How to cut your Inheritance Tax bill in 2025

With new data showing the regions paying the most Inheritance Tax, we look at ways you can minimise your obligation.

The UK areas paying the biggest Inheritance Tax bills

New data has revealed the parts of the country facing the steepest Inheritance Tax (IHT) charges – and unsurprisingly, London dominates the list.

According to HMRC data, Kensington tops the table, with estates that paid IHT facing an average bill of £1.38 million in 2022/23.

Chelsea and Fulham came second (£1.11m), followed by the Cities of London and Westminster (£1.08m).

However, two areas outside London stand out: Torridge and West Devon, where the average bill was £534,247.

The figures, analysed by law firm Irwin Mitchell, highlight how rising property values and investment portfolios are pushing more families into the IHT net.

The firm also forecasts that by 2028, the share of estates paying IHT will rise from 4% to 7%, with Greater London’s annual bill jumping 54% to £2.6 billion.

A shock Government move

And it seems these pressures are only going to get worse.

In one of its most controversial moves since coming to power, the Government has dragged private pension pots into the scope of IHT.

Experts warn this could turn estate planning into a “legal and emotional minefield”, particularly if executors are forced to sell assets to cover tax bills.

And with allowances frozen until 2030, more families than ever will need to consider careful estate planning to reduce the risk of a hefty tax shock

But first, remember that Inheritance Tax is just one of many taxes out there. If you're looking for a complete guide to cutting down your Income Tax, Council Tax and Capital Gains Tax bills, click here.

Tax relief: the nil-rate bands that matter

There are effectively two tax allowances you need to know about. 

First is the general nil-rate band, which covers anything up to £325,000.

Although this had previously been frozen until at least April 2028, Chancellor Rachel Reeves has extended the window until 2030.

The second allowance, known as the main residence nil-rate band, was introduced in April 2017.

It only applies when a main residence is passed to children or grandchildren after death and sits at £175,000. 

This band is on top of the existing Inheritance Tax threshold, so it creates an effective limit of £500,000 for individuals and £1 million for couples.

What if I downsize?

The main residence nil-rate band still applies if someone downsizes or ceases to own a home.

For example, let’s say you choose to downsize from a home worth £200,000 to one worth £100,000.  

According to the Treasury, you can still benefit from the maximum allowance of £175,000 if you leave the home and £75,000 of other assets to direct descendants.

Unfortunately, many plan to leave their home to other family members like nieces, nephews, aunts or cousins, ruling themselves out.

The most expensive homes

What's more, there will be tapered withdrawal of the main residence nil-rate band for estates with a net value of more than £2 million.

This withdrawal will be at a rate of £1 for every £2 the estate is valued over the £2 million threshold.

So, for example, if your estate is valued at £2.1 million, it would lose £50,000 of the allowance.

Use a charity discount if you want to help others

There's a reduced rate of Inheritance Tax of 36% for those who leave 10% or more of the net value of their estate to charity.

Your loved ones won’t be any better off if you go down this route – you’ll just ensure that some of your bill goes towards a cause you care about, rather than to the Treasury! 

HMRC has even provided a calculator to work out how much you could save: click here.

Gifts can help you shift small sums tax-free

We all hav\e a £3,000 limit each year for gifts, which is completely free of Inheritance Tax.

What’s more, if you don’t use your allocation this year, it can be carried over to next year, so you can hand over £6,000 to a loved one, tax-free!

You can also give away £250 each to a number of people every year, though you can’t combine it with the £3,000 annual allowance. They are different exemptions.

Weddings also offer an opportunity to avoid Inheritance Tax. Parents can give their children £5,000 each as wedding gifts, £2,500 to grandchildren or great-grandchildren, or wedding gifts of £1,000 to anyone else.

There are hoops to jump through though. The gift must be made (or at least promised) on or shortly before the day of the wedding.

You can leave cash to a political party free of tax too. However, not all parties qualify – they will need to have at least two members elected to the House of Commons, or one member where the party received at least 150,000 votes.

Finally, regular gifts that come out of your income (say a monthly payment to a family member) are also exempt so long as they do not affect your standard of living.

Potentially exempt transfers (PET) are key. Just don't die!

You can actually make additional gifts, above and beyond those detailed above, without the taxman trying to claim a slice. These are known as ‘potentially exempt transfers’.

All you have to do is live for seven years after making the gift.

If you die within seven years of making the gift, and the total value of the gifts is valued at less than the Inheritance Tax threshold, then it will be added to the value of your estate.

However, should the gifts be valued at more than the Inheritance Tax threshold, then either the person receiving the gift or the person managing your estate will need to pay Inheritance Tax on its value.

All simple so far, but since this is Revenue & Customs we are dealing with, there’s room for a bit of added complexity!

Should you die between three and seven years after making the gift, and the value of the gift is valued at more than the Inheritance Tax threshold, then the tax due is reduced on a sliding scale.

Don't forget your life insurance

If you have a life insurance policy, should you die, the payout to your relatives may actually be subject to Inheritance Tax.

Life cover is obviously important, but it can have repercussions for your IHT bill.

That’s because the payout will be added to the value of your estate.

What’s more, it can then take months before your family receives the cash. It’s all far from ideal.

However, you can have the policy written in trust.

This basically separates the policy from the rest of your estate, which means that there will be no tax to pay. It also helps to speed up the process of your family receiving the cash.
