Inheritance Tax Changes 2026 UK: Budget Updates, NRB Freeze and Pensions
The Autumn 2025 Budget locked IHT thresholds until 2031 and is about to drag pension pots into taxable estates. Here is what changed and what you need to do.
Key changes at a glance
- NRB frozen to April 2031: Nil-rate band stays at £325,000; residence NRB stays at £175,000.
- Pension IHT from April 2027: Unused pension pots will be included in your estate and subject to 40% IHT.
- Fiscal drag: As property prices rise, more estates will exceed the threshold automatically.
- Action needed now: Review pension nomination forms and update wills before April 2027.
Current inheritance tax thresholds (2026/27)
| Allowance | Amount | Frozen until | Conditions |
|---|---|---|---|
| Nil-Rate Band (NRB) | £325,000 | April 2031 | Available to all estates |
| Residence NRB (RNRB) | £175,000 | April 2031 | Must leave qualifying home to direct descendants; tapered above £2m estate |
| Single person max | £500,000 | — | NRB + RNRB combined |
| Married couple max | £1,000,000 | — | Both allowances transfer to surviving spouse |
Above these thresholds, inheritance tax is charged at 40%. If you leave 10% or more of your estate to charity, the rate reduces to 36%.
The NRB freeze: why it matters more each year
The nil-rate band has been frozen since 2009, when the average UK house price was around £162,000. The current average UK house price is over £290,000. As property values rise while the threshold stays fixed, more and more estates that would previously have been below the IHT threshold are now caught.
Extending the freeze to April 2031 means the nil-rate band will have been frozen for 22 years by the time it is next reviewed. A couple who bought a house in the 1980s for a modest sum may now find their estate is well above the £1,000,000 combined threshold once the RNRB conditions are not met.
The pension IHT bombshell: April 2027
Currently, defined contribution pension pots pass completely outside your estate for IHT purposes. This has made pensions a highly efficient inheritance planning vehicle — leaving pension funds to pass to children while spending other assets first.
From April 2027, unused pension funds will be brought into a person's taxable estate. The Government announced this in the October 2024 Budget, with implementation deferred to allow pension administrators to adapt.
What you should do before April 2027
- Review your pension nomination forms (expression of wishes) to ensure they reflect your current wishes
- Consider whether you want to drawdown pension funds before 2027 to use them rather than have them taxed
- If your total estate including pension pots exceeds £500,000 (single) or £1,000,000 (couple), consult a financial adviser about options
- Update your will to coordinate with your pension planning — who inherits what in which order matters now more than ever
Understanding the residence nil-rate band (RNRB)
The RNRB is an additional £175,000 tax-free allowance but it has important conditions:
- You must leave a qualifying residential property to direct descendants (children, stepchildren, adopted children, grandchildren)
- The property must have been your main residence at some point
- The RNRB tapers away at £1 for every £2 if your estate exceeds £2,000,000
- If you downsize or sell your home, a downsizing addition may preserve the allowance
Crucially, the RNRB is lost if you leave your home to, say, a cohabiting partner who is not your civil partner, or if you leave it to a trust rather than directly to descendants. Your will must be structured correctly to claim it.
Spousal exemption: still fully available
All transfers between married spouses and civil partners remain fully exempt from IHT, with no upper limit. The unused NRB and RNRB also transfer to the surviving spouse. This makes a coordinated will strategy for couples critically important — ensuring the surviving spouse's will is structured to claim both sets of allowances on the second death.
How a will helps with IHT planning
Your will is the primary tool for IHT planning. Without one, the intestacy rules determine who inherits — and they are not designed for tax efficiency. A well-drafted will can:
- Ensure the spousal exemption applies on first death
- Claim both nil-rate bands on second death
- Include charitable legacies to reduce the IHT rate to 36%
- Leave the qualifying property to direct descendants to claim the RNRB
- Coordinate with pension nomination forms to minimise the combined IHT burden from April 2027
