The government wants to know who owns businesses in the U.S., so they are asking businesses to tell them about their owners.
It's like when your teacher wants to know who's in your group for a project, but this is for big grown-up businesses.
If a business doesn't tell the government who owns it, they might have to pay a big fine, like $10,000!
This is because the government wants to make sure no one is doing bad things, like hiding money or selling things they shouldn't.
