Understanding UK Inheritance Tax, What You Can Pass On and How to Plan Properly

Inheritance Tax (IHT) is one of the most misunderstood areas of UK financial planning.

In this blog I will cover these areas:

• What is the current IHT threshold?

• How much can I pass to my children tax-free?

• Is it different if I am married?

• Are pensions outside the estate?

• What happens if I live abroad long term?

• What planning solutions are available?

These are critical questions.

Without proper planning, up to 40% of your estate above the available thresholds can be lost to HMRC.

Let’s break this down clearly.

The Standard Inheritance Tax Threshold

The UK operates a nil-rate band (NRB).

This is the amount you can pass on before IHT is applied.

• Standard Nil-Rate Band: £325,000

• IHT rate above this threshold: 40%

If you are single and leave an estate worth £825,000:

• £325,000 is tax-free

• £500,000 is taxable

• IHT bill = £200,000

The tax is typically due before assets are fully distributed.

The Residence Nil-Rate Band (Family Home Allowance)

If you leave your main residence to direct descendants (children or grandchildren), you may also qualify for the Residence Nil-Rate Band (RNRB).

• Additional allowance: £175,000

• Available when passing the family home to lineal descendants

• Tapers away for estates above £2 million

For an individual, this can increase the tax-free allowance to:

£325,000 + £175,000 = £500,000

But it only applies if the home passes to qualifying beneficiaries.

What Married Couples and Civil Partners Can Pass On

Married couples benefit from a significant advantage:

Unused allowances transfer between spouses.

If the first spouse leaves everything to the surviving spouse:

• No IHT is due (spousal exemption)

• 100% of unused nil-rate bands transfer

This means on second death, a married couple can potentially pass:

• £325,000 × 2 = £650,000

• £175,000 × 2 = £350,000 (if residence qualifies)

Total possible tax-free estate: £1 million

Anything above this is taxed at 40%.

For many property-owning families, estates exceed this threshold quickly.

UK Pensions, No Longer Automatically “Outside” the Estate

Historically, UK pensions were viewed as highly efficient estate planning tools.

Pensions are increasingly discussed in government policy making decisions and if not structured correctly they may form a part of your estate.

This is something you should speak to a financial planner about, establishing the correct route for pensions can mitigate the risks of IHT.

Relying on pensions alone as an IHT solution is no longer sufficient planning.

Long-Term Residency and Domicile Risk

Inheritance Tax is not based purely on where you live.

It is primarily driven by domicile status.

You may be subject to UK IHT if you are:

• UK domiciled

• Deemed domiciled (replaced with long-term UK resident)

• Returning to the UK after extended time abroad

Long-term expatriates often assume they are outside UK IHT indefinitely.

That is not always the case.

Deemed rules can apply after extended UK residence, and UK assets such as property remain within scope regardless.

Cross-border families must plan carefully.

What Does This Mean in Practical Terms?

Without planning:

• A £1.5 million estate for a married couple could face a £200,000 IHT bill

• A £3 million estate could lose £800,000+

• Property inflation alone can push estates above thresholds

• Business, property and pension investors are especially exposed

IHT is often described as a “voluntary tax”, in the sense that proper planning can materially reduce exposure.

Strategic Planning Solutions

Effective IHT planning is not about avoidance.
It is about structuring efficiently and legally.

Common strategies include:

1. Life Insurance for IHT Liquidity

A whole-of-life policy written in trust can:

• Provide a tax-free lump sum

• Cover the projected IHT liability

• Prevent forced sale of property or business assets

This ensures beneficiaries receive assets intact.

2. Gifting Strategies

• Potentially Exempt Transfers (7-year rule)

• Annual exemptions

• Normal expenditure out of income

• Trust-based gifting

Timing and documentation are critical.

3. Offshore Tax Wrappers

For internationally mobile families, properly structured offshore investment bonds can:

• Provide tax deferral

• Allow assignment flexibility

• Improve estate segmentation

• Enable trust planning integration

Structure matters as much as asset selection.

4. Pension Coordination

Pensions can still form part of an estate strategy, but:

• Beneficiary nominations must be updated

• Intergenerational planning should be coordinated

• Drawdown vs preservation decisions must be analysed

• Other alternatives for international families can be made

5. Trust Structures

Appropriate use of trusts can:

• Remove assets from the taxable estate

• Provide control over distribution

• Protect beneficiaries

However, trusts must be structured carefully to avoid unintended tax charges.

The Bigger Picture

Inheritance Tax planning is not about tax alone.

It is about:

• Protecting family wealth

• Preserving property portfolios

• Avoiding forced sales

• Creating liquidity

• Maintaining intergenerational stability

As asset values rise and thresholds remain frozen, more families are being pulled into the IHT net each year.

Doing nothing is a decision — and often the most expensive one.

Final Perspective

A single individual may pass up to £500,000 tax-free (subject to conditions).
A married couple may pass up to £1 million tax-free.

Anything above that is taxed at 40%.

Property inflation, pensions, business assets, and investment growth can push estates above these thresholds faster than most realise.

Inheritance Tax planning requires:

• Clarity on domicile

• Accurate estate valuation

• Structured liquidity planning

• Integrated investment and estate coordination
