I think a tax official would run straight into the “Microsoft problem”.
[So named because former Microsoft staff used to be famous for setting up tech businesses that subsequently failed.
Why?
Well, because to start up your business, you have to do a lot of things. Tax, office management, IT, marketing, sales… the list goes on and on.
Microsoft - like most big organisations - goes to enormous lengths to ensure that most of their employees don’t even need to care about any of that stuff. They just come into work, do their job and leave. Most of them have no idea what else is going on, and a good number would actually hold those other business units in some contempt (while completely ignorant of the fact that the departments they’re holding in contempt work together to keep the whole sausage machine running)]
