IHT & Wealth Structuring

How to Reduce Inheritance Tax: 10 Legitimate Strategies

Practical, legitimate strategies to reduce or eliminate inheritance tax liability for UK estates.

Quick Answer

The 10 most effective IHT reduction strategies are: (1) use the nil-rate band and residence nil-rate band fully, (2) make lifetime gifts (7-year rule), (3) claim Business Property Relief and Agricultural Property Relief, (4) write life insurance in trust, (5) use trusts for family wealth, (6) gift out of normal income, (7) use annual exemptions (£3,000), (8) leave 10%+ to charity (reduced 36% rate), (9) invest in AIM shares qualifying for BPR, and (10) restructure property ownership between spouses. The right combination depends on your estate composition.

Strategy 1-3: Allowances, Gifting and BPR

Every individual has a nil-rate band of £325,000 and a residence nil-rate band of £175,000 (when passing a home to descendants). Married couples can transfer unused allowances, potentially reaching £1M tax-free. Above this, the 40% rate applies.

Lifetime gifts are a core IHT strategy. Gifts made more than 7 years before death are completely free of IHT. Gifts within 7 years may be subject to taper relief. The annual exemption of £3,000, plus small gifts and wedding gifts, can be given each year without entering the 7-year calculation.

Business Property Relief (BPR) provides up to 100% relief on qualifying business assets, and Agricultural Property Relief (APR) does the same for qualifying agricultural property. These are the most powerful IHT reliefs for business owners and farmers — but the April 2026 changes restrict them above £1M.

Strategy 4-6: Life Insurance, Trusts and Income Gifting

Life insurance written in trust provides liquid funds to pay the IHT bill. Without it, the family may need to sell assets or take a loan. The policy must be written in trust — otherwise the payout adds to the estate and is itself subject to IHT.

Trusts allow you to pass wealth to beneficiaries while retaining some control. Discretionary trusts are flexible but have entry charges (20% above the nil-rate band) and 10-year anniversary charges. Bare trusts are simpler — the beneficiary gets the assets at 18.

Gifts out of normal income are exempt from IHT with no 7-year wait. To qualify, the gifts must be from income (not capital), must be regular (a pattern of giving), and must not reduce your standard of living. This is often overlooked but can be very powerful for retirees with pension income.

Strategy 7-10: Exemptions, Charity, AIM and Property

Key remaining strategies include:

  • Annual exemption: £3,000 per year (can carry forward 1 year if unused)
  • Small gifts: up to £250 per person per year, unlimited recipients
  • Wedding gifts: up to £5,000 (child), £2,500 (grandchild), £1,000 (others)
  • Leave 10%+ of the estate to charity: the IHT rate drops from 40% to 36% on the whole estate
  • AIM shares: 50% BPR after 2 years of holding (reduced from 100% from April 2026)
  • Property ownership restructuring: split property between spouses to use both nil-rate bands

Relevant Legislation

IHTA 1984 — full IHT framework. Nil-rate band: s.8. Residence nil-rate band: FA 2015 Sch.4. BPR: s.103-113. APR: s.115-123. Gifts out of income: s.21. Charitable bequests (36% rate): s.36. AIM/BPR from April 2026: Finance Bill 2025-26.

Practical Example

A married couple with a £2M estate (including a £1.5M home and £500K in investments) faced IHT of approximately £400,000. We implemented: (1) lifetime gifting of £200K in investments (7-year rule), (2) life insurance in trust (£400K cover), (3) annual exemptions of £6K/year for 5 years (£30K), (4) charitable bequest of 10% (reducing rate to 36%), (5) restructuring property ownership. Projected IHT reduced to under £80,000 — a saving of £320,000.

Common Mistake

Leaving IHT planning too late. The 7-year rule for lifetime gifts means planning should start as early as possible. Many people wait until retirement, but starting in your 50s or even 40s gives the maximum benefit from the 7-year rule and annual exemptions. Another mistake is not writing life insurance in trust — this alone can cost the estate 40% of the policy payout in unnecessary IHT.
