...Copy and paste didn't work last time. Let's hope this makes more sense.
Schools with charitable status ARE IMPOVERISHING state schools! 
For each £100 donated to a private school with charitable status, its accountants will go to the public coffer (tax payers) and demand up to another £31.25 (Additional-rate payers).
This means that every £100 given to charity by a basic-rate taxpayer will cost the Treasury £25, £100 given by a 40 per cent taxpayer costs £50, and the same amount from an additional rate taxpayer, costs £56.25.
If, for example, Jeff Fairburn, the newly super-rich chief executive of housebuilder Persimmon, hands over £10m of his bonus to a private school with charitable status, his gift will (assuming it would all attract tax at 45 per cent) cost the Treasury — and hence the rest of us — £5.65m.
The phrase “Gift Aid” somehow suggests there is free money available. There is not.
If Mr Fairburn gave his £10m to his favourite private school, the rest of us would instantly be down the equivalent of 100-odd primary school teachers for a year.
The more goes in Gift Aid, the less there is left for public services.
Add in other state subsidies offered to official charities (business rates relief, VAT relief, exemptions from capital gains and dividend taxes) and the money redirected from the state to registered charities starts to add up: the subsidisation of the charitable sector in the UK costs well over £6bn a year.
