As inheritance tax affects an increasing number of middle-class families and the associated bills climb, tax planning tools once primarily utilized by the wealthy are gaining traction.

Offshore bonds are emerging as a strategy for passing wealth across generations while potentially lowering tax liabilities. These financial instruments, often structured as life insurance policies managed by insurance companies in low-tax jurisdictions like the Isle of Man or Guernsey, allow for investment in assets such as shares and bonds. Ian Dyall, head of estate management at Evelyn Partners, noted a surge in demand for these products, stating that providers are struggling to keep up.

These bonds offer several tax advantages. Investment gains are not taxed immediately; instead, the tax liability is deferred until funds are withdrawn. This allows capital to remain invested, potentially leading to higher growth. Policyholders can typically withdraw up to 5% of the initial investment annually without immediate tax consequences. Unused portions of this allowance can be carried forward to subsequent years. When withdrawals are made, they are subject to income tax rather than capital gains tax. This allows individuals to time withdrawals during years with lower income, such as in retirement, to mitigate tax bills.

Offshore bonds can also be utilized for gifting wealth. The bond can be divided into numerous smaller segments, which can be transferred to family members at different times. This allows the original owner to retain control over the capital while distributing portions as desired. When a family member withdraws funds from a gifted segment, they are liable for income tax. However, if their overall income is low, this tax burden may be minimal. For instance, grandparents sometimes use these bonds to fund grandchildren's education. By gifting a segment, the tax liability within that segment can potentially be offset by the recipient's personal income tax allowance, which for individuals under 18 is £12,570 annually. This can allow funds to be used for educational expenses with little to no tax impact. Establishing such plans, particularly for minors, requires specialized trust structures and careful planning, with complexities that often mean grandparents, rather than parents, can facilitate such gifts without incurring their own tax liabilities.

While offshore bonds do not directly reduce inheritance tax, they can indirectly lower the taxable estate. Gifting a bond or its segments could be subject to inheritance tax if the donor dies within seven years, unless the bond is placed in a trust, removing it from their estate. This requires meticulous planning. The primary benefit lies in their function as a vehicle for holding wealth, from which an income can be drawn and segments distributed over time, thereby diminishing the value of the donor's estate.

Inheritance tax is levied at 40% on estates exceeding £325,000, with additional allowances for primary residences and transfers to spouses or civil partners. Gifting assets during one's lifetime can reduce this liability, but often involves uncertainty about future financial needs and longevity. Offshore bonds, particularly within structures like discounted gift trusts, address this by allowing individuals to gift assets while retaining access to funds. For example, a couple might invest in an offshore bond and gift it to their son via a discounted gift trust. If they survive seven years, the gift may be entirely free of inheritance tax. Even if they retain the right to fixed annual withdrawals, the taxable value of the gift is reduced by the amount of income expected to be taken, calculated actuarially. This can significantly lower the portion of the estate subject to inheritance tax.

Despite their potential benefits, these products are complex and can be susceptible to scams. It is crucial for individuals to ensure that any firm they engage with is regulated by the Financial Conduct Authority and to fully understand all fees and exit penalties. While the investment providers are typically large, stable companies, investors are not covered by the Financial Services Compensation Scheme if a provider fails. Engaging a reputable, fee-based financial adviser is recommended to ensure the product aligns with individual family circumstances and financial goals. Offshore bonds are not universally beneficial; in some situations, they can lead to higher tax bills, particularly if large sums are cashed out by higher-rate taxpayers. Some experts suggest that for certain families, a conventional investment account within a trust might offer greater simplicity and transparency, avoiding potential future deferred tax liabilities.
