Why Ultra-High-Net-Worth Families Are Turning to Family Offices for Wealth Management

Ultra-High Net Worth Families have been increasingly relying on family offices to navigate the complex landscape of tax planning and multi-generational wealth preservation. With IHT charged at 40% on estates above the nil rate band, effective planning strategies are of paramount importance for families seeking to transfer substantial wealth across generations efficiently.

Customised Wealth Management Solutions

Traditional banking cannot adequately address the multifaceted requirements of ultra-high net worth families. These families require customised solutions which integrate investment management, tax planning, estate structuring, philanthropy and family governance within a cohesive framework. Here, a family office serves as a central hub to provide comprehensive approach to delivering bespoke services aligning with family values and their unique circumstances to achieve their long-term objectives.

High IHT Rates Challenge for Wealthy Families

UK Inheritance tax legislation is complicated and imposes significant challenges for wealthy families, particularly with the nil-rate band of £325,000 and the residence nil-rate band (RNRB) of up to £175,000 per individual. Both are transferable between spouses or civil partners. In combination, a married couple or civil partners can currently achieve up to £1 million of allowances if the RNRB conditions are met, though the RNRB is reduced by £1 for every £2 that the net estate value exceeds £2 million. Families with estates exceeding these thresholds face substantial tax liabilities in absence of proper tax planning.

Family offices provide the necessary expertise to implement comprehensive IHT mitigation strategies which go beyond exemption use, encompassing well-planned trust structures, Business Property Relief (BPR) at 100% or 50%, subject to strict conditions including a minimum two-year ownership period, the requirement that the business must be trading (not investment), and restrictions on excepted assets which can affect the available and international considerations which align with current legislation and HMRC guidance.

Planning must be evidenced, commercially justifiable and regularly reviewed to ensure ongoing compliance. Key strategies encompass loan trust arrangements that freeze the value of the loan in the lender’s estate whilst future investment growth accrues outside the estate. The loan remains part of the lender’s estate unless repaid during their lifetime, providing no immediate IHT saving discounted gift trust arrangements, where the value of the gift for IHT purposes may be reduced to reflect the donor’s retained right to regular withdrawals. The discount depends on the donor’s age and health at the time of the gift.

Whilst this can reduce the immediate IHT charge on a chargeable lifetime transfer, the trust itself typically falls within the relevant property regime, with potential 10-year and exit charges, and charitable legacies can reduce the IHT rate from 40% to 36% on the taxable estate if at least 10% of the baseline amount (broadly the net estate after deducting available reliefs and exemptions) is left to qualifying charities, but also to achieve philanthropic objectives. Family office helps to integrate arrangements seamlessly for wealth maximisation.

Advanced Estate Structuring & Trust Planning

As UK inheritance tax planning becomes more complex and international tax compliance requirements continue to evolve, there is greater need for effective wealth transfer strategies. In order to optimise IHT outcomes across generations, family office coordinate complex estate structuring to utilise multiple trust arrangements. Family office help management of discretionary trusts, which are usually within the relevant property regime (subject to 10-year and exit charges), and interest-in-possession trusts.

Since 22 March 2006, most new interest in possession trusts fall within the relevant property regime, though certain categories such as immediate post-death interests, disabled person’s interests and transitional serial interests remain outside and offshore trust structures for non-UK assets, considering domicile and deemed-domicile rules. Since April 2017, protections apply for certain trusts settled before a settlor becomes deemed domiciled, but ‘tainting’ can remove those protections. Residence alone is not the determining factor for IHT exposure.

Family office help in effective IHT planning which involves comprehensive lifetime giving strategies that utilise annual exemptions, potentially exempt transfers, and  capital gains tax hold-over relief, available under section 165 TCGA 1992 for gifts of business assets and under section 260 TCGA 1992 for gifts that are immediately chargeable to IHT or would be but for available exemptions (such as into relevant property trusts). This is a CGT relief, not an IHT relief. These strategies are coordinated with broader succession planning to ensure that wealth transfer serves both tax efficiency and family governance objectives.

Family offices implement systematic gifting programmes that balance IHT savings with liquidity requirements, ensuring that families retain sufficient resources for their ongoing needs whilst maximising wealth transfer opportunities. This includes consideration of survivorship requirements and the strategic timing of transfers to optimise tax outcomes.
