Keeping the family home in the family is often a top priority. In England and Wales an extra Inheritance Tax (IHT) allowance — the residence nil-rate band (RNRB) — can reduce the tax bill when a main residence is left to certain descendants. Below I explain the basics in plain English and flag the situations where professional help is especially important.
What the residence nil-rate band does, simply
The RNRB is an additional nil-rate allowance which can apply when you leave your main home to qualifying direct descendants. It is available on top of the standard IHT nil-rate band for estates that meet the conditions (see GOV.UK for the detail) standard nil-rate band information and residence nil-rate band guidance.
Who counts as a qualifying “direct descendant”?
“Direct descendants” generally means a child or grandchild (this includes children who are legally adopted). The official guidance sets out the precise categories and the rules for other family relationships, so check the GOV.UK guidance if your situation involves stepchildren, foster children or more complex family relationships see guidance. Whether someone qualifies can affect whether the RNRB applies.
Key conditions in plain language
– The property must be your main residence at some point and be left to qualifying direct descendants on death. The government guidance explains the timing and ownership tests in detail residence nil-rate band guidance.
– The RNRB is intended to apply alongside the normal nil-rate band for IHT (the basic tax-free amount) — check the main IHT page for how these interact IHT basics.
– There are rules to protect the allowance if you downsized or sold your home after 8 July 2015 and later left other assets to descendants; the “downsizing addition” can preserve the allowance in certain cases — details are on GOV.UK downsizing and RNRB.
The £2 million “taper” — what that means
The RNRB is subject to a taper for larger estates. Once the value of an estate exceeds £2 million, the RNRB is reduced: it is cut by £1 for every £2 that the estate’s value exceeds £2 million. Because of this taper, estates above the threshold may receive a reduced RNRB or none at all — see the official guidance for the exact calculations and examples RNRB taper rules.
Other points that commonly matter
– Transferability: unused RNRB and unused standard nil-rate band can potentially be transferred between spouses or civil partners on death — this can be important for married couples and civil partners when planning how to leave the family home see guidance.
– Gifts and timing: gifts made within seven years of death may still have IHT consequences; you should consult the GOV.UK guidance on gifts when assessing historic transfers of property gifts and IHT.
– Trusts and ownership: placing a property into a trust, or owning it jointly in certain ways, can affect eligibility for the RNRB and the IHT position generally — trusts have their own IHT rules and can be complex trusts and IHT guidance.
Illustrative composite scenario
A couple own a home and intend to leave it to their two grown children. They could be eligible for the RNRB to reduce IHT if the home is their main residence and all other conditions are met. If they later moved to a smaller property or set up a trust, the downsizing and trust rules might change the outcome. This is an illustrative composite scenario: for your own circumstances, get independent, regulated advice.
When to get professional help
If your family situation is straightforward (a single main residence passed directly to children), the RNRB can be fairly simple to apply. However, you should seek independent regulated legal or tax advice if you have:
– properties held in trust, in someone else’s name, or jointly in complex ways;
– downsized or sold your home since 8 July 2015 and still plan to leave assets to descendants; or
– a blended family or complicated care/parenting history where the status of stepchildren, foster children or adopted children might affect entitlement.
Practical next steps
– Check whether your home has been your main residence and who would be the qualifying beneficiaries; read the RNRB guidance residence nil-rate band guidance.
– Review your will, property ownership and any gifts or trusts with a solicitor or regulated tax adviser.
– If you’re approaching the £2 million estate threshold or use trusts, ask a specialist adviser to run the numbers and explain the downsizing and transferability rules.
– Keep clear records of property transactions and legal arrangements that could affect the IHT position.
