Disabled Person's Trusts: Tax Treatment and Why They're Different
A trust set up for a disabled beneficiary gets meaningfully better Inheritance Tax, Capital Gains Tax and income tax treatment than an ordinary discretionary trust — provided it meets HMRC's specific qualifying conditions.
Why Disabled Person's Trusts Get Special Treatment
Ordinary discretionary trusts are subject to a specific Inheritance Tax regime designed to prevent wealth being sheltered indefinitely in trust structures — including a charge every 10 years on the trust's value above the nil rate band, and "exit charges" when capital leaves the trust. Parliament created a more favourable regime specifically for trusts benefiting disabled people, recognising that these trusts typically exist to provide essential lifetime support and protection rather than as a general tax-planning vehicle.
Qualifying as a "Disabled Person's Trust"
To access the favourable regime, both the beneficiary and the trust structure itself need to meet specific conditions:
The beneficiary must meet HMRC's definition of disabled
| Qualifying route | Detail |
|---|---|
| Mental disorder | Someone who, because of mental disorder within the meaning of the Mental Health Act, is incapable of administering their own property or managing their own affairs |
| Qualifying disability benefit | Receipt of certain benefits, such as the daily living component of Personal Independence Payment (PIP) at the enhanced rate, Attendance Allowance, or equivalent benefits |
| Physical disability | Meeting relevant tests around physical incapacity in some circumstances |
The trust itself must meet structural conditions
Broadly, the trust must ensure that during the disabled beneficiary's lifetime, if any of the trust's capital is applied, at least half of the amount applied must go to the disabled beneficiary themselves (rather than being freely distributable to other beneficiaries at the trustees' discretion) — this is what distinguishes a qualifying disabled person's trust from an ordinary, fully discretionary trust that merely happens to include a disabled person among a wider class of potential beneficiaries.
Inheritance Tax Treatment Compared
| Feature | Ordinary discretionary trust | Qualifying disabled person's trust |
|---|---|---|
| 10-yearly periodic charge | Applies, on value above available nil rate band | Does not apply during the disabled beneficiary's lifetime |
| Exit charges when capital leaves | Applies | Does not apply during the disabled beneficiary's lifetime |
| Treatment on the disabled beneficiary's death | Trust assets generally not part of their estate | Trust assets generally treated as part of the disabled beneficiary's own estate |
This last point is important to understand fully — the favourable lifetime treatment comes with the trade-off that the trust assets are usually brought into the disabled beneficiary's own estate for Inheritance Tax purposes when they die, potentially using up their own nil rate band and residence nil rate band. For many families, this trade-off is still clearly worthwhile given the significant lifetime charges avoided, but it's a genuine feature of the regime worth understanding rather than assuming the trust is entirely IHT-free forever.
Capital Gains Tax: The Increased Annual Exempt Amount
Ordinary trusts generally receive a reduced CGT annual exempt amount compared to an individual (historically set at half the individual rate, split between multiple trusts created by the same settlor in some circumstances). A qualifying disabled person's trust, by contrast, can potentially access the full individual annual exempt amount rather than the reduced trust rate, subject to meeting the qualifying conditions — meaningfully increasing the amount of gains that can be realised within the trust each year without triggering a CGT charge.
Income Tax Within the Trust
Income tax treatment for disabled person's trusts can also differ from ordinary discretionary trusts, with income often able to be treated more favourably depending on how the trust is structured and whether income is mandated directly to the disabled beneficiary or accumulated within the trust — the specific position depends on the trust deed's terms and should be reviewed with a specialist trust and tax adviser at the point of setting up or reviewing the trust.
Protecting Means-Tested Benefits and Care Funding
A major practical reason families set up disabled person's trusts, alongside the tax benefits, is to protect a disabled beneficiary's eligibility for means-tested support:
- Universal Credit and other means-tested benefits generally assess a claimant's own capital and income — assets properly held in a trust, rather than directly owned by the disabled person, are often disregarded from this assessment, though the specific disregard rules vary by benefit.
- Local authority care funding assessments similarly look at a person's own assets when assessing contribution towards care costs — trust assets not directly owned by the disabled person can, again subject to specific rules, be treated differently from directly held savings or inheritance.
This benefit-protection dimension is often the primary driver for setting up the trust in the first place, with the favourable tax treatment as an important secondary benefit — getting specialist welfare benefits advice alongside the trust and tax planning is essential, since getting the trust structure wrong can inadvertently jeopardise both the tax treatment and the benefit protection intended.
Common Scenarios
| Scenario | Why a disabled person's trust is used |
|---|---|
| Parents/grandparents providing for a disabled child in their will | Avoids a direct inheritance disqualifying the child from means-tested benefits, while still providing funds for their support |
| Personal injury or clinical negligence compensation | Protects a disabled claimant's damages award from directly affecting benefit eligibility, while providing funds for ongoing care needs |
| Family wealth planning for a disabled family member | Combines favourable IHT/CGT treatment with structured, trustee-managed support tailored to the beneficiary's needs |
Setting up a disabled person's trust correctly — meeting both the beneficiary definition and the structural conditions — requires specialist legal and tax drafting; getting it wrong can mean losing access to the favourable regime entirely and defaulting to ordinary discretionary trust treatment instead.
