Inheritance Tax (IHT) applies to (some) wealth that is transferred on, or shortly before, death. The tax is currently charged at 40%, with each individual receiving an allowance of £325,000, before the tax is applied. Any unused proportion of this allowance is transferable to a surviving spouse or civil partner, effectively doubling the inheritance tax threshold for many couples. An Institute of Fiscal Studies (IFS) observation published last year considered the case for radical reform of IHT.
According to the IFS, the Conservatives have considered introducing a new £175,000 per person transferable allowance for main residences when they are passed to children or grandchildren. For many couples, this will give a total allowance of £1 million (£325,000 plus £175,000 each). This new allowance will be tapered away from those leaving more than £2 million with the intention that those leaving more than £2.35m will not benefit from the new allowance.
The IFS states that the vast majority of estates (over 90%) are not liable to IHT at the moment and therefore would not benefit. The Conservatives estimate that their policy would be a giveaway of about £1 billion. With around 50,000 estates forecast to pay IHT over the next few years this gives an average (mean) gain per IHT paying estate of around £20,000. The maximum reduction in IHT on a couple’s estate is £140,000 which will go to married couples with estates worth between £1 million and £2 million. Since the children of those with very large estates are disproportionately towards the top of the income distribution, the gains from this (and in fact any) IHT cut will also go disproportionately to those towards the top of the income distribution.
Many features of the policy are similar to one analysed in a Treasury (HMT) document that was leaked to, and published by, the Guardian in March 2015. This estimates that, based on Budget 2014 forecasts, the policy would reduce the proportion of estates liable for IHT from 8% in 2015–16 to just over 6% by the end of the parliament, rather than see it rise to just over 10% under current policy.
The IFS comments that this HMT document argues: “there are no strong economic arguments for introducing an inheritance tax exemption specifically related to main residences”.
The IFS also points out that the document lists a number of problems with the policy, for example: the fact that it would encourage investment in owner-occupied housing rather than other more productive investments and discourage downsizing late in life when that might otherwise be appropriate.
An alternative policy has been mooted to simply increase the existing threshold from £325,000, although the chance of this realistically being implemented, considering that the current policy is set to be frozen at this level (which is the level it was at in 2009–10) through to 2017–18, is uncertain to say the least.
