Generational Wealth Transfer Strategies for Internationally Mobile Families

Wealth transfer — the process of passing assets from one generation to the next — is one of the most significant financial planning challenges facing high-net-worth families. It is also one of the most underestimated. Many families focus intently on building wealth and give comparatively little structured attention to how it will be preserved and passed on.

For internationally mobile families, the challenge is compounded by multiple jurisdictions, different legal systems, and the constant possibility of residence changes that alter the tax landscape mid-plan.

This guide examines the main tools available, how they interact with an international lifestyle, and where early planning makes the most material difference.

The Scale of the Opportunity

Analysts estimate that approximately £5.5 trillion in private wealth will pass between UK generations over the next twenty years — a figure sometimes described as the "Great Wealth Transfer." Globally, the sums involved are far larger.

For the generation currently holding this wealth — typically individuals in their fifties, sixties, and seventies — the window for active tax planning is open now, not at the point of death. Most of the most effective wealth transfer strategies require time to work; a gift made ten years before death is treated differently by IHT than a gift made ten months before death. The longer the planning horizon, the better the outcome.

The Basics: Gifts and the Seven-Year Clock

The simplest wealth transfer tool is an outright gift. Under UK rules, a gift from one person to another (other than between spouses) is a Potentially Exempt Transfer (PET) for IHT purposes. If the donor survives for seven years after making the gift, it falls out of their estate entirely and no IHT is payable.

The annual £3,000 exemption is the most underused tool in UK IHT planning. Each individual can give away £3,000 per tax year free of IHT — immediately exempt, with no seven-year clock. Over twenty years, a couple can give away £120,000 under this exemption alone, plus all the investment growth on those gifts in the hands of the recipients.

Other exempt gifts include: gifts from regular income (where the gift is genuinely surplus to the donor's income needs and forms part of a regular pattern); gifts on marriage (up to £5,000 to a child, £2,500 to a grandchild, £1,000 to others); gifts for the maintenance of dependent relatives.

Used consistently and documented carefully, these exemptions can achieve substantial IHT-free transfers without any complex structure.

Trusts as Wealth Transfer Vehicles

Trusts allow you to transfer wealth out of your estate while retaining a degree of control over how the assets are managed and distributed. The main trust structures used in UK wealth transfer planning are:

Discretionary Trusts: Assets are placed in trust for a class of beneficiaries (typically children and grandchildren). The trustees have discretion over who receives income and capital, when, and in what amounts. There is an immediate IHT charge if the transfer into trust exceeds the nil-rate band (currently £325,000); a ten-year periodic charge of up to 6% of the trust's value; and exit charges when assets leave the trust. Despite this, trusts can be highly effective — particularly when combined with qualifying Business Property Relief investments. Note that from 6 April 2026, BPR and APR are subject to a combined £2.5 million cap at 100% relief (raised from the £1 million originally announced in the October 2024 Budget, increased to £2.5 million in December 2025, and transferable between spouses/civil partners); assets above that threshold attract only 50% relief (a 20% effective IHT rate) rather than full exemption. AIM and other unlisted shares receive 50% relief only and do not use the £2.5 million allowance.

Discounted Gift Trusts (DGTs): The donor transfers a lump sum into a trust and retains the right to receive fixed regular income payments for life. The "discount" is the actuarially calculated value of those retained income payments — it immediately reduces the IHT value of the gift. The remainder of the trust fund benefits from the seven-year PET clock. DGTs are particularly useful for donors who need some income but want to reduce their estate.

Loan Trusts: The donor lends money to the trust at zero interest. The loan is a liability of the trust and an asset of the estate — but only the original loan value is in the estate, not the investment growth. Over time, the investment returns inside the trust accumulate outside the estate. The loan can be written off gradually or left to be repaid from the trust on death. This is a more conservative structure than a DGT but has no complex actuarial element.

The Family Investment Company

The Family Investment Company (FIC) is a private limited company used as a vehicle for family investments. It has grown significantly in popularity over the last decade.

In a typical FIC structure, the parents subscribe for shares or lend money to the company at the outset. The children (or grandchildren) receive shares — often structured as growth shares or a different share class — so that future investment growth accrues in their hands rather than the parents' hands.

The FIC is subject to corporation tax on its investment gains and income (currently 25% for profits over £250,000). This is lower than the 45% additional rate that would apply if the same investments were held personally. Retained profits within the FIC can compound at the corporate rate, creating a significant efficiency compared to personal holding.

The FIC does not create an immediate IHT saving — the shares held by the parents are still in their estate at market value. However, by directing growth into the children's share classes, the estate's value is progressively reduced over time without triggering IHT events.

The International Dimension

For internationally mobile families, every wealth transfer strategy has an additional layer of complexity: the jurisdictions of the family members involved.

A non-UK domiciled parent receiving a gift, or a UK-resident child receiving a gift from a non-domiciled parent, creates questions about which country's IHT applies to the gift and the gifted assets. The domicile (now, for IHT purposes after April 2025, the Long-Term Resident status) of the donor determines UK IHT exposure — but it does not determine the recipient country's tax treatment.

If assets are held in a trust and the settlor becomes non-UK resident, the tax treatment of the trust can change significantly. Offshore trust rules require careful ongoing monitoring.

Property in multiple jurisdictions requires an international estate plan that coordinates structures across legal systems. A discretionary trust that works elegantly for UK assets may not translate to Spanish real estate or UAE bank accounts without additional legal architecture.

What Not to Do

Do not delay. The most common wealth transfer planning mistake is waiting. The IHT-free gift period (PETs) requires seven years. The longer you wait to make gifts, the less likely it is that the full seven years elapse before death.

Do not confuse control with ownership. Some families want to retain economic benefit from assets they have "given" to children. The UK rules are strict: if you give away an asset but continue to benefit from it, it remains in your estate as a "gift with reservation of benefit." The gift is treated as though it never happened.

Do not plan in one jurisdiction and ignore the others. An estate plan that efficiently reduces UK IHT on assets held through a UK trust may create unforeseen tax liabilities in the country where the next generation lives, or in the jurisdiction where the trust is registered.

How Global Investments Can Help

Generational wealth transfer planning requires a long-term perspective, careful coordination between advisers, and a clear understanding of how different jurisdictions interact. Global Investments works with internationally mobile families to develop coherent transfer strategies that address IHT, cross-border legal ownership, trustee selection, and family governance — with a focus on preserving wealth across generations rather than reacting to crises.

We work with tax counsel, trust specialists, and estate planning lawyers across our key markets to ensure that strategies are properly implemented rather than remaining as intentions.
