Inheritance Tax (IHT) raises more than £8 billion a year for HMRC, and that figure is rising. With the nil-rate band frozen at £325,000 since 2009 and property prices continuing to climb, more families are being drawn into the IHT net without realising it. The tax is avoidable in many cases, yet the same mistakes come up time and again.
Whether your estate is worth £400,000 or £4 million, understanding the most common IHT planning errors could make a significant difference to what your family actually receives. Here are the seven mistakes we see most often, and what you can do about them.
Many families dismiss IHT as something for the very wealthy. The reality in 2026 is quite different. If you own a home in or around any major UK city, have a pension, savings, investments, and a few years of accumulated assets, you may already be closer to the threshold than you think.
The nil-rate band sits at £325,000 and is frozen until at least 2031. The residence nil-rate band adds a further £175,000 when you leave your home to direct descendants, giving a potential combined allowance of £500,000 per person or £1 million for a married couple. But estates worth more than £2 million begin to lose the residence nil-rate band at £1 for every £2 over the threshold. With rising house prices, this taper catches more families every year.
The first step in good IHT planning is simply knowing where you stand. Many people have never added up the full value of their estate.
Dying without a will means your estate is distributed according to the rules of intestacy, which rarely align with your wishes and can result in a larger IHT bill than necessary. But having an outdated will can be equally damaging.
A will drafted before a second marriage, the arrival of grandchildren, a significant change in asset values, or a major shift in tax law may no longer reflect your intentions or your tax position. Given the pension IHT changes coming into effect in April 2027, any will that was written when pensions were considered outside the estate for IHT purposes should now be reviewed as a matter of priority.
A well-structured will, aligned with your wider estate plan, is one of the most cost-effective IHT planning tools available.
Giving away assets during your lifetime is one of the most straightforward ways to reduce your taxable estate, but the rules around gifting are widely misunderstood. Many people believe that any gift made more than three years before death is free of IHT. This is not correct.
Most gifts only fall fully outside your estate after seven years. In the years between making a gift and death, a sliding scale of taper relief may apply, but only where the gift exceeds the nil-rate band. Gifts within seven years that do not exceed that band are still counted against it. The practical implication is that gifting should begin early, not when someone is already in poor health.
Each individual also has an annual gifting exemption of £3,000, which can be carried forward for one year if unused, and can make small, regular gifts out of surplus income completely free of IHT, provided certain conditions are met.
This is one of the most common IHT planning errors we see, and it can be costly. Many families attempt to reduce their taxable estate by transferring ownership of the family home to their children while continuing to live there rent-free. HMRC treats this as a gift with reservation of benefit, meaning the property remains in the estate for IHT purposes regardless of the transfer.
For this strategy to work as intended, either the original owner must move out entirely or pay a genuine market rent to the new owners. There are more nuanced approaches available, such as gifting a share of the property, but these require careful structuring and professional advice to be effective.
If your estate plan includes property gifting, it is worth having it reviewed by an independent adviser. Contact our team for a no-obligation conversation.
Thousands of families pay IHT on life insurance payouts every year, simply because the policy was not written in trust. If a life insurance policy pays out directly to your estate rather than into a trust, the proceeds are added to your estate and potentially taxed at 40%.
Writing a policy in trust takes the payout outside your estate entirely. It also means the money can reach your family more quickly, without waiting for probate. This is a simple step that costs nothing to arrange but can save tens of thousands of pounds. It is also something that can be done at any time, not just when a policy is first taken out.
Until recently, many families structured their finances specifically to preserve pension wealth, drawing from ISAs and savings first and leaving pensions untouched as an IHT-efficient legacy. From April 2027, that approach will need to be reconsidered.
Unused pension funds will be brought into the scope of IHT, which means estates that were previously under the threshold could face a significant tax liability. The common IHT mistake here is inaction, assuming that because this change is still over a year away, there is no urgency to act. The decisions that affect your IHT position in 2027 need to be made now, not once the rules have changed.
Reviewing your expression of wishes, reconsidering your drawdown strategy, and revisiting your overall estate plan are all steps worth taking without delay.
The biggest Inheritance Tax mistake of all is procrastination. IHT planning takes time to be effective. The seven-year rule on gifts, the careful structuring of trusts, and the alignment of wills with pension nominations and wider estate plans all require lead time. Decisions made in ill health, or in the final years of life, have far fewer options available to them.
HMRC has also significantly increased its scrutiny of IHT returns in recent years, using increasingly sophisticated tools to identify errors and inconsistencies. Families who have not planned carefully can face not only a larger tax bill but also a difficult and stressful administrative process at an already difficult time.
The good news is that for most families, early and well-structured planning can make a very meaningful difference to the amount of wealth that passes to the next generation.
