How to Reduce Your Inheritance Tax Bill UK: 12 Proven Strategies (2026)
There are 12 proven, legal ways to reduce inheritance tax in the UK. Some are immediate (normal expenditure from income, annual exemption, will update). Some take 2 years (AIM BPR shares). Some take 7 years (PETs to children). The best approach combines several — and starts now, because time is your most valuable asset.

12 Ways to Reduce Inheritance Tax: Complete Strategies
Make sure your will claims the RNRB — up to £175,000 extra threshold
The Residence Nil-Rate Band (RNRB — s8D IHTA 1984) adds £175,000 to the standard NRB (£325,000) — giving a single person an effective threshold of £500,000 and a couple up to £1,000,000. But it is only available where the main home passes to direct descendants (children, grandchildren). A will that leaves the home to a discretionary trust, a charity, or a non-descendant LOSES the RNRB — costing up to £70,000 per person in avoidable IHT. Update the will: leave the home outright to children, or to a surviving spouse via an IPDI trust with children as remaindermen. Cost: will update (one-off). IHT saving: up to £70,000 per person.
Use the annual exemption — £3,000 per year, immediately IHT-free
The annual exemption (s19 IHTA 1984) allows you to give away £3,000 per tax year completely free of IHT — with no 7-year clock and no conditions. Unused annual exemption from the previous tax year can be carried forward (but only one year's carry-forward is permitted). In year 1: up to £6,000 can be given IHT-free. On an estate of £700,000 with a £200,000 IHT bill: giving £3,000 per year for 20 years removes £60,000 from the estate, saving £24,000 in IHT (£60,000 × 40%). A couple can each use their annual exemption: £3,000 + £3,000 = £6,000 per year between them. Start now — every year without using the annual exemption is a year's exemption wasted.
Make PETs — gifts to children and grandchildren (IHT-free after 7 years)
Potentially Exempt Transfers (PETs — s3A IHTA 1984) are gifts to individuals: children, grandchildren, other individuals, and bare trusts. They are IHT-free if the donor survives 7 years from the date of the gift. Taper relief reduces the IHT to 32%/24%/16%/8% if death occurs in years 3–7. Make large gifts now: a £200,000 PET to your children made today (13 June 2026) becomes IHT-free on 13 June 2033. The same gift made in 3 years is not fully exempt until 2036. The 7-year clock starts the day you make the gift. Keep a record of all gifts for the IHT403 return. If the gift is a property or business asset, consider CGT implications (holdover relief may be available — s165 TCGA for business assets).
Invest in AIM BPR shares — 100% IHT-exempt after just 2 years
AIM-listed shares in qualifying trading companies qualify for Business Property Relief (BPR — s105(1)(bb) IHTA 1984) at 100% after 2 years of ownership. Unlike PETs, the assets remain in your estate (accessible during life) — the IHT exemption kicks in automatically at death after the 2-year qualifying period. From April 2026, the combined BPR/APR cap is £1,000,000 at 100%; above £1m the relief is 50% (effective 20% IHT rate). An AIM ISA combines income tax and CGT efficiency during life with IHT exemption on qualifying shares after 2 years. Use a specialist AIM BPR portfolio manager — not all AIM shares qualify. Invest as soon as possible; the 2-year clock starts from the date of investment.
Normal expenditure from income — uncapped, immediately IHT-free
Normal expenditure from income (s21 IHTA 1984) is the most underused IHT exemption. It applies where: (1) the gifts are made habitually (regularly — not one-off); (2) the gifts are made from income (not capital); (3) after making the gifts, you retain enough income to maintain your normal standard of living. There is no upper limit on this exemption — uncapped, immediately IHT-free, no 7-year clock. Practical application: if you have pension income, rental income, or investment dividends substantially exceeding your living costs, set up regular standing-order gifts to children or grandchildren. Keep records (bank statements, gift log, evidence of income and expenditure). The HMRC form IHT403 has a specific table for normal expenditure from income claims. The exemption is lost if it is not documented — good records are essential.
Leave 10%+ to charity — the 36% reduced IHT rate and estate reduction
Gifts to charity are IHT-exempt under s23 IHTA 1984 — the charitable amount is removed from the taxable estate. Additionally, if 10% or more of the net estate passes to charity, the 36% reduced IHT rate applies to the remaining chargeable estate (s36 IHTA 1984 / Finance Act 2012), compared with the standard 40% rate. Example: estate £700,000; NRB £325,000; taxable estate £375,000. Standard IHT: £375,000 × 40% = £150,000. With 10% to charity: charitable gift = £37,500 (10% of net estate); remaining taxable estate = £337,500; IHT at 36% = £121,500. IHT saving: £28,500 (vs the £150,000 without the charity). The family receives slightly less overall (£37,500 goes to charity), but the total IHT bill is meaningfully lower. For larger estates, the combined effect of the estate reduction AND the 36% rate can produce very efficient outcomes.
Whole-of-life insurance in trust — fund the IHT bill tax-efficiently
A whole-of-life assurance policy written in trust pays out on death to the trust beneficiaries outside the estate — providing funds to pay the IHT bill without the estate needing to sell assets. The life policy is NOT in the estate if correctly placed in trust (Married Women's Property Act 1882 s11 automatic trust for spouses; discretionary trust for others). The payout funds the IHT, preserving the assets for the beneficiaries. Premium payments: if premiums are paid from surplus income and meet the s21 IHTA 1984 conditions (regular, from income, retaining standard of living), the premiums themselves are IHT-exempt — normal expenditure from income. This is particularly valuable for larger estates where other planning is not fully effective, or where illiquid assets (a farm, a business) form most of the estate and could otherwise need to be sold to pay IHT.
Pension contributions before April 2027 — funds outside the IHT estate
Currently (until 5 April 2027): unused pension funds (SIPP, personal pension, drawdown) are outside the IHT estate. They pass to nominated beneficiaries free of IHT (though income tax applies on drawdown after age 75). From 6 April 2027 (Budget 2024), pensions enter the IHT estate. Action before April 2027: maximise pension contributions (up to £60,000/yr + carry-forward of unused allowances); review pension nominations; consider whether drawing down pension funds and gifting (via PETs or s21) is more IHT-efficient than leaving them to compound in the pension from 2027. For those with significant pension funds, this window (until April 2027) is the last opportunity to benefit from the current outside-the-estate treatment.
Equity release — the growing liability reduces the IHT estate
A lifetime mortgage (equity release) creates a debt secured on the home. The outstanding loan balance (including rolled-up interest) is deducted from the estate as a liability under s5 IHTA 1984. As the loan balance compounds over time, the net estate value falls — and the IHT bill falls with it. The equity released can be gifted to children as PETs (7-year clock) or given away using the annual exemption or normal expenditure from income. Combined effect: the mortgage liability reduces the estate; the gifted proceeds are also removed. IHT saving: the family receives the gifted amounts during the donor's life rather than after death, and the estate is reduced on both fronts. Caveat: the family receives less from the property sale (the mortgage is repaid first). Best suited for homeowners who want to gift proceeds to children now rather than through the estate on death.
Deed of variation — redirect an inherited estate within 2 years
If you receive an inheritance and your own estate is already above the IHT threshold, a deed of variation (s142 IHTA 1984) allows you to redirect all or part of the inheritance to other beneficiaries within 2 years of the deceased's date of death. The redirected gift is treated as if made directly by the deceased — it does not enter your estate and does not start a 7-year PET clock for you. If redirected to charity: IHT exempt, and the deceased's estate may qualify for the 36% reduced rate. If redirected to children/grandchildren: the gift passes from the deceased directly to them. This is the most powerful estate-planning tool available after a death — it can fundamentally restructure the IHT position of both the deceased's estate and the beneficiary's own estate.
Estate equalisation — balance assets between spouses to preserve RNRB
Where one spouse has a significantly larger estate than the other, and the larger estate exceeds £2,000,000 (triggering the RNRB taper), transferring assets between spouses reduces the larger estate and preserves more RNRB. Transfers between spouses are IHT-exempt (s18 IHTA 1984) and CGT-neutral (no gain/no loss — s58 TCGA 1992). By evening out the estates, both spouses can have estates below the £2m taper threshold, preserving full RNRB on both deaths. Saving per RNRB recovered: £70,000 (40% × £175,000). A couple with one estate of £2.8m and another of £200m could save up to £140,000 by equalising to approximately £1.5m each. Property transfer requires SDLT payment (even between spouses) and conveyancing — factor in transaction costs.
Spousal exemption — defer IHT to the second death, doubling the thresholds
Everything passing to a surviving spouse or civil partner under s18 IHTA 1984 is IHT-exempt on the first death — regardless of value. This defers all IHT to the second death. On the first death: (1) No IHT on assets passing to the surviving spouse; (2) 100% of the unused NRB is transferred to the survivor (s8A IHTA 1984); (3) 100% of the unused RNRB is transferred to the survivor (s8G IHTA 1984). On the second death: the survivor has the combined NRBs and RNRBs — up to £1,000,000 effective threshold. The will should be structured to pass everything to the surviving spouse on first death, ensuring 100% of both thresholds are transferred. The survivor's will then directs the home and assets to children to claim the full £1,000,000 combined threshold. Review regularly — if the surviving spouse later remarries, the IHT position changes.
Frequently Asked Questions
What is the most effective way to reduce inheritance tax?
The highest-impact strategies (roughly in order): (1) Will structure — claim the RNRB by leaving the home to children (saves up to £70,000 per person); (2) Lifetime PETs — gifts to children and grandchildren, IHT-free after 7 years; (3) AIM BPR portfolio — 100% IHT-exempt after 2 years; (4) Normal expenditure from income (s21 IHTA — uncapped, immediate, no 7-year clock); (5) Annual exemption (£3,000/yr — immediate). For larger estates: AIM shares, charitable legacy (36% rate), estate equalisation between spouses, and whole-of-life insurance in trust are additional high-value tools.
How much inheritance tax can I legally avoid in the UK?
With comprehensive planning, many estates can reduce or eliminate their IHT liability legally: A single person with a £500,000 estate (home + savings) may pay £0 IHT if the home passes to children (NRB £325,000 + RNRB £175,000 = £500,000 threshold). A married couple with a £1,000,000 estate can pay £0 IHT by using both partners' NRBs and RNRBs (combined £1,000,000 threshold). Larger estates can still substantially reduce IHT through a combination of AIM BPR shares, lifetime PETs, charitable legacies, and systematic annual gifting.
Can I give money to my children to avoid inheritance tax?
Yes — gifts to children are Potentially Exempt Transfers (PETs — s3A IHTA 1984). They are IHT-free if you survive 7 years from the date of the gift. There is no limit on how much you can give, but the 7-year survival requirement applies. The annual exemption (£3,000/yr) and normal expenditure from income (s21 IHTA — from surplus income) are immediately IHT-free with no 7-year condition. Gifts must be genuine — you must give up control with no reservation of benefit (s102 FA1986).
How does a charitable legacy reduce inheritance tax?
A charitable legacy (s23 IHTA 1984) removes the gifted amount from the taxable estate — immediately reducing the IHT bill at 40%. Additionally, if 10% or more of the net estate passes to charity, the IHT rate on the remaining taxable estate drops from 40% to 36% (s36 IHTA 1984 / Finance Act 2012). For an estate of £700,000 (above the £325,000 NRB), a 10% charitable legacy saves approximately £28,500 in IHT compared with no charitable giving.
What is the quickest way to reduce inheritance tax?
The quickest strategies (immediate effect, no 7-year wait): (1) Normal expenditure from income (s21 IHTA 1984) — regular gifts from surplus income are immediately exempt (uncapped); (2) Annual exemption (£3,000/yr) — immediately IHT-free; (3) AIM BPR portfolio — the 2-year clock is faster than the 7-year PET clock; after 2 years, the shares are 100% IHT-exempt; (4) Will update to claim RNRB — immediately saves up to £70,000 in future IHT. The 7-year PET route is not 'quick' but for younger or healthy donors is the most powerful route for large estate reductions.
Start With the Most Powerful Tool: Your Will
Every other strategy works better when backed by a well-drafted will. The RNRB alone saves up to £70,000 per person — but only if the will directs the home correctly. WillSafe will kits for England and Wales make it easy to structure your will for maximum IHT efficiency.
