IHTM46022 | Calculating the RNRB: terms used: 'residential enhancement'

The RNRB for each individual is referred to as the ‘residential enhancement’. The value of the residential enhancement for deaths in the following tax years is:

• £100,000 in 2017 – 2018

• £125,000 in 2018 – 2019

• £150,000 in 2019 – 2020

• £175,000 in 2020 – 2028

After the tax year 2027/2028 these values will automatically increase each year by reference to the Consumer Prices Index (CPI), unless the Treasury specifies an alternative value – IHTA84/S8D(6, 7 & 8).

These sums can effectively be doubled where the full brought-forward allowance (IHTM46040) is available.
