How Disabled Trusts Work and the Key Benefits for UK Families

• A disabled person’s trust does not affect any means-tested benefits like Universal Credit, and Housing Benefit for a qualifying beneficiary.
• It sits outside the usual trust tax regime, so there are no 10-year periodic charges or immediate 20% tax charge over £325,000 that apply to ordinary discretionary trusts.
• The beneficiary must qualify under the Schedule 1A Finance Act 2005 test, which covers eleven disability benefits and mental incapacity.
• Trust assets form part of the beneficiary’s estate for inheritance tax, so the normal nil-rate band rules apply on their death.
• Good trustees matter as much as good drafting. Choose people who know the beneficiary and can commit for the long term.

It is a trust that holds assets for a disabled beneficiary without those assets counting as theirs for benefits or care funding. Trustees decide how and when to apply the money for the beneficiary’s benefit. The beneficiary never owns the capital directly, which is the whole point.

These structures are sometimes called Section 89 trusts, vulnerable beneficiary trusts, or disabled person’s trusts. The name changes. The purpose does not.

HMRC’s rules on trusts for vulnerable people set the test. A beneficiary qualifies if they are eligible for any of the following, even if they are not currently claiming:

• Personal Independence Payment (PIP)
• Disability Living Allowance (DLA), at the middle or higher care rate, or the higher mobility rate
• Attendance Allowance
• Constant Attendance Allowance
• Armed Forces Independence Payment
• Industrial Injuries Disablement Benefit
• Adult Disability Payment (Scotland)
• Child Disability Payment (Scotland)
• Scottish Adult Disability Living Allowance
• Pension Age Disability Payment
• Disability Living Allowance for children

A beneficiary also qualifies if they cannot manage their own affairs because of a mental disorder under the Mental Health Act 1983.

“Eligible” is the key word, not “receiving”. Many families assume their disabled child must already be claiming PIP. That is not the case.

Ordinary discretionary trusts face a periodic charge of up to 6%  on the value over £325,000 every ten years. On a £500,000 trust, that can cost around £10,500 a decade.

A disabled person’s trust escapes these charges. HMRC instead treats the beneficiary as if they already owned the trust assets for inheritance tax purposes. Nothing is taxed while the trust runs.

On the beneficiary’s death, their own nil-rate band £325,000 and residence nil-rate band up to £175,000  apply in the usual way.

Trustees also claim more generous capital gains and income tax treatment through the vulnerable beneficiary election on HMRC form SA905.

This is a significant departure from how standard discretionary trusts are taxed. In practical terms, a qualifying disabled person’s trust is treated more like a bare trust for inheritance tax purposes, with assets aligned to the beneficiary’s personal tax position rather than the punitive trust rates.

• Means-tested benefits stay intact. Our understanding is that assets inside the trust are not counted when the DWP or the local authority assesses Universal Credit, ESA, Housing Benefit, or care contributions. Trustees can still spend trust money on holidays, home adaptations, equipment, or top-up care. Lump sums paid straight into the beneficiary’s account can undo the protection, so how the trust is run matters as much as how it is written. However state benefits are a complex area which are often individually determined so you should double check with a government official the impact of any assets put into a disabled persons trust on their state benefits.
• No 10-year or exit charges. The trust sits outside the normal trust tax regime, so a decade of periodic charges does not eat into the family’s provision. No immediate 20% change if placing over £325,000 into the trust.
• Better capital gains and income tax position. Trusts with vulnerable beneficiaries qualify for a higher annual CGT exemption of £3,000 rather than £1,500 and can elect to pay income tax at the beneficiary’s personal marginal rate rather than the higher trust rate of 45%.
• Protection from financial abuse. Trustees act under a legal duty, not a family suggestion. That matters where the beneficiary lacks capacity or could be pressured into handing over money.
• Continuity across a lifetime. Disabled beneficiaries often move through several care settings and benefit regimes over decades. A trust is one stable legal wrapper that outlasts those changes 125 years.
• Protection if benefits become means tested in the future. We recommend drip feeding the needed amount rather than holding a large amount in case of any future changes from the government means testing to reduce benefits.

Many families set up a disabled person’s trust inside a will. It takes effect on the parent’s death, receives the inheritance that would otherwise pass to the disabled child directly, and uses the parent’s normal nil-rate band on the way in.
Bluebond recommends that you set up the trust during your lifetime as they are useful in three key situations: grandparents who want to contribute directly, families who have received a personal injury settlement, or parents who want to encourage wider family gifts into one protected structure.

Families often start with the wrong question. They ask “how do we reduce inheritance tax?” instead of “who will look after our child when we are gone, and what do they need to live well?”. The tax position follows from the answer to the second question, not the first.

Two mistakes come up again and again. The first is using a generic discretionary trust template from a will-writing service and assuming it will protect benefits. It usually will not qualify for the special tax treatment, and the trustees hit unexpected charges years later. The second is leaving assets to the disabled child outright, which wipes out means-tested benefits overnight and can trigger a full care-funding reassessment.

19 out of 20 Bluebond clients legitimately pay zero inheritance tax. The structures that deliver that outcome always start with the family, not the tax code.

Before drafting anything, work through these questions with a specialist adviser who covers both tax and private client law.

• You need to confirm does the beneficiary qualify under the Schedule 1A Finance Act 2005 test?
• Will the trust be created by will, during your lifetime, or both?
• Who will the trustees be, and is there a succession plan when they step down?
• What should the letter of wishes say about care, lifestyle, and end-of-life preferences?
• Which assets will flow into the trust, and is the source of each clearly documented?
• Who will handle annual HMRC compliance, including the Trust Registration Service and the vulnerable beneficiary election?

General information is not personal advice. A specialist review of your own situation is worth the fee many times over.

A disabled person’s trust is one of the most powerful structures in UK estate planning for families with a vulnerable dependant, and one of the most specific about how it needs to be drafted and managed. Getting the conditions right is the difference between the trust delivering everything the family hoped for and leaving them exposed.
