The New Inheritance Tax Rules and What They Mean for Your Estate
Big changes are coming to inheritance tax in the United Kingdom, and they could affect how much of a pension gets passed on to loved ones.
Starting 6 April 2027, unused pension funds will count as part of a deceased person’s estate for inheritance tax purposes.
Starting April 2027, unused pension funds will become part of a deceased person’s estate for inheritance tax purposes.
Think of it like the government finally noticing money tucked under the mattress.
The standard tax rate stays at 40% on anything above £325,000.
Spouses and charities remain exempt.
Most estates still will not owe anything extra, but those with large pension savings could face a noticeably bigger bill.
Death in service benefits paid from a registered pension scheme will remain outside the new rules.
If a home is left to children or grandchildren, the threshold rises to £500,000 before tax applies.
Be sure to account for all relevant expenses, including depreciation and other costs, when estimating the true impact on your estate.
Why Your Pension Becomes an Inheritance Tax Liability in 2027
For most of its life, a pension has been a kind of financial invisibility cloak. Hidden from Inheritance Tax, it passed quietly to loved ones. From April 2027, that cloak disappears.
Here is why pensions become taxable:
- Unused pension funds join the estate’s total value.
- No separate pension nil-rate band exists to protect them.
- Anything above the standard threshold faces 40% tax.
The pension’s gross value at death is what counts. Suddenly, a pot built for retirement becomes part of a tax calculation. That changes everything for careful planners. Most UK pension schemes are currently discretionary, meaning trustees hold the power to distribute unused funds outside the estate entirely.
IHT on notional pension property falls due at the end of the sixth month after the date of death, after which late payment interest begins to accrue.
This shift could significantly affect those who relied on pensions to provide a steady income in retirement.
How Farms and Family Businesses Face Higher Inheritance Tax From 2026
Pensions are not the only assets losing their tax shelter. From April 2026, farms and family businesses face a significant inheritance tax shake-up.
From April 2026, farms and family businesses join pensions in facing a significant inheritance tax shake-up.
Previously, qualifying assets could pass down generations almost entirely tax-free. A common risk management tool for investors is a stop-loss order which illustrates how preset rules can protect assets from sudden market moves.
That generous unlimited relief is ending.
Full 100% relief now applies only up to £2.5 million per person.
Value above that threshold receives just 50% relief, creating an effective 20% tax rate on the excess.
Couples can combine allowances up to £5 million.
From April 2027, most defined contribution pensions will be brought into the estate for inheritance tax purposes, potentially consuming the personal nil-rate band and exposing more non-agricultural assets to tax.
Farms with high land values but little cash face the toughest challenge, since selling fields to pay a tax bill is nobody’s ideal solution. In the United States, by contrast, recent legislation raised the estate tax exemption to £30 million for couples, offering far greater protection for family farming operations across generations.
The Inheritance Tax Allowance Gap Facing Single Parents and Unmarried Couples
The inheritance tax system treats married couples very differently from single parents and unmarried couples, and that gap can cost families a significant amount of money.
Single parents and unmarried couples face three key disadvantages:
- No unused allowance transfers to a partner after death
- The first death can trigger an immediate tax bill above £325,000
- Without a qualifying home left to children, the extra £175,000 relief disappears
Married couples can combine allowances up to £1,000,000 tax-free.
Single parents are stuck at £500,000 at best.
Same assets, very different bills.
The frozen thresholds keep this gap firmly in place. Inheritance Tax is charged at 40% on the portion of an estate above the £325,000 threshold. From 2027, pensions brought into scope will also count toward an estate’s value, widening the tax exposure for single parents who have relied on pension savings as a sheltered asset. Households should also maintain an emergency fund to help manage liquidity pressures if tax bills become due.
How Much More Widespread Will Inheritance Tax Become by 2033?
Inheritance tax is quietly catching up with more and more ordinary families, and the numbers tell a striking story.
By 2032–33, over 7% of all deaths could trigger an inheritance tax bill.
That might sound small but it represents a huge jump from today.
One in eight people will likely face this tax either on their own death or a partner’s.
Receipts are expected to double to around £15 billion annually.
Frozen thresholds are the main culprit.
As house prices and savings rise, more estates quietly drift past the £325,000 limit without anyone moving a single piece of furniture.
Upcoming reforms are set to accelerate this trend, with unused pension savings becoming part of a deceased’s estate for inheritance tax purposes from April 2027.
From April 2025, the rules have also shifted for long-term overseas residents, with UK tax residency for 10 of the previous 20 years now determining whether worldwide assets fall within the inheritance tax net.
These changes could make capital preservation strategies more important for families planning long-term.
