?

    The transfer is encrypted (HTTPS). Your files are stored on servers in Switzerland and used only for your tax return. The number only allows dropping off files – nobody can view or download anything with it.
