Navigating the 2027 UK Pension and Inheritance Tax Overhaul

For many years, UK pensions have fulfilled a dual role. Primarily, they are the foundational vehicle for building retirement savings. Quietly, however, they also became one of the most efficient tools for inheritance planning. A significant government reform, effective from April 2027, is set to fundamentally change this second role.

This article explores the upcoming April 2027 changes to the UK pension and inheritance tax framework and what they mean in practice for individuals, families, and executors. It outlines how pensions have historically been used in estate planning, explains the key elements of the reform, and highlights the financial and administrative implications that may arise.

1. The Previous Strategy: How Pensions Became a Cornerstone of Estate Planning

To grasp the full impact of the upcoming changes, it is essential to understand the historical context. For years, the specific tax treatment of defined contribution (DC) pensions created a significant estate planning advantage that became the cornerstone of sophisticated financial advice for a generation of savers.

A defined contribution pension is a type of pension where you and/or your employer pay money into a pension pot. That money is invested, so the value can go up or down over time. When you retire, what you get depends on how much has been paid in and how well the investments have performed, so the final amount is not guaranteed.

The idea of defined contribution was straightforward but effective. Because most defined contribution pension death benefits are paid out at the trustees’ discretion, the money is not treated as belonging to the person who died at the time of death. This means it usually does not form part of their estate for inheritance tax purposes, so it can be paid to beneficiaries without a 40% IHT charge.

This favourable tax treatment gave rise to what became the optimal strategy for maximising intergenerational wealth: "spend other assets first." This approach, brilliant in its simplicity, advised individuals to fund their retirement lifestyle using ISAs, cash, and other investments, preserving the pension pot to be passed on intact.

2. The April 2027 Reform: What Is Changing and Who Is Responsible

This upcoming legislative change is not a minor administrative tweak; it is a fundamental shift in how pension assets are treated upon death, with significant implications for tax liability, administration, and family finances.

The core of the reform is straightforward: from 6 April 2027, the government intends for most unused pension funds and pension death benefits to be included in the value of a person’s estate for IHT purposes. Crucially, the legislation is designed to override the very mechanism that made pensions so IHT-efficient in the first place: trustee discretion.

From 2027, even discretionary payments will be brought into the estate's value.

Which Pensions & Benefits will be Taxed Under the New Rules?

Currently, many pensions are outside the IHT net. From April 2027, they will be included.

The change will mainly affect:

• Defined contribution (money purchase) pensions: such as personal pensions or workplace schemes where funds build up in an individual pot.
• Discretionary pension death benefits: where trustees or scheme managers decide who receives the money.
• Non-discretionary schemes: these are already taxable but will now be subject to the same reporting and payment rules as discretionary schemes.
• Defined benefit, defined contribution, UK registered schemes, and QNUPs (Qualifying Non-UK Pension Scheme): unused funds or death benefits will be included.

This treatment will apply equally to discretionary and non-discretionary schemes.

How Does UK Inheritance Tax Apply to Overseas Pensions?

Where your pension is held can affect how it is treated for Inheritance Tax. From 6 April 2027, if you are a long-term UK resident, pension wealth in registered pension schemes, QNUPS and section 615(3) schemes can potentially fall within UK Inheritance Tax, even where the pension is held overseas. If you are not a long-term UK resident, overseas pension schemes will generally remain outside the UK IHT net.

There is also a practical difference in how any tax is collected. Withholding and payment notices cannot be used for QNUPS or section 615(3) schemes. In simple terms, these schemes cannot be required to hold back pension benefits or pay the IHT directly to HMRC under these rules.

Which Pensions & Benefits Will Remain Exempt?

Some pensions and benefits will continue to fall outside IHT:

• Death in service benefits payable from both discretionary and non-discretionary registered pensions schemes: lump sums paid when someone dies while still employed will stay tax-free.
• Certain defined-benefit dependants’ pensions: regular payments to a surviving spouse or dependent from a defined-benefit scheme will not be included.
• Transfers to a spouse or charity: even after 2027, if the pension is left to a spouse, civil partner, or charity, it remains exempt from IHT.

Also, many estates that remain under the IHT nil rate band will pay no tax even after this change.

Critically, following a public consultation, the government has decided that the responsibility for managing this new liability will not fall on pension companies. Instead, Personal Representatives (PRs) - the executors or administrators of an estate - will be legally liable for reporting the value of the pension funds to HMRC and paying any IHT that becomes due.

It is important to note one key exclusion: death in service benefits that are payable from a registered pension scheme are intended to remain outside the scope of these new rules. The financial implications of this change can be substantial, as the following worked example demonstrates.

The Ripple Effect: How the Reform Will Impact Families and Executors

The true impact of the 2027 reform extends far beyond the tax calculation itself. It creates new pressures on estate administration, cashflow, and family dynamics that require careful consideration and planning.

The Six-Month Deadline and Cashflow Pressure

Under existing rules, IHT is generally payable by the end of the sixth month after a person's death, with interest charged on late payments. By bringing large pension pots into the IHT net, more estates will face a substantial tax bill. This creates a "cash first, paperwork later" problem, especially for estates that are asset-rich but cash-poor.

For instance, where the main assets are a family home or illiquid investments within a SIPP, such as commercial property, executors may be forced into quick sales at "fire-sale pricing" to meet the deadline.

The Increased Burden on Personal Representatives

This reform places a heavy new administrative load on PRs. They must now identify all pension schemes, obtain valuations promptly, and correctly calculate the IHT due. The risk of "unknown pensions"- older, forgotten workplace schemes - is now a direct liability risk. To be discharged from future liability for any pensions discovered later, PRs must prove to HMRC's satisfaction that they made "every effort" to locate all schemes. This "every effort" standard elevates the role of executor from a family duty to a position of significant legal responsibility.

How Is Inheritance Tax Paid From a Pension?

For deaths on or after 6 April 2027, there are two main ways to help make sure any Inheritance Tax linked to a pension is paid before all the pension money is released.

Potential for Beneficiary Disputes and Delays

Conflict can arise from a “beneficiary mismatch”, where pension death benefits are nominated to one person, such as a child, while the residue of the estate passes to others. As personal representatives are responsible for settling the full inheritance tax liability from the estate, they may need to seek recovery of the tax attributable to the pension benefits from the pension beneficiary, which can be a source of family friction. This risk is heightened where the will is drafted so that one beneficiary’s entitlement is effectively received free of tax, leaving the economic burden of the inheritance tax to fall on other beneficiaries unless appropriate tax apportionment provisions are included.

Furthermore, the government's support mechanism for PRs carries its own issues. Under this system, a pension beneficiary may only be able to access up to 50% of the benefits for up to 15 months after death, creating a clear and potentially significant cashflow problem for family members.

The Double-Taxation Trap

A critical and often overlooked consequence is the risk of double taxation. A pension beneficiary may have to withdraw funds from their inherited pension simply to reimburse the estate for the IHT paid. That withdrawal could itself be subject to income tax at the beneficiary's marginal rate. This creates a painful scenario where tax is paid twice on the same funds - once for IHT on the estate, and again for income tax on the beneficiary.

The rules are designed to prevent the same pension money being taxed twice. If Inheritance Tax is paid on a pension death benefit, the amount used to meet that tax can be deducted before Income Tax is worked out.

If the pension scheme pays the IHT under a payment notice, Income Tax applies only to the remaining benefit. If the beneficiary pays the IHT themselves, they may instead be able to reduce their taxable pension income by the amount of tax they have borne.

So, in the example above, the £80,000 used to pay IHT should not simply be taxed again as pension income with no relief.

These practical challenges underscore the importance of proactive planning to mitigate stress and uncertainty for loved ones.

Proactive Planning: What to Consider Before April 2027

While the reform is significant, it does not negate the immense value of pensions. Instead, it calls for a more integrated and thoughtful approach to financial planning that balances multiple priorities.

Our first principle is unwavering: your retirement security comes first.

There is a clear risk in drawing down a pension solely to reduce a future IHT exposure, as this could jeopardise the funds you need to live on comfortably. Any withdrawal strategy must be carefully modelled to ensure it supports your long-term needs.

Building Your Executor's Defence

Good record-keeping has been elevated from a good habit to an essential defensive measure for your estate. We must work together to create a "pensions inventory"—a simple document listing all provider names, policy numbers, and contact details. This simple step can save your executors months of administrative work and, crucially, provides them with the evidence needed to prove they made "every effort" to locate all your assets, protecting them from future liability.

Because pension benefits left to a spouse or civil partner can still qualify for the IHT exemption, while benefits passing to children or grandchildren may be brought into the estate from 6 April 2027, your pension nominations matter more than before.

It is worth checking each pension scheme now. Make sure the people you have nominated still match what you actually want to happen, rather than relying on a form you may have completed years ago.

Stress-Testing Your Estate's Cashflow

Next, you must plan for your estate's liquidity. Your PRs will need cash to pay the IHT bill within six months, often before probate is granted. If your estate is largely illiquid—tied up in property, business interests, or specialist SIPP assets—we need to consider how this tax liability will be funded. Planning now can prevent a forced sale of assets at an unfavourable price later.

Facilitating Clear Family Communication

Finally, we must facilitate clear family communication. In situations where there is a "beneficiary mismatch," discussing your plans in advance can be invaluable. Ensuring all family members understand who receives what and, crucially, how the IHT attributable to pension benefits will be funded or reimbursed can prevent misunderstandings and disputes down the line.

The core principles of pension saving remain strong, even as their role in inheritance evolves.

Conclusion: A New Era for Pension and Estate Strategy

The reform scheduled for April 2027 marks the end of the "pension as a default inheritance wrapper" era. Families and their advisers must adapt to a new reality where most pension funds will be considered part of the estate for Inheritance Tax, with the administrative burden falling squarely on the shoulders of executors.

However, this does not diminish the pension's primary role. Pensions remain one of the most effective tools for long-term saving, thanks to the powerful combination of tax relief on contributions and tax-deferred growth on investments. The right strategy no longer treats the pension as a silo for inheritance, but as the powerful core of an integrated plan that must now account for retirement needs, tax efficiency, and the practical realities of estate administration.
