Yeah, this is the first I've heard of ownership information needing to be filed--but I don't have any LLCs to file for, anyway.
Reading what the AG said about it he seems to feel it's a major intrusion for the government to require identifying the owners. I think that's what this is about--exposing the shell corporations. And of course the people who are keeping dirty books won't like that.
Many jurisdictions like the UAE and Singapore also demand Beneficiary Ownership reports, but obviously that does nothing to prevent the countries from being used for shell corporations. Not to mention, you can get away with it by simply reporting your source of funds as a gift from a rando, complete with a fake letter that no one will bother going in detail to verify.
The bigger issue is knowing that it’s needed. I wouldn’t have known about it without seeing this post on HN.
