The return of the Mansion tax

The Liberal Democrats unveil their tax plans later today, and Nick Clegg insists that his radical plan will “put fairness back into the tax system”. It is expected to be a left of centre plan: don’t expect to hear anything about “savage cuts”.

The Mansion Tax is back, albeit in slightly more expensive clothes. The original proposal levied a 0.5% charge on properties valued at over £1million, which was a determined effort at suicide. Following criticism from senior MPs, staring nervously at their irate constituents, Clegg and Cable have raised the threshold to £2million and the levy to 1% – a humiliating retreat, revealing the dangers of making policy on the hoof.

Raising the tax income threshold to £10,000 is an attractive and fair policy; theoretically, a limited super tax is a reasonable way to fund the threshold hike. But, Clegg and Cable’s proposal remains laden with problems. First, what was proposed initially as a one-off levy has become a permanent measure, which is pernicious, not fair. It remains unclear how houses will be valued and it does not follow that because you own a £2million house you can afford a charge that will cost at least £5,500 per year according to Clegg. Crucially, the tax is unlikely to raise the required £11bn lost by raising the tax threshold. The Lib Dems’ position is fragile enough without having their key tax plan unravel under scrutiny.
