In the wake of the 2015 General Election, the Conservative Party confirmed it would deliver on its Manifesto promise that parents

could pass their property up to the value of £1m to their children free of Inheritance Tax, thanks to a new ‘family home allowance’.

The allowance is called the Resident’s Nil Rate Band (RNRB) and takes effect in April 2017. By 2020/21 it effectively adds

£175,000 to each parent’s nil-rate band (currently £325,000) in respect of their main residence, bringing the total that may be

transferred IHT-free on the second death to £1m.

Basic rules

An estate will be entitled to the RNRB if:

  • the individual dies on or after 6 April 2017
  • they own a home, or a share of one, so that it is included in their estate for Inheritance Tax
  • their direct descendants, such as children or grandchildren, inherit the home or a share of it
  • the value of the estate is not more than £2m (estates valued at more than £2m the RNRB (and any

transferred RNRB) will reduce by £1 for every £2 over the £2m taper threshold. This means that in the tax year 2020 to 2021, an individual would not be entitled to the RNRB if their estate is worth more than £2,350,000.) 

An estate will also be entitled to the RNRB when an individual has downsized to a less valuable home or sold or given away their home after 7 July 2015, provided the deceased left the smaller residence or assets of equivalent value to direct descendants.

The RNRB allowance

The maximum amount of RNRB will increase every tax year as follows:

  • 2017/18 £100,000
  • 2018/19 £125,000
  • 2019/20 £150,000
  • 2020/21 £175,000

For later years, the amount of the RNRB will increase in line with the Consumer Prices Index. Any unused RNRB can be transferred to the deceased’s spouse / civil partner’s estate. This can also take place if the first of the couple died before 6 April 2017(even though the RNRB wasn’t available at that time).

The definition of direct descendant

For RNRB purposes, a direct descendant of a person is:

  • a child, grandchild or other lineal descendant of that person
  • a spouse or civil partner of a lineal descendant (including their widow, widower or surviving civil partner)
  • a child who is, or was at any time, that person’s step-child
  • an adopted child of that person
  • a child who was fostered at any time by that person
  • a child where that person is appointed as a guardian or special guardian for that child when they’re under 18
