An interest in possession trust gives one named beneficiary an automatic right to the income from the trust’s assets, or the right to live in a property the trust owns, while the underlying capital is held for someone else who will inherit it later. A common example: a surviving spouse takes the rent from an investment property or lives in the family home for the rest of their life, and when that interest ends the property passes to the children. The structure is straightforward in outline, but its tax treatment split in two on 22 March 2006, and which side of that date the interest falls on drives almost everything that follows.
Who Is Involved
Four roles run the arrangement. The settlor creates the trust and puts assets into it. The trustees hold legal title and manage those assets, owing duties of care, loyalty, and impartiality to every beneficiary.1Cornell Law Institute. Fiduciary Duties of Trustees The life tenant (sometimes called the income beneficiary) holds the interest in possession itself. The remaindermen take the capital once the life tenant’s interest ends.
Impartiality matters in practice because the life tenant wants income now and the remaindermen want the capital preserved for later. Trustees cannot hand assets to the life tenant, and they cannot park everything in low-yield cash to inflate the eventual capital either.
What the Life Tenant Actually Receives
The life tenant is entitled to the net income after the trustees deduct expenses properly chargeable to income, such as management fees or insurance on trust property.2GOV.UK. Beneficiaries – Paying and Reclaiming Tax on Trusts That income might be dividends from shares, interest on cash deposits, or rent from a let property.
Where the trust holds a home, the “interest” often takes a different form: the life tenant lives in the property rent-free rather than receiving cash. The remaindermen then take the property itself when the life interest ends.
The 22 March 2006 Dividing Line
The Finance Act 2006 rewrote the inheritance tax treatment of these trusts, and every interest in possession now sits on one side or the other of that date.
Interests Existing Before 22 March 2006
If the life tenant’s interest existed before 22 March 2006, the old regime still governs. The trust property is treated as belonging to the life tenant for inheritance tax under section 49(1) of the Inheritance Tax Act 1984.3GOV.UK. IHT Treatment From 22 March 2006 – Qualifying Interests in Possession On the life tenant’s death, the trust assets are added to their estate and taxed there. Lifetime transfers out of the trust to individuals count as potentially exempt transfers, and the trust is not subject to the ten-yearly periodic charge.
Interests Created on or After 22 March 2006
Interests created on or after that date are only treated as part of the beneficiary’s estate if they fit one of three categories: an immediate post-death interest, a disabled person’s interest, or a transitional serial interest.4GOV.UK. Interests in Possession – Finance Act 2006 and the New Trust Regime Anything outside those categories falls into the relevant property regime and is taxed like a discretionary trust, with periodic and exit charges.
An immediate post-death interest arises where a will or intestacy creates a trust and the beneficiary’s entitlement begins on the death of the person who owned the assets. This is the usual route for a new interest in possession to keep favourable inheritance tax treatment. A transitional serial interest generally protects a successor, often a surviving spouse, who inherits an interest from the original life tenant of a pre-2006 trust.
Inheritance Tax
For a qualifying interest, the trust property is included in the life tenant’s estate on death. Inheritance tax is charged at 40% on the combined value of personal and trust assets above the nil-rate band, which has been frozen at £325,000 since 2009 and will remain frozen until at least April 2030.5GOV.UK. Inheritance Tax Thresholds and Interest Rates
For a trust in the relevant property regime, inheritance tax is charged differently. A periodic charge applies every ten years on the net value of the trust the day before the anniversary, and the calculation takes in the trust’s value, transfers the settlor made in the seven years before creating it, and property that left the trust in the previous decade.6GOV.UK. Trusts and Inheritance Tax The maximum effective rate is 6%, and many trusts pay less. Exit charges apply when property leaves the trust between anniversaries.
Income Tax
Trustees pay income tax at the basic rate: 20% on most income and 8.75% on dividends, with the dividend rate rising to 10.75% from 6 April 2026.7GOV.UK. Trusts and Income Tax The life tenant then reports the same income on their own Self Assessment return and takes a credit for the tax the trustees have already paid.2GOV.UK. Beneficiaries – Paying and Reclaiming Tax on Trusts
For a basic rate taxpayer, the credit clears the bill. A higher or additional rate taxpayer pays the difference between the basic rate and their own marginal rate. A life tenant whose total income falls below the personal allowance can reclaim some or all of the tax the trustees paid.
If you are a life tenant, the trustees must give you a statement showing the sources of income, the amounts, and the tax already paid. HMRC’s Form R185 is the standard document for this.8GOV.UK. Trustees – Tax Responsibilities
Capital Gains Tax
When trustees dispose of an asset that has gone up in value, capital gains tax applies. The rate for trustees is 24% on all chargeable gains, whatever the asset.9GOV.UK. Capital Gains Tax – Rates and Allowances Trustees get an annual exempt amount of £1,500, half the individual figure.10GOV.UK. Capital Gains Tax Rates and Allowances
A qualifying interest in possession has one notable advantage here. When the life tenant dies, the trust assets are uplifted to market value at the date of death, wiping out the accrued gain, in the same way assets owned outright are uplifted on death. Trusts in the relevant property regime do not get this uplift automatically, which can leave a larger CGT bill when the trustees eventually sell.3GOV.UK. IHT Treatment From 22 March 2006 – Qualifying Interests in Possession
Setting the Trust Up
A valid trust needs a formal deed identifying the settlor, the trustees, the life tenant, and the remaindermen. The deed should specify which assets are being settled, the scope of the life tenant’s entitlement, any powers given to the trustees (a power to advance capital, for example), and what brings the life interest to an end.
Execution follows the Law of Property (Miscellaneous Provisions) Act 1989: an individual signs in the presence of a witness who attests the signature, and a party to the deed cannot witness another party’s signature.11Legislation.gov.uk. Law of Property (Miscellaneous Provisions) Act 1989 Spousal witnesses are best avoided to reduce the risk of later challenge.
After signing, the settlor has to transfer the assets into the trustees’ names. Bank and investment accounts need their registered holders updated. Land needs the trustees registered as the new proprietors at the Land Registry. Skipping this step leaves the trust technically unfunded and the life tenant’s rights unenforceable. Legal fees for drafting typically start around £1,500 and rise with complexity.
Registering With HMRC
Most trusts must be registered on HMRC’s Trust Registration Service. Taxable trusts have 90 days from becoming liable for tax. Non-taxable trusts created after September 2022 also have 90 days from creation.12GOV.UK. Register a Trust as a Trustee Registration requires details for the settlor, every trustee, and every identifiable beneficiary, including names, dates of birth, and addresses.13GOV.UK. Manage Your Trust’s Details Changes, such as a new trustee, must be updated within 90 days. Missing the deadlines can bring penalties.
When the Interest Ends
The life interest ends when the deed says it does. Death of the life tenant is the usual trigger, and the right to income stops at that moment. Some deeds pick other events instead, such as remarriage, moving out of a trust-owned property, or reaching a specified age. Once the interest ends, the trustees distribute the capital to the remaindermen as the deed directs.
The tax outcome at that point tracks the category the trust fell into. For a qualifying interest, the trust property is added to the life tenant’s estate for inheritance tax; the remaindermen take the assets and the estate carries the bill. For a trust in the relevant property regime, an exit charge may apply, calculated by reference to the time since the last ten-year anniversary. Trustees also file a final tax return for the period up to the date the trust ended, reporting any income and gains for that closing period. Once the capital has been transferred and the tax settled, the remaindermen hold the assets outright and the trust is done.
