Inheritance Tax Planning UK 2026: 12 Legal Ways to Reduce Your IHT Bill
Updated 15 May 2026 · 9 min read · England & Wales
Inheritance tax (IHT) is charged at 40% on the value of your estate above the available nil-rate band — but the rules contain a wide range of exemptions, reliefs, and planning opportunities that can substantially reduce or eliminate the bill. This guide covers the 12 most effective legal strategies available in England and Wales in 2026.
The Starting Point: Know Your Exposure
Before planning, calculate your gross estate: property, savings, investments, life insurance not in trust, business interests, and gifts made in the past 7 years. Subtract debts and deduct available reliefs (nil-rate band £325,000 per person, residence nil-rate band £175,000 where applicable, plus any transferable amounts from a deceased spouse). IHT is 40% on whatever remains.
Many estates that appear exposed turn out to owe little or no IHT once all reliefs are correctly applied. The 12 strategies below reduce the taxable estate further.
12 IHT Planning Strategies
1. Use Both Nil-Rate Bands (NRB + RNRB)
Every individual has a nil-rate band of £325,000 (frozen until April 2030). Married couples and civil partners can transfer unused NRB to the survivor — potentially giving the survivor £650,000. Add the residence nil-rate band (£175,000 per person, transferable) and a couple can pass up to £1 million tax-free. The RNRB requires leaving a qualifying residential property to direct descendants (children, grandchildren, stepchildren who were treated as children).
Action: Ensure your will leaves the family home to direct descendants, directly or via a life interest trust. A discretionary trust that does not give direct descendants a right to the property can lose the RNRB.
2. Annual Gifting (£3,000 Per Year)
The annual exemption allows each person to give away £3,000 per tax year completely free of IHT — no 7-year survival required. Unused allowance carries forward one year only, so two years of unused allowance gives £6,000 in year one. A couple can give away £6,000 (or £12,000 if carried forward) each year with no IHT consequence. Over 10 years, a couple can remove £60,000+ from their estate through annual exemptions alone.
3. Normal Expenditure Out of Income (Unlimited)
Under s.21 IHTA 1984, regular gifts made from surplus income — after meeting normal living expenses — are immediately IHT-exempt regardless of size and survival period. This is one of the most powerful exemptions available to those with significant income relative to their outgoings (retirees with generous final-salary pensions, high earners, landlords with rental surplus).
Requirements: the gift must be (a) part of normal expenditure, (b) made from income not capital, and (c) leave the donor with enough income to maintain their usual standard of living. HMRC scrutinises these claims closely — keep detailed records on form IHT403.
4. The 7-Year Gifting Rule (PETs)
Any gift to an individual (a potentially exempt transfer, or PET) becomes fully IHT-exempt if the donor survives 7 years. Taper relief reduces the IHT rate if death occurs between 3 and 7 years after the gift:
| Years between gift and death | Effective IHT rate |
|---|---|
| 0–3 years | 40% |
| 3–4 years | 32% |
| 4–5 years | 24% |
| 5–6 years | 16% |
| 6–7 years | 8% |
| 7+ years | 0% (fully exempt) |
Note: taper relief reduces the IHT rate — it does not reduce the value of the gift. And taper relief only helps if the gift exceeds the available nil-rate band.
5. Write Life Insurance in Trust
A life insurance policy not written in trust falls into your estate on death and is subject to IHT at 40%. Writing the same policy in trust costs nothing extra and keeps the payout entirely outside the estate — it also pays out directly to beneficiaries without waiting for probate, typically within weeks.
For a £500,000 policy, writing in trust saves £200,000 in IHT (40%) and eliminates a 6–12 month probate delay. Contact your insurer to establish a bare or discretionary trust over the policy — most insurers provide standard forms at no charge.
6. Pension Planning (Act Before April 2027)
Until April 2027, unused defined-contribution pension pots sit entirely outside the IHT estate — the most straightforward IHT shelter available. Maximising pension contributions (subject to annual allowance and lifetime rules) reduces your estate while building a fund that passes IHT-free to nominated beneficiaries.
From April 2027, unused pots become part of the estate. The planning window is therefore finite. Steps to consider now: spend other assets before pension drawdown; use drawdown proceeds for gifting via annual exemptions; ensure nomination forms are current.
7. Charitable Giving — The 10% Rule
Gifts to qualifying charities in a will are fully IHT-exempt. If you leave at least 10% of the net estate (the estate after deducting the nil-rate band and other reliefs) to charity, the IHT rate on the remainder drops from 40% to 36%.
Worked example: net estate £500,000 above the nil-rate band. At 40%, IHT = £200,000. Leave £50,000 (10%) to charity, reducing the taxable estate to £450,000 at 36%: IHT = £162,000. Total to beneficiaries: £450,000 − £162,000 = £288,000 vs £300,000 without the gift — only £12,000 less, but £50,000 went to charity. Depending on the charity and family circumstances, this can be a compelling option.
8. Business Property Relief (BPR)
Business Property Relief gives 100% IHT relief on qualifying business assets: sole trader businesses, trading partnership interests, and unquoted (including AIM) trading company shares held for at least two years. A 50% relief applies to controlling quoted company shares and property used in a qualifying business.
From April 2026, BPR is capped at £1 million combined with Agricultural Property Relief. Estates with qualifying business or agricultural assets above £1 million pay IHT at an effective 20% on the excess. AIM share portfolios specifically structured for BPR (“BR-qualifying investments”) are available from investment managers — typically a 2-year holding period and higher management fees, but 100% IHT relief if qualifying.
9. Agricultural Property Relief (APR)
Qualifying agricultural land and farmhouses receive 100% or 50% IHT relief. The occupation/ownership tests require either 2 years of owner-occupation or 7 years of letting to a working farmer. APR shares the £1 million cap with BPR from April 2026. APR on a farmhouse requires the house to be of a character appropriate to the farm — large detached farmhouses with minimal farming activity are regularly challenged by HMRC.
10. Equity Release to Reduce Estate Value
A lifetime mortgage reduces the value of your estate by the outstanding loan amount — directly reducing the IHT bill on property. Gifting the released funds starts the 7-year clock on a PET. However, equity release also reduces the inheritance your beneficiaries receive; the interest roll-up means the loan grows significantly over time. This is a planning tool, not a silver bullet — model both the IHT saving and the net inheritance carefully before proceeding.
11. Trusts for IHT Planning
Placing assets into trust can remove them from your estate for IHT — but the rules are strict:
- You must not retain a benefit from the trust (gift with reservation rules)
- Discretionary trusts pay periodic charges (up to 6% every 10 years) and exit charges
- A nil-rate band discretionary trust in a will can shelter £325,000 per spouse
- Charitable trusts remove assets from IHT entirely
- A bare trust for a minor grandchild is a PET — 7-year survival required
Trust planning carries ongoing administrative obligations and costs. Take specialist advice before establishing a trust for IHT purposes.
12. Deed of Variation After Death
A deed of variation allows beneficiaries to redirect an inheritance within two years of death — and HMRC treats the variation as if the deceased made it. This means a beneficiary can redirect their inheritance to charity (gaining the 36% rate), to a grandchild (using the grandchild's nil-rate band), or into a trust — retrospectively improving the estate's IHT position. All residuary beneficiaries affected must consent and sign. A deed of variation cannot create new gifts that were not part of the original estate.
What Does Not Work
- Putting your home in trust while living in it — the gift with reservation rules treat the property as still in your estate for IHT (IHTA 1984 s.102)
- Deliberate deprivation of assets before care — local authorities can notionally add back assets transferred to avoid care fees (Care Act 2014)
- Deed of variation to manufacture gifts not in the will — HMRC only accepts DoVs that redirect what was actually left, not add new assets
- Artificial BPR schemes — HMRC actively challenges arrangements where investment assets are disguised as trading assets to claim BPR; penalties apply
Frequently Asked Questions
What is the most effective way to reduce an inheritance tax bill in the UK?
There is no single answer — the most effective strategy depends on estate size, composition, and family circumstances. For most people, a combination of (1) maximising pension contributions (currently outside the estate until April 2027), (2) annual gifting using the £3,000 exemption and normal expenditure out of income, (3) ensuring both spouses use their nil-rate band and residence nil-rate band, and (4) writing life insurance in trust are the highest-impact actions available without complex structures. For estates over £2 million, business property relief, agricultural property relief, and trust planning can produce much larger savings — but specialist advice is essential.
Can I give money away to avoid inheritance tax?
Yes — gifts are one of the main planning tools, but the rules are complex. Any gift to an individual (a potentially exempt transfer, or PET) becomes fully IHT-exempt if the donor survives 7 years. If the donor dies within 7 years, taper relief reduces the IHT rate from year 3 onwards (40% at 0–3 years, 32% at 3–4 years, down to 8% at 6–7 years). Each person also has a £3,000 annual exemption (carry forward one year), small gifts exemption of £250 per person, and wedding gift exemptions. Unlimited gifts can be made from surplus income under the normal expenditure exemption (s.21 IHTA 1984) — but must be regular, habitual, and leave the donor with enough to maintain their standard of living.
Does a trust reduce inheritance tax?
It depends on the trust type. Assets in a discretionary trust are subject to IHT periodic charges (every 10 years at up to 6%) and exit charges when distributed — but the assets are outside the settlor's estate for IHT purposes (if the settlor does not benefit). A life interest trust where the settlor retains a benefit is treated as part of the estate. A nil-rate band discretionary trust created in a will can shelter up to £325,000 from IHT on the first death. A charitable trust shelters assets from IHT entirely. Trust law is complex and carries ongoing administrative and tax obligations — always take specialist advice before using a trust for IHT planning.
What happens to pensions and inheritance tax from April 2027?
From April 2027, unused defined-contribution pension pots will be included in the estate for inheritance tax purposes — currently they are outside the estate and one of the most effective IHT shelters available. The planning window before April 2027 is therefore significant. Actions to consider now: spend down other estate assets before pension funds; maximise pension drawdown and gift the proceeds using annual and other exemptions; review nomination forms so pension trustees know your wishes; consider other IHT-efficient investments (AIM ISAs, BR-qualifying investments) to replace the IHT advantage previously held by the pension. The change does not affect death benefits from defined-benefit (final-salary) pensions in the same way — those pay lump sums or spouse's pensions that may continue to be outside the estate.
What is business property relief and who qualifies?
Business Property Relief (BPR) gives 100% IHT relief on qualifying business assets — sole trader businesses, interests in trading partnerships, and unquoted (including AIM-listed) trading company shares — provided the owner has held them for at least two years. A 50% relief applies to quoted controlling shareholdings and business property used by a company the owner controls. From April 2026, BPR is capped at £1 million combined with Agricultural Property Relief — excess qualifying assets are taxed at an effective rate of 20% rather than 0%. BPR does not apply to investment businesses (property rental companies, investment holding companies). A family home converted to a business asset specifically to obtain BPR will be challenged by HMRC.
Is it worth making a will specifically for inheritance tax planning?
Absolutely. A well-drafted will is the foundation of IHT planning. Without a will, the intestacy rules distribute your estate in a fixed order that may not maximise available IHT reliefs — for example, assets passing to siblings rather than a spouse miss the unlimited spouse exemption. Specific will provisions that affect IHT: (1) leaving at least 10% of the net estate to charity reduces the IHT rate from 40% to 36%; (2) a life interest trust for a surviving spouse preserves the residence nil-rate band on the second death; (3) a nil-rate band discretionary trust on the first death can shelter up to £325,000 in certain circumstances; (4) specific gifts to direct descendants ensure the RNRB is available. IHT planning through a will must be reviewed when thresholds change — including the April 2027 pension reforms.
