Rising Property Values Drive More Estates into Inheritance Tax

January 15, 2026 – Surging property prices across the UK, particularly in London and the South East, are drawing an increasing number of estates into the scope of Inheritance tax (IHT), according to recent data and financial analysis.

The Growing Impact of Property Wealth

Property wealth now constitutes a critically important portion of estates subject to IHT. Recent figures indicate that property accounts for approximately 47% of the total value of estates paying IHT in London, and is approaching half nationally. this trend highlights the increasing impact of house price appreciation on IHT liabilities.

Regional Disparities

The burden of IHT is not evenly distributed across the country. London families are disproportionately affected, accounting for nearly a quarter of all IHT bills paid nationally.this is directly linked to the higher property values prevalent in the capital. Other regions with considerable property value increases are also seeing a rise in IHT contributions.

Current IHT Thresholds

The current IHT threshold stands at £325,000 per individual. This threshold has remained largely unchanged for several years, failing to keep pace with the rapid increase in property values. Married couples and civil partners can combine their thresholds, effectively doubling the allowance to £650,000. The Residence Nil Rate Band (RNRB),which provides an additional allowance for passing on a main residence to direct descendants,can increase this further,up to £950,000. However, the RNRB is subject to a taper for estates exceeding £2 million.

why Property Values Matter

The primary driver behind the increase in IHT liabilities is the sustained growth in property values. Many homeowners have seen substantial gains in the value of their properties over the past decade,pushing their estates above the IHT threshold. This is particularly true for those who have owned property for a long period, benefiting from long-term capital appreciation.

Planning for Inheritance Tax

With more estates becoming liable for IHT, proactive planning is crucial. Several strategies can be employed to mitigate IHT exposure:

• Gifting: Regularly gifting assets to beneficiaries can reduce the overall value of the estate. Annual gifting allowances exist, allowing individuals to gift up to £3,000 per year without incurring IHT.
• Life insurance: A life insurance policy written in trust can provide funds to cover IHT liabilities.
• Pension Planning: Pensions are generally exempt from IHT, making them an efficient way to pass on wealth.
• Trusts: Establishing trusts can help to remove assets from the estate and provide for beneficiaries.
• Property Downsizing: Downsizing to a less valuable property can reduce the overall estate value.

Seeking Professional Advice

Navigating IHT rules can be complex. It is highly recommended to seek professional financial advice from a qualified financial advisor or tax specialist to develop a tailored IHT plan that aligns with individual circumstances and goals.Early planning can make a significant difference in minimizing IHT liabilities and ensuring that assets are passed on to beneficiaries efficiently.
