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.
