Besides that, all of our policies and national decisions are still heavily influenced by Germany like most EU countries.
Yesterday I got an alert that I was on the last day to file my taxes (if I didn't want to pay a €25 late-filing fee). On my lunch break I SSO'd into the tax agency website, which showed me a pre-compiled form with all the mortgage payments and medical expenses I'd made during the year already deducted, plus a house renovation expense that was registered but not automatically deducted because the system couldn't automatically determine if it qualified. I didn't have to insert any data, except for updating my email address as it still had my old GMail one. I saved it and submitted the tax form as-is, just in case.
Later that evening, I googled around a bit and determined that the renovation work did indeed qualify for the deduction. I reopened the website, clicked on 'Submit Corrective Tax Form' and entered the expense amount. I needed to provide the cadastral reference IDs for the renovated building/s, so I opened my tax agency home page -> Cadastral Query and copy-pasted them from it. Five minutes later I had submitted the second tax form and had two copies in my inbox: one in PDF, and one in RPF (its native columnar file format, in case I wanted to edit it later with a Java desktop application).
Here's the thing, though:
As little as five years ago, all of that would have required me to personally keep a bunch of paper trails and most likely professional help. "Cadastral query" was a by-word for "ponderous bureaucratic mess" and the practical advice was to start filing your taxes at least a couple months in advance.
However, once public-services SSO ("SPID") was introduced in 2015, it enabled a cascade of formerly in-person services to go full digital relatively quickly, because the most critical hard part - authn/authz - was solved. I think Germany should be perfectly able to shake off its dead-tree culture if it clears the same hurdle.
I report two examples here. When I moved to Germany two years ago, I was able to register in the official list of Italians living abroad ("AIRE") and to cancel my previous residence in Italy just by using "SPID" SSO on the Italian Ministry of Foreign Affairs website. Moreover, last week I was able to pay my parents' Italian car tax through an app on my smartphone.
On the contrary, last month I had to extend my driving license and I decided to get a German one. I've been told at the Driving Licence Department that I need to provide a document to show what country I come from ("Initial entry registration in the Federal Republic of Germany"). There was no way to provide such document other than going to the town hall of the first place where I lived after arriving in Germany two years ago, asking for such document, getting the paper copy after paying, and bringing it to the town hall of the city where I currently live. The trip only took about an hour, but I wonder how I could have done if I lived on the other side of Germany.
The funny thing is that my friends in Italy think that I moved to a super efficient country where everything is the top of innovation and digital technology (classic German stereotype among Italians) while none of this is possible in Italy and queuing at some public office is the only way to get these services done.
