How to Avoid Inheritance Tax Traps

How to Avoid Inheritance Tax Traps

A Lionbridge Wealth Insight

Inheritance Tax (IHT) planning is no longer just a concern for the affluent. Frozen thresholds, rising property values, and increasingly complex rules mean that more families than ever are being pulled into the IHT net—often unintentionally. At Lionbridge Wealth, we regularly see families caught out by traps that could have been avoided with the right planning.

This article highlights the most common inheritance tax pitfalls and, crucially, how to avoid them.

1. Know Your Allowances — and How You Can Lose Them

Nil‑Rate Band (NRB) & Residence Nil‑Rate Band (RNRB)

The standard nil‑rate band remains £325,000, frozen until 2030. The residence nil‑rate band adds up to £175,000 when a main residence is passed to direct descendants, allowing couples to potentially pass on £1 million tax‑free. [jpmorgan.com]

The Trap: Losing the RNRB

Many estates lose all or part of this valuable allowance because:

• The estate exceeds £2 million, triggering tapering

• The home isn't left to direct descendants

• Downsizing wasn’t planned with RNRB rules in mind

Losing the full £175,000 RNRB at 40% tax results in a £70,000 tax charge—and with compounding planning mistakes, families often face £78,000 or more in unnecessary tax. [accenture.com]

How to Avoid It

✅ Keep your estate below £2 million where possible✅ Ensure your home is passed to direct descendants✅ Review your will to confirm RNRB eligibility✅ Get advice before downsizing

2. Use Lifetime Gifting Wisely

Gifting is one of the most powerful IHT planning tools, but only if executed correctly.

Understanding the 7-Year Rule

Gifts are generally exempt if you survive seven years. Gifts made within that window are potentially taxable, and their impact can be dramatic.

A real‑world example shows a £200,000 gift made 5 years before death resulted in a £36,000 tax bill, even after taper relief. Without taper relief, the bill would have been £90,000. [vistage.com]

Avoid These Gifting Traps

✅ Don’t make “gifts with reservation”—e.g., gifting your home but living in it rent‑free

✅ Record all gifts with dates and amounts

✅ Use annual allowances (£3,000 per year, £250 small gifts, wedding gifts)

✅ Make large gifts early to start the clock sooner

3. The Residence Nil‑Rate Band “Cliff Edge”

If your estate exceeds £2 million, your RNRB is reduced by £1 for every £2 above the threshold. This tapering can wipe out the entire residence allowance. [accenture.com]

How to Avoid It

✅ Strategic gifting to bring the estate value under £2 million

✅ Charitable giving

✅ Restructuring ownership of assets

✅ Early downsizing with correct paperwork

4. New Rules on Business & Agricultural Relief (Effective April 2026)

From April 2026, reliefs on trading businesses and farmland will be capped at 100% for the first £1 million. Any value above £1 million will be taxed at 20%, rather than the standard 40%. [mckinsey.com]

How to Avoid This New Trap

✅ Begin succession planning earlier

✅ Consider lifetime gifting of business/farm assets

✅ Explore trust options for long‑term control

✅ Review business valuations regularly

This is particularly important for farming families and business owners, who may be land‑ or asset‑rich but cash‑poor.

5. Avoid the “Asset‑Rich, Cash‑Poor” Scenario

Families with valuable properties, farmland, or business assets frequently struggle to pay IHT because their wealth isn’t liquid.This problem is becoming more widespread due to frozen thresholds and rising asset values. [accenture.com]

Solutions

✅ Use life insurance written in trust to cover future IHT

✅ Maintain a sensible mix of liquid and illiquid assets

✅ Reassess ownership structures (e.g., tenants in common)

6. Understand the New Residence‑Based IHT Rules (2025 Reforms)

From April 2025, IHT is shifting from domicile‑based to residence‑based taxation.If you have been a UK resident for 10 of the previous 20 years, you become a Long‑Term Resident (LTR) and are liable for IHT on worldwide assets. [jpmorgan.com]

Even after leaving the UK, you're still in scope for IHT for 10 years—the “tail rule.” [jpmorgan.com]

How to Avoid This Trap

✅ Review global assets well before reaching LTR status

✅ Carefully plan emigration timing

✅ Seek specialist advice if you hold assets overseas

7. Keep Your Will Updated

Many IHT traps stem from outdated wills.Changes in family structure, property ownership, or tax rules can all impact your tax position.

Review Your Will If You Have:

• Downsized your home

• Married or divorced

• Acquired significant assets

• Moved abroad

• Setup new trusts or business structures

•
