When George Osborne announced a cap on tax relief in the Budget last month, the so-called “tycoon tax” was supposed to be a populist measure. Under the plans, previously uncapped tax reliefs – including those on charitable donations – would be capped at £50,000 or 25 per cent of income, if higher. Supposed to be a way of clamping down on legal methods of tax avoidance, it clearly it hasn’t quite worked out as hoped, with the government under a hail of criticism for limiting charitable giving.

It appears that the storm is far from over, with a ComRes poll finding that two-thirds (65 per cent) of government backbenchers believe that tax relief on charitable donations should be exempt from the cap. The survey, commissioned by the Charities Aid Foundation, found that 68 per cent of the Conservative and Liberal Democrat MPs surveyed believed that the government should review its proposal to cap tax relief on charitable donations. It also showed that 93 per cent of coalition backbenchers believed that the government "should do all it can to use the tax system to encourage charitable donations from wealthy donors".

So what next for the policy? The government is still scrambling to regain some political points, with the Treasury releasing figures that reveal the extent of tax avoidance among the super-rich. The figures show that almost a thousand UK taxpayers earning over £1m a year are paying less than 30 per cent of their income in tax, while 12 of the 200 taxpayers earning over £10m are paying less than 10 per cent in tax. The figures are supposed to show how the super-rich are using tax reliefs and legal schemes to reduce the amount of tax they pay.

The numbers are certainly shocking, but at this point, probably not enough for the government to regain control of the message. Indeed, the Financial Times reports that Osborne is considering changes to the proposals, although as yet he is resisting pressure to exempt donations from the cap completely. Two proposals are reportedly under consideration. The first is to create a separate limit on charitable donations of 50 per cent of a person’s income, which would allow charities to claim tens of millions extra in tax relief than the current plan. Such a move would cost £40m, hugely reducing the amount saved by capping charitable donations, to just £20m. The second is to allow donors to roll over any unused tax reliefs into future years if they are used for donations.

Hot on the heels of the furores over pasties, granny tax, jerry cans, and email surveillance, this is yet another example of poor communication and media strategy from the very top of the coalition. With several papers this morning calling for David Cameron to improve his team, this latest incident only serves to cement the impression of a government that acts before it thinks.
