But that's the thing, you don't pay yourself in cash - you move most of your expenses to the company (cars, houses, investments, pension payments etc), so that money is only touched by corp tax. You take out the bare minimum that you cannot reasonably claim as business expense, squeezing your taxable income all the way down. When you reach a point where that's not possible, either you are making way more than 150k or you have a poor accountant.
