The combination of a frozen inheritance tax (IHT) nil rate band and considerably higher property values has pushed more estates into the IHT net. The average IHT bill is now nearly £62,000, with much larger amounts payable if an estate includes a property in London or the South East.

Increase in property values

Even though property prices have fallen recently, the average price of a detached house went up by more than £20,000 to nearly £454,000 during the year to March 2023. The average price for London property is not far off £525,000.
