While there will be no radical change to property taxes in this budget, ministers and officials are looking at the tally of winners and losers from the abolition of council tax and stamp duty.
They would be replaced with a proportional property tax, levied on the existing values of homes. Council tax is calculated on property valuations from 1991.
WPI’s analysis shows that the tax would be revenue-neutral — raising the same as council tax and stamp duty — if the levy were set at 0.48% of the value of a home.
That would mean someone owning a £150,000 house would pay £720 a year, just £60 a month. The average band D council tax in England for 2020-21 was £1,818. But a family in a £1m house would have to fork out £400 a month, or £4,800 a year.
Based on that figure of 0.48%, an owner of a £400k london flat like myself would be paying an extra £500 in tax per annum or around £40 plus quid a month so not the end of the world as opposed to Band C Council tax (my current band). However, the owners of £1 million properties would be the worst affected. And while most people on Mumsnet are probably not buyers of £1 million properties (though it is surprisingly common in certain areas), AIBU to think that people would think twice before offering a staggeringly high price for a property given that it would attract a permanent tax liability that would increase with price inflation and continue well into retirement.
The conventional wisdom here is that property is always a good investment as the mortgage would be paid off one day and council tax for Band D properties is not hugely dissimilar to smaller properties (my MIL in Band D pays hardly any more tax than me). However would you still think that if you would get hit with a property tax forever?
