Tax the Turnover
Don't tax the profits - the accountants are too sharp!
Make it a legal requirement that if you do business in the UK you must state your UK annual turnover.
Tax on the basis of the turnover. Profits may go anywhere, but the turnover in the UK you can't get out of.
Low turnover is bad for the share price.
Could do it a sliding scale, but the biggest companies will have the highest turnover.
Doesn't matter if they don't make a profit, you tax them on the turnover.
Means companies will pay their fair share
