Nothing of what you're saying makes any sense.

> Income is the only reliable thing you can tax.

Then why does every country on earth tax corporate profit, not income?

> Why an Earth should governments employ entire teams to second guess internal bookkeeping?

Because that's how you make sure companies pay their taxes? Because it's a net gain to employ those teams because they find much more tax cheating than it costs to employ them?

> If a company is taking £billion out of a nation's spending power

Companies don't. They take cash and in return provide services that are even more valuable. The entire idea of free trade is that it's positive-sum for all.
