You'd tax global profit based on the local revenue fraction. So if the corporation has global profits of 1M and the revenue is 90% in country A and 10% in country B, then country A taxes 0.9M of profit and country B taxes 0.1M of profit and neither has to care where the corporation is located 'for tax purposes'.

> If your company cannot pay 1% of the revenue you don't have a viable business. Average corporation spends more on accounting and consulting.

Accounting costs banks and oil companies around 0.8%, so the will be fine.

I don't remember the exact number.

Revenue is simply what you earn regardless of your costs. If some kind of business generates lots of revenues but has costs that are similar, then...they are screwed. You are basically proposing taxing money that moves through any company, regardless of the amount of money that has to pass out of it. Many companies just couldn't afford to exist anymore, we'd go back to hunting and gathering because even farming would no longer be economically viable.

Oil companies have huge capital costs to find and extract resources, if you look at what their profits are compared to their costs of doing business, then obviously taxing revenue isn't going to work.
