The news that HMRC is sending letters to parents about Child Benefit has prompted a series of articles about the muddle and confusion that goes along with the process. On one hand, there seems to be popular support from opinion polls to the effect that richer people should not receive Child Benefit. (See e.g. the Daily Telegraph, 29th October.) On the other, there is confusion about inequity, how the rules will work, whether people are being asked not to claim, and so forth. The Institutes of Chartered Accountants think the whole thing is far too complicated. There is no contradiction here. The first statement is a question of principle; the second part concerns questions of practice. It is possible to make sure that richer people don’t benefit disproportionately by using the tax system, ‘clawing back’ the benefits. There is no possible arrangement for means-testing Child Benefit, or introducing special tax rules for one benefit on its own, that isn’t going to be complicated. “What I find so frightening”, Richard Titmuss once wrote, “is the extraordinary administrative naivety of those who argue in such terms for ‘selectivity’.” That same naivety is at root of the Treasury’s current problems.
