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 – 2021
After the tax year 2020/2021 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.
