If you own property in the UK, rising house prices could mean your inheritance tax bills will be higher than you expect. As property values increase, more estates exceed the tax-free thresholds. This means you or your family may owe significant inheritance tax unless careful planning is done.
The thresholds for inheritance tax have stayed mostly the same for years, while property prices have grown quickly, especially in high-value areas. Without taking action, you risk losing a large part of your estate to tax, which can affect how much wealth you pass on to your loved ones.
Understanding how rising property values impact inheritance tax is key to managing your estate effectively. Knowing your options and planning early can help reduce the financial strain on your family in the future.
Rising property values in the UK have made inheritance tax (IHT) liabilities more common, especially with tax thresholds unchanged for years. This affects who pays IHT and how much, with property often being the largest asset in an estate. Understanding these factors is key to managing your estate effectively.
Property prices have grown significantly over the last 15 years, with some regions seeing rises of over 60%. For example, average house prices outside London, in places like Hertfordshire and Manchester, have increased steadily.
This growth means your property may now be worth far more than when you first bought it. Higher values push estates above the £500,000 IHT threshold that applies in most cases, making more people liable for tax.
Even in areas with softer markets, like parts of London recently, values remain high enough to trigger IHT. This rise is a major driver behind the record £8.2 billion collected by HMRC in the 2024-25 year.
The nil-rate band (£325,000) and residence nil-rate band (£175,000) have been frozen since 2009. This means the amount you can leave tax-free has not kept up with inflation or property price increases.
With these fixed thresholds, growing property values automatically pull more estates into the IHT net. Estates that were safe from tax years ago might now owe substantial IHT due to this “fiscal drag”.
For married couples and civil partners, allowances can combine to £1 million if passing a home to direct descendants, but even this limit is strained in high-value markets. Without changes, expect more families to face tax bills as property prices keep rising.
Rising property values and frozen IHT thresholds are catching more than just the wealthiest. Middle-income families with modest homes in commuter towns or growth areas are increasingly liable.
Locations like St Albans and Guildford now have many estates above the tax threshold, despite not being traditionally “rich” areas. This shift means you cannot assume you are exempt from IHT based on income alone.
HMRC’s data shows more estates in this demographic paying IHT than ever before. Planning for IHT is essential to protect your family’s wealth, no matter your background or the size of your estate.
When property values increase but tax thresholds remain the same, more estates face inheritance tax (IHT). Knowing the specific allowances and how tax is calculated helps you manage your estate’s potential IHT liability. Recent and upcoming changes also affect how your estate and pensions are treated for tax.
The nil-rate band sets the amount of your estate exempt from IHT. For the 2024/25 tax year, this is £325,000. If your estate is below this, no tax is due.
For married couples or civil partners, unused nil-rate band portions can transfer, effectively doubling the threshold to £650,000.
You can also claim the residence nil-rate band (RNRB), which adds up to £175,000 per person when passing a main home to direct descendants. This means an individual could potentially have £500,000 tax-free allowance, or up to £1 million for a couple.
However, the RNRB phases out on estates over £2 million, reducing by £1 for every £2 above this limit, with no allowance beyond £2.35 million.
Inheritance tax is charged at 40% on the value of your estate above the combined nil-rate band and RNRB thresholds.
Your estate includes all property, money, possessions, and certain gifts made within seven years before death.
You may reduce the taxable estate by gifts that qualify as exemptions, trusts, or other reliefs recognised by HM Revenue and Customs (HMRC).
Spouse and civil partner transfers are usually exempt from IHT, which can help preserve allowances within the family.
Careful planning, such as lifetime gifting or trusts, can lower how much of your property’s value is subject to tax.
The IHT nil-rate thresholds have been frozen since 2009, but property values have risen sharply, causing more estates to exceed these limits.
From April 2027, unused pension funds and some pension death benefits are planned to be included in IHT calculations. This will affect many estates that previously avoided tax on pensions.
HMRC has forecasted that these changes could bring thousands of additional estates into IHT charge by 2030.
Although the IHT threshold is due to increase in April 2030, this may not fully offset the impact of rising house prices and inflation in the short term.
Staying informed about such changes is vital for you to update your estate plans and take advantage of allowances and reliefs.
When someone dies, the value of their property is crucial in deciding how much inheritance tax you might owe. HMRC often checks these values closely, especially if the properties are worth a lot or if the price declared seems too low. Understanding this process can help you prepare for potential tax investigations.
As an executor, you must report the entire value of the estate, including all properties, to HMRC. This value must be a fair market price at the date of death. You have a legal duty to ensure the declaration is accurate and complete.
If the declared value is too low, HMRC can investigate and ask for more tax. This is why it’s important to get professional valuations from qualified surveyors. You should provide HMRC with all the relevant details about the property, such as leases or agreements, to help support your valuation.
When HMRC suspects the value declared is incorrect, it can refer the case to the Valuation Office Agency (VOA). The VOA is responsible for checking if the property value is reasonable and may carry out physical inspections. This process usually lasts up to three months.
The VOA looks at factors like the property’s location, size, features, and any potential for development, including access to additional land. Sometimes, even small details can affect the value. The agency may ask you for more information or ask a surveyor to carry out a fresh valuation.
If HMRC and the executor disagree on the property’s value, this often leads to a formal investigation by the VOA. HMRC agreed with about half of the valuations last year, but it challenged many that seemed undervalued.
At this stage, it’s important to have two independent valuations from qualified surveyors to defend your reported value. This prevents a costly increase in the inheritance tax bill. The VOA’s report can result in higher valuations, increasing the amount you owe.
If you cannot resolve a valuation dispute with HMRC or the VOA, you may need to take the case to a First-tier Tribunal Hearing. This is a legal process where an independent judge reviews the evidence from both sides.
At the tribunal, you can present your valuations and any supporting documents. If the tribunal agrees with HMRC’s valuation, you must pay the revised tax amount. Being well prepared with clear, professional valuations improves your chances of success.
Managing inheritance tax for high-value or unique properties comes with specific hurdles. These include detailed scrutiny by tax authorities, difficulty in valuing properties with complex features or development rights, and well-known legal disputes that highlight common issues you might face.
When you own a high-value property, HM Revenue and Customs (HMRC) often examines your estate more closely. Properties in affluent areas can face detailed checks, especially if valuations seem low compared to market trends.
HMRC challenged over 7,500 inheritance tax cases recently, disputing property values in many. This means your estate could be called into question, potentially leading to increased tax bills if valuations are corrected.
Working with expert advisers, such as Evelyn Partners, can help ensure your property is properly valued and documented to withstand HMRC’s scrutiny.
If your property includes development potential, valuing it accurately becomes trickier. Future planning permissions or land use possibilities can raise the estate’s value, making it harder to estimate for inheritance tax purposes.
You must consider not only the current market price but also any rights or permissions that may increase its worth. These factors often require professional input from valuers familiar with local planning rules and markets.
NFU Mutual is known for advising clients with agricultural or rural properties, where development rights can influence valuations significantly. Getting expert help in these cases reduces risks of under- or over-valuation.
There have been several well-publicised cases where valuations of unique or luxury properties led to disputes with HMRC. These cases often involve disagreements over the true market value or the inclusion of additional features such as outbuildings or land parcels.
Such disputes show the importance of thorough estate planning and accurate valuations. If you own a unique property, be aware that any undervaluation could lead to larger tax bills and legal challenges later.
You can avoid these issues by engaging reputable professionals early and keeping clear records of your property’s value and any factors that affect it.
You can reduce your inheritance tax (IHT) bill by using specific allowances, planning lifetime gifts, setting up trusts, and taking out insurance policies. Each option targets different parts of your estate and offers ways to protect your assets from a large tax charge.
You should make full use of the nil-rate band, which is currently £325,000, and the residence nil-rate band worth up to £175,000 if you pass your main home to direct descendants. These allowances reduce the taxable value of your estate.
You can also benefit from annual exemptions that allow you to gift £3,000 tax-free each year. Smaller gifts up to £250 per person are exempt too. Charitable donations can reduce tax rates from 40% to 36% if you leave at least 10% of your estate to charity.
Reliefs may apply to certain assets, like business property or agricultural land, which can reduce their value for IHT purposes. Using these allowances and reliefs in combination can significantly lower your tax liability.
Gifting assets during your lifetime can help lower the value of your estate. Gifts made more than seven years before your death are usually exempt from IHT. You can gift assets directly or place them in trusts to remove them from your estate.
Trusts allow you to control how and when beneficiaries receive their inheritance while potentially reducing IHT. Different types of trusts exist, such as discretionary or interest-in-possession trusts, each with specific tax implications.
Be careful with gifts made less than seven years before death, as they may still be taxed. Proper planning and professional advice are crucial to ensure gifts and trusts effectively lower your inheritance tax.
Life insurance policies written in trust can provide funds to cover your IHT bill. This prevents beneficiaries from needing to sell assets, such as property, to pay the tax.
You can choose a policy that pays out a lump sum when you die, matching the expected inheritance tax liability. Having this cover in place ensures your estate retains its value and supports your heirs.
Ensure the policy is set up correctly, with a trust involved, so the payout doesn’t add to your estate and is paid quickly to your beneficiaries. This is a practical way to manage IHT costs without reducing your estate’s value through gifting or selling assets.
