The inheritance tax nil-rate is currently set at £325,000 until April 2026 and will remain at this rate for a further two years until April 2028.
The residence nil-rate band will continue at £175,000, and the residence nil-rate band taper will still start at £2 million.
Qualifying estates will still be able to pass on up to £500,000, with the qualifying estate of a surviving spouse or civil partner remaining at £1m without inheritance tax liability.
The threshold freeze is seen by some as a way to increase inheritance tax bills without directly changing the rate. Due to the increase in house prices, more and more people will face higher inheritance tax bills when dealing with an estate.
Data published by HMRC in October showed a £400m increase in inheritance tax income when compared to the same time the previous year. These measures will be legislated by the Government in the Autumn finance bill.
