Quick Answer: What Is the Residence Nil-Rate Band?
The residence nil-rate band, or RNRB, is an additional inheritance tax threshold that may apply when a person leaves a qualifying home to direct descendants.
For the 2026–27 tax year, the maximum RNRB is £175,000. It is additional to the standard £325,000 nil-rate band, potentially giving a qualifying individual a total threshold of £500,000.
A qualifying surviving spouse or civil partner may potentially have combined thresholds of up to £1 million.
Key highlights:
- Maximum individual RNRB: £175,000
- Standard nil-rate band: £325,000
- Potential total for one qualifying person: £500,000
- Potential combined total for a married couple or civil partnership: £1 million
- The allowance is limited by the value of the qualifying home
- It is reduced when the net estate exceeds £2 million
- It is not automatically available to every homeowner
These figures are not automatic allowances for every homeowner. The available amount depends on the value of the qualifying home, who inherits it, the size of the estate and whether any unused allowance can be transferred.
Why Does the Residence Nil-Rate Band Matter to UK Families in 2026?
The RNRB matters because residential property often represents a substantial part of a family’s estate. It can reduce the amount exposed to inheritance tax when a qualifying home passes to children, grandchildren or certain other direct descendants.
Its importance has increased as the threshold has remained unchanged. HMRC’s February 2026 Trusts and Estates Newsletter states that the standard nil-rate band will remain £325,000, the RNRB will remain £175,000 and the taper will continue to start at £2 million until 5 April 2031.
rozen threshold does not itself increase the inheritance tax rate. However, if homes, investments or business interests rise in value while thresholds remain fixed, more of an estate may sit above the available allowances.
For business owners, the position can be particularly important. Shares in a company, commercial property, investments and a family home may together push the estate above £2 million, where the RNRB begins to taper.
What Are the Main Residence Nil-Rate Band Rules?
An estate does not qualify merely because the deceased owned a house. Several conditions normally need to be satisfied.
Core qualifying conditions:
- The deceased must generally have owned a home, or a share of one.
- The property must have been used as the deceased’s residence at some point.
- The home must form part of the estate, unless the downsizing provisions apply.
- The home must be “closely inherited”.
- The beneficiaries must usually be direct descendants.
- The allowance cannot exceed the qualifying value passing to those descendants.
- The allowance may be reduced when the estate exceeds £2 million.
HMRC’s guidance on checking eligibility for the additional inheritance tax threshold explains the qualifying-home and direct-descendant requirements in detail. The page was updated in April 2025 to reflect the move from domicile rules to the long-term UK residence regime for inheritance tax.
RNRB applies only against the estate on death. It is not a lifetime exemption, a property tax discount or a general allowance that can be used against any asset without restriction.
Who Qualifies for the Residence Nil-Rate Band?
Eligibility is determined by the deceased’s property, estate value, beneficiaries and inheritance arrangements.
What Conditions Must the Deceased and Estate Meet?
The deceased must usually have held a qualifying residential interest. This may be an entire home or a share of a jointly owned property.
The home does not have to be the deceased’s residence on the date of death. A former home may qualify if it was occupied as a residence at some point. Where the deceased owned several homes, the personal representatives may nominate one qualifying residence for the claim.
The available allowance is limited to the value of the qualifying residential interest that is closely inherited. A £120,000 qualifying share of a home cannot normally support an individual RNRB claim of £175,000.
Beneficiary and Inheritance Requirements
The property must normally pass to direct descendants through a will, intestacy or a qualifying trust arrangement. A gift to siblings, friends or a discretionary trust without qualifying descendant rights may fail the “closely inherited” test.
The wording of a will is therefore important. A will written before the RNRB was introduced may contain trust provisions that do not achieve the family’s intended tax result.
Who Counts as a Direct Descendant for Residence Nil-Rate Band Purposes?
Direct descendants include more than biological children. Qualifying beneficiaries may include children, grandchildren and other lineal descendants, as well as adopted children, stepchildren and foster children. Certain children for whom the deceased acted as guardian can also qualify.
Qualifying beneficiaries may include:
- Children and grandchildren
- Other lineal descendants
- Adopted children, stepchildren and foster children
- Certain children for whom the deceased acted as guardian
In some cases, the rules also extend to spouses or civil partners connected to those descendants:
- The spouse or civil partner of a direct descendant may qualify in certain circumstances
- A surviving spouse or civil partner of a descendant may also qualify where the statutory conditions are met
However, not everyone connected to the deceased will meet the definition:
- Brothers, sisters, nieces, nephews, cousins and friends are not direct descendants
- An unmarried partner of the deceased is not treated as a direct descendant simply because the couple shared a home
For example, a house left outright to a daughter may meet the descendant condition. By contrast, the same property left to a niece would not ordinarily qualify for RNRB, even where the niece was close to the deceased.
Which Homes and Properties Can Qualify for the Residence Nil-Rate Band?
A main home, former home or share of a home may qualify if the deceased occupied it as a residence at some point.
A property does not have to be the deceased’s principal residence for the entire ownership period. However, a buy-to-let property that was held solely as an investment and never occupied by the deceased would not normally qualify.
Only one residential interest can be used for the claim. If the deceased lived in more than one property, the personal representatives can generally nominate the property used in the calculation.
The RNRB is a UK inheritance tax rule, so it also applies to estates administered in Scotland. Scottish confirmation procedures and property law differ from probate procedures in England and Wales, but the central RNRB conditions and thresholds are set at UK level.
An overseas home may potentially qualify, although cross-border ownership and the long-term UK residence rules can make the analysis more complex.
How Is the Residence Nil-Rate Band Calculated?
The available RNRB is generally restricted to the lowest relevant figure: the statutory maximum, the qualifying property value, the amount closely inherited and the allowance remaining after any taper reduction.
Standard nil-rate band and residence nil-rate band – Allowance comparison:
| Feature | Standard nil-rate band | Residence nil-rate band |
|---|---|---|
| Maximum individual amount | £325,000 | £175,000 |
| Assets covered | Generally applies across the estate | Linked to a qualifying home |
| Descendant requirement | No | Yes |
| £2 million taper | No | Yes |
| Transferable between spouses or civil partners | Potentially | Potentially |
A qualifying individual may therefore have a combined threshold of £500,000. The estate must still satisfy the separate rules for each allowance. A worked residence nil-rate band calculation
Consider an unmarried parent who leaves a £400,000 home and £350,000 of other assets to two children.
Illustrative calculation:
| Item | Amount |
|---|---|
| Total estate | £750,000 |
| Standard nil-rate band | £325,000 |
| Potential RNRB | £175,000 |
| Combined potential threshold | £500,000 |
| Balance before other exemptions or reliefs | £250,000 |
At the usual 40% inheritance tax rate, the illustrative liability on that balance could be £100,000. The actual result may differ because of debts, gifts, exemptions, charitable legacies, reliefs and other estate circumstances.
When the Qualifying Home is Worth Less Than £175,000?
If the qualifying residential interest closely inherited is worth £120,000, the RNRB would generally be limited to £120,000. The statutory maximum does not create additional allowance beyond the qualifying property value.
There is no single GOV.UK calculator capable of resolving every RNRB case. Transfers, trusts, downsizing and estates above £2 million often require additional calculations.
How Does the £2 Million Taper Reduce the Residence Nil-Rate Band?
The RNRB is reduced by £1 for every £2 by which the relevant net estate exceeds £2 million. HMRC internal inheritance tax manual confirms this calculation.
| Relevant net estate | Excess over £2m | Reduction | RNRB remaining |
|---|---|---|---|
| £2,000,000 | £0 | £0 | £175,000 |
| £2,100,000 | £100,000 | £50,000 | £125,000 |
| £2,200,000 | £200,000 | £100,000 | £75,000 |
| £2,350,000 | £350,000 | £175,000 | £0 |
The taper test can affect estates containing valuable business interests or agricultural assets. Reliefs that reduce inheritance tax on particular assets do not necessarily reduce the estate value used for the RNRB taper calculation.
Gifting assets is not automatically a safe solution. Lifetime gifts can create seven-year-rule issues, capital gains tax consequences, loss of financial security and gift-with-reservation concerns.
Can Married Couples and Civil Partners Transfer an Unused Residence Nil-Rate Band?
An unused proportion of one spouse’s or civil partner’s RNRB may be transferred to the survivor’s estate.
HMRC summarises the rule plainly:
“Any residence nil rate band that’s not used when someone dies can go to their spouse or civil partner’s estate.”
transfer is based on the unused percentage, not simply the historic cash amount.
This protects the value of the transfer where the statutory RNRB changes between the two deaths.
A transfer may be available even if the first spouse or civil partner died before 6 April 2017, when the RNRB did not yet exist. The survivor’s estate must still include a qualifying home that passes to direct descendants.
A qualifying couple may potentially combine £650,000 of standard nil-rate band and £350,000 of RNRB. The resulting £1 million headline figure remains subject to the property value, inheritance conditions and taper rules.
Unmarried couples cannot generally transfer unused RNRB between their estates.
Which Residence Nil-Rate Band Forms Must Executors Complete?
Personal representatives are responsible for reporting the estate correctly and making any required RNRB claim.
Which HMRC Forms Are Used?
The main forms include:
- IHT435, used to claim the residence nil-rate band.
- IHT436, used to claim transferable RNRB from a deceased spouse or civil partner.
- IHT400, the full inheritance tax account where required.
- IHT402, used to transfer an unused standard nil-rate band.
HMRC’s IHT436 guidance for transferable residence nil-rate band claims says the form is used where RNRB is being claimed and a previously deceased spouse or civil partner left some or all of their allowance unused. Records and claim deadlines
Executors should retain the will, property valuations, ownership evidence, beneficiary details, marriage or civil partnership records and documents from an earlier spouse’s estate.
Where downsizing is involved, sale contracts, completion statements and evidence showing which assets passed to descendants may also be needed.
Transfer claims are subject to time limits. Executors should use current HMRC forms and instructions rather than relying on old estate-planning documents.
What Happens to the Residence Nil-Rate Band After Downsizing, Selling or Gifting a Home?
Selling or downsizing does not necessarily remove the RNRB. A “downsizing addition” may preserve some or all of the allowance when a former home was disposed of and other assets pass to direct descendants.
HMRC’s guidance on downsizing, selling or gifting a home explains that an estate may qualify where the deceased moved to a less valuable property or ceased to own a home.
disposal must generally have occurred on or after 8 July 2015. The former home must have been capable of qualifying, and sufficient assets must be closely inherited.
The calculation compares the RNRB lost because of the disposal with the value of other qualifying assets inherited by descendants. It can apply where someone sold a home before moving into rented accommodation or residential care.
Because the formula can be complex, records of the former home, sale value and eventual inheritance should be preserved.
Key Takeaways
- The residence nil-rate band is worth up to £175,000 per person.
- It is additional to the £325,000 standard nil-rate band.
- A qualifying home must generally pass to direct descendants.
- The allowance is limited by the value closely inherited.
- It is tapered for estates above £2 million.
- Unused RNRB may transfer between spouses and civil partners.
- Forms IHT435 and IHT436 may be required.
- Downsizing or selling a home does not always prevent a claim.
- The thresholds are currently fixed until 5 April 2031.
The familiar £500,000 and £1 million figures should therefore be treated as maximum potential thresholds, not universal entitlements.
Conclusion
The residence nil-rate band can materially reduce inheritance tax where a qualifying home passes to children, grandchildren or other direct descendants. However, entitlement depends on more than home ownership.
Families must consider the property’s history and value, the wording of the will, the identities of the beneficiaries, the total estate value and any unused allowance from a spouse or civil partner.
For UK homeowners and business owners, frozen thresholds make regular estate reviews increasingly relevant. A plan that worked when asset values were lower may produce a different result today.
Frequently Asked Questions
Does everyone who owns a home receive the residence nil-rate band?
No. The property must qualify, and it must generally pass to direct descendants. The allowance can also be restricted by the home’s value or the £2 million taper.
What is the difference between the nil-rate band and the residence nil-rate band?
The standard nil-rate band generally applies across the estate. The RNRB is an additional allowance linked to a qualifying home inherited by direct descendants.
Is inheritance tax always due when a house is left to children?
No. Liability depends on the whole estate, available thresholds, exemptions, debts, gifts and reliefs. Leaving a home to children may support an RNRB claim but does not automatically exempt everything.
Can a stepchild benefit from the residence nil-rate band?
Yes. A stepchild can qualify as a direct descendant for RNRB purposes.
Can an unmarried partner inherit unused RNRB?
No. The transfer provisions generally apply only to spouses and civil partners.
Does a home placed in trust qualify?
It depends on the trust terms and the beneficiaries’ rights. Some qualifying trusts can meet the rules, while many discretionary arrangements may not.
Can RNRB be claimed when no house remains in the estate?
Potentially. The downsizing addition may apply where a qualifying former home was sold, gifted or replaced and other assets pass to direct descendants.
