IHT is charged on the value of your estate when you die, after taking account of any available reliefs and allowances.

For many families, two key tax-free allowances can reduce the amount of inheritance tax payable:

• the standard Nil Rate Band
• the Residence Nil Rate Band, which can apply when passing a main residence to direct descendants.

However, once the value of an estate exceeds £2 million, the Residence Nil Rate Band begins to reduce. This is known as the Residence Nil Rate Band taper.

For every £2 that your estate exceeds £2 million, £1 of your Residence Nil Rate Band is withdrawn. That means someone with an estate valued at £2.35 million could lose a significant proportion of this valuable allowance, while estates above a certain level might lose it altogether.

This often comes as a surprise because many people assume IHT allowances work in the same way regardless of the size of their estate.

There isn’t a single answer because every family’s circumstances are different.

The overall inheritance tax bill depends on several factors including:

• the total value of your estate
• whether you’re married or in a civil partnership
• whether unused allowances can be transferred from a spouse or civil partner
• how much of your estate includes your main residence
• who inherits your estate
• whether Business Relief or Agricultural Relief apply
• gifts you’ve made during your lifetime
• any charitable donations included in your Will.

This means two families with estates of exactly the same value could ultimately pay very different amounts of IHT.

At first glance, IHT planning can appear to be all about paying less tax. In practice, it’s much broader than that.

For many families, the bigger questions are:

• Can I help my children or grandchildren while I’m still alive?
• Should I gift assets now or keep them for later life?
• How do I balance enjoying my wealth with leaving a meaningful legacy?
• Could future care costs affect my plans?
• Will my partner have enough to live comfortably when I’m gone?

These aren’t questions that can be answered by a calculator. They’re life decisions.

The tax implications are important, but they form just one part of a much wider financial picture. That’s why many people choose to start planning years before IHT becomes an immediate concern.

Planning ahead gives you more time to explore your options, involve your family where appropriate and adjust your plans as your circumstances evolve.

When an estate grows beyond £2 million, one of the first questions people might ask is:

“So, how much inheritance tax will my family have to pay?”

It’s a perfectly reasonable question, but it’s rarely the right place to start. Inheritance tax depends on much more than the value of your estate. Family circumstances, ownership of assets and decisions made over many years can all influence the eventual bill.

To illustrate this, consider two families with estates of a similar value.

Although both families have estates worth more than £2 million, the planning opportunities, and the conversations they need to have, are completely different.

This illustrates why IHT planning is never just about reaching a particular financial threshold. It’s about understanding your family, your priorities and what you want your wealth to achieve.

There’s no shortage of online IHT calculators, guides and checklists. They’re useful for building a basic understanding of how inheritance tax works, but they can only ever tell part of the story.

They can’t tell you:

• whether gifting assets now could affect your long-term financial security
• how pension legislation might influence your estate planning
• whether trusts could be appropriate for your family
• how Business Relief or Agricultural Relief might apply
• whether changes to tax legislation could affect your plans in the future
• how one financial decision could unintentionally create consequences elsewhere.

That’s because inheritance tax doesn’t exist in isolation. It’s closely linked to retirement planning, investment strategy, cashflow, family circumstances and your wider financial objectives.

Making decisions in one area without considering the bigger picture can sometimes solve one problem while creating another.

For affluent families, this is where expert, tailored advice often becomes particularly valuable. An independent financial planner looks beyond individual products and tax-saving techniques to help you understand how every part of your financial life fits together.

IHT planning is often presented as a technical exercise involving tax allowances, exemptions and legislation. Those things matter, but they’re only part of the picture.

Before deciding how to pass on your wealth, it’s worth thinking about what you want it to achieve.

For some families, the priority is helping children onto the property ladder while they’re still alive. Others want to support grandchildren through education, protect a family business or leave money to charity. Equally, many people want the confidence to enjoy their own retirement without worrying they’re spending “too much”.

These goals aren’t mutually exclusive. The challenge is finding the right balance between enjoying your wealth today and leaving the legacy you want tomorrow.

That’s why IHT planning works best when it’s part of a wider financial plan rather than a standalone tax exercise.

At Amber River, this sits at the heart of our Life Landscaping approach. It starts by understanding what’s important to you, the future you want for your family and the life you want to lead. From there, a financial plan can be built that brings together retirement planning, investments, pensions, gifting and estate planning, rather than considering each decision in isolation.

If your estate is worth more than £2 million, IHT is likely to become an increasingly important consideration. But understanding how much your family could pay is only the beginning.

The bigger question is whether your financial plans reflect what matters most to you and the people you care about. Starting those conversations early gives you more time to consider your options, involve your family where appropriate and adapt your plans as circumstances or legislation change.

At what point does inheritance tax become more complicated?

While every estate is different, estates worth more than £2 million often require more detailed planning because the Residence Nil Rate Band can begin to taper away, potentially increasing the inheritance tax payable.

Can I reduce the inheritance tax my family might pay?

There are a range of legitimate planning strategies that could be appropriate, depending on your circumstances. These might include making gifts during your lifetime, reviewing how assets are owned, making use of available reliefs or restructuring your wider financial arrangements. The right approach will depend on your objectives as well as the tax rules, so professional advice is important.

Is inheritance tax planning only for very wealthy families?

Not necessarily. Many people become subject to inheritance tax because of rising property values, successful businesses or long-term investment growth rather than considering themselves especially wealthy. Reviewing your position regularly can help ensure your plans continue to reflect both your circumstances and current legislation.

Should I plan inheritance tax on my own?

There is plenty of useful information available online, and it’s a good place to build your understanding. However, inheritance tax planning often overlaps with retirement planning, investment strategy, pensions, trusts, gifting rules and succession planning. Decisions in one area can affect another, which is why many families choose to work with a financial planner who can consider the bigger picture rather than individual tax rules in isolation.
