Well, maybe not forced as in "win in front of the courts" but I think they will definitely try to send out their questionnaires and try to create an atmosphere or fear in hope some people will give them data and tax money without being forced to. If you fight back hard, they might drop it or actually try to make an example.

But then I remember in 2015, they ordered a tax audit based on the fact that the capital gain on one of my private capital based life insurances in Germany (with a tiny 4 digit EUR amount in value and being dormant for years) was reported wrongly by our payroll services. SKV enforced a full review and after months of back and forth with my tax lawyer which did cost me (or better my company) thousands of dollars in lawyer fees they send me their decision: I had to pay 93 SEK in taxes for the previous 3 years. No joke. Which shows, they can be unrelenting.

Why do you think so, what is so special about those younger members? To be honest, I do not read in that forum too often.
