Inheritance Tax on Property UK (2026): How It Works, RNRB & Reducing the Bill
Updated 13 May 2026 · 11 min read · England & Wales
Quick answer
Your home is valued at open market price on the date of death and forms part of your taxable estate. IHT is charged at 40% on the amount above your available nil-rate bands. The residence nil-rate band adds £175,000 per person (up to £350,000 for a couple) when the home is left to direct descendants — but it must be claimed via IHT435, and it is forfeited if the property goes into a discretionary trust.
How IHT applies to property
When someone dies, HMRC values their estate at open market value on the date of death — meaning the price a willing buyer would pay on the open market at that moment. For a main home, this typically requires an RICS surveyor’s valuation, which the executor instructs. HMRC has the right to challenge the figure if it appears artificially low.
The property value is added to all other estate assets (savings, investments, personal possessions, other property). IHT is then charged at 40% on the amount above the available nil-rate bands. The key allowances for 2026/27:
| Allowance | Amount | Condition |
|---|---|---|
| Nil-rate band (NRB) | £325,000 | Everyone — frozen to April 2031 |
| Residence nil-rate band (RNRB) | £175,000 | Home to direct descendants only |
| Combined per person (with RNRB) | £500,000 | Single person with qualifying home and descendants |
| Combined couple maximum | £1,000,000 | Married/civil partner, qualifying home, direct descendants |
The residence nil-rate band (RNRB) in detail
The RNRB is an additional £175,000 allowance that applies specifically when a qualifying residential property passes to direct descendants. It is on top of the standard £325,000 nil-rate band and can make an enormous difference: a couple who use both allowances fully can pass up to £1,000,000 free of IHT.
Who qualifies as a direct descendant?
Direct descendants include: biological children, adopted children, step-children, foster children, and their own lineal descendants (grandchildren, great-grandchildren). It does not include: nieces, nephews, siblings, or other relatives. A spouse or civil partner of a direct descendant does qualify, but only as the direct descendant’s spouse (not independently).
The £2 million taper
The RNRB tapers away for larger estates. For every £2 the net estate exceeds £2,000,000, the RNRB reduces by £1. At £2,350,000, the full £175,000 RNRB is eliminated. This taper is calculated on the net estate value before deducting the RNRB — meaning the taper threshold is lower than it appears.
The discretionary trust trap
Placing the family home into a discretionary trust in your will — even if all the potential beneficiaries are your children — forfeits the RNRB entirely. This is a common and expensive mistake, particularly in wills drafted before the RNRB was introduced in 2017. If your will contains a trust over your property, check whether it costs you the RNRB.
A life interest trust is the alternative: the property passes to direct descendants subject to a life interest for the surviving spouse. This preserves the RNRB while still protecting the surviving spouse’s right to live in the home.
Claiming the RNRB — IHT435
The RNRB is not applied automatically. Executors must claim it by completing HMRC form IHT435 alongside the IHT400. If the executor fails to submit the form, the relief is lost — HMRC will not prompt for it. Where the first spouse left unused RNRB, the executor of the second estate must also claim the transferred RNRB using IHT435.
How joint ownership affects property IHT
How property is legally held determines both what passes at death and the IHT implications:
| Ownership type | What happens on first death | IHT on first death | IHT risk on second death |
|---|---|---|---|
| Joint tenants (spouses) | Full property passes to survivor by survivorship | Nil (spouse exemption) | Full value in survivor’s estate — RNRB can apply |
| Tenants in common (spouses) | Deceased’s share passes via will (or intestacy) | Nil if share left to spouse; NRB may be used | Only survivor’s share in their estate — NRB efficiency preserved |
| Sole ownership | Full property passes via will or intestacy | IHT payable if estate exceeds NRB + RNRB | N/A (already dealt with on first death) |
The IHT-before-probate problem
IHT must be paid before HMRC releases the probate tax clearance — which must be obtained before the Probate Registry issues the Grant. But the house cannot be sold without the Grant. This creates a Catch-22:
- Solution 1: HMRC Direct Payment Scheme — most banks will release funds directly to HMRC before probate using this scheme.
- Solution 2: IHT on property can be paid in annual instalments over 10 years (interest-bearing) under s.227 Inheritance Tax Act 1984 — allowing the house to be retained until a convenient sale.
- Solution 3: An executor loan — some banks lend against the estate to fund the IHT before probate.
Strategies to reduce IHT on property
These work best when planned in advance and reflected in a correctly drafted will:
- Leave the home directly to direct descendants — unlocks the full RNRB (never into a discretionary trust).
- Hold the property as tenants in common with your spouse — preserves both partners’ nil-rate bands rather than the full property sitting in the survivor’s estate.
- Use a life interest trust — survivor retains the right to live in the home while the capital is ring-fenced for your children, preserving the RNRB.
- Make lifetime gifts with genuine occupation surrender — transfer the property, move out, and survive 7 years (note: gift with reservation of benefit rules must not apply).
- Consider equity release — reduces the property’s net value in the estate (the debt is an estate liability), though this has its own financial implications.
Frequently asked questions
How much inheritance tax is due on a house in the UK in 2026?+
IHT on a property depends on the total estate value, not just the house. The standard nil-rate band is £325,000 per person. If you leave your main home to direct descendants (children, grandchildren), the residence nil-rate band adds a further £175,000 — giving £500,000 per person (£1,000,000 for couples). IHT is charged at 40% on the amount above these combined allowances. Example: a sole owner with a £600,000 estate including their home, no RNRB claim, no spouse — taxable estate is £275,000, IHT = £110,000.
Does a jointly owned house avoid inheritance tax in the UK?+
Joint ownership reduces IHT exposure but does not eliminate it. If held as joint tenants, the property passes by survivorship to the surviving co-owner outside the will — but the full value eventually forms part of the survivor's estate on the second death. If held as tenants in common, the deceased's share passes through their estate (and is subject to IHT). Tenants in common with a life interest trust can be tax-efficient by preserving both partners' nil-rate bands.
Can I put my house in my children's names to avoid inheritance tax UK?+
Transferring your home to your children while continuing to live in it creates a 'gift with reservation of benefit' — HMRC treats the property as still forming part of your estate. The transfer must be a genuine gift where you give up occupation and benefit. If you move out and pay a full market-rate rent, the gift may become effective for IHT after 7 years. This is a complex area where professional advice is essential.
What is the residence nil rate band and how does it apply to property UK?+
The residence nil-rate band (RNRB) is an additional IHT allowance of £175,000 per person (2026/27) that applies when you leave your main home (or assets of equivalent value following a downsizing) to direct descendants. Your will must specifically direct the property to qualifying beneficiaries — children, step-children, grandchildren and further lineal descendants. The RNRB is not applied automatically: the executor must claim it via form IHT435. For couples, any unused RNRB from the first death is transferred to the survivor.
What happens if I can't pay the inheritance tax bill before probate UK?+
HMRC requires IHT to be paid before the Probate Registry will issue the Grant of Probate — creating a timing problem since bank accounts are frozen until probate. Strategies to bridge this: (1) Use the HMRC Direct Payment Scheme — banks release funds directly to HMRC before probate. (2) Take an executor loan (some banks offer interest-bearing bridging loans for this purpose). (3) Sell other assets first if the estate includes investments. Property itself cannot usually be sold before probate, but instalments over 10 years can be arranged for property-based IHT under s.227 IHTA 1984.
Does the RNRB apply if I leave my house to a discretionary trust UK?+
No. Leaving your home to a discretionary trust forfeits the residence nil-rate band entirely, even if the potential beneficiaries of the trust are all direct descendants. This is one of the most common and costly estate-planning errors. If you need flexibility (e.g. a blended family), consider a life interest trust instead — the property passes to a qualifying direct descendant with a life interest for a surviving spouse, which does preserve the RNRB.
Is there inheritance tax on a second property in the UK?+
Yes. All property in the estate — main home, buy-to-let, holiday home — is included at open market value at the date of death. The RNRB only applies to one qualifying residential property (your main residence or former main residence). Additional properties do not attract RNRB. Agricultural Property Relief may apply to farmland, and Business Property Relief may apply to properties used wholly for a qualifying business, but a standard buy-to-let does not qualify for either.
