Inheritance Tax (IHT) remains one of the most significant drains on family wealth in the UK. With estates taxed at 40% on assets above the nil rate bands (potentially adding up to a tax-free allowance of £500,000 per person, or £1m for couples), many families are surprised by how quickly property values and investments can push them beyond these thresholds.
Additionally, from April 2027, pensions will count towards your estate for IHT purposes, which will push many people above the nil rate bands and potentially reduce the nil rate band available against your main property, this is creating a liability where there may not have been one before. This, coupled with rising house prices and increasingly complex legislation, mean that estate planning, particularly around inheritance tax, is now more relevant and important than ever.
This isn’t just a concern for the very wealthy – as of January 2026, the average house price in the UK came in at £368,031 (Rightmove). If you’re someone who has worked hard to buy a home and build up a good pension, there’s now a very high chance that 40% of the value of your estate will be due to the tax man upon your death. Inheritance tax planning has become an essential part of sensible financial planning for anyone who wishes to preserve wealth for future generations.
For decades, Trusts and inheritance tax planning have gone hand in hand. But while Trusts remain a well-established and effective solution, alternative approaches such as offshore bonds are increasingly being used alongside (or in some cases instead of) traditional Trust structures, as they can offer greater tax efficiency, flexibility, and long-term growth potential.
Here we’ll explain both options, breaking down how Trusts and offshore investment bonds work and how they may be used separately or together to protect your estate more effectively.
What is a Trust?
A Trust is a legal arrangement that separates ownership of assets from the benefit of those assets. In the simplest terms, it works like this:
- The settlor places assets (such as cash, property, investments, or bonds) into the Trust
- Trustees are appointed to manage those assets, on behalf of both the settlor and the beneficiaries
- At the appropriate time determined by the trustee, the beneficiaries receive the benefit
- Once assets are transferred into Trust, they are generally no longer considered part of the settlor’s estate for inheritance tax purposes, subject to certain rules and time limits.
Trusts are widely used in estate planning to protect wealth, maintain control over how funds are distributed and reduce exposure to inheritance tax.
How Trusts Help Reduce Inheritance Tax
The effectiveness of Trust planning often relies on the Seven-Year Gifting Rule.
Under the Seven-Year Rule, assets gifted outright or placed into Trust generally become exempt from inheritance tax after seven years. If death occurs before the seven years have elapsed, taper relief may gradually reduce the liability.
Other useful allowances that can help towards reducing your IHT liability include:
- Small gift allowances and the annual gift exemption of £3,000 per individual, which can be useful within a carefully planned gifting strategy
- The residence nil rate band, which provides up to an additional £175,000 when a home is passed to direct descendants
Careful timing and planning can significantly increase the effectiveness of these exemptions. It’s especially important to consider IHT planning within the wider context of your financial plan and wealth management strategy, to ensure that every area of your finances works together harmoniously.
Different Types of Trusts and Their Uses
There are several types of Trust, each designed to meet different planning needs. Each structure offers a different balance between control, access, and tax effectiveness.
Some of the most common types that are used within the context of inheritance tax planning are:
Gift Trusts
With a Gift Trust, assets are given away outright. After seven years, they typically fall outside the settlor’s estate for inheritance tax purposes. These are most suitable when access to the capital is not required.
Discounted Gift Trusts
This type of Trust allows an immediate reduction in inheritance tax exposure while still providing regular withdrawals. These are often attractive to retirees who need an income but wish to reduce the value of their estate.
Loan Trusts
Rather than gifting assets, the settlor lends money to the Trust. The original loan can be repaid when required, while any future growth remains inside the Trust and therefore outside the estate.
Trusts can be set up under two different structures:
Discretionary Trusts
Trustees decide who the beneficiaries are, which can change over time – for example, adding new family members such as grandchildren. They also decide when the beneficiaries receive the assets, and how much they get. This provides flexibility and protection, particularly for younger beneficiaries or where circumstances may change. They are often used for multi-generational wealth planning and are the most common type of Trust that we work with at Tideway.
Absolute Trusts
Offer less flexibility and reduce the control of the trustees compared to a discretionary trust where beneficiaries are set and fixed at outset, however these can be more tax efficient and suitable in certain circumstances.
Things to Consider When Using Trusts
Trusts can be helpful tools when it comes to estate planning and intergenerational wealth planning, especially for more complex family situations. They offer the potential to reduce your estate value for IHT purposes, protection for your assets, and – depending on the type of Trust – provide control over when your beneficiaries inherit the assets inside.
As with any methods of wealth management, there are of course a few things to consider. Trusts can be complex to set up and manage and are subject to specific legal and tax reporting requirements. This introduces a layer of legal and administrative complexity, which in most cases will require professional support to set up and manage, leading to additional costs and charges. There is also the consideration of the impact on your tax position.
For some families, these obligations can feel onerous, especially where simpler alternatives may achieve similar objectives.
What is an Offshore Investment Bond?
Offshore bonds are an attractive solution for those looking to optimise their tax position, access a diverse range of investment options, plan for succession, and grow their wealth over time.
An offshore investment bond is an insurance-based investment wrapper issued by an offshore life company. The key advantage is gross roll-up, which allows investments to grow largely free from UK tax while inside the bond. Without annual tax deductions, returns can compound more effectively over time.
Offshore bonds also offer a wide choice of investments, flexible access to capital, structured income options, and, most importantly, estate planning opportunities. In essence, they act as highly effective tax wrappers for long-term wealth accumulation.
Additionally, offshore bonds can be used in conjunction with Trusts, to create a highly effective estate planning solution. You can learn more about this dynamic pairing in our previous article.
Tax Advantages of Offshore Bonds
Offshore bond taxation provides several distinct benefits, which together can significantly enhance your tax efficiency:
- Tax deferral – No immediate tax is due on gains or portfolio rebalancing, allowing investments to grow more efficiently and benefit from compounding.
- 5% withdrawal allowance – Up to 5% of the original investment can be withdrawn each year without an immediate tax charge. This can provide useful supplementary income.
- Top-slicing relief – When gains are eventually realised, this relief can reduce income tax by spreading the gain across the number of years the bond has been held.
- Segmentation and assignment flexibility – Individual segments of the bond can be assigned to beneficiaries, who may pay tax at lower rates, reducing the overall tax burden. This can also be a smart way to pass on assets in a tax-efficient and controlled manner – more on that in a moment.
Offshore Bonds in Estate Planning
Offshore bonds can play a powerful role in estate planning, particularly when combined with Trusts. Placing an offshore bond into a Trust can remove future growth from the settlor’s estate and decrease their IHT liability (subject to the Seven Year Rule).
This structure can also provide controlled access to income, which is particularly useful for situations in which it’s pertinent to remove the value from your estate sooner rather than later, but where you may not be ready for your beneficiaries to receive it immediately.
Perhaps most importantly for estate planning purposes, placing an offshore bond into a Trust can facilitate gradual gifting. This can be achieved using bond segmentation, which involves dividing the bond value into segments which can then be assigned individually to beneficiaries over time. This allows wealth to be transferred in a controlled and tax-efficient manner.
This level of flexibility is often difficult to replicate using traditional investments, which makes the unique combination of offshore bonds and Trusts a particularly powerful tool for inheritance tax planning.
Both solutions can be effective, but they serve slightly different purposes.
| Feature | Trusts | Offshore Bonds |
| Primary Purpose | Asset protection and control | Tax-efficient income and growth |
| Tax Treatment | Estate removal | Tax deferral and gross roll up |
| Flexibility | Structure dependent | Highly flexible |
| Administration | More complex | Typically simpler, but requires professional assistance |
| Income Access | Often limited | 5% annual withdrawals |
| Costs | Legal and periodic charges | Product and management costs |
Trusts remain a valuable and proven tool in Trusts and inheritance tax planning, particularly where control and asset protection are priorities. However, they can involve complexity and ongoing administration. Offshore bonds offer a flexible alternative, providing tax deferral, gross roll-up growth, and adaptable estate planning solutions.
As we’ve explored, in many cases the most effective strategy is combining both to create a coordinated financial plan that supports wealth preservation, IHT planning, and proactive estate management.
Examples of scenarios that could benefit from this production combination could be:
A retired couple needing income
- The couple can place an offshore bond within a discounted gift Trust.
- Regular withdrawals will supplement their lifestyle while future growth sits outside their estate.
The younger investor planning ahead
- They may use an offshore bond alone initially to benefit from gross roll-up and long-term compounding.
- Later on, as their wealth grows and their tax planning needs increase, they can assign segments to children as gifts.
Family with multi-generational wealth
- The family can combine Discretionary Trusts with offshore bonds to balance control, protection and tax efficiency, ensuring wealth is passed on gradually and responsibly.
- Segmentation can help them to pass on the wealth at a pace that suits their overall wealth management strategy and their family dynamic.
Effective inheritance tax planning begins with clarity. Once you have a clear picture of your entire financial position, it’s possible to identify where the best and most lucrative opportunities for inheritance tax mitigation lie.
A qualified wealth manager will be able to map this out with you and provide the best advice for your specific needs, taking into account important factors such as:
- The value of your estate and available inheritance tax thresholds
- Your income requirements
- When and how you’d like your beneficiaries to inherit
- Other opportunities to improve tax efficiency
Since Trusts and offshore bonds both involve technical rules and long-term implications, professional advice is essential. In fact, current rules dictate that you cannot set up an offshore bond as an individual and must do so through a regulated financial institution. Tideway can set up offshore bonds on behalf of our clients.
