The problem I have with this argument, kitch, is that is the exact same argument used by the megacorps to avoid tax. And it's not a good argument however it is spun. Let's look at your own figures here:
So, since your business paid £25k in corp tax last year, it had about £100k in net profits to play with. And that's after all the rates, PAYE, VAT, NI stuff. All of which comes with the cost of doing business, so you can't go double-counting that.
Now, there's no particular god-given right for you take any of that profit out of the company without the same taxation regimes that apply to your employees. Never mind if it is "your" company, it is a different thing. If it is that much pain then disincorporate (but no, even more tax!).
Starbucks used the same argument "look how much we are contributing to the government" and then listing all the taxes paid by its employees, but the fact remains that if Starbucks were replaced by 700 independent coffee shops then (a) they wouldn't pay ridiculous licensing fees that extinguish their profits and (b) they'd end up paying more tax in gross.
I know exactly and painfully where you are coming from kitch, but I don't support it,.
