Inheritance tax used to be a problem for rich people. Old money, country estates, that sort of thing. If you grew up in a semi-detached in the Midlands, you probably assumed it had nothing to do with you.
That assumption hasn’t held up well. The nil rate band, which is the threshold above which HMRC starts charging 40%, has been frozen at £325,000 since 2009. It won’t move until at least 2030. Meanwhile, average UK house prices have risen from around £165,000 in 2009 to over £285,000 today. In London and the South East, the numbers are considerably higher. Families who bought ordinary homes in ordinary streets are now sitting on estates that cross the IHT threshold, often without realising it. The demand for tax planning has grown accordingly, and not just from the traditionally wealthy. The tax hasn’t changed much. The asset values have.
The frozen threshold problem
When a tax threshold is frozen while asset values rise, it’s effectively a stealth tax increase.
In 2009, the average UK house was worth roughly half the nil rate band. Today, in many parts of the country, the house alone can exceed it. Add savings, pension assets (depending on their structure), investments, and any other property, and a family that considers itself solidly middle-class can easily find their estate in the £600,000 to £900,000 range.
The 2030 freeze means this trend continues. Every year of price growth pulls more estates over the threshold. Every year that passes without planning is a year of missed options.
Who this is actually hitting
The stereotype of the IHT-liable estate is someone with old inherited wealth, multiple properties, and a portfolio of investments. The reality is increasingly different.
Teachers, NHS workers, small business owners, tradespeople who bought property in the 1990s and watched its value multiply over 30 years. These are the families turning up at solicitors’ offices after a parent dies, discovering that the house they grew up in has created a six-figure tax liability.
It’s not that they made mistakes. It’s that the tax system moved around them while they were busy living their lives.
The residence nil rate band: helpful, but not automatic
There is some relief available. The residence nil rate band (RNRB) gives an additional £175,000 allowance when a property is left to a direct descendant. For a married couple, the combined allowances can reach £1,000,000 in the right circumstances.
But “in the right circumstances” is doing a lot of work in that sentence.
The RNRB tapers off if the total estate exceeds £2,000,000. It doesn’t apply to all property transfers. It requires the right will structure to work correctly. And it phases out entirely for estates above a certain size.
A lot of families assume they’ll benefit from it automatically. When the estate is administered, they sometimes find out they don’t.
What the planning window looks like
The options available to a family depend heavily on how early they act.
Acting 7 or more years before death opens up potentially exempt transfers (PETs): gifts that fall outside the taxable estate if the donor survives seven years after making them. This is one of the most effective tools available, and it costs nothing to use. It just requires time.
Acting 2-5 years before death still allows for some PET planning, trust structures, and insurance-based solutions to cover the expected tax bill. The options are narrower but still meaningful.
Acting after someone has died leaves almost nothing on the table. At that point, the family is mostly managing how to pay a bill that’s already been set.
Why people still don’t act
Part of it is procrastination. Death is uncomfortable to think about, and IHT planning requires thinking about it directly.
Part of it is a lack of information. People know the 40% headline rate but don’t know what their actual liability looks like, or what the realistic planning options are.
And part of it is a perception issue: that this kind of advice is expensive, complicated, or only worth pursuing for much larger estates. In practice, a professional assessment can clarify very quickly whether planning is worth it. For many families, the answer is obviously yes.
The middle-class IHT problem is real. The window to do something about it is open right now. Whether it stays open depends on when families choose to look at their situation seriously.
