Here's the practical view on the changes to Inheritance Tax in 2026, and why 'frozen' can still mean 'costly'. It covers the sticking points around thresholds, new relief limits for businesses and farms, and why AIM and pensions may need a rethink ...

Changes to Inheritance Tax, Challenge legacy's grasp, Families may shift

Most families will not feel the changes to Inheritance Tax in 2026 as a sudden shock; it will be more like noticing the tide has come in only after the sand has disappeared. The headline rate may look familiar, but the rules around what gets sheltered, and what slowly drifts into charge, are exactly where real-life costs tend to appear.

The quiet issue is that the Inheritance Tax threshold
is not rising with everything else!

When the nil rate band in 2026 remains at £325,000, and the residence allowance remains at £175,000, the maths is simple: more estates are nudged over the line even when people do not think of themselves as wealthy. This is the kind of predictable policy outcome that is easy to overlook until HMRC is asking for figures and deadlines.

For couples, the combined allowances can still be substantial when everything lines up, especially if assets pass to a spouse first and the available bands transfer. Yet what looks generous on paper can be squeezed by ordinary house price growth, especially in areas where even an average family home now consumes most of the tax-free space by itself. Seen through that lens, the changes to Inheritance Tax in 2026 are as much about what stays fixed as what is being rewritten.

Business owners and farming families are the group
most likely to notice a more visible shift!

Reliefs for qualifying trading and agricultural assets are being reshaped so that there is a clear allowance where 100% relief applies, followed by a reduced level of relief above it. The practical implication is that a family business can still be protected to a high level, but the plan needs to be measured against the new allowance rather than assumed to be fully covered indefinitely.

This is where estate planning stops being an abstract exercise and becomes a set of numbers that must be stress-tested.

The transferable nature of these relief allowances between spouses matters because it changes the optimal sequencing of who owns what and when. A structure that was 'good enough' under older assumptions might now waste relief, or concentrate value in one estate without meaning to. In other words, reduced Inheritance Tax rewards coordination, not just ownership.

Investors who have used AIM portfolios for inheritance mitigation should also pause. Relief that once removed, the value from charge can become only a partial shield under the tightened rules, which means the risk profile is no longer just about market volatility; it is about whether the expected tax saving still compensates for the investment characteristics. It is a strategic decision, not a box-ticking exercise, and it deserves to be revisited with current assumptions rather than legacy comfort.

Pensions sit slightly further down the timeline, but they
should still influence 2026 decisions!

If unused pension wealth is brought into the inheritance calculation from 2027, many families will want to rethink which assets are spent first, which are preserved, and how beneficiary nominations align with the broader estate.

The unpleasant scenario to plan around is a family facing both inheritance charges and later income tax on what is received, which is exactly the sort of double-friction outcome that good estate planning tries to prevent.

The practical takeaway is that the rules are becoming more technical at the edges, even if the headline rate is unchanged. Wills written years ago may still be valid, but 'valid' is not the same as 'efficient', and what HMRC will accept as qualifying or transferable can depend on details that are easy to miss when assets, ownership, and intentions have evolved.

A sensible next step is not panic, but a review that treats the estate as a system: property value, business interests, investment wrappers, pension intentions, and the order of gifting or transfers. Done properly, it turns the changes to Inheritance Tax in 2026 from a vague worry into a set of manageable decisions.

And those can be made on purpose rather than by default.

Until next time ...
