Earlier quoted context omitted.
I'm not big on reporting, but arguing that the report is burdensome for small businesses is laughable. The BFOI takes 5-10 min to complete.
For you and I and everyone else on HN, the report is indeed trivial. For many other small businesses, it is not. There are millions of businesses which still operate largely on paper invoices and registers. Owners can't understand the text of the BOI website or the technical requirements, which includes registering for Login.gov. Others are completely engrossed in their day to day operations and won't even hear about…
It's literally just the names and govID numbers of the beneficial owners. All the info you need is a picture of the driver's license for each owner. That's it. Not a single figure. No percentage of ownership or shares etc. Requires absolutely zero accounting.
Also, the website requires no login, lessening the burden. (Actually for a gov website I thought it was pretty well designed, with clear help/explanations, etc.)
Your accountant is souping it up.
