"Corporations, limited liability companies, and other similar entities formed in the U.S. or foreign entities registered to do business in the U.S. must now report their beneficial owners (any U.S. or foreign individual who owns 25% or more equity interest in a U.S. legal entity) to the U.S. Department of the Treasury."

Is this true?

I think companies with a physical office in the US, where they also have a operating presence, are exempt. But looks like you still have to report that you are exempt.
If you are not exempt, you need to provide your name, address, date of birth, and an ID. That is all.
At this point, it looks like FOIA is not applicable for this information, so privacy is not impacted.
