Trusts are often misunderstood.
Some people think they are only for the ultra-wealthy. Others assume they are a tax loophole.
Many avoid them because they fear “complexity” or “HMRC attention”.
The reality is simpler.
Trusts are a control mechanism first. Tax efficiency is a consequence of good structure, not the starting point.
This article explains, at a high level, what it typically costs to:
- Set up a trust during lifetime
- Create a trust through a Will
- Maintain a trust year-to-year
- Deal with HMRC charges and IHT implications
All examples are anonymised and based on common UK scenarios involving property and business assets.
1. TWO MAIN TYPES OF TRUST PLANNING
Before costs make sense, the structure must be clear.
A. Lifetime Trusts (Set up while you are alive)
Assets are transferred into trust now.
B. Will-Based Trusts (Set up on death)
Assets move into trust only after death.
The costs and tax consequences are very different.
2. UPFRONT COSTS: LIFETIME TRUSTS
Legal and advisory costs
For a typical UK lifetime trust involving property or business interests:
Legal drafting and advice:
£2,000 – £6,000+
(Depends on complexity, number of assets, and number of trustees)
Additional work if business partners or deeds of trust are involved:
£1,000 – £3,000+
These are professional costs, not taxes.
HMRC upfront tax cost: Entry Charge
Lifetime trusts are subject to the Inheritance Tax “entry charge”.
How it works (simplified):
- Each individual has a £325,000 Nil Rate Band (NRB).
- Value transferred into trust above the NRB may be taxed at 20% immediately.
Example:
- £600,000 transferred into trust
- First £325,000 covered by NRB
- Remaining £275,000 taxed at 20%
Upfront IHT charge: £55,000
This is why lifetime trusts must be planned, not rushed.
Important:
- Not all assets are suitable.
- Reliefs may apply in some cases.
- Poorly timed trusts can be expensive.
3. ONGOING COSTS: LIFETIME TRUSTS
Once a trust exists, it must be maintained.
A. Annual trust tax returns
Required in most cases.
Especially where income or gains arise.
Typical cost:
£500 – £1,500 per year, depending on activity.
B. Trust Registration Service (TRS)
Mandatory registration with HMRC.
Ongoing updates required.
Typical cost:
- Initial registration: £250 – £500
- Updates: £100 – £300 as needed
C. Trustee administration
Record-keeping.
Trustee decisions.
Minutes and compliance.
Some trustees handle this themselves.
Others pay advisers.
Cost:
Variable.
Often overlooked.
D. Ten-year anniversary charge
Every 10 years, most lifetime trusts are reassessed for IHT.
Maximum charge: 6%
Based on value above the Nil Rate Band at that time.
This is often less than 40% IHT, but it must be budgeted for.
4. COSTS: WILL-BASED TRUSTS (NO LIFETIME TRANSFER)
Will-based trusts are often misunderstood.
They are:
- Cheaper upfront.
- Easier to implement.
- Less effective for IHT reduction.
Upfront cost
Included within a properly drafted Will.
Typical range:
£750 – £2,500, depending on complexity.
No lifetime IHT entry charge.
Tax position
Spouse trusts often benefit from spouse exemption.
IHT is deferred, not avoided.
Tax usually arises on second death.
Ongoing costs
Similar administration costs after death.
Trust tax returns may be required.
TRS registration applies.
5. “DO TRUSTS SAVE TAX?”
The honest answer: sometimes.
Trusts are excellent at:
- Controlling assets.
- Protecting families.
- Managing joint ownership.
- Preventing forced sales.
- Preserving value for future generations.
Trusts are less effective at:
- Eliminating IHT overnight.
- Fixing late planning.
- Solving poor asset structures.
The biggest IHT savings come from:
- Early planning.
- Correct asset selection.
- Growth being removed from the estate over time.
6. THE COST OF DOING NOTHING
This is rarely discussed.
If no trust planning exists:
- Assets pass outright.
- IHT can be 40%.
- Estates may need to sell property to pay HMRC.
- Families inherit tax problems, not wealth.
In many cases, the tax bill dwarfs the cost of planning.
7. THE REAL DECISION
The real question is not: “Are trusts expensive?”
It is: “Which cost am I choosing?”
Planned, predictable costs over time
or
A single, uncontrolled tax bill on death
Trusts are not for everyone.
But for property-heavy, business-linked estates, doing nothing is rarely neutral.
8. FINAL WORD
Trust planning is not about complexity. It is about foresight.
The earlier the conversation happens:
- The more options exist.
- The lower the tax friction.
- The more control is retained.
Late planning is always more expensive.
Transparency note
All figures above are indicative and based on current UK tax principles.
Actual costs depend on asset values, structure, reliefs, and timing. No tax outcome can be guaranteed.
