If you are planning ahead for your family, an immediate post-death interest trust may be an option worth considering.
This type of trust is often used in wills where someone wants to make sure a loved one can benefit after death, while also keeping control over where the underlying assets pass in the future. In many cases, it is used to provide for a surviving spouse or partner during their lifetime, with the capital then passing to children or other chosen beneficiaries later on.
At Evans Legacy Planning, we explain trusts in plain English. We help clients across England and Wales understand how immediate post-death interest trusts work, when they may be suitable, and how they can fit into a wider estate plan alongside a Will, broader trust planning, and a Lasting Power of Attorney.
An immediate post-death interest trust, often shortened to IPDI trust, is a type of trust that usually arises under a will or intestacy after someone dies.
HMRC says an immediate post-death interest applies where the beneficiary becomes entitled to the interest in possession on the death of the testator or intestate, and where the trust is not a bereaved minor’s trust or disabled person’s interest. HMRC also explains that a person has an interest in possession when they have a present right to the income or enjoyment of the trust property.
In plain English, this usually means one person has the right to benefit from the trust assets straight away after death, often by receiving income from the assets or by having the right to live in a property, while the capital itself is preserved for other beneficiaries later.
Because of that, immediate post-death interest trusts are often described as a form of life interest trust used in wills.
A common example is where someone wants to leave their share of the family home or other assets in trust.
The surviving spouse or partner may be given the right to benefit from those assets during their lifetime. After that person dies, the assets then pass to the final beneficiaries named in the will, such as children or grandchildren.
This can help where the person making the will wants to do two things at once:
provide properly for a loved one after death
keep control over who ultimately inherits the capital
That balance is one of the main reasons why immediate post-death interest trusts are commonly used in estate planning.
Every family is different, but there are several common reasons why someone may consider an IPDI trust.
One of the most common uses of an immediate post-death interest trust is to provide for a surviving spouse or partner after the first death.
This may allow that person to continue benefiting from certain assets, such as income from investments or the right to occupy a property, without giving the whole capital away outright.
Some clients want to make sure their children ultimately inherit part of the estate, particularly where there are concerns about remarriage, blended families, or assets passing outside the bloodline in the future.
An immediate post-death interest trust can help provide for one person first, while preserving control over who receives the capital later.
Where there are children from a previous relationship, estate planning often needs extra care.
A trust of this kind may help where someone wants their current spouse or partner to be looked after, but also wants to make sure that children from an earlier relationship remain protected as final beneficiaries.
Leaving assets outright can sometimes be too simplistic for more complex family situations.
An IPDI trust can offer a more structured arrangement by separating who benefits now from who inherits later. That extra structure can be valuable where clarity and long-term planning matter.
This type of trust is often considered where:
you want to provide for a spouse or partner during their lifetime
you want children or other beneficiaries to inherit later
your family circumstances are more complex than a simple first marriage with adult children
you want more control over what happens to specific assets after your death
you are trying to balance flexibility, protection and fairness in your will
It is not right for everyone, but it can be very useful in the right circumstances.
Not all trusts work in the same way.
An immediate post-death interest trust is different from a fully discretionary trust because the main beneficiary has an immediate right to benefit. HMRC’s guidance distinguishes between an interest in possession, where there is a present right to enjoyment, and trusts where beneficiaries only have the right to be considered if trustees choose to distribute benefits.
It is also different from trusts for bereaved minors or disabled persons, which have their own separate inheritance tax treatment. HMRC identifies immediate post-death interests as a distinct category for inheritance tax purposes.
That is why it is important to choose the right trust based on the family’s actual goals, rather than using a one-size-fits-all approach.
Inheritance tax treatment can be one of the reasons this type of trust is considered, but it is important not to oversimplify it.
HMRC treats immediate post-death interest trusts as a recognised category of qualifying interest in possession trust. Trustees may also have reporting obligations when the beneficiary’s qualifying interest comes to an end on death, for example through form IHT100b in the appropriate cases.
The exact tax position will depend on the facts, the assets involved, who the beneficiaries are, and the wider estate planning context. Trust planning should never be presented as a guaranteed tax fix. It needs to be looked at properly and in context.
With trusts, wording matters.
A trust in a will needs to be drafted carefully so it reflects what you actually want to happen. That includes:
who benefits immediately
what rights they have
who receives the capital later
who the trustees are
what powers the trustees should have
Even a good idea can cause problems if the will is unclear or too loosely drafted. Good estate planning is not just about having a document in place. It is about having the right document, drafted properly, to work for your family.
This type of trust should usually be looked at as part of a full estate plan rather than in isolation.
That wider planning may include:
a professionally prepared Will
advice on trust planning
regular reviews as family, assets and wishes change over time
A joined-up plan gives you the best chance of making sure your wishes are carried out clearly and your family is better protected.
