5 Legal Ways to Reduce Inheritance Tax in the UK — And the Mistake That Undoes Them All
Most people assume inheritance tax is something that simply happens to their family after they've gone. A bill arrives, the estate pays it, and that's that.
It isn't quite like that. There are things you can do, they're entirely legal, and most of them are allowances Parliament has already written into the rules and expects you to use.
The difficulty isn't that they're hidden. It's that they're scattered. You hear about the seven-year rule in one place, an allowance for your home in another, something about gifts at Christmas somewhere else — and nobody ever puts them side by side so you can see how they fit together.
So that's what this article does. Five ways to reduce inheritance tax, in one place, followed by the mistake that quietly cancels out all of them.
First, let's clear something up
There's a widespread assumption that reducing inheritance tax means something clever. Something offshore. Something a bit murky and not quite above board.
It doesn't.
Nearly all of it is allowances that already exist and rules that are already written down. There are more advanced arrangements available, and for some families they're genuinely the right answer — but that's a conversation for after someone has properly looked at your circumstances. The five below come first. They apply to almost everybody, and if they're not right, nothing built on top of them works either.
The work isn't finding a loophole. It's using what's already there, deliberately, and in the right order.
1. Start with the allowances you already have
Every person has a nil rate band of £325,000. That's the amount that passes free of inheritance tax before anything is charged at all.
On top of that, if you leave your home to your children or grandchildren, there's a further allowance of up to £175,000 — the residence nil rate band, or what most people call the home allowance.
Two separate allowances, each with its own conditions.
The important point about the second one is that it is not automatic. It depends on your home passing to direct descendants, and that depends on how your Will is actually written. A Will drafted before April 2017 was written before this allowance existed — the person drafting it wasn't ignoring it, they simply couldn't have known it was coming. We see older Wills that unintentionally put it at risk.
Both allowances are frozen until April 2031. House prices, meanwhile, are doing what house prices do. That freeze is quietly pulling more ordinary families into inheritance tax every year, which is why this is the first place we look.
2. Give it away and live seven years
Give something to a child or a grandchild, survive another seven years, and it generally falls out of your estate altogether. No inheritance tax on it at all.
This is what people mean by the seven-year rule, and it's the best known of the five.
What's less well known is what happens if you don't survive the seven years. The gift can be pulled back into the calculation — and the tax on it lands on the person who received it, not on the estate generally.
That catches families out more than anything else we see. Someone receives a generous gift, spends it or puts it into a house, and years later finds there's a tax bill attached to it that nobody warned them about. The gift was real; the liability travelled with it.
It doesn't make gifting wrong. It makes it something to do with your eyes open, and ideally something the recipient knows about too.
3. Give from your income rather than your capital
This is the one most people have never heard of, and it may well be the most useful of the lot.
If you have more income coming in than you actually spend, you can give the surplus away — regularly, out of income rather than out of savings — without reducing your own standard of living. Done properly, those gifts are exempt immediately.
No seven-year wait. No upper limit.
For someone with a good pension and a paid-off house, that can be significantly more powerful than one-off gifts of capital.
The catch is evidence. HMRC will want to see that the gifts were regular, that they genuinely came from income, and that you weren't eating into your own capital to make them. And it isn't you who has to demonstrate that — it's your executors, after you've gone, going through years of bank statements trying to reconstruct a pattern.
Keeping a simple record of what you gave, when, and out of what income turns a difficult conversation with HMRC into a straightforward one. It costs nothing to do and it's very hard to reconstruct later.
4. Use the everyday exemptions
These are the small ones, and they're routinely dismissed as trivial:
£3,000 a year, which you can give away in total each tax year
£250 to as many different people as you like
Wedding gifts, within set limits depending on your relationship to the couple
Anything at all between spouses or civil partners
None of these is dramatic on its own. All of them are free. And used consistently over fifteen or twenty years, they move a sum that surprises people — without a seven-year clock, without paperwork, and without anybody needing to do anything clever.
The reason they get overlooked is that they don't feel like planning. They feel like birthdays and Christmas. But that's exactly what makes them easy to keep up.
5. Leave something to charity
Anything you leave to a UK charity is free of inheritance tax.
There's also a second part to it. If you leave at least a tenth of your taxable estate to charity, the rate charged on everything else drops from 40% to 36%.
So if leaving something to charity is already on your mind, the rules reward doing it properly rather than doing it casually.
Exactly how the numbers fall for your family depends on the size of the estate and what you were already planning to give, and it deserves a fuller treatment than we can give it here — it's a topic we'll come back to on its own. But that's the shape of it, and it's worth knowing the reduced rate exists before you write the figure into your Will.
The mistake that undoes all of it
Here's the one that catches people.
If you give something away but carry on enjoying it, it doesn't count as having been given away.
The classic example is signing the house over to the children while continuing to live in it rent-free. It feels like the asset has moved. The deeds say it has. But as far as HMRC is concerned, you never really gave it away — it's a gift with reservation of benefit, and it sits in your estate and is taxed in your estate exactly as before.
Years of good intentions, and no effect whatsoever.
Worse, the arrangement may have created other problems along the way — the property is now exposed to the children's divorces, bankruptcies and creditors, and there may be capital gains consequences nobody mentioned at the time.
This is the single most common well-meant mistake in this area, and it's almost always made by people who were trying to do the right thing for their family.
Why they only work together
Read those five back and you'll notice something. They don't sit in separate boxes.
Give from capital when you could have given from surplus income, and you've started a seven-year clock you never needed to start.
Use the everyday exemptions quietly for two decades and you've moved a serious sum with no clock at all.
And a Will written fifteen years ago can cost you the home allowance described in the first section, without anyone ever noticing, simply because it was drafted before that allowance existed.
Which is why the answer to "what should I do about inheritance tax" is almost never one of these five in isolation. It's a question of which of them apply to you, in what order, and whether everything you already have in place still points in the same direction as everything else.
Your Will, your gifting, your property, your pension and your wider assets were probably each dealt with by a different person at a different time. Individually, all correct. Together, not necessarily pointing the same way.
Someone has to hold the whole picture. That's the job.
