Very much depends on what happens in the budget in October and for subsequent years.
If - as some rumours suggest - there will be changes to inheritance tax and capital gains tax, then lots of houses could suddenly come on the market. One rumour is that CGT may be charged on inheritances, but with the death restart benefit removed. So, currently, if you inherit a house and sell it you’re charged CGT on the difference between the value at point of inheriting and the value at sale.
Apparently there are calls to change this, so the CGT tax is calculated on the difference between sale price and original purchase price.
So if someone bought a house for £20,000 in 1980 and it sells in 2024 for £260,000, the inheritor will have to pay CGT on £220,000. If CGT is aligned with income tax this is £44,000 at the 20% tax rate and £88,000 at 40%.
If IHT threshold is also reduced to £200,000 then additionally IHT would be charged at 40% on £60,000, so £24,000. For someone on the 20% tax rate they lose £68,000 and £112,000 on the 40% rate.
If IHT threshold is reduced to £100,000 then the IHT due is £64,000 and 20% tax inheritors lose £108,000 and 40% taxpayers lose £152,000.
If that happens then owning immovable assets such as property is going to be less attractive. Better to spend the cash on holidays and good food and wine and rent somewhere to live. This also frees up cash to give your children to spend as they wish - assuming a lifetime gift allowance doesn’t happen which is another rumour!!
If people stop buying houses then the housing stock will likely be purchased by local authorities who currently have far greater demand than supply. Large company landlords may also buy but that depends on any tax increases targeted at businesses.
Another alternative is that imposing such charges causes house prices to nosedive, but unless it’s a managed slow decline I’m not sure that’s a good thing for the economy or individual finances!
Alternatively, if wealthy keep moving home every few years so you never build up much additional equity on your house. That way there won’t be a big CGT bill for whoever inherits. But that isn’t feasible for those who can only just afford their mortgage as moving is expensive - stamp duty, solicitors fees, moving contractors etc etc.
So, in 20+ years time the hold of private property in this country could look very, very different from that today.
Sill, I’m sure someone clever has been thinking about this very, very deeply…
