A reason to not take on your profit is that your "cost of sales" can be a pretty nebulous concept. How much of your 99M costs is licensing to entities you control in other jurisdictions?

I understand why it is fairer have it be profit, but profit in the modern accounting world seems to be a strange thing. A good accountant can make your profit be anything you like, so it doesn't make sense to tax based on the idea that company has bad accountants. Generally it is harder for accountants to change revenue figures (other than defer into different years).

The rules lawyering as to what is a legitimate cost is huge.
