> This guide outlines the rules governing the UK Residence Nil-Rate Band (RNRB). You will learn how to pass your family home to descendants tax-free, understand tapering rules for larger estates, and see how to transfer unused allowances between spouses to maximise tax relief.

The Residence Nil-Rate Band is an additional inheritance tax allowance in the United Kingdom that applies when you pass your main home to your direct descendants upon death. By meeting the statutory criteria, you can secure up to an extra £175,000 allowance, saving your estate up to £70,000 in tax. If married or in a civil partnership, you can combine your allowances to pass on up to £1 million entirely free of inheritance tax.

## Key takeaways of the residence nil-rate band

Understanding the core parameters of this tax allowance helps with long-term financial planning. The following list outlines the essential rules, limits, and statutory freezes governing the policy:

1. The individual Residence Nil-Rate Band is fixed at £175,000 per person.
2. The value of the allowance is legally frozen at this level until 5 April 2031.
3. This relief can only be applied against the value of one residential property that the deceased lived in as a home.
4. The allowance is completely tapered to zero for estates exceeding £2.35 million.
5. Any unused allowance can be transferred to a surviving spouse or civil partner, doubling the potential relief to £350,000.

## How does the RNRB work when leaving a home to children?

To qualify for this tax relief when leaving a home to children, the deceased's estate must meet three core statutory conditions on death.

According to section 8E(1) of the Inheritance Tax Act 1984, the allowance is only applicable if specific elements are satisfied. First, the estate must include a qualifying residential interest, which is a dwelling-house that the deceased occupied as a residence at some point in their ownership. Second, this interest must be closely inherited, meaning it is passed directly to the deceased's children or other lineal descendants on death. Third, the deceased must have died on or after 6 April 2017, which was the official commencement date for this additional residential allowance.

## What is the Residence Nil-Rate Band?

The Residence Nil-Rate Band is a UK inheritance tax allowance that works alongside the standard nil-rate band to reduce or eliminate estate tax on family homes close to death. It provides an extra threshold specifically for residential property, meaning that portion of the estate attracts a zero per cent tax rate.

Under the provisions of section 8D(2) of the Inheritance Tax Act 1984, this tax-free allowance acts as an overlay on top of the standard £325,000 allowance. This means that if you qualify, your combined tax-free threshold increases significantly, allowing you to shield more of your wealth from the standard forty per cent inheritance tax rate.

## What are the RNRB and NRB thresholds for 2026/27?

The limits for both allowances have been explicitly fixed by the government to manage tax revenues over the coming years.

| Tax Allowance Type | Individual Limit | Legislated Freeze Date |
| --- | --- | --- |
| Standard Nil-Rate Band (NRB) | £325,000 | 5 April 2031 |
| Residence Nil-Rate Band (RNRB) | £175,000 | 5 April 2031 |
| Combined Single Threshold | £500,000 | 5 April 2031 |
| Combined Married/Partner Threshold | Up to £1,000,000 | 5 April 2031 |

## Who counts as a direct descendant for the RNRB?

A direct descendant is a lineal relative of the deceased who legally qualifies to closely inherit the home under the tax rules.

Section 8K(1) of the Inheritance Tax Act 1984 defines the specific categories of individuals who qualify as direct descendants. The qualifying categories are restricted to the following family relationships:

1. Lineal descendants of the deceased, which includes children, grandchildren, and great-grandchildren.
2. Step-children, adopted children, and children for whom the deceased was a foster parent.
3. The spouse or civil partner of a qualifying lineal descendant.
4. The unremarried widow, widower, or surviving civil partner of a lineal descendant who died before the deceased.

## How does the £2 million taper threshold reduce your allowance?

The residential allowance tapers down for high-value estates, meaning that wealthier individuals will see their tax relief completely removed.

According to section 8D(5) of the Inheritance Tax Act 1984, the allowance is reduced by one pound for every two pounds that the net value of the estate exceeds £2,000,000. The net value is assessed after deducting liabilities, such as outstanding mortgages and debts, but before applying any relief such as business property relief. Under this rule, a single person with an estate valued at £2.35 million or more will receive zero benefits from this extra residential allowance.

## Can you transfer unused RNRB to a surviving spouse?

You can transfer any unused residential allowance to a surviving spouse or civil partner, regardless of when the first partner died.

Section 8G of the Inheritance Tax Act 1984 establishes the rules for bringing forward unused allowances from a predeceased spouse's estate. If the first spouse to die did not use their allowance, perhaps because they left everything to their surviving partner, up to one hundred per cent of the unused pool can be claimed upon the second death. This claim must be made by the personal representatives of the deceased within two years of the end of the month in which the second death occurs.

## What is downsizing protection for the residence nil-rate band?

Downsizing protection allows individuals to retain their eligibility for the residential allowance even if they have sold their home or moved.

Under sections 8FA through 8FB of the Inheritance Tax Act 1984, this protection applies if you sold, downsized, or disposed of your qualifying home on or after 8 July 2015. If you subsequently died owning assets of lesser value, or if you moved into a care home, your estate can still claim an equivalent allowance value. The remaining assets must still be left to qualifying direct descendants in your will to satisfy the statutory rules.

## A worked example of calculating RNRB for a widow's estate

The following comparison demonstrates how a widow's £900,000 estate, which includes a home valued at £400,000, is calculated for tax purposes.

| Calculation Component | Applied Value | Notes and Source Rules |
| --- | --- | --- |
| Total Estate Value | £900,000 | Includes home and other personal assets |
| Personal Nil-Rate Band | £325,000 | Standard statutory threshold |
| Transferred Nil-Rate Band | £325,000 | Inherited from late spouse (100% unused) |
| Personal Residence Nil-Rate Band | £175,000 | Capped at property value |
| Transferred Residence Nil-Rate Band | £175,000 | Inherited from late spouse (100% unused) |
| Total Tax-Free Threshold | £1,000,000 | Combined standard and residential bands |
| Taxable Inheritance Amount | £0 | No balance remains after allowances |

## What traps should you avoid to preserve your RNRB?

There are several legal and financial arrangements that can unintentionally nullify your ability to use this valuable tax relief.

1. Leaving your home to a discretionary trust, which prevents the property from being classified as closely inherited.
2. Failing to account for outstanding mortgages, as only the net value of the equity in the home qualifies for relief.
3. Neglecting forthcoming pension changes in April 2027, which will drag pension funds into the estate and may trigger tapering rules.
4. Gifting the home during your lifetime while continuing to live there, which violates gift with reservation of benefit rules.

### Can you claim the residence nil-rate band if you leave your property to siblings?

No, you cannot claim the allowance in this scenario. Siblings do not qualify as direct descendants under the definition of closely inherited found in section 8K(1) of the Inheritance Tax Act 1984.

### Does a property left to a discretionary trust qualify for the RNRB?

Generally, it does not qualify. Properties put into a discretionary trust are legally owned by the trustees rather than physical individuals, meaning the property is not treated as closely inherited by direct descendants.

### How does a mortgage affect the value of the residence nil-rate band?

An outstanding mortgage directly reduces the qualifying value of the home. The inheritance tax calculation applies only to the net equity of the property at death, not its gross market value.

### What happens to the RNRB if I have to move into a care home?

You can still access the allowance. Under the downsizing provisions of sections 8FA-8FB of the Inheritance Tax Act 1984, selling your home to move into care preserves your entitlement if you leave assets to direct descendants.
