Moving to Britain as a Trustee? A Budget Relief Could Remove a Tax Obstacle

A technical Budget measure could remove a significant complication for some families moving to Britain. The government has announced relief from a Capital Gains Tax exit charge where an overseas trust briefly becomes UK resident because one or more trustees relocate here.

For an internationally mobile family, the issue can reach beyond the trust itself. A move may involve a UK home, new borrowing arrangements and decisions about which assets remain invested overseas. Uncertainty about the trust’s tax position can hold up the wider plan.

The change is narrowly targeted. Its potential importance lies in helping a qualifying family resolve one obstacle to relocation, rather than creating a general tax incentive for overseas wealth.

Why a trustee’s move can affect the whole arrangement

A person may act as trustee of a family settlement while also running a business, managing personal investments or planning a move for family reasons. Their trusteeship is a separate capacity, but a change in personal residence can affect the trust’s tax analysis.

For CGT purposes, section 69 of the Taxation of Chargeable Gains Act 1992 treats the trustees as a single person. The residence rules consider the trustees’ positions and, in some arrangements with both UK and non-UK trustees, the settlor’s residence at relevant times.

Consequently, one trustee moving to Britain does not automatically make every overseas trust UK resident. Equally, an overseas trust deed or foreign investment custodian does not, by itself, settle the question.

The starting point is an assessment of the actual arrangement. The new relief becomes relevant only once advisers establish that the relocation brings the trust within the circumstances described.

The problem arises when the trust subsequently leaves

The charge addressed by this measure is an exit charge. Under the existing framework, a trust ceasing UK residence can face CGT through a deemed disposal of relevant assets, even though those assets have not actually been sold.

HMRC’s Capital Gains Manual explains that the calculation uses market value immediately before the residence change. Which assets fall within the charge, and whether another exception applies, requires its own review.

This can create an awkward consequence of a relatively brief period of UK residence. The family may not have intended to sell investments or release cash, yet the change in the trust’s status can produce a tax question requiring funding.

That is the obstacle the Budget measure seeks to ease. It concerns the later departure of the trust from UK residence, rather than a general charge on the trustee arriving in Britain.

What HMRC has announced

The 28 October policy note describes relief where a trust becomes UK resident because one or more trustees move here and subsequently ceases UK residence during the same tax year or the following one.

The announced operative date applies to relevant exit charges arising on or after 28 October 2026. It should not be confused with a requirement that the trustee’s arrival must occur on or after that date.

The Budget’s tax legislation overview says the government will legislate through Finance Bill 2026–27. Advisers therefore need to follow the implementing provisions as well as the announced effect date.

The timing needs more care than a “one-year” label

HMRC’s detailed explanation uses the same or following tax year. A family should not replace that wording with an assumed 12-month period from arrival, nor with the end of the next calendar year.

The relevant dates concern when the trust becomes and ceases to be UK resident. They need to be established through the applicable rules and evidence. A proposed completion date for a house purchase does not determine them.

The individual’s residence assessment is also separate. HMRC’s residence guidance considers factors including time spent in the UK, work, homes and family ties. A mortgage application or stated intention to relocate is not a substitute for that analysis.

For a coordinated move, advisers should distinguish three dates: the individual’s relevant residence change, any change in the trust’s status, and the property transaction. They may interact, but should not be treated as interchangeable.

How this could affect a family’s relocation decision

Consider a hypothetical entrepreneur living overseas who is also a trustee of a family arrangement holding international investments. They intend to move to Britain with their family and buy a home using personal savings and mortgage borrowing.

Assume their tax advisers identify that the move would make the trust UK resident temporarily. Under the previous position, concern about the later exit charge could complicate the timing of the relocation and the household’s wider financial commitments.

If the announced relief applies to the proposed sequence, that particular obstacle may be reduced. The family can then assess the home purchase with a clearer understanding of the trust’s position.

That does not establish the result for every similar family. Advisers still need to determine why residence changes, whether the required conditions will be met and what other consequences arise. Any change to trusteeship or governance must also be legally valid and appropriate to the trust.

The practical benefit is greater clarity for a decision already under consideration. It is not a reason to rush a move or make a property commitment before the separate funding arrangements are workable.

Relief from an exit charge leaves other obligations in place

The announcement does not say that income or gains arising while a trust is UK resident become exempt. It also does not resolve the treatment of distributions, the individual’s foreign income or the tax consequences of purchasing a UK property.

HMRC’s general trust guidance explains that sales and transfers can create separate CGT consequences. Those transactions should not be assumed to receive relief simply because a later residence change might qualify.

Reporting remains another question. The guidance on trustees’ tax responsibilities covers records, returns and payment obligations. Advisers should establish what remains required during the relevant period, even if no exit charge ultimately falls due.

For a family office, this means reviewing the whole sequence of events. Removing one projected liability can help planning, but it does not replace the broader analysis.

The property-finance question starts with ownership

A family may describe its wealth as a single combined figure. A lender needs a more precise picture of the proposed borrower, income, deposit and assets available to support the transaction.

Personally owned savings, a discretionary trust interest and investments held by trustees are different resources. A trustee’s power to administer assets does not establish a personal right to spend or pledge them.

Where trust funds are proposed as a deposit, loan or security, the legal advisers must confirm the powers, purpose and approvals involved. The lender must then assess whether the arrangement fits its requirements.

Where the home is being bought personally using resources outside the trust, keep that funding route clear. The trust may explain part of the relocation background without being either the property owner or the borrowing party.

Willow’s role is to assess the property-finance options for the confirmed ownership and funding arrangements. A favourable tax conclusion does not itself establish mortgage affordability, a valuation or an acceptable security structure.

What the professional team should establish early

The tax adviser can identify the relevant residence changes, assess the announced relief and follow the legislative detail. The trust’s legal advisers can establish the governance position and any permissions needed for the proposed arrangements.

The financing review can then use a consistent account of who is buying, where the deposit comes from, which income supports borrowing and when funds are required. If any part depends on a future distribution, asset sale or approval, that dependency should be explicit.

For international income, establish the currency, source and evidence available. For assets offered as security, establish ownership and existing commitments. The purpose is to present the lender with an accurate case rather than a headline family-wealth figure.

These discussions can progress alongside the tax work. The borrowing plan should remain conditional on unresolved matters, with the conveyancer aware of any issue that could affect exchange or completion.

A narrow measure with potential importance for individual families

HMRC expects only a very small number of offshore trusts to be affected and no significant macroeconomic impact. That limits the case for presenting this as a broad shift in demand for UK homes.

For an affected family, however, the consequence may be meaningful. A targeted relief can remove a difficult issue from a move involving family, business interests and substantial assets across jurisdictions.

Willow’s assessment is that this is a useful prompt for international tax advisers, family offices and wealth managers to revisit relevant relocation cases. The next step is to establish whether the relief changes the client’s position, then align the UK property funding with that confirmed plan.
