I heard something yesterday about how you can authenticate digitally for tax documents using the NFC chip in your Personalausweis! You just have to download some app.

But yes, in general, we’re SO CLOSE…then you have to go do Anmeldung with a paper form in person

I do all my tax return stuff online with my Personalausweis. Once you got all your PINs and access codes it's quite seamless actually. You can even pair your phone with your PC and use the phone's NFC reader to read the ID-card.

That stuff honestly improved quite a bit in the recent years. Most of these services are just not advertised or integrated enough so far.
