Foodunit, I think you are missing my point.
I do think people should pay tax, and as Minitheminx said, the reason people with more money should pay more tax is because they can.
However, an accountant can give you advice, but they will not make decisions for you. I completely agree that people have an obligation to pay tax, but for many people the amount they should pay is not clearcut, and they also have to consider the impact of tax payments on cash-flow and their ability to trade.
By "helping the chancellor", I was talking about somebody overpaying tax in error, not somebody just paying tax.
I would generally support higher taxation/more government spending. However, I don't think this argument is helped by a tendency on the part of some people to demonise higher rate tax payers and assume that anybody who has to plan how much tax they pay is vulgar/on the fiddle, and that there is never any link between having more money and working hard and being innovative.
This way of thinking is about as helpful as assuming that all benefit claimants are feckless and fraudulent and that anybody in a minimum wage job just needs to try harder.
There are huge levels of (private) capital that could be invested into growth and job creation.
There are government schemes that encourage individuals to do this by giving them tax breaks on income tax and capital gains. Of course you have to be vulgarly thinking about tax planning to be aware that they exist.
