Inheritance Tax on Pensions from April 2027: Why Estate Planning Cannot Wait

For decades, pensions have been one of the most effective and tax-efficient tools available for passing wealth to future generations. Many individuals have deliberately preserved their pension funds throughout retirement, choosing instead to spend savings, investments, and other assets first. The rationale was simple: pension pots generally sat outside of an individual’s estate for Inheritance Tax (IHT) purposes.

However, a major change is on the horizon.

From 6 April 2027, unused pension funds and certain pension death benefits will generally be brought within the scope of Inheritance Tax. The reform represents one of the most significant changes to estate planning in recent years and could substantially increase the tax burden faced by many families.

Whilst the rules are not yet in force, HMRC has published a Technical Note outlining how the new regime is expected to operate, giving individuals and advisers a valuable opportunity to review their planning before the changes take effect.

 

What Is Changing?

Under the current system, most defined contribution pension funds fall outside the deceased’s estate for IHT purposes. This has allowed pension wealth to be passed to beneficiaries in a highly tax-efficient manner.

From 6 April 2027, the Government intends to include unused pension funds and certain pension death benefits when calculating the value of an estate for Inheritance Tax purposes.

As a result, pension savings that have previously escaped IHT may now be subject to the standard 40% inheritance tax charge where the overall estate exceeds available allowances.

For individuals who have spent years building substantial pension funds, this could create a significant and unexpected tax liability for their beneficiaries.

 

Why This Matters

Many retirees have intentionally adopted a strategy of preserving their pension funds while drawing income from ISAs, savings accounts, investment portfolios, or property assets.

The reasoning was straightforward:

• Pension funds remained invested tax-efficiently.
• Pension wealth could often be passed down outside the estate.
• Other assets were more exposed to Inheritance Tax.

From April 2027, this strategy may no longer be the most efficient approach.

Individuals with large pension pots could find that a significant portion of their retirement savings becomes exposed to inheritance tax for the first time.

 

Example

Consider an individual with:

• Family home worth £750,000
• Savings and investments of £300,000
• Pension fund worth £600,000

Total wealth: £1.65 million

Under current rules, the pension may sit outside the estate for IHT purposes.

After April 2027, the pension could be included, potentially exposing an additional £600,000 to inheritance tax.

At a 40% IHT rate, this could create an additional tax liability of up to £240,000 depending on available allowances and personal circumstances.

For many families, this could significantly reduce the amount ultimately inherited by children and grandchildren.

 

Who Is Most Likely to Be Affected?

Whilst the reforms could impact a wide range of taxpayers, those most likely to be affected include:

 

➡️ Individuals with Large Defined Contribution Pension Funds

Those who have accumulated substantial pension savings over many years may see the greatest impact, particularly where pensions form a significant part of their overall wealth.

 

➡️ Higher Net Worth Families

Families whose estates already exceed available inheritance tax allowances could face considerably larger IHT bills once pension funds are included.

 

➡️ Business Owners

Business owners are already reviewing their estate planning due to proposed reforms affecting Business Property Relief (BPR). The pension changes add another layer of complexity.

 

➡️ Farmers and Landowners

Agricultural families facing changes to Agricultural Property Relief (APR) may also be affected by the inclusion of pension wealth within their taxable estates.

 

➡️ Estate Planning Opportunities Before 2027

The good news is that there remains a planning window before the new rules take effect.

Those who may be affected should consider reviewing their arrangements sooner rather than later.

 

1. Review Your Retirement Income Strategy

Many retirees have intentionally avoided drawing from their pension.

With pensions becoming part of the taxable estate, it may become more sensible to:

• Withdraw pension funds gradually;
• Utilise pension income for living expenses;
• Preserve other tax-efficient assets where appropriate.

Every individual’s circumstances are different, but the traditional “leave the pension untouched” strategy may no longer be optimal. 

 

2. Review Beneficiary Nominations

Ensuring pension beneficiary nominations are current has always been important.

Now is an ideal time to review:

• Expression of wish forms;
• Named beneficiaries;
• Trust arrangements;
• Potential succession plans for future generations.

Outdated nominations can create unnecessary complications and delays for families.

 

3. Consider Lifetime Gifting

Making gifts during your lifetime may help reduce the value of your estate.

Options may include:

✔️ Utilising annual gifting allowances;

✔️ Making larger potentially exempt transfers (PETs);

✔️ Funding education costs for children or grandchildren;

✔️ Passing wealth to family members earlier.

Any gifting strategy should be carefully structured and documented.

  

4. Review Your Will

Many wills were drafted under the assumption that pension funds would remain outside the estate.

The upcoming changes make it sensible to review:

✔️ Existing wills;

✔️ Trust provisions;

✔️ Distribution instructions;

✔️ Estate liquidity planning.

A will review may identify opportunities to improve tax efficiency and ensure assets pass according to your wishes.

 

5. Explore Trust and Succession Planning Structures

Depending on personal circumstances, alternative estate planning structures may help mitigate future tax exposure.

Professional advice is essential, as the effectiveness of different structures will vary significantly between families.

 

6. Consider Whether Annuities Could Play a Role

Current Government proposals suggest that annuities may remain outside the scope of the new pension inheritance tax rules.

Whilst annuities are not suitable for everyone, they may become increasingly attractive for certain retirees seeking certainty and inheritance tax efficiency.

 

HMRC’s Implementation Timetable

The Government’s planned timetable currently includes:

➡️ Spring 2026

Draft regulations and technical consultation.

➡️ Summer 2026

Further regulations laid before Parliament.

➡️ Autumn 2026

Draft guidance published for industry stakeholders.

➡️ Spring 2027

Final guidance issued.

➡️ 6 April 2027

New pension inheritance tax rules take effect.

Whilst some technical details remain subject to consultation, the direction of travel is clear.

 

Common Mistakes to Avoid

As the deadline approaches, individuals should avoid several common planning mistakes:

 

Waiting Until 2027

Many planning opportunities require time to implement effectively. Delaying action could reduce available options.

 

Assuming Existing Strategies Still Work

Estate planning that was effective under previous rules may no longer deliver the same outcomes after April 2027.

 

Ignoring Pension Wealth During Estate Reviews

Historically, pensions were often considered separately from inheritance tax planning. Going forward, they must be viewed as part of the wider estate picture.

 

Failing to Update Documentation

Outdated wills, beneficiary nominations and trust arrangements can undermine otherwise effective planning.

 

Taking Action Without Professional Advice

Inheritance tax planning involves complex interactions between pensions, income tax, capital gains tax, trusts and estate law. Professional advice remains essential.

 

The Bottom Line

The inclusion of pension funds within the inheritance tax regime from April 2027 represents a fundamental shift in UK estate planning.

For years, pensions have been regarded as one of the most effective vehicles for passing wealth between generations. That advantage is set to diminish significantly.

Individuals with substantial pension savings should use the remaining planning window wisely. Reviewing retirement income strategies, updating estate planning documents, considering gifting opportunities and seeking professional advice now could help families avoid substantial tax liabilities in the future.

The changes may still be over a year away, but for those likely to be affected, planning cannot afford to wait.
